Description

Artificial urethral sphincter

Technical Field

The invention relates to the technical field of implants, in particular to an artificial urethral sphincter used for treating male and female severe urinary incontinence.

Background

Stress urinary incontinence SUI is defined as urination of less than 50ml due to relaxation of the urethral ligaments, bulbourethral muscles, perineal muscles, and anal sphincter muscles when performing a tensile activity that suddenly increases the abdominal pressure. The stressful activities may include activities such as coughing, sneezing, laughing, lifting weight, running, blowing the nose, strenuous exercise, anxious, excited, stair climbing, sudden rising, and the like.

Stress urinary incontinence occurs primarily after female production and after male prostatectomy, and the artificial urinary sphincter AUS is currently considered the gold standard for treating stress urinary incontinence after male prostatectomy.

At present, the artificial urethral sphincter adopts a three-piece set of artificial urethral sphincter, namely, a structure formed by connecting a urethral cuff, a scrotum pump and a liquid storage bag in an abdominal cavity by using a catheter.

Detailed Description

In order to more clearly illustrate the embodiments or technical solutions in the prior art of the present invention, the drawings and technical solutions required to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

From the function of urethra sphincter oneself, imitate its control principle, when its pressure that produces through the urine of storing in the bladder reaches certain numerical value, under signal control, reach the purpose of getting rid of the urine through the motion of sphincter, but when sphincter strength is not enough, mainly take place in obesity crowd, postpartum crowd and prostate postoperative, old person's crowd. The mix of moderate to severe stress incontinence is the use of implanted artificial sphincters.

The artificial urethral sphincter muscle 2 is used by both men and women and is implanted in the urethra preferably at a location near the exit of the bladder 1, as shown in figure 1.

The first embodiment is as follows: the artificial urethral sphincter 2 comprises a plugging body 3, a plugging part A4 and a plugging part B5; the blocking body wraps the blocking part B5, the blocking body 3 is made of medical silica gel materials, the main function of the blocking body 3 is convenient for fixing an implant, the blocking body is not an indispensable component, the outer surface of the blocking body 3 is fixed on the inner surface of a urethra, the blocking part A4 penetrates through the inner surface of the blocking body 3 and is fixedly connected to the blocking part B5, the blocking part A4 is a single valve made of high polymer soft materials, the medical silica gel materials are selected, the blocking part A is opened when the pressure of liquid medicine in a bladder exceeds a pressure preset value and is closed when the pressure is below the pressure preset value, and the blocking part B5 is of an integrated supporting structure and has certain supporting strength.
