Electronic colonoscope system having night vision function

Abstract

The invention belongs to the field of medical appliance, which relates to an electronic colonoscope system having a night vision function. The system comprises an electronic colonoscope, a monitor, a night vision camera system arranged on the electronic colonoscope, a night vision function processing host computer connected with the night vision camera system, an optical lens system, and a cold light source mainframe and a common camera mainframe connected with the optical lens system. The invention actively or passively captures infrared ray radiated from the colonic tract and interwalls by using the night vision camera system in the electronic colonoscope, which effectively prevents excess light disturbance of the conventional electronic colonoscope, and acquires a night vision image of the colonic tract and interwalls under the condition of no light or weak light, to thereby make doctors really known tissue states of the colonic tract; meanwhile, by analyzing and comparing the night vision image with a colonic tract image under the light condition, disorder latent information difficultly acquired by observing under the conventional electronic colonoscope can be acquired, and diagnosis means of colonic tract diseases are further supplemented.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an electronic colonoscope system with night vision function. Background technique [0002] There are currently two main working methods for night vision imaging technology. The first is the image enhancement method. This technology can collect weak light, including the low region of the infrared spectrum (even if the light in this region exists, it cannot be seen by the naked eye) , and then magnify it to a certain level so that people can clearly observe the image; the second is infrared thermal imaging technology, which can capture the upper part of the infrared spectrum, that is, the light emitted by objects in the form of heat dissipation. Non-reflected light, warmer objects such as a human body emit more infrared light than cooler objects such as trees or buildings.

AI Technical Summary

Problems solved by technology

[0003] Most traditional endoscopic systems use cold light sources as the medium of endoscopic illumination, and obtain images of human organ cavity tissues through traditional prism optical systems or electronic CCD optical systems, which are used as the basis for diagnosing human organ diseases. The disadvantage of this method is that the visible lesions in the general human organs can be directly diagnosed by naked eye observation, but some potential diseases do not show visual characteristics, so even the images fed back by the endoscope cannot be diagnosed , which must be obtained by taking tissue biopsy, etc.

[0004] Existing electronic colonoscopes are all under the condition of light. The doctor observes the appearance of the inside of the colon through the optical system of the electronic colonoscope. At present, there is no electronic colonoscope system with night vision function.
