Abstract

The utility model belongs to the technical field of medical equipment, and particularly relates to a pressure release switch for an anorectal ligation device, which comprises an adapter, wherein the adapter is fixedly arranged on the inner side wall of a shell of the anorectal ligation device, the adapter comprises a main air pipeline and a branch air pipeline communicated with the main air pipeline, one end of the main air pipeline is communicated with a negative pressure device, the other end of the main air pipeline is communicated with an air circuit component contacted with focus tissues, and a sealing plug is arranged at the pipe orifice of the branch air pipeline and is driven to move by a driving mechanism. By arranging the sealing plug at the pipe orifice of the bronchus of the adapter, after the driving mechanism drives the sealing plug to be separated from the pipe orifice of the bronchus, gas enters from the pipe orifice of the bronchus so as to eliminate negative pressure in the first cavity. The negative pressure switch is integrated to the hand-held part of the anorectal ligation device, can be operated by one hand, is flexible to use, and avoids the reciprocating movement of an operator between the negative pressure device and the operating platform.

Description

Pressure release switch for anorectal ligation device Technical Field The utility model belongs to the technical field of medical instruments, and particularly relates to a pressure release switch for an anorectal ligation device. Background Anorectal ligature device is an important medical instrument for treating diseases such as hemorrhoids and the like. The main working principle of the anorectal ligation device is that a tight annular ligation is formed on pathological tissues through a ligation head so as to block blood flow of the pathological tissues, so that the pathological tissues are necrotized and finally fall off. The utility model has the advantages of simple operation and low complication probability. When the ligation device is used for ligating focus tissues, the focus tissues are sucked into a specific cavity by negative pressure, and then a series of operations such as ligating elastic lines at the root of the focus tissues and cutting the elastic lines are performed. When this is done, it is necessary to return the cavity to normal pressure in order to separate the lesion tissue from the cavity. By retrieving the technical scheme disclosed in the prior art, most ligature devices generate negative pressure through an external negative pressure device, and the generation and release of the negative pressure are controlled through a start-stop switch on the negative pressure device. This results in the operator moving back and forth between the console and the negative pressure device to control the start and stop of the negative pressure device, which is inconvenient to operate. Accordingly, there is a need for improvements over the prior art. Disclosure of utility model The utility model aims to provide a pressure release switch for anorectal ligation, which aims to solve the problems in the background technology.
