Disposable automatic anorectal loop ligation gun

Abstract

The invention belongs to the technical field of medical auxiliary instruments and equipment, and particularly relates to a disposable automatic anorectal loop ligation gun. The disposable automatic anorectal loop ligation gun comprises a gun shell provided with a gun barrel and a grip, and further comprises an adsorption assembly arranged in the gun shell; the adsorption assembly comprises an adsorption pipe arranged in the gun shell, a first spring arranged at the rear end of the adsorption pipe in a sleeving mode, a push rod arranged on the rear side of the adsorption pipe, a switch piece arranged on the lower side of the push rod, a second spring arranged on a guide shaft in a sleeving mode and a third spring arranged between the push rod and the gun shell. According to the disposable automatic anorectal loop ligature gun, in the whole loop ligature process, only the adsorption pipe and the push rod slightly slide forwards and backwards, the switch piece slightly slides leftwards and rightwards, the relative movement amount in the whole process is small, the stroke is short, the operation force is small, convenience and labor saving are achieved in the operation process, the stress of a structural piece is small, thus the structure is more stable, the requirements of processing and production on material strength and the like and the process requirements during processing are low, and the production cost is low.

Description

technical field [0001] The application belongs to the technical field of medical auxiliary equipment, in particular to a disposable automatic anorectal ligation gun. Background technique [0002] Anorectal ligation device is a commonly used medical device for anorectal ligation operation, which can reduce medical operation time, operation difficulty and operation cost. With the upgrading of equipment and material technology, people have developed many types of ligation devices. Among them, manual control ligation devices are low in cost, high in safety, and easy to use, and are welcomed by medical institutions at all levels. There are many ligation devices that use various mechanical drives and work, but due to the limitation of cost and material properties, the current manual ligation equipment either relies on manpower to drive the main process, which is flexible but slow and inefficient, or Use spring mechanism and small electronic equipment to complete the adsorption co...

Problems solved by technology

With the upgrading of equipment and material technology, people have developed many types of ligation devices. Among them, manual control ligation devices are low in cost, high in safety, and easy to use, and are welcomed by medical institutions at all levels. There are many ligation devices that use various mechanical drives and work, but due to the limitation of cost and material properties, the current manual ligation equipment either relies on manpower to drive the main process, which is flexible but slow and inefficient, or Use spring mechanism and small electronic equipment to complete the adsorption control. Although the speed is fast, the structure is complex and the cost is high. At the same time, the internal structure is relatively complicated relative to the movement process, and the control is relatively troublesome. It is easy to cause operation due to inaccurate alignment and other reasons. Failure, various reasons, lead to the fact that most of the current ligation tools have not been widely promoted and applied in various primary medical structures
