入させている。2. Description of the Related Art In an endoscope for observing the inside of a body cavity and performing a treatment, a forceps as shown in FIG. 4 is inserted into a treatment instrument insertion port 100A on the hand operation unit 100 side of the endoscope shown in FIG. The one equipped with the stopper 101 has been developed. This forceps stopper 101
It is composed of a hollow cylindrical main body 101A, and a stretchable plug 101B fitted to an opening of the main body 101A, and a cut hole 1 formed in the plug 101B.
01C is expanded to insert forceps (not shown) or the like. By the way, this endoscope is sterilized and disinfected before or after use, and is used again, for example, for disinfection of a forceps tube (not shown) constituting a forceps introduction passage communicating with a treatment port insertion port for attaching the forceps stopper. And so on. Therefore, the stopper is removed from the body of the forceps stopper, and a syringe is inserted from the opened body to allow the disinfectant to be injected into the forceps introduction passage.

鉗子栓を提供することを目的とするものである。When a syringe with a needle is mistakenly used during disinfection of the forceps introduction path or the like, and the needle of the used syringe comes off, the inner part of the narrow introduction path is disturbed. In many cases, it is difficult to get out of the room and get out. In addition, if the tip of the needle pierces the forceps tube, a pinhole may be formed, and if this pinhole is formed, inconveniences such as leakage of the cleaning solution or the like may occur, so that the pinhole may be used next time. It is not possible. In view of the above circumstances, the present invention provides an endoscope that does not enter the forceps tube even if the needle comes off from the syringe used for disinfection, and that there is no possibility that the forceps tube has a hole. It is an object of the present invention to provide a forceps stopper.

る。In other words, the forceps plug for an endoscope according to the present invention is arranged such that the opening of the forceps plug attached to the treatment instrument insertion port of the endoscope is oriented in the opening direction of the treatment instrument insertion port for attaching the forceps plug. And is configured so that when the syringe is inserted into the opening, the needle of the syringe is locked to the inner peripheral surface of the open end of the forceps plug and does not enter any further deeper. It was done.

In other words, the needle tip of the syringe is inserted through the opening. In this case, the needle is locked to the inner peripheral edge of the opening of the forceps plug, so that even if the needle comes off the syringe body, the needle remains locked in the opening. And fall from the opening to the forceps tube at the back.

The opening direction of the opening of the main body 2 (the central axis is α) is the opening direction of the treatment instrument insertion port 4A (the central axis is β) as shown in FIG. Is shifted (inclined) upward by an angle δ. The base 1 is formed in a substantially cylindrical shape and is fixed to the main body 2. As shown in FIG. 2, the base 1 is screwed into an opening 4 </ b> B that constitutes a treatment opening 4 </ b> A provided in the endoscope main body 4. And the center axis is aligned with the center axis β of the opening 4B. The main body 2 is formed in a substantially cylindrical shape, and is fixed in a state where the opening direction of the opening (center axis α) is shifted (inclined) by an angle δ with respect to the opening direction of the base 1 (center axis β). ing. The stopper portion 3 is formed of an elastic material such as rubber as in the conventional one, and is detachably mounted on the opening 2A of the main body portion 2.

When the antiseptic solution is injected into the forceps tube 5 by being inserted into the forceps tube mounting plumbing 8, the needle 7 is
Even when detached from the main body, it does not fall into the inner part of the main body 2 of the forceps stopper. That is, the needle 7 locks the expanded tapered portion 7B at the base of the needle to the edge of the inner peripheral surface 2B of the opening of the forceps plug main body 2 and prevents the needle 7 from further entering the back. Problems such as the needle tip 7A getting into the tube 5 and piercing the forceps tube 5 can be prevented.
