Abstract
A kind of positioning application the invention discloses copper tantalum alloy and its on optical dynamic therapy optical fiber, it is related to medical instruments field, for prior art fibre scattering end by the use of copper or aluminium as less obvious when being positioned at CT scan, it is not easy to be accurately positioned, and acid or alkali of the aluminum easily with human body chemically react, it is unfavorable for the technical problem treated and safeguarded, using a kind of copper tantalum alloy, the copper tantalum alloy is made up of the raw material of following mass percent：Tantalum 30~50%, surplus are copper and inevitable impurity, in impurity：Iron≤0.20%, zinc≤0.20%, aluminium≤3%, nickel≤0.5%, tin≤0.4%, the alloy is arranged on optical dynamic therapy optical fiber original copper or aluminium instead of as fiber orientation point using copper tantalum alloy as anchor point, the present invention, reproduced image resolution of the anchor point in CT scan is not only increased, more solves the problems, such as to be unfavorable for treating and safeguard because chemical reaction occurs for aluminum and human body acid, alkali.
Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of copper tantalum alloy and its determine on optical dynamic therapy optical fiber
Position application.
Background technology
In the medicine equipment for combining photosensitive drug treatment tumour, dispersion fiber is commonly used, its 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
Photosensitive drug is irradiated to, excites photosensitive drug to produce drug effect, reaches the purpose for the treatment of tumour.Currently used dispersion fiber is main
It is divided into two kinds, one kind is post（Bar）Shape usually requires optical fiber extending into inside of human body in addition, one kind is point-like, during treatment, to be real
To the positioning at scattering end during existing CT scan, the both ends for scattering end are respectively equipped with anchor point, Chinese Patent Application No.：
" a kind of dispersion fiber " disclosed in CN201220732021.9 discloses the patent by the use of copper or aluminum as scattering end anchor point,
Due to copper and aluminium in CT scan it is less obvious, be not easy to be accurately positioned, plus this kind of material easily with human body acid or alkali send out
Biochemical reaction, it is unfavorable for treating and safeguards.
The content of the invention
The present invention provides a kind of copper tantalum alloy and its positioning application on optical dynamic therapy optical fiber, to solve existing skill
Art fibre scattering end is not easy to be accurately positioned, and aluminum is easy by the use of copper or aluminium as less obvious when being positioned at CT scan
Chemically reacted with the acid or alkali of human body, be unfavorable for the technical problem treated and safeguarded.
To solve the above problems, the present invention adopts the following technical scheme that realization：
A kind of copper tantalum alloy, it is characterised in that：The copper tantalum alloy is made up of the raw material of following mass percent：Tantalum 30
~50%, surplus is copper and inevitable impurity, in impurity：Iron≤0.20%, zinc≤0.20%, aluminium≤3%, nickel≤
0.5%, tin≤0.4%.
If the present invention considers the individually high cost caused by tantalum material as anchor point meeting, and only by the use of copper or aluminium as
The problems such as anchor point then causes CT scan unintelligible compromise uses copper tantalum alloy, had not only solved processing problems but also had reduced cost.
A kind of positioning application of copper tantalum alloy on optical dynamic therapy optical fiber, it is characterised in that：It is provided with the optical fiber
Above-mentioned copper tantalum alloy.
Preferably, the copper tantalum alloy is annular, and the annulus is fixed on the optical fiber.
Further, one section of scattering section scraped except covering and coat, the scattering section both ends are provided with the optical fiber
It is fixed with the annulus.
The present invention instead of original copper or aluminium as fiber orientation point using copper tantalum alloy, not only increases anchor point and exists
Reproduced image resolution during CT scan, more solve due to aluminum and human body acid, alkali occur chemical reaction and be unfavorable for treatment and
The problem of safeguarding.
Brief description of the drawings
Fig. 1 is example structure schematic diagram provided by the invention.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached in the embodiment of the present invention
Figure, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is the present invention
Part of the embodiment, rather than whole embodiments.The embodiments of the invention being generally described and illustrated herein in the accompanying drawings
The scope for being not intended to limit claimed invention is described in detail, but is merely representative of the selected embodiment of the present invention.Base
Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its
His embodiment, belongs to the scope of protection of the invention.
Because tantalum has good stability and machinability in medical field using relatively broad, but its price is aluminium
Hundreds of times, some be not use that is very important, by the use of pure tantalum material as the medical field of parts, must can reducing tantalum
Amount can is greatly lowered the cost of medicine equipment, therefore we have studied a kind of copper tantalum alloy, the copper tantalum alloy by with
The raw material composition of lower mass percent：Tantalum 30~50%, surplus are copper and inevitable impurity, in impurity：Iron≤
0.20%, zinc≤0.20%, aluminium≤3%, nickel≤0.5%, tin≤0.4%, this kind of alloy not only remain it is good can
Processability, the dosage of tantalum is also drastically reduce the area, also improve the using effect in CT scan image.
Embodiment one
Raw material composition by mass percentage：Tantalum 30%, surplus are copper and inevitable impurity, in impurity：Iron≤
0.20%, zinc≤0.20%, aluminium≤3%, nickel≤0.5%, tin≤0.4%, cross section is made as 1 × 0.5 milli in alloy
Wire and the identical cross section material of rice are respectively that aluminium, the wire while be put into CT Scanner of copper scan, discovery copper
The image of tantalum alloy is substantially than aluminium or the image definition of copper.
Embodiment two
As shown in figure 1, copper tantalum alloy to be made to the anchor point 4 of annular, anchor point 4, which is arranged on, to be scraped except covering 2 and applies
Coating 3 is left behind in the Transmission Fibers of fibre core 1, and the Transmission Fibers other end is connected with connector 5.The optical fiber positioned with copper tantalum alloy
It is obvious more clear and legible than the anchor point individually made with copper product or aluminum in CT scan image.
If the present invention considers the individually high cost caused by tantalum material as anchor point meeting, and only by the use of copper or aluminium as
The problems such as anchor point then causes CT scan unintelligible compromise uses copper tantalum alloy, had not only solved processing problems but also had reduced cost；
Original copper or aluminium instead of as fiber orientation point using copper tantalum alloy, not only increase imaging of the anchor point in CT scan
Definition, more solve the problems, such as to be unfavorable for treating and safeguard because chemical reaction occurs for aluminum and human body acid, alkali.
