Self-assembled replaceable modular simulated trainer for end-to-end anastomosis simulated surgery for human urethra

Abstract

The invention relates to a self-assembled replaceable modular simulated trainer for an end-to-end anastomosis simulated surgery for human urethra. The self-assembled replaceable modular simulated trainer comprises a trainer main body, a urinary bladder module, a prostate module and a replaceable urethra end-to-end anastomosis module; the replaceable urethra end-to-end anastomosis module comprisesa penis and scrotum surface part, a urethra catheter, a muscular tissue part and a funnel-like connector; the penis and scrotum surface part comprises a scrotum, a penis and peripheral epidermal tissues of the scrotum and the penis; the penis and scrotum surface part is connected with the muscular tissue part; the urethra catheter is in communication with the funnel-like connector by penetrating the penis into the muscular tissue part and is furthermore connected with a urinary bladder; the urethra catheter is internally provided with a solid cylindrical module; a through hole I concavely andconvexly matched with the muscular tissue part is formed in a perineum region of the hollow trainer main body; and the hollow urinary bladder module opened at two ends and the prostate module are located in the trainer main body. The simulated trainer disclosed by the invention is high in simulation degree, vivid in experience, capable of improving the surgery skill of medical workers and conveniently replacing damaged parts and low in cost.

Description

technical field [0001] The invention belongs to the technical field of medical teaching moulds, and relates to a self-assembled replaceable modular human urethral end-to-end anastomosis simulation operation simulation trainer, in particular to a surgical simulation trainer for urethral repair and reconstruction surgery. Background technique [0002] Urethral stricture is a relatively common and difficult disease in urology, with an incidence rate of 3-6 million per 100,000 patients. The incidence rate in China has shown a trend of continuous increase in the past ten years. However, urethral repair and reconstruction are often difficult to deal with in clinical practice due to the characteristics of difficult operation, high technical requirements, low success rate and many postoperative complications. [0003] The male urethra is from the urethral opening of the bladder neck to the external opening of the urethra. It is about 16-22 cm long and has an average diameter of 5-7 ...

AI Technical Summary

Problems solved by technology

However, there are obvious regional differences in the diagnosis and treatment of urinary tract diseases in China at present. Because the grassroots hospitals do not admit a corresponding number of patients, urological surgeons perform urethral repair and reconstruction operations, especially the end-to-end anastomosis of urethra. Not getting enough exercise, resulting in unsatisfactory clinical efficacy

Although the specialized tertiary hospitals can absorb a large number of patients with urinary tract diseases every year, they monopolize the technology in the industry, and only a small number of doctors in surrounding hospitals can get clinical guidance, which limits the widespread popularization of this type of technology
