Commutator for optical fiber probe of autofluorescence diagnosis instrument

Abstract

The invention discloses a commutator for an optical fiber probe of an autofluorescence diagnosis instrument, comprising a sleeve which is closed at the front end, wherein the sleeve is made of medical silicon rubber material; the side wall of the sleeve is provided with a through hole; a reflecting mirror is arranged in the sleeve and between the axis of the through hole and the front end of the sleeve; an incident light path of the reflecting mirror is overlapped with the axis of the through hole, and an emergent light path of the reflecting mirror is overlapped with the axis of the sleeve. The reflecting mirror comprises a reflecting prism. The inner wall of the sleeve is provided with steps. The sleeve is sleeved in an optical fiber probe, the axial direction of an optical fiber in the optical fiber probe is overlapped with that of the sleeve, the sleeve is supported at a detected part of a tissue of a human body, the through hole aligns to the detected part, and light enters into the through hole along a direction vertical to the axial direction of the optical fiber probe and enters into the optical fiber probe after being reflected by the reflecting mirror. The commutator meets the requirement for an operation space, and meanwhile, the steps arranged on the inner wall of the sleeve can ensure that the positions of the sleeve and the optical fiber probe are constant. The commutator is simple in structure and convenient and safe in use.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to an optical fiber detection head of a medical inherent 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. Contents of the invention [0003] The technical problem solved by the present invention is: because the optical fiber detection head and its accompanying optical fiber in the prior art are perpendicular to the detected part of the human tissue, it requires a large operating space, and some parts of the human tissue have a narrow space. It is not conducive to the operation of the fiber optic probe head. [000...
