Disposable ligation device for anorectal hemorrhoids

Abstract

The invention relates to a disposable ligation device for anorectal hemorrhoids. Particularly, multiple hemorrhoids can be ligated, and replaceable rotatable ligation assemblies can also be selected for the hemorrhoids different in degree, internal rectal prolapse and other anorectal diseases to achieve the best treatment effect. The device comprises a rotatable ligation assembly, a ligation assembly connection fixing device, a negative pressure tube assembly, a trigger and a shell; the rotatable ligation assembly comprises an elastic thread loop, a push tube, a suction tube, a long tube, a rotary knob and an elastic thread component; the shell is composed of a left shell body and a right shell body, the front portions in the left shell body and the right shell body are internally provided with locking hoop guide grooves and spring positioning baffles, and the middles in the left shell body and the right shell body are arranged in a connection fixing device mounting groove; the ligation assembly connection fixing device comprises a trigger tube, a locking hoop, a spring, a spring base, a catch button, a catch button connector, a push button and a seal ring; the negative pressure tube assembly comprises a two-way tube, a three-way tube, an air tube connector, a silicone tube and a negative switch.

Description

technical field [0001] The invention relates to a disposable anorectal hemorrhoid ligation device, especially capable of ligation of multiple hemorrhoids, and can also select replaceable and rotatable ligation components for anorectal diseases such as hemorrhoids of different degrees and rectal prolapse to achieve Optimum therapeutic effect. Background technique [0002] Hemorrhoids are common diseases held by human beings, frequently-occurring diseases, and 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 instruments used to ligate hemorrhoids are mainly two types: suction and pull. The device is complicated and the operation is troublesome. The metal pull type is a multiple-use p...

AI Technical Summary

Problems solved by technology

At present, the instruments used to ligate hemorrhoids are mainly two types: suction and pull. The device is complicated and the operation is troublesome. The metal pull type is a product for multiple use, which is easy to be sterilized and will cause cross-infection.

There is a ligation device that uses the ratchet wheel to rotate and pull the silk thread to drive the elastic ring to ligate, and the operation is cumbersome

[0003] At present, the ligation head of the hemorrhoid ligation device is fixed on the inner sleeve and cannot be rotated. When the hemorrhoids are sucked and ligated during surgery, the direction of the suction ligation head cannot be changed. It is difficult to suck and ligate different parts of the anorectal hemorrhoid tissue, and the line of sight is unclear. , the position of the entire ligation device must be adjusted repeatedly, which is very inconvenient for medical staff to operate, prolongs the operation time, and brings pain to the patient
