AI Technical Summary

Technical Problem

Existing training models for vaginal closure are rudimentary, unable to accurately reproduce the surgical procedure, lack integration with the structure of human pelvic organs, and cannot effectively train the separation and suturing of the vaginal bladder/rectum space, posing a risk of damage to the bladder or rectum.

Method used

A training device was designed that includes a female pelvic model, a vaginal closure surgery model, and a simulated abdominal wall model. The device includes bladder and rectal models, which are fixed by Velcro or glue to simulate the real situation of vaginal closure surgery. It is divided into two models: one with a uterus and one without a uterus, to simulate different degrees of prolapse. The device uses 3D printing and flexible silicone material to simulate the multi-layered structure of the vaginal wall.

Benefits of technology

It enables realistic simulation training of vaginal closure surgery, reduces the risks in surgical procedures, improves training effectiveness and safety, reduces model maintenance costs, and facilitates cleaning and replacement.

Abstract

The invention discloses a vaginal closure training model which comprises a female pelvic cavity model, a vaginal closure model and a simulated abdominal wall model. A pelvic cavity is arranged in the female pelvic cavity model, a bladder model and a rectum model are arranged in the pelvic cavity, a simulation abdominal wall model is detachably arranged on the female pelvic cavity model through a bonding device, and a vaginal closure operation model is detachably arranged in the female pelvic cavity model. The upper end and the lower end of the vaginal closure model are respectively connected with the bladder model and the rectum model, and the vaginal closure model is divided into a uterus vaginal closure model or a non-uterus vaginal closure model; the two vagina closing models are arranged to be four-degree prolapse. After training, the training model does not need to be integrally replaced, a trainer on the same model only needs to replace the uterus and vagina closed model or the uterus and vagina closed model to obtain real simulation training of two operation modes, the cost is low, and disassembly and assembly are convenient.
