Abstract

The invention discloses a microscopic endoscope system which comprises an illuminating unit, a camera shooting and image processing unit, an endoscope microscopic probe, an optical fiber image transmitting bundle and an image output and illumination input unit. The illuminating unit provides illumination light for an endoscope; the camera shooting and image processing unit shoots a body tissue image and processes the image; the endoscope microscopic probe enters the body cavity through a pincers channel hole of the endoscope system and carries out microimaging on the target tissue; the optical fiber image transmitting bundle transmits a target image formed through the endoscope microscopic probe; the image output and illumination input unit couples illuminating light output by the illuminating unit into the optic fiber image transmitting bundle and inputs the image transmitted out by the optic fiber image transmitting bundle into the camera shooting and image processing unit. The system solves the problems that an endoscope system in the prior art is low in imaging override, and the morphologic change and the cell microstructure of the tissue can not be observed.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a microendoscope system. Background technique [0002] Medical endoscope is a common medical device, which can generally enter the body through the natural passages of the human body, such as the oral cavity, nasal cavity, etc., or through small incisions made artificially on the human body, so as to realize the inspection of diseased organs in the human body. In recent years, the clinical endoscopic technology has made great progress, such as high-definition endoscopy, zoom endoscopy and narrow-band imaging endoscopy (Narrow-band Imaging, NBI) and so on. These new technologies can achieve clearer imaging of the lesion, magnify the imaging of the lesion, or highlight the microvascular structure of the lesion. The disease detection rate of endoscopy has been further improved. [0003] For example, Chinese patent CN200780016642 provides an image processing device for an endosco...
