Bladder urethral nested stapler

Abstract

The invention discloses a bladder urethral nested stapler comprising an inner sleeve (1), an outer sleeve (2) and a fixing belt (5). The inner sleeve comprises a bladder connecting portion (11), a sleeve connecting portion (12) and a sleeve portion (13). The bladder connecting portion is a spherical structure, the sleeve portion tensions a bladder outlet, and the sleeve connecting portion is formed by a plurality of connecting claws with barbs (121); the outer sleeve is provided with a circle of annular burrs (22), and the outer sleeve contacts the inner wall of the urethra by burrs and is fixed by a fixing strap. The outer sleeve is provided with a sleeve insertion hole (21), and the barbs are matched with the sleeve insertion hole. The outer sleeve is fixed in the outer sleeve in the sleeve mode. A urethra proximal urethral outer membrane and a bladder outlet outer membrane contact in a cavity between the inner side of the spherical structure of the bladder connecting portion and theouter side on the upper portion of the sleeve portion, and the inner sleeve and the outer sleeve are communicated with the bladder and the urethra. The stapler can make the urethra and the bladder achieve anastomosis, and improve the operation efficiency. A patient can recover quickly after operation, and the problems of anastomotic stricture and urinary fistula can be solved.

Description

technical field [0001] The invention relates to a urological surgical instrument, in particular to a bladder urethra sleeve-inserted stapler. Background technique [0002] With the accelerated pace of life and changes in living habits, the incidence of cancer in modern people is increasing year by year, among which prostate cancer is the most common malignant tumor in the male urinary system. At present, the main method of treating prostate cancer is prostatectomy, and the key to prostatectomy is the anastomosis of bladder and urethra after operation. The anastomosis of bladder and urethra may directly affect the patient's recovery and life. [0003] In traditional prostatectomy, the bladder and urethra are anastomosed mostly by stump suturing. Due to the difficulty of suturing and the narrow space for suturing, the anastomosis is often narrowed, and poor anastomosis may also cause complications such as urinary fistula. Postoperative recovery is slow, and during the recover...

AI Technical Summary

Problems solved by technology

[0003] In traditional prostatectomy, the bladder and urethra are anastomosed mostly by stump suturing. Due to the difficulty of suturing and the narrow space for suturing, the anastomosis is often narrowed, and poor anastomosis may also cause complications such as urinary fistula. Postoperative recovery is slow, and during the recovery period (at least 2 weeks), catheterization is required, which brings great pain to the patient and great inconvenience to the life of the patient

Currently, there is no stapler for the closure of the urethra and bladder during prostatectomy
