Esophagoscope system with night vision function

Abstract

The invention belongs to the field of medical appliances, and relates to an esophagoscope system with a night vision function. The esophagoscope system comprises an esophagoscope, a monitor and an optical lens system, wherein a night vision shooting system is arranged on the esophagoscope; a night vision function processing host machine is connected with the night vision shooting system; and a cold light source host machine and a common shooting host machine are connected with the optical lens system. In the esophagoscope system provided by the invention, the night vision shooting system arranged inside the esophagoscope actively or passively captures the infrared radiated by the esophagus tract and among the walls, the excess light interference of the tradition esophagoscope is effectively avoided, and the night vision image inside the esophagus tract is obtained under the condition of no light or dim light, thus a doctor can more veritably gather the status of the esophagus tract and the inter-wall tissues; and at the same time, through analyzing and contrasting the night vision image and the esophagus tract and inter-wall image under the condition of light, disease symptom and other latent information, which is not easy to obtain under the observation of the tradition esophagoscope, can be obtained, thus the diagnosis means of esophagus diseases is further enriched and supplemented.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an esophagoscope 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.

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 esophagoscopes are all under the condition of light. Doctors observe the appearance of the inside of the esophagus through the optical system of the esophagoscope. There is no esophagoscope system with night vision function yet.
