[Conventional technology]

In recent years, an endoscopy system in which a light source, a video processor, a bed, an observation monitor, a high-frequency ablation device, and the like necessary for endoscopy are built into an integrated system and centrally controlled by a touch panel has been used in hospitals. In such a conventional endoscopic system, a patient is laid on a bed for examination and treatment. As an example of the conventional endoscope system, there is a system shown in Japanese Patent Application Laid-Open No. 5-39013.

【0003】

However, in a conventional endoscope system, the positional relationship between the bed and the scope connector connecting the endoscope is fixed on the assumption that the patient is moved to the bed of the system and the examination is performed on the bed. .. For this reason, for example, even when performing an endoscopy on a patient who cannot walk on his own, the patient must be moved to the bed of the endoscopy system, which requires an extremely large amount of labor. Furthermore, for example, for patients whose general condition is poor and cannot be transferred from a stretcher or the like, endoscopy cannot be performed with this type of endoscopy system in the first place.

【0004】

[Problems to be Solved by the Invention]

As described above, conventionally, in order to perform an examination and treatment, it is necessary to transfer the patient to the bed, which requires an extremely large amount of labor, and in some cases, the examination may not be possible. was there.

【0005】

The present invention has been made in view of such a problem, and an endoscopy system capable of saving the trouble of transferring a patient to a bed and making it possible to perform an endoscopy reliably with a small amount of labor. The purpose is to provide.

【0006】

Another object of the present invention is to provide an endoscopic system capable of performing endoscopy on a patient at a position other than the bed without the trouble of transferring the patient to the bed. To do.

【0007】

[Means for solving problems]

The endoscope system according to the present invention is characterized in that, in an endoscope system consisting of a bed and at least one or more units including a light source device, the positional relationship between the bed and the unit is variable. To do.

【0008】

In the present invention, the unit is made movable relative to the bed of the endoscopic system. If the patient is located outside the bed, the unit is moved according to the patient's position. This makes it possible to perform endoscopy and treatment even for patients located outside the bed.

【0009】

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 5 relate to the first embodiment of the present invention, FIG. 1 is a perspective view showing an endoscopic system, FIG. 2 is a top view showing the lower part of the main unit 2 together with Prince 9, and FIG. 3 is a main unit. The lower part of 2 is a side view seen from the direction A of FIG. 2, and FIGS. 4 and 5 are top views for explaining the state of endoscopy.

【0010】

In this embodiment, the prince 9 and the main unit 2 are provided with a mechanism for moving the main unit 2, so that endoscopy of the patient can be performed in a wide range.

【0011】

In FIG. 1, the endoscope system 1 is composed of a main unit 2 and a bed 7 arranged on an L-shaped prince 9. Prince 9 has a substantially planar shape on the upper surface, and is L-shaped in which a long flat surface portion and a short flat surface portion are formed at right angles. The bed 7 is arranged on the long flat surface portion of the prince 9, and the main unit 2 is arranged on the short flat surface portion side.

【0012】

The main unit 2 contains a light source unit for endoscopy (not shown), a video processor, a treatment device such as an electric knife, a photography device, and the like. The touch panel 4 is rotatably attached to the upper part of the main unit 2 with respect to the main unit 2, and by operating the touch panel 4, the devices built in the main unit 2 can be centrally controlled. It has become.

【0013】

Light from the light source device is led out to the connector 5. By connecting a light guide cable (not shown) connected to an endoscope (not shown) to this connector 5, the illumination light from the light source device is transmitted from the tip of the insertion portion via the light guide in the endoscope insertion portion. It is possible to irradiate the observation site.

【0014】

Further, the connector 6 is connected to a signal cable (not shown) connected to the endoscope. As a result, the CCD provided at the tip of the insertion portion of the endoscope and the video processor in the main unit 2 are electrically connected.

【0015】

Bed 7 is fixed on a table provided approximately in the center of the long flat surface of Prince 9. At the end of the long flat surface below the bed 7, subunit 8 is provided on the long flat surface. The subunit 8 houses the power supply and the like of the main unit 2. The main unit 2 and the subunit 8 are connected via a plurality of cables, and these cables are housed in the prince 9 as described later.

【0016】

The main unit 2 is arranged so that the operation surfaces of the connectors 5 and 6 and the touch panel 4 face the space side facing the longitudinal side surface of the bed 7, and the operator lays this space, that is, the patient on the bed 7. In such a case, the endoscopy and treatment are performed from a position where the touch panel 4 and the instruments attached to the main unit 2 can be operated while being positioned on the side of the patient.

【0017】

A monitor 3 for observation is placed on the monitor stand 10 behind the bed 7 when viewed from the operator's side. The monitor stand 10 has a pedestal attached to an arm attached to a support column, and the monitor 3 is mounted on the pedestal. In FIGS. 2 and 3, the main unit 2 has a pedestal 11 attached to the bottom surface. FIG. 2 shows only the part below the platform 11. Casters 12 are attached to the four corners of the bottom surface of the base 11, and the main unit 2 can be moved by the casters 12. The caster 12 is rotatably attached to the base 11 around a shaft (not shown). A pair of roller units 13 are fixed to the front end of the base 11. Each roller unit 13 has two rotatable rollers 14 arranged in the front-rear direction of the base 11.

【0018】

The Prince 9 has a frame 15 having a predetermined length formed on a short flat surface portion. The frame 15 has a cavity inside, and both side surfaces are formed substantially parallel to each other, and is configured to have substantially the same width as the distance between the rollers 14 of the pair of roller units 13. By installing the base 11 so that both side surfaces of the frame 15 are sandwiched between the rollers 14, the main unit 2 is guided by the frame 15 in the direction along the short flat surface portion of the prince 9, that is, perpendicular to the long flat surface portion. It is movable in the direction by the casters 12.

【0019】

A stopper 16 is provided below the main unit 2 at a position facing the rear end surface of the frame 15, and the main unit 2 is moved along the frame 15 in a direction approaching the bed 7 (hereinafter referred to as the front side). In this case, the stopper 16 comes into contact with the rear end surface of the frame 15 to stop the movement of the main unit 2.

【0020】

Further, FIG. 3 shows Prince 9 and the main unit 2 as viewed from the direction of the arrow A in FIG. In FIG. 3, a part of Prince 9 is cut and shown below the main unit 2. A cable 18 connecting the main unit 2 and the subunit 8 is arranged in the cavity in the frame 15. The cavity in the frame 15 is composed of two stages, an upper stage and a lower stage. The cable 18 connected to the main unit 2 is extended to the rear side in the upper stage, folded back at a predetermined position, and extended to the front side in the lower stage, and is connected to the subunit 8. That is, the cable 18 is bent up and down and housed in the upper and lower cavities of the frame 15, and when the main unit 2 moves, the cable 18 also moves between the upper and lower cavities, and the main unit 2 and the subunit 2 also move. The connection with unit 8 will not be broken.

【0021】

Next, the operation of the embodiment configured in this way will be described with reference to FIGS. 4 and 5.

【0022】

Now, it is assumed that the patient is laid on the bed 7 and the endoscopy is performed. In this case, the main unit 2 is positioned closer to the bed 7 side. The surgeon works at a position facing both the bed 7 and the main unit 2. FIG. 4 shows this state, and the operator can operate the touch panel 4 of the main unit 2 and the like by simply moving the position of the body slightly from the state of standing beside the patient. With the body facing the patient, the display screen of the monitor 3 provided substantially in front can be seen.

【0023】

Next, endoscopy using the stretcher 21 shall be performed. In this case, push the main unit 2 and move it in the direction of arrow B in FIG. The rollers 14 abutting on both side surfaces of the frame 15 rotate, and the main unit 2 is moved along the frame 15 by the casters 12.

【0024】

In this case, the folded portion of the cable 18 which is folded and stored in the cavity in the prince 9 in the upper and lower stages moves rearward as the main unit 2 moves rearward. As a result, the length of the part housed on the lower side of the cable 18 becomes longer, and even if the distance between the main unit 2 and the subunit 8 becomes large, the connection between the main unit 2 and the subunit 8 can be established. Be maintained.

【0025】

When the main unit 2 is sufficiently moved backward, the stretcher 21 on which the patient is lying is positioned to the side of the bed 7, as shown in FIG. That is, in this case, the positional relationship between the stretcher 21 and the main unit 2 is the same as the relationship between the bed 7 and the main unit 2 in FIG.

【0026】

The surgeon works at a position facing both the stretcher 21 and the main unit 2. Therefore, as in the case of FIG. 4, the operator operates the touch panel 4 and the like of the main unit 2 by simply moving the position of the body slightly from the state of standing beside the patient sleeping on the stretcher 21. In addition, the display screen of the monitor provided substantially in front of the patient can be viewed with the body facing the patient. As a result, even for the patient transported by the stretcher 21, it is possible to perform endoscopy or the like as it is without moving the patient to the bed.

【0027】

As described above, the touch panel 4 is rotatable. For example, by rotating the touch panel 4 as appropriate, the touch panel 4 can be operated from the direction of the arrow 24 in FIG. 5, and as shown in FIG. 5, the touch panel 4 and the monitor 3 are connected by a line. It is also possible to rotate the touch panel 4 to a rotation position where the nurse 25 can be operated. In this case, the nurse 25 can check the monitor 3 and operate the touch panel 4 with almost no movement of the line of sight when inputting patient data or the like.

【0028】

As described above, in the present embodiment, the prince 9 and the main unit 2 are provided with a mechanism for moving the main unit 2 in the direction perpendicular to the bed 7, and the main unit 2 and the subunit 8 are connected to each other. By providing a mechanism for folding and storing the cable 18 in the prince 9, it is possible to move the main unit 2 and arrange the stretcher in the empty space. This allows endoscopy to be performed on the patient on the stretcher, eliminating the need to transfer the patient to bed, reducing the required personnel and labor, and ensuring endoscopy and treatment. Etc. are made possible.

【0029】

FIG. 6 is a perspective view showing an endoscope system according to a second embodiment of the present invention.

【0030】

This embodiment differs from the first embodiment only in the mechanism that enables the movement of the main unit. In FIG. 6, the endoscope system 30 uses the prince 40 and the main unit 31 in place of the prince 9 and the main unit 2, respectively, and uses the cable 34 in place of the cable 18 in FIG. Different from system 1.

【0031】

The main unit 31 has a built-in functional unit similar to that of the main unit 2 of the first embodiment. A touch panel 39 is attached to the main unit 31, and the devices built in the main unit 2 can be centrally controlled by operating the touch panel 39.

【0032】

In the present embodiment, casters 32 are attached to the bottom surface of the main unit 31, and the main unit 31 is movable in all directions by the casters 32.

【0033】

Further, the front panel 41 of the main unit 31 is formed in a recessed shape. As a result, even if an operator or the like approaches, he / she does not hit his / her foot. Further, a camera 42 of a photo-imaging device is provided in the vicinity of the touch panel 39 on the upper surface of the main unit 31. The touch panel 39 is used as the eaves for the camera 42 to be installed. A table 43 is configured on the upper surface of the main unit 31. The table 43 has a larger area than the cross section at any position of the main unit 31.

【0034】

The prince 40 is formed in a rectangular shape having a substantially flat upper surface, a bed 36 is attached to the central portion, and a subunit 33 is arranged at the end portion. A monitor stand 37 is provided behind the bed 36. The monitor stand 37 has an arm, and the monitor 38 is placed on a pedestal provided on the arm.

【0035】

In the present embodiment, the main unit 31 and the subunit 33 are connected by a cable 34. The cable 34 is built inside the tube 35 and is protected from the outside.

【0036】

The main unit 31 and the subunit 33 are also connected by a wire (not shown), and the wire is also housed in the tube 35.

【0037】

Next, the operation of the embodiment configured in this way will be described.

【0038】

In the present embodiment, the position of the main unit 31 is changed according to the position of the patient. For example, when performing endoscopy with the patient lying on the bed 36, the main unit 31 is positioned close to the bed 36. Further, for example, when performing endoscopy with the patient placed on a stretcher (not shown), the main unit 31 is positioned in the vicinity of the stretcher.

【0039】

When a force is applied to the main unit 31 in a predetermined direction, the main unit 31 is moved by the casters 32. The subunit 33 and the main unit 31 are connected by a cable 34 housed in a flexible tube 35, and the casters 32 are mounted so as to be rotatable in the horizontal direction, so that the main unit 31 is omnidirectional. It is movable, and the main unit 31 can be moved to any position.

【0040】

The main unit 31 and the subunit 33 are connected by a wire (not shown), and the main unit 31 is not separated from the subunit 33 by a certain distance or more. In addition, the tube 35 has a function of protecting the built-in cable 34 and the wire from dust, chemicals, etc. in the endoscopy room.

【0041】

The camera 42 is arranged near the touch panel 39 on the main unit 31, and the camera 42 is in an easy-to-operate position for both the doctor and the nurse who are the surgeons. In addition, the touch panel 39 protects the camera 42 from above so that liquid or the like does not accidentally spill on the camera 42.

【0042】

Further, since the outer edge of the table 43 is outside the cross section at any position of the main unit 31, the liquid on the table 43 is the main unit even when the cup containing the liquid is laid down on the table 43, for example. It will fall to the outside of the side of 31 and will not hang directly on the main unit 31.

【0043】

As described above, the same effect as that of the first embodiment can be obtained in the present embodiment as well. Further, since the mechanism for moving the main unit 31 is configured relatively easily, there is an advantage that the cost can be reduced as compared with the first embodiment.

【0044】

FIG. 7 is a perspective view showing an endoscope system according to a third embodiment of the present invention.

【0045】

Also in the present embodiment, the mechanism that enables the movement of the main unit is different from that of the first embodiment. In FIG. 7, the bed 300 and subunit 201 are mounted on the bed base 301. The main unit 200 has the same built-in devices and their functions as the main unit 2 in FIG. The main unit 200 and the subunit 201 are connected by a harness (not shown) built in the link 202.

【0046】

The link 202 has a joint portion 203 and is flexible and stretchable at the joint portion 203. One end of the link 202 is rotatably attached to a shaft (not shown) fixed to the bottom surface of the subunit 200, and the other end is rotatably attached to a shaft (not shown) fixed to the bottom surface side of the subunit 201. The link 202 has a built-in harness (not shown) that connects the main unit 200 and the subunit 201.

【0047】

The main unit 200 has a built-in light source device (not shown), and the exterior panel 213 of the main unit 200 is provided with a heat exhaust slit 205 for exhausting heat from the light source device lamp. The exterior panel 213 has a curved surface and an inclined surface, and by appropriately setting the position of the light source device lamp and the shape and position of the heat exhaust slit 205, heat is exhausted in the direction of arrow 206 in FIG. 7 and indicates the direction of the bed 300. Heat is not exhausted in the direction of arrow 207. Further, the exterior panel 213 is provided with an electric knife output connector group 212 along the curved surface of the exterior panel 213.

【0048】

Behind the bed base 301, a stand base 303 fixed to the bed base 301 is provided. A monitor stand 302 is fixed to the stand base 303. The monitor stand 302 has an arm, and the monitor is mounted on a pedestal rotatably attached to the arm. The bed base 301 and the stand base 303 may be configured as an integral member.

【0049】

The monitor stand 302 is provided with a storage box 304. The storage box 304 has an opening 305 towards the rear side of the bed 300. The monitor stand 302 is also provided with a table 306.

【0050】

Next, the operation of the embodiment configured in this way will be described.

【0051】

Also in this embodiment, the position of the main unit 200 is changed according to the position of the patient. For example, when performing endoscopy with the patient lying on the bed 36, the main unit 200 is positioned close to the bed 300, and for example, the patient is placed on a stretcher (not shown) inside. When performing endoscopy, the main unit 200 is located near this stretcher.

【0052】

When a force is applied to the main unit 200 in a predetermined direction, the link 202 bends and stretches by the shaft and the joint 203 fixed to the main unit 200 and the subunit 201 side, and the position of the main unit 200 is linked to the link 202. It can be moved to any position within the length of.

【0053】

The harness in the link 202 connects the main unit 200 and the subunit 201, and even if the main unit 200 moves, the connection between the main unit 200 and the subunit 201 is not broken.

【0054】

Further, in the present embodiment, since the output connector group 212 of the electric knife is provided on the curved surface of the exterior panel 213 on the bed 300 side, for example, a treatment tool such as a high-frequency snare can be directed toward the bed. .. Since the electric knife connector group 212 is oriented in a direction that facilitates inspection and replacement, inspection efficiency can be improved.

【0055】

The monitor stand 302 receives a large moment at the root fixing portion, but since the stand base 303 is fixed to the bed base 301, the monitor stand 302 does not become unstable. Therefore, it is not necessary to fix the monitor stand 302 to the floor surface with anchor bolts or the like, and the installation work is easy.

【0056】

Further, since the table 306 is attached to the monitor stand 302, a patient condition measuring device such as a sphygmomanometer and a pulse oximeter can be used on the table 306. Unused cuffs and the like can be stored in the storage box 304. Since the opening 305 of the storage box 304 faces the rear side of the bed 300, the objects stored in the storage box 304 cannot be seen by the surgeon performing endoscopy or the like.

【0057】

In general, the nurse frequently works near the side surface of the main unit 200 in the front-rear direction of the bed 300. In the present embodiment, the heat exhaust slit 205 exhausts heat in the direction of arrow 206 and does not exhaust heat in the direction in which the nurse is frequently located, so that a comfortable inspection environment can be provided.

【0058】

As described above, the same effect as that of the embodiment of FIG. 1 can be obtained in this embodiment as well. Further, in the present embodiment, the installation work of the monitor stand can be simplified and the introduction cost can be reduced. Further, it has an advantage that workability is improved by considering the mounting position of the heat exhaust slit and the connector group provided on the exterior panel of the main unit.

【0059】

8 and 9 relate to the fourth embodiment of the present invention, FIG. 8 is a side view of the lower part of the main unit as viewed from the bed side, and FIG. 9 is a side view of the vicinity of the subframe 51 in FIG. It is a top view which shows the part of. In FIG. 8, the casters are not shown in order to simplify the drawing.

【0060】

In this embodiment, only the configuration of the lower part of the main unit is different from that of the first embodiment, and the main unit is provided with a stopper that can be freely operated and released.

【0061】

The main unit 50 has a base 11 attached to the bottom surface, and a subframe 51 is fixed to the base 11 along the side surface. A shaft 53 is attached to the subframe 51 in the vertical direction, and the stopper arm 52 is rotatably supported in the horizontal direction by the shaft 53 and the spacer 54 at substantially the center of the arm.

【0062】

The shaft 53 is arranged outside the side surface of the base 11. The stopper arm 52 is bent at a portion pivotally supported by the shaft 53, one end of which is located outside the side surface of the base 11, and the other end of which is located inside the side surface of the base 11. A shaft base 59 is attached to the other end of the stopper arm 52 so as to be inclined with respect to the longitudinal direction of the stopper arm 52. A rotatable core shaft 55 is attached to the shaft base 59.

【0063】

A cylindrical neoprene (registered trademark) rubber 56 having a predetermined thickness in the radial direction is attached around the core shaft 55. The material of this portion may generally be a rubber-based elastic member, or may be a material that causes friction, such as a sponge-based material.

【0064】

When one end side of the stopper arm 52 is parallel to the side surface of the base 11 (two-dot chain line in FIG. 9), the neoprene rubber 56 is located near the side surface of the base 11, and one end side of the stopper arm 52 is from the side surface of the base 11. When they are separated (solid line in FIG. 9), the core shaft 55 is substantially parallel to the side surface of the base 11, and the neoprene rubber 56 moves inward from the side surface of the base 11. There is.

【0065】

A slope member 57 is fixed to the bottom surface of the base 11 corresponding to the stop position of the neoprene rubber 56 in this case. The slope member 57 has an inclined portion inclined so as to approach the floor side from the side surface of the table 11 toward the inside. In the inclined portion, the distance between the floor and the slope member 57 is set to be smaller than the diameter of the neoprene rubber 56 inside the table 11.

【0066】

Next, the operation of the embodiment configured in this way will be described.

【0067】

Similar to the first embodiment, the main unit 50 can be guided by the frame and can be moved in the vertical direction of the paper surface of FIG. 8 (direction A of FIG. 9). Now, after moving the main unit 50 to a desired position, it is assumed that the main unit 50 is stopped by the function of the stopper.

【0068】

The two-dot chain line in FIG. 9 shows the state in which the stopper is released. That is, in the stopper released state, one end side of the stopper arm 52 is parallel to the side surface of the base 11, that is, parallel to the moving direction of the main unit 50. Further, the other end side of the stopper arm 52 is located near the side surface of the table 11 with the core shaft 55 slightly inclined with respect to the side surface of the table 11.

【0069】

Here, for example, a human foot moves the stopper arm 52 in the direction of arrow 58 in FIG. Then, the core shaft 55 attached to the other end of the stopper arm 52 moves to the inside of the base 11 while changing its direction. As a result, the neoprene rubber 56 attached to the core shaft 55 dives under the inclined portion of the slope member 57, the neoprene rubber 56 is pressed toward the floor surface by the slope member 57, and the clearance with the floor surface gradually decreases. ..

【0070】

When the stopper arm 52 is displaced to the position of the solid line in FIG. 9 (state in FIG. 8), the core shaft 55 including the neoprene rubber 56 is completely press-fitted between the slope member 57 and the floor surface, and the floor surface and the neoprene rubber are completely press-fitted. 56, The frictional force between the neoprene rubber 56 and the slope member 57 hinders the free movement of the main unit 50.

【0071】

As described above, in the present embodiment, the same effect as that of the embodiment of FIG. 1 can be obtained, and since the stopper mechanism is provided, it is possible to prevent the main unit from moving due to an accidental collision or the like. It can be done, and the equipment etc. placed on the main unit will not fall due to the vibration and break.

【0072】

10 to 14 relate to the fifth embodiment of the present invention, FIG. 10 is a perspective view showing an endoscope system, and FIG. 11 is a top view showing a stopper mechanism at the lower part of the main unit 71 in FIG. 12 is a side view of the lower part of the main unit 71 as seen from the direction A in FIG. 11, and FIG. 13 is a cross section showing a part of the side surface portion (near the treatment tool box 86) by cutting the main unit 71 in FIG. 10 in the vertical direction. FIG. 14 is an explanatory view showing details of the storage case 94 in FIG.

【0073】

This embodiment adopts a stopper method different from that of the fourth embodiment. In FIG. 10, the endoscope system 70 is composed of a bed 72, a monitor stand 73, an observation monitor 74, a prince 75, a subunit 76, etc., which are substantially the same as the components of the endoscope system 1 of FIG. There is.

【0074】

Further, regarding the mechanism for moving the main unit 71, that is, the point where the frame 77 is provided on the prince 75, the point where the roller unit 78 is attached to the front end of the base 11 on which the main unit 71 is attached, and the like, the endoscope system shown in FIG. Same as 1.

【0075】

In the present embodiment, only the mechanism of the stopper that releases or activates the movement of the main unit 71 is different from the endoscope system 1 of FIG. In FIGS. 11 and 12, the frame 77 of the Prince 75 has a rack 80 formed on one side thereof. A locking member 101 having a locking portion 81 at a position facing the rack 80 is pivotally supported by a shaft 82 fixed to the bottom surface of the base 11 and is rotatably attached to the base 11 in the horizontal direction. .. A spacer 85 is provided between the shaft 82 and the locking member 101.

【0076】

A torsion coil spring 83 is attached to the shaft 82, and one end of the torsion coil spring 83 abuts on a stopper member 107 fixed to the bottom surface of the base 11, and the other end abuts on a locking member 101 to lock the shaft 82. The member 101 is urged in the direction of arrow 84 in FIG. The locking portion 81 is formed so that the tip of the locking portion 81 meshes with the rack 80. When the locking portion 81 meshes with the rack 80 due to the urging force of the torsion coil spring 83, the locking member 101 blocks the movement of the base 11 of the shaft 82 in the front-rear direction, and the movement of the main unit 71 is blocked. It has become.

【0077】

A treatment tool box 86 is configured on the side surface of the main unit 71. As shown by the broken line in FIG. 10 and the alternate long and short dash line in FIG. 13, the treatment tool box 86 can be opened and closed between the closed position and the open position 87. In FIG. 13, a shaft 89 is provided on the exterior 88 of the main unit 71, and a support member 90 fixed to the lower end of the treatment tool box 86 is pivotally supported by the shaft 89. The treatment tool box 86 opens and closes around the shaft 89.
