Abstract

The invention relates to an optical fiber microscopic endoscope probe. The optical fiber microscopic endoscope probe comprises a miniature microscope objective set and an imaging optical fiber bundle. The imaging optical fiber bundle is arranged in rear of the miniature microscope objective set. The miniature microscope objective set comprises a first lens element, a second lens element, a third lens element and a fourth lens element, wherein the first lens element is arranged in the foremost portion of the miniature microscope objective set, the surface of the first lens element is soaked with water, the second lens element is arranged in rear of the first lens element, the third lens element is arranged in rear of the second lens element, and the fourth lens element is arranged in rear of the third lens element and located in front of the imaging optical fiber bundle. The miniature microscope objective set of the optical fiber microscope endoscope probe comprises the four lens elements, the machining and assembling difficulty is greatly reduced, the boundary dimensions are effectively reduced, and the optical fiber microscopic endoscope probe can enter the human body through a work channel of a convectional 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...
