Three-ring bionic artificial anal sphincter protective sleeve for preventing tissues from proliferating inwards

Abstract

The invention relates to a three-ring bionic artificial anal sphincter protective sleeve for preventing tissues from proliferating inwards. The three-ring bionic artificial anal sphincter protective sleeve comprises an outer shell matched with a three-ring bionic artificial anus, two silica gel films and an elastic rope, wherein one sides of the two silica gel films are connected through the elastic rope, and the other sides of the two silica gel films are respectively attached to the inner sides of an upper ring and a lower ring of the three-ring bionic artificial anus through pressing sheets. The three-ring bionic anal sphincter protective sleeve is simple in overall structure, small in size, light in weight and good in sealing performance, the contact surface between an external intestinal tract and the inner part of the three-ring bionic anal sphincter prosthesis can be effectively reduced, and the problems that external tissue is proliferated and wrapped inwards, and intestinal obstruction is caused when the intestinal tract falls into the prosthesis through two ends of a port are solved; and a relatively independent closed space is formed in the prosthesis, the phenomenon that a middle ring swing arm cannot reach a specified clamping position due to tissue proliferation and intestinal obstruction is relieved, and the service life of the prosthesis is prolonged.

Description

technical field [0001] The invention relates to a technology in the field of medical devices, in particular to a three-ring bionic artificial anal sphincter protective cover for preventing tissue inward growth. Background technique [0002] The existing three-ring bionic artificial anal sphincter system designed to imitate the puborectalis can replace the external anal sphincter of patients with fecal incontinence to achieve normal physiological functions, and reshape the rectal sensation through pressure sensors and control systems to achieve autonomous bowel control. However, most of the existing sphincter prostheses are sealed shells with open structures at both ends, which are prone to tissue inward hyperplasia or intestinal obstruction during use, resulting in the failure of the artificial anal sphincter system designed to imitate the puborectalis muscle.
