Description

[Detailed description of the invention] This invention uses an endoscope to pull out foreign objects inside the body cavity, especially foreign objects such as metal pieces stuck in the mucous membranes of the body cavity or digestive organs, etc., and take them out of the body cavity. It relates to auxiliary tools that are sometimes used.

Conventionally, in order to extract a foreign object such as a metal piece stuck in the mucous membrane of a body cavity, etc. from the mucous membrane and take it out of the body cavity, an endoscope equipped with a separate forceps channel is inserted into the body cavity. The forceps inserted through one forceps channel press down on the mucous membrane, and the forceps inserted through the other forceps channel grasp a foreign object such as a metal piece and pull it out to take it out of the outer cavity.
However, when using this type of method, not only is there an inconvenience in that it is difficult to maintain a space between the tip of the endoscope and the mucous membrane, making it difficult to pull out the endoscope, but also the diameter of the flexible tube in the endoscope is large. There were also problems with size and price.

The present invention makes it extremely easy to remove foreign objects such as metal fragments stuck in the mucous membranes in body cavities, even with a conventional endoscope with a single forceps channel.
The object of this invention is to provide an auxiliary tool that allows the body cavity to be taken out of the body cavity.

That is, the aid for grasping a foreign object for an endoscope according to the present invention has a part of the main body that is intended for attachment to the distal end of the endoscope, and when this main body is attached to the distal end of the endoscope, , is formed by extending a gap forming member that protrudes in front of the tip and forms a predetermined gap between the tip and the foreign object to facilitate the operation of grasping the foreign object with the forceps. If you insert this into a body cavity, etc., and the tip reaches the mucous membrane part of the body cavity that is pierced by a metal piece, etc., it will When the distal end of the interval forming member is brought into contact with the distal end of the endoscope, the distal end of the interval forming member presses against the mucous membrane part that is being pierced by metal pieces, etc., and the distal end of the endoscope does not swing unnecessarily. By keeping the distance between the tip and the mucous membrane part at a predetermined distance, on the one hand, it becomes extremely easy to grasp metal pieces with forceps, and on the other hand, the pulling operation becomes simple and reliable, and the desired result can be easily achieved. I was able to achieve my goal.

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In the figure, A is a conventional endoscope and B is a conventional endoscope.
1 is an auxiliary device for grasping a foreign object for an endoscope according to the present invention, which is attached to the distal end portion 1 of an endoscope A, and C is a mucous membrane portion within a body cavity.

In the endoscope A, 1 is its tip, 2 is a forceps channel, 3 is a suction/forceps port, and 5 is a forceps. In addition, each end of an air and water pipe, as well as an observation optical system and an illumination optical system, are fixed to the tip 1.

Now, in B, an auxiliary tool for grasping a foreign object for an endoscope according to the present invention, 11 is a removable cylindrical body made of an elastic material for attachment to the distal end 1 of the endoscope A; A tongue-shaped space formed by extending a part of the cylindrical body 11 so as to protrude forward of the distal end 1 as shown in the figure when the cylindrical body is attached to the distal end 1. It is a member for use, and its tip 13 is bent in an upright shape.

Further, numeral 20 in the figure indicates a foreign object such as a metal piece stuck in the mucous membrane portion C.

Auxiliary tool B for grasping a foreign object for an endoscope according to the present invention
This has the above-mentioned configuration, and when it is used, as shown in the figure, the cylindrical body 11 made of elastic material is attached to the distal end 1 of the endoscope A, making use of its elasticity. If you put it on, it will not fall off unnecessarily,
Since the spacing forming member 12, which is partially extended, is oriented in the same direction as the distal end portion 1, there is no inconvenience when inserting it into a body cavity or the like.

When the distal end 1 of this endoscope A reaches the mucous membrane part C where a foreign object 20 such as a metal piece in the body cavity is stuck, the foreign object grasping member B according to the present invention attached to the distal end 1 When the distal end portion 13 of the spacing forming member 12 is brought into contact with the mucous membrane portion C, the distal end portion 13 of the spacing forming member 12 presses the mucous membrane portion C where the foreign object 20 such as a metal piece is stuck and suppresses its movement. At the same time, the distal end 1 of the endoscope A does not swing unnecessarily, and the distance between the distal end 1 and the mucous membrane C is maintained at a predetermined distance. This makes it extremely easy to hold the handle and, on the other hand, makes the pulling operation simple and reliable.

As is clear from the above description, although the structure of the aid for grasping a foreign object for an endoscope according to the present invention is extremely simple, it is possible to use a Even foreign objects such as fragments can now be extracted extremely easily and reliably using a single forceps channel and a conventional endoscope, and can be taken out of the body cavity.

A: endoscope, 1; tip end, B: aid for grasping a foreign object for endoscope according to the present invention, 11; cylindrical body made of elastic material, 12; gap forming member, 13; tip end,
C: Mucosal area, 20: Foreign object such as a metal piece stuck in the mucous membrane area.

Claims (1)

[Scope of utility model registration request] When the main body is attached to the distal end of an endoscope, a part of the main body that is provided for attachment to the distal end of the endoscope protrudes in front of the distal end and prevents contact between the distal end and a foreign object. 1. An auxiliary tool for grasping a foreign object for an endoscope, characterized in that a distance forming member is extended to form a predetermined interval between the members and facilitate the operation of grasping the foreign object with forceps.
