The second holding portion 3 is an inclined step portion on which a curved portion bent downward in the operation portion 33 of the scissors 30 can be placed on one surface of the substantially square plate body, that is, the surface in the opening direction of the holding portion 6. 7 The 2nd holding | maintenance part 3 mounts the scissors 30 in this inclination step part 7, and fixes one side of a pair of operation part 33 with a screw | thread etc. (not shown). As will be described later, a guide groove 5 is provided on the surface of the second holding portion 3 opposite to the surface on which the inclined step portion 7 is provided. The size and shape of the second holding portion 3, particularly the inclined step portion 7, are appropriately set according to the size and shape of the surgical instrument. The length of the second holding part 3 in this embodiment in the axial direction (X direction) is preferably 2 to 6 cm, and may be shorter or longer than the length of the first holding part 2 in the axial direction. However, it is preferable from the viewpoint of operability when the electric knife 20 and the scissors 30 are moved in parallel with each other that the length is the same as or shorter than the length of the first holding portion 2 in the axial direction.

  For example, when the electric scalpel 20 is used, the surgical instrument connector 1 displaces the position of the action portion 22 of the electric scalpel 20 relative to the scissors 30 so that the use of the electric scalpel 20 is not hindered. It has a displacement mechanism that can. The displacement mechanism in the surgical instrument connector 1 of this embodiment is such that the electric knife 20 and the scissors 30 are moved in parallel with each other along the axial direction, that is, along the direction connecting the action portions 22 and 32 and the operation portions 23 and 33. This is a parallel movement mechanism.

  The parallel movement mechanism in the surgical instrument connector 1 has a ridge 4 provided in the first holding part 2 and a guide groove 5 provided in the second holding part 3. The guide groove 5 is slidably fitted. Therefore, the guide groove 5 can be slid with respect to the ridge 4. The parallel movement mechanism has a lock mechanism that fixes the first holding unit 2 and the second holding unit 3 at a specific position. With this locking mechanism, when the second holding unit 3 is arranged at the forefront in the X direction with respect to the first holding unit 2 and at the rearmost end in the X direction, the first holding unit 2 and the first holding unit 3 The two holding portions 3 do not move in parallel with each other, and the second holding portion 3 and the first holding portion 2 are fixed during use of the multi-function surgical instrument 10, so that they can be used stably. Can do.

  The ridges 4 in the first holding part 2 are provided in the form of rails on the side surfaces of the substantially square plate-like base body 11 provided in the upper part 92 of the substantially U-shaped holding part 6. That is, the ridge portion 4 is provided along the X direction from one end portion to the other end portion of the surface of the base body 11 where the hold portion 6 is open. The base 11 is provided so as to be orthogonal to the upper portion 92, and is provided on substantially the same plane as the side portion 91. The shape of the ridge portion is not particularly limited as long as it is slidably fitted in the guide groove, but the ridge portion 4 of this embodiment protrudes from the surface of the base 11 on the opening side of the hold portion 6. As shown in FIG. 4, when viewed from the X direction, it is a substantially square shape. More specifically, the ridges 4 have small concave ridges 42 that are prismatic depressions on each of two surfaces facing the Y direction in the prismatic body, and are opposite to the base body 11 in the prismatic body. It has the prism-shaped small ridge part 43 which protrudes from the surface. A hemispherical recess 44 is provided at each end of the small ridge 43 in the X direction, and the recess 44 and a projection 54 in a guide groove 5 described later are fitted together to form a lock mechanism. The shape of the ridges 4 corresponds to the shape of the guide grooves 5, that is, has a complementary relationship and is fitted to each other.

  The guide groove 5 in the second holding part 3 is provided on the surface opposite to the inclined step part 7. The shape of the guide groove is not particularly limited as long as the guide groove is slidably fitted to the ridge. The guide groove 5 of this embodiment has a shape corresponding to the shape of the ridge 4 and is a substantially prismatic recess. More specifically, as shown in FIG. 4, each of the two faces facing in the Y direction in the substantially prismatic recess has a prismatic second small protrusion 52 projecting from these faces, It has the 2nd small groove part 53 which is a prism-shaped hollow in the bottom face in a column-shaped recessed part. A hemispherical protrusion 54 is provided on the tip end side in the X direction on the bottom surface of the second small groove portion 53. In addition, the second holding unit 3 has a displacement operation unit 12 on the surface where the inclined stepped portion 7 is provided. With this displacement operation unit 12, the practitioner can easily displace the second holding unit 3 with respect to the first holding unit 2 by operating the displacement operation unit 12 with a finger.

  The surgical instrument connector 1 of this embodiment has a parallel movement mechanism, and the convex strips 4 and the guide grooves 5 that form the parallel movement mechanism have, for example, the structure described above. 2 and the second holding part 3 are fixed in the Z direction and the Y direction and can be slid relative to each other in the X direction. Moreover, since the surgical instrument connector 1 has the recess 44 and the projection 54 and has a lock mechanism that functions when these are fitted together, the entire bottom surface of the second holding portion 3 is the first surface. When arranged so as to overlap the upper part 92 of the holding unit 2, that is, when the second holding unit 3 is arranged at the most advanced position movable in the X direction with respect to the first holding unit 2, it is for multi-function surgery. During use of the instrument 10, the second holding part 3 and the first holding part 2 are fixed to such an extent that they are not easily displaced from each other. Further, the second holding unit 3 is slid with respect to the first holding unit 2 from this position, and a part of the bottom surface of the second holding unit 3 and a part of the upper part 92 of the first holding unit 3 are When the multifunctional surgical instrument 10 is in use, the second retaining part 3 is disposed at the position of the rearmost end that can move in the X direction with respect to the first retaining part 2. The second holding unit 3 and the first holding unit 2 are fixed to such an extent that they are not easily displaced from each other. Note that the lock mechanism is not limited to an embodiment formed by the recess 44 and the protrusion 54, and may be an embodiment based on a difference in frictional force, for example. That is, the frictional force on the surface where the ridge portion 4 and the guide groove 5 are in contact is not uniform, and the tip end portion in the X direction of the second holding portion 3 is on the tip end side in the X direction with respect to the first holding portion 2. In addition, a mode in which the frictional force is larger when the rear end side is located at each position than when the rear end side is located at other positions, and the position is not easily displaced can be exemplified.

  Next, an example of a method for using the surgical instrument connector 1 of this embodiment and the multi-function surgical instrument 10 in which the electric knife 20 and the scissors 30 are connected via the surgical instrument connector 1 will be described.

  As shown in FIG. 1, first, the electrosurgical knife 20 and the scissors 30 are connected by the surgical instrument connector 1 to obtain a multifunctional surgical instrument 10 that is used by the practitioner. The electric knife 20 is fitted and fixed so that the operation unit 23 is disposed in the holding unit 6 of the first holding unit 2. At this time, the switches 25 and 25 are disposed in the two holes 8 and 8 of the first holding unit 2. The scissors 30 are fixed with screws or the like so that one of the operation portions 33 is disposed on the inclined step portion 7 of the second holding portion 3. In this way, the electric knife 20 and the scissors 30 are fixed to the surgical instrument connector 1.

  The multi-function surgical instrument 10 shown in FIG. 1 is in a state in which the action part 32 of the scissors 30 is distal to the action part 22 of the electric knife 20 from the surgical instrument connector 1. At this time, the entire bottom surface of the second holding part 3 and the upper part 92 of the first holding part 2 overlap. In addition, the protrusion 54 in the second holding unit 3 and the recess 44 in the first holding unit 2 are fitted together to function the lock mechanism, so that the first holding unit 2 and the second holding unit 3 can be easily formed. It is fixed without sliding. The practitioner can hold and use the multifunction surgical instrument 10 with one hand. A pair of operation parts 33 and 33 in the scissors 30 are formed so as to be bent outward and have a spring shape. Therefore, the practitioner closes the pair of cutting blades 35 and 35 in the action portion 32 by applying a force from the outside to the inside of the operation portions 33 and 33 so that the operation portions 33 and 33 are brought close to each other. Can be cut off. At this time, since the action part 32 of the scissors 30 is disposed on the tip end side in the X direction from the action part 22 of the electric scalpel 20, the scissors 30 can be used without being disturbed by the electric scalpel 20.

  Next, when using the electric knife 20, the practitioner operates the displacement operation unit 12 with a finger and slides the second holding unit 3 toward the rear end side in the X direction with respect to the first holding unit 2. Let When the practitioner pushes the displacement operation unit 12 to the rear end side in the X direction with a predetermined force, the lock mechanism is released. Thereby, the action part 32 of the scissors 30 can be displaced so as to be arranged closer to the rear end side in the X direction than the action part 22 of the electric knife 20. When the electric knife 20 is displaced to a position where it is not hindered, a part of the bottom surface of the second holding part 3 and a part of the upper part 92 of the first holding part 2 are overlapped. In addition, the protrusion 54 in the second holding unit 3 and the recess 44 in the first holding unit 2 are fitted together to function the lock mechanism, so that the first holding unit 2 and the second holding unit 3 can be easily formed. It is fixed without sliding. The practitioner can perform these displacement operations with one hand. Further, these displacement operations are simple and can be performed quickly because it is only necessary to push the displacement operation unit 12 to the rear end side in the X direction with a finger. The electric knife 20 can be used by turning on the switches 25, 25, and the living tissue can be incised by bringing the action portion 22 into contact with the living tissue. At this time, since the action part 22 of the electric scalpel 20 is disposed on the tip end side in the X direction with respect to the action part 32 of the scissors 30, the electric scalpel 20 can be used without being interrupted by the scissors 30.

  According to the surgical instrument connector 1 and the multi-function surgical instrument 10, it is possible to omit the time for changing the surgical instrument, and the operator can use the desired surgical instrument with a simple operation by holding it in one hand. Since it can be in a ready state, it is possible to quickly move to another surgical operation and shorten the operation time. The shortening of the operation time not only reduces the burden on the patient by suppressing the amount of bleeding, but also reduces the burden on all medical staff involved in the surgical operation. Further, according to the surgical instrument connector 1 and the multi-function surgical instrument 10, it is not necessary to perform a complicated operation, so the burden on the practitioner is small.

  The surgical instrument connector and multi-function surgical instrument of the present invention are not limited to the above-described embodiments, and various modifications are possible as long as the object of the present invention can be achieved.

  For example, the surgical instrument connector 1 according to this embodiment is provided with a convex portion 4 on the side surface of the base 11 provided on the upper portion 92 of the holding portion 6, and the convex portion 4 and the second holding portion 3. The guide groove 5 provided on the side surface is slidably fitted to form a parallel movement mechanism. The parallel movement mechanism causes the first holding part 2 and the second holding part 3 to be parallel to each other. Any structure can be adopted as long as it can be moved. For example, in the surgical instrument connector 100 shown in FIG. 5, a substantially prismatic protrusion 104 is provided on the upper portion 192 of the holding portion 106, and a substantially prismatic guide groove 105 is formed on the bottom surface of the second holding portion 103. These are fitted together to form a translation mechanism. The ridge 104 has a prismatic small ridge 142 on each of two surfaces facing in the Z direction. The guide groove 105 has a prismatic second small convex portion 152 on each of two surfaces facing in the Z direction. The small concave stripe portion 142 and the second small convex stripe portion 152 have shapes corresponding to each other and are fitted together. Therefore, the second holding unit 103 and the first holding unit 102 are fixed in the Y direction and the Z direction and can be slid relative to each other in the X direction.

  The surgical instrument connector 1 of this embodiment has a parallel movement mechanism as a displacement mechanism, and slides the second holding part 3 with respect to the first holding part 2. The type of the displacement mechanism is not particularly limited as long as it is a displacement mechanism that can displace the position of the working portion of the desired surgical instrument relative to other surgical instruments so that the use is not hindered. The surgical instrument connector according to the present invention may be, for example, a surgical instrument connector 200 whose displacement mechanism is a rotation mechanism, as shown in FIG. The surgical instrument connector 200 shown in FIG. 6 has a first holding part 202 and a second holding part 203. The first holding unit 202 has a U-shaped holding unit 206 that opens downward in the drawing. The second holding unit 203 includes a U-shaped holding unit 216 that opens upward in the drawing. An annular frame 204 is provided on the outer peripheral surface of the wall 292 facing the opening of the hold unit 206. A spherical sphere 205 is provided on the outer peripheral surface of the wall portion 294 facing the opening of the hold portion 216. In this surgical instrument connector 200, a frame 204 and a sphere 205 are fitted together to form a rotation mechanism that can be rotated and moved around the Y axis.

  The surgical instrument connector according to the present invention may be a surgical instrument connector 300 whose displacement mechanism is a parallel crank mechanism, as shown in FIG. The surgical instrument connector 300 shown in FIG. 7 has a first holding part 302 and a second holding part 303. The first holding unit 302 has a U-shaped holding unit 306 that opens downward in the drawing. The second holding unit 303 includes a U-shaped holding unit 316 that opens upward in the drawing. A first fulcrum pin 355 and a second fulcrum pin 356 are provided on the outer peripheral surface of the wall 392 facing the opening of the first holding unit 302. A third fulcrum pin 345 and a fourth fulcrum pin 346 are provided on the outer peripheral surface of the wall portion 394 facing the opening of the hold portion 316. A first bar 361 is provided to connect the first fulcrum pin 355 and the third fulcrum pin 345, and a second bar 362 is provided to connect the second fulcrum pin 356 and the fourth fulcrum pin 346. Accordingly, the first holding unit 302 and the second holding unit 303 are connected to each other. The first fulcrum pin 355 to the fourth fulcrum pin 346 are provided so as to be rotatable about the Y axis. The first fulcrum pin 355 to the fourth fulcrum pin 346, the first rod 361, and the second rod 362 form a parallel crank mechanism. As shown in FIG. 7B and FIG. 7C, the first rod 361 and the second rod 362 are rotated in parallel on the XZ plane by the parallel crank mechanism, and with respect to the first holding portion 302. Since the position of the 2nd holding | maintenance part 303 can be displaced, the position of the action part in the surgical instrument each hold | maintained at these can be displaced.

  In the surgical instrument connector 1 of this embodiment, the holding part 6 of the first holding part 2 has a shape obtained by bending a belt-like body into a substantially U-shape, but the surgical instrument is fixed to the first holding part. As long as it is done, the fixed form is not particularly limited. The shape of the first holding part can be appropriately set according to the shape of the operation part of the surgical instrument. For example, in the case where the operation portion is rod-shaped, the hold portion may be formed in an annular shape by a member having elasticity, and the rod-shaped operation portion may be fixed. Moreover, the form which fixes an operation part to a plate-shaped hold part, for example using a screw | thread etc. may be sufficient. The first holding part may have the same shape as the second holding part.

  In the surgical instrument connector 1 of this embodiment, the scissors 30 are fixed to the inclined step portion 7 provided in the second holding part 3, but as long as the surgical instrument is fixed to the second holding part. The fixing form is not particularly limited. The shape of the second holding part can be appropriately set according to the shape of the operation part of the surgical instrument. For example, the surgical instrument connector 100 shown in FIG. 5 has a groove 107 in the upper part of the second holding part 103 which is a substantially prismatic body. The surgical instrument connector 100 can fix the scissors 30 by disposing one of the operation portions 33 of the scissors 30 in the groove 107. Further, the surgical instrument connector 200 shown in FIG. 6 has a U-shaped holding portion 216 that opens upward in the drawing. A rod-like operation part can be fitted into the holding part 216 and fixed. The second holding part may have the same shape as the first holding part.

  The surgical instrument connector 1 of this embodiment connects two surgical instruments, ie, the electric knife 20 and the scissors 30, but the number of surgical instruments to be coupled is not particularly limited, and at least two different functions are connected. Surgical instruments can be connected.

In the scissors 530, the driving wire 519 is fixed to the pulley 534, and the pair of cutting blades 535 and 535 are formed to open and close by the advancement and retraction of the driving wire 519. In the scissors 530 of this embodiment, the operation portion 533 extending to the opposite side of the cutting blade 535 with respect to the pulley 534 has a rod shape. Therefore, as a 2nd holding | maintenance part holding the scissors 530 of this embodiment, the 2nd holding | maintenance part which has a holding | maintenance part which has a U-shaped shape shown in FIG.6 and FIG.7 can be illustrated.

  In a medical robot system, for example, when performing surgery using multiple types of surgical instruments as manipulators, if the number of surgical instruments to be used is greater than the number of existing arms, the manipulator is removed from the arms during the surgery. It is necessary to remove and install another type of manipulator. When the multi-function surgical instrument of the present invention is used as a manipulator, a plurality of different surgical operations can be performed with a single manipulator, so that the number of manipulators to be used can be reduced. The number of exchanges can be reduced. Therefore, by using the multi-function surgical instrument of the present invention as a manipulator, the operation time by the medical robot system is shortened, and operation errors of the medical staff are suppressed, thereby the patient and the medical staff. Can be reduced.

  Further, in the above embodiment, the case where the surgical instrument connector 1 is used as the multifunctional surgical instrument 10 that is used by the practitioner by holding two surgical instruments and holding them in hand has been described with reference to FIG. As shown, a multifunctional surgical instrument that connects a plurality of surgical instruments via the surgical instrument connector of the present invention can also be used as an endoscopic surgical instrument.

  The configuration of the endoscopic surgical instrument is not particularly limited as long as it can be operated with the multifunctional surgical instrument of the present invention. For example, as shown in FIG. 10, an endoscopic surgical instrument 600 has a multifunction surgical instrument 610 attached to the distal end of a guide pipe 614 and a control unit 617 at the rear end. Similar to the multi-function surgical instrument 510 mounted on the medical robot system 500 shown in FIG. 8, an operation for displacing the position of a desired surgical instrument relative to other surgical instruments, for example, an electric knife power source Various operations such as an operation of turning on and off, and an operation of opening and closing a pair of cutting blades in the scissors can be performed by the control unit 617.

  In an endoscopic operation, an abdominal wall or the like is incised to form a plurality of holes, a trocar is inserted into the holes, and a surgical instrument such as an endoscope or forceps is inserted through the trocar. In order to reduce the burden on the patient, the number of holes incised is kept to a minimum. Therefore, in endoscopic surgery, a plurality of types of surgical instruments are inserted into one hole and used. When the multi-function surgical instrument of the present invention is used as an endoscopic surgical instrument, a plurality of different surgical operations can be performed with a single endoscopic surgical instrument. The number of exchanges can be reduced. Therefore, by using the multi-function surgical instrument of the present invention as an endoscopic surgical instrument, it is possible to reduce the time required for replacement of the surgical instrument and shorten the operation time, and complicated replacement work By reducing, errors of medical staff can be suppressed, thereby reducing the burden on patients and medical staff.
