Multi-shot automatic elastic thread anorectum ligation device

Abstract

The invention relates to a multi-shot automatic elastic thread anorectum ligation device. The multi-shot automatic elastic thread anorectum ligation device comprises a handle, a gun barrel, a percussion switch, a connector and a negative pressure switch, wherein the gun barrel is connected with the front end of the handle and comprises an outer sleeve tube and an inner sleeve tube; the outer sleeve tube is arranged on the periphery of the inner sleeve tube in a sleeving manner; a suction head is clamped at the front end of the inner sleeve tube; an elastic thread is arranged in the inner cavity of the handle, penetrates through the outer sleeve tube from the inner cavity of the handle and is movably sleeved on the suction head; the tightness of the elastic thread is controlled by a plurality of winding mechanisms; the plurality of winding mechanisms are arranged on the handle; after being ligated, the elastic thread is rotationally cut by a blade arranged at the front end of the gun barrel; and the blade is arranged on a limiting guide tube between the outer sleeve tube and the inner sleeve tube. The invention aims to overcome the defects in the prior art and provides the multi-shot automatic elastic thread anorectum ligation device which has multiple shots, can complete ligation by a single person and is simple in structure.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an anorectal ligation device with multiple automatic elastic threads. Background technique [0002] The anorectal ligation device uses the principle of negative pressure, and puts a special rubber ring or elastic thread on the base of the hemorrhoid or the mucosa on the hemorrhoid through a special disposable anorectal ligation device at an appropriate position. Stranding blocks the blood supply of hemorrhoids or reduces venous backflow, reduces hyperemia and hypertrophy or blood stasis of hemorrhoids, causes ischemia, atrophy, and necrosis, the ligated tissue gradually falls off, and the wound tissue repairs and heals. It is mainly suitable for the ligation treatment of various internal hemorrhoids and mixed hemorrhoids or rectal benign polyps. At present, the multiple types of elastic thread ligation devices currently available are all rod-shaped exteriors installed under the ...

AI Technical Summary

Problems solved by technology

Although the elastic thread ligation device with this structure is a multi-shot elastic thread ligation device, it cannot complete the hemorrhoid ligation operation by one person. After the hemorrhoid ligation is completed, an additional shearing device is required to cut the elastic thread, which is cumbersome to operate
