Background technique
In the medical instrument for combining photosensitive drug treatment tumour, dispersion fiber is commonly used, structure includes and transmission light
The silica fibre of fine end connection, by silica fibre by transmission fiber conduction come laser be scattered, the laser of scattering
It is irradiated to photosensitive drug, excitation photosensitive drug generates drug effect, achievees the purpose that treat tumour.Currently used dispersion fiber is main
It is divided into two kinds, one is columns（Item）For shape in addition, one is dotted, it is real that when treatment, which usually requires optical fiber extending into inside of human body,
To the positioning at scattering end when existing CT scan, the both ends for scattering end are respectively equipped with anchor point, such as Chinese patent application
" a kind of dispersion fiber " disclosed in CN201220732021.9 discloses the patent for using copper or aluminum material as scattering end anchor point,
Since copper and aluminium are less obvious in CT scan, it is not easy to be accurately positioned.The Chinese patent CN of applicant's earlier application
201710037316.1 disclose a kind of copper tantalum alloy and its positioning application on optical dynamic therapy optical fiber, are taken with copper tantalum alloy
More accurate positioning is realized for copper or aluminium, but since copper tantalum alloy is expensive and preparation is not easy, also limits its use,
Therefore a kind of anchor point of new type is needed to be accurately positioned to realize.
Summary of the invention
Against the above deficiency, the present invention provides a kind of apparent dispersion fiber of positioning.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of apparent dispersion fiber of positioning includes transmission fiber and positioned at the scattering end of the transmission fiber front end, described
The both ends at scattering end are provided with positioning ring, the positioning ring include circular core and be wrapped in outside the core every
Absciss layer, the core are made of metallic lead.
Further, the separation layer is made of plastics or resin.
Further, the plastics are polyethylene, polypropylene, polyvinyl chloride, acrylonitrile-butadiene-styrene (ABS), polytetrafluoro
One of ethylene.
Further, the resin is PMMA resin.
The present invention also provides a kind of preparation methods of above-mentioned apparent dispersion fiber of positioning, include following steps：
Step S1：The covering of transmission fiber front end and coat are removed, leave fibre core only to form the scattering end；
Step S2：The core is inserted in both ends and the fixation at the scattering end；
Step S3：One layer of plastics or resin are coated in the core surface by spraying or hot formed mode, described in being formed
Separation layer, the core and separation layer form the positioning ring.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention provides a kind of apparent dispersion fiber of positioning, fixed
Include the core made of metallic lead in the ring of position, since metallic lead is not easy to be penetrated by X-ray, is imaged in CT scan bright
It is aobvious, it can accurately be positioned；And cost is relatively low for metallic lead, is easily obtained, and advantageously reduces cost.The present invention also provides above-mentioned
The preparation method of apparent dispersion fiber is positioned, this method step is simple, and process is easy, is easy to batch and prepares.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, required use in being described below to embodiment
Attached drawing be briefly described.
Fig. 1 is the structural diagram of the present invention.
Wherein, label as shown in the figure for：1：Transmission fiber；11：Covering；12：Coat；13：Fibre core；2：Scatter end；3：
Positioning ring；31：Core；32：Separation layer.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of positioning apparent dispersion fiber, includes transmission fiber 1 and positioned at transmission fiber front end
End 2 is scattered, the both ends at scattering end 2 are provided with positioning ring 3, and positioning ring 3 includes circular core 31 and is wrapped in core 31
External separation layer 32, core 31 are made of metallic lead.Separation layer 31 is made of plastics or resin.When select plastics as isolation
31 when preparing raw material of layer, plastics are polyethylene, polypropylene, polyvinyl chloride, acrylonitrile-butadiene-styrene (ABS), polytetrafluoroethylene (PTFE)
One of；When selecting resin as separation layer 31 when preparing raw material, resin is PMMA resin.Above-mentioned material to human body without
Evil, and it is cheap, it is also easy to molding preparation.
