Abstract

A contact-type artificial anal sphincter prosthesis limit protection switch device, comprising: a motor casing, a transmission mechanism arranged in the motor casing, a swing arm mechanism, a limit mechanism and a controller, wherein: the swing arm mechanism and the transmission mechanism Connected, the limit mechanism includes: two limit switches connected to the controller respectively arranged on the swing arm mechanism and the motor casing, the first limit switch and the second limit switch are both switch round buttons and connected in series A limit switch circuit composed of a 10K resistor, the limit switch circuit leads to a high-level wire, a signal wire and a ground wire. In the present invention, by setting the limit switch, the switch round button can be pressed at the limit position where the swing arm of the lower ring swings to the left and right, respectively, to trigger the limit signal, and the limit signal generated by the limit switch will be transmitted to the controller for further processing. processing, simple structure, easy to realize, and high stability.

Description

technical field [0001] The invention relates to a technology in the field of medical devices, in particular to a contact-type artificial anal sphincter prosthesis limit protection switch device. Background technique [0002] The artificial anal sphincter system is an implantable device for the treatment of FI. It controls the leakage of excrement through the clamping or traction of the rectum by the mechanism, simulates the physiological function of the normal external anal sphincter, and realizes bowel control and defecation. Most of the existing position-limiting and protective anal sphincter prostheses use the principle of the Hall effect to limit the position. The effect is easily interfered by the electromagnetic effect generated by the components in the motor sleeve, and the installation process is relatively complicated and the stability is low. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention prop...
