Description

Rotary cutting elastic line mechanism for anorectal ligation device Technical Field The utility model belongs to the technical field of medical appliances, and particularly relates to a rotary cutting elastic line mechanism for an anorectal ligature 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. In the process of performing ligation by using the ligature device, after the elastic thread is sheathed on focus tissues, the elastic thread needs to be sheared off. From the solutions of various anorectal ligature devices disclosed in the prior art, most of the solutions are realized by a manual operation mode, and the operation mode is very easy to damage mucous membranes near hemorrhoids of a patient, and high requirements are put on experience and operation proficiency of operators due to high operation difficulty. Sometimes, two people are required to cooperate at the same time to complete the operation. Therefore, there is a need for an improvement over existing solutions for anorectal ligature devices to reduce the difficulty of cutting the elastic wire during the ligature procedure. Disclosure of utility model The utility model aims to provide a rotary cutting elastic line mechanism for an anorectal ligature device, which aims to solve the problems in the background technology. In order to achieve the technical purpose, the technical scheme of the utility model comprises the following steps: A rotary-cut elastic thread mechanism for an anorectal ligation device comprises a connecting pipe, wherein one end of the connecting pipe is connected with a ligation head, a threading hole is formed in the ligation head, and one end of the threading hole is opened in the connecting pipe; The connecting pipe is internally provided with a rotating piece in a rotating way, one end of the rotating piece, which is close to the ligation head, is connected with a cutter for cutting off the elastic line, the other end of the rotating piece is connected with a driving assembly, and the threading hole corresponds to the cutter.
