[0001] The present invention relates to the technical field of medical clinical examination instruments, and in particular to a digestive endoscope with a self-draining structure and an application method thereof. Background Art

[0002] At present, precision medical equipment such as digestive endoscopes are often used in clinical medicine for diagnosis and treatment of the human digestive tract. Existing digestive endoscopes are usually equipped with a nozzle and an endoscope surface at their head end. The main function of the nozzle is to regularly inject air and water into the corresponding gastrointestinal cavity when using the endoscope for examination, so as to expand the gastrointestinal cavity and clean the endoscope surface. However, since the human gastrointestinal cavity contains a lot of secretions and some blood, the secretions and blood are easy to solidify and crystallize on the inside of the nozzle, resulting in blockage of the nozzle channel, thereby reducing the amount of air and water injection, which seriously affects the subsequent normal examination of the digestive endoscope.
