Problems solved by technology

However, the energy supply problem has always been the "bottleneck" of the above-mentioned equipment. The early in vitro streamer power supply method has been eliminated due to the high infection rate and complications after surgery. For high-power transplantation equipment, the traditional battery power supply is also short-lived due to its large size. not widely used
However, this technology does not involve the design specifications and requirements of the energy coil, and is not suitable for the wireless power of the artificial anal sphincter.

Abstract

A wireless in-vivo charging system based on percutaneous energy transmission and applied to a artificial anal sphincter prosthesis comprises a wireless energy transmitting terminal and a wireless energy receiving terminal, wherein the wireless energy transmitting terminal consists of an inverter circuit and a transmitting coil, and the wireless energy receiving terminal consists of an LC resonance circuit, a rectification filter circuit and a load circuit. The wireless in-vivo charging system is easy to miniaturize, light in mass and convenient to implant and enable a whole artificial anal sphincter system to be humanized.

Description

technical field [0001] The invention designs a device in the technical field of medical devices, specifically a wireless charging system in the body based on percutaneous energy transmission suitable for artificial anal sphincter. Background technique [0002] Fecal incontinence is a clinically common disease. According to statistics, the incidence rate of adults is as high as 2%, and the incidence rate of people over 65 years old can reach 7%. underestimated. Fecal incontinence refers to the loss of the anal sphincter's ability to control the excretion of feces and gas. It is easy to cause a variety of complications, which not only brings great pain to patients, but also brings many difficulties to nursing work. With the aging trend of the population With the development, fecal incontinence has become one of the clinical diseases that urgently need to be solved. [0003] Artificial anal sphincter is to use artificial organ-artificial anal sphincter to simulate the physiol...
