Abstract

Disclosed is a wireless energy transmission device for an artificial anal sphincter. The wireless energy transmission device is characterized by comprising a wireless energy emission module located in vitro and a sphincter execution module located in vivo and provided with a wireless energy receiving module, wherein the wireless energy emission module comprises an inverter circuit and an energy emission coil, and the wireless energy receiving module comprises an energy receiving coil, a compensation capacitor and a rectification and filter circuit. Magnetic resistance between coils is lowered to some extent, and energy transmission efficiency is improved.

Description

technical field [0001] The invention relates to a technology in the field of medical equipment, in particular to a wireless energy transmission device for artificial anal sphincter. Background technique [0002] Anal incontinence is a common clinical disease, mainly caused by diseases such as pelvic floor dysfunction, rectal cancer, trauma, and maternal delivery. Although this disease is not fatal, it brings inconvenience and physical and mental pain to the patient. According to statistics, the incidence rate of anal incontinence among adults is as high as 2%, and it tends to be aging. Among the various fields involved in anal incontinence, most cases of anal incontinence occur after colorectal cancer surgery, and the incidence of colorectal cancer in the world is also on the rise. According to statistical literature estimates in 2012, the incidence of colorectal cancer in my country reached 172,000. Therefore, the prevalence of anal incontinence has also increased, and t...
