Abstract
A special puncture needle for photodynamic therapy is composed of a transparent needle body and a steel core, and features that its tip is closed to form a needle cavity, in which an optical fibre illuminator is arranged. As a result, the laser beam can reach the tumor tissue without attenuation and said illuminator is not directly contacted with the tumor tissue.
Description
1, technical field the present invention is the special-purpose puncture needle of a kind of optical dynamic therapy, belongs to the medical apparatus and instruments manufacture technology field.
2, optical dynamic therapy is used biopsy pin or other similar puncture needles more between the existing tissue of background technology, this puncture needle generally is made up of nook closing member and needle body, during treatment, earlier the puncture needle nook closing member is inserted needle body, then puncture needle is inserted in the tumor tissues, behind the arrival assigned address, extract nook closing member, optical fibers is inserted the puncture needle body, then withdraw from needle body 2-5 centimetre or all withdraw from column lasing light emitter with abundant exposure optical fibers head to arrive therapeutic purposes.Therefore, used smooth power puncture needle nook closing member, needle body separate residues in the puncture needle tumor cell, cause the plantation of tumor cell to be shifted easily, the bore of puncture needle is crossed and thick easily normal taeniae telarum is come unnecessary damage, in addition with this puncture needle processing ease expensive optical fibers that fractures.
3, summary of the invention designs the special-purpose puncture needle of a kind of optical dynamic therapy, to adapt to the needs of light power tumor.The present invention dwindles the sealing of the tip of puncture needle, bore, and makes needle body with transparent hard plastic (all can monitor under B ultrasonic and the CT) and make its transparent optical dynamic therapy that is beneficial to, and during puncture the steel nook closing member is inserted the pin chamber in case puncture needle bending or fracture.Press the present invention that such scheme is realized, the puncture needle bore dwindles and has reduced the damage of puncture needle to normal structure, most advanced and sophisticated sealing can reduce the plantation of tumor cell to greatest extent to be shifted, and transparent needle body has avoided common puncture needle to fibre-optic damage to greatest extent.
4, description of drawings accompanying drawing of the present invention and being described as follows:

1. is now now now existing existing with optical fibers light guide section in the optical fibers column luminous body 10. puncture needle treatments of the present invention in the needle body 9. puncture needle treatments of the present invention of needle point 8. puncture needles of the present invention of nook closing member 7. puncture needles of the present invention of optical fibers light guide 6. puncture needles of the present invention in the puncture needle treatment with optical fibers column luminous body in the puncture needle treatment 5. with the needle point 4. of puncture needle with the nook closing member 3. of puncture needle with the needle body 2. of puncture needle among the figure.
5, the specific embodiment now uses the needle point (3) of puncture needle to communicate with the pin chamber of the puncture needle needle body (1) in Fig. 1 b; In Fig. 1 c, under B ultrasonic or CT guiding, puncture needle is inserted the oncotherapy position, extract nook closing member (2) then; In Fig. 1 d, insert the optical fibers of optical dynamic therapy special use, the optical fibers end has 1-5 centimetre of column luminous body, but owing to now use the puncture needle needle body (1) is steel, opaque, therefore laser can't see through, and have only the corresponding 1-5 of withdrawing from of puncture needle centimetre can be exposed to optical fibers column luminous body (4) in the tumor tissues, thereby the luminous physical ability of column that reaches the optical fibers end is sent the laser of capacity and treated.Because the suppleness of the tumor tissues that is punctured is different with elasticity, therefore being exposed to optical fibers expensive in the tumor tissues is easy to fracture, because the some position of oncotherapy is more, therefore puncture needle nook closing member (2) and optical fibers column luminous body (4) insert repeatedly in tumor tissues and withdraw from, and are easy to cause the plantation of tumor cell to shift.
In Fig. 2 b and Fig. 2 c illustrated embodiment, the special-purpose puncture needle needle body of optical dynamic therapy of the present invention (8) is made with transparent rigid plastics (all can monitor under B ultrasonic and the CT), but its bore is less than now using puncture needle, therefore the damage to normal structure is reduced to minimum level, puncture needle needle point (7) thus sealing makes the pin chamber of puncture needle obtain sealing, the nook closing member of puncture needle (6) just can not directly contact with tumor tissues like this, can not cause the plantation of tumor cell to be shifted even extract nook closing member; In Fig. 1 d, insert optical fibers during treatment, optical fibers column luminous body (9) sends the purpose that the laser irradiation tumor can reach treatment at puncture needle pin intracavity transparent and sealing, causes fibre-optic damage so that fracture thereby avoided optical fibers column luminous body directly to contact with tumor tissues.
Claims (2)
1. the special-purpose puncture needle of optical dynamic therapy is made up of the transparent needle body and steel nook closing member, and the tip portion of puncture needle is what seal.Purpose is that the optical fibers column luminous body of optical dynamic therapy special use can place puncture needle pin intracavity, in the tumor tissues that the arrival light power that the laser that the transparent puncture needle body of one side can make optical fibers column luminous body be sent is decayed is not treated, in the hope of reaching the effect of optical dynamic therapy; Seal puncture needle pin intracavity on the other hand and make optical fibers column luminous body directly not contact tumor tissues, the indirect transfer of minimizing tumor cell that can be the least possible, and can protect optical fibers column luminous body so as not to the damage in addition fracture.
2. the present invention according to claim 1 is characterized in that the special-purpose puncture needle of optical dynamic therapy is a puncture needle transparent, the special use of sealing needle point optical dynamic therapy.
