The invention relates to a multidirectional-irradiation passive optical fiber end for medical clinical treatment. The multidirectional-irradiation passive optical fiber end comprises a multimode optical fiber core, a cladding, a coating layer, a lens and a protective cover. The multidirectional-irradiation passive optical fiber end is characterized in that the cladding wraps the optical fiber core, a concave flat deep groove is arranged between the optical fiber core and the cladding, the bottom of the concave flat deep groove extends at the position d2 of 1 / 2 from the critical side of the optical fiber core and the cladding to the fiber core center, a conical lens is adhered in the concave flat deep groove, and the protective cover is fixed outside the cladding. The multidirectional-irradiation passive optical fiber end has the advantages that lateral output radius of medical laser is effectively lengthened, a transmission area of transverse laser lines is enlarged, medical utilization rate of single-beam optical fibers is increased, and curing area and medical clinical treatment effect in the medical clinical laser field are effectively enlarged and improved.
Description
technical field [0001] The invention relates to an optical fiber end for medical clinical treatment, in particular to a multi-directional irradiating passive optical fiber end for medical clinical treatment. Background technique [0002] At present, in order to improve the laser beam output of a single multimode fiber in multiple directions, beveled fiber ends, spherical fiber ends, tapered fiber ends and other structures are usually used, and the output laser has limitations in the laser clinical healing range. Therefore, it is necessary to precisely shape the end of the single-bundle multimode fiber to further improve the multi-directional laser output of the single-bundle multimode fiber. The Korean patent discloses a bundling technology of medical multimode optical fibers, which bundles oblique multimode optical fibers and uses multimode fiber beam splitters to realize laser output. This technology realizes multi-directional laser transmission, but reduces the The utili...
