Description

Medical control device and application thereof Technical Field The invention relates to a medical control device and application thereof, and belongs to the technical field of medical appliances. Background At present, the global prostate cancer patients are over 5000 ten thousand, and even under the assistance of an operation robot, about 20% of the possibility exists in the process of prostate radical cutting operation that parasympathetic nerves controlling the urethra are damaged, the sphincter is relaxed, the urethra cannot be completely closed, enuresis is caused, and great pain is caused to the psychology of the patients. For this complication, currently, products in the field mostly adopt a cuff structure (as shown in fig. 9) surrounding the urethra, and the above cuff structure has high product failure rate and has the following problems in the use process: the circumference of the sleeve 201 surrounds the urethra, so that the blood flow of the urethra is poor, the urethra can not be rapidly opened for urination during urination, and the urethra can shrink and become thin in severe cases. The control pump 202 needs to be pressed for many times to control the urine by expanding the sleeve 201, so that the check valve in the control pump 202 is worn and easy to leak after frequent use, and the pressure of the sleeve 101 is relieved, so that the urine control cannot be realized. The pressure of the sleeve 201 pressing against the urethra needs a large liquid storage balloon 203, and the liquid storage balloon is often in an inflated state, and is easy to age and relax in a long-term inflated state because the liquid storage balloon is made of silica gel, so that the sleeve loses pressure and the urine control fails. Fourth, the reservoir 203 is relatively bulky, and the patient is more afflicted with the need to open the abdomen above the scrotum during implantation.
