A kind of ligation device for gastric polyp gastroscope

Abstract

The invention discloses a gastric polyp gastroscope ligator and belongs to the technical field of the gastroenterology department. The gastric polyp gastroscope ligator comprises a telescopic hose andan injection device, an endoscope device, a polyp ligation device and a ligation control device arranged in the telescopic hose, wherein the ligation control device comprises a positioning driving part and a control handle for programmed control of the positioning driving part, and the control handle is electrically connected to the positioning driving part. The observation and ligation operations in a stomach environment can be completed by putting the ligator into the body of a patient from the outside of the patient, so that the surgical steps become simple, the patient's discomfort is reduced, and the success probability of the operation is improved. By means of the polyp ligation device, the polyps and the parts of the gastric mucosa are ligated; after the polyps fall off, the gastric mucosa is directly in contact with the stomach acid, the contact between the stomach acid and the inner layer of the stomach wall is avoided, and the phenomenon of wound ulceration is avoided.

Description

technical field [0001] The invention relates to the technical field of gastroenterology, in particular to a gastroscope ligation device for gastric polyps. Background technique [0002] At present, there are many treatment methods for gastric polyps, among which endoscopic ligation is a commonly used clinical treatment method. The principle of endoscopic ligation is to use a ligation device to ligate the polyps, so that the cells cannot grow normally until The necrosis falls off to form a wound, and a new stomach wall is formed after the wound is healed. The operation of endoscopic ligation is convenient and quick, the wound is small, and the patient's acceptance is high. However, only the innermost mucosal layer of the stomach wall can resist gastric acid. In some polyps, not only the mucosal layer protrudes into the polyp bulge. In this case, the submucosa will be exposed on the wound surface of the ligation, and the ulcer will be difficult to heal. There is even a risk ...

Problems solved by technology

[0004] The object of the present invention is to provide a gastric polyp gastroscope ligation device, on the one hand, to solve the problems of inaccurate and cumbersome steps for gastric polyp ligation in the prior art; Insufficient separation can lead to technical problems with non-mucosal layers being bandaged
