<First Embodiment>
In the embodiment shown in FIGS. 1 to 9, the present invention is applied to an apparatus used for a method of lifting and excising a lesion using a magnetic anchor that is conventionally known as an aspect of an operation using an endoscope. It is.
FIG. 1 shows an endoscope gripping device 1 inserted into an endoscope 2 capable of observing and treating a lesion (target site) 130 (see FIGS. 5 to 9) of a patient (target). Indicates the state. The endoscope 2 includes an insertion portion 3 to be inserted into a patient's body, a distal rigid portion 60 disposed at the distal end portion of the insertion portion 3, and a treatment instrument such as an endoscope gripping device 1 behind the insertion portion 3. A forceps insertion opening 90 and a forceps channel 61 (see FIG. 5) communicating between the forceps insertion opening 90 and the distal end rigid portion 60.

As shown in FIGS. 2 and 3, the endoscope gripping device 1 is provided along a hollow cylindrical introduction tube 70 inserted into a forceps channel 61 (see FIG. 5) and an inner wall of the introduction tube 70. A pusher member 71, an operation wire 80 inserted inside the pusher member 71, a magnetic anchor 30 fitted to the distal end portion of the introduction tube 70, and a grasping forceps unit 100 disposed behind the magnetic anchor 30.

  The magnetic anchor (anchor) 30 is made of a magnetic material, and a part of the magnetic anchor (anchor) 30 is fitted to the distal end portion of the introduction tube 70. As the magnetic material used for the magnetic anchor 30, magnets such as platinum magnet, rare earth magnet, terbium, dysprosium, iron alloy, etc. can be used in addition to pure iron and iron alloy. Further, the surgeon generates a magnetic field from outside the patient's body toward the magnetic anchor 30 by using a magnetic induction member such as an electromagnet or a permanent magnet.

The grasping forceps unit 100 includes a grasping clip (gripping member for endoscope) 10 and an outer tube 40, and is disposed on the inner side of the introduction tube 70 and behind the magnetic anchor 30.
The grip clip 10 is bent into a substantially U shape, and includes a pair of arm portions 11 and 12 and a wire hooking portion 10a. The arm parts 11 and 12 are long plate-shaped, and are opposed so that they can be opened and closed. The wire hooking portion 10a is a bent portion.

  A pair of claw portions 11a and 12a bent inward are formed at the distal ends of the arm portions 11 and 12 opposite to the wire hooking portion 10a. As shown in FIG. 4, when the arms 11 and 12 are closed at the ends of the claw portions 11a and 12a at both ends in the width direction (a direction perpendicular to the opening and closing direction of the arms 11 and 12), respectively. A contact portion 13 (13a, 13b) and a contact portion 14 (14a, 14b), which are flat surfaces that contact each other, are formed. The contact planes of the contact portions 13 and 14 are located on the same plane.

Between the pair of contact portions 13 and 14, a gap portion (gripping space) 15 having a gate shape (a U-shape) is formed. That is, the gap 15 includes a pair of linear gaps 15a extending in a direction intersecting with the plane connecting the contact parts 13 and 14 as one end, and the other end of the pair of linear gaps 15a. The connecting gap 15b is connected.
The gap portion 15 having the above portal shape does not come into contact with each other even when the arm portions 11 and 12 of the grip clip 10 are closed and the contact portions 13 and 14 are brought into contact with each other.

  At the same position in the longitudinal direction of the arms 11 and 12, the arms 11 and 12 are bent so that the protrusions 11b and 12b protrude outward from the front and rear portions thereof, and the front ends of the protrusions 11b and 12b. In addition, inclined portions 11c and 12c that spread outward again from the front, and flat front end portions 11d and 12d that extend from the front ends of the inclined portions 11c and 12c to the claw portions 11a and 12a are provided. For this reason, the nail | claw parts 11a and 12a open and close by pulling the arm parts 11 and 12 in the outer cylinder pipe | tube 40, and can grasp the lesioned part 130 inside a patient. Note that the grip clip 10 may have three or more arm portions as long as the lesioned portion 130 can be gripped.

In the gripping clip 10, rear portions 11e and 12e located in the vicinity of the wire hooking portion 10a are held in a substantially cylindrical outer tube 40. The outer tube 40 has an inner diameter with which the outer surface of the grip clip 10 can come into contact, and can be formed of, for example, a stainless steel pipe, a plastic tube, or a superelastic alloy. The outer tube 40 is located in the large diameter portion 46 into which the wire latching portion 10 a and the rear portions 11 e and 12 e of the grip clip 10 are inserted, the small diameter portion 47 provided behind the large diameter portion 46, and the small diameter portion 47. The cylindrical shape has a pair of slits 41 and 42 opposed in the radial direction, and is movable relative to the grip clip 10 in the axial direction. The slits 41 and 42 extend in parallel to the axis of the outer tube 40, and the rear ends thereof are open.
Therefore, the outer tube 40 moves in the axial direction and controls the opening angle of the grip clip 10 by changing the relative position with the grip clip 10. In addition, the slit provided in the small diameter part 47 may be one.

  The magnetic anchor 30 and the grasping clip 10 (gripping forceps unit 100) are connected by a connecting member 20 having flexibility. The connecting member 20 is provided at one end of the magnetic anchor 30 after passing through the inside of the wire hooking portion 10 a and being disposed outside the outer tube 40 (gripping forceps unit 100) via the slits 41 and 42. The hole 31 is inserted and fixed. As the connecting member 20, for example, a surgical suture, a fishing line, or a metal wire can be used.

  The operation wire 80 is inserted into the introduction tube 70 so as to be capable of being pulled, and a hook member 81 is provided at the tip thereof. The hook member 81 is fixed to the operation wire 80 by a joining means such as an adhesive, solder, or brazing. The operation wire 80 is sufficiently longer than the introduction tube 70, and the rear end portion of the operation wire 80 further extends from the introduction tube 70 protruding outward from the forceps insertion port 90 of the endoscope 2. A concave portion 82 is formed in the central portion of the hook member 81.

A loop wire 50 is hooked between the recess 82 of the hook member 81 and the wire hooking portion 10a of the grasping forceps unit 100. The loop wire 50 is made of a material that is cut when pulled by a strong force of a predetermined level or more, for example, a synthetic resin material or a metal material.

On the inner wall of the introduction pipe 70, a hollow cylindrical pushing member 71 is disposed in the longitudinal direction of the introduction pipe 70. The push-out member 71 can move relative to the introduction tube 70 and pushes out the grasping forceps unit 100 and the magnetic anchor 30 from the introduction tube 70. A regulating tube 72 is fixed to the distal end of the pushing member 71 on the distal end hard portion 60 side by a fixing means such as an adhesive, solder, or brazing.

The restriction tube 72 is provided with a stepped portion 73, and a front portion 74 and a rear portion 75 are provided in the front-rear direction thereof. The outer diameter of the front portion 74 is substantially the same as the inner diameter of the introduction tube 70. On the other hand, the outer diameter of the rear portion 75 is smaller than that of the front portion 74 and is substantially the same as the inner diameter of the hollow cylinder formed by the pushing member 71. Therefore, when the extrusion member 71 is fixed to the outer periphery of the rear portion 75, the outer periphery of the hollow cylinder formed by the extrusion member 71 and the outer periphery of the front portion 74 are substantially on the same plane. The inner diameter of the front portion 74 is set larger than the inner diameter of the rear portion 75. Furthermore, the inner diameter of the front portion 74 is substantially the same as the outer diameter of the small diameter portion 47 of the outer tube 40.

Prior to introducing the magnetic anchor 30 and the grasping forceps unit 100 into the body of the patient, the grasping forceps unit 100 and the magnetic anchor 30 are disposed in the introduction tube 70 as follows.
The grasping forceps unit 100 and the magnetic anchor 30 are connected via the connecting member 20. The loop wire 50 is passed through the grip clip 10 in advance, and one end is hooked on the recess 82 of the hook member 81.

In this state, the rear end portion of the outer tube 40 is inserted into the restriction tube 72. This insertion operation ends when the stepped portion 45 of the outer tube 40 and the tip of the front portion 74 abut against each other, and the insertion of the outer tube 40 is restricted. In this way, the claws 11 a and 12 a of the grasping clip 10 are arranged so as to face the distal end side of the distal end rigid portion 60, and the grasping forceps unit 100 is accommodated in the introduction tube 70. Next, a part of the magnetic anchor 30 is fitted to the distal end portion of the introduction tube 70. Then, the introduction tube 70 is disposed in the insertion portion 3 of the endoscope 2 by being inserted into the forceps channel 61 from the forceps insertion port 90. When the magnetic anchor 30 is larger than the forceps insertion opening 90, the introducer 70 is inserted in advance from the forceps insertion opening 90 and protrudes from the distal end of the endoscope 2. In this state, the grasping forceps unit 100 can be accommodated in the introduction tube 70, and a part of the magnetic anchor 30 can be fitted to the distal end portion of the introduction tube 70.
Further, since the connecting member 20 has a sufficient length so as not to prevent the magnetic anchor 30 from being placed in front of the gripping clip 10, the magnetic anchor 30 and the gripping forceps unit 100 (the gripping force) when the insertion operation is completed. The clip 10 and the outer tube 40) are arranged in a straight line.

5 to 9 show an operation of introducing the magnetic anchor 30 and the grasping forceps unit 100 into the body, an operation of grasping the lesioned part 130 by the grasping clip 10, an operation of separating the grasping forceps unit 100 and the magnetic anchor 30, and a magnetic anchor 30 (lesion). Part 130).

The operation of introducing the grasping clip 10 and the magnetic anchor 30 into the patient's body is performed as follows. First, the insertion part 3 of the endoscope 2 is inserted into the patient's body. Thereafter, the distal end portion of the introduction tube 70 is exposed from the distal end rigid portion 60 to the inside of the body. The magnetic anchor 30 and the grasping forceps unit 100 are pushed out from the introduction tube 70 by the pushing member 71.
That is, when the regulating tube 72 is urged forward by the pushing member 71, the grasping forceps unit 100 is pushed forward. Then, the tip of the grip clip 10 of the grip forceps unit 100 comes into contact with the rear end of the magnetic anchor 30. From this state, when the restriction tube 72 is further urged forward, the magnetic anchor 30 fitted to the distal end portion of the introduction tube 70 is released. In addition, it is also possible to remove the magnetic anchor 30 fitted to the distal end portion of the introduction tube 70 by moving the introduction tube 70 toward the forceps insertion port 90 side while holding the pushing member 71.

As shown in FIG. 5, the grasping forceps unit 100 is exposed from the distal end of the introduction tube 70 to the body of the patient, and the grasping clip 10 and the outer tube 40 of the grasping forceps unit 100 are aligned in the longitudinal direction of the introduction tube 70. Placed in. The magnetic anchor 30 hangs downward due to gravity. Therefore, if the endoscope 2 is operated so that the distal rigid portion 60 faces the lesioned part 130, the operator can easily point the distal end of the grip clip 10 toward the lesioned part 130.

As shown in FIGS. 6 and 7, the gripping operation of the gripping clip 10 to the lesioned part 130 is performed as follows.
First, the operation wire 80 is moved relative to the pushing member 71 and the restriction tube 72 in order to open the flat front end portions 11d and 12d. That is, the operation wire 80 is pulled to draw the convex portions 11 b and 12 b into the outer tube 40. The convex portions 11b and 12b drawn into the outer tube 40 are in contact with the inner wall of the outer tube 40 and bend in a direction approaching each other. When the convex portions 11b and 12b are bent in this way, the flat front end portions 11d and 12d are separated from each other, and the front end side of the grip clip 10 exposed from the outer tube 40 is opened (FIG. 6).

The gripping clip 10 opened in this manner is moved toward the lesioned part 130 by moving the pusher member 71, the restriction tube 72 and the operation wire 80 together so that the relative position between the gripping clip 10 and the outer tube 40 is not changed. To proceed. When the tip of the grip clip 10 has reached a desired position, the grip clip 10 is closed. In order to close the gripping clip 10, the operation wire 80 is pulled again and moved relative to the pushing member 71 and the restriction tube 72.
If it operates in this way, since the inclination parts 11c and 12c of the holding | grip clip 10 will be drawn in in the outer cylinder pipe 40 and will contact | abut to the inner wall of the outer cylinder pipe 40, they will bend in the direction which approaches mutually. Accordingly, the flat front end portions 11d and 12d move so as to approach each other, and the front end side of the grip clip 10 exposed from the outer tube 40 is closed (FIG. 7). When the grip clip 10 is closed, the claw portions 11a and 12a at the tips of the arm portions 11 and 12 grip the lesioned portion 130. A part of the lesioned part 130 grasped by the claw parts 11 a and 12 a is accommodated in the gap part 15. In this way, the grasping operation of the grasping forceps unit 100 and the magnetic anchor 30 to the lesioned part 130 is completed. During this gripping operation, the tips of the claw portions 11a and 12a come into contact with flat contact portions 13 and 14, and a gap portion (gripping space) 15 is formed between both contact portions. And the lesioned part 130 is not easily removed.

  Next, the separation operation of the grasping forceps unit 100 and the magnetic anchor 30 is performed as follows. When the loop wire 50 is pulled strongly through the operation wire 80 and the hook member 81, the loop wire 50 is cut (FIG. 8). When the loop wire 50 is cut, the magnetic anchor 30 and the grasping forceps unit 100 restrained by the hook member 81 are released from the hook member 81. Thereafter, the push-out member 71, the regulation tube 72, the operation wire 80 and the loop wire 50 are retracted into the introduction tube 70, and are removed from the forceps insertion port 90 together with the introduction tube 70.

  Next, the excision process of the lesioned part 130 using the endoscope grasping apparatus 1 will be described. First, physiological saline is injected from the periphery of the lesioned part 130 with an injection needle inserted into the submucosal layer (not shown), and the lesioned part 130 is lifted from the proper muscle layer (not shown).

  On the other hand, a magnetic induction member (not shown) made of an electromagnet is arranged at a preset position outside the patient. When the magnetic anchor 30 is set up in this way and lifted by the attractive force of the magnetic induction member, the lesioned part 130 is lifted together with the magnetic anchor 30 (see FIG. 9). That is, when power is applied to the magnetic anchor 30 by the external magnetic field of the magnetic guiding member, the operator can pull the grasping clip 10 in a desired direction by suction control of the magnetic anchor 30 and lift the lesioned part 130. Can do. When the amount of lifting of the lesioned part 130 is insufficient or too large, adjustment is performed by shifting the position of the magnetic induction member or weakening the magnetic field generated by the magnetic induction member.

  Subsequently, an incision tool such as a high-frequency knife is introduced into the body through the forceps channel 61, and the lesioned part 130 is excised from the end together with the mucous membrane. At this time, since the lesioned part 130 is lifted by the grip clip 10, a sufficient excised part can be taken, and the already excised lesioned part 130 can also be prevented from falling on the proper muscle layer. Further, the excised lesioned part 130 can be further lifted by gradually shifting the position of the magnetic induction member (not shown). The surgeon can easily confirm the tip position of the high-frequency knife and can perform excision smoothly.

  When the excision work is finished, the magnetic anchor 30 is drawn to the magnetic guiding member while the grasping clip 10 grasps the lesioned part 130. Therefore, it is possible to prevent the excised lesion part 130 from being lost. When the lesioned part 130 is collected, for example, grasping forceps (not shown) or the like is introduced into the body via the forceps channel 61 and the grasping forceps unit 100, the magnetic anchor 30 or the connecting member 20 that grasps a part of the lesioned part 130 is used. Grip either of them with grasping forceps. In this state, the supply of current to the magnetic induction member is stopped. It collect | recovers by removing the insertion part 3 of the endoscope 2 as it is. Thereafter, treatments such as suturing and disinfection are performed.

  Since the nail | claw part 11a, 12a has the clearance gap part 15, the lesioned part 130 is not bitten. Therefore, the claw portions 11a and 12a can reliably hold the lesioned portion 130 until the collection operation is completed regardless of the amount of lifting by the magnetic guide member and the pulling direction of the magnetic anchor 30.
