Problems solved by technology

[0004] The transparent tube and the rubber ring (or ligation thread) of the traditional internal hemorrhoid ligation device operate independently. One doctor needs to operate the transparent tube to absorb the target and fix the position at the same time, and another doctor performs the ligation (and cuts the ligation thread). The narrow space leads to It is extremely inconvenient to operate, and the rubber ring is easy to break and the tightening force is not enough, so we are looking for a hemorrhoid ligation device with convenient operation and strong tightening force, which can be completely operated by one doctor with one hand

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hemorrhoid ligation device for anorectal department with one-hand tight thread and broken thread. Background technique [0002] Department of Anorectal is a department specializing in the treatment of constipation, anal fissure, anal fistula, anal abscess, anal stenosis, anal nipple hypertrophy, perianal eczema, mixed hemorrhoids, internal hemorrhoids, and external hemorrhoids. The disease occurred between the anus and the rectum 8-12cm. [0003] In the prior art, the internal hemorrhoid ligation device is a medical device used to treat internal hemorrhoids, mixed hemorrhoids, lower sigmoid colon and rectal polyps. The transparent tube suction head of the ligation device is used to absorb the target, and a special rubber ring is placed on the hemorrhoid or hemorrhoid. The base of the mucosa on the hemorrhoids can block the blood supply of hemorrhoids or reduce venous backflow th...
