One end of first optical fibre is connected with medical optical fibre probe, its another end is equipped with a first collimator, and one end of second optical fibre is equipped with a second collimator, said first collimator is fixed in a tubular connecting member, and said second collimator is fixed in a column connecting member. Besides, said invention also provides its working principle and its advantages.

Description

Technical field: [0001] The invention relates to a measuring instrument, in particular to a detection optical fiber of a medical diagnostic instrument, in particular to an anti-twist detection optical fiber for an intrinsic fluorescence diagnostic instrument. Background technique: [0002] In the current technology, the optical fiber detection head of the intrinsic fluorescence diagnostic instrument is generally used clinically to detect the lesion site of the human body, and the optical fiber detection head is connected to the medical diagnostic instrument through an optical fiber. During use, the optical fiber probe needs to change its direction frequently, and the diameter of medical optical fibers is usually small, and its ability to resist twisting stress around the axial direction is not high, so the optical fiber is easy to break and affects the service life. Invention content: [0003] The technical problem in the prior art to be solved by the present invention is:...
