Background technique

[0002] polypectomy is performed gastrointestinal endoscopic polypectomy surgery and other commonly used medical devices. The basic structure of the existing snare is: Set ring ring can slip on the pipe handle, the handle of the front end of the tubular sheath with a flexible tail end fixedly connected with the formation of the conductive elastic ring ring at both ends of the wire loop connection elastic wire loop handle extends to the front end by a tubular flexible sleeve. When the removal of polyps, flexible sleeve endoscopic clamp Road entered into the body of disease site. When the ring ring relative to the handle is moved forward, the front end of the elastic loop wire protruding from the flexible sleeve and automatically trap formed by the elastic expansion of the role. With the endoscopic observation, the trap set in the polyp, and then gradually moved rearward ring ring relative to the handle, the trap will be gradually reduced until it sets tight polyp, then the elastic metal wire electrically heated, polyps from normal tissue solidification removed. However, endoscopic workers found that removal of polyps in use, the insulating layer is easily displaced, resulting in the local co-ram exposed, so that the high-frequency surgical device used in conjunction with the process is likely to have some non-essential burns for doctors and patients increases risk of use.
