Endoscope simulation dynamic detection device

Abstract

The invention discloses an endoscope simulation dynamic detection device, which comprises a simulated stomach, which is made of soft material imitating human tissue, and a simulated cardia is provided on the simulated stomach to communicate the inner cavity of the simulated stomach with the outside world; A pressure changing mechanism is provided for changing the air pressure in the simulated gastric cavity or the external air pressure, so as to cause the simulated stomach to generate internal and external pressure difference so as to make it shrink or expand; the inner wall of the simulated stomach is provided with at least one endoscopic observation standard part. The beneficial effect of the present invention is that the internal physiological environment of the human stomach is simulated by the model, the simulated stomach is contracted or expanded by the pressure changing mechanism to simulate the peristalsis of the stomach, and the endoscopic observation standard part is set as the target of gastroscopic observation under the simulated environment Compared with conventional in vitro tests, this device can provide a more realistic physiological scene for dynamically judging the resolution performance of the gastroscope, and investigate the bending ability and operational performance of the gastroscope fiber, making the test results closer to the observation results in the real physiological environment .

Description

technical field [0001] The invention belongs to an in vitro simulation system for internal organs of a human body used for detection of endoscope imaging equipment, in particular to an endoscope simulation dynamic detection device. Background technique [0002] Medical endoscope is a kind of common medical detection instrument, which has image sensor, optical lens, light source lighting, mechanical device, catheter, etc. It can enter the body through natural or artificial channels of the human body. With the help of an endoscope, doctors can visually observe the surface structure of mucosal tissue or internal organs in the human body. Gastroscope is the most commonly used clinical endoscope for gastric inspection. It enters the stomach through the oral cavity, esophagus or artificial hole, so that doctors can observe diseases in the stomach. As a medical device, a gastroscope must undergo strict testing before it is put into the market to evaluate its functional performance...

AI Technical Summary

Problems solved by technology

However, in actual use, the gastroscope lens faces a more complex environment inside the stomach, such as the dark environment of the gastric cavity, gastric movement, gastric acid liquid environment, etc. These factors interfere with the observation of the target point, so the actual resolution of the gastroscope It is greatly affected by the environment, and only the direct observation of the resolution standard in vitro cannot reflect the true resolution performance of the gastroscope

However, there is currently no device that can simulate the internal environment of the stomach, and it is impossible to realize the dynamic detection and evaluation of the endoscope
