Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is that the hemorrhoid ligation device in the prior art cannot simultaneously ligate multiple hemorrhoids in the anus. Friction occurs, friction will stimulate the hemorrhoids and cause user pain, resulting in poor user experience

Embodiment 1

[0031] A hemorrhoid ligation device is described as figure 1 shown, which includes:

[0032] The ligation device body has a ligation trigger 1 and a negative pressure trigger 9;

[0033] Such as figure 2 As shown, the ligation mechanism includes a drive rod 2 that is driven back and forth, and an outer sleeve 3 that is sleeved on the outside of the drive rod 2. The end of the outer sleeve 3 is evenly distributed with the rubber ring There are several annular grooves 4 for accommodating rubber rings in matching shapes, and four sliding grooves are opened on the surface of the outer sleeve 3, and the driving rod 2 is provided with a ring corresponding to each of the rubber rings. Pushing part 5, said pushing part 5 faces a right-angled triangle with one side of said rubber ring perpendicular to the axial direction of said outer sleeve 3, said pushing part 5 is embedded in said slide groove, and pushes said rubber ring in turn The forward sleeve is placed on the hemorrhoid af...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that the hemorrhoid ligation device does not have the negative pressure suction function, and the rubber rings arranged on the outer sleeve are pushed forward by the driving rod to be sleeved on the affected part of the hemorrhoids in sequence.

Abstract

The invention relates to a hemorrhoids ligation device. The hemorrhoids ligation device comprises a ligation device body and a ligation mechanism and is characterized in that the ligation device bodyis provided with a ligation trigger; the ligation mechanism comprises a drive rod and an outer sleeve, the drive rod can be driven to telescope forwards and backwards, the outer sleeve sleeves the drive rod, the axial direction of the end of the outer sleeve is provided with a plurality of annular grooves for accommodating rubber rings, a plurality of slide grooves are formed in the surface of theouter sleeve, the drive rod is provided with push parts, each push part corresponds to one rubber ring, the push parts are embedded into the slide grooves, and the rubber rings are sequentially pushed forwards to sleeve hemorrhoids affected parts. By the hemorrhoids ligation device, the problems that a hemorrhoids ligation device in the prior art cannot simultaneously ligate multiple hemorrhoidsin the anus, the hemorrhoids ligation device needs to be inserted repeatedly, the hemorrhoids ligation device rubs with the inner wall of the anus, user pain is caused by the rubbing which irritates the hemorrhoids parts, and user experience is poor are solved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a hemorrhoid ligation device. Background technique [0002] Hemorrhoids are common and frequently-occurring diseases unique to human beings. There has always been a saying in China that "nine out of ten people have hemorrhoids". Band ligation is one of the commonly used methods to treat hemorrhoids. The principle of shedding is to tie the base of the hemorrhoid root, block the blood supply of the hemorrhoid tissue, and cause it to shrink and fall off due to ischemia. At present, the use efficiency, use cost, flexibility, user experience, safety and reliability of the instruments used for ligation of hemorrhoids are important indicators for evaluating their quality. [0003] The hemorrhoid ligation device in the prior art is a disposable product, which can only complete one ligation work and cannot complete multiple ligations at the same time. When the patient has multiple hemor...
