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.
