Description

Gastroenterology gastroscope

Technical Field

The utility model belongs to the technical field of medical equipment and specifically relates to a gastroenterology gastroscope.

Background

Gastroscopy is a medical examination procedure. It uses a black plastic coated light-conducting fiber slender tube with a diameter of about one centimeter, and its front end is equipped with an endoscope which is extended into the esophagus, stomach and duodenum of the examined person from the mouth, and the light can be turned by means of the strong light emitted from light source and light-conducting fiber, so that the doctor can clearly observe the health condition of every position in the upper digestive tract from another end. The gastroscopy can directly observe the real situation of the detected part, and can carry out pathological biopsy and cytology detection on the suspicious lesion part to further clearly diagnose, so that the gastroscopy is the preferred detection method for the upper digestive tract lesion. And because the alimentary canal is soft and sensitive, need to keep gastroscope hose outside lubricated at any time, but traditional lubrication method mostly stretches into the examinee in vivo behind the external lubrication hose, and the lubricated liquid in hose outside can inevitably adhere to dust and bacterium in the air in this in-process, is difficult to keep clean health.
