Abstract

The utility model provides an endoscope mucous membrane excider that can ligate a wound. The excider comprises a rubber gasket(1), a rubber gasket seat(2), a stay guy(3) and an elastic ring(4). The rubber gasket is the rubber gasket with high elasticity and is used for ligating the wound. The internal lateral of the rubber gasket is inlaid with a needle thorn(11) that is used for inserting the mucous membrane so as to fix the rubber gasket onto the wound. The rubber gasket is used for covering the rubber gasket and the elastic ring is fixed onto the end part of the rubber gasket seat also used for covering the utility model onto the front part of the endoscope. The stay guy crosses over the rubber gasket to pull down the rubber gasket form the rubber gasket seat. When in surgical operation, the utility model is arranged onto the front part of the endoscope through the elastic ring; the stay guy penetrates the pipeline of the endoscope and stretches out from the other end to insert the endoscope into human body. The mucous membrane excider presses an endoscope attractor by aiming at the position of a pathological change mucous membrane, so as to suck the pathological change mucous membrane into the rubber gasket seat to form a manual polyp. And then, through pulling the stay guy, the rubber gasket is separated from the rubber gasket seat to ligate the manual polyp form the root part, and the needle thorn is inserted into the manual polyp to fix the rubber gasket seat. At this moment, the manual polyp is cut off and the wound is ligated by the rubber gasket. Finally, with the regression of the mucous membrane edema, the rubber gasket falls off and is released together with the bowel movement. The utility model has the advantages of simple structure, easy and convenient operation, low cost, and thus can effectively prevent the bleeding or perforation these complicating diseases at the operated position from being caused.

Description

The endoscopic mucosal resection device

Technical field:

This utility model relates to the medical apparatus technical field, is a kind of endoscopic mucosal resection device that is used for excising under the scope early stage canceration of digestive tract or polyp.

Background technology:

Usually adopt the endoscopic mucosal resection art when treating early stage canceration such as esophagus, stomach and colon and polyp, that is at the scope front end esophagus cirso-looping and binding device is installed, elder generation attracts the ligation mucosa to form artificial polyp, downcuts the pathological changes mucosa with the snare high-frequency electrical then.It is easy and simple to handle, and therapeutic effect is good, and indication is wide.But, take place hemorrhage easily and complication such as perforation, even threat to life because wound exposes behind the excision pathological changes mucosa.And endoscopic mucosal resection art over-borrowing is at home and abroad carried out with existing multiple instrument combination at present, and complication is many, the expense height.

Summary of the invention:

This utility model provides a kind of wound that can make by the endoscopic mucosal resection device of ligation.It comprises cushion rubber, cushion rubber seat, elastic ring and drag wire.Cushion rubber is the very strong rubber ring of elasticity, and in order to the ligation wound, the inboard studs with the needle-like thorn, so that penetrate mucosa cushion rubber is fixed in wound.The cushion rubber seat is used to overlap cushion rubber, and elastic ring is fixed in the tail end of cushion rubber seat, this utility model is placed in the front end of scope with it.Drag wire is walked around cushion rubber, in order to cushion rubber is left behind from the cushion rubber seat.During operation, by elastic ring this utility model is installed on the scope front end, the pipeline that drag wire passes scope stretches out from the other end, and scope is inserted in the body, the endoscopic mucosal resection device is aimed at the pathological changes mucosal sites, press the scope suction pump, the pathological changes mucosa is sucked after the cushion rubber seat forms artificial polyp, the pulling drag wire makes cushion rubber rolling slippage from the cushion rubber seat, artificial polyp is lived from the root ligation, the needle-like thorn penetrates in it fixes cushion rubber, and excise artificial polyp this moment again, and wound is just tied by cushion rubber.Disappear with myxedema later on, cushion rubber comes off and discharges with stool.

This utility model is simple in structure, and is easy to operate, and expense is cheap, can effectively prevent the generation of complication such as the hemorrhage or perforation of operative site.
