Manufacturing method of rectal cancer operation training model and rectal cancer operation training model

Abstract

The invention provides a rectal cancer operation training model manufacturing method and a rectal cancer operation training model, and relates to the technical field of medical treatment. According to the manufacturing method of the rectal cancer operation training model, the stomach tissue is made into a barrel shape, one end simulates the anus end, the mucosa layer at the other end is connected with the rectum module to simulate the rectum of the human body, the serosal layer is fixed to the peritoneum, the serosal layer and the mucosa layer form the presacral space, and the stomach tissue is of a double-layer membrane structure and is close to the rectum in texture; the preparation method disclosed by the invention is simple and quick, the materials are convenient to take, and the cost is low. The rectal cancer surgery training model provided by the invention is manufactured by taking in-vitro stomach tissue, rectal tissue and peritoneum as raw materials, fully simulates the human rectal environment, can be used for training rectal cancer surgery, ensures feedback of training operation touch and strength, enables doctors to obtain real and convenient skill training, and improves surgical skills; meanwhile, the training environment is simplified, and investment of sites and labor is saved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for making a rectal cancer surgery training model and a rectal cancer surgery training model. Background technique [0002] In a historical period, surgeons mostly used the teaching mode of training skills on patients, but at the same time brought huge risks in practicing medicine; in order to avoid such risks and master surgical skills, various non-human skill training emerged as the times require . [0003] The current surgical training doctors can only use single animal organs purchased from the market for training, or use live animal surgery, and use virtual simulators composed of 3D animation and force feedback systems, and use plastic, silicone and other products as training modules A simple simulation box for . [0004] However, 1) The organs harvested by ordinary methods are independent of each other, such as a single heart, lung, and trachea, and there is no ...

AI Technical Summary

Problems solved by technology

[0004] However, 1) The organs harvested by ordinary methods are independent of each other, such as a single heart, lung, and trachea, and there is no vascular access, so it is impossible to practice techniques such as separation between organs, naked blood vessels, and hemostasis; it cannot be effectively used for surgical simulation train

[0005] 2) Animal surgery using live animals requires supporting conditions such as animal operating room, temporary animal breeding room, and anesthesia equipment. The investment in venues, personnel, and equipment is high, and the convenience is small, which makes the training cost very high. It is difficult for ordinary doctors to have the opportunity to practice a lot To meet the skill requirements of actual human surgery

[0006] 3) Existing surgical training equipment that does not use animal organs. First, a simple box-type simulator can only train basic abilities such as spatial sense conversion, hand-eye coordination, and hand-hand coordination. The skill coverage is small and cannot meet the needs of human surgical operations ( Such as the use of energy equipment and surgical procedures, etc.)

[0007] 4) The second type of surgical training equipment that does not use animal organs is a 3D simulator, but human tissue is a complex multi-layer material, and because its properties depend on the number of layers, thickness of layers, orientation of muscle fibers, humidity, temperature Wait, it's hard to simulate in 3D
