Description

Anal fistula seton device
Technical Field
The utility model relates to the technical field related to medical facilities, in particular to an anal fistula seton device.
Background
The method is commonly used in anorectal surgery for a 'thread-hanging therapy', and is commonly used in the surgical treatment of diseases such as anal fistula, perianal abscess and the like. The principle is as follows: generally, a rubber ring at the outer opening edge of a sterile rubber glove is mostly adopted as a thread hanging material for hanging threads between the inner opening and the outer opening of the anal fistula or between the inner opening and the outer opening of perianal abscess.
The operation method comprises the following steps: the inner opening is detected by a probe, the rubber ring is guided to penetrate, the outer wound is trimmed to reach an ideal state, the penetrated rubber ring is tightened and ligated, the tissue at the thread hanging part is gradually subjected to ischemic necrosis under the mechanical compression effect, the tissue of the outer tube wall, the muscle and the like is slowly cut, the anus contracting function is protected, and the effects of reducing the anal incontinence and bleeding and the like are achieved. However, in the actual operation process, the tension of the rubber ring is not easy to control, the ligature line is prone to slipping, and the like, and in the later stage of the thread hanging, because part of the ligature tissue is cut off, the tissue at the ligation part becomes thin, the relative tension of the rubber ring is reduced, the tissue cutting force cannot be achieved, and therefore the rubber ring needs to be tightened again. When the rubber ring is tightened again, local anesthetic is generally injected again before operation so as to relieve the anal pendant expansion and pain discomfort of the patient, and great fear and pain are brought to the patient.
