Abstract
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...
