Mucosa resecting scalpel

Abstract

The invention relates to a mucosa resecting scalpel which is composed of a scalpel head portion and a scalpel tail portion. The scalpel head portion comprises a barrel, an electric knife body and a half opening and closing device, wherein part of the electric knife body is sleeved in the barrel, and the half opening and closing device is arranged on the barrel; the scalpel tail portion comprises a sliding guide rail, an electrocoagulation knife push rod, an electric knife push rod, an electrocoagulation knife handle and an electric knife handle, wherein the electrocoagulation knife push rod and the electric knife push rod are arranged on the sliding guide rail, and the electrocoagulation knife handle and the electric knife handle control the electrocoagulation knife push rod and the electric knife push rod to move; two external insulation metal rods and an external insulation wire are arranged in the barrel, one metal rod is connected with the electric knife body to drive the electric knife body to telescopically move, the other metal rod is connected with the half opening and closing device to drive the half opening and closing device to move, and the scalpel head portion and the scalpel tail portion are connected with each other through an extensile metal hose. The mucosa resecting scalpel has double functions of the electric knife and an electrocoagulation knife, and by means of the mucosa resecting scalpel applied to an endoscope, blood of patients can be immediately stopped when mucosal tissue is resected, so that operation time is shortened, and simultaneously, operation safety is improved.

Description

technical field [0001] The invention relates to a medical appliance, in particular to an endoscopic mucosal dissection scalpel. Background technique [0002] Mucosal dissection is an emerging endoscopic treatment technique for early digestive tract cancer or precancerous lesions in recent years. Its English name is Endoscopic submucosal dissection, or ESD for short. It is a cutting-edge technology in the field of digestive endoscopy that can completely remove large lesions through mucosal dissection and achieve the effect of radical cure. [0003] However, the clinical operation of the existing mucosal dissection technology is cumbersome. Generally, the electric knife is used to remove the mucosal tissue under the endoscope, and then the electric coagulation knife is replaced to stop the patient from bleeding. This method not only takes a long time for the operation, but also reduces the incidence of complications. It is also as high as 5%-10%, and its safety needs to be im...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a new type of mucosal peeling scalpel in order to overcome the need to replace the scalpel in the above-mentioned mucosal peeling technique, which results in long operation time and low safety. function, and has the function of electrocoagulation knife, the application of the present invention under endoscope can immediately stop the bleeding of the patient when the mucosal tissue is removed, shorten the operation time, and improve the operation safety at the same time
