Anal canal expansion device for anorectal surgery

Abstract

The invention discloses an anal canal expansion device for anorectal surgery, which comprises a jacking column mechanism, an anal canal expansion device, a lifting column mechanism, an anal canal expansion device, a lifting column mechanism and an anal canal expansion device, and is characterized in that the jacking column mechanism extends into the anal canal and expands the anal canal; the pumping mechanism is used for driving the jacking column mechanism to intermittently, gradually and equidistantly extend into the anal canal; the guide piece is used for guiding the movement of the jacking column mechanism; the pumping mechanism and the guide part are both mounted on the mounting frame; the jacking column mechanism is fixed with the pumping mechanism through a connecting piece; due to the fact that the outer diameter of the central column is small, the anal tube can be pre-expanded, and a patient has a certain adaptation time; then a first motor is controlled to rotate slowly through an external controller, the first motor drives a supporting rod to gradually expand outwards, and the supporting rod gradually makes contact with the anal canal inner membrane and drives the anal canal inner membrane to do small-amplitude movement; the expansion amplitude of the anal canal inner membrane by the supporting rod is controlled by controlling the rotating speed of the first motor, and compared with manual fingers, the operation is more stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of anorectal surgical instruments, and relates to an anal canal expansion device for anorectal surgery. Background technique [0002] Anus expansion is also called anal canal expansion. Anus expansion is often used for anorectal disease inspection, treatment and postoperative recovery. The expansion of the anus before the operation can make the anus fully relax, and the surgical field of vision is clear, which is convenient for the doctor to operate. [0003] Existing anus dilation is mostly artificial finger dilation, and the doctor needs the patient to gradually adapt to the patient's anus expansion, which undoubtedly increases the doctor's labor intensity; The operation of time, it is difficult to achieve the purpose of rapid expansion of the anus; and rapid expansion of the anus is likely to cause laceration of the mucosa and anal canal, which not only easily causes secondary damage to the patient, but ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem in the background technology that when the doctor expands the anus with the artificial fingers of the patient, it not only increases the labor intensity of the doctor, but also easily causes secondary injury to the patient when the doctor operates the anus rapidly, the present invention proposes an anal canal for anorectal surgery.
