Fixator for promoting healing of urethral wounds and anastomotic stomas between urethra and bladder neck

Abstract

The invention discloses a fixator for promoting healing of urethral wounds and anastomotic stomas between a urethra and a bladder neck. The fixator comprises short trousers, a baseplate adhering to the front sides of the short trousers, elastic binding ropes which are connected between the short trousers and the baseplate, rams which are hinged to the front side of the baseplate, a catheter clamping buckle which is fixed to the front ends of the rams and a catheter which backward penetrates from the catheter clamping buckle. After operations, such as radical prostatectomy, electrovaporization of the prostate, urethral reunion operation, bladder cancer radical surgery (orthotopic neobladder) and urethral stricture operation, and when the urethra is injured to bleeding and the catheter needs to be pulled outwards, the fixator is used so that the connection between two broken ends of the urethra or the anastomotic stomas between the urethra and the bladder neck can be tighter, the wounds or the anastomotic stomas can be tighter, bleeding is reduced, and the fixator promotes healing of the wounds or the anastomotic stomas and can also be used for oppressing the urethra to stop bleeding by pulling the catheter when the urethra is injured.

Description

technical field [0001] The invention relates to a medical device, in particular to a fixer for promoting the healing of urethral wounds and the anastomosis of the urethra and bladder neck. Background technique [0002] Radical prostatectomy, radical cystectomy (in situ neobladder), transurethral transurethral resection of the prostate, transurethral enucleation of the benign prostate, urethral reunion, and urethral bleeding due to urethral injury require indwelling catheters. One is that after urethral reconstruction, the two ends are sutured. Due to the relatively small surgical space in the pelvis, the sutures may be pulled too loosely during suturing. Docking affects the healing of the anastomosis, and sometimes there is bleeding at the anastomosis, which leads to delayed healing of the anastomosis, and postoperative hematuria in patients, which increases the probability of infection and increases the psychological burden on patients. Therefore, it is necessary to exert ...

AI Technical Summary

Problems solved by technology

This kind of solution is inaccurate in hemostasis, and the operation is very inconvenient. Now it is necessary to provide a fixation device to promote the healing of urethral wound or bladder neck anastomosis. It can pull the urinary catheter outward without compressing the glans or urethral opening, and it will not affect the healthy tissue. Harmless and easy to operate
