Gastroscope-teaching simulation model

Abstract

The invention discloses a gastroscope-teaching simulation model. The gastroscope-teaching simulation model comprises a stomach model, a tumor model and a polyp model, wherein the stomach model is in an equal proportion to the stomach part of a human body; the stomach model is internally provided with the tumor model and the polyp model; the tumor model comprises a spherical airbag, a connecting pipe, a control valve and a needle bolt; the stomach model is provided with a connecting through hole; a connecting pipe is arranged in the connecting through hole in a penetrating manner and penetratesthrough the stomach model; one end of the connecting pipe extends into the stomach model and is connected with the spherical airbag, and the other end of the connecting pipe extends to the outer partof the stomach model and is connected with the needle bolt; the control valve is arranged on the connecting pipe at the outer part of the stomach model; the polyp model and the tumor model are same in structure. The gastroscope-teaching simulation model disclosed by the invention has the beneficial effects that the design is reasonable, the sizes of the tumor model and the polyp model can be adjusted at any time, and the size of the ulcer surface and the depth of the ulcer of an ulcer model also can be adjusted at any time, so that the simulation effect can be effectively improved and the training efficiency is high.

Description

technical field [0001] The invention relates to a medical teaching model, in particular to a gastroscope teaching simulation model. Background technique [0002] Gastroscopy is a method of medical examination and also refers to the equipment used in this examination. Gastroscopy can directly observe the real situation of the inspected part, and can further confirm the diagnosis through pathological biopsy and cytological examination of suspicious lesions. It is the preferred inspection method for upper gastrointestinal lesions. It is inserted into the stomach through a thin, flexible tube, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum, especially for minor lesions. At present, in the process of gastroscopy, doctors use clinical experience to judge the size of tumors and polyps in the stomach, esophagus and intestinal tract of patients, as well as the size and depth of ulcers. It is difficult for interns to judge, and the accuracy is po...

AI Technical Summary

Problems solved by technology

The structure of the lesion model in the stomach model, esophagus model and intestinal model in the prior art is relatively simple, the size of the tumor model and the polyp model cannot be adjusted at any time, and the size of the ulcer surface and the ulcer depth of the ulcer model cannot be adjusted at any time. Poor, low training efficiency
