Description
Technical field
Treated the present invention relates to a kind of clinical medicine treatment optical fiber connector, more particularly to a kind of clinical medicine with multi-direction
Irradiate passive fiber end.
Background technology
At present, exported to improve single beam multimode fibre in multidirectional laser beam, generally use oblique angle optical fiber connector,
Ball-type optical fiber connector, the structure such as conical fiber end, it exports laser and there is limitation on laser clinical cure interval.Therefore
Need to carry out precision truing to single beam multimode fibre end, could further improve single multidirectional laser of beam multimode fibre defeated
Go out.A kind of bundled technology of medical multimode fibre of Korean Patent Publication, multimode fibre point is utilized by the binding of oblique angle multimode fibre
Beam device realizes that laser is exported, and this technology realizes the transmission of multi-direction laser, but reduces the utilization ratio of single beam multimode fibre,
And be also easy to produce in use multiple beams of optical fiber winding transition cause optical fiber to be damaged, cause malpractice.Chinese patent is disclosed
A kind of processing method for high precision optical fibre lens, polishes method to optical fiber connector processing, this method is at light end using manual machinery
Processing intensity and machining angle propose very high requirement to optical fiber connector inner hardness during the inside processing of end.
The content of the invention
In view of the problem of above-mentioned prior art is present, it is passive with multi-direction irradiation that the present invention provides a kind of clinical medicine treatment
Optical fiber connector, is conducive to the multidirectional output of medical laser, and the utilization rate that will improve the medical multimode fibre of single beam.Specific skill
Art scheme is that a kind of clinical medicine treatment irradiates passive fiber end, including multimode fibre fibre core, covering, coating with multi-direction
Layer, lens, protective cover, it is characterised in that：Covering is wrapped in outside fiber core, there is recessed flat deep trouth between fiber core and covering,
The bottom of recessed flat deep trouth fiber core and covering critical surface to d at the 1/2 of core centre2, holosraphic grating is adhered to recessed
Inside flat deep trouth, protective cover is fixed on outside covering.
Described fiber core is that a diameter d is 200 microns~800 micron multi-mode optical fiber fibre cores.
Described recessed flat deep trouth bottom is plane, and area is multimode fibre core centre point to multimode fibre fibre core and covering
Critical surface 1/2 position d2Circular area, diameter d1For 100 microns~400 microns, recessed flat deep trouth oblique angle is derived as being less than
39 degree.
Described lens are pyramid type, and bottom is plane, and coning angle is more than 90 degree, the basal diameter d of Conical Lenses1For
100 microns~400 microns.
Described protective cover inside diameter is 250 microns~1000 microns, and outer dia is 500 microns~1400 microns,
Shape, material are quartz glass protective cover, metal noncontact protective cover, metal noncontact protective cover, in optical fiber connector using resistance to
High-temp glue fixes protective cover.
The solution have the advantages that effectively increasing the lateral output radius of medical laser, improving the horizontal straight line of laser
Transmission region, improve the fine medical science utilization rate of single beam, effectively improve healing area in laser medicine clinical field
With clinical medicine therapeutic effect.
