TECHNICAL FIELD
[0001] The present application belongs to the technical field of medical training apparatus models, and particularly relates to a colposynchlipsis training model. BACKGROUND
[0002] Colposynchlipsis is a safe and effective surgical procedure for the treatment of severe pelvic organ prolapse, with a history of more than a hundred years. It is mainly suitable for female patients who are old, have no sexual life needs, and have many complications. Colposynchlipsis achieves reliable anatomical reduction with minimal trauma, and has irreplaceable value for patients who are old and have many complications. The postoperative prolapse symptom relief rate is greater than 90%, and the social and economic cost-effectiveness is high.
[0003] The vagina is one of the important organs in the female pelvis, and the anterior wall is connected with the urethra and bladder, and the posterior wall is connected with the rectum. Due to the similar anatomy, the bladder or rectum is easily damaged during separation. Therefore, it is an urgent problem to avoid the risks caused by surgical operation to the greatest extent. Through an effective training model, medical practitioners not only familiarize themselves with the surgical steps (vaginal bladder / rectum interstitial mucosa separation, folding and suturing, etc.), reducing errors in actual operation; and through a large amount of training and simulation operation training, the risk of bladder and / or rectal injury can be reduced, and the safety of patients can be improved.
[0004] At present, the training models for colposynchlipsis at home and abroad mainly have the following deficiencies: 1) the training model is simple and only used for simple simulation of surgical steps; 2) during the training process, the model based on the training cannot truly reproduce the real situation that may occur during colposynchlipsis, such as the need to separate the vaginal bladder interstitial space before incision of the vaginal mucosa; 3) the model is not combined with the internal pelvic organ structure of the real human body, and the vaginal prolapse model is trained separately, and important surgical operations such as vaginal bladder / rectum interstitial separation and folding and suturing of the anterior and posterior walls of the vagina cannot be trained.
