An endoscope is a commonly used medical instrument and consists of a bendable part, a light source and a group of lenses. Enter the human body through natural orifices of the human body or small incisions made by operation. When in use, the endoscope is introduced into the pre-examined organ, and the change of the relevant part can be directly observed. The quality of the image directly affects the using effect of the endoscope and also marks the development level of the endoscope technology. The earliest endoscopes were applied to rectal examination. The doctor inserts a hard tube into the anus of the patient and observes the pathological changes of the rectum by means of the brightness of the candle. This method has limited diagnostic data available, is painful for the patient, and poses a significant risk of perforation due to the rigid apparatus. Because of these shortcomings, endoscopy continues to be used and developed, and many different uses and types of instruments are being designed.
