A one-time automatic hemorrhoid ligation device

Abstract

The invention relates to the technical field of ligation devices, and discloses a disposable automatic hemorrhoid ligation device, comprising a firing casing, a ligature rubber ring and a negative pressure joint. A movable handle is arranged in front of the handle, the negative pressure joint is arranged at the tail of the firing casing, the end of the movable handle is rotatably connected to the firing casing through a rotating shaft, a firing assembly is arranged above the movable handle, and the firing assembly It consists of a firing block and a first compression spring. Connect the negative pressure suction tube to the vacuum machine, and suck the affected part of the patient into the negative pressure cavity. When the affected part reaches the trigger rod at the end of the negative pressure cavity, move the trigger rod backward, and the doctor can pass through the transparent cover at the tail of the negative pressure suction tube. Observe the moving distance of the positioning block at the tail of the trigger rod. A scale line should be set on the outside of the transparent cover to better observe the movement of the positioning block and determine the degree of inhalation of the patient into the negative pressure lumen.

Description

technical field [0001] The invention relates to the technical field of ligation devices, in particular to a disposable automatic hemorrhoid ligation device. Background technique [0002] The ligation device is treated with pericardial vascular severing. It is popular because of its precise hemostatic effect, simple operation, and wide indications. After that, the ligation site necroses and falls off to form a small superficial ulcer, and soon dense scar tissue is formed. Thrombotic occlusion is formed inside, which has few complications and is a safe and effective endoscopic technique. Hemorrhoid ligation device is a medical device used to treat internal hemorrhoids, mixed hemorrhoids, lower sigmoid colon and rectal polyps. By using the transparent suction head of the ligation device and the push ring cylinder with a plurality of observation holes, the blind vision phenomenon during ligation can be improved, and the reliability and accuracy of the ligation can be enhanced. ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a disposable automatic hemorrhoid ligation device, which has the advantages of being able to perform secondary ligation, making the operation more perfect, and being able to accurately observe the degree of mole root inhalation, etc. A ligation can be performed once, but the degree of inhalation cannot be accurately judged
