Abstract

The present invention relates to a fiber optic microendoscopic probe, comprising: a miniature microscopic objective lens group and an imaging optical fiber bundle, the imaging optical fiber bundle is arranged behind the miniature microscopic objective lens group; the miniature microscopic objective lens group includes: The first lens element, the second lens element, the third lens element and the fourth lens element; wherein, the first lens element is arranged at the forefront of the miniature microscopic objective lens group, and the surface is soaked in water, and the second lens element is arranged on After the first lens element, the third lens element is arranged behind the second lens element, and the fourth lens element is arranged after the third lens element and in front of the imaging fiber bundle. The miniature microscopic objective lens group of the optical fiber microendoscopic probe of the present invention includes four lens elements, which greatly reduces the difficulty of processing and assembly, and effectively reduces the external dimension, so that it can enter the inside of the human body through the working channel of the conventional endoscope.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an optical fiber microscopic endoscopic probe. Background technique [0002] Confocal endoscopic microscopy is one of the latest endoscopic imaging technologies. It can perform in vivo high-resolution imaging during ordinary endoscopic examinations, obtain real-time histological imaging results of the mucosa, and provide clinical diagnosis and cancer prevention for doctors. provide help. [0003] Among them, the fiber optic microendoscope probe is one of the key technologies of the confocal microendoscope. It is used to focus the divergent light emitted by a single fiber of the fiber bundle on the sample to excite fluorescence, and collect the fluorescence generated by the sample. A single fiber that enters the fiber bundle. [0004] Existing optical fiber microscopic endoscopic probes, as described in the patent document of China Patent Application No. 200510029661.8, publish...
