Sealing housing protected anal sphincter prosthesis

Abstract

The invention discloses a sealing housing protected anal sphincter prosthesis, and belongs to the technical field of medical apparatuses. The sealing housing protected anal sphincter prosthesis comprises a coil box, a prosthesis clamping mechanism as well as a left sealing housing and a right sealing housing, wherein the prosthesis clamping mechanism is sequentially provided with an upper fixing ring, an arc-shaped swinging leg and a lower fixing ring in an axial direction, and the left sealing housing and the right sealing housing cover two sides of the prosthesis clamping mechanism and are fixedly connected; at the outer side of an annular structure, a driving device is encapsulated on the prosthesis clamping mechanism in an axial direction; the arc-shaped swinging leg is connected to the driving device; an electric wire passing drum is arranged at the bottom of the driving device; and the electric wire passing drum runs through the right sealing housing and is in sealed connection to the coil box by virtue of a silicone tube. According to the sealing housing protected anal sphincter prosthesis provided by the invention, by arranging the sealing housings at the outer side of the clamping mechanism, a contact area of the prosthesis and biological tissues is greatly diminished and smoothness of the outer surface of the mechanism (the prosthesis) is improved, so that mechanism failure, due to tissue exclusive hyperplasia and adhesion after implantation of the mechanism, is prevented.

Description

technical field [0001] The invention relates to a technology in the field of medical devices, in particular to a sealed shell-protected anal sphincter prosthesis. Background technique [0002] The artificial anal sphincter prosthesis simulates the physiological function of the normal external anal sphincter, senses the rectal pressure through the pressure sensor, and combines with the control system to reshape the rectal sensation and realize autonomous control of defecation, thereby treating fecal incontinence. Contents of the invention [0003] The present invention aims at making the pressure sensor used in the existing prosthesis difficult, the yield is low, it is easy to break when the prosthesis is assembled, the overall sealing performance of the prosthesis mechanism is difficult to meet the requirements, and the mechanical structure is not easy to disassemble. In view of the defects such as disassembly and assembly, a sealed shell-protected anal sphincter prosthesi...

[0003] The present invention aims at making the pressure sensor used in the existing prosthesis difficult, the yield is low, it is easy to break when the prosthesis is assembled, the overall sealing performance of the prosthesis mechanism is difficult to meet the requirements, and the mechanical structure is not easy to disassemble. In order to avoid defects such as disassembly and assembly, a sealed shell-protected anal sphincter prosthesis is proposed, which can realize the closure of the outer contour of the anal sphincter prosthesis, and avoid the problems of mechanism failure and easy displacement due to tissue rejection hyperplasia after implantation
