Abstract

This invention discloses an auxiliary device and method for anorectal surgery, belonging to the field of medical device technology. The anorectal surgery auxiliary device includes an outer cylinder and an inner cylinder, with the outer cylinder sleeved over the inner cylinder and rotatably connected to it. The inner cylinder includes a rotating cylinder with an operating window on its upper side wall. A sealing plate is installed inside the rotating cylinder to block the operating window. A moving mechanism is installed inside the rotating cylinder to move the sealing plate within the inner cylinder. A locking structure is installed on the side wall of the rotating cylinder to lock the rotating cylinder to the outer cylinder. The locking structure is connected to the moving mechanism, and the moving mechanism drives the locking structure to move synchronously, so that when the operating window is opened, the locking structure locks the rotating cylinder to the outer cylinder. Using the anorectal surgery auxiliary device and method described in this invention solves the problems of existing auxiliary devices being inconvenient to use and prone to causing damage to the affected area.
