Description
Technical field: [0001] The invention relates to a measuring instrument, in particular to an optical fiber detection head of a medical intrinsic fluorescence diagnostic instrument, in particular to a commutator for an optical fiber detection head of an intrinsic fluorescence diagnostic instrument. Background technique: [0002] In the prior art, the optical fiber detection head of the medical inherent fluorescence diagnostic instrument is generally used clinically to detect human body lesions. The detection part, therefore, requires a large operating space, and some parts of human tissue have a narrow space, which is not conducive to the operation of the optical fiber detection head. Invention content: [0003] The technical problem in the prior art to be solved by the present invention is: since the optical fiber detection head and its accompanying optical fiber in the prior art are perpendicular to the detected part of the human tissue, a large operating space is require...
