Light guides for diagnostic, surgical and / or therapeutic devices

摘要

PROBLEM TO BE SOLVED: To provide an ultrafine light guide for insertion into a human or animal body, or for in vitro examination of a human or animal blood sample or other somatic cells. A light guide 30 has a maximum lateral dimension of a cross section of a fiber bundle, for example, a maximum of 500 μm, preferably a maximum of 200 μm, particularly preferably a maximum of 100 μm, and extremely particularly preferably a maximum of 50 μm. It has a maximum lateral dimension, eg, outer diameter, of the cross section, and the light guide is terminated at least one at the proximal end 40 and the distal end 50 and at least one end 40, 50. It has an end face, and the terminated end face has a maximum lateral maximum outer dimension of the cross section of the light guide 30, for example, a lateral maximum outer dimension of the same size as the outer diameter, for example, an outer diameter. There is. [Selection diagram] Fig. 1
