Problems solved by technology

[0002] The snare is a commonly used medical device, mainly used for the ligation of appendix residues, gallbladder residues, fallopian tubes and other cavity organs, as well as the ligation of polyps in the rectum and sigmoid colon. At present, the traditional snare method for polypectomy is too complicated and inconvenient to operate , which virtually reduces the use effect of the snare. In view of the above defects, it is necessary to design a hysteroscopic tissue snare
