Description

[Detailed description of the invention] [Industrial application field] The present invention can be attached to the distal end of an endoscope to collect foreign matter from within the body cavity, etc., especially when the foreign matter is a magnetic material. This invention relates to a hood for collecting magnetic foreign matter that is extremely easy to remove.

[Conventional technology]

Conventionally, when a magnetic foreign object such as a battery or a piece of metal is accidentally swallowed, an endoscope is inserted into the body cavity, a forceps-shaped magnet is inserted through the forceps channel of the inserted endoscope, and a forceps-shaped magnet is inserted through the forceps channel of the inserted endoscope. This method involved attracting magnetic foreign matter, that is, magnetic foreign matter, to this forceps-shaped magnet and removing it from the body cavity.

[The problem that the idea aims to solve]

However, when using the above method, it is difficult to maintain a sufficient distance between the tip of the endoscope and the magnetic foreign object, and it is necessary to control the direction of the forceps-shaped magnet so that the magnetic foreign object is attracted to a state where it can be easily removed. The unavoidable drawback was that it was extremely difficult and time-consuming.

The present invention was developed in view of the above-mentioned drawbacks that could not be avoided with conventional techniques, and its purpose is to remove magnetic foreign objects from outside the body cavity without using forceps-shaped magnets. It is an object of the present invention to provide a hood for recovering magnetic foreign matter from an endoscope, which is capable of adsorbing magnetic foreign matter into a state where it can be easily taken out, and can extremely safely and reliably take it out of the body cavity.

[Means to solve the problem]

In order to achieve the above object, the hood for collecting magnetic foreign matter of an endoscope of the present invention has an extension part formed by extending forward a part of the hood body made of an elastic material attached to the distal end of the endoscope. A magnet for attracting magnetic foreign matter is provided on the inner surface side of the body so that the adsorption state of the magnetic foreign matter can be observed.

[Effect]

The magnetic foreign body recovery hood of the present invention, which is used by being attached to the tip of an endoscope, has the above-described structure, and uses the elasticity of the hood body to attach to the tip of the endoscope. If it is attached with consideration to the field of view of the observation optical system, it will not fall off unnecessarily, and it will be formed by extending a part of it.
The extension part, which allows observation of the adsorption state of magnetic foreign objects by the magnetic foreign object adsorption magnet provided on the inner surface, is oriented in the same direction as the distal end of the endoscope, so there is no possibility of it entering the body cavity, etc. There is no inconvenience when inserting the hood, and it can be used in the same way as conventional hoods of this type.

If a magnetic foreign object such as a battery or a piece of metal is accidentally swallowed, the insertion section of the endoscope with the hood for collecting magnetic foreign objects of the present invention attached to the tip of the endoscope as described above should be removed. When inserted into a body cavity, the magnetic foreign body collection hood, which has an extension part with a magnet for magnetic foreign body adsorption installed on the inner surface, will collect the magnetic foreign body, taking into consideration the field of view of the observation optical system of the endoscope. Since it is attached to the tip so that the suction state can be observed, even if this endoscope is not equipped with a forceps channel, it can be used to search for magnetic foreign objects by manipulating the curved part, and to detect magnetic foreign objects. It has become extremely easy to attach the magnetic foreign object according to its shape, and it has become possible to remove the magnetic foreign object from the body cavity together with the insertion section of the endoscope very easily, safely, and reliably after the magnetic foreign object has been adsorbed.

In addition, it has become possible to extract foreign objects stuck in mucous membranes or the like within a body cavity and to take them out of the body cavity. At this time, an endoscope equipped with a single forceps channel may be used as the endoscope, and the insertion section with the magnetic foreign body collection hood of the present invention attached to the tip of the endoscope is inserted into the body cavity. When the tip of the extending part of the magnetic foreign body recovery hood reaches the mucous membrane part where the foreign object is stuck, when the tip of the extending part touches the mucous membrane part and presses the mucous membrane part, the endoscope The distal end of the endoscope does not swing unnecessarily, and the distance between the distal end of the endoscope and the mucous membrane is maintained at a predetermined distance, making it extremely easy and reliable to grasp and remove foreign objects with forceps. It has now become possible to take it out of the body cavity extremely easily, safely, and reliably.

At this time, if the foreign object is a magnetic material such as a metal piece,
When removing a magnetic foreign object from a body cavity, such as when removing a magnetic foreign object from a body cavity while simultaneously pulling out the insertion section of an endoscope, If the other end is attached to the magnet for attracting magnetic foreign matter provided on the inner surface of the extension of the hood for collecting magnetic foreign matter in the same manner as described above, it will be easier to remove the foreign matter from the body cavity. And it can be done safely and reliably.
