Description

Technical Field

[0001] The present invention relates to the technical field of medical device simulation, and in particular to a gastroscope dynamic simulation detection system. Background Art

[0002] Gastroscopy is an important means of diagnosing upper gastrointestinal diseases and is widely used in clinical practice. However, for beginners, mastering gastroscopy techniques requires a lot of practical experience. Traditional gastroscopy training usually relies on real clinical cases or animal experiments, but these methods have many limitations.

[0003] Using real clinical cases for training may cause unnecessary risks to patients, and it is difficult to provide a standardized training environment due to the large individual differences among patients. Although animal experiments can simulate the conditions of the human digestive tract to a certain extent, the digestive tract structure and physiological characteristics of animals are still different from those of humans, and cannot fully and truly reflect the actual situation of human gastroscopy.

[0004] In addition, the existing gastroscopy simulation detection systems on the market are still insufficient in terms of function and simulation authenticity. For example, some systems are not realistic enough in simulating the human digestive tract and cannot accurately simulate physiological phenomena such as esophageal peristalsis and gastric juice secretion; in terms of lesion simulation, the lesion setting and identification functions are not perfect enough to meet the diverse training needs; at the same time, there is a lack of effective evaluation and feedback mechanism, which makes it impossible to accurately evaluate and guide the user's operation, which is not conducive to improving the training effect.

[0005] Therefore, it is of great practical significance to develop a gastroscopic dynamic simulation detection system that can more realistically simulate the gastroscopy process and has complete lesion simulation, operation evaluation and feedback functions. Summary of the invention

[0006] The purpose of the present invention is to provide a gastroscope dynamic simulation detection system to solve the above problems existing in the existing gastroscope examination training and realize more realistic and efficient gastroscope examination training. In order to achieve the above purpose, the present invention provides a gastroscope dynamic simulation detection system, which specifically includes the following components: a simulated human digestive tract model unit: used to simulate the digestive tract morphology and structure of a real human body, including an esophageal simulation part, a stomach simulation part and a duodenum simulation part, and the esophageal simulation part, the stomach simulation part and the duodenum simulation part are connected in sequence.

A pressure sensor is provided at the front end of the scope body of the gastroscope simulation device unit, which is used to detect the pressure between the front end of the scope body and the inner wall of the simulated human digestive tract model unit, and transmit the pressure information to the image display and processing unit for display, so that the user can adjust the operation force to avoid damage to the simulated digestive tract. The image display and processing unit also includes a simulated endoscopic image generation module, which can generate simulated endoscopic images according to the preset human digestive tract anatomical structure and pathological characteristics, which is used for pre-training preview and familiarization with the operation process to improve training efficiency.
