Background
Some patients suffer from urethral sphincter injury or dysfunction due to physiological dysfunction, accidents, diseases, or surgery. In this obstacle, the patient may be faced with the problem of uncontrolled urination. Some patients can gradually recover from the normal state by recovering the function of the urethral sphincter through continuous muscle exercise; however, some patients are also constantly exposed to urinary incontinence, which leads to a reduction in quality of life.
Currently, the artificial urethra is an implanted artificial organ which utilizes a special urethral cuff to wrap around the urethra and controls the inflation and the deflation of the urethral cuff by a liquid storage bag and a control pump so as to realize the normal urination function. The operation requires the placement of the cuff on the posterior urethra. When urination is needed, the control pump is squeezed to enable liquid in the sleeve to flow to the liquid storage bag, and the urethra is opened after the liquid in the sleeve is emptied; after urination is finished, liquid automatically flows into the oversleeve under the elastic retraction action of the pressure adjusting saccule until the pressure in the system is balanced, and urethral closure is realized. At present, a control pump for controlling liquid flow is operated by a manual mechanical pressing mode, however, the manual operation mode brings certain inconvenience in the actual use process, and if the manual operation mode is changed into an automatic control mode, a lot of convenience is brought.
However, changing from manual control to automatic control presents great difficulties.
