Description

Prostate urethreurynter in body

This utility model relates to a kind of prostate-urethra rack for the treatment of male prostatic hyperplasia disease and posterior urethral stricture and belongs to Urology Surgery technique with the apparatus field.

Along with the prolongation of human longevity, senile prostatic hypertrophy disease patient will increase thereupon.At present this sick Therapeutic Method is mainly contained: 1. Drug therapy; 2. prostatectomy; 3. prostate dilatation; 4. prostate refers to split dilation operation; 5. bladder is forever made flaccidity or long-term indwelling catheter etc.But medication effect is not good; The operative treatment wound has strict indication greatly, massive hemorrhage may occur in the operation or after the operation, and urinary incontinence, sexual impotence, urethral stricture are blocked, the epididymitis complication, patient bears heavily, and the surgical technic of surgeon is also had relatively high expectations, and the long-term effect of operation is also undesirable.

The purpose of this utility model is a kind of prostate-urethra rack of design, is used for the treatment of hyperplasia of prostate and posterior urethral stricture disease, to overcome all drawbacks in the above-mentioned Therapeutic Method.

This utility model is to realize like this.Prostate-urethra rack is the approximate ampullar support of garden cylindricality, and funnel (1) is arranged at top, and the center has a through hole (2) up and down, has plurality of side conduction hole (3) to link to each other with through hole (2) on the certain position of termination around the bottom.Support is made with silica gel or silastic material, good biocompatibility, and the life-span is long, non-invasive.

Fig. 2 installs and uses sketch map for prostate-urethra rack

Sequence number among the figure (4) is that knob portion, (5) are the prostate-urethra rack that places prostate-urethra for outgrowth prostate, (6), and (7) are the musculus sphincter of external urethra.

Adopt the utility model, determine prostate-urethra length through B ultrasonic or cysto urethrography before the art, choose suitable support. Situation in the cystoscopy bladder, what need not surgical procedure can be with support Insert from orificium urethrae externum, push in the bladder with cystoscope or urethral sound. Make knob section (4) towards the orificium urethrae internum by cystoscope adjusting pole position, withdraw from cystoscope, prior two draught lines that are through at front conduction hole (3) that intersect of tractive make support be fixed in prostate-urethra again. Postoperative urinate immediately observe normal and the cysto urethrography backing positions normal after, can pull out draught line. Show inaccurate, the paruria in position such as radiography, can pass through draught line or urethral sound adjustment. Bladder has pathology to need surgical procedure person or the per urethra can not insertion person, can on phalanx, cut bladder, process in the bladder and detect prostate-urethra length with finger after the pathology, it is suitable that support is selected, and surpasses the musculus sphincter of external urethra or too short support is invalid causes the incontinence of postoperative urethra or urinate still difficulty to avoid long. Behind the placing rack conventional bladder make impotence (the support pars infundibularis can be sewed up two pins in the art and be fixed in bladder neck) but postoperative examination folder is made the tube pulling in 2～3 days of impotence pipe unobstructed micturition.

Ankylurethria determined curative effect behind the utility model treatment hyperplasia of prostate and the operation on prostate, complication is few, be applicable to various types of hyperplasias of prostate, and operation technique is simple, the institute-level surgeon of health namely can operate through short-term cultivation, the utility model abundant raw materials, make simple, cheap, alleviated patient's financial burden, popularizing application prospect has been arranged very much.

Embodiment: this utility model can be divided into 35mm, 40mm, 45mm, 50mm, five kinds of specifications of 55mm by length.Its infundibulum length is 5mm bell mouth overall diameter 15mm, and center bore is 3mm, and ampulla shape two ends overall diameter is 7mm, and the stage casing largest outer diameter is 9mm.Length is to be provided with 6 side conduction holes around 35mm, the 40mm support leading portion 15mm place, and length is to be provided with 8 side conduction holes around 45mm, the 50mm support leading portion 18mm place.Side conduction hole overall diameter 3mm, interior diameter 1mm, upper and lower pitch-row is 4mm.
