Based on high image quality and definition, the endoscope can be used for fine operations which are difficult to operate by the traditional endoscope, such as neurovascular operations. Meanwhile, based on the characteristics of clear display or identification of membranous anatomical layers, tiny blood vessels, nerves, lymph node cleaning range boundaries and the like, the method has more practical value in operations such as stomach, colorectal, pancreas, thyroid, weight reduction, hernia and the like.

The invention can accelerate the operation process and reduce the pain time of patients through the image setting information and the light source configuration information recorded in the database.

The image setting of the display is adjustable, so that the operation efficiency of the surgery is improved, and the accurate judgment of a surgeon on a focus is promoted.

The traditional remote consultation and teaching are taken as important supplementary means, and the medical information transmission is carried out by adopting two-dimensional information such as common videos, photos and the like. But the two-dimensional information reflects a complex three-dimensional structure of a human body, has larger limitation on accuracy and safety, is far from medical grade professional requirements of 'lossless image quality and no time delay' of remote video transmission, can help a basic-level doctor to better master medical theoretical knowledge and operation skills, greatly increases opportunities and capabilities of the basic-level doctor in practical operation, and promotes further improvement of medical training quality.

The cold light source and camera system integrated machine is designed, so that the performance problems of emission, disturbance resistance and the like are greatly reduced; the design of the integrated machine reduces the trouble of complicated machine control and machine-to-machine matching of surgical equipment;

the video storage module can be used as courseware for learning with less experience or more remote doctors in later period;

the invention adds the display panel, not only can verify the delay problem transmitted to the display through HDMI, but also is convenient for the equipment to be used in the outgoing operation
