Abstract

The invention discloses a fluorescent guidance endoscope system based on focusing feedback and an automatic laser power adjusting method. By reading position data of a motor after automatic focusing,the power of output light is adjusted in real time; the requirements for image brightness are met, and meanwhile, tissue can be prevented from being irradiated by lasers with high power and density for a long time, so that damage caused by the lasers to the biological tissue is alleviated.

Description

technical field [0001] The invention relates to a fluorescent navigation endoscope, in particular to a fluorescent navigation endoscope system based on focusing feedback and a laser power automatic adjustment method. Background technique [0002] In some functional endoscopic imaging systems, lasers are used as special lighting sources, such as ICG fluorescence imaging. In order to ensure the overall functional imaging effect, the laser power required by the system is relatively large. The output laser power of the existing system is set at a constant value. When it is necessary to observe details close to the tissue, the illumination area becomes smaller, and the received light power per unit area (ie, irradiance) increases, which may cause burns or other irradiance. biosecurity issues. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The purpose of the present invention is to provide a fluorescence navigatio...
