Abstract
The invention discloses a kind of dispersion fibers being easy to positioning, are related to the field of medical instrument technology, solve the problems, such as that longer scattering end positioning is inaccurate.It is easy to the dispersion fiber of positioning, includes Transmission Fibers and the scattering end positioned at the Transmission Fibers front end, covered on the scattering end there are three locating ring, two of which is located at the both ends at the scattering end, another is located at the middle part for scattering end.The present invention provides through three locating rings are arranged on scattering end, using the position relationship of three locating rings, the Position Approximate at scattering end can be extrapolated, to realize the positioning at scattering end, the positioning particularly suitable for the longer scattering end of length.
Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of dispersion fibers being easy to positioning.
Background technology
In the medical instrument for combining photosensitive drug to treat tumour, dispersion fiber is commonly used, structure includes and transmission light
The silica fibre of fine end connection, by silica fibre by Transmission Fibers 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）In addition, one is dotted, when treatment, usually requires optical fiber extending into inside of human body shape, is real
To the positioning at scattering end when existing CT scan, the both ends for scattering end are respectively equipped with anchor point.This mode be very suitable for scattering end compared with
Short situation.If but in order to increase spread（Increase laser action range）, length is done at scattering end, then since optical fiber is thin
It is soft, it is extremely easily bent, deforms, therefore deformed scattering end（Two locating ring middle sections）Specific, actual bit be equipped with
When be not it is clear that length it is longer scattering end positioning still need to be improved.
Invention content
For the above deficiency, the present invention provides a kind of dispersion fiber being easy to positioning.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
A kind of dispersion fiber being easy to positioning, includes Transmission Fibers and the scattering end positioned at the Transmission Fibers front end, described
It scatters and is covered on end there are three locating ring, two of which is located at the both ends at the scattering end, another is located in the scattering end
Portion.
Further, the locating ring is provided with tapered slope on the side of the front end far from the scattering end.
Further, it is arranged with plastotype sleeve flexible on the scattering end, the plastotype sleeve is by polymethylacrylic acid
Methyl esters is made.
Further, the direction axially outside of the plastotype sleeve offers a plurality of guide groove, the guide groove and institute
The axial direction for stating plastotype sleeve is perpendicular.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention provides a kind of dispersion fiber being easy to positioning, leads to
It crosses and three locating rings is set on scattering end, using the position relationship of three locating rings, the Position Approximate at scattering end can be extrapolated,
To realize the positioning at scattering end, the positioning particularly suitable for the longer scattering end of length.
Description of the drawings
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.
Specific implementation mode
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 describes.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, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 is please referred to, the preferred embodiment of the invention provides a kind of dispersion fiber being easy to positioning, includes Transmission Fibers
1 and the scattering end 2 positioned at Transmission Fibers front end, scattering set on end 2, there are three locating ring 3, two of which is located at the two of scattering end 2
Head, another is located at the middle part at scattering end 2.Disperse end 2 is that the fibre core of covering and coat is removed in the front end of Transmission Fibers 1.
Locating ring 3 is provided with tapered slope 4 on the side of the front end far from scattering end 2.By the way that tapered slope 4 is arranged,
It can be according to the direction of tapered slope 4, to judge to scatter the trend at end 2 and position the specific location at scattering end 2.
Scattering is arranged with plastotype sleeve 5 flexible on end 2, and plastotype sleeve 5 is made of polymethyl methacrylate.Poly- methyl
Methyl acrylate is a kind of high material, and the laser in Transmission Fibers 1 can be facilitated to appear.Plastotype sleeve 5 flexible will not be too
The bending at big limitation scattering end 2 can provide certain deformation limitation and reset function for scattering end 2, avoid because scattering end
It is too soft and deform serious.The direction axially outside of plastotype sleeve 5 offers a plurality of guide groove 6, guide groove 6 and plastotype sleeve
5 axial direction is perpendicular.The setting of guide groove 6 can help to scatter end 2 along being provided with the curving of guide groove 6, advancing, and be convenient for
The control for scattering 2 direction of advance of end, desired position is sent to convenient for that will scatter end 2.
The present invention provides a kind of dispersion fiber being easy to positioning, by the way that three locating rings 3 are arranged on scattering end 2, utilizes
The position relationship of three locating rings 3 can extrapolate the Position Approximate at scattering end 2, to realize the positioning at scattering end 2, be particularly suitable for
Positioning in the longer scattering end 2 of length.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, all answer by the change or replacement that can be readily occurred in
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of the claims
It is accurate.
