Background

The endoscope is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics and software into a whole. One has an image sensor, optical lens, light source illumination, mechanical device, etc. that can enter the stomach orally or through other natural orifices. The classification is carried out according to different positions reached by the endoscope: can be divided into otolaryngological endoscope, oral endoscope, dental endoscope, neuroscope, urethrocystoscope, resectoscope, laparoscope, arthroscope, laryngoscope, gastrointestinal endoscope and the like. The gastrointestinal endoscope can enable a patient to complete the whole examination and treatment process in a painless state, the examination and treatment time is short, and the patient can quickly go home after the examination and treatment.

When the endoscope such as a gastrointestinal endoscope is used, the heat transfer coefficient of the endoscope is greatly different from that of human tissues because the main materials of the endoscope are generally glass, metal and the like, and when the endoscope works in a human body, because the temperature of the endoscope is always lower than the environment of the human body, water vapor in the human body is easy to condense on the surface of a lens of the endoscope in an operation, so that the fogging phenomenon is generated, and the image quality is influenced. Surgical instruments such as electrosurgery and electrocoagulation which are commonly used in modern surgical operations generate certain smog in use, wherein the smog also contains fat particles, human tissues and the like besides water vapor, and the smog is also easy to condense on the surface of a lens of an endoscope, so that the image quality is influenced.

In addition, the conventional endoscope generally has a single optical fiber or a single camera, images are two-dimensional plane images, the two-dimensional plane images are difficult to reflect the depth of organs and the like, and an operator cannot intuitively form a three-dimensional spatial distance sense.
