0006Specific exemplary embodiments are described below so that the principles of structure, function, manufacture, and use of the devices and methods disclosed herein are comprehensively understood. One or more embodiments of these exemplary embodiments are illustrated in the accompanying drawings. The devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments, and the scope of the various exemplary embodiments of the invention is defined only by claim. Will be understood by those skilled in the art. The features illustrated or described in connection with one exemplary embodiment may be combined with the features of another exemplary embodiment. Such modifications and modifications shall be included within the scope of the present invention.
0007FIG. 1 shows a master controller 12 used in connection with the robot arm slave cart 20 of the type shown in FIG. The master controller 12, the robot arm slave cart 20, and their individual components and control system are collectively referred to herein as the robot system 10. Examples of such systems and devices are disclosed in US Pat. No. 7,524,320, incorporated herein by reference. Accordingly, various details of such devices will not be described in detail herein beyond what may be necessary to understand the various exemplary embodiments disclosed herein. .. As is well known, the master controller 12 is generally gripped by the surgeon and manipulated through space while the surgeon observes the procedure through the stereoscopic display 16 (represented as 14 overall in FIG. 1). ) Including. The master controller 12 generally moves with more than one degree of freedom and further has an actuable handle for activating the tool (eg, closing the grasping jaw, applying an electric potential to the electrodes, etc.). Often equipped with a manual input device.
0008As can be seen in FIG. 2, the robot arm cart 20 is configured to activate a plurality of surgical tools designated as 30 overall. US Pat. No. 6,132,368, the title of the invention, "Multi-Component Telepresence System," which various robotic surgery systems and methods using a master controller and robotic arm cart configuration are incorporated herein by reference in their entirety. and It is disclosed in "method". As shown, the robot arm cart 20 includes a base 22, from which three surgical tools 30 are supported in the illustrated embodiment. Each surgical tool 30 is supported by a series of manually articulating link mechanisms, commonly referred to as setup fittings 32, and a robot manipulator 34. As used herein, these structures are shown with a protective cover that extends over most of the robot linkage. These protective covers may be arbitrary and avoid collisions by minimizing the inertia applied to the servo mechanisms used to operate such devices and limiting the volume of movable components. However, in order to limit the weight of the entire cart 20, the size may be limited or eliminated altogether. The cart 20 generally has dimensions suitable for transporting the cart 20 between operating rooms. The cart 20 is typically configured to pass through a standard operating room door and be placed in a standard hospital elevator. The cart 20 preferably has a constant weight and includes a wheel (or other transport) system that allows one attendant to position the cart 20 adjacent to the operating table.
0009Next, referring to FIG. 3, the illustrated robot manipulator 34 includes a link mechanism 38 that constrains the movement of the surgical tool 30. Linkage 38 ensures that the surgical tool 30 rotates about a point 40 in space, as described in more detail in US Pat. No. 5,817,084, which is incorporated herein by reference in its entirety. Includes rigid links that are connected together by a rotary joint in a parallelogram configuration. Due to this parallelogram configuration, rotation is constrained to swirl around axis 40a, sometimes referred to as the pitch axis. Since the link supporting the parallelogram linkage is swivelly attached to the setup fitting 32 (FIG. 2), the surgical tool 30 rotates further about the axis 40b, which is sometimes referred to as the yaw axis. The pitch axis and yaw axes 40a, 40b intersect at a remote center 42 aligned along axis 44 of the surgical tool 30 . The surgical tool 30 may have additional degrees of freedom to be driven supported by the manipulator 50, including the sliding motion of the surgical tool 30 along the longitudinal tool axis "LT-LT". As the surgical tool 30 slides relative to the manipulator 50 along the tool axis LT-LT (arrow 40c), the remote center 42 remains anchored to the base 52 of the manipulator 50. Therefore, the entire manipulator generally moves to reposition the remote center 42. The link mechanism 54 of the manipulator 50 is driven by a series of motors 56. These motors actively move the linkage 54 in response to commands from the processor of the control system. Motor 56 is also used to operate the surgical tool 30. An alternative setup joint structure is shown in Figure 4. In this embodiment, the surgical tool 30 is supported by an alternative manipulator structure 50'between the two tissue manipulation tools.
0010Other embodiments include a wide variety of alternative robotic structures, including those described in US Pat. No. 5,878,193, the title of the invention, "Automated Endoscope System For Optimal Positioning," which is incorporated herein by reference in its entirety. May be incorporated. In addition, the data communication between the robot component and the processor of the robotic surgery system is described in relation to the communication between the surgical tool 30 and the master controller 12, but the manipulator, setup fitting, Circuit mechanisms such as endoscopes or other imaging devices and component compatibility assessment, component type identification, component calibration (offset, etc.) communication, component connectivity to robotic surgery systems Similar communication may be performed with the processor of the robotic surgery system that performs the above.
0011Figure 5 shows a surgical tool 100 that is well adapted for use with the robot system 10. As can be seen in the drawing, the surgical tool 100 includes a surgical end effector 1000 with an end cutter. The surgical tool 100 includes an elongated shaft assembly 200 that is operably connected to the manipulator 50 by a tool mounting portion, generally designated as 300 overall. The surgical tool 100 further includes an interface 302 that mechanically and electrically connects the tool mounting portion 300 to the manipulator. One interface 302 is shown in Figures 6-10. In the embodiments shown in FIGS. 6-10, the tool mounting portion 300 comprises a plurality of rotatable body portions (four are shown in FIG. 10), a pair of pins 308 extending from the surface of the driven element 306. Includes a tool mounting plate 304 that operably supports the driven disk or element 306, respectively. One pin 308 is closer to the axis of rotation of each driven element 306 than the other pin 308 on the same driven element 306, which helps ensure a positive angular alignment of the driven element 306. ing. The interface 302 may include an adapter portion 310 configured to engage the mounting plate 304 in a mountable manner, as further discussed below. The illustrated adapter portion 310 includes an array of electrical connection pins 312 (FIG. 8) that may be connected to the memory structure by a circuit board within the tool mounting portion 300. Interface 302 is described herein in relation to mechanical, electrical, and magnetic coupling elements, but in other embodiments, a variety of telemetry modes, including infrared, inductively coupled, and the like. Please understand that may be used.
0012As seen in FIGS. 6-9, the adapter portion 310 generally includes a tool side 314 and a holder side 316. The plurality of rotatable bodies 320 are mounted on a floating plate 318, which has a limited range of movement for a peripheral adapter structure perpendicular to the main surface of the adapter 310. Axial movement of the floating plate 318 helps to disconnect the rotatable body 320 from the tool mount 300 when a lever or other latch structure is actuated along the sides of the tool mount housing (not shown). Other embodiments may use other mechanisms / configurations for detachably connecting the tool mounting portion 300 to the adapter 310. In the embodiments of FIGS. 6-10, the rotatable body 320 is elastically mounted on the floating plate 318 by an elastic radial member extending into a circumferential recess around the rotatable body 320. Will be done. The rotatable body 320 can move in the axial direction with respect to the plate 318 due to the bending of these elastic structures. When disposed in the first axial position (towards the tool side 314), the rotatable body 320 can rotate freely with no angle restrictions. However, as the rotatable body 320 moves axially towards the tool side 314, the tab 322 (which extends radially from the rotatable body 320) laterally engages the stalls on the floating plate. This limits the angular rotation of the rotatable body 320 around those axes. By using such restricted rotation, the drive pin 322 pushes the rotatable body 320 into the restricted rotation position until the pin 332 is aligned with (and slides into) the opening 334'. As such, the rotatable body 320 can be helped to driveably engage the drive pin 332 of the corresponding tool holder portion 330 of the robot system 10. The opening 334 on the tool side 314 and the opening 334'on the holder side 316 of the rotatable body 320 are two driven elements 306 (FIG. 10) of the tool mounting portion 300. It is configured to align exactly with the drive element 336 of the holder 330. As mentioned above with respect to the inner and outer pins 308 of the driven element 306, the openings 334, 334'are at different distances from the axis of rotation on their individual rotatable bodies 306 so that alignment is from their intended position. It is guaranteed that it will not reach 180 degrees. In addition, each of the openings 334 may be slightly radially elongated to tightly accept the pin 308 in the circumferential direction. This allows the pin 308 to slide radially within the opening 334 and adapts to some degree of axial misalignment between the tool 100 and the tool holder 330 while with the driving element. It is possible to minimize any angular misalignment and backlash with the driven element. The opening 334 of the tool side 314 may be offset by about 90 degrees from the opening 334'(shown by the dashed line) of the holder side 316, as is most clearly seen in FIG.
0013In the embodiments of FIGS. 6-10, the array of electrical connector pins 340 is located on the holder side 316 of the adapter 310, and the tool side 314 of the adapter 310 receives a pin array (not shown) from the tool mounting portion 300 (not shown). Figure 9) is included. In addition to transmitting electrical signals between the surgical instrument 100 and the tool holder 330, at least some of these electrical connections are connected to the adapter storage device 344 (FIG. 8) by the circuit board of the adapter 310. You may.
0014In the embodiments of FIGS. 6-10, a separable latch configuration 346 is used to detachably secure the adapter 310 to the tool holder 330. As used herein, the term "tool-driven assembly", when used in the context of robotic system 10, includes at least adapter 310 and toolholder 330, collectively as 110 in FIG. It is specified. As seen in FIG. 6, the tool holder 330 includes a first latch pin configuration 337 sized to accommodate the corresponding clevis slot 311 provided in the adapter 310. In addition, the tool holder 330 further has a second latch pin 338 sized to be held within the corresponding latch clevis 313 of the adapter 310. See Figure 8. The latch assembly 315 is movably supported on the adapter 310 to form a pair of latch clevis 317s, the latch clevis 317 being the first latch in which the latch pins 338 are held within their individual latch clevis 313. From the fastening position, the clevis 317 can be urged to the unlatch position where it is aligned with the clevis 313, and the second latch pin 338 can be inserted into or removed from the latch clevis 313. One or more springs (not shown) are used to urge the latch assembly to the latching position. The lip on the tool side 314 of the adapter 310 slidably accommodates a laterally extending tab of the tool mounting housing (not shown).
0015Next, referring to FIGS. 5 and 11-16, the tool mounting portion 300 provides various forms of control movement required to operate a particular type of end effector connected to the distal end of the elongated shaft assembly 200. Operablely support multiple drive systems to generate. As shown in FIGS. 5 and 11-13, the tool mounting portion 300 accepts the corresponding "first" rotational power motion from the tool driven assembly 110 of the robot system 10 and surgically performs that first rotational power motion. Includes a first drive system, collectively designated as 350, configured to transform into a first rotational control motion applied to the end effector. In the illustrated embodiment, the first rotation control motion is used to rotate the elongated shaft assembly 200 (and the surgical end effector 1000) around the longitudinal tool axis LT-LT.
0016In the embodiments of FIGS. 5 and 11-13, the first drive system 350 is a tubular gear (or attached to) formed at (or attached to) the proximal end of the proximal closed tube segment 202 of the elongated shaft assembly 200. tube gear) Contains segment 354. The proximal end 208 of the proximal side tube segment 202 is rotatably supported on the tool mounting plate 304 of the tool mounting portion 300 by a front support cradle 352 mounted on the tool mounting plate 304. See Figure 11. The tubular gear segment 354 is supported by meshing engagement with a first rotary gear assembly 360 that is operably supported on the tool mounting plate 304. As seen in FIG. 11, the rotary gear assembly 360 has a corresponding number of driven discs or elements 306 on the adapter side 316 of the tool mounting plate 304 when the tool mounting portion 300 is connected to the tool driving assembly 110. It comprises a first rotary drive gear 362 connected to one. See Figure 10. The rotary gear assembly 360 further comprises a first rotary driven gear 364 that is rotatably supported on the tool mounting plate 304. The first rotary driven gear 364 meshes with the second rotary driven gear 366, and the gear 366 meshes with the tubular gear segment 354. The rotation of the rotary drive gear 362 is triggered by the first rotational output motion being applied from the tool drive assembly 110 of the robot system 10 to the corresponding driven element 306. The rotation of the rotary drive gear 362 is ultimately represented by the rotation of the elongated shaft assembly 200 (and the surgical end effector 1000) around the longitudinal tool axis LT-LT (indicated by the arrow "R" in FIG. 5). ) Brings. Rotational output from the tool-driven assembly 110 When applied in a certain direction, rotation of the elongated shaft assembly 200 and the surgical end effector 1000 around the longitudinal tool axis LT-LT is provided in the first rotational direction. It will be recognized that when the rotational power motion is applied in the opposite direction, the rotation of the elongated shaft assembly 200 and the surgical end effector 1000 is brought about in a second direction opposite to the first direction of rotation.
0017In the embodiments of FIGS. 5 and 11-16, the tool mounting portion 300 accepts the corresponding "second" rotational power motion from the tool driven assembly 110 of the robot system 10 and uses that second rotational power motion for surgery. It further includes a second drive system, collectively designated as 370, configured to translate into a second rotational control motion applied to the end effector. The second drive system 370 is coupled to the corresponding second of the driven disc or element 306 on the holder side 316 of the tool mount plate 304 when the tool mount portion 300 is coupled to the tool drive assembly 110. Includes a second rotary drive gear 372. See Figure 10. The second drive system 370 further comprises a first rotary driven gear 374 that is rotatably supported on the tool mounting plate 304. The first rotary driven gear 374 meshes with a shaft gear 376 mounted movably and non-rotatably on the proximal drive shaft segment 380. In this illustrated embodiment, the shaft gear 376 is non-rotatably mounted on the proximal drive shaft segment 380 by a series of axial keyways 384, by which the keyway 384 causes the shaft gear 376 to be proximal. It can move in the axial direction on the segment 380 while being non-rotatably fixed to the side drive shaft segment 380. The rotation of the proximal drive shaft segment 380 transmits a second rotational control motion to the surgical end effector 1000.
0018The second drive system 370 in the embodiments of FIGS. 5 and 11-16 is a proximal drive shaft segment 380 that moves the shaft gear 376 to engage and disengage with the first rotary driven gear 374. Includes a shift system 390 that selectively shifts in the axial direction. For example, as seen in FIGS. 11-13, the proximal drive shaft segment 380 allows the proximal drive shaft segment 380 to move axially and rotate with respect to the second support cradle 382. It is supported within a second support cradle 382 mounted on the axial tool mounting plate 304. In at least one form, the shift system 390 further includes a shifter yoke 392 slidably supported on the tool mounting plate 304. Since the proximal drive shaft segment 380 is supported within the shifter yoke 392 and has a pair of collars 386 on the segment, shifting the shifter yoke 392 on the tool mounting plate 304 is of the proximal drive shaft segment 380. Brings axial movement. In at least one form, the shift system 390 further includes a shifter solenoid 394 that operably interfaces with the shifter yoke 392. The shifter solenoid 394 receives control power from the robot controller 12, whereby when the shifter solenoid 394 is started, the shifter shifter yoke 392 moves in the distal "DD" direction.
0019In this illustrated embodiment, the shaft spring 396 is pivotally supported on the proximal drive shaft segment 380 between the shaft gear 376 and the second support cradle 382 to bring the shaft gear 376 in the proximal direction "PD". , To mesh and engage with the first rotary driven gear 374. See Figures 11, 13 and 14. The rotation of the second rotary drive gear 372 in response to the rotational output motion generated by the robot system 10 ultimately results in the proximal drive shaft segment 380 and other drive shaft components connected to it (drive). The shaft assembly 388) rotates about the longitudinal tool axis LT-LT. When the rotational output motion from the tool drive assembly 110 is applied in one direction, the rotation of the proximal drive shaft segment 380, and finally the rotation of the other drive shaft components attached to it, also in the first direction. It will be recognized that when the rotational power motion is applied in the opposite direction, the rotation of the proximal drive shaft assembly 380 is brought about in the second direction opposite to the first direction. As discussed in more detail below, when it is desirable to shift the proximal drive shaft segment 380 in the distal "DD" direction, the robot controller 12 activates the shifter solenoid 390 to displace the shifter yoke 392 distally. Shift in the direction "DD".
002017 and 18 show another embodiment using the same components as the embodiments shown in FIGS. 5 and 11-16, but this embodiment is rotationally driven relative to the proximal drive shaft segment 380. The difference is that a battery-powered drive motor 400 is used to supply the motion. Such a configuration allows the tool mounting portion to generate higher rotational power motion and torque, which may be advantageous when different forms of end effectors are used. As seen in those drawings, the motor 400 is attached to the tool mounting plate 304 by the support structure 402 so that the drive gear 404 connected to the motor 400 is held in meshing engagement with the shaft gear 376. .. In the embodiments of FIGS. 17 and 18, the support structure 402 is designed to facilitate mounting of the housing member (not shown) to the mounting plate 304 when the motor 400 is not in use, the tool mounting plate 304. The latch notch 303 formed in the above is configured to be disengageably engaged. Therefore, to use the motor 400, the clinician removes the housing from the tool mounting plate 304 and then inserts the leg body 403 of the support structure into the latch notch 303 of the tool mounting plate 304. The proximal drive shaft segment 380 and other drive shaft components attached to it rotate about the longitudinal tool axis LT-LT by powering the motor 400. As shown, the motor 400 is battery powered. However, in such a configuration, the motor 400 is interfaced with the robot controller 12, so that the robot system 10 controls the start of the motor 400. In an alternative embodiment, the motor 400 can be manually actuated by an on / off switch (not shown) mounted on the motor 400 itself or on the tool mounting portion 300. In yet another embodiment, the motor 400 may accept power and control signals from the robot system.
0021The embodiments shown in FIGS. 5 and 11-16 are for manually applying reverse rotational motion to the proximal drive shaft segment 380 in the event of motor failure or power loss or interruption to the robot system. Includes a manually operable reversal system, designated as 410 overall. Such a manually actuable reversing system 410 also provides when the drive shaft assembly 388 becomes stuck or otherwise solidified, for example, in a manner that prevents the drive shaft components from rotating backwards solely with the power of the motor. May be particularly useful for. In the illustrated embodiment, the mechanically actuable reversing system 410 is selectively engageable with the second rotary driven gear 376 and has a counter-rotating motion with respect to the proximal drive shaft segment 380. Includes drive gear assembly 412, which can be manually actuated to add. The drive gear assembly 412 includes a reversing device 414 movably mounted on the tool mounting plate 304. The reversing device 414 is rotatably supported on a swivel shaft 416 movably mounted on the tool mounting plate 304 through slot 418. See Figure 12. In the embodiments of FIGS. 5 and 11-16, the manually actuable reversing system 410 further includes a manually actuable drive gear 420 including a body portion 422 in which a bow-shaped gear segment 424 is formed. Since the main body portion 422 selectively swivels around the actuator axis AA (FIG. 11) substantially perpendicular to the tool mounting plate 304, it is rotatably connected to the tool mounting plate 304.
0022Figures 11-14 show the manually actuable reversal system 410 in the first non-actuated position. In one exemplary embodiment, the actuator handle portion 426 is formed on or otherwise attached to the body portion 422. The actuator handle portion 426 is such that a small amount of interference is established between the handle portion 426 and the tool mounting plate 304 to hold the handle portion 426 in the first non-actuated position with respect to the tool mounting plate 304. The size is decided. However, when the clinician wants to manually actuate the drive gear assembly 412, the clinician can easily overcome the tight fit by applying a swivel motion to the handle portion 426. As also seen in FIGS. 11-14, when the drive gear assembly 412 is in the first non-actuated position, the arched gear segment 424 is disengaged from the meshing engagement with the reversing device 414. When the clinician wants to apply a counter-rotating drive motion to the proximal drive shaft segment 380, the clinician begins to apply a swivel ratchet motion to the drive gear 420. As the drive gear 420 begins to rotate about the working shaft AA, a part of the main body 422 comes into contact with a part of the reversing device 414, and the reversing device 414 is moved in the axial direction in the distal direction DD to move the driving shaft gear 376. Is engaged and disengaged from the meshing engagement of the second drive system 370 with the first rotary driven gear 374. See Figure 15. As the drive gear 420 turns, the bow-shaped gear segment 424 meshes with the reversing device 414. By continuing to move the drive gear 420 gradually, reverse rotation drive motion is applied to the drive shaft gear 376 and finally to the proximal drive shaft segment 380. The clinician may continue to gradually move the drive gear assembly 412 as many times as necessary to completely release or reverse the associated end effector component (one or more). Once the desired amount of counter-rotation is applied to the proximal drive shaft segment 380, the clinician will tell that the bow-shaped gear segment 416 is the drive shaft gear 376. The drive gear 420 is returned to the starting position or the non-operating position which is disengaged from the meshing engagement with. When in that position, the shaft spring 396 again urges the shaft gear 376 to mesh and engage with the first rotary driven gear 374 of the second drive system 370.
0023Upon use, the clinician may enter control commands into the controller or control unit of robot system 10, which robot system 10 ultimately communicates to the various components of the second drive system 370. The output motion to be performed is "generated by robot control". As used herein, the terms "robot-controlled" or "robot-controlled" are generated by powering and controlling motors and other electrically driven components of a robot system. Refers to the movement to be done. These terms refer to actions performed by a clinician that result in control movements that occur independently of the movements that occur by powering the motors of a robotic system, "manual operation". It is distinguishable from the terms "possible" or "manually generated". By adding the control motion generated by the robot control to the second drive system in the first direction, the first rotational drive motion is added to the drive shaft assembly 388. When the drive shaft assembly 388 is rotated in the first rotational direction, the launch member 1200 is driven distally "DD" from its start position to its end position within the end effector 1000. By adding the control motion generated by the robot control to the second drive system in the second direction, the second rotational drive motion is added to the drive shaft assembly 388. When the drive shaft assembly 388 is rotated in the second direction of rotation, the launching member 1200 is driven in the end effector 1000 in a proximal direction "PD" from its end position to its start position. When the clinician wants to manually add rotational control motion to the drive shaft assembly 388, the drive shaft assembly 388 rotates in a second direction of rotation, which causes the launcher 1200 to move in the proximal direction "PD" within the end effector. To do. In other embodiments that include the same components, the drive shaft assembly can be rotated in a first direction of rotation by manually adding a rotation control motion to the drive shaft assembly, and that rotation is used to control the robot. The control motion generated in
0024Manually actuating and shifting the drive shaft assembly used to fire, close, and rotate the end effector, causing the motor (one or more) to fail, the robot system to lose power, or something else. Even in the event of an electronic failure, the end effector can be released and removed from the surgical site as well as the abdomen. By actuating the handle portion 426, an actuating or controlling force is manually generated and the force is applied to the drive shaft assembly 388'by various components of the manually actuable reversing system 410. When the handle portion 426 is in its inactive state, it is urged to disengage from its operable engagement with the reversing device 414. The bias is shifted by starting the operation of the handle portion 426. The handle 426 is configured to repeat the operation as many times as necessary to completely release the launching member 1200 and the end effector 1000.

That is, when the third drive pulley 432 is rotated in the first rotation direction, the cable end 434A moves in the distal direction "DD" and the cable end 434B moves in the proximal direction "PD". As the third drive pulley 432 rotates in the opposite direction of rotation, the cable end 434A moves in the proximal direction "PD" and the cable end 434B moves in the distal direction "DD".
0026The tool-mounted portion 300 shown in FIGS. 5 and 11-16 accepts the corresponding "fourth" rotational power motion from the tool-driven assembly 110 of the robot system 10 and performs its fourth rotational power motion as a fourth rotation. Includes a fourth drive system 450 configured to transform into control motion. The fourth drive system 450 is coupled to the corresponding fourth of the driven disc or element 306 on the holder side 316 of the tool mount plate 304 when the tool mount portion 300 is coupled to the tool drive assembly 110. Includes a fourth drive pulley 452. See Figure 10. The fourth drive pulley 452, relative to the corresponding fourth drive cable 454, may be used to apply various control or manipulative movements to the end effector operably coupled to the shaft assembly 200. It is configured to add a fourth rotational control motion (according to the corresponding rotational output motion applied to the pulley by the robot system 10). As most notably seen in FIGS. 11 and 12, the fourth drive cable 454 extends around the fourth drive spindle assembly 456. The fourth drive spindle assembly 456 is rotatably mounted on the tool mounting plate 304, and the fourth tension spring 458 is mounted between the fourth drive spindle assembly 456 and the tool mounting plate 304 to drive the fourth.

0038In the illustrated exemplary embodiment, the articulated or rapid detachable joint 210 also includes an outer locking collar 260 that is slidably pivotally supported on the distal end 204 of the proximal outer tube portion 202. The outer locking collar 260 has four inwardly extending locks 262 that extend into the corresponding one of slot 254 of the proximal outer tube portion 202. The use of the rapid detachable joint 210 can be understood by referring to FIGS. 21-23. FIG. 21 shows the state of the proximal shaft portion 201 and the distal shaft portion 230 before being connected together. As can be seen in the drawing, the spring arm portions 223 and 227 of the proximal joint links 224 and 226, respectively, naturally warp outward in the radial direction. The locking collar 260 is moved to the most recent position on the proximal outer tube 202, where the lock 262 is located at the proximal end of slot 254 inside. When the clinician wants to attach the end effector 1000 to the proximal axis portion 201 of the surgical tool 100, the clinician aligns the distal axis portion 230 axially with the proximal axis portion 201, as shown in FIG. And connect and engage. As seen in the drawing, the distal magnet 510 is seated in the cavity 506 of the drive rod connector 502 and magnetically attached to the proximal magnet 504, thereby providing the distal drive rod segment 520. Connect to the proximal drive rod segment 592. This action operably connects the distal axial drive row assembly 528 to the proximal axial drive row assembly 496. In addition, as the shaft portions 201, 230 are joined together, the holding finger 544 has a locking opening in which the holding 546 formed on it is located at the distal end portion 381 of the proximal drive shaft segment 380. Bend inward until it enters section 383. When the retainer 546 is seated in their individual locking holes 383, the distal drive shaft segment 540 is coupled to the proximal drive shaft segment 380. Thus, such action operably connects the distal rotary drive row assembly 548 to the proximal rotary drive row assembly 387. Therefore, the distal connection
0039When the clinician wants to separate the end effector 1000 from the proximal axis portion 201 of the surgical tool 100, the clinician returns the third and fourth drive systems 430, 450 to their neutral position. The clinician may then slide the locking collar 260 proximally onto the proximal outer tube segment 202 to reach the starting position shown in FIG. When in that position, the spring arm portion of the proximal joint links 222, 226 disengages the toothed portion from the toothed portion of the distal joint links 242, 246. The clinician then applies an unlocking motion UL to the proximal end 517 of the unlocking tube 514 to distally "DD" the unlocking tube 514 and the unlocking collar 516 attached to it. You may move it with. As the unlock collar 516 moves distally, it urges the holding finger 544 to engage their individual holes 383 in the distal end portion 381 of the proximal drive shaft segment 380. Is removed and brought into contact with the tapered mounting portion 512 to remove the distal magnet 510 from being magnetically engaged with the proximal magnet 504.
0040Figures 22A, 23A, and 23B are similar to the rapid desorption joint 210 described above, except that an electromagnet 504'is used to connect the distal drive rod segment 520 to the proximal drive rod segment 492'. , An alternative coupling configuration or rapid detachment joint assembly 210'' is shown. As can be seen in these drawings, the proximal drive rod segment 492'is hollow to accommodate the conductor 505 extending from the power source of the robot system 10. The conductor 505 is wound around the iron piece 508. When the clinician engages the distal shaft portion 230 with the proximal shaft portion 201 as shown in FIG. 22A, the current passes through the conductor 505 in the first direction and thus the magnet as shown in FIG. 23A. The 504'may attract the magnet 510 and engage in connection. When the clinician wants to separate the end effector 1000 from the proximal axis portion 201 of the surgical tool 100, the clinician returns the third and fourth drive systems 430, 450 to their neutral position. The clinician may then slide the locking collar 260 proximally onto the proximal outer tube segment 202 to reach the starting position shown in FIG. 22A. When in that position, the spring arm portion of the proximal joint links 222, 226 disengages the toothed portion from the toothed portion of the distal joint links 242, 246. The clinician then applies an unlocking motion UL to the proximal end 517 of the unlocking tube 514 to distally "DD" the unlocking tube 514 and the unlocking collar 516 attached to it. You may move it with. In addition, the current may pass through the conductor 505 in the opposite direction to help the electromagnet 504'repel the magnet 510 and separate the shaft segment. As the clinician moves the unlock tube distally, the unlock collar 516 urges the holding finger 544 to those at the distal end portion 381 of the proximal drive shaft segment 380. The individual holes 383 are disengaged and brought into contact with the tapered mounting portion 512 to further separate the shaft segment.
0041The connection configuration or rapid separation joint assembly described above may provide many advantages. For example, such a configuration may use a single disengagement / engagement motion that cannot be left in a semi-engaged state. Such engagement movements can be used to operably connect several drive row assemblies at the same time, in which case at least some drive row assemblies are combined with the control movements provided by the other drive row assemblies. Provides different control movements. For example, some drive trains may be longitudinally shiftable to provide rotational control motion as well as axial control motion, and some may simply be rotational or axial control motion. I will provide a. Other drive row assemblies may provide push / pull motions to operate various end effector systems / components. A unique new locking collar configuration allows the distal drive row assemblies to be locked to or unlocked from their individual proximal drive row assemblies. Be secured. When locked together, all drive row assemblies are radially supported by a locking collar that prevents any disconnection.
0042The surgical tool 100 shown in FIGS. 5 and 11-16 collaborates with the third and fourth drive systems 430 and 450 to articulate the end effector 1000 around the longitudinal tool axis "LT". Includes 700 joint joints. The joint 700 includes a proximal socket tube 702 that is attached to the distal end 233 of the distal outer tube portion 231 and defines a proximal ball socket 704 therein. See Figure 25. The proximal ball member 706 is movably seated in the proximal ball socket 704. As seen in FIG. 25, the proximal ball member 706 has a central drive passage 708 that allows the distal drive shaft segment 540 to extend through. In addition, the proximal ball member 706 is contained in four articulated passages 710 that facilitate the passage of the distal cable segments 444, 445, 446, 447. As further seen in FIG. 25, the joint 700 further includes an intermediate joint tube segment 712 having an intermediate ball socket 714 formed therein. The intermediate ball socket 714 is configured to movably support the end effector ball 722 formed on the end effector connector tube 720. Distal cable segments 444, 445, 446, 447 extend through the cable passage 724 formed within the end effector ball 722 and have a protrusion 726 received within the corresponding passage 728 within the end effector ball 722. Attached there by. Other mounting configurations may be used to mount the distal cable segments 444, 445, 446, 447 to the end effector ball 722.
0043A unique new rotary support joint assembly, designated as 740 overall, is shown in Figures 26 and 27. The rotary support fitting assembly 740 shown includes a connector portion 1012 of an end effector drive housing 1010 that is approximately cylindrical in shape. The first annular raceway ring 1014 is formed around the cylindrical connector portion 1012. The rotary support fitting assembly 740 further comprises a distal socket portion 730 formed in the end effector connector tube 720, as shown in FIGS. 26 and 27. The distal socket portion 730 is sized relative to the cylindrical connector portion 1012 so that the connector portion 1012 can rotate freely within the socket portion 730. The second annular raceway ring 732 is formed on the inner wall 731 of the distal socket portion 730. A window 733 is provided through the distal socket 730 to communicate with the second annular track ring 732 inside. As also seen in FIGS. 26 and 27, the rotary support joint assembly 740 further includes a ring bearing 734. In various exemplary embodiments, the ring bearing 734 comprises a plastically deformable, substantially circular ring with a cut 735. The cut forms free ends 736, 737 in the ring bearing 734. As can be seen in FIG. 26, the ring-shaped bearing 734 has a substantially annular shape in its neutral, non-urging state.
0044To connect the surgical end effector 1000 (eg, the first part of the surgical instrument) to the joint 700 (eg, the second part of the surgical instrument), the cylindrical connector part 1012 is the distal socket part. Inserted into the 730, the second annular raceway ring 732 is approximately aligned with the first annular raceway ring 1014. One of the free ends 736, 737 of the link bearing is then inserted into the aligned annular raceway wheels 1014, 732 through a window 733 in the distal socket portion 730 of the end effector connector tube 720. To facilitate easy insertion, the window or opening 733 has a tapered surface 738 formed on it. See Figure 26. The ring-shaped bearing 734, by its nature, tends to rotate in place and form a circle or ring, so once installed it does not tend to recede through the window 733 and exit. Once the ring-shaped bearings 734 are inserted into the aligned annular raceway rings 1014, 732, the end effector connector tube 720 is rotatably secured to the connector portion 1012 of the end effector drive housing 1010. With this configuration, the end effector drive housing 1010 can rotate about the longitudinal tool axis LT-LT with respect to the end effector connector tube 720. The ring-shaped bearing 734 is the bearing surface on which the end effector drive housing 1010 then rotates. Some lateral load attempts to deform the ring bearing 734 supported and constrained by the two meshing drive wheels 1014, 732, preventing damage to the ring bearing 734. It will be appreciated that such a simple and effective fitting assembly with ring bearings 734 forms a very lubricious interface between the rotatable parts 1010, 730. During assembly, if one of the free ends 736, 737 is allowed to project out through the window 733 (see, eg, FIG. 27), the rotary support joint assembly 740 will provide a ring bearing member 732 through the window 733. Pull out It may be decomposed by. The rotary support fitting assembly 740 allows for easy assembly and manufacture, while facilitating the rotational operation of the end effector and providing its good support.
0045The joint 700 facilitates the joint joint of the end effector 1000 centered on the longitudinal tool axis LT. For example, when it is desirable to articulate the end effector 1000 in the first direction "FD" as shown in FIG. 5, the robot system 10 has a third drive spindle assembly 436 (FIGS. 11-13) first. Rotates in the direction of, thereby pulling the proximal cable end 434A and finally the distal cable segment 444 in the proximal direction "PD", the proximal cable end 434B and the distal cable segment 445. The third drive system 430 may be powered so that the end effector ball 722 is rotated in the socket 714. Similarly, because the end effector 1000 is articulated in the second direction "SD" opposite to the first direction FD, the robot system 10 has the third drive spindle assembly 436 rotated in the second direction, which By pulling the proximal cable end 434B and finally the distal cable segment 445 in the proximal direction "PD", the proximal cable end 434A and the distal cable segment 444 are released, thereby ending. The third drive system 430 may be powered to rotate the effector ball 722 within the socket 714. When it is desirable to articulate the end effector 1000 in a third direction "TD" as shown in FIG. 5, the robot system 10 has a fourth drive spindle assembly 456 rotating in the third direction. By pulling the proximal cable end 454A and finally the distal cable segment 446 in the proximal direction "PD", the proximal cable end 454A and the distal cable segment 447 are released, thereby ending. The fourth drive system 450 may be powered to rotate the effector ball 722 within the socket 714. Similarly, in order to joint the end effector 1000 in the fourth direction "FTH" opposite to the third direction TD, the robot system 10 has a fourth drive spindle.
0046The end effector embodiments shown in FIGS. 5 and 11-16 use rotational and longitudinal movements, which are transmitted for operation from the tool mounting portion 300 through an elongated shaft assembly. The drive shaft assembly used to transmit such rotational and longitudinal motions (eg, twisting, stretching, and compressive motions) to the end effector is to facilitate the end effector's articulation around the articulation joint. , Relatively flexible. 28 and 29 show an alternative drive shaft assembly 600 that may be used in connection with or in other embodiments shown in FIGS. 5 and 11-16. In the embodiment shown in FIG. 5 with a rapid detachable fitting 210, the proximal drive shaft segment 380 comprises a segment of drive shaft assembly 600 and the distal drive shaft segment 540 is similarly another segment of drive shaft assembly 600. To be equipped. The drive shaft assembly 600 includes a drive tube 602 in which a series of annular joint segments 604 are cut. In the illustrated embodiment, the drive tube 602 comprises a distal portion of the proximal drive shaft segment 380.
0047The drive tube 602 comprises a hollow metal tube (stainless steel, titanium, etc.) having a series of annular joint segments 604 formed therein. The annular joint segment 604 comprises, for example, a plurality of loosely meshing dovetail shapes 606 that are laser cut into the drive tube 602 to facilitate flexible movement between adjacent joint segments 604. See Figure 29. Such laser cutting of the tube material creates a flexible hollow drive tube that can be used for compression, stretching, and twisting. Such a configuration uses opposite cuts that are meshed with adjacent parts in the form of "puzzle pieces". These cuts are then replicated along the length of the array of hollow drive tubes, optionally "timed" or rotated to alter stretch or twist performance.
0048Figures 30-34 show alternative exemplary microscopic features with multiple laser cutting shapes 606', which are roughly similar to the loosely meshing opposing "T" shape and the T shape with a notch inside. An annular joint segment 604'is shown. The annular joint segments 604, 604'essentially include a plurality of microarticular joint torsion joints. That is, the respective joint segments 604 and 604'can transmit torque and facilitate relative joint joints between the respective annular joint segments. As shown in FIGS. 30 and 31, the joint segment 604D'at the distal end 603 of the drive tube 602 attaches to other drive components for articulating such as end effectors or parts of rapid desorption joints. The fitting segment 604P', which has a distal mounting collar portion 608D and is located at the proximal end 605 of the drive tube 602, facilitates mounting to other proximal drive components or parts of the rapid desorption joint. Has a proximal side mounting collar part 608P'.
0049The range of motion between the joints for each particular drive shaft assembly 600 can be increased by increasing the laser cutting interval. For example, an auxiliary restraint member 610 is used to ensure that the joint segment 604'remains connected together without significantly reducing the ability of the drive tube to articulate over the desired range of motion. In the embodiments shown in FIGS. 32 and 33, the auxiliary restraint member 610 comprises a spring 612 or other spirally wound member. In various exemplary embodiments, the distal end 614 of the spring 612 corresponds to the distal mounting collar portion 608D and is wound tighter than the central portion 616 of the spring 612. Similarly, the proximal end 618 of the spring 612 is wound tighter than the central portion 616 of the spring 612. In other embodiments, the restraint member 610 is placed on the drive tube 602 at the desired pitch, whereby the restraint member can screw, for example, an end effector and / or other threaded control components on the control system. It also functions as a flexible drive screw for engaging with. It will also be appreciated that the restraint members may be installed in such a way that they have a variable pitch that achieves the desired transmission of rotational control motion while rotating the drive shaft assembly. For example, variable pitch configurations of constraining members may be used to improve open / close and launch motions that would benefit from linear strokes different from the same rotational motion. In another embodiment, for example, the drive shaft assembly comprises a variable pitch thread on a hollow flexible drive shaft that can be pushed and pulled around a 90 degree bend. In yet another embodiment, the auxiliary restraint member comprises an elastomeric tube or coating 611 applied around the outer surface or periphery of the drive tube 602, as shown in FIG. 34A. In yet another embodiment, for example, the elastomeric tubing or coating 611'is installed in a hollow passage 613 formed within the drive tubing 602, as shown in FIG. 34B.
0050Such drive shaft configurations include composite torsional drive axles that allow for superior load transfer while facilitating a desired axial joint range. See, for example, Figures 34 and 34A-B. That is, these composite drive shaft assemblies allow for a large range of motion, while maintaining the possibility of transmitting twist in both directions and facilitating the transmission of twist and compression control motion through it. In addition, the hollow nature of such drive shaft configurations facilitates the passage of other control components through while providing improved tensile loads. For example, some other embodiments include a flexible internal cable that extends through the drive shaft assembly, which can assist in aligning the joint segments, while applying extensional motion through the drive shaft assembly. Ability is facilitated. Moreover, such drive shaft configurations are relatively easy to manufacture and assemble.
0051Figures 35-38 show segment 620 of the drive shaft assembly 600'. This embodiment includes fitting segments 622, 624 laser-cut from tube raw materials (eg, stainless steel, titanium, polymers, etc.). The joint segments 622, 624 both remain loosely attached because the cut 626 is radial and tapered to some extent. For example, each protruding portion 628 has a tapered outer peripheral portion 629 received within a socket 630 having a tapered inner wall portion. See, for example, Figures 36 and 38. Therefore, no assembly is required to attach the joint segments 622 and 624 together. As can be seen in the drawing, the joint segment 622 has opposed swivel protrusions 628 cut off on each end thereof that are swivelly accepted by the corresponding socket 630 formed in the adjacent joint segment 624. ..
0052Figures 35-38 show a small segment of drive shaft assembly 600'. Those skilled in the art will recognize that the protrusions / sockets may be cut through the entire length of the drive shaft assembly. That is, the joint segment 624 may have opposed sockets 630 cut to facilitate linking with the adjacent joint segment 622 to complete the length of the drive shaft assembly 600'. In addition, the joint segment 624 has an angled end 632 cut to facilitate joint joint of the joint segment 624 to the joint segment 622, as shown in FIGS. 37 and 38. In the illustrated embodiment, each protrusion 628 has a joint stop portion 634 adapted to contact the corresponding joint stopper 636 formed on the joint segment 622. See Figures 37 and 38. Other embodiments, which may otherwise be identical to segment 620, do not include a joint stop portion 634 and a stopper 636.
0053As mentioned above, the range of motion between the joints for each particular drive shaft assembly can be increased by increasing the laser cutting interval. In such embodiments, the elastomeric sleeves or coatings 640 ensure that the joint segments 622, 624 remain connected together without significantly reducing the ability of the drive tube to articulate over the desired range of motion. Auxiliary restraint member in the form of is used. Other embodiments use other modes of restraint members disclosed herein and their equivalent structures. As seen in FIG. 35, the joint segments 622, 624 can swivel around a swivel axis "PA-PA" as defined by the swivel protrusion 628 and the corresponding socket 630. To obtain an expanded joint range, the drive shaft assembly 600'may rotate about the tool axis TL-TL while turning around the swivel axis PA-PA.
0054Figures 39-44 show segment 640 of another drive shaft assembly 600''. The drive shaft assembly 600'' comprises a multi-segment drive system that includes a plurality of interconnected joint segments 642 forming a flexible hollow drive tube 602''. The fitting segment 642 includes a ball connector portion 644 and a socket portion 648. Each fitting segment 642 is made, for example, by metal injection molding "MIM" and may be made from 17-4, 17-7, 420 stainless steel. Other embodiments may be machined from 300 or 400 series stainless steel, 6065 or 7071 aluminum or titanium. Still other embodiments can be molded from, for example, plastic-filled or unfilled nylon, Ultem, ABS, polycarbonate, or polyethylene. As can be seen in the drawing, the ball connector 644 has a hexagonal shape. That is, the ball connector 644 has six arched surfaces 646 formed on it and is rotatably adapted to a similarly shaped socket 650. Each socket 650 has a hexagonal outer portion 652 formed from six flat surfaces 654 and a radially shaped inner portion 656. See Figure 42. Each fitting segment 642 may be configured such that the socket portion of the last fitting segment forming the distal and proximal ends of the drive shaft assembly 600 operably meshes with the corresponding control component. Except for, it is structurally the same. Each ball connector 644 has a hollow passage 645 in which a hollow passage 603 through the hollow flexible drive tube 602'' is jointly formed.
0055As seen in FIGS. 43 and 44, the interconnected fitting segment 642 is housed within a restraint member 660, including, for example, a tube or sleeve made of a flexible polymeric material. FIG. 45 shows a flexible inner core member 662 extending through an interconnected joint segment 642. The inner core member 662 comprises a solid member made of a polymeric material or a hollow tube or sleeve made of a flexible polymeric material. FIG. 46 shows another embodiment in which both the restraint member 660 and the inner core member 662 are used.
0056The drive shaft assembly 600'' facilitates the transmission of rotational and translational motion through various radial joints. The hollow nature of the drive shaft assembly 600'' provides room for additional control components or tension elements (eg, flexible cables) that facilitate the transmission of tension and compressive loads. However, in other embodiments, the fitting segment 624 does not provide a hollow passage through the drive shaft assembly. In such an embodiment, for example, the ball connector is solid. The rotational motion is translated through the edges of the hexagonal surface. Tighter tolerances may allow for larger load capacities. Cables or other pulling elements through the centerline of the drive shaft assembly 600'' can be used to rotate, bend, push, and pull the entire drive shaft assembly 600'' without limiting the range of motion. .. For example, the drive shaft assembly 600'' may form a bow-shaped drive path, a straight drive path, a meander-shaped drive path, and the like.
00575 and 47-54 show one surgical end effector 1000 that may be effectively used with the robot system 10. The end effector 1000 comprises an end cutter 1002 having a first grip 1004 and a second grip 1006 that is selectively movable relative to the first grip 1004. In the embodiments shown in FIGS. 5 and 47-54, the first gripper 1004 comprises a support member 1019 in the form of an elongated channel 1020 configured to operably support the staple cartridge 1030 inside. The second gripper 1006 comprises an anvil assembly 1100. As seen in FIGS. 47, 49, 53, and 55, the anvil assembly 1100 comprises an anvil body 1102 having a staple forming surface 1104 on it. The anvil body 1102 has a passage 1106 adapted to align with the mounting holes 1022 of the elongated channel 1020. A swivel or trunnion pin (not shown) is inserted through holes 1022 and passage 1104 to swivelly connect the anvil 1100 to an elongated channel 1020. With this configuration, the anvil assembly 1100 is placed in an open position (FIGS. 47 to 50) where the staple forming surface 1104 is separated from the cartridge deck 1044 of the staple cartridge 1040, and the staple forming surface 1104 of the anvil body 1102 is relative to the cartridge deck 1042. It is possible to selectably turn around the closed axis "CA-CA" that is almost orthogonal to the longitudinal tool axis "LT-LT" with the closed positions (Figs. 51 to 54) that are facing each other. it can.
0058The embodiments of FIGS. 5 and 47-54 use a closure assembly 1110 configured to accept opening and closing movements from a fifth drive system 470. The fifth drive system 470 serves to advance and retract the drive rod assembly 490 in the axial direction. As mentioned above, the drive rod assembly 490 includes a proximal drive rod segment 492 that operably interfaces with and accepts axial control motion from the drive solenoid 474. The proximal drive rod segment 492 is connected to the distal drive rod segment 520 through the drive rod connector 502. The distal drive rod segment 520 is somewhat acceptable to facilitate joint jointing of the end effector 1000 centered on the joint 700 and also to facilitate axial transmission of closing and opening movements through it. It is flexible. For example, the distal drive rod segment 520 may include a titanium, stainless spring steel, or nitinol cable or laminated structure.
0059The closure assembly 1110 includes a closure link mechanism 1112 that is swivelly attached to an elongated channel 1020. As seen in FIGS. 48, 51, and 52, the closed link mechanism 1112 has an opening 1114 through which the distal end 524 of the distal drive rod segment 520 extends. A ball 526 or other component is attached to the distal drive rod segment 520, whereby the distal end 524 of the distal drive rod segment 520 is attached to the closure linkage 1112. The closure assembly 1110 further includes a pair of cam plates 1120 rotatably mounted on the sides of the elongated channel 1020. One cam plate 1120 is rotatably supported on one side surface of the elongated channel 1020 and the other cam plate 1120 is rotatably supported on the other side surface of the elongated channel 1020. See Figure 60. A pair of swivel links 1122 are mounted between their respective cam plates 1120 and the closing link mechanism 1112. Therefore, the swivel movement of the closed link mechanism 1112 by the drive rod assembly 490 results in the rotation of the cam plate 1120. Each cam plate 1120 further has an actuator pin 1124 projecting from the cam plate that is slidably accommodated in the corresponding cam slot 1108 of the anvil body 1102.
0060Next, the operation of the second gripper 1006 or the anvil assembly 1100 will be described. Figures 47-50 show the anvil assembly 1100 in the open position. After the end effector 1000 has been positioned relative to the tissue to be cut and stapled, the robot controller 12 may initiate the drive solenoid 474 in the first or distal "DD" direction, thereby ultimately. , A distal movement of the drive yoke 472 is provided to move the drive rod assembly 490 in the distal "DD" direction. This movement of the drive rod assembly 490 results in a distal movement of the distal drive rod segment 520, which causes the closure linkage 1112 to swivel from the open position to the closed position (FIGS. 51-54). This movement of the closed link mechanism 1112 causes the cam plate 1120 to rotate in the "CCW" direction. As the cam plate rotates in the "CCW" direction, the interaction between the actuator pins 1124 and their individual cam slots 1108 causes the anvil assembly 1100 to swivel and close on the target tissue. To release the target tissue, the drive solenoid 474 is activated to pull the drive rod assembly 490 in the proximal "PD", which results in a reverse swivel movement of the closed link mechanism 1112 to the open position. Eventually, the anvil assembly 1100 turns and returns to the open position.
0061Figures 55-59 show another closure system 670 for adding opening and closing movements to the anvil 1100. As seen in FIG. 56, for example, the closure system 670 includes a first mounting block or member 672 that rotatably supports the first closure rod segment 680. The first closed rod segment 680 has a substantially semicircular cross-sectional shape. The proximal end 682 of the first closed rod segment 680 has a first ball connector 684 rotatably supported within the first mounting socket 673 formed in the mounting block 672. To facilitate the joint of the end effector 1000 with the joint 700, the first closed rod segment 680 also has a first serrated portion 686 that matches the joint 700 as shown in FIGS. 58 and 59. Have. The closure system 670 further includes a second mounting block or member 674 that rotatably supports the second closure rod segment 690. The second closed rod segment 690 has a substantially semicircular cross-sectional shape. The proximal end 692 of the second closed rod segment 690 has a second ball connector 694 rotatably supported within the second mounting socket 675 formed in the second mounting block 674. .. To facilitate the joint of the end effector 1000 with the joint 700, the second closed rod segment 690 also has a second serrated portion 696 that matches the joint 700 as shown in FIGS. 58 and 59. Have.
0062As also seen in FIG. 56, the closure system 670 further has a first swivel link 676 attached to the distal end 682 of the first closure rod segment 680. A first swivel link 676 is formed on a link configured to be rotatably supported within a first socket 683 formed at the distal end 682 of the first closed rod segment 680. It has one swivel protrusion 677. Such a configuration allows the first swivel link 676 to rotate relative to the first closed rod segment 680. Similarly, the second swivel link 678 is attached to its distal end 691 so that it can rotate relative to the second closed rod segment 690. The second swivel link 678 extends through the opening of the first swivel protrusion 677 and is rotatably supported within the second socket 692 at the distal end 1691 of the second closure rod segment 690. It has a second swivel protrusion 1679 formed on the link as configured. In addition, as seen in FIG. 56, the first and second swivel links 676,678 are on a second swivel link 678 that is slidably accepted into slot 717 of the first swivel link 676. Key 716 locks them so that they can move to each other. In at least one embodiment, a first swivel link 676 is attached to each cam plate 1120 by a first link mechanism arm 687 and a second swivel link 678 is attached to a cam plate 1120 by a second link mechanism arm 688. Attached to each.
0063In the illustrated embodiment, the closure system 670 is actuated by a drive solenoid 474. The drive solenoid 474 is configured to operably interface with one of the first and second mounting blocks 672, 674 and to apply axial closing and opening motions to it. As seen in FIGS. 56-59, such drive configurations are movably attached to the first mounting block 672 by pins 685 extending into slot 696 of the first swivel link and gear assembly 695. A first swivel link and gear assembly 695 may further be provided. Similarly, the second swivel link and gear assembly 697 is movably attached to the second mounting block 674 by a pin 685 extending into slot 698 of the second swivel link and gear assembly 697. The first swivel link and gear assembly 695 has a first bevel gear 699A rotatably attached to it, and the second swivel link and gear assembly 697 has a second bevel gear rotatably attached to it. It has a gear 699B. Both the first and second bevel gears 699A and 699B are mounted in mesh with the play gear 689 rotatably mounted on the tool mounting plate 302. See Figure 59A. Therefore, when the first mounting block 672 is advanced in the distal direction "DD" and thereby the first closed rod segment 680 and the first swivel link 676 are also moved in the distal direction DD, the bevel gears 689, 699A. , 699B provides proximal "PD" movement of the second closure rod 690 and the second swivel link 678. Similarly, when the first mounting block 672 is advanced in the proximal direction "PD" and thereby the first closed rod segment 680 and the first swivel link 676 are also moved in the proximal direction PD, the bevel gear 689, The 699A, 699B result in distal "DD" movement of the second closure rod 690 and the second swivel link 678.
0064FIG. 58 shows the anvil 1100 in the open position. As can be seen in the drawing, the first closing rod 680 is slightly proximal to the second closing rod 690. To close the anvil, the drive solenoid 474 is powered to advance the first closing rod 680 axially in the distal "DD" direction. By this action, the first swivel link 676 and the first link mechanism arm 687 rotate the cam plate 1120 in the counterclockwise "CCW" direction as shown in FIG. 59. Such action also results in a proximal movement of the second closing rod 690, which also causes the second swivel link 678 and the second link mechanism arm 688 to pull the cam plate 1120 in the counterclockwise "CCW" direction. To open the anvil, the drive solenoid 474 applies axial control motion to the first mounting block 672 to return the first and second control rod segments 680, 690 to the positions shown in FIG. ..
0065Embodiment 1000 of the end effector shown in FIG. 60 includes a drive configuration generally designated as 748 that facilitates the selective addition of rotational control motion to the end effector 1000. The end effector 1000 includes a launching member 1200 that is screwed on the instrument drive shaft 1300. As seen in FIG. 61, the appliance drive shaft 1300 has a bearing segment 1304 rotatably supported within the bearing sleeve 1011 formed therein. The instrument drive shaft 1300 operably interfaces with the elongated channel 1020 and operably meshes with a rotation transmission device designated as 750 overall, operably supported by a portion of the elongated shaft assembly 200. It has an instrument drive gear 1302. In one exemplary embodiment, the rotation transmission device 750 includes a differential interlocking assembly 760. As seen in FIGS. 64 and 65, the differential interlocking assembly 760 is configured to rotate selectively with respect to and with the end effector housing 1010, the differential housing 762. Including.
0066The distal drive shaft segment 540 is attached to the sun gear shaft 752 to which the sun gear 754 is mounted. Therefore, when the distal drive shaft segment 540 is rotated, the sun gear 754 is rotated. The sun gear 754 also moves axially along with the distal drive shaft segment 540. The differential interlocking assembly 760 further includes a plurality of planetary gears 764 rotatably attached to the differential housing 762. In at least one embodiment, for example, three planetary gears 764 are used. Each planetary gear 764 meshes with a first end effector ring gear 1016 formed within the end effector drive housing 1010. In the illustrated exemplary embodiment shown in FIG. 60, the end effector drive housing 1010 has a pair of opposing mounting projections 1018 (only one mounting projection 1018 is seen in FIG. 60) close to the elongated channel 1020. It is non-rotatably attached to the elongated channel 1020 by entering the corresponding mounting slot 1024 formed at position 1021 (only one mounting slot 1024 is seen in FIG. 60). Other methods may be used in which the end effector drive housing 1010 is immobilely attached to the elongated channel 1020, or the end effector drive housing 1010 may be formed integrally with the elongated channel 1020. Therefore, the rotation of the end effector drive housing 1010 results in the rotation of the elongated channel 1020 of the end effector 1000.
0067In the embodiments shown in FIGS. 61-65, the differential interlocking assembly 760 further includes a second ring gear 766 formed within the differential housing 762 for meshing engagement with the sun gear 754. The differential interlocking assembly 760 also includes a third ring gear 768 formed within a differential housing 762 that meshes with the instrument drive gear 1302. Rotation of the differential housing 762 within the end effector drive housing 1010 ultimately results in rotation of the instrument drive gear 1302 and the instrument drive shaft 1300 attached to it.
0068When a clinician wants to rotate the end effector 1000 around the longitudinal tool axis LT-LT on the distal side of the joint 700 to position the end effector in the desired orientation with respect to the target tissue, the robot controller 12 Triggered the shifter solenoid 394 to axially move the proximal drive shaft segment 380 so that the sun gear 754 moves to the "first axial" position shown in Figures 65, 67, and 70. You may move it. As described in detail above, the distal drive shaft segment 540 is operably connected to the proximal drive shaft segment 380 by a rapid desorption joint 210. Therefore, axial movement of the proximal drive shaft segment 380 may result in axial movement of the drive shaft segment 540 and the sun gear 752 and the sun gear 754. Further, as described above, the shift system 390 controls the axial movement of the proximal drive shaft segment 380. In the first axial position, the sun gear 754 meshes with the planetary gear 764 and the second ring gear 766, which causes the planetary gear 764 and the differential housing 762 to rotate until the sun gear 754 rotates. To do.
0069The rotation of the proximal drive shaft segment 380 is controlled by a second drive system 370. The rotation of the proximal drive shaft segment 380 results in the rotation of the distal drive shaft segment 540, the sun gear shaft 752, and the sun gear 754. This rotation of the differential housing 762 and the planetary gear 764 as a unit overcomes the first friction amount F1 between the end effector drive housing 1010 and the distal socket portion 730 of the intermediate joint tube 712. Rotational motion is applied to the end effector drive housing 1010, which is large enough to allow the end effector drive housing 1010 and the end effector 1000 attached to it to be longitudinally relative to the distal socket tube 730. Rotate around the tool axis "LT-LT". Therefore, when in this position, the end effector drive housing 1010, the differential housing 762, and the planetary gear 764 all rotate together as a unit. Since the instrument shaft 1300 is supported by a bearing sleeve 1011 in the end effector drive housing, the instrument shaft 1300 also rotates with the end effector drive housing 1010. See Figure 61. Therefore, rotation of the end effector drive housing 1010 and end effector 1000 does not lead to relative rotation of the instrument drive shaft 1300, which would result in displacement of the launching member 1200. In the illustrated exemplary embodiment, such rotation of the end effector 1000 on the distal side of the articulation 700 does not rotate the entire elongated shaft assembly 200.
0070When it is desirable to apply a rotational drive motion to the instrument drive shaft 1300 to drive the launch member 1200 in the end effector 1000, the sun gear 754 is shown in FIGS. 61, 62, 64, and 66, as shown in FIGS. 61, 62, 64, and 66. Positioned in the "second axial direction" position in the axial direction, the second ring gear 766 is engaged and disengaged, while the planetary gear 764 is meshed and engaged. Therefore, when it is desirable to rotate the appliance drive shaft 1300, the robot controller 12 activates the shifter solenoid 394 to axially position the sun gear 754 to mesh and engage with the planetary gear 764. When in its second axial or "launch position", the sun gear 754 simply meshes and engages the planetary gear 764.
0071The rotation of the proximal drive shaft segment 380 may be controlled by a second drive system 370. The rotation of the proximal drive shaft segment 380 results in the rotation of the distal drive shaft segment 540, the sun gear shaft 752, and the sun gear 754. When the sun gear 754 is rotated in the first launch direction, the planetary gear 764 also rotates. As the planetary gear 764 rotates, so does the differential housing 762. Since the instrument drive gear 1302 meshes with the third ring gear 768, the rotation of the differential housing 762 causes the instrument shaft 1300 to rotate. Since there is a friction amount F1 between the end effector drive housing 1010 and the distal socket portion 730 of the intermediate joint joint tube 712, even if the planetary gear 764 rotates, the end effector housing 1010 will be in the intermediate joint joint tube 712. On the other hand, it does not rotate. Therefore, the rotation of the drive shaft assembly results in the rotation of the instrument drive shaft 1300 without rotating the entire end effector 1000.
0072Such a unique novel rotation transmission device 750 comprises a single drive system capable of selectively rotating the end effector 1000 or launching the launch member 1200, depending on the axial position of the rotation drive shaft. .. One advantage that can be provided by such a configuration is that it simplifies the drive unit that must cross the joint 700. Also, since the central drive device translates to the base of the elongated channel 1020, the instrument drive shaft 1300 can be present under the staple cartridge 1040 to drive the launch member 1200. The ability of the end effector to rotate distal to the joint can significantly improve the ability to position the end effector with respect to the target tissue.
0073As mentioned above, when the drive shaft assembly is positioned in the first axial position, even if the rotation of the drive shaft assembly results in rotation of the entire end effector 1000 on the distal side of the joint 700. Good. When the drive shaft assembly is positioned in the second axial position (distal side of the first axis in one embodiment), the rotation of the drive shaft assembly results in the rotation of the appliance drive shaft 1300. You may.
0074Embodiments of the rotation transmission device shown in FIGS. 64 and 65 include a differential fixation system 780 configured to hold the drive shaft assembly in the first and second axial positions. As seen in FIGS. 64 and 65, the differential fixation system 780 has a first holding formation 756 in the sun gear shaft 752 corresponding to the first axial position of the drive shaft assembly and a first of the drive shaft assembly. It comprises a second holding formation 758 in the sun gear shaft 752 corresponding to the axial position of 2. In the illustrated exemplary embodiment, the first holding formation comprises a first radial locking groove 757 within the first sun gear shaft 752 and the second holding formation 758 is a second. It comprises a second radial locking groove 759 formed within the sun gear shaft 752. The first and second locking grooves 757, 759 were adapted to hold and engage the locking grooves 757, 759, respectively, when the drive shaft assembly was in the first and second axial positions. Cooperate with at least one spring-loaded locking member 784. The locking member 784 has a tapered tip 786 and is movably supported within the differential housing 762. The radial corrugated spring 782 may be used to apply an urging force to the locking member 784, as shown in FIG. As the drive shaft assembly moves axially to the first position, the locking member 784 fits in and engages with the first radial locking groove 7576. See Figure 65. As the drive shaft assembly moves axially to the second position, the locking member 74 fits in and engages the second radial locking groove 759. See Figure 64. In an alternative embodiment, the first and second holding formations may include, for example, a recess corresponding to each of the locking members 784. Also, in alternative embodiments where the drive shaft assembly can be axially positioned in more than two axial positions, additional holding formations corresponding to each of those axial positions may be used.
0075Figures 70 and 71 show an alternative differential fixation system 790 configured to ensure that the drive shaft assembly is locked to one of a plurality of predetermined axial positions. The differential fixation system 790 unintentionally positions the drive shaft assembly in one of the first and second axial positions and in another axial position where the drive system cannot operate properly. It is configured to ensure that it is not done. In the embodiment shown in FIGS. 70 and 71, the differential fixation system 790 includes a plurality of locking springs 792 attached to the drive shaft assembly. Each locking spring 792 is locked by a first and second locking valley separated by a pointed apex portion 798. Valley) Formed with 794 and 796. The locking spring 792 is arranged to cooperate with a pointed locking member 763 formed on the differential housing 762. Therefore, when the pointed locking member 763 is seated in the first locking valley 794, the drive shaft assembly is held in the first axial position and the pointed locking member 763 is in the second locking valley. When seated in section 796, the drive shaft assembly is held in the second axial position. Due to the pointed apex 798 between the first and second locking valleys 794,796, the drive shaft assembly is in one of the first and second axial positions and the axial direction between those two axial positions. It is guaranteed not to get caught in the position. If an additional axial position is desired, the locking spring may be provided with an additional locking valley corresponding to the desired axial position.
0076With reference to FIGS. 60, 72, and 73, the thrust bearing 1030 is supported within the cradle 1026 of the elongated channel 1020. The distal end portion 1306 of the instrument drive shaft 1300 is rotatably received within the thrust bearing 1030 and projects through it. The retaining collar 1032 is pinned or otherwise secured to the distal end 1030, as shown in FIG. 73, to complete the installation. Using the thrust bearing 1030 in this way may allow it to "pull" from start to end within the elongated channel 1020 when launching the launch member 1200. Such a configuration may minimize the risk of buckling of the instrument drive shaft 1300 under high load conditions. The unique new mounting configuration and placement of the thrust bearing 1030 results in a seating load that increases with the anvil load, which further increases the stability of the end effector. Such a mounting configuration may essentially assist in arranging the instrument drive shaft 1300 in the extended state during the high load firing cycle. This may avoid the need for the gears of the drive system to rotate the instrument drive shaft 1300 and resist buckling of the shaft 1300. The use of retaining collar 1032 can also simplify the manufacture and assembly of this configuration. The launch member 1200 is configured to engage the anvil and hold the anvil at a desired distance from the cartridge deck as the launch member 1200 is driven from the start position to the end position. For example, in this configuration, as the assembly of the launching member 1200 moves the elongated channel 1020 distally, the length of part of the anvil that resembles a cantilever beam becomes shorter and stiffer, thereby causing the elongated channel 1020. The magnitude of the downward load that occurs at the distal end increases, further increasing the seating load of the bearing.
0077One of the advantages of utilizing rotational drive members for launching, closing, rotating, etc. is to use the advanced mechanical advantages of the drive shaft to adapt to the high loads required to accomplish those tasks of the instrument. It may include what you can do. However, when using such a rotary drive system, to avoid catastrophic failure or damage to the drive screws and other instrument components if the drive shaft and movable end effector components are driven too distally. , It may be desirable to track the number of revolutions at which the drive shaft is driven. Therefore, some systems, including rotary drive shafts, have traditionally used encoders that track the rotation of motors or sensors that monitor the axial position of movable components. The use of encoders and / or sensors requires additional wiring, electronics, and processing power to accommodate such systems, which can lead to increased equipment costs. Also, it can be somewhat difficult to predict the reliability of a system, which depends on the software and processor.
0078FIGS. 74-76 show a mechanical stroke limiting system 1310 that limits the linear stroke of the launching member 1200 as it is driven from the start position to the ending position. The stroke limiting system 1300 uses the instrument drive shaft 1300'where the thread 1308 on the instrument drive shaft 1300' does not extend to the distal end 1306 of the drive shaft 1300'. For example, as seen in FIGS. 74-76, the appliance drive shaft 1300'includes unthreaded compartment 1309. Since the launch member 1200 has a body portion 1202 with a series of female threads 1204 adapted to screwably interface with threads 1308 on the instrument drive shaft 1300', the instrument drive shaft 1300'is the first. When rotated in the firing direction, the launching member 1200 is driven in the distal direction "DD" until it contacts the unthreaded compartment 1309, at which point the launching member 1200 stops advancing in the distal direction. That is, the launching member 1200 advances distally until the female screw 1204 of the launching member 1200 disengages the thread 1308 of the instrument drive shaft 1300'. Further rotation of the instrument drive shaft 1300'in the first direction does not cause the launcher 1200 to move further distally. See, for example, Figure 75.
0079An exemplary mechanical stroke limiting system 1310 illustrated provides that when the launch member 1200 is advanced to the distal end of its stroke (ie, even if the instrument drive shaft rotates in the first rotational direction, the launch member Further includes a distal urging member 1312 configured to contact the launching member 1200 (which does not advance further distally). In the embodiments shown in FIGS. 74-76, for example, the urging member 1312 comprises a leaf spring 1314 positioned within an elongated channel 1020 as shown. FIG. 74 shows the leaf spring 1314 before the launching member 1200 comes into contact, and FIG. 75 shows the leaf spring 1314 in the compressed state after the launching member 1200 comes into contact. When in that position, the leaf spring 1314 urges the launcher 1200 in the proximal direction "PD" and when the appliance drive shaft 1300'is rotated in the second withdrawal direction, the female screw 1204 of the launcher 1200. Helps to allow the instrument drive shaft 1300'to be re-engaged. When the instrument drive shaft 1300'is rotated in the second withdrawal direction, the launching member 1200 is withdrawn in the proximal direction. See Figure 76.
0080Figures 77-80 show another stroke limiting system 1310'. The stroke limiting system 1310'uses a two-part instrument drive shaft 1300''. In at least one form, for example, the instrument drive shaft 1300'' has a proximal instrument drive shaft segment 1320 with a socket 1324 at the distal end 1322 and a distal drive with a protrusion 1334 protruding from the proximal end 1332. Includes axis segment 1330 and. The protrusion 1334 is sized and shaped to be accommodated within the socket 1324, whereby the thread 1326 on the proximal drive shaft segment 1320 collaborates with the thread 1336 on the distal drive shaft segment 1330. And form one continuous drive thread 1340. As seen in FIGS. 77, 79, and 90, the distal end 1338 of the distal drive shaft segment 1330 extends through a thrust bearing 1032 movably supported by the distal end 1023 of the elongated channel 1020. To do. That is, the thrust bearing 1032 is axially movable within the elongated channel 1020. The distal urging member 1342 is supported within the elongated channel 1020 so as to contact the thrust bearing 1032. FIG. 78 shows a launching member 1200 driven in the distal direction "DD" when the instrument drive shaft 1300'' is driven in the first rotational direction. FIG. 79 shows the launching member 1200 at the distal end of the stroke. Further rotation of the appliance drive shaft 1300'' in the first rotation direction causes the thrust bearing 1032 to compress the urging member 1342 and slip the distal shaft segment 1330 if the proximal segment 1320 continues to rotate. It becomes possible to make it. Such slipping between the proximal and distal instrument drive shaft segments 1320, 1330 prevents the launching member 1200 from advancing further distally and ultimately damaging the instrument. However, after the first rotational movement is interrupted, the urging member 1342 helps to urge the distal axis segment 1320 in the proximal direction, whereby the protrusion 1334 is seated in the socket 1324. After that, the instrument shaft 1300
0081FIG. 81 shows another stroke limiting system 1310''. In this embodiment, the appliance drive shaft 1300 has a protrusion 1350 formed on it, the protrusion of which is a bearing segment on which the appliance drive gear 1302 is formed or otherwise mounted. Size and shape are determined to fit within socket 1352 of 1304. Figures 81A and 81B show different protrusions 1350'(FIG. 81A) and 1350'' (FIG. 81B) configured to disengage the corresponding sockets 1352'and 1352'', respectively. The leaf spring 1314 is positioned so that the launch member 1200 comes into contact when the launch member 1200 reaches the end of its stroke. Further rotation of the instrument drive shaft 1300 causes the protrusions 1350, 1350', 1350'' to slide out of the sockets 1352, 1352', 1352'', respectively, which prevents the instrument shaft 1300 from rotating any further. Once no rotational motion is applied to the fixture drive shaft 1300, the leaf spring 1314 applies urging motion to the launching member 1200 and finally attaches the fixture drive shaft 1300 in the proximal direction "PD". Force the protrusion 1350 to sit in the socket 1352. As the instrument drive shaft 1300 rotates in the second rotation direction, the launching member 1200 is retracted to the starting position in the proximal direction "PD". Once the launching member 1200 has returned to the starting position, the anvil 1100 may then be opened.
0082In the illustrated exemplary embodiment, the launching member 1200 is configured to engage the anvil 1100 as it drives the launching member 1200 distally through an end effector, actively separating the anvil from the staple cartridge. It is ensured that closed staples are properly formed, especially when an incompatible amount of tissue is tightened. Other forms of launching members that are configured to engage anvils and are spaced apart from staple cartridges or elongated channels and may be used in this embodiment or other embodiments are described by reference in their entire disclosure. US Pat. No. 6,978,921, title of invention "Surgical Stapling Instrument Incorporating an E-beam Firing," incorporated herein. It is disclosed in "Mechanism". As seen in FIGS. 82 and 83, the body portion 1202 of the launch member 1206 includes a foot portion 1206 that upwardly engages the channel slot 1028 within the elongated channel 1020. See Figure 60. Similarly, the knife body includes a pair of laterally projecting upper fins 1208. When fired with the anvil 1100 closed, the upper fins 1208 advance distally within the longitudinal anvil slot 1103 extending distally through the anvil 1100. If the anvil 1100 has a slight upward deflection, it will be overcome by the downward force exerted by the upper fins 1208.
0083Broadly, the load required to close and advance the launch member, i.e. to "launch" the launch member, can exceed 90.7 kg (200 lbs). However, the requirement for such forces may require that the female thread 1204 of the launching member be provided with a relatively fine thread in the form of a power-type thread, such as an acme thread. In addition, at least 5-15 threads of the launching member must be threaded to adequately support the upper fins 1208 to avoid being connected when the launching member 1200 is driven distally through the end effector. It may be desirable to engage the threads on the instrument drive shaft at any given time. However, conventional manufacturing methods do not allow the launch member body 1202 to have sufficient threads with sufficient thread depth within an opening 0.2 cm to 0.38 cm (0.08 inches to 0.150 inches) in diameter. It may not be suitable.
0084Figures 82-84 show the launcher 1200'that can address at least some of the above issues. As seen in those drawings, the body portion 1202'of the launcher has a hollow shaft socket 1210 extending through it, sized to accommodate the instrument shaft inside. The female thread of this embodiment is formed by a series of rods 1214 extending in the transverse direction through the holes 1212 of the shaft socket 1210, as shown. As can be seen in FIG. 84, the pin 1214 rides on a small diameter pitch of threads 1308 on the instrument drive shaft 1300.
0085FIG. 85 shows another launching member 1200'' that can also address at least some of the manufacturing challenges mentioned above. As can be seen in the drawing, the body portion 1202'' of the launching member 100'' has a hollow shaft socket 1210 extending through it, sized to accommodate the instrument shaft inside. As shown, a pair of windows 1216 are formed on the body portion 1202''. The female thread 1220 of this embodiment is formed on a plug 1218 that is inserted into the window 1216 and attached inside by welding, adhesive, or the like. Figures 86 and 87 show another launch member 1200'' where access to the socket 1210 is obtained through access windows 1230A, 1230B formed in the body portion 1202''. For example, a pair of access windows 1230A can be provided through one side of the socket portion 1210 to allow the female thread segment 1232 to be formed in the opposite wall of the socket 1210. Another access window 1230B is provided through the opposite side of the socket portion 1210, whereby the female thread segment 1234 can be formed on the opposite wall between the female thread segments 1232. Thread segments 1232, 1234 work together to screw thread 1308 on the instrument drive shaft 1300.
0086The end effector 1000 supports the staple cartridge 1040 so that it can be released inside. See Figure 60. The staple cartridge 1040 includes a cartridge body 1042 configured to be operably seated with an elongated channel 1020. The cartridge body 1042 has an elongated slot 1046 inside that houses the launching member 1200. The cartridge body 1042 further defines an upper surface referred to herein as the cartridge deck 1044. In addition, two lines of staggered staple apertures 1048 are provided on each side of the elongated slot 104. The staple aperture 1048 operably supports a corresponding staple driver 1050 on which one or two surgical staples (not shown) are supported. Various such staple driver configurations are known and may be used without departing from the spirit and scope of the various exemplary embodiments of the invention.
0087The launch member embodiment also uses a wedge thread assembly 1250 that is in driveable contact with a staple driver operably supported within the staple cartridge 1040. As seen in FIG. 60, the wedge thread assembly 1250 contains at least two wedges 1252 oriented to driveably contact a line of staple drivers operably supported within the staple cartridge 1040. When the launch member 1200 is driven distally, the wedge thread assembly 1250 moves with the launch member 1220, and the wedge 1252 above it pushes the driver 1050 toward the closed anvil 1100. When the driver 1050 is driven upwards, the surgical staples supported on it are delivered from their individual apertures 1048 and come into contact with the staple forming surfaces 1104 of the closed anvil 1100.
0088The various exemplary end effector embodiments disclosed herein also include when the cartridge is absent and the cartridge is not properly seated in the end effector, and / or the used cartridge is in the end effector. A unique new launch lockout configuration may be used to prevent the clinician from inadvertently advancing or "launching" the launching member when left in place. For example, as discussed in more detail below, the launch lockout configuration interacts with the instrument drive shaft 1300 and / or the launch member 1200 and when one of the above conditions is present, the launch member 1200 You may prevent inadvertent advancement.
0089In the illustrated exemplary embodiment, the launch member 1200 is properly aligned with, for example, the elongated slot 1046 of the cartridge body 1042 (FIG. 60), the channel slot 1028 of the elongated channel 1020, and the anvil slot 1103 of the anvil 1100. If the instrument drive shaft 1300 rotates in the first rotation or "launch" direction, the launch member 1200 is driven distally through the staple cartridge 1040. Primarily with reference to FIG. 90, the elongated slot 1046, channel slot 1028, and / or anvil slot 1103, for example, during the launch stroke, as the launch member 1200 moves along a path through the surgical end effector 1000. You can guide it. When the launch member 1200 is in an operable configuration, for example, the channel slot 1028 is configured to receive the foot portion 1206 of the launch member 1200 and the anvil slot 1103 receives the upper fin 1208 of the launch member 1200. When a portion of the launch member 1200 is positioned in the channel slot 1028 and / or the anvil slot 1103, the launch member 1200 can be aligned with or nearly aligned with axis A. The channel slot 1028 and / or the anvil slot 1103 guide the launch member 1200 from the initial position to the second position with respect to the cartridge body 1042, for example, with the launch member 1200 and the axis A. Alignment can be maintained.
0090As briefly mentioned above, in various surgical staple cartridge embodiments, the surgical staples are supported on a movable staple driver supported within the cartridge body. Various exemplary end effector embodiments drive the wedge thread assembly distally through the staple cartridge and contact the staple driver, pumping the staples out of their individual cavities in the cartridge body and with a closed anvil. Wedge thread assembly 1250 is used, which is configured to form a contact. In at least one exemplary embodiment, the wedge thread 1250 is positioned within the staple cartridge 1040. Therefore, each new staple cartridge 1040 has its own wedge thread that is operably supported inside. When the clinician properly seats the new staple cartridge 1040 in the elongated channel, the wedge thread 1250 straddles the instrument drive shaft 1300 and launches 1200, as shown, for example, in Figures 60, 88, and 89. Is configured to engage. As can be seen in those drawings, the illustrated wedge thread assembly 1250 can include a thread body 1414, a flange 1410, and a wedge 1252. The thread body 1414 can be positioned around a portion of the instrument drive shaft 1300 when the wedge thread assembly 1250 is positioned within the elongated channel 1020. The thread body 1414 can be configured such that the thread body 1414 avoids contact with the device drive shaft 1300 when the thread body 1414 is positioned around the device drive shaft 1300. The thread body 1414 may include, for example, a contour 1412 that curves over and / or around the instrument drive shaft 1300. In such an embodiment, for example, the flange 1410 extends between the thread body 1414 and the wedge 1252, respectively. In addition to that, the thread body 1414 is the launcher body. It has a notch 1415 configured to accept a portion of 1203. Primarily with reference to FIG. 89, the flange 1410 can extend substantially parallel to the foot portion 1206 of the launch member 1200 when the launch member 1200 engages the wedge thread assembly 1250.
0091When the new staple cartridge 1040 is properly installed in the elongated channel 1020, by first activating the launch member 1200 (eg, by rotating the instrument drive shaft 1300), a portion of the launch member body 1203 is wedged. Entering the notch 1415 of thread 1250, the launcher 1200 aligns with the elongated slot 1046 of the cartridge body 1042 (FIG. 60), the channel slot 1028 of the elongated channel 1020, and the anvil slot 1103 of the anvil 1100, and staples. The launching member 1250 can be advanced distally through the cartridge 1040. Therefore, wedge threads may also be referred to herein as "aligning members". When the staple cartridge 1040 is properly installed in the elongated channel, activating the launch member 1200 does not align and engage with the notch 1415 of the wedge thread 1250, and the launch member 1200 is the channel of the elongated channel 1020. It remains out of alignment with the anvil slot 1103 of slot 1028 and anvil 1100, thereby preventing the launching member 1250 from being fired.
0092After the new staple cartridge 1040 is properly placed in the elongated channel 1020, the clinician fires the launcher by applying a first rotational motion to the instrument drive shaft 1300. Once the launch member 1250 is driven distally through the staple cartridge 1250 to its most distal position, a counter-rotational motion is applied to the instrument drive shaft 1300 and the launch member 1250 is external to the surgical staple cartridge 1040. Returned to the starting position, the used cartridge can be removed from the elongated channel 1020 and a new staple cartridge can be installed inside. When the launch member 1250 is returned to its starting position, the wedge thread 1250 remains at the distal end of the staple cartridge and does not return with the launch member 1200. Therefore, when the launching member 1200 moves proximally out of the staple cartridge 1040 and the anvil slot 1103 of the anvil, the rotational movement of the instrument drive shaft 1300 causes the launching member 1200 to swivel slightly into an inoperable position. That is, when the launcher 1200 is in an inoperable position (outside the cartridge), the clinician removes the used cartridge 1040, closes the anvil 1110 and launches it without replacing it with a new cartridge containing the new wedge thread 1250. When attempting to launch member 1200, the launching member 1200 cannot advance distally through the elongated channel 1020 because there is no wedge thread aligned with the launching member 1200. Therefore, such a configuration prevents the clinician from inadvertently firing the launching member 1200 in the absence of the cartridge.
0093In such an exemplary embodiment, the launching member 1200 can be approximately aligned with axis A when the launching member 1200 is oriented in an operable configuration, whereby the launching member 1200 passes through the end effector 1000. Can move along the established path. Axis A is stearyl anvil 1100 can be substantially perpendicular to the cartridge deck 1044 Puru forming surface 1104 and / or staple cartridge 1040 (FIG. 60). In another exemplary embodiment, the axis A can be oriented at an angle to the staple forming surface 1104 of the anvil 1100 and / or the cartridge deck 1044 of the staple cartridge 1040. Further, in at least one exemplary embodiment, axis A can extend through the center of surgical end effector 1000, and in other exemplary embodiments, axis A is either surgical end effector 1000. Can be positioned on the side of.
0094Figures 91-97 show one exemplary form of surgical end effector 1400 with a unique novel launch lockout configuration. As seen in FIGS. 91-95, when the launching member 1200 is in its initial position, the launching member 1200 advances distally through the end effector due to misalignment between the launching member 1200 and the channel slot 1028 and anvil slot 1103. It is an inoperable form that prevents it from happening. The launch member 1200 may be held in an inoperable form by a launch lockout section designated as 1418 overall. Primarily with reference to FIGS. 91-93, in at least one form, the launch lockout portion 1418 includes a first lockout groove or notch 1402 formed in an elongated channel 1020. However, in other exemplary embodiments, the first lockout notch 1402 forms an opening in, for example, the first grip 1004, the second grip 1006, the elongated channel 1020, and / or the anvil 1100. can do. In various exemplary embodiments, the first lockout notch 1402 is such that when the launch member 1200 is in an inoperable configuration, the first lockout notch 1402 holds and engages a portion of the launch member 1200. Is placed inside the surgical end effector 1400. The first lockout notch 1402 can be, for example, near, adjacent to, and / or connected to channel slot 1028 of elongated channel 1020. Primarily with reference to FIG. 91, the channel slot 1028 can have a slot width along its length. In at least one exemplary embodiment, the first lockout notch 1402 is such that the combined width of the channel slot 1028 and the first lockout notch 1402 exceeds the slot width of the channel slot 1028. Can be extended from. As can be seen in FIG. 91, when the launching member 1200 is inoperable, the foot portion 1206 of the launching member 1200 is the first locker.
0095When the new staple cartridge 1040 is properly installed in the elongated channel 1020, by initiating the launch stroke, the launch member engages the wedge thread 1250 positioned within the staple cartridge 1040, thereby the launch member 1200. Moves and is driveably aligned with the elongated slot 1046 of the cartridge body 1042, the channel slot 1028 of the elongated channel 1020, and the anvil slot 1103 of the anvil 1100, through which the launcher 1250 is advanced distally. Can be done. As the launch member 1200 moves from the initial position to the second position with respect to the staple cartridge 1040, the launch member 1200 can move, for example, beyond the first lockout notch 1402. The first lockout notch 1402 can have a length of, for example, about 0.64 cm (0.25 inch). In some other exemplary embodiments, the first lockout notch 1402 is, for example, about 0.38 cm (0.15 inch) to about 0.64 cm (0.25 inch) in length, or, for example, about 0.64 cm (0.25 inch). It can have a length from inches) to about 2.5 cm (1.0 inches).
0096With reference to FIGS. 93 and 94, the surgical end effector 1400 can be configured to accommodate the upper fins 1208 of the launch member 1200 when the launch member 1200 is inoperable. For example, the launch lockout section 1418 may include a second lockout groove or notch 1404 within the anvil 1100. In the illustrated exemplary embodiment, the second lockout notch 1404 can be, for example, near, adjacent to, and / or connected to anvil slot 1103 of anvil 1100. The anvil slot 1103 can have a width along its length. In at least one exemplary embodiment, the second lockout notch 1404 is such that the combined width of the anvil slot 1103 and the second lockout notch 1404 exceeds the slot width of the anvil slot 1103. Can be extended from. The second lockout notch 14040 can extend the length or distance of the surgical end effector 1400. The launch member 1200 can be configured to engage a second lockout notch 1404 along its length when the launch member 1200 is inoperable. As the launch member 1200 moves from the initial position to the second position with respect to the staple cartridge 1040, the launch member 1200 can move, for example, beyond the second lockout notch 1404. The second lockout notch 1404 can have a length of, for example, about 0.64 cm (0.25 inch). In some other exemplary embodiments, the second lockout notch 1404 is, for example, about 0.38 cm (0.15 inch) to about 0.64 cm (0.25 inch) in length, or, for example, about 0.64 cm (0.25 inch). Inch) ~ Approximately 2.5 cm (1. Can have a length of 0 inches). Primarily with reference to FIG. 93, the first lockout notch 1402 can extend from channel slot 1028 in the first direction X, and the second lockout notch 1404 is from anvil slot 1103 to the second. Can be extended in direction Y. In at least one exemplary embodiment, the first direction X can be approximately laterally opposite to the second direction Y. In such an exemplary embodiment, when the launch member 1200 moves into an inoperable configuration, the foot portion 1206 of the launch member 1200 can swivel into the first lockout notch 1402 and is above the launch member 1200. Fin 1208 can swivel into the second lockout notch 1404.
0097Primarily with reference to FIGS. 92-94, when the launch member 1200 is oriented in an inoperable configuration, the corresponding portion of the launch member 1200 engages the first and second lockout notches 1402, 1404. The launch member 1200 can be positioned at least partially within the first and second lockout cutouts 1402, 1404 when the launch member 1200 is inoperable. The launching member 1200 can shift into the first and second lockout notches 1402, 1404 as the launching member 1200 moves into an inoperable configuration. Further, when the launch member 1200 is oriented in an operable configuration, the launch member 1200 can engage and disengage the first and second lockout cutouts 1402, 1404.
0098One or more parts of the surgical end effector 1400 block the launching member 1200 when the launching member 1200 is oriented in an inoperable configuration, limiting or preventing the launching member 1200 from moving through the surgical end effector 1400. (See, for example, Figure 95). For example, the first grip 1004, the second grip 1006, the elongated channel 1020, and / or the anvil 1100 can be configured to block the launching member 1200 when it is in an operable configuration. In some exemplary embodiments, the first lockout cutout 1402 has a first blocking surface or edge 1406 (FIGS. 91 and 92) formed on it and a second lockout cutout. The notch 1404 has a second blocking surface or edge 1408 (FIG. 94) formed on it. If the launching member 1200 attempts to launch the launching member 1200 in an inoperable configuration, the corresponding portion of the launching member 1200 contacts one or both of the first and second blocking surfaces 1406, 1408, and the launching member 1200 Prevents moving from the initial position to the second position. In at least one exemplary embodiment, the surgical end effector 1400 does not necessarily have to have both a first blocking edge 1406 and a second blocking edge 1408.

The retaining pins 1514 (FIGS. 98, 100, 101, and 103) can be configured to urge the bearing segment 1304 against the first side of the bore 1512, thereby allowing the appliance drive shaft 1300 to urge. For example, it is held in an inoperable position, and the instrument drive gear 1302 is held, for example, out of engagement with a third ring gear 768. In some exemplary embodiments, the retaining pin 1514 may spring up such that the retaining pin 1514 exerts a force on the bearing segment 1304 to move the instrument drive shaft 1300 towards an inoperable position. it can. The instrument drive shaft 1300 is such that another force overcomes the force exerted by the holding pin 1514 to move the instrument drive shaft 1300 towards an operable position, for example the instrument drive gear 1302 engages the third ring gear 768. You can remain in an inoperable position until you do.
0102Primarily with reference to FIGS. 103 and 104, the bearing segment 1304 can be positioned in contact with the second side of the bore 1512 of the bearing sleeve 1511 when the appliance drive shaft 1300 is in the operable position. In various exemplary embodiments, the force exerted by the retaining pins 1514 (FIGS. 98, 100, 101, and 103) is overcome and the bearing segment 1304 is moved tangent to the second side of the bore 1512, thereby. The appliance drive shaft 1300 is, for example, in an operable position, and the appliance drive gear 1302 is engaged, for example, with a third ring gear 768. As described herein, the urging element 1520 can exert a force on the bearing segment 1304, for example, to overcome the force exerted by the holding pin 1515.
0103The surgical end effector 1500 may be movable between the position of the first set (see, eg, FIG. 103) and the position of the second pair (see, eg, FIG. 101). It can be equipped with a force element 1520. The position of the second set can be distal to the position of the first set with respect to the end effector drive housing 1510. When the urging element 1520 is in the first set of positions, the urging element 1520 can be configured to move, for example, the instrument drive shaft 1300 to an operable position. When the urging element 1520 is in the second set of positions, the urging element 1520 can release the instrument drive shaft 1300 so that, for example, the instrument drive shaft can be returned to the inoperable position.
0104The urging element 1520 can be an independent element that can be positioned within the surgical end effector 1500. The urging element 1520 can be held movably within, for example, the surgical end effector 1500, and can be operably engaged with, for example, the staple cartridge 1040. The staple cartridge 1040 can be equipped with an urging element 1520. In some exemplary embodiments, the urging element 1520 can be integrally formed with, for example, the wedge thread assembly 1250 of the staple cartridge 1040, and the urging element 1520 is held movably within, for example, the staple cartridge 1040. can do. In such an exemplary embodiment, the urging element 1520 moves through the elongated channel 1020, for example, as the wedge thread assembly 1250 and / or the launching member 1200 travels through the elongated channel 1020 during the launch stroke. Can be done.
0105Primarily with reference to FIG. 99, the urging element 1520 can include an urging body 1522 and a leg body 1526 extending from the urging body 1522. The urging body 1522 can be positioned around a portion of the instrument drive shaft 1300 within the surgical end effector 1500. In some exemplary embodiments, the urging body 1522 is configured to avoid contact between the urging body 1522 and the instrument drive shaft 1300 when the urging body 1522 is positioned around the instrument drive shaft 1300. be able to. The urging body 1522 can include, for example, a contour 1524 that curves over and / or around the instrument drive shaft 1300. The leg body 1526 can extend along either part of the elongated channel 1020 and / or either side of the instrument drive shaft 1300. The urging element 1520 may also include at least one extension or wedge 1528. As described herein, the wedge 1528 can movably engage the bearing sleeve 1511 and / or the bearing segment 1304 to move the instrument drive shaft into an operable position. The urging element 1520 can also include at least one spring 1530.

In such an exemplary embodiment, the instrument drive shaft 1300 can be held in an inoperable position by the holding pin 1514.
0107Next, referring to FIG. 103, by placing the staple cartridge 1040 in the elongated channel 1020, the urging element 1520 moves proximally against the force of the spring 1530 to reach the position of the first set. There, the wedge 1528 movably engages the bearing sleeve 1511 and the bearing segment 1304 to urge the bearing segment 1304 and the appliance drive gear 1302 of the fixture drive shaft 1300 to mesh and engage with the third ring gear 768. .. Subsequent activation of the launch drive system as described herein results in the launch of the launch member 1200. In some exemplary embodiments, a portion of the staple cartridge 1040 is configured to come into direct contact with the urging element 1520 to move the urging element 1520 to the position of the first set. In another exemplary embodiment, a portion of the staple cartridge 1040 can contact another element of the surgical end effector 1500, such as the launching member 1200, to move the urging element 1520 into the first set of positions. It is configured to move to. In yet another exemplary embodiment, the staple cartridge 1040 has an urging element 1520 formed integrally with it.
0108In various exemplary embodiments, the urging element 1520, for example, during the launch stroke, the launching member 1200 and / or the wedge thread assembly 1250 is elongated by the instrument drive shaft 1300. Driven through, it can travel through the elongated channel 1020 of the surgical end effector 1500. The urging element 1520 can be integrally formed with and / or secured to the wedge thread assembly 1250 of the staple cartridge 1040. In such an exemplary embodiment, when the staple cartridge 1040 is first seated in the elongated channel 1020, the wedge thread assembly 1250 and urging element 1520 are positioned in their initial position relative to the staple cartridge 1040 and / or the elongated channel 1020.

The initial position of the urging element 1520 is such that the urging element 1520 movably engages the bearing sleeve 1511 of the end effector drive housing 1510 to bring the instrument drive shaft 1300 into an operable position. It is possible to correspond to the position of the first set, such as moving with. During the launch stroke, the wedge thread assembly 1250 and urging element 1520 can be moved, for example, away from the initial or first set position. The urging element 1520 can be moved, for example, to a second set of positions. When the urging element 1520 moves beyond the position of the first set to the position of the second set, the urging element 1520 engages the bearing sleeve 1511 of the end effector drive housing 1510 to engage the instrument drive shaft 1300. It may not be held in an operable configuration. When the urging element 1520 moves to the second set of positions, the urging element 1520 may not urge the instrument drive gear 1302 of the instrument drive shaft 1300 to engage the third ring gear 768. , Channel slot 1028, anvil slot 1103, and / or elongated slot 1046 of staple cartridge 1040 are instrument drive teeth of instrument drive shaft 1300.
0109In at least one exemplary embodiment, the launch member 1200 and / or the instrument drive shaft 1300 may drive the wedge thread assembly 1250 and / or the urging element 1520 to a second set of positions during the launch stroke. it can. In various exemplary embodiments, the launch member 1200 can return to its initial position upon completion of the launch stroke, but, for example, the wedge thread assembly 1250 containing the urging element 1520 remains in the second set of positions. Can be done. The launching member 1200 can return to, for example, a proximal position within the surgical end effector 1500, and the urging element 1520 can remain, for example, at a distal position within the surgical end effector 1500. When the launch member 1200 is in the initial position and the urging element 1520 is in the second set position, the bearing segment 1304 of the fixture drive shaft 1300 moves the fixture drive shaft 1300 to, for example, an inoperable position to drive the fixture. The gear 1302 can be moved and shifted within the bearing sleeve 1511 so that it disengages, for example, the third ring gear 768. In various exemplary embodiments, the instrument drive shaft 1300 is, for example, until the urging element 1520 is pulled back into the first set position and / or the replacement urging element 1520 is in the first set position. Can remain in an inoperable position until positioned in. For example, a used staple cartridge 1040 is removed from the elongated channel 1020 and replaced with a replacement staple cartridge 1040 that can include an urging element 1520 located in the first position. When the replacement staple cartridge 1040 is positioned within the elongated channel 1020, its urging element 1520 shifts the instrument drive gear 1302 to engage, for example, the third ring gear 768, for example to an operable position. To do. In such an exemplary embodiment, the surgical end effector 1500 can be prevented from being refired when the cartridge 1040 is not seated in the elongated channel 1020 or the used cartridge 1040 is seated. .. In addition, if the staple cartridge is not properly seated in the elongated channel 1010, thereby causing the urging element 1520 to move the instrument drive shaft 1300 and engage with the third ring gear 768, it fires. Member 1200 cannot be fired.
0110As mentioned above, the surgical instrument system has a surgical housing and a replaceable end that can be connected to the surgical housing for use during the surgical procedure and then separated from the housing after use. It can include an effector assembly and a motor and / or actuator configured to fire the end effector. In various situations, the surgeon can choose from several replaceable end effectors for use during the surgical procedure. For example, the surgeon first selects a first replaceable end effector configured to staple and / or incise the patient's tissue, including, for example, a staple cartridge length of about 15 mm (mm). , A first incision may be made in the patient's tissue. In such an embodiment, the cutting edge and / or the staple drive thread can be advanced by a drive screw along a length of about 15 mm of the staple cartridge to cut and staple the patient's tissue by about 15 mm. The surgeon then selects a second replaceable end effector, which can also include a staple cartridge length of approximately 30 mm, also configured to staple and / or incise the patient's tissue. A second incision may be made in the patient's tissue. In such an embodiment, the patient's tissue is cut by about 30 mm and stapled so that the cutting edge and / or the staple drive thread can be advanced by the drive screw along a length of about 30 mm of the staple cartridge. The surgeon also makes an incision in the patient's tissue by selecting a replaceable end effector configured to staple and / or incise the patient's tissue, for example, containing a staple cartridge length of approximately 45 mm. You may. In such an embodiment, the patient's tissue is cut by about 45 mm and stapled so that the cutting edge and / or the staple drive thread can be advanced by the drive screw along a length of about 45 mm of the staple cartridge. Surgeons also say, for example, about 60m A replaceable end effector may be selected to make an incision in the patient's tissue, which can also be configured to staple and / or incise the patient's tissue, including a staple cartridge length of m. In such an embodiment, the patient's tissue is cut by about 60 mm and stapled so that the cutting edge and / or the staple drive thread can be advanced by the drive screw along a length of about 60 mm of the staple cartridge. The 15 mm, 30 mm, 45 mm, and / or 60 mm lengths of the end effectors described above are examples. Other lengths can be used. In certain embodiments, for example, the first end effector can include a staple cartridge having a length x and the second end effector can include a staple cartridge having a length of about 2 x x. The third end effector can include a staple cartridge having a length of about 3 × x, and the fourth end effector can include a staple cartridge having a length of about 4 × x.
0111For some surgical instruments that utilize replaceable end effectors with different lengths, the drive screws for each of the different replaceable end effectors are individually adapted to the different lengths of the associated replaceable end effectors. They may be the same, except that the lengths of the drive screws may be different. For example, a replaceable end effector with a 30 mm staple cartridge may require a longer drive screw than the drive screw of a replaceable end effector with a 15 mm staple cartridge. However, in each example of such a surgical instrument system, each drive screw utilizing the same screw pitch and / or screw lead, described in more detail below, is used to fully fire each end effector. Depending on the length of the end effector, it may be necessary for the motor to rotate the drive shaft at different times or rotation speeds. For example, a drive screw that provides a 30 mm launch stroke may require twice as many revolutions to fully operate as a drive screw that provides a 15 mm launch stroke. In such a surgical instrument system, electronic communication between the surgical housing and the replaceable end effector is utilized so that the electric motor in the surgical housing is relative to the length of the attached replaceable end effector. It is possible to guarantee that the rotation is performed by an appropriate number of rotations. For example, a replaceable end effector is an electronic circuit that can be identified by the surgical instrument system so that the motor can be rotated by the appropriate number of revolutions for the end effector to which the surgical instrument system is attached. It may be included. In addition to or instead of the above, the replaceable end effector may include a sensor that senses the end effector when it is fully operational. In such an embodiment, the sensor can communicate with a controller in the housing configured to stop the motor upon receiving the appropriate signal. Surgical housens, although suitable for their intended purpose
0112As outlined above, end effectors of different lengths can be used in the same surgical instrument system. In the surgical instrument system described above, replaceable end effectors with different firing lengths include drive screws that rotate different times to accommodate different firing lengths. To adapt to the different speeds required for different drive screws, the motor driving the drive screw may have a longer duration or longer depending on whether a longer or shorter launch length is required. It operates at shorter durations and / or at higher or lower speeds. According to a replaceable end effector embodiment described below, a surgical instrument system with a motor can be configured to rotate for a fixed or set number of revolutions to activate end effectors with different firing lengths. it can. Operating the motor at a fixed number of revolutions may eliminate the need for the surgical instrument system to determine the length of the end effector. Each end effector of the embodiments described below allows a working portion of the end effector, such as a cutting edge, to move the entire length of a particular end effector at a fixed rotation speed of the motor, thread pitch and / or thread lead. Includes drive screws with.
0113With reference to FIG. 105, the drive screw 1700 can be rotated in the first direction to move the cutting edge 1730 of the end effector 1740 in the distal direction indicated by arrow E. In use, the drive screw 1700 can be fixed or rotated a set number of times to advance the cutting edge 1730 to the full firing length indicated by length L in FIG. 105. For each rotation of the drive screw 1700, in certain embodiments, the thread pitch, thread lead, and / or distance between adjacent windings of thread 1708 on the drive thread 1700, as described in more detail below. The cutting edge 1730 can be moved in the direction of arrow E by an amount equal to. In various embodiments, the first drive screw can include a first set of properties that determine the first firing length, and the second drive screw is a second that determines the second firing length. The characteristics of the first set can be different from the characteristics of the second set.
0114Then, referring to FIGS. 106A, 107, 108A, and 109A, in addition to the above, the distance between the windings of the thread on the drive screw can be proportional to the angle of the thread on the drive screw. In other words, the angle at which the thread is placed on the drive thread can be a characteristic of the drive thread that determines the thread pitch and / or thread reed of the drive thread. In an embodiment in which the drive screw and the motor driving the drive screw rotate by a fixed number of revolutions, the longer drive screw used in the longer end effector is more than the shorter drive screw used in the shorter end effector. Also long screw pitches and / or screw leads are available. The drive thread 1700 of FIG. 106A includes a single thread A arranged on the drive thread 1700 at an angle α with respect to the longitudinal axis 1701, where the thread A has a thread pitch and / or a length X. Determine the screw lead. FIG. 106B shows a cross-sectional view of the drive screw 1700 and the single thread A. In certain embodiments, the drive screw 1700 may include more than one thread, as described in more detail below.
0115FIG. 107A shows a drive thread 1700'that can include a first thread A'and a second thread B'. FIG. 107B shows a cross-sectional view of the drive thread 1700'in which the first thread A'and the second thread B'are positioned on the drive thread 1700' about 180 ° out of phase with each other. In various embodiments, a drive thread having a first thread A'and a second thread B'is per unit length as compared to a drive thread using a single thread A'or B'. The number of threads can be increased. If the drive thread contains more than one thread, the distance from the first thread winding to the second thread adjacent winding is called the "thread pitch". The distance from one winding of a thread to the next winding of the same thread is called a "thread reed". For a drive thread with a single thread, the thread pitch and thread lead are the same. For example, referring to FIG. 107A, the distance from the winding of thread A'to the adjacent winding of thread B'determines the thread pitch of the drive thread 1700'. The distance from one winding with thread A'to the next winding with thread A'determines the thread lead of the drive thread 1700'. Therefore, the thread lead of the drive thread 1700'in Figure 107A is equal to X'and the thread pitch is equal to X'/ 2. The drive thread 1700 shown in Figures 106A and 106B has a single thread, so both the thread pitch and the thread lead are equal to X. The thread reed of the drive screw determines the length by which the launching member, such as the cutting edge 1730 and / or the staple driver, moves with respect to one rotation of the drive screw.
0116Referring to FIG. 107A, the first thread A'and the second thread B'are respectively arranged at an angle β with respect to the longitudinal axis 1701 of the drive screw 1700'. The angle β is smaller than the angle α, and the screw reed X'of the drive screw 1700'in FIG. 107A is larger than the screw reed X of the drive screw 1700 shown in FIG. 106A. For one rotation of the drive screw 1700', the cutting edge moves by the length X'along the drive screw 1700'. For example, the thread lead X'can be twice the thread pitch of the drive thread 1700 shown in FIG. 106A or twice the thread lead X, and as a result, the cutting edge engaged with the drive thread 1700' in Figure 107A. For one rotation of the drive screw 1700', the distance is twice as long as that of the cutting edge engaged with the drive screw 1700 in FIG. 106A.
0117FIG. 108A shows the first thread A'', the second thread B'', and the third thread C extending at an angle γ with respect to the longitudinal axis 1701 of the drive screw 1700'', respectively. '' Indicates a drive screw 1700'' that can include. FIG. 108B is a cross-sectional view of the drive screw 1700'' showing threads A'', B'', and C'' arranged out of phase by about 120 °. The angle γ is smaller than the angle β in FIG. 107A, and the screw reed X of the drive screw 1700'' in FIG. 108A is larger than the screw reed X'of the drive screw 1700'shown in FIG. 107A. Similarly, FIG. 109A shows the first thread A'''', the second thread B'''', and the second thread B'''' extending at an angle δ with respect to the longitudinal axis Z of the drive screw 1700'''', respectively. Shown is a drive thread 1700'''' that can include 3 threads C'''' and a 4th thread D''''. FIG. 109B is a cross-sectional view of the drive screw 1700''', showing threads arranged out of phase by about 90 °. The angle δ is smaller than the angle γ, and the thread reed X'''of the drive screw 1700'''is larger than the drive screw 1700'' in FIG. 108A.
0118An exemplary surgical instrument system may include a housing and a motor in the housing that is configured to rotate a fixed number of revolutions, thereby, for example, the drive screw of a connected replaceable end effector. Is turned by 30 turns. The surgical instrument system can further include multiple replaceable surgical stapler end effectors, each of which can include, for example, a cutting edge and / or a staple driver driven by a drive screw. In at least one such embodiment, the first replaceable end effector can include, for example, a staple cartridge having a length of 15 mm. The drive screw 1700 shown in Figures 2A and 2B can be used for the first replaceable end effector. Since the thread reed X can be set to, for example, 0.5 mm, the cutting edge and / or staple driver can move the 15 mm length of the staple cartridge in 30 revolutions of the drive screw 1700. The second replaceable end effector can include, for example, a staple cartridge having a length of 30 mm and a drive screw such as the drive screw 1700'' shown in FIGS. 107A and 107B. The thread lead X'of the drive screw 1700'can be set to 1.0 mm, for example, so the cutting edge and / or staple drive should move the staple cartridge 30 mm in 30 turns of the drive screw 1700'. Can be done. Similarly, a third replaceable end effector with a staple cartridge having a length of 45 mm, for example, has a screw lead X'' of 1.5 mm, such as the drive screw 1700'' in Figures 108A and 108B. Since the drive screw can be included, the cutting edge and / or staple drive travels 45 mm length of the staple deck in 30 turns of the drive screw 1700''. A fourth replaceable end effector, for example with a staple cartridge having a length of 60 mm, is, for example, 2.
0119FIG. 110 shows the cutting edge 1730 of FIG. 105 removed from the rest of the end effector 1740. The cutting edge 1730 includes a passage 1732 through which the drive screw 1700 passes. The side portion 1736 can include a recess such as a groove 1734 that forms the inner wall of the passage 1732 and is configured to accommodate the thread 1708 of the drive screw 1700, for example. Groove 1734 is oriented at an angle ε corresponding to the angle of thread 1708 on the drive screw 1700. For example, if the thread 1708 is set to the angle α shown in FIG. 106A, the angle ε of the groove 1734 can also be set to the angle α. Correspondingly, the angle ε of groove 1734 can be set, for example, to the corresponding drive screw angles β, δ, and / or γ used with it.
0120In various embodiments, the side portion 1736 can be incorporated into a window 1738 defined in the shaft portion 1746 of the cutting edge 1730, as shown in the exploded view of FIG. 110. In certain embodiments, the cutting edge 1730 can include an integral side portion. In at least one embodiment, the side portions can be provided with a suitable groove angle ε that matches the angle of thread 1708 on the drive screw 1700, which can be formed in the passage 1732 defined therein. A cutting edge 1730 having an appropriate groove angle ε for a particular drive screw can be provided in a number of ways. In certain embodiments, it is possible to provide a general purpose cutting edge 1730 that does not include the side portion 1736 incorporated into the window 1738 of its shaft portion 1746, in which case the side portion 1736 from various sets of side portion 1736. Such an assembly can be used with a particular drive screw, as various sets of side portions 1736 can be provided so that the desired set of can be selected and then combined with the general purpose cutting edge 1730. Can be done. For example, a first set of side portions 1736 can form a cutting edge 1730 used with a first drive screw when combined with a cutting edge 1730, and a second set of side portions 1736 can be cut. When combined with the blade 1730, it can form a cutting edge 1730 used with a second drive screw, and so on. In certain other embodiments, the cutting edge 1730 may comprise a side portion formed integrally with it. In at least one such embodiment, for example, a groove 1734 with a tap can be formed at an angle ε that matches the angle of the thread 1708 of a particular drive screw 1700.
0121FIG. 111 shows a drive screw 1700 connected to a drive shaft 1750 via an intermediate gear 1720 arranged between them. The drive shaft 1750 is rotated by a motor. As mentioned above, the motor can complete a fixed or set number of revolutions, so that the drive shaft 1750 can rotate a fixed number of revolutions R. In certain embodiments, the number of rotations R rotated by the drive shaft 1750 may be equal to the fixed number of rotations rotated by the motor. In an alternative embodiment, the number of rotations R rotated by the drive shaft 1750 may be greater than or less than the fixed number of rotations rotated by the motor. In various embodiments, one or more gears located between the motor and the drive shaft 1750 allow the drive shaft 1750 to complete more or less rotation than the motor. In certain embodiments, the drive shaft 1750 can include an external spline gear 1752 that surrounds and / or is attached to the distal end 1754 of the drive shaft 1750. The outer spline gear 1752 can engage the inner spline gear 1724 defined within the intermediate gear 1720 to transmit the rotation of the drive shaft 1750 to the intermediate gear 1720. As a result, in at least one embodiment, the intermediate gear 1720 can complete the same rotation R as the drive shaft 1750.
0122The intermediate gear 1720 can include a second gear 1722 that surrounds and / or is attached to a gear 1712 that surrounds the proximal end 1702 of the drive screw 1700. The second gear 1722 of the intermediate gear 1720 defines the first diameter D1, and the gear 1712 at the proximal end 1702 of the drive screw 1700 defines the second diameter D2. The second diameter D2 can be different from the first diameter D1. When the first diameter D1 and the second diameter D2 are different, they can determine gear ratios other than 1: 1. As shown in FIG. 111, in certain embodiments, the diameter D1 is greater than the diameter D2 so that the drive screw 1700 completes more rotation R'than the rotation R rotated by the drive shaft 1750 and the intermediate gear 1720. It can be big. In an alternative embodiment, the diameter D1 can be smaller than the diameter D2 so that the drive screw 1700 turns with a turn R'less than the turn R turned by the drive shaft 1750 and the intermediate gear 1720.
0123The gear ratio between the second gear 1722 of the intermediate gear 1720 and the gear 1712 of the drive screw 1700 is such that when the drive shaft 1750 completes its fixed speed, the drive screw 1700 completes a specific speed. Can be set. If the intermediate gear 1722 is part of a replaceable end effector assembly, the gear ratio between each intermediate gear 1722 and the drive screw 1700 in the replaceable end effector assembly is a fixed rotation of the motor in the surgical housing. It can be set so that it can be turned for several minutes. For example, referring to FIG. 111, the drive shaft 1750 turns a predetermined 30 turns, the replaceable surgical stapler contains a 15 mm staple cartridge, and the end effector contains a drive screw with a 0.25 mm thread lead. If so, the drive screw completes 60 revolutions and advances the cutting edge and / or staple driver by the length of 15 mm of the staple cartridge. In at least one embodiment, the intermediate gear 1720 can be sized so that the second internal gear 1722 has a diameter D1 that is twice the diameter D2 of the external gear 1712 of the drive screw 1700. As a result, when the drive shaft 1750 completes 30 rotations, the drive screw 1700 completes 60 rotations. If the second replaceable surgical stapler contains a 30 mm staple cartridge, the drive screw with a 0.25 mm thread reed completes 120 revolutions and advances the cutting edge and / or staple driver by 30 mm length. Let me. The replaceable surgical stapler intermediate gear 1720 can be sized so that the second internal gear 1722 has a diameter D1 that is four times the diameter D2 of the external gear 1712 of the drive screw 1700. As a result, when the drive shaft 1750 completes 30 rotations, the drive screw 1700 completes 120 rotations.
0124Returning to FIG. 105, in certain embodiments, the launch path of the launching member, eg, cutting edge 1730, can be straight. In certain embodiments, the firing patch can be curved and / or curved. In certain embodiments, the drive screw 1708 can be flexible so that the drive screw 1708 can follow the lateral movement of the launcher, eg, along curved and / or curved paths. .. In certain embodiments, a portion of the launching member is laterally displaced relative to the drive screw 1708, eg, along a curved and / or curved path, while the rest of the launching member is driven screw 1708. The launching member can be flexible or can include at least one flexible portion so that it is not laterally displaced relative to. In certain embodiments, the firing length may be defined by the distance traveled by the firing member along the firing path, regardless of the overall net displacement. In various other embodiments, the firing length may be defined by the total net displacement of the firing member, regardless of the firing path.
0125In various embodiments, kits may be provided that are used with a surgical instrument system that includes various interchangeable end effectors of different lengths. In certain embodiments, the kit may include a series of replaceable end effectors of different lengths, from which the surgeon may choose to use in surgery on the patient. The kit can also include several replaceable end effectors of each length. In certain embodiments, the kit may include a set of interchangeable end effectors of different lengths, predetermined for a particular surgical procedure. For example, certain surgical procedures may require a 15 mm incision first, then a second 15 mm incision, and finally a 30 mm incision. The surgical kit for this surgical procedure can include three replaceable end effectors configured to incise and staple the patient's tissue. The first two replaceable end effectors can contain a length of about 15 mm and the third replaceable end effector can contain a length of about 30 mm.

The distal ball joint segment 2324 is formed on, adapted to drive and engage a first proximal component or dovetail joint 2307 formed in the proximal ball joint segment 2306. Has a first distal construct or dovetail fitting 2325, whereby the first distal dovetail fitting 2325 drives and engages the first proximal dovetail fitting 2307 on the distal side. The ball joint segment 2324 and the proximal ball joint segment 2306 form an internal articulated ball assembly. In addition, the articulated joint 2300 further comprises a distal ball segment 2330 supported on the distal ball joint segment 2324, on which a second on the proximal ball joint segment 2310 is formed. It has a second distal side diameter living body or dovetail fitting 2332 adapted to drive and engage the proximal construction or dovetail fitting 2312 of the. Distal cable segments 444, 445, 446, 447 are attached to the distal ball segment 2340 and extend through passage 2328 within the distal articular junction tube 2320. When the proximal ball joint segment 2310 and the distal ball joint segment 2324 are joined together, they form a joint ball 2340 that is movably pivotally supported on the internal joint ball. The distal articular junction tube 2320, the distal ball segment 2340, and the distal cable segments 444, 445, 446, 4447 may be collectively referred to as the proximal articulated drive row assembly 2316.
0131As can be seen in FIG. 115, the distal portion of the elongated shaft assembly 2200 is held as a whole by the following joint segments being aligned and held together by the distal connector 2217 or the distal outer tubing portion 2218. It may be assembled to form a distal dovetail joint assembly called 2290: 2226, 2332, 2325, 2280, 2244, and 2264. Similarly, in the elongated shaft assembly 2200, the proximal connector member 2212 or the proximal outer tubing segment 2214 aligns and holds the following joint segments to each other, overall 2292: 2228, 2312, 2307. , 2270, 2234, and 2254 may be assembled to form a proximal dovetail joint assembly.
0132The end effector 1000 may be operably connected to the elongated shaft assembly 2200 as follows. To begin the installation, the clinician moves the locking tube segment 2220 to the first unlocking position shown in FIGS. 115 and 116. As can be seen in those drawings, the locking tube segment has a contact segment 2224 formed at its distal end 2222. When in the unlocked position, the abutment segment 2224 projects distally beyond the proximal dovetail fitting assembly 2292, laterally extending the distal dovetail fitting assembly 2290 to the proximal dovetail fitting assembly 2292. Form a contact surface to be joined. That is, the clinician laterally aligns the distal dovetail fitting assembly 2290 with the proximal dovetail fitting assembly 2292, and then the distal dovetail fitting assembly 2290 contacts the abutment segment 2224 at that point. The distal dovetail fitting assembly 2290 may be slid laterally engaged with the proximal dovetail fitting assembly 2292 until the corresponding proximal and distal joint segments are interconnected simultaneously. The clinician may then move the locking tube segment 2220 distally to a second locking position as shown in FIG. 117. When in that position, the locking tube segment 2220 covers the rapid desorption joint 2210 and prevents any relative lateral movement between the distal dovetail assembly 2290 and the proximal dovetail assembly 2292.
0133Although the various exemplary embodiments described above are configured to operably interface with a robotic system, thereby at least partially operating, the end effectors and elongated shaft components are handheld instruments. It may be effectively used in the state of being connected to. For example, FIGS. 118-120 show a handheld surgical instrument 2400 in which the articulated end effector 1000 may be operably actuated using the various components and systems described above. In the exemplary embodiment shown in FIGS. 118-120, a rapid desorption joint 2210 is used to connect the end effector 1000 to the elongated shaft assembly 2402. To facilitate articulation of the end effector 1000 around the joint 700, the proximal portion of the elongated shaft assembly 2402 includes an exemplary manually actuable joint drive 2410.
0134Then with reference to FIGS. 121-123, in at least one exemplary embodiment, it moves between the proximal outer tube segment 2214 and the proximal drive shaft segment 380'on the proximal drive shaft segment 380'. 4 axially movable joint articulations that are freely axially supported slide) 2410 is included. For example, the articulated cable segment 434A'is attached to a first articulated sliding portion 2420 having a first articuator rod 2422 protruding from it. The articulated cable segment 434B'is attached to a second articulated sliding portion 2430, which is the exact opposite of the first articulated sliding portion 2420. The second joint sliding portion 2430 has a second joint actuator rod 2432 projecting from the second joint sliding portion 2430. The articulated cable segment 454A'is attached to a third articulated sliding portion 2440 having a third articuator rod 2442 protruding from it. The articulated cable segment 454B'is attached to a fourth articulated sliding portion 2450 that is the exact opposite of the third articulated sliding portion 2440. The fourth joint actuator rod 2452 projects from the fourth joint sliding portion 2450. The joint actuator rods 2422, 2432, 2442 and 2452 facilitate the joint ring assembly 2460 to apply joint control movements to the joint sliding parts 2420, 2430, 2440 and 2450, respectively.
0135As seen in FIG. 121, the joint actuator rods 2422, 2432, 2442, 2452 movably pass through the mounting ball 2470, which is axially supported on the proximal outer tube segment 2404. In at least one embodiment, the mounting ball 2470 may be manufactured in the form of segments that are attached together by appropriate fastener configurations (eg, welds, adhesives, screws, etc.). As shown in FIG. 109, the joint actuator rods 2422 and 2432 extend through slot 2472 of the proximal outer tube segment 2404 and slot 2474 of the mounting ball 2470, to which the joint sliding parts 2420, 2430 On the other hand, it is possible to move in the axial direction. Although not shown, joint actuator rods 2442, 2452 likewise extend through slots 2472, 2474 of the proximal outer tube segment 2404 and the mounting ball 2470. The joint actuator rods 2422, 2432, 2442, and 2452 each extend out of the corresponding mounting slot 2472 of the mounting ball 2470 and are operably accepted into the corresponding mounting slot 2466 of the joint ring assembly 2460. See Figure 122.
0136In at least one exemplary embodiment, the articulated ring assembly 2460 is made from a pair of ring segments 2480, 2490 that are joined together, for example, by welding, adhesive, snap mechanism, screws, etc. to form the articular ring assembly 2460. Will be done. The ring segments 2480 and 2490 work together to form the mounting socket 2466. Each articuator rod has a mounting ball 2468 formed on it, and each of them is adapted to be movably accepted within the corresponding mounting socket 2466 of the joint ring assembly 2460.
0137Various exemplary embodiments of the joint drive 2410 may further include an exemplary locking system 2486 configured to hold the joint ring assembly 2460 in working position. In at least one exemplary embodiment, the locking system 2486 comprises a plurality of locking flaps formed on the articular ring assembly 2460. For example, the ring segments 2480, 2490 may be made from a somewhat flexible polymer or rubber material. The ring segment 2480 has a series of flexible proximal locking flaps 2488 formed therein, and the ring segment 2490 has a series of flexible distal locking flaps 2498 formed therein. Has. Each locking flap 2388 has at least one locking stop 2389 formed on it, and each locking flap 2398 has at least one locking stop 2399 formed on it. The locking movement stops 2389, 2399 may help establish the desired locking friction amount with the articulating ball so as to hold the articulated ball in place. In another exemplary embodiment, the locking movement stops 2390, 2390 are configured to mesh and engage various locking recesses formed on the outer circumference of the mounting ball 2470.
0138The operation of the joint drive unit 2410 can be understood by referring to FIGS. 122 and 123. FIG. 122 shows the joint drive unit 2410 in the non-joint joint position. In Figure 123, the clinician manually tilts the articular ring assembly 2460 to move the articular sliding section 2420 axially in the distal "DD" direction, thereby moving the articulated cable segment 434A'to the distal side. I'm moving forward. Such movement of the articular ring assembly 2460 also results in a proximal axial movement of the articular sliding portion 2430, which ultimately pulls the articulation cable 434B proximally. The end effector 1000 is articulated with respect to the longitudinal tool axis "LT-LT" as described above by the push-pull of the articulated cable segments 434A', 434B'. To reverse the direction of the joint joint, the clinician simply reverses the orientation of the joint ring assembly 2460, thereby moving the joint sliding portion 2430 in the distal "DD" direction and bringing the joint sliding portion 2420 closer. Move in the position direction "PD". The articular ring assembly 2460 may be operated in the same manner to apply the desired push-pull motion to the articulated cable segments 454A', 454B'. The friction created between the locking locks 2389, 2399 and the outer circumference of the mounting ball helps to hold the joint drive 2410 in place after the end effector 1000 has been articulated in the desired position. In an alternative exemplary embodiment, the mounting ball is held in place when the locking locks 2389, 2399 are positioned to be received in the corresponding locking recesses of the mounting ball.
0139In the illustrated exemplary embodiment and other embodiments, the elongated shaft assembly 2402 operably interfaces with the handle assembly 2500. An exemplary embodiment of the handle assembly 2500 comprises a pair of handle housing segments 2502, 2504 that are coupled together to form a housing for various drive components and systems as discussed in more detail below. See, for example, Figures 118 and 119. The handle housing segments 2502, 2504 may be connected together by screws, snap mechanisms, adhesives and the like. When connected together, the handle segments 2502, 2504 may form a handle assembly 2500 that includes a pistol grip portion 2506.
0140To facilitate selective rotation of the end effector 1000 around the longitudinal tool axis "LT = LT", the elongated shaft assembly 2402 is interfaced with a first drive system designated as 2510 overall. May be good. The drive system 2510 is rotatably supported and manually actuated so that it can rotate relative to it on the handle assembly 2500 and can move axially between the locking and unlocking positions. Includes rotary nozzle 2512.
0141The surgical instrument 2400 may include a closure system 670 as described above, which applies opening and closing movements to the anvil 1100 of the end effector 1000. However, in this exemplary embodiment, the closure system 670 is actuated by a closure trigger 2530 rotatably mounted on the handle frame assembly 2520 supported within the handle housing segments 2502, 2504. The closure trigger 2530 includes a working portion 2532 that is swivelly mounted on a swivel pin 2531 supported within the handle frame assembly 2520. See Figure 124. Such an exemplary configuration facilitates turning and moving towards and away from the pistol grip portion 2506 of the handle assembly 2500. As seen in FIG. 124, the closure trigger 2530 includes a closure link 2534 linked to a first swivel link and gear assembly 695 by a closure wire 2535. Therefore, by swiveling the closure trigger 2530 towards the pistol grip portion 2506 of the handle assembly 2500 to the working position, the closure link 2534 and the closure wire 2535 allow the first swivel link and gear assembly 695 to become the first closure rod. Move segment 680 distally "DD" to close the anvil.
0142The surgical instrument 2400 may further include a closure trigger locking system 2536 that holds the closure trigger in the working position. In at least one exemplary embodiment, the closure trigger locking system 2536 comprises a closure locking member 2538 swivelably coupled to the handle frame assembly 2520. As seen in FIGS. 125 and 126, the closure locking member 2538 was configured to ride on the arched portion 2537 of the closure link 2532 when the closure trigger 2530 was actuated towards the pistol grip portion 2506. It has a locking arm 2539 formed on it. When the closure trigger 2530 is swiveled to its fully actuated position, the locking arm 2539 falls behind the end of the closure link 2532, preventing the closure trigger 2530 from returning to its non-actuated position. Therefore, the anvil 1100 is locked in its closed position. Clinicians simply disengage the locking arm 2539 at the end of the closing link 2532 so that the closing trigger 2530 returns to its inactive position, thereby allowing the anvil to move from the closed position to the open position. The closure locking member 2538 is swiveled until it allows the closure link 2532 to move to the non-actuated position.
0143The closure trigger 2532 is returned to its inactive position by the closure return system 2540. For example, as seen in FIG. 124, one exemplary embodiment of the closure trigger return system 2540 includes a closure trigger sliding member 2542 linked to the closure link 2534 by the closure trigger yoke 2544. The closure trigger sliding member 2542 is slidably supported within the sliding cavity 2522 of the handle frame assembly 2520. The closing trigger return spring 2546 is positioned within the sliding cavity 2520 to exert an urging force on the closing trigger sliding member 2542. Therefore, when the clinician activates the closure trigger 2530, the closure trigger yoke 2544 moves the closure trigger sliding member 2542 in the distal "DD" direction to compress the closure trigger return spring 2546. When the closure trigger locking system 2536 is disengaged and the closure trigger 2530 is released, the closure trigger return spring 2546 moves the closure trigger sliding member 2542 in the proximal direction "PD", thereby initiating the closure trigger 2530. It is swiveled to the non-operating position of the hour.
0144The surgical instrument 2400 can also use any of the various illustrated drive shaft assemblies described above. In at least one exemplary embodiment, the surgical instrument 2400 uses a second drive system 2550 to apply rotational control motion to the proximal drive shaft assembly 380'. See Figure 128. The second drive system 2550 may include a motor assembly 2552 operably supported within the pistol grip portion 2506. The motor assembly 2552 may be powered by a battery pack 2554 removably attached to the handle assembly 2500, or may be powered by an alternating current source. The second drive gear 2556 is operably coupled to the drive shaft 2555 of the motor assembly 2552. The second drive gear 2556 is supported to mesh and engage with the second rotary driven gear 2558 attached to the proximal drive shaft segment 380'of the drive shaft assembly. In at least one form, for example, the second drive gear 2556 is also axially movable on the motor drive shaft 2555 with respect to the motor assembly 2552 in the direction represented by the arrow "U" in FIG. 128. .. An urging member, such as a coil spring 2560 or a similar member, is positioned between the second drive gear 2556 and the motor housing 2553 and urges the second drive gear 2556 on the motor drive shaft 2555 to a second. Useful for meshing engagement with the first gear segment 2559 on the driven gear 2558 of 2.
0145The second drive system 2550 may further include a firing trigger assembly 2570 mounted movably, eg, swivelly, to the handle frame assembly 2520. In at least one exemplary embodiment, for example, the launch trigger assembly 2570 electrically communicates with the motor assembly 2552 and, when actuated, exerts a first rotational drive motion on the second driven gear 2558 by the motor assembly 2552. Includes a first rotary drive trigger 2527 that works with the corresponding switch / contact (not shown). In addition, the launch trigger assembly 2570 further includes a withdrawal drive trigger 2574 that swivels relative to a first rotational drive trigger. The withdrawal drive trigger 2574 electrically communicates with the motor assembly 2552 and, when activated, operates with a switch / contact (not shown) that applies a second rotational drive motion to the second driven gear 2558 by the motor assembly 2552. Interface connection is possible. The first rotational drive motion results in rotation of the drive shaft assembly and the instrument drive shaft of the end effector, causing the launching member to move distally within the end effector 1000. In contrast, the second rotational drive motion is the opposite of the first rotational drive motion, which ultimately causes the drive shaft assembly and fixture drive shaft to rotate in the rotational direction, thereby firing within the end effector 1000. Proximal movement or withdrawal of the member is provided.
0146The illustrated embodiment is also swivelly attached to the closure trigger actuating portion 2532, and the safety member 2580 is fired by the clinician with a first "safety" position that physically prevents swiveling movement of the firing trigger assembly 2570. Includes a manually actuable safety member 2580 that can be selectively swiveled to and from a second "off" position where the trigger assembly 2570 can be swiveled freely. As seen in FIG. 124, the first recess 2582 is provided in the closing trigger actuating portion 2532, corresponding to the first position of the safety member 2580. When the safety member 2580 is in the first position, the immobilization stop (not shown) on the safety member 2580 is received in the first recess 2582. A second recess 2584 is also provided in the closing trigger actuating portion 2532, corresponding to the second position of the safety member 2580. When the safety member 2580 is in the second position, the anti-movement on the safety member 2580 is received in the second recess 2582.
0147In at least some exemplary embodiments, the surgical instrument 2400 mechanically reverse-rotates with respect to the proximal drive shaft segment 380'if the motor assembly 2552 fails or battery power is lost or interrupted. In addition, a mechanically actuable reversal system, collectively designated as 2590, may be included. Such a mechanical reversing system 2590 is also a drive shaft system operably coupled to the proximal drive shaft segment 380'in a manner that prevents the drive shaft components from rotating backwards solely by the power of the motor, for example. It can be especially useful when the components get stuck or otherwise solidify. In at least one exemplary embodiment, the mechanically actuable reversing system 2590 meshes with the second gear segment 2562 of the second driven gear 2558, a shaft formed on the handle frame assembly 2520. Includes a reversing device 2592 rotatably mounted on the 2524A. See Figure 126. Thus, when the second driven gear 2558 rotates the proximal drive shaft segment 380'of the drive shaft assembly, the reversing device 2592 spins freely on shaft 2524A.
0148In various exemplary forms, the mechanical reversing system 2590 further includes a manually actuable driver 2594 in the form of a lever arm 2596. As seen in FIGS. 129 and 130, the lever arm 2596 includes a yoke portion 2597 having an elongated slot 2598 through it. Shaft 2524A extends through slot 2598A, and a second contralateral shaft 2598B formed on the handle housing assembly 2520 extends through the other elongated slot, against which the lever arm 2596 Sticks so that it can be moved. In addition, the lever arm 2596 has an actuator fin 2597 formed on it capable of engaging and engaging the reversing device 2592. There is a stop or interference that keeps the lever arm 2596 inactive until the clinician exerts substantial force to activate it. This prevents it from being accidentally activated when flipped. In another embodiment, a spring may be used to urge the lever arm into an inactive state. Various exemplary embodiments of the mechanical reversal system 2590 further include a knife withdrawal button 2600, which is movably pivoted within the handle frame assembly 2520. As seen in FIGS. 129 and 130, the knife withdrawal button 2600 includes a disengagement flap 2602 configured to engage the top of the second drive gear 2556. The knife withdrawal button 2600 is urged to the engagement / disengagement position by the knife withdrawal spring 2604. When in the disengagement position, the disengagement flap 2602 is urged to disengage from the second drive gear 2556. Therefore, the second drive gear 2556 and the first gear segment 2559 of the second driven gear 2558 are until the clinician attempts to activate the mechanical reversing system 2590 by pressing down the knife withdrawal button 2600. It is meshing and engaging.
0149When the clinician wants to apply reverse drive motion to the proximal drive shaft segment 380', the clinician pushes down the knife withdrawal button 2600 to second the first gear segment 2559 on the second driven gear 2558. Detach from the drive gear 2556. The clinician then begins applying a swivel ratchet motion to the manually actuable driver 2594, thereby driving the reversing device 2592 on the gear fins 2597 on it. The reversing device 2592 meshes with a second gear segment 2562 on the second driven gear 2558. Continued gradual movement of the manually actuable driver 2594 applies counter-rotational drive motion to the second gear segment 2562 and ultimately to the proximal drive shaft segment 380'. The clinician may continue to move the driver 2594 gradually the number of times required to completely release or reverse the associated end effector component (one or more). Once the desired reverse rotational momentum has been applied to the proximal drive shaft segment 380', the clinician releases the knife withdrawal button 2600 and driver 2594 to their individual start or non-actuated positions, where The fin 2597 disengages from the reverse rotation device 2592 and the second drive gear 2556 meshes again with the first gear segment 2559 on the second driven gear 2558.
0150The surgical instrument 2400 can also be used with the end effector 1000, which includes a rotation transmission device 750 as described in detail above. As mentioned above, when the drive shaft assembly is in the first axial position, the rotational motion applied to it causes the entire end effector 1000 to move the distal longitudinal tool axis "LT-LT" of the articulation 700. Rotate around the center. When the drive shaft assembly is in the second position, the rotational movement applied to it causes the instrument drive shaft to rotate, which ultimately causes the launcher to operate within the end effector 1000.
0151The surgical instrument 2400 is a shift system that selectively shifts the proximal drive shaft segment 380'in the axial direction by moving the shaft gear 376 to engage and disengage with the first rotary driven gear 374. 2610 may be used. For example, the proximal drive shaft segment 380'may be movably supported within the handle frame assembly 2520 so that the proximal drive shaft segment 380'move axially and rotate in it. In at least one exemplary embodiment, the shift system 2610 further includes a shifter yoke 2612, which is slidably supported by the handle frame assembly 2520. See Figures 124 and 127. Since the proximal drive shaft segment 380'has a pair of collars 386 on it (shown in Figures 124 and 128), shifting the shifter yoke 2612 on the handle frame assembly 2520 is a proximal drive shaft segment. Brings 380'axial movement. In at least one form, the shift system 2610 further comprises a shifter button assembly 2614 that operably interfaces with the shifter yoke 2612 and extends through slot 2505 of the handle housing segment 2504 of the handle assembly 2500. See Figures 135 and 136. The shifter spring 2616 is mounted on the handle frame assembly 2520 with engagement of the proximal drive shaft segment 380'. See Figures 127 and 134. The spring 2616 is the first shown in FIG. 135, where the rotation of the drive shaft assembly causes the end effector 1000 to rotate about the longitudinal tool axis "LT-LT" with respect to the joint 700 (shown in FIG. 67). Shifter button assembly 2614 between the axial position of the drive shaft assembly and the second position shown in Figure 136, where rotation of the drive shaft assembly results in axial movement of the launcher within the end effector (shown in Figure 66). Clinically provides audible click and tactile feedback when is slidably positioned Helps to provide to the doctor. Thus, such a configuration allows the clinician to easily slidably position the shifter button assembly 2614 while holding the handle assembly 2500.
0152FIGS. 137-147 show a lockable joint 2700 that, in one exemplary embodiment, is substantially identical to the joint 700 described above, except for the differences discussed below. In one exemplary embodiment, the joint joint 2700 is locked and unlocked by the joint locking system 2710. The articulation joint 2700 includes a proximal socket tube 702 that is attached to the distal end 233 of the distal outer tube portion 231 and defines a proximal ball socket 704 therein. See Figure 137. The proximal ball member 706 attached to the intermediate joint tube segment 712 is movably seated within the proximal ball socket 704 within the proximal socket tube 702. As seen in FIG. 137, the proximal ball member 706 has a central drive passage 708 that allows the distal drive shaft segment 540 to extend through. In addition, the proximal ball member 706 is contained in four articulated passages 710 that facilitate the passage of the distal cable segments 444, 445, 446, 447. As further seen in FIG. 137, the intermediate articular junction tube segment 712 has an intermediate ball socket 714 formed therein. The intermediate ball socket 714 is configured to movably support the end effector ball 722 formed on the end effector connector tube 720. Distal cable segments 444, 445, 446, 447 extend through the cable passage 724 formed within the end effector ball 722 and have a protrusion 726 received within the corresponding passage 728 within the end effector ball 722. Attached there by. Other mounting configurations may be used to mount the distal cable segments 444, 445, 446, 447 to the end effector ball 722.
0153As seen in FIG. 137, one exemplary form of articulated locking system 2710 is a locking wire or locking wire that extends through the distal outer tube portion 231 and the proximal socket tube 702 of the elongated shaft assembly. Includes member 2712. The locking wire 2712 has a proximal end 2720 attached to a transfer disk 2722 operably supported within the handle portion 2500 (represented entirely by a broken line in FIG. 137). For example, the transmission disc 2722 is mounted on a spindle shaft 2724 connected to a boss 2726 formed within the handle 2500. The actuator cable or wire 2730 may be attached to the transmission disk 2722 and manually actuated (ie, pushed or pulled) by the clinician. In other embodiments where the surgical instrument is attached to the robot system, the actuator cable 2730 may be configured to accept control movements from the robot system to actuate the transmission disk 2722.
0154As seen in FIGS. 143 to 146, the locking wire 2712 has a pair of unlocking wedges 2714, 2716 formed at its distal end 2715. The first unlocking wedge 2714 is configured to operably interface with the ends 2742, 2744 of the distal locking ring 2740 axially supported on the intermediate articulated junction 712. In its normal "locking" state, as shown in FIG. 143, the distal locking ring 2740 applies a circumferential locking or squeezing force to the intermediate joint tube 712 to provide an intermediate joint. Press the junction tube 712 against the end effector ball 722 to prevent it from moving within the socket 714. As seen in FIGS. 143 to 146, the ends 2742, 2744 of the distal locking ring 2740 are tapered or conical or configured to accommodate a first unlocking wedge 2714 in between. A V-shaped opening 2746 is defined between them.
0155As further seen in FIGS. 143 to 146, the second locking wedge 2716 should interface with the ends 2752, 2754 of the proximal locking ring 2750 pivotally supported on the proximal socket tube 702. It is composed of. In its normal "locking" state, as shown in FIG. 143, the proximal locking ring 27450 applies a circumferential locking or squeezing force to the proximal socket tube 702 to bring it closer. Press the position socket tube 702 against the proximal ball member 706 to prevent it from moving within the proximal ball socket 704. As seen in FIGS. 143 to 146, the ends 2752, 2754 of the proximal locking ring 2750 are tapered or conical or configured to accommodate a second unlocking wedge 2716 in between. A V-shaped opening 2756 is defined between them.
0156When the articulation joint 2700 is unlocked by the actuation of the articulation locking system 2710, the end effector 1000 selectively activates the distal cable segments 444, 445, 446, 447 in the various manner described above. May be articulated to. The operation of the joint locking system 2710 may be understood with reference to FIGS. 138, 139, and 143 to 146. FIG. 143 shows the positions of the first and second unlock wedges 2714, 2716 with respect to the distal and proximal locking rings 2740, 2750. In that state, the locking ring 2740 prevents the end effector ball 722 from moving in the socket 714, and the locking ring 2750 prevents the proximal ball member 706 from moving in the socket 704. To unlock the articulation 2700, the working cable 2726 is pulled proximally "PD", thereby finally pushing the locking wire 2712 distally "DD" to the position shown in Figure 144. Is done. As can be seen in FIG. 144, the first unlock wedge 2714 moves distally between the ends 2742, 2744 of the distal locking ring 2740 to extend the ring 2740 and is an intermediate joint. The squeezing force applied to the junction tube 712 is relaxed so that the end effector ball 722 can move within the socket 714. Similarly, the second unlock wedge 2716 moves distally between the ends 2752, 2754 of the proximal locking ring 2750 to extend the ring 2750 with respect to the proximal socket tube 712. The squeezing force is relaxed so that the proximal ball member 706 can move within the socket 704. In its unlocked position, the articulation system applies working motion to the distal cable segments 444, 445, 446, 447 as described above, and the end effector 1000, as shown in FIGS. 138 and 139. May be actuated to articulate. For example, FIGS. 143 and 144 show the first and first when the end effector 1000 is articulated to the position shown in FIG. 138. The positions of the locking wedges 2714 and 2716 of 2 are shown. Similarly, FIGS. 145 and 146 show the positions of the first and second locking wedges 2714 and 2716 when the end effector 1000 is articulated to the position shown in FIG. 129. Once the clinician has articulated the end effector into the desired position, the clinician (or robotic system) applies a pushing motion to the working cable to rotate the transmission disk 2722 and the locking wire 2712 in Figure 143. , 145, whereby the locking rings 2740, 2750 can warp to their tightening or locking position and hold the end effector 1000 in that locking position.
0157FIGS. 148-156 show an embodiment of another end effector that, in one exemplary embodiment, is substantially identical to the end effector 1000 except for the differences discussed below. The end effector 2800 includes an anvil assembly 2810 that opens and closes by applying a rotational closing motion. The anvil assembly 2810 is rotatably supported on an elongated channel 2830 for selective movement between open positions (FIGS. 148 and 149) and closed positions (FIGS. 150-153). The elongated channel 2830 may be approximately identical to the elongated channel 1020 described above, with the exception of the differences discussed below.

0159In an exemplary illustrated embodiment, the rotational transmission assembly 2860 extends longitudinally through an elongated shaft assembly with a tool mounting portion (when the end effector 2800 is powered by a robotic system), or Includes a rotary drive shaft 2870 that operably interfaces with the firing trigger of the handle assembly (when the end effector 2800 is manually operated). For those embodiments with joints, a portion of the rotary drive shaft 2870 extending through the joint 700 may comprise any of the flexible drive shaft assemblies disclosed herein. .. If no articulated joint is used, the rotary drive shaft may be rigid. As most notably seen in FIGS. 148 and 149, the rotary drive shaft 2870 has a rotary drive head 2872 formed on or attached to it, the head being a first ring gear formed on it. Has 2874. In addition, the rotary drive head 2872 further comprises a second ring gear 2876 formed on it that selectively meshes with a shifter gear 2882 attached to the rotary drive shaft 2880.
0160The shifter shaft 2880 may include any one of the rotary drive shaft assemblies described above, extending through the elongated shaft assembly and extending through the elongated shaft assembly to the tool mounting portion 300 (when the end effector 2800 is driven by a robot system). ) Or handle assembly (when the end effector is manually operated) and operably interfaced. In each case, the shifter shaft 2800 accepts the longitudinal shift motion, shifting the shifter gear 2882 longitudinally within the rotary drive head 2872 and performing the rotary drive motion, as discussed in more detail below. It is configured to accept and rotate the shifter gear 2882.
0161As further seen in FIGS. 148 and 149, the rotary transmission assembly 2860 further includes a transmission gear assembly 2890 with a body 2892, a portion of which is rotatably supported within the cavity 2872 of the rotary drive head 2872. The body 2892 has a spindle 2894 that rotatably extends through a spindle mounting hole 2838 formed in the bulkhead 2836 of the end effector connector housing 2832. The body 2892 further comprises a shifter ring gear 2896 formed therein that selectively meshes with a shifter gear 2882 on a rotary shifter shaft 2880. The transmission gear 2900 is mounted on a transmission gear spindle 2902 protruding from the body 2892 and is slidably received in the bow slot 2840 of the bulkhead 2836. See Figures 155 and 156. The transmission gear 2900 meshes with a first ring gear 2874 formed within the rotary drive head 2872. As seen in FIGS. 153 to 156, the arcuate slot 2840 has a centrally located flexible lock 2842 that projects inward. The stop 2842 is formed on the web 2844 formed by the stop relief slot 2846, which is formed adjacent to the bow slot 2840, as shown in FIG. 155.
0162The rotary closure shaft 2910 has a bearing portion 2912 rotatably supported through the corresponding opening of the bulkhead 2836. The rotary closure shaft 2910 further comprises a closure drive gear 2914 configured to selectively mesh with the transmission gear 2900. The instrument drive shaft 1300 also has an instrument drive gear 1302 configured to selectively mesh and engage the transmission gear 2900.
0163The operation of the end effector 2800 will be described below with reference to FIGS. 148 to 155. Figures 148 and 149 show the end effector 2800 with the anvil assembly 2810 in the open position. To move the anvil assembly 2810 to the closed position shown in FIG. 150, the shifter shaft 2880 is arranged such that the shifter gear 2882 meshes with the shifter ring gear 2896 in the body 2892. By rotating the shifter shaft 2880, the body 2892 may be rotated so that the transmission gear 2900 meshes with the closing drive gear 2914 on the closing shaft 2910. See Figure 153. When in that position, the locking movement stop 2842 holds the transmission gear spindle 2902 in that position. After that, the rotary drive shaft 2870 is rotated to apply a rotary motion to the transmission gear 2900, whereby the closed shaft 2910 is finally rotated. When the closure shaft 2910 is rotated, the rotating spindle portion 2916 engaged with the closure pin 2818 on the anvil assembly 2810 moves the anvil assembly 2810 to the proximal side, causing the anvil assembly 2810 to anvil the launch member 1200'. Swivel on swivel pin 1201'. This action causes the anvil assembly 2810 to rotate to the closed position shown in FIG. 150. When the clinician wants to drive the launcher 1200'downward and distally to the elongated channel 2830, the shifter shaft 2880 is rotated again to rotate the transmission gear spindle 2902 to the position shown in Figure 154. Again, the locking movement stop 2842 holds the transmission gear spindle 2902 in that position. After that, the rotary drive shaft 2870 is rotated to apply a rotary motion to the transmission gear 1302 on the instrument drive shaft 1300. The launch member 1200'is driven in the distal direction "DD" by rotating the instrument drive shaft 1300 in one direction. The launch member 1200'is withdrawn in the proximal direction "PD" as the instrument drive shaft 1300 rotates in the opposite direction. Therefore, the launcher 1200'has an elongated channel 2 In those applications configured to cut and fire staples in staple cartridges mounted on the 830, the launcher 1200'is driven to its most distal position within the elongated channel 2830 and then rotationally driven. The rotational drive motion applied to the instrument drive shaft 1300 by the shaft assembly 2870 is reversed and the launch member 1200'is withdrawn back to its starting position as shown in FIG. 150. To release the target tissue from the end effector 2800, the clinician re-rotates the shifter shaft 2800 to re-engage the transmission gear 2900 with the drive gear 2914 on the closed drive shaft 2910. The rotary drive shaft 2870 then applies a counter-rotational motion to the transmission gear 2900, which causes the closed drive shaft 2910 to rotate the drive spindle 2916, which causes the anvil assembly 2810 to move distally, as shown in FIGS. 148 and 149. Turn to the open position. When the clinician wants to rotate the entire end effector 2800 around the longitudinal tool axis "LT-LT", the shifter axis is shifted longitudinally and the shifter gear 2882 rotates, as shown in Figure 152. It meshes and engages with the second ring gear 2876 on the drive head 2872 and the shifter ring gear 2896 on the transmission gear body 2892 at the same time. Then, by rotating the rotation drive shaft 2880, the end effector 2800 rotates with respect to the end effector connector tube 720 about the longitudinal tool axis "LT-LT". Re-engage with drive gear 2914 on chain drive shaft 2910. The rotary drive shaft 2870 then applies a counter-rotational motion to the transmission gear 2900, which causes the closed drive shaft 2910 to rotate the drive spindle 2916, which causes the anvil assembly 2810 to move distally, as shown in FIGS. 148 and 149. Turn to the open position. When the clinician wants to rotate the entire end effector 2800 around the longitudinal tool axis "LT-LT", the shifter axis is shifted longitudinally and the shifter gear 2882 rotates, as shown in Figure 152. It meshes and engages with the second ring gear 2876 on the drive head 2872 and the shifter ring gear 2896 on the transmission gear body 2892 at the same time. Then, by rotating the rotation drive shaft 2880, the end effector 2800 rotates with respect to the end effector connector tube 720 about the longitudinal tool axis "LT-LT". Re-engage with drive gear 2914 on chain drive shaft 2910. The rotary drive shaft 2870 then applies a counter-rotational motion to the transmission gear 2900, which causes the closed drive shaft 2910 to rotate the drive spindle 2916, which causes the anvil assembly 2810 to move distally, as shown in FIGS. 148 and 149. Turn to the open position. When the clinician wants to rotate the entire end effector 2800 around the longitudinal tool axis "LT-LT", the shifter axis is shifted longitudinally and the shifter gear 2882 rotates, as shown in Figure 152. It meshes and engages with the second ring gear 2876 on the drive head 2872 and the shifter ring gear 2896 on the transmission gear body 2892 at the same time. Then, by rotating the rotation drive shaft 2880, the end effector 2800 rotates with respect to the end effector connector tube 720 about the longitudinal tool axis "LT-LT".
0164Figures 157-170 show another end effector embodiment 3000 that opens and closes the anvil assembly 3010 using a pull-type motion. The anvil assembly 3010 is movably supported on the elongated channel 3030 for selective movement between the open position (FIGS. 168 and 169) and the closed position (FIGS. 157, 160, and 170). The elongated channel 3030 may be approximately identical to the elongated channel 1020 described above, with the exception of the differences discussed below. The elongated channel 3030 may be connected to the end effector drive housing 1010 as described above. The end effector drive housing 1010 may also be connected to the end effector connector tube 734 by a ring bearing 734 as described above.

The lower surface of the anvil assembly 2810 further has an anvil open notch 3016 formed over it so as to swivelly engage with the upper fins 1208 on the launching member 3100. See Figure 168. The launching member 3100 may be substantially identical to the launching member 1200 described above, except for the differences mentioned. In the illustrated embodiment, the end effector 3000 further comprises an anvil spring 3050 configured to urge the anvil trunnion 3012. One form of the anvil spring 3050 is shown in Figure 159. As can be seen in the drawing, the anvil spring 3050 is made from metal wire and is configured to rest on the anvil trunnion 3012, with the anvil trunnions being accepted within their individual trunnion slots 3032. It may have opposed spring arms 3052. In addition, as further seen in Figure 159, the anvil spring 3050 was adapted to movably support the corresponding spring pin 3034 formed on the elongated channel 3030 formed in it, 2 It has two mounting loops 3054. See Figure 158. As discussed in more detail below, the anvil spring 3050 is configured to swing on the spring pin 3034 within the elongated channel 3030. As most prominently seen in FIG. 158, a portion 3035 of each side wall of the elongated channel is recessed to provide play for the movement of the anvil spring 3050.
0166As seen in FIGS. 157 and 160-170, the end effector 3000 further includes a closed tube 3060 movably supported on the elongated channel 3030 for selective longitudinal movement. To facilitate longitudinal movement of the closure tube 3060, the embodiments shown in FIGS. 157 and 160-170 are swivelably pinned or otherwise attached to the closure tube 3030, a link mechanism arm. Includes closure solenoid 3070 linked to closure tube 3060 by 3072. Activating the solenoid drives the linkage arm 3072 distally, driving the closure tube 3060 distally at the end of the elongated channel 3030. As the closure tube 3060 moves distally, the anvil assembly 3010 swivels to the closure position. In an alternative embodiment, the solenoid may include an annular solenoid mounted at the distal end of the end effector drive housing 1010. The closed tube is made of a metallic material that can be magnetically attracted and repelled by an annular solenoid to result in longitudinal movement of the closed tube.
0167In at least one form, the end effector 3060 further comprises a proprietary anvil locking system 3080 that locks and holds the anvil assembly 3010 in place when closed on the target tissue. In one form, as seen in FIG. 157, the anvil locking system 3080 traverses the elongated channel 3030 so that the ends are accepted within the corresponding locking bar window 3036 formed in the elongated channel 3030. Includes anvil locking bar 3082, which extends across the direction. See Figure 158. Referring to FIG. 161, when the closing tube 3060 is in its most distal "closed" position, the end of the locking bar 3082 projects laterally outward through the locking bar window 3036 and the closing tube 3060. It extends beyond the proximal end of the and prevents it from moving proximally and out of place. The locking bar 3082 is configured to engage the solenoid contact 3076 supported within the end effector drive housing 1010. Solenoid contact 3076 is laid out in the control system that controls solenoid 3070. The control system includes, in any case, a power source supplied by either a battery or other power source in the robot system or handle assembly.
0168The launch member 3100 is rotatably supported on an instrument drive shaft 1300, rotatably supported within an elongated channel 2830 configured to support a surgical staple cartridge (not shown) inside. The instrument drive shaft 1300 is rotatably supported within the bearing sleeve 2834 formed on the end effector connector housing 2832 formed on it and operably interfaced with the rotation transmission device 750 as described above. , Has bearing segment 1304. Rotation of the fixture drive shaft 1300 in one direction drives the launcher 3100 distally through an elongated channel 3030, and rotation of the fixture drive shaft 1300 in the opposite direction brings the launcher 1200'' closer. Withdrawn in the direction of "PD". As seen in FIGS. 157 and 160-170, the launching member 3100 has an actuating bar 3102 configured to engage the locking bar 3082, as discussed in more detail below.
0169The anvil locking system 3080 is anvil when the closure tube 3060 has moved to its most distal position and the distal end of the closure tube 3060 is in contact with the anvil ledge 3013 formed on the anvil assembly 3010. Includes an anvil tension assembly 3090, which selectively pulls to engage the closure tube 3060 in an interrupt-locking manner. In one form, the anvil tension assembly 3090 is attached to the proximal end of the anvil assembly 3010 and in any case projects proximally through the elongated shaft assembly to the tool mount or handle assembly. Includes a pair of anvil tension cables 3092. The tension cable 3092 may be attached to an actuator mechanism on the handle assembly or connected to one of the drive systems on the tool mount that is configured to tension the cable 3092.
0170The operation of the end effector 3000 will be described below. Figures 168 and 169 show the anvil assembly 3010 in the open position. FIG. 168 shows a firing member 3100 in the most recent position, where a new staple cartridge (not shown) may be mounted within the elongated channel 3030. The closed tube 3060 is also in its most recent non-operating position. Also, as seen in FIG. 167, when the launching member 3100 is in its most recent position, the actuating bar 3102 urges the locking bar to engage the solenoid contact 3076, thereby causing the solenoid to follow. Can be started for the closing procedure of. Therefore, to initiate the closure process, the rotary drive shaft 752 is actuated to move the launching member 3100 to its starting position shown in FIG. 169. When in that position, the actuating bar 3102 is moving proximally so that the locking bar 3082 can move and disengage from the solenoid contact 3076, thereby powering the solenoid. When supplied to the control circuit, the solenoid link 3072 is extended. Control power is then applied to the solenoid 3070, either automatically or through a switch or other control mechanism within the handle assembly, whereby the distal end of the closure tube 3060 contacts the ledge 3013 on the anvil assembly 3010. Until, the closure tube 3060 moves distally and the anvil assembly swivels and closes on the launch member 1200'', as shown in FIG. 162. As seen in the drawing, the locking bar 3082 is positioned to prevent the closure tube 3060 from moving in the proximal direction. When in that position, the clinician then tensions the tension cable 3092 and pulls the proximal end of the anvil assembly 3010 to interrupt engage with the closure tube 3060, locking the anvil assembly 3010 in the closed position. To do. The launch member 1200'' may then be driven distally through the tightened tissue within the end effector 3000. Once the launch process is complete. Equipment The drive shaft rotates in the opposite direction, the launching member 3100 is returned to its starting position, the actuating bar 3102 again contacts the locking bar 3082, bends it into contact with the solenoid contact 3076, and engages. The end of the stop bar 3082 is pulled into the window 3036 of the elongated channel 3030. When in that position, when the solenoid control system is powered, the solenoid 3070 retracts the closed tube 3060 proximally to its starting or opening position shown in FIGS. 167 and 168. When the closure tube 3060 moves proximally and disengages from the anvil assembly 3010, the anvil spring 3050 applies urging force to the anvil trunnion 3012 to open the anvil assembly in the open position shown in Figure 168. To urge.
