Integrated full-single-hand operation selective hemorrhoid elastic thread ligator

Abstract

The invention relates to an integrated full-single-hand operation selective hemorrhoid elastic thread ligator, in particular to a hemorrhoid elastic thread ligator. The hemorrhoid elastic thread ligator comprises a gun body, a gun barrel, elastic threads, fisherman knots, a negative-pressure connecting hose, a ligator handle, a trigger and a negative-pressure control switch, wherein an inner cavity of the gun barrel is provided with a sealing ring and a sleeve pipe, one end of the sleeve pipe is connected with one end of a connecting rod, the other end of the connecting rod is provided with asleeve cylinder conversion button, the rear top of an inner cavity of the gun body is provided with a large thread-tightening gear, a protruding block with hooks is coaxially arranged on the large thread-tightening gear, outer circular sleeves are arranged on the periphery of the protruding block with hooks, one ends of the elastic threads are arranged on hooks of the outer circular sleeves, the other ends of the elastic threads are arranged at the front end of the gun barrel, a thread-cutting connecting rod apparatus is arranged at the upper part of a shell of the gun barrel, and the thread-cutting connecting rod apparatus is connected with the trigger through a thread-cutting connecting rod. The hemorrhoid elastic thread ligator has the advantages that the integrated circulation percussion is realized, the repeated assembly is not needed, the operation time is saved, the operation stability is improved, the full-single-hand operation is realized, the other hand can be vacated for auxiliary operations, and the labor cost is saved.

Description

technical field [0001] The invention relates to a hemorrhoid elastic thread ligation device, in particular to an integrated all-one-handed selective hemorrhoid elastic thread ligation device with adjustable casing aperture. Background technique [0002] At present, the ligation devices or elastic threads on the market all have a fixed aperture, and the capacity is also constant. The present invention adjusts different apertures according to the size of the hemorrhoids through the cannula with variable apertures, and realizes different cures for different hemorrhoids. idea. [0003] In addition, the ligatures or elastic threads on the market realize circular firing through the separate assembly of parts and gun bodies. At the same time, both hands are required to cooperate with firing. The operation process is cumbersome and requires the cooperation of assistants to fix them. However, the present invention can realize integrated cyclic firing without repeated assembly, save ...

Problems solved by technology

[0003] In addition, the ligatures or elastic lines on the market realize circular firing by assembling the parts and the gun body separately. At the same time, both hands are required to cooperate with the firing. The operation process is cumbersome and requires the cooperation of assistants to fix them.
