Automatic elastic thread hemorrhoid ligation anastomat

Abstract

The invention provides an automatic elastic thread hemorrhoid ligation anastomat, which comprises a gun barrel assembly, a gun body, a percussion tangent gear shifting device, an elastic thread tightening device, a quick connecting device and a negative pressure suction device. The gun barrel assembly is connected with the gun body; the quick connecting device is arranged at the front end part ofthe gun body and the rear end part of the gun barrel assembly; the elastic thread tightening device is arranged on the lower portion in the gun body; a percussion device is arranged on the upper rearportion of the gun body; a gear shifting device is arranged on the side face of the gun body; the percussion device and the elastic thread tightening device are combined together through the gear shifting device; and a connector of the negative pressure suction device is arranged on the lower portion of the gun body. The automatic elastic thread hemorrhoid ligation anastomat is simple in structure, and a doctor can operate the automatic elastic thread hemorrhoid ligation anastomat with one hand. A target haemorrhoids tissue is adsorbed through the negative pressure suction device; then ligation is conducted on the target haemorrhoids tissue through the percussion device and the elastic thread tightening device; and after gear shifting, the elastic thread is cut off through a cutter threadcutting device. The automatic elastic thread hemorrhoid ligation anastomat is convenient to use.

Description

technical field [0001] The invention relates to the technical field of staplers, in particular to an automatic elastic thread hemorrhoid ligation stapler. 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. The traditional instruments used to perform ligation in the past are extremely crude, time-consuming, labor-intensive, 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 li...

AI Technical Summary

Problems solved by technology

The use of rubber rings as ligation materials has some inherent disadvantages: ① Due to the inherent characteristics of natural rubber (or latex, silica gel, etc.), the inner diameter of the rubber ring cannot be infinitely small, and generally can only be made into 2.0-2.5mm ( At least not less than 1.5mm), otherwise it is easy to break when the bandage is stretched

[0011] 1) During the operation of the automatic elastic thread ligation device disclosed in this reference document, it is necessary to hold the ligation device with one hand, hold the force point with one hand, and pull the elastic thread with the other hand to reduce the inner diameter of the loop; at least two people are required to complete the operation , troublesome operation, low work efficiency

[0012] 2) The automatic elastic thread ligation device disclosed in this comparative document requires the doctor to use scissors to cut off the elastic thread after the elastic thread is tightened after the surgical operation, which is troublesome to operate and low in work efficiency

The front section of the gun barrel is not smooth enough, and it is easy to leak air when inhaling hemorrhoid tissue, which makes the hemorrhoid tissue unable to be sucked into the gun barrel smoothly
