Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of endoscopes, in particular to a liquid inlet component of an endoscope. Background Art
[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has an image sensor, optical lens, light source, mechanical device, etc. It can enter the stomach through the mouth or enter the body through other natural orifices. An endoscope can be used to see lesions that X-rays cannot show, so it is very useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and develop the best treatment plan accordingly. When a medical endoscope is in use, an auxiliary water delivery device will be used to deliver medical fluids into the patient's body to flush tissues to remove blood, excrement and other organic matter to improve the visibility of diagnosis and treatment.
