Multi-spectral medical endoscope lens and system

Abstract

The invention discloses a multi-spectral medical endoscope lens and system. The lens comprises four micro lenses, wherein narrow bandpass filters are integrated below the micro lenses and comprise a red filter, a blue filter, a green filter and a visible light cutoff filter, light barrier layers are arranged on the peripheries of the micro lenses and the narrow bandpass filters and used for blocking stray light from incidence, and light isolation layers are arranged at the rear ends of the micro lenses and used for preventing signal harassing among the micro lenses. The system comprises an imaging unit and a displaying unit which are connected, so that multiband images can be acquired simultaneously, and a medical worker can accurately judge the disease position by comparing images under different wave bands; through improvement of the lenses and a light source, images under four bands from visible light to near infrared light can be captured in parallel; the multi-spectral micro lenses are simple in structure and highly integrated and can be easily combined with a small-size endoscope.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multispectral medical endoscope lens and system. Background technique [0002] like figure 1 As shown, the medical endoscope system is mainly composed of an endoscope 1 , an endoscope coupler 2 , an imaging unit 3 , a cable 4 , a camera control unit 5 , and a display unit 6 . [0003] Wherein the endoscope is composed of a bendable part, a light source and a group of lenses. Enter the human body through the natural orifice of the human body, or through a small incision made by surgery. When in use, the endoscope is introduced into the pre-examined organ, and the changes in the relevant parts can be directly observed. The imaging principle of the endoscope is to introduce the light of the cold light source into the guide beam, and a concave lens is installed at the head end of the guide beam (the tip of the endoscope). Light that hits the surface of the organ is ...

Problems solved by technology

However, in this way, the endoscope can only acquire images of one band at a time, which is inconvenient to operate, and there is no contrast between images of different bands, and it is difficult to provide medical staff with more effective image information for diagnosis and treatment.
