The invention discloses an
endoscope system adopting an RGB + NIR single sensor and having a
hemodialysis and
fog penetration function, and relates to the technical field of
medical imaging, the
endoscope system comprises a
handle, the left end of the
handle is connected with an
endoscope tube body, and an optical lens, an
image sensor and an
image processing circuit are installed in the
handle or the endoscope tube body; the
image sensor adopts a
CMOS image sensor of a monolithic integrated visible light (RGB) and near-
infrared (NIR)
light sensing unit, and a visible light image and a near-
infrared image can be obtained at the same time; the installation of the optical lens, the image sensor and the
image processing circuit has two implementation structures: 1, in an optical endoscope scheme, the optical lens, the image sensor and the
image processing circuit are installed inside the handle, and the endoscope tube body transmits an
optical image into the handle; 2, in the scheme of the electronic endoscope, the optical lens and the image sensor are arranged at the front end in the endoscope tube body,
direct imaging is carried out in the body, and the image
processing circuit is arranged in the handle; the image
processing circuit fuses the visible light image and the near-
infrared image, a fusion
algorithm dynamically adjusts RGB and NIR
signal weights according to an operation scene, and high-contrast clear imaging is achieved in a bleeding, smog or
liquid medium environment. The endoscope adopting the RGB + NIR single sensor and having the
hemodialysis and
fog penetration functions is suitable for minimally
invasive surgery scenes such as a
thoracoscope, a laparoscope and an arthroscope.
