End-to-end bulbar urethral anastomosis training model and preparation method thereof

Abstract

The invention discloses an end-to-end bulbar urethral anastomosis training model and a preparation method thereof, and relates to the field of surgical training models. The training model comprises apelvic model, a bulbar urethral stenosis model and a urethra-rectum-pelvic floor muscle group model. The pelvic model and the urethra-rectum-pelvic floor muscle group model are fixedly connected through slot ports and connectors. The urethra-rectum-pelvic floor muscle group model comprises a pelvic floor muscle group model, a rectum model and a urethral model. The urethral model is located in themiddle of the pelvic model and comprises a bladder part, a prostate part and a urethra part. The preset stenosis segment of the urethra part is provided with the bulbar urethral stenosis model which is nested into the preset stenosis segment in a nested manner. The rectum model is located at the rear end of the pelvic model. Yellow liquid is filled in the rectum model. The pelvic floor muscle group model is located at the bottom end of the pelvic model. The training model is highly matched with the actual clinical surgery and is favorable for doctors to quickly grasp the practical surgical skills of the urethral stenosis.

Description

Technical field [0001] The invention relates to the field of surgical training models, in particular to a surgical training model for bulbous urethral end-to-end anastomosis and a preparation method thereof. Background technique [0002] Urethral stricture is one of the more common and difficult-to-treat diseases in urology. Its incidence rate is 300-600 / 100,000, and it has been increasing in China in the past decade. However, urethral repair and reconstruction is often difficult in clinical practice due to its difficult operation, high technical requirements, low success rate, and many postoperative complications. [0003] The male urethra extends from the urethral opening at the bladder neck to the outer urethral opening, about 16-22 cm long. The average pipe diameter is 5-7mm. It can be divided into cavernous body, bulb, membrane and prostate. The bulbous urethra is the enlarged part of the posterior end of the corpus cavernosum. It is located between the feet of the penis on...

Problems solved by technology

The crux of the problem is that the previous preparation techniques cannot simulate the specific lesions of urethral stricture and surrounding cavernous body fibrosis
