Detailed Description

The following description will further specifically explain embodiments of the present invention by referring to the accompanying drawings.

Preparation before use:

hard tube endoscopy is a conventional examination method for examining pathological changes in the anorectal cavity of a patient in an anorectal department clinic. Preparation for cleaning the intestinal tract before examination is important because unclean intestinal tract directly affects observation, and pathological changes are missed, so that examination fails. At present, the outpatient service generally adopts an enema method to clean the intestinal tract. The examination is performed without anesthesia, and patients with anal sphincter spasms or nerve sensitivity may be sedated. Before examination, the instrument is prepared, and before examination, the digital anus examination is performed to know whether the anus is provided with the lump, the pressure pain, the tube collision and the wave motion and the tension of the anus dilator. For those with anal fissure, the examination should be suspended if the patient does not need the examination. And (3) checking a cold light source: the cold light source is checked, a starting test is carried out according to the specifications of the cold light source product, whether the instrument is normal or not, whether the light guide beam is correctly connected or not, whether the illumination is adjustable or not and the like.
