Various exemplary devices and methods are provided for performing laparoscopic and minimally invasive surgical procedures. However, it is readily appreciated by the reader that the various methods and devices disclosed herein can be used in many surgical procedures and applications, including those associated with, for example, open surgical procedures. Will. By reading "forms for carrying out the invention" herein, the reader may read that the various instruments disclosed herein are incisions or punctures formed in the tissue, eg, through a natural opening. You will further understand that it can be inserted into the body in any way, such as through a hole. The working part or end effector part of these instruments can be inserted directly into the patient's body or through an access device with a passage of action capable of advancing the end effector and elongated shaft of the surgical instrument. You can also do it.
The surgical staple system can include a shaft and an end effector extending from the shaft. The end effector comprises a first jaw and a second jaw. The first jaw comprises a staple cartridge. The staple cartridge is removable from the first jaw and is removable from the first jaw, but the staple cartridge is not removable from the first jaw, or at least not easily replaceable. Other embodiments are also conceivable. The second jaw comprises an anvil configured to deform the staple ejected from the staple cartridge. The second jaw is pivotable with respect to the first jaw about the closed axis, while the first jaw is pivotable with respect to the second jaw, the other Embodiments are also conceived. The surgical staple fastening system further comprises a joint that is configured to allow the end effector to rotate, i.e., move with respect to the shaft. The end effector is rotatable about a range of motion that extends through the joint. Other embodiments that do not include joints are also conceivable.
The staple cartridge includes a cartridge body. The cartridge body includes a proximal end, a distal end, and a deck extending between the proximal and distal ends. In use, the staple cartridge is positioned on the first side of the tissue to be stapled and the anvil is located on the second side of the tissue. The anvil is moved towards the staple cartridge to compress and clamp the tissue against the deck. Subsequently, staples detachably stored in the cartridge body can be subsequently deployed in the tissue. The cartridge body includes a staple cavity defined therein, and the staples are detachably stored in the staple cavity. Staple cavities are arranged in six longitudinal rows. The three rows of staple cavities are located on the first side of the longitudinal slot and the three rows of staple cavities are located on the second side of the longitudinal slot. Staple cavities and other arrangements of staples are also possible.
The staples are supported by a staple driver inside the cartridge body. The driver can move between the first, i.e., unlaunched position and the second, i.e., the firing position, which ejects the staples from the staple cavity. The driver includes an elastic member that is held within the cartridge body by a retainer that extends around the bottom of the cartridge body and is configured to grip the cartridge body and hold the holder against the cartridge body. .. The driver can move between their unfired position and their fired position by a thread. The thread is mobile between the proximal position adjacent to the proximal end and the distal position adjacent to the distal end. The thread slides under the driver and has multiple ramps configured to lift the driver, on which the staples are supported and towards the anvil.
In addition to the above, the thread is moved distally by the launcher. The launcher is configured to contact the thread and push the thread towards the distal end. In one or more alternative embodiments, the thread is attached to the launcher. Longitudinal slots defined within the cartridge body are configured to receive launching members. The anvil also includes a slot configured to receive the launching member. The launching member further comprises a first cam that engages the first jaw and a second cam that engages the second jaw. As the launcher is advanced distally, the first and second cams can control the distance between the deck of the staple cartridge and the anvil, i.e. the tissue gap. Other embodiments are also conceivable in which the firing member has only one cam member or no cam member. Such embodiments may include other suitable means for holding the first jaw and the second jaw in place. In any case, the launcher also comprises a knife configured to make an incision in the tissue trapped between the staple cartridge and the anvil. It is desirable that the knife be positioned at least partially proximal to the slope so that the staples are ejected forward of the knife.
Figure 1 shows the end effector 100 of a surgical stapling system. The end effector 100 includes a frame 190, a cartridge jaw 110, and an anvil 120. The cartridge jaw 110 is fixed and extends from the frame 190. The anvil 120 is movable relative to the cartridge jaw 110 between an open or unclamped position and a closed or clamped position (FIG. 1). In an alternative embodiment, the cartridge jaw 110 is movable relative to the anvil 120 between an open or unclamped position and a closed or clamped position. In at least one such embodiment, the anvil 120 is fixed and extends from the frame 190.
The cartridge jaw 110 is configured to receive a staple cartridge such as, for example, a staple cartridge 130. Referring to FIG. 2, the staple cartridge 130 includes a cartridge body 132. The cartridge body 132 comprises a deck 133 configured to support the patient's tissue, a longitudinal slot 135, and a row of six longitudinal staple cavities 134 defined within the deck. The longitudinal slot 135 is configured to receive a launching member, such as a launching member 270 (FIG. 12). Each of the staple cavities 134 is configured to receive and detachably store the staple 140 (FIG. 3) in it. The staple cartridge 130 further comprises a staple driver, such as the staple driver 180 (FIG. 3A), which is configured to push the staple 140 out of the staple cavity 134. With reference to FIGS. 3 and 3A, each staple driver 180 comprises a pedestal 182 configured to support and / or engage the base or crown 142 of the staple 140. Other staple drivers are also conceivable in which the driver has, for example, two pedestals, three pedestals, or four pedestals for supporting and engaging two or more staples.
In addition to the above, the staple cartridge 130 further comprises a thread configured to engage the staple driver 180. More specifically, the thread comprises one or more lamps, the lamp engaging with one or more cams defined on the staple driver 180, for example cam 185, and the thread is also a staple cartridge 130. It is configured to lift the staple driver 180 and staple 140 within the staple cavity 134 as it is moved distally through. The launching member 270 is configured to move the thread distally from the proximal unlaunched position to the distal firing position during the staple firing stroke. In at least one case, each staple 140 is fully positioned below deck 133 of the cartridge body 132 when the staple 140 is in the unfired position. In such cases, the staple legs 144 of the staple 140 do not extend beyond the deck 133 when the staple 140 is in the unfired position. In use, the tip 146 of the staple leg 144 appears above the deck 133 when the staple 140 is fired. Such a configuration can reduce the likelihood that the staple 140 will get caught in the patient's tissue when the staple cartridge 130 is moved relative to the tissue.
In various other cases, in addition to the above, the tip 146 of the staple leg 144 extends beyond the deck 133 when the staple 140 is in the unlaunched position. Primarily with reference to FIG. 2, the cartridge body 132 further comprises a protrusion 136 extending above the deck 133, which protrusion at least partially surrounds the tip 146 when the staple 140 is in the unlaunched position. It is configured as follows. The length of the staple leg 144 is chosen so that the tip 146 is located below the top surface of the protrusion 136 when the staple 140 is in the unlaunched position. The protrusion 136 is also configured to guide the staple leg 144 as the staple 140 is ejected from the staple cavity 134. In some respects, the protrusion 136 extends the staple cavity 134 above the deck 133. Such a configuration allows the use of longer or higher staples while at the same time protecting the staples even though they extend above deck 133.
In addition to the above, the staple 140 is made up of wires. The wire has a round, or at least substantially round, cross section. However, any suitable cross section can be used. For example, a square cross section and / or a cross section with at least one flat side may be used. The wire is made of a metal such as titanium and / or stainless steel. Nevertheless, the wire can be made of any suitable material, such as plastic.
Each of the staples 140 is composed of a bent wire formed to form a crown portion 142 and a staple portion 144 of the staples 140. As described in more detail below, the anvil 120 is configured to deform the staple 140 between the unlaunched configuration (FIG. 3) and the fired configuration. As shown in FIG. 3, the legs 144 of the staple 140 are not parallel to each other when the staple 140 is in the unfired configuration. In such an example, the staple 140 has a substantially V-shaped configuration when the staple 140 is in the unlaunched configuration. In certain embodiments, staples with parallel or at least substantially parallel legs when in an unlaunched configuration may be utilized. In such an example, the staples have a substantially U-shaped configuration when the staples are in the unfired configuration.
Referring again to FIG. 2, the staple cartridge 130 further comprises a retainer 160 attached to the cartridge body 132. The retainer 160 extends at least partially around the bottom of the cartridge 132 and is configured to prevent the staple 140, staple driver 180, and / or thread from falling from the bottom of the cartridge body 132. The retainer 160 is configured to engage the cartridge body 132 in a snap-fitting manner, however, the retainer 160 may be attached to the cartridge body 132 in any suitable manner. Further, the retainer 160 is configured to engage with the cartridge jaw 110 in a snap-fitting manner to releasably hold the staple cartridge 130 within the cartridge jaw 110. That is, the staple cartridge 130 can be releasably held in the cartridge jaw 110 in any suitable manner.
In addition to the above, the end effector 100 is also configured to be used with staple cartridges other than the staple cartridge 130, such as the staple cartridge 230 (FIG. 4). In other words, the staple cartridge 230 may be used with the end effector 100, for example, in place of the staple cartridge 130. In one example, the end effector 100 could be used with the staple cartridge 130, and after the staple cartridge 130 was at least partially fired, the staple cartridge 130 was removed from the first jaw 110. It can then be replaced with an unfired staple cartridge 230. In various examples, the surgeon may selectively and interchangeably use one or more staple cartridges 130 and one or more staple cartridges 230 in any suitable order.
Referring to FIG. 4, the staple cartridge 230 includes a cartridge body 232 and a retainer 260 attached to the cartridge body 232. The retainer 260 is similar to the retainer 160 in many respects. The retainer 260 is configured to engage the cartridge body 232 in a snap-fitting manner, however, the retainer 260 may be attached to the cartridge body 232 in any suitable manner. Further, the retainer 260 is configured to engage with the cartridge jaw 110 in a snap-fitting manner to releasably hold the staple cartridge 230 within the cartridge jaw 110. That is, the staple cartridge 230 can be releasably held in the cartridge jaw 110 in any suitable manner.
The cartridge body 232 comprises a deck 233 configured to support the patient's tissue, a longitudinal slot 135, and a row of longitudinally extending staple cavities defined within the deck. Deck 233 comprises a first portion on the first side of the longitudinal slot 135 and a second portion on the second side of the longitudinal slot 135. The first and second parts of deck 233 are, respectively, a row of first or inner longitudinal staple cavities, a second or middle row of longitudinal staple cavities, and a third or third. It comprises a row of staple cavities extending outward longitudinally. The first part of deck 233 consists of a first longitudinal row containing staple cavities 234a, a second longitudinal row containing staple cavities 234a, and a third including staple cavities 234a'. It has a row extending in the longitudinal direction of the. The second part of deck 233 includes a first longitudinal row containing staple cavities 234a', a second longitudinal row containing staple cavities 234a', and a second including staple cavities 234. It has 3 rows extending in the longitudinal direction.
In addition to the above, staple cavities 234a and staple cavities 234a'are similar in many respects, except that they are mirror images of each other. The staple cavity 234a may be referred to as the "left" staple cavity and the staple cavity 234a'may be referred to as the "right" staple cavity. Needless to say, left and right are a matter of perspective, and different nomenclatures and vice versa can be used. In addition, any suitable configuration of the left staple cavity 234a and the right staple cavity 234a'can be utilized.
With reference to FIGS. 4, 5, and 14, the staples 240 are detachably housed in each staple cavity 234a. Referring to FIG. 13, the staples 240'are detachably housed in each staple cavity 234a'. Staple 240 and Staple 240'are similar in many respects, except that they are mirror images of each other. Consistent with the nomenclature used above, staple 240 is a "left" staple and staple 240'is a "right" staple.
Referring again to FIG. 4, the second part of deck 233 is a mirror image of the first part of deck 233. With such a configuration, when the launching member 270 moves distally through the longitudinal slot 135 during the launching stroke, it is formed by a tissue cutting line, i.e., a cutting edge 272 defined on the launching member 270. A symmetric staple line is generated for the longitudinal cut. In other embodiments, the second part of deck 233 is not a mirror image of the first part of deck 233. Such a configuration produces staple lines that are asymmetric with respect to the cutting line in the tissue to be tapered.
Primarily with reference to FIGS. 7-10, the staple 240 comprises a crown 242, a proximal staple leg 244p connected to the crown 242, and a distal leg 244d connected to the crown 242. There is. More specifically, the staple 240 has a proximal connector 248p that connects the proximal staple leg 244p to the crown 242 and a distal connector 248d that connects the distal staple leg 244d to the crown 242. I have. The proximal connector 248p is integrally formed with the staple leg 244p and the crown 242, and similarly, the distal connector 248d is integrally formed with the distal staple leg 244d and the crown 242. .. The staple 240 further comprises a driver 246 that is integrally formed with and extends from the crown portion 242. The driver 246 comprises a cam surface 245 defined on it, which cam surface is directly engaged by the thread 250 of the staple cartridge 230 during the staple firing stroke, as shown in FIG. It is configured as follows.
As can be seen in FIGS. 7-10, the crown portion 242 and the driver 246 collectively define a height higher than that of the proximal connector 248p and / or the distal connector 248d. Further, the collective height of the crown 242 and the driver 246 defines dimensions greater than any cross-sectional width of the staple legs 244p and 244d.
Similarly, as can be seen in FIGS. 7-10, the proximal leg 244p, the proximal connector 248p, the distal leg 244d, and the distal connector 244d do not extend below the driver 246. In other words, the driver 246 constitutes the bottom of the staple 240. Further, the entire cam surface 245 is below the proximal leg 244p, the proximal connector 248p, the distal leg 244d, and the distal connector 244d. Such a configuration helps ensure that the thread 250 contacts the driver 246 of the staple 240 and not the other parts of the staple 240.
In addition to the above, referring again to FIG. 13, the staple 240'has a crown 242', a proximal leg 244p' connected to the crown 242', and a distal leg connected to the crown 242'. It includes a portion 244d'and a driver 246' that is integrally formed with and extends from the crown portion 242'. Driver 246'is provided with a cam surface 245' defined on it, which cam surface is configured to be directly engaged by threads 250 during the staple firing stroke. Unless otherwise stated, the teachings presented herein with respect to Staple 240 are also applicable to Staple 240'. For brevity, discussions dealing with these adaptations may not be specifically stated herein.
Each staple 240 is composed of an integral piece of metal such as titanium and / or stainless steel. Other materials such as plastic may also be used. In various examples, the staple 240 is punched out of one or more sheets of material. In at least one example, a continuous flat strip of metal stock is a progressive die. Supplied to die), the progressive die punches or punches a strip of material, pulling the crown 242 away from the plane with the staple legs 244p and 244d or pushing it away. Instead, the staple legs 244p and 244d are pulled away from or pushed away from the plane along with the crown 242. In various examples, the progressive die is also configured to form one or more rounded edges on the staple 240, for example on the staple legs 244p and 244d. The progressive die is also configured to cast the tip 246 of the staple legs 244p and 244d in certain examples to remove any excess material from the strip of material. Each of these molding steps can occur at one or more stations within the feed die and / or within the same molding station within the feed die, but the configuration is ultimately, eg, continuous bandolier. It will produce a piece of staple 240 attached to (bandolier). Staple 240 is removed from the band rear and then inserted into staple cavity 234. In a particular example, a piece of staple 240 is loaded into the loading block, where the bandria is then removed from staple 240. Then, using the loading block, the staple 240 is inserted into the staple cavity 234a of the cartridge body 232. In at least one example, the loading block is also configured to accept the staples 240'so that the staples 240 and 240' are simultaneously loaded into the cartridge body 232.
In addition to the above, primarily with reference to FIG. 7, the driver 246 of each staple 240 is attached to the band rear at a connection point 249 defined distal to the driver 246. Such a configuration reduces, for example, the possibility that burrs or tags extend downward from the driver 246 and impede longitudinal travel of the thread 250. That is, any suitable mounting point may be utilized to hold the staple 240 in the band rear. In addition to or instead, wire burning, or operation of an electric discharge machine (EDM), and / or any other suitable manufacturing process may be utilized to form the staple 240. .. Further, staple 240'can be manufactured, among other things, using any of the methods described herein.
Referring to FIGS. 8 and 9, the proximal staple leg 244p and the distal staple leg 244d of the staple 240 define the staple leg plane 241s. In addition to the above, the proximal staple leg 244p of the staple 240 is located proximal to the distal staple leg 244d when the staple 240 is located within the staple cavity 234a. In addition, the proximal staple leg 244p and the distal staple leg 244d of the staple 240 are aligned with the firing axis. This firing axis also aligns with the staple legs 244p and 244d of the other staples 240 when the staples 240 are located within a row of staple cavities 234a extending longitudinally. As a result, the staple leg planes 241s of the staples 240 in the row of staple cavities 234a extending longitudinally are aligned with each other, or at least substantially aligned with each other. It should be understood that the staple legs 244p and 244d have a certain width or thickness and the staple leg planes 241s may include that width of the staple legs 244p and / or 244d.
In addition to the above, referring to FIGS. 4 and 6, the left staple 240 housed in a row of first inner longitudinal staple cavities is such that the staple leg plane 241s of the staple 240 is driven by the drive plane 241c. Is also detachably stored in the longitudinal slot 135 so that it is closer to it. Correspondingly, with reference to FIGS. 4 and 6, the right staple 240'stored in the second inner row of longitudinally extending staple cavities also has the staple leg plane 241s of the staple 240'. It is detachably housed therein so as to be closer to the longitudinal slot 135 than the drive plane 241c. Similarly, the left staple 240 housed in a row of first intermediate longitudinal staple cavities is such that the staple leg plane 241s of the staple 240 is closer to the longitudinal slot 135 than the drive plane 241c. It is detachably stored in it. Similarly, for the right side staple 240'stored in a row of second intermediate longitudinal staple cavities, the staple leg plane 241s of the staple 240' is closer to the longitudinal slot 135 than the drive plane 241c. As such, it is detachably stored in it. On the other hand, referring to FIGS. 4 and 6, the right side staple 240'stored in the row of first outer longitudinal staple cavities has the drive plane 241c of the staple 240' from the staple leg plane 241s. Is also detachably stored in the longitudinal slot 135 so that it is closer to it. Similarly, the left staple 240 housed in a row of second outer longitudinal staple cavities also has the drive plane 241c of the staple 240 closer to the longitudinal slot 135 than the staple leg plane 241s. In addition, it is detachably stored in it.
As described in more detail below, the staple legs 244p, 244d of the staple 240 include a tissue-tightened or clamped portion of the staple 240, which is the staple leg 244p, 244d of the staple 240. Is configured to trap the patient's tissue within staple 240 when deformed relative to the anvil 120. In various examples, the proximal staple leg 244p and the distal staple leg 244d are formed within the staple leg plane 241s. In another example, however, one or both of the staple legs 244p and 244d can be deformed out of the staple leg plane 241s.
In addition to the above, as shown in FIG. 7, the proximal staple leg 244p of the staple 240 is parallel to, or at least substantially substantially, parallel to the staple leg 244d when the staple 240 is in the unlaunched configuration. It is parallel. As a result, the staple legs 244p, 244d and crown 242 of the staple 240 form a substantially U-shaped configuration when the staple 240 is in the unlaunched position. In such a configuration, the upward movement of the staple legs 244p and 244d as the staple 240 is ejected from the staple cavity 234a may be easier to control than in other configurations. In various alternative embodiments, with reference to FIG. 14, the proximal staple leg 244p and the distal staple leg 244d of the staple 240 are outward and / or non-parallel to each other. Extend. In at least one such example, the staple legs 244p, 244d and crown 242 of the staple 240 form a substantially V-shaped configuration when the staple 240 is in the unlaunched position. In such a configuration, the staple legs 244p and 244d of the staple 240 are in contact with the side wall of the staple cavity 234a, which can elastically hold the staple 240 in the staple cavity 234a, and elastically inward by the side wall. Can be urged.
In addition to the above, the retainer 260 extends at least partially around the bottom of the cartridge 232 to prevent the staple 240, staple 240', and / or thread 250 from falling from the bottom of the cartridge body 232. It is configured in.
Primarily with reference to FIG. 10, the staple 240 driver 246 comprises a staple 240 drive portion. The longitudinal ramp 255 of the thread 250 is configured to sequentially engage the driver 246 of the staple 240 and slide under the driver to lift the staple 240 upward in the staple cavity 234a towards the anvil 120. ing. The cam surface 245 of each staple 240 is defined on the proximal side of the driver 246 and includes the point where the thread 250 initiates contact with the staple 240. Each driver 246 of the staple 240 is defined within the drive plane 241c, which is aligned with, or at least substantially aligned with, the longitudinal ramp 255. The cam surface 245 is also defined within the drive plane 241c. It should be appreciated that the cam surface 245 and / or the driver 246 has a certain width or thickness and the drive plane 241c may include that width of the cam surface 245 and / or the driver 246.
Referring again to FIGS. 8 and 9, connectors 248p and 248p separate the staple legs 244p and 244d from the staple 240 crown 242, respectively. As shown in FIGS. 8 and 9, the drive plane 241c of the staple 240 is laterally displaced from the staple leg plane 241s of the staple 240. Similarly, as shown in FIGS. 8 and 9, the drive plane 241c of the staple 240 is parallel to, or at least substantially parallel to, the staple leg plane 241s of the staple 240. In such an example, the drive planes 241c of a row of staples 240 extending longitudinally are aligned with each other along the longitudinal drive axis. The longitudinal drive axis is parallel to and adjacent to the longitudinal launch axis aligned with the staple leg plane 241s described above.
Referring again to FIGS. 8-10, the longitudinal ramp 255 does not engage the proximal connector 248p or the distal connector of the staple 240. Similarly, the longitudinal ramp 255 does not engage the staple legs 244p and 244d of the staple 240. Furthermore, no portion of the thread 250 engages with the proximal connector 248p, proximal staple leg 244p, distal connector 248d, and distal staple leg 244d of the staple 240. Instead, the longitudinal ramp 255 engages directly with the cam surface 245 of the staple 240 as the thread 250 is moved distally during the firing stroke. When the thread 250 is moved distally, the longitudinal ramp 255 slides below the cam surface 245, continuing to move the staple 240 to the anvil 120 between the unlaunched position (Figure 11) and the fired position (Figure 12). Lift upwards toward you. In other words, the staple 240 slides the longitudinal lamp 255 upward in the staple cavity 234a towards the firing position, as shown in FIG.
In addition to the above, mainly referring to FIG. 10, the drive surface 245 of the staple 240 does not extend to the proximal connector 248p. The driver 246 includes a notch or relief 247 that separates the drive surface 245 from the proximal connector 248p. In various examples, the notch 247 is defined within the drive plane 241c. In at least one example, the notch 247 extends to the proximal connector 248p. The notch 247 ensures that the thread 250 contacts the driver 246 of the staple 240, i.e., within the drive plane 241c of the staple 240, and not the proximal connector 248p and / or the proximal leg 244p. It is configured. The notch 247 also creates a clear depiction between the driver 246 and the proximal connector 248p so that the cam surface 245 is not twisted out of the drive plane 241c. Further, the notch 247 separates the drive plane 241c from the vertical plane including the proximal staple leg 244p.
Similar to the above, the drive plane 245 does not extend to the distal connector 248d.
In addition to the above, the drive plane 245 of the staple 240 extends at an angle that matches, or at least substantially matches, the angle of the longitudinal ramp 255 of the thread 250. That is, any suitable angle can be used.
In at least one example, in addition to the above, each staple 240 is fully positioned below deck 233 of the cartridge body 232 when the staple 240 is in the unfired position. In such an example, the staple leg 244 of the staple 240 does not extend beyond the deck 233 when the staple 240 is in the unfired position. In use, the tip 246 of the staple leg 244 appears above the deck 233 when the staple 240 is being fired. Such a configuration can reduce the possibility that the staple 240 will get caught in the patient's tissue when the staple cartridge 230 is moved relative to the tissue.
In various examples, in addition to the above, the tip 246 of the staple leg 244p and / or 244d extends beyond the deck 233 when the staple 240 is in the unlaunched position. Primarily with reference to FIGS. 4 and 6, the cartridge body 232 further comprises a protrusion 236 extending above the deck 233, which protrusion at least partially at the tip 246 when the staple 240 is in the unlaunched position. It is configured to surround. The lengths of the staple legs 244p and 244d are chosen so that the tip 246 is located below the upper surface of the protrusion 236 when the staple 240 is in the unlaunched position. In some respects, the protrusion 236 extends the staple cavity 234 above the deck 233. Such a configuration may allow the use of longer or higher staples while at the same time protecting the staples even though they extend above deck 233. The protrusion 236 is also configured to guide the staple leg 244 as the staple 240 is ejected from the staple cavity 234.
In addition to the above, the staple 240 reaches a full firing configuration as the top surface 253 of the longitudinal lamp 255 passes below the bottom surface of the staple 240. Referring now to FIG. 12, the staple 240 has almost reached the top surface 253 of the longitudinal lamp 255 and thus has almost reached the full firing configuration. When the top surface 253 moves distal to the deformed staple 240 and becomes disengaged from the deformed staple 240, elastic reaction forces and / or potential energy stored in the deformed staple 240 , A portion of the deformed staple 240 may be pushed back into the ejected staple cavity 234a.
Referring again to FIGS. 11 and 12, the anvil 120 comprises molded pockets configured to deform the staples 240 and 240'. The molded pockets are, for example, a proximal molded cup 124p configured to receive the proximal staple leg 244p of the staple 240 and a distal molded pocket configured to receive the distal staple leg 244d of the staple 240, respectively. Equipped with cup 124d. The proximal molded cup 124p is configured to deform the proximal staple leg 244p inward toward the distal staple leg 244d. Similarly, the distal molded cup 124d is configured to deform the distal staple leg 244d inward towards the proximal staple leg 244p. Other embodiments are also conceivable in which one or both of the staple legs 244p and 244d are bent outward and / or in any other suitable direction away from each other. Referring again to FIG. 12, the staples 240 and 240'are transformed into a B-shaped configuration by the anvil 120, however, the anvil 120 transforms the staples 240 and 240' into any suitable configuration. It may be configured to cause.
As discussed above, the end effector 100 can be used with the staple cartridge 100 or, as an alternative, with the staple cartridge 200. As a result, the anvil 120 is configured to deform the staple 140 of the staple cartridge 100 and, in addition, the staples 240, 240'of the staple cartridge 200. In other words, for example, the molded pockets defined in the anvil 120 are configured to deform staple 140 made from bent wire and staple 240 or staple 240' punched out from a flat sheet of material, respectively. Has been done. For example, primarily referring to FIG. 6, the proximal molding cup 124p of the molding pocket is configured to deform the proximal staple leg 144 of the staple 140 and the proximal staple leg 244p of the staple 240. The proximal molded cup 124p of the molded pocket is also configured to deform the proximal staple leg 244p'when the staple 240'is aligned with the molded pocket on behalf of the staple 240. Similar to the above, the distal molded cup 124d of the molded pocket is configured to deform the distal staple leg 144 of the staple 140 and the distal staple leg 244d of the staple 240. Similarly, the distal molded cup 124d of the molded pocket is also configured to deform the distal staple leg 244d'when the staple 240'is aligned with the molded pocket on behalf of the staple 240.
In addition to the above, the staple cavity 134 of the staple cartridge 130 and the staple cavity 234a of the staple cartridge 230 have the tip 146 of the staple 140 and the tip 246 of the staple 240 depending on which staple cartridge is attached to the end effector 100. Alignable with the molding pockets of the anvil 120 to strike the same points or targets in the molding cups 124p and 124d. It should be understood that the tips 146 and 246 may not actually hit the same target in the molded cups 124p and 124d, for example due to variations in tissue composition. That is, the molded cavity of the anvil 120 is configured to guide the legs 144 of the staple 140 and the legs 244p, 244d of the staple 240 to the desired alignment state. For this purpose, the proximal molded cup 124p is equipped with a guide wall 126p, the distal molded cup 124d is equipped with a guide wall 126d, and the guide wall has the legs of staples 140, 240, and 240'to the desired configuration. It is configured to guide and mold.
Referring again to FIG. 7, the staple 240 comprises a tissue engaging surface 243 defined on the top surface of the crown portion 242. The surface 243 of the staple 240 is configured to support and / or apply pressure to the tissue trapped within the staple 240 as the staple 240 is formed into a firing configuration. Referring here to FIG. 11, the surface 243 of the staple 240 is located well below the deck 233 of the cartridge body 232 when the staple 240 is in the unlaunched position. Now referring to FIG. 12, when the staple 240 is moved to the launch position, the surface 243 appears at least partially above the deck 233. In other words, the thread 250 is at least partially overdriven over the staple 240. In such cases, the surface 243 of the staple 240 may abut and apply pressure to the tissue when the staple 240 is deformed. In some cases, when the staple 240 is in full launch position, only a portion of surface 243 is overdriven above deck 233. In other cases, when the staple 240 is in full launch position, the entire surface 243 is overdriven above the deck 233. Such a configuration allows a significant amount of clamping pressure to be applied to the tissue, thereby reducing bleeding from the tissue.
In various examples, in addition to the above, the staple 240 driver 246 is still at least partially below the deck 233, even when the surface 243 of the staple 240 is overdriven above the deck 233. In some cases, the staple 240 is configured so that the driver 246 does not spawn above the deck 233, regardless of how much the surface 243 is overdriven above the deck 233. In such cases, the entire driver 246 remains below deck 233 during the staple firing process. In at least one example, the cam surface 245 of the staple 240 does not appear above the deck 233 when the staple 240 is overdriven. In various examples, the top surface 253 of the longitudinal ramp 255 does not extend above the deck 233. This means that the thread 250 does not drive the entire staple 240 above the deck 233 during the staple firing stroke.
In addition to the above, it should be understood that the protrusion 236 extends above the deck 233. As shown in FIG. 12, the thread 250 is configured to overdrive the surface 243 of the staple 240 at least partially above the protrusion 236. In such an example, when the staple 240 is moved to the full launch position, the surface 243 rises at least partially above the protrusion 236. In some cases, when the staple 240 is in the full launch position, only a portion of the surface 243 is overdriven above the protrusion 246. In other cases, when the staple 240 is in full launch position, the entire surface 243 is overdriven above the protrusion 246. Such a configuration allows a significant amount of clamping pressure to be applied to the tissue, thereby reducing bleeding from the tissue.
In addition to the above, the tissue engagement surface 243 may directly engage or contact the tissue. In other cases, for example, a piece of buttress material and / or an auxiliary material such as a tissue thickness compensator may be placed on the deck 233 of the staple cartridge 230, and the tissue engagement surface 243 may be the auxiliary material. It may be directly engaged or contacted. References disclosing auxiliary materials are incorporated by reference elsewhere in the application.
Referring again to FIG. 7, the tissue engaging surface 243 has a flat portion, a first inclined portion on the first side of the flat portion, and a second inclined portion on the second side of the flat portion. It is equipped with. With such a configuration, pressure can be applied from three directions to the tissue trapped in the staple 240. That is, the tissue engaging surface 243 may have any suitable configuration, for example, a completely flat configuration or a rounded configuration.
As discussed above, again with reference to FIG. 6, the staple cartridges 130 and 230 can be selectively and interchangeably used with the end effector 100. Similarly, as discussed above, the staple cartridges 130 and 230 are removable and attachable to the jaw 110. In various alternative embodiments, the staple cartridges 130 and 230 each have a complete jaw that can be attached to and removed from the frame 190 of the end effector 110. In such cases, the clinician, for example, removes the entire staple cartridge jaw from the end effector 110 and another complete staple cartridge jaw, i.e., the type of staple that has not yet been fired and is desired by the clinician. Or it can be replaced with one with a patterned staple.
In addition to the above, it should be understood that FIG. 6 is intended to show that the end effector 100 can be used with the staple cartridge 130 and the staple cartridge 230. Although both the staple cartridge 130 and the staple cartridge 230 are shown in FIG. 6, it should be understood that the staple cartridge 130 and the staple cartridge 230 are not used simultaneously within the same end effector 100. That is, for example, various embodiments are conceivable in which the staple cartridge utilizes wire staples and, in addition, staples formed from one or more sheet materials. In at least one embodiment, the staple cartridge comprises, for example, a staple 140 and a staple 240 detachably housed therein. For example, other embodiments in which the staple cartridge comprises staple 140, staple 240, and staple 240'can be considered.
Referring to FIG. 20, in addition to the above, the staple cartridge 430 comprises a cartridge body 432 including a deck 433 and a longitudinal slot 135 defined therein. The longitudinal slot 135 defines a longitudinal slot axis 139 extending through its center. The staple cartridge 430 has a row of first or inner longitudinal cavities 434a, a second or middle row of longitudinal staple cavities 434b, and a third row of staple cavities 434b on one side of the longitudinal slot 135. It further comprises a row of staple cavities 434c extending in the longitudinal direction of or outside. The staple cartridge 430 also has a row of first or inner longitudinal cavities 434a'and a second or middle row of longitudinal staple cavities 434b' on the other side of the longitudinal slot 135. And a row of staple cavities 434c'extending in the third or outer longitudinal direction. The staple cavities 434a, 434a', 434b, and 434b' are in many respects similar to the left staple cavities 234a (FIGS. 4 and 6). The staple cavities 434c and 434c'are similar to the left staple cavities 134 (FIGS. 2 and 6) in many respects. The staple 240 is detachably stored in the staple cavities 434a, 434a', 434b, and 434b'. The staple 140 is detachably stored in the staple cavities 434c and 434c'.
Referring to FIG. 21, the staple cartridge 430 further comprises a thread 450 configured to eject staples 140 and 240 from the cartridge body 432. The thread 450 directly engages the longitudinal ramp 455a configured to engage directly with the staple 240 housed in the staple cavity 434a and the staple 240 housed within the staple cavity 434a'. Longitudinal lamps 455a'configured to engage directly with staples 240 housed in staple cavities 434b, and staples housed in staple cavities 434b'. It features a longitudinal ramp 455b', which is configured to engage directly with the 240. The thread 450 further comprises a longitudinal lamp 455c configured to eject the staple 140 from the staple cavity 434c and a longitudinal lamp 455c' configured to eject the staple 140 from the staple cavity 434c'. .. More specifically, the staple cartridge 430 is housed in a staple cavity 434c'with a row of staple drivers configured to support and / or engage the staple 140 housed in the staple cavity 434c. It comprises a row of staple drivers configured to support and / or engage with the staple 140, and also in the longitudinal direction of the thread 450 as it is advanced distally. The ramps 455c and 455c'engage with the staple driver to lift the staple 140 upwards within the staple cavities 434c and 434c', deforming the staple 140 against an anvil located opposite the staple cartridge 430. These staple drivers can be similar in many respects to, for example, the staple driver shown in FIG. 3A.
In addition to the above, the staple cavity 434a is located along the longitudinal axis 437a, the staple cavity 434b is located along the longitudinal axis 437b, and the staple cavity 434c is located along the longitudinal axis 437c. Similarly, the staple cavity 434a'is located along the longitudinal axis 437a', the staple cavity 434b'is located along the longitudinal axis 437b', and the staple cavity 434c'is located along the longitudinal axis 437c'. ing. The distance between the longitudinal axis 437a and the longitudinal slot axis 139 is shorter than the distance between the longitudinal axis 437a'and the longitudinal slot axis 139. As a result, the longitudinal axis 437a'is laterally staggered or displaced as compared to the longitudinal axis 437a. Similarly, the distance between the row of longitudinally extending staple cavities 434a and the longitudinal slot 135 is shorter than the distance between the longitudinally extending staple cavities 434a'and the longitudinal slot 135. In addition, the distance between the longitudinal axis 437b and the longitudinal slot axis 139 is shorter than the distance between the longitudinal axis 437b'and the longitudinal slot axis 139. As a result, the longitudinal axis 437b'is laterally staggered or displaced as compared to the longitudinal axis 437b. Similarly, the distance between the row of longitudinal staple cavities 434b and the longitudinal slot 135 is shorter than the distance between the row of longitudinal staple cavities 434b'and the longitudinal slot 135. For comparison, the longitudinal axis 437c and the longitudinal axis 437c'are equidistant from the longitudinal slot axis 139. Correspondingly, the rows of longitudinally extending staple cavities 343c and the rows of longitudinally extending staple cavities 343c'are equidistant from the longitudinal slot 135.
The rows of longitudinally defined staple cavities defined within the staple cartridge 430 are not evenly spaced. In many respects, the distances between longitudinal columns are different. As can be seen in FIG. 20, the spacing between the rows of longitudinal staple cavities 434a, 434b, and 434c on one side of the longitudinal slot 135 is the longitudinal staple cavities on the other side of the longitudinal slot 135. It is different from the column spacing of 434a', 434b', and 434c'.
In addition to the above, the longitudinal axes 437a, 437a', 437b, 437b', 437c, and 437c' include drive axes. These drive axes are optionally aligned with the drive portion of the staple 240 and the cam surface of the staple driver supporting the staple 140. The longitudinal ramp of the thread 450 is aligned with these drive axes. For example, referring to FIGS. 20 and 21, the longitudinal ramp 455a of the thread 450 is aligned with the longitudinal axis 437a. Similarly, the longitudinal ramp 455b is aligned with the longitudinal axis 437b and the longitudinal ramp 455c is aligned with the longitudinal axis 437c. Also, the longitudinal ramp 455a'is aligned with the longitudinal axis 437a', the longitudinal ramp 455b'is aligned with the longitudinal axis 437b', and the longitudinal ramp 455c'is aligned with the longitudinal axis 437c'. For this purpose, the longitudinal ramp 455a and the longitudinal axis 437a are separated from the longitudinal slot axis 139 by a distance of 457a, and the longitudinal ramp 455b and the longitudinal axis 437b are separated from the longitudinal slot axis 139 by a distance of 457b. The longitudinal ramp 455c and the longitudinal axis 437c are separated from the longitudinal slot axis 139 by a distance of 457c. Similarly, the longitudinal ramp 455a'and the longitudinal axis 437a' are separated from the longitudinal slot axis 139 by a distance of 457a', and the longitudinal ramp 455b'and the longitudinal axis 437b' are separated from the longitudinal slot axis 139 by a distance of 457b'. The longitudinal ramp 455c'and the longitudinal axis 437c'are separated from the longitudinal slot axis 139 by a distance of 457c'.
As can be seen in FIG. 21, the distances 457a, 457a', 457b, and 457b'are not equal. These are all different. As a result, the rails of the threads 450 are asymmetrically separated.
Referring to FIG. 21, the thread 450 comprises a central portion 451 configured to move within the longitudinal slot 135 of the cartridge body 432. Since the central portion 451 is sized and configured to be tightly received within slot 135, lateral movement between the thread 450 and the cartridge body 432, if any, is largely unacceptable. The longitudinal ramp of the thread 450 remains properly aligned with the staple 240 and the staple driver configured to drive the staple 140.
Referring again to FIG. 20, the staples in the outer row deployed by the staple cartridge 430 are wire staples, and the staples in the inner and middle rows deployed by the staple cartridge 430 are formed from flat stock and / or striking. It was pulled out. However, other configurations are possible. In at least one example, for example, the staples in the middle and outer rows deployed by the staple cartridge are wire staples and the staples in the inner row deployed by the staple cartridge are punched staples. In another example, for example, the inner and middle row staples deployed by the staple cartridge are wire staples and the outer row staples deployed by the staple cartridge are punched staples. If the staple cartridge deploys two or more rows of wire staples on one side of the longitudinal slot, a two or more rows of staple drivers may be utilized to deploy the staples from the staple cartridge. In various examples, the staple cartridge may utilize, for example, a double screwdriver, which simultaneously deploys wire staples from two longitudinal rows when the longitudinal rows containing the wire staples are adjacent to each other. It is configured to do so. Other driver configurations configured to deploy more than two staples, for example three staples and / or four staples, may be utilized.
As a result of the above, the staple cartridge 430 produces an asymmetric pattern of staples in the tissue. In particular, the staple cartridge 430 produces a first pattern of staples on the tissue on the first side of the cutting line and a second or different pattern of staples on the tissue on the second side of the cutting line.
Referring here to FIGS. 15-19, the staple cartridge 330 comprises a deck 333 and a cartridge body 332 including a longitudinal slot 135 defined therein.

As a result, the longitudinal axis 337a'is laterally staggered or displaced as compared to the longitudinal axis 337a. Similarly, the distance between the row of longitudinal staple cavities 334a and the longitudinal slot 135 is shorter than the distance between the row of longitudinal staple cavities 334a'and the longitudinal slot 135.
In addition, the distance between the longitudinal axis 337b and the longitudinal slot axis 139 is shorter than the distance between the longitudinal axis 337b'and the longitudinal slot axis 139.
