Full-thickness resection model box for endoscopic submucosal dissection (ESD) of stomach

Abstract

The invention provides a full-thickness resection model box for endoscopic submucosal dissection (ESD) of a stomach, which is composed of a simulated esophagus, a nylon buckle, an electrode pad, an elastic rubber band, three traction clips, a simulated abdominal cavity box, and a duodenum sealing buckle, wherein the simulated esophagus passes through the simulated abdominal cavity box; the nylon buckle is fixed at one end of the simulated esophagus; the three traction clips are fixed at two sides of the simulated abdominal cavity box through the elastic rubber band; and the electrode pad is attached to the outer wall of a sample for an experiment. The design is reasonable, the making material is easy to obtain, the making is simple, and the cost is low. The full-thickness resection model box for endoscopic submucosal dissection of the stomach is suitable for training a beginner to perform endoscopic submucosal dissection, a stomach full-thickness resection technique and gastric perforation emergency treatment, simulates a sealed abdominal cavity environment in the case of gastric wall full-thickness resection perforation and is a model for ESD training with the using effects close to the actual state of clinical operation. The relatively-sealed abdominal cavity environment in the case of full-thickness resection perforation can be simulated, and the three traction clips are used to simulate the supporting role of main zonules such as hepatogastric ligament, thereby being close to clinical practice.

Description

technical field [0001] The invention belongs to a teaching model, and relates to a full-thickness resection model box of gastric endoscopic submucosal dissection (ESD), which is a training model for endoscopic submucosal dissection (ESD) and full-thickness resection of gastric wall. Background technique [0002] China is a country with a high incidence of gastric cancer. On the basis of the increasing popularity of NBI, magnifying endoscopy, and chromoendoscopy, and the gradual improvement of the level of endoscopic diagnosis and treatment, and based on the large number of gastroscopy examinations each year, domestic gastroenterologists and gastroenterologists are currently The number of cases of early gastric cancer detected by endoscopists is also increasing year by year. Endoscopic submucosal dissection (ESD), as a new minimally invasive treatment technique, has been gradually and widely used in clinical practice, expanding the scope of indications for endoscopic submucos...

AI Technical Summary

Problems solved by technology

Using experimental animals for ESD training can be a good way to train ESD operations and is very similar to actual clinical work, but the preparation process for animal experiments is cumbersome, expensive, and requires certain animal breeding conditions, so it is not easy to popularize

The commonly used ESD training model we currently use simply puts the pig stomach in the model, which is difficult to simulate the relatively airtight environment of the abdominal cavity during full-thickness resection and perforation, and does not reflect the supporting role of the stomach in the main suspensory ligaments in the abdominal cavity. The actual gap is too large
