Based on the hardware of the new artificial anal sphincter system, this paper analyzes the power consumption of each module. After low-power consumption design and reasonable setting of the sampling period, the system power consumption is significantly reduced. At the same time, the area under the rectal pressure waveform is used as the standard for judging defecation willingness. Instead of the single-point pressure threshold method, it provides a basis for anal incontinence patients to go to the toilet, and thus improves the accuracy of the rectal perception function. Combining in vitro and in vivo experiments, the low-power consumption of the artificial anal sphincter designed in this paper can extend the working time of the system to 16 d after a single charge. It increases the working time by 230% with a rectal perception accuracy of 96%.
