Apex for an optical fiber array, surgical instrument and laser unit comprising this apex

摘要

The invention relates to an apex (1, 1 ', 1 ") for an optical waveguide arrangement (2), which guides light (3) from a proximal end (PE) to a distal end (DE) for a therapeutic treatment of the human or animal body , a surgical instrument (100, 110), a catheter (120) and a laser unit (200) comprising this apex (1, 1 ', 1 "). Finally, the invention relates to the use of optical waveguide arrangements which have an optical grating, for example in the form of a fiber Bragg grating (FBG), for constructing such an apex (1, 1 ', 1 "). According to the invention, this light is brought together from more than one light source (LD) in the region of the treatment site, wherein light from a first source (LD) is therapeutic light with high optical energy density, and light from a second source light for detecting a physical parameter in the area the treatment site is. Due to these characteristics, the range of applications is spreading.
