Guidance system for a near-infrared fluorescein angiography operation with a 785nm continuous wavelength light source

摘要

A guidance system for a near-infrared fluorescein angiography operation with a 785 nm continuous wavelength light source is provided. The guidance system includes a near infrared continuous laser emitting source, a visible light illumination source, a light collector, a light splitter connected to the light collector, a visible light filter, a near infrared filter, a color camera connected to the light splitter via the visible light filter, a near infrared camera connected to the light splitter via the near infrared filter, a terminal display, and a shell configured to contact with the body tissue of the patient. The near infrared to continuous laser emitting source and the visible light illumination source are provided on a light source support in the shell. The shell is provided therein with a viewing channel which is connected to the light collector. Both the color camera and the near infrared camera are connected to the terminal display.
