Disposable haemorrhoids loop ligature device

Abstract

The invention relates to a disposable haemorrhoids loop ligature device which can especially conduct loop ligature on multiple haemorrhoids at a time and can further achieve best treatment effect by replacing a loop ligature module according to various pathogenic degrees of internal hemorrhoids, rectal internal prolapsed and other diseases. The disposable haemorrhoids loop ligature device comprises the loop ligature module, an inner sleeve, a pushing tube, a movable handle module, a fixed handle, a negative-pressure switch module, a reset insurance module, a reset spring, a connector and an adapter. The loop ligature module comprises a loop ligature head, loop ligature module rings and gaskets. The inner sleeve is installed in the pushing tube, a clamping groove is formed in the front end of the inner sleeve, and the adapter is connected to the rear end of the inner sleeve and is connected with the negative-pressure switch module through a connecting tube. The pushing tube provided with the inner sleeve is installed in a pushing tube sliding groove formed in the upper portion of the inner side of the fixed handle. The negative-pressure switch module comprises a negative-pressure switch valve body, a negative-pressure switch valve element, a negative-pressure switch handle I and a negative-pressure switch handle II. The reset insurance module comprises a reset insurance block, a reset insurance spring, a reset button and a reset spring.

Description

technical field [0001] The invention relates to a disposable hemorrhoid ligation device, especially capable of ligation of multiple hemorrhoids at the same time, and it is also possible to select and replace the ligation components for diseases such as internal hemorrhoids and rectal prolapse of different degrees to achieve the best therapeutic effect . 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 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-u...

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
