New description: . [New technical field] This creation is a model of artificial material mucosal lesions, especially a model of artificial material mucosal lesions used to train endoscopic submucosal dissection. [Previous technique] The development of endoscopic submucosal dissection (ESD) is to provide a complete overall lesion resection for large lesions that cannot be removed by conventional endoscopic mucosal resection. Provide more detailed pathological judgment on the extent of lesion invasion, in order to achieve early digestive tract cancer, which is exempted from traditional surgery and each has its own 'oral therapy. Since 1995, two scholars, Hosokawa and Yoshida, have developed the Ting Yang (丨细(四)d ϋρ by using the needle-feet of the endoscopic nipple sphincter scabbard (needle tofe) -knife). Later, Japanese doctors G〇t〇da and 〇n〇 were first used for the removal of colorectal polyps. Now, with the development of new devices and the popularization of technology, in Japan, endoscopic and microscopic submucosal dissection has become the standard treatment for early esophageal cancer, gastric cancer and colorectal cancer. 0 σ Dioxins are still confined to the original organs and have not spread.遂us 'Right this day is Wei, the cancer cells 彳 _ clean, ~ will not have a chance to re-issue. In the assessment, the quality of the surgery can be in the state of the smallest injury to the disease, the most preserved H official function (four) state; surgery is the perfect surgery. When the early field ^ > muscle layer above, there are few lymph nodes ^ road = tumor invasion ship in the axis of rotation 喊 喊 在 在 在 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不 不Most beneficial. Therefore, endoscopic submucosal dissection (ESD) for local tumor resection can not only completely remove the tumor, but also avoid the function of the gastrointestinal tract. Endoscopic submucosal dissection is a highly endoscopic technique that involves at least the following basic steps: (1) Identifying the lesion and setting the range, making a ring-mark outside the lesion. (B) Injecting physiological saline (with a sterile stain) into the lesions to make the lesions bulge around. (3) Using a ΙΤ1]α1ί^ electrosurgical knife to perform a circular incision around the lesion to separate the lesion from the surrounding normal tissue. (4) Gradually perform submucosal dissection with an IT-knife electrosurgical knife, etc., and completely decoy the lesion and its underlying tissue. (5) Hunan hemostasis or electrocautery ^ to carry out the treatment of hemostasis and bare blood vessels, and finally the lesion was successfully stripped and measured. Endoscopic submucosal dissection must be performed under the experience of an experienced physician. The technique of the endoscope is gradual, but it is also labor-intensive and labor-intensive. In the first stage, it is necessary to observe the teaching films and the steps and concepts of the expert operation. However, endoscopic submucosal dissection requires a delicate endoscope #, these techniques are not able to learn the essence of the film. In the second stage, endoscopic submucosal dissection techniques must be simulated in isolated animal organs (such as the stomach of pigs), such as injection of fluid under the tumor, annular resection around the tumor. Peeling and hemostasis clips to stop bleeding. This simulation has the practical and achievable steps (2, 3, 4). The third stage is advanced to live animals (live pigs under endoscopic surgery under general anesthesia). The exercises at this stage can achieve the following advantages. (-) It is effective and effective. The lesion can be identified under direct vision. You can practice the basic transfer described previously. (2) Tree: The artificial material _ membrane lesion model is affixed to the human ethics 4 Lai, the stomach phantom Wei can operate, can save the time of preparation of isolated animal organs (such as pig's stomach) and living animal experiments. (3) Convenience: The artificial material mucosal lesion model can be attached to the artificial organ model to connect the goggles and the light source host. "Lion _ secret" (the stomach of the domain) and the inflatable animal equipment required for the live animal experiment fashion to open the corpus, so the operation is not limited to the gastroscope room, so the creation does not have a site limitation. (4) Ren Kun _ membrane lesion model The cost is low and can be repeated. (5) The person's material _ membrane lesion model is clean and has no H odor, and it is not discarded by medical treatment when discarded. (4) New Zealand does not need to sacrifice animals, so there is no ethical consideration.
