Bronchoscope system with night vision function

Abstract

The invention belongs to the field of medical apparatuses and instruments, and relates to a bronchoscope system with a night vision function. The bronchoscope system comprises a bronchoscope and a monitor, wherein the bronchoscope is provided with a night vision camera system provided with a night vision function processing mainframe; the bronchoscope system further comprises an optical lens system connected with a cold light source mainframe and an ordinary camera mainframe. Infrared rays radiated by the tracheal cavity or the tracheal wall are actively or passively captured by the night vision camera system inside the bronchoscope, so that the redundant light interference in the traditional bronchoscope can be effectively prevented, and a doctor can truly know tissue stations in the bronchoscope by obtaining the night vision images of the inner part of the tracheal cavity in either a dark condition or a shimmer condition; and meanwhile, potential information such as diseases uneasily acquired by the observation of the traditional bronchoscope can be obtained by analyzing and comparing the night vision images with the images of tracheal cavity in the light condition, so that the ways of bronchoscope observation and diagnosis can be enriched and supplemented.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a bronchoscope 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 bronchoscopes are all under the condition of light. Doctors observe the appearance of the inside of the trachea through the optical system of the bronchoscope. At present, there is no bronchoscope system with night vision function.
