Hemorrhoids ligation device

Abstract

The invention discloses a hemorrhoids ligation device. The hemorrhoids ligation device is used for solving the technological shortcomings that the operation of the existing ligation device is troublesome, the operation time is long, and an elastic rubber ring cannot be uniformly looped at the root part of hemorrhoid. The adopted solution is as follows: a hemorrhoids ligation device comprises a hemorrhoids ligation part and a hemorrhoids ligation control part; the hemorrhoids ligation control part comprises a handhold ligation device shell, a suction piston control slide plate, a variable-speed reversing gear, a suction piston control trigger, a ligation rubber ring pushing cylinder control slide plate, and a ligation rubber ring pushing cylinder control trigger. The suction piston control trigger controls the suction piston through a gear transmission, the ligation rubber ring pushing cylinder control trigger controls a ligation rubber ring pushing cylinder through the gear transmission to realize the ligation of the root part of the hemorrhoid by using the ligation rubber ring. The hemorrhoids ligation device is simple in structure, quick and convenient to use, and exact in the ligation position.

Description

technical field [0001] The invention relates to a medical device, in particular to a hemorrhoid ligation device which uses an elastic rubber ring to ligate the root of the hemorrhoid when treating hemorrhoids. Background technique [0002] In the prior art, ligation of hemorrhoids has become a standardized treatment method. One of the ligation methods used is manual ligation, and the other is to use a ligation device. The ligation device adopts a negative pressure hemorrhoid suction tube and a suction piston. It is composed of a rubber ring pusher with a ligated rubber ring. One end of the negative pressure hemorrhoid suction tube faces the lesion of the hemorrhoid. The rubber ring pusher set outside the negative pressure hemorrhoid suction tube pushes the rubber ring on the outer circle of the front end of the negative pressure hemorrhoid suction tube into the root of the hemorrhoid, and the root of the hemorrhoid is tied tightly by the elastic contraction of the rubber rin...

AI Technical Summary

Problems solved by technology

[0004] There is also a hand-held ligation device in the prior art. The ligation device relies on negative pressure to suck the negative pressure of the lesion into the hemorrhoid suction tube, and then sends the elastic rubber ring into the root of the hemorrhoid through a pull wire. The disadvantage of this structure is that the pull wire When controlling the elastic apron, the elastic apron is prone to deformation, and the elastic apron cannot be evenly ligated on the root of the hemorrhoid, which affects the treatment effect. At the same time, the structure of the existing ligation device is complex
