Manual ligation device

Abstract

The invention relates to the technical field of medical instruments, in particular to a manual ligation device. The manual ligation device comprises a shell, and further comprises a ligation ring, a gas pipe, a hollow adsorption pipe, a push pipe and a rotary block. The adsorption pipe is fixedly connected to the shell, and one end of the adsorption pipe protrudes out of the shell; the gas pipe isarranged on the shell and communicates with one end of the adsorption pipe; the push pipe is arranged on the shell, and one end of the push pipe protrudes out of the shell; the ligation ring sleevesthe end, which is positioned outside the shell, of the adsorption pipe; when the manual ligation device is used, the push pipe is controlled to reciprocate on the shell through a control mechanism, therefore, the ligation ring on the adsorption pipe is ligated on an internal hemorrhoid, the rotary block rotates, and telescopic protrusions are clamped in rotary guide grooves with different displacements; and because the groove depths among the rotary guide grooves are increased in sequence, the displacement stroke of the push pipe is changed, the stroke of contact between the push pipe and theligation ring on the adsorption pipe is also controlled, and misoperation of workers is prevented.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a manual ligation device. Background technique [0002] "Hemorrhoid ligation (also known as hemorrhoid rubber ring ligation, hemorrhoid suction ligation, etc.)" is a common method for the treatment of hemorrhoids. ) bandage at the root (or base) of the internal hemorrhoid, thereby using the elastic retraction force of the rubber ring to block the blood supply of the hemorrhoid, making it necrotic, shrinking, and falling off, so as to achieve the purpose of healing. In the past, the traditional instruments used for ligation surgery were extremely simple, time-consuming, laborious, and prone to complications. In order to change this situation, in the past ten years, there has been an automatic device that makes the ligation operation simple and easy, that is, the automatic hemorrhoid ligation device (also known as the continuous-fire hemorrhoid ligation device, the con...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that when the rubber ring is tied on the internal hemorrhoid, due to the operator's misoperation, multiple rubber rings will be set on the same internal hemorrhoid, which will cause waste of resources. , making it inconvenient for the staff to operate, which increases the difficulty of the operation and reduces the efficiency. A manual ligation device is now provided
