Flexible intestinal anastomosis stent

Abstract

A flexible intestinal anastomosis stent which sucks secretions on an inner wall of an intestinal tract and at a suture site into a horn-shaped channel through a through-hole. The secretion is discharged to an inside of the stent body through a liquid-inlet hole after being squeezed by intestinal tract contents, thereby reducing a risk of infection at the suture site. A lower edge of the outlet end of the stent body has a concave polygonal structure, each reflex angle at a lower edge of the concave polygonal structure being formed with one inwardly folded wrinkle structure on a side wall of the stent body, and the wrinkle structure also able to accommodate the secretions. The lower edge is stressed and deformed by the intestinal tract contents to reduce a reflex angle, so that secretions in the wrinkle structure are discharged downwardly, such that risk of complications is reduced.
