Abstract
The utility model discloses a twinset expandable artificial sphincter for treating severe uroclepsia. The utility model comprises an expandable urethra cuff and a scrotum pump with fluid storage room, which are connected by a duct. The urethra cuff is applied as a permeation cavity around the rear part of the penis scrotum ball cavernous body. The length can be chosen freely to be fixed by a button. The scrotum pump is provided with a unidirectional valve which pumps the fluid in the fluid storage bag into the cuff which is then expended to press the urethra to stop the flow of urine. When micturating, touch the unidirectional switch of the scrotum pump to back flow the fluid in the cuff into the fluid storage room to relieve urethra pressure so as to control the micturition freely. The utility model eliminates the caused injury and the complex of the operation due to the position of water bag in the abdominal cavity. The utility model improves the safety of he operation and reduces the odds of the Colleagues.
Description
Technical field
This utility model relates to a kind of two-piece-dress expansiveness artificial urethral sphincter, is used for the treatment of the severe urinary incontinence.
Background technology
Male's urethra is positioned at the cavernous body of penis below, originates in the intravesical external sphincter, through prostatic part, the membranous part of urethra and bulb of urethra cavernous part, is opened on the glans penis urethral orifice.Bladder has the storage urine and gets rid of the function of urine, is subjected to neural adjusting.The process of urinating is under neural adjusting, the intravesical external sphincter is lax, and detrusor of bladder shrinks and the intravesical pressure increase, gets rid of external by urethral orifice urine, be under maincenter and the adjusting of spinal nerves system, the inside and outside sphincteral coordination exercise of detrusor of bladder and urethra is finished.If peripheral nerve injury that the damage of spinal micturition center, spinal cord are sent or pathological changes and detrusor of bladder or inside and outside sphincteral 26S Proteasome Structure and Function change, the sphincter vesicae dysfunction causes that urinary dysfunction is called urinary incontinence clinically.Urinary incontinence is clinical common frdquently encountered disease, although some pharmacotherapys and operative therapy have certain curative effect to light moderate urinary incontinence,, rely on and use diaper or condom urethral catheterization year in year out the normal unsatisfactory curative effect of severe urine incontinence, cause urinary tract infection easily, have a strong impact on quality of life.At present there is the three-piece artificial urethral sphincter that the treatment of severe urinary incontinence has been obtained effect preferably abroad.Three-piece artificial urethral sphincter per urethram cuff, scrotum pump and intraperitoneal reservoir utilizes conduit to connect to form, this device is because parts cause the operation difficulty more, particularly laying the abdominal cavity pump causes tissue injury seriously to cause the surgical injury complication easily, increase operative complications, easily take place to infect and the mechanicalness complication, and cost an arm and a leg, clinical use significantly is restricted, and present most patients can not get treatment.
The present utility model person after years of research and found that, existing external three-piece sphincter of urethra since parts how particularly water pocket need be placed in intraperitoneal, operation is complicated, the many mechanicalness faults that easily take place of parts, the actual clinical that costs an arm and a leg is used and is restricted.In order to overcome the not enough point of these existing three-piece artificial sphincters, the inventor finds after deliberation, newly-designed two-piece-dress expansiveness artificial urethral sphincter, the two-piece-dress artificial urethral sphincter who comprises the hydraulic pump of band reservoir in urethra cuff and the scrotum, operation is laid simple, reduce complication, can arbitrarily control safely and effectively and urinate and treat urinary incontinence.
Summary of the invention
The purpose of this utility model provides the inflatable artificial urethral sphincter of a kind of novel two-piece-dress.This utility model provides a kind of two-piece-dress inflatable artificial urethral sphincter, the urinary incontinence that is used for the treatment of Men's and Women's, it is characterized in that: the inflatable urethra cuff that comprises a hollow, it is around the urethra setting, with a hydraulic pump that comprises check valve and switch, the urethra cuff links to each other with hydraulic pump by conduit; Liquid enters the urethra cuff by conduit during the extruding pressurized capsule, and urethra is stopped up, and push switch makes liquid return, urethral opening.
Summary of drawings
Fig. 1 is this utility model two-piece-dress expansiveness artificial urethral sphincter's a profile
Fig. 2 (a) and (b) be this utility model two-piece-dress expansiveness artificial urethral sphincter's functional schematic
Best mode for carrying out the invention
Below by embodiment and with reference to accompanying drawing this utility model is described.Identical in the accompanying drawings parts are represented with same label.
The functional schematic that has shown the inflatable artificial urethral sphincter of two-piece-dress of the present utility model among Fig. 2, wherein, label 9 is depicted as bladder, and label 10 is depicted as urethra.The artificial urethral sphincter comprises the inflatable urethra cuff 1 of a hollow, and it can charge into certain amount of fluid by for example manufacturing such as silicone rubber or polyethylene of expandable medical material, makes it full.Described urethra cuff 1 is embedding around urethra 10, as shown in fig. 1.Fixedly button 3 of two rows is arranged on the urethra cuff 1, can regulate according to the thickness of urethra, as shown in fig. 1.Urethra cuff 1 width range is 0.5-5.0cm, and length range is 5.0-10.0cm.
The artificial urethral sphincter also comprises the hydraulic pump 11 of planting in scrotum (women can plant in below labium majus), and it comprises reservoir 4 and pressurized capsule 5, wherein can store certain amount of fluid respectively.And comprising check valve 6,7, check valve is used for the flow direction of controlling liquid.Check valve can be established one or two.The hydraulic pump shape can be circle, ellipse or square, and width is 1-5cm, highly is 1-5cm, and thickness is 1-5cm, also comprises switch 8.Urethra cuff 1 links to each other with hydraulic pump 11 by conduit 2.
The inflatable artificial urethral sphincter's of two-piece-dress of the present utility model work is described below with reference to Fig. 2.
Shown in Fig. 2 (b), when extruding pressurized capsule 5, make the liquid in the reservoir 4 enter urethra cuff 1 by conduit 2, the full expansion of liquid stopped up urethra in the urethra cuff 1, and the patient can not urinate.But the switch 8 of applying light hydraulic pump 11 during controlled micturition makes urethra cuff 1 interior liquid return go into reservoir 4, and urethral opening is discharged urine, shown in Fig. 2 (a).
Medical application
Two-piece-dress expansiveness artificial urethral sphincter's step is implanted in operation:
Corrective surgery anterior perineum portion is thoroughly cleaned, and perineal position utilizes iodine fluorine sterilization 15 minutes under the spinal anesthesia, executes cystostomy, and urethra is placed catheter.The place makes 3cm stringer skin incision in ventral of penis penis and scrotum skin interface, cuts shallow deep fascia successively, separates the long 3cm of back cavernous body of urethra.Lay the urethra cuff, button is fixed behind the adjustment suitable length, and the scrotum pump fills normal saline, peels off the space under the scrotal wall fascia, lays scrotum pump (women can be placed in the labium majus below), connecting duct.It is full that the urethra cuff is brought out in scrotum pump pressurization, removes catheter, by pinching the switch experiment of urinating, guarantees that function is normal, cuts off the cuff redundance, sews up the incision successively, wraps up.Postoperative uses one week of antibiotics.Remove the bladder fistula after one month, can urinate by manually making sphincter.
