Abstract

The invention discloses a narrow-band imaging endoscope device which comprises a light source structure, an endoscope structure, an image processing module, a synchronous irradiating assembly and a spectrum light splitting assembly. The light source structure irradiates at least one beam of illuminating light provided with regulated wavelength frequency bands on detected tissue. The endoscope structure photographs an image of the detected tissue irradiated by the illuminating light provided with the regulated wavelength frequency bands. The image processing module processes the image photographed by the endoscope structure. The synchronous irradiating assembly irradiates the illuminating light emitted by the light source structure on the surface of the detected tissue synchronously. The spectrum light splitting assembly splits the light reflected back by the detected tissue and then inputs the light into the image processing module. The narrow-band imaging endoscope device effectively solves the problem that due to motion of the detected tissue, a narrow-band image is distorted, the structure of the endoscope device is simplified, the reliability of the endoscope device is improved, and consumed energy is reduced.

Description

technical field [0001] The present invention relates to an endoscope device, in particular to a narrow-band imaging endoscope device which irradiates the inspected tissue with multiple spectrums of irradiation light and splits the light reflected by the inspected tissue to form images simultaneously. Background technique [0002] Oxygenated hemoglobin and deoxygenated hemoglobin in blood have a strong effect on certain specific narrow-band spectra. Narrow-band imaging endoscopes use this feature to enhance the image of blood vessels in the human mucosa. Traditional electronic endoscopes use broadband white light sources such as xenon lamps or tungsten-halogen lamps as illumination light. Currently, commonly used narrow-band imaging endoscopes add a narrow-band filter after the white light source to filter the broadband white light, leaving only the peak Red, green and blue narrow-band spectra with wavelengths of 600nm, 540nm and 420nm, and transmit the narrow-band spectra to...
