Abstract
A kind of plastic optic fibre needle used for internal irradiation therapy of vessel is mounted on optic fibre output terminal of the laser therapeutic machine, i.e. the plastic optic fibre (2) is mounted in the core hole of the joint. The two end faces of the optic fibre (2) are semi-shperical lens in shape. The texture of the plastic optic fibre is soft, so it is more convenient to insert directly in the vessel to irradiate. Its external surface has no need of stainless steel protective pipe, so it is not easy to penetrate the vessel. The end of the optic fibre can close the affected portion to a maximum to proceed the laser irradation, so the curative effect is more notable. In addition the structure and productive process are simple, cost is low, so such a disposable medical appratus is easy to spread.
Description
The present invention relates to medical apparatus, particularly Disposable plastical optic fibre needle for radiation in blood vessel a kind of and light combination introducing human body.
At present; the therapeutic medical optical fiber pin of existing intravascular irradiation all adds the cover rustless steel with quartz glass optical fiber and makes; it enters the quartz glass optical fiber part in the human vas; must use the rustless steel sleeve pipe to be protected at skin especially, the laser accunputure head be hard, very easily piercing blood vessel; this just increases medical worker's work difficulty greatly; optical fiber is difficult to dark inserting, and has influenced curative effect, makes the patient very painful when accepting diagnosis and treatment simultaneously.The production technology of quartz glass optical fiber and meticulous stainless steel tube is very complicated, and cost is very high, and the market price is low does not naturally get off.Therefore, in reality was used, medical department was difficult to it as disposable medical appliance, and the back of generally all will sterilizing is reused.If disinfectant measure is not strict slightly, just easily cause patient's cross-fire treatment to infect.
We can provide that a kind of raw material source is wide to the public here, low price, production technology is simple, cost is low, are suitable for promoting making disposablely to use, easily be the therapeutic medical optical fiber pin of novel vascular internal radiation of medical worker and patient's acceptance.
Realize the technical foundation of foregoing invention purpose, mainly substituting tradition with the cheap plastic optical fiber of price uses, the quartz glass optical fiber of fetch long price, optical fiber pin promptly of the present invention are plastic optical fiber to be packed in the core hole of the union joint made from metal or nonmetallic materials constitute.
Very thin plastic optical fiber in the optical fiber pin of the present invention belongs to the non-toxic plastic optical fiber that meets international health care standard-required, can directly insert and carry out irradiation treatment in the blood vessel, and outer surface does not need other suit stainless steel tube protection; Plastic optical fiber material softness is easier to insert operation, and can piercing blood vessel, unlikelyly causes unnecessary misery to the patient; The optical fiber syringe needle can carry out laser irradiation near affected part to greatest extent, and medical effect is more remarkable.The structure of neoteric optical fiber pin and production technology simplify greatly than traditional quartz glass optical fiber pin, and Master Cost also descends significantly, so price naturally can be cheap, thereby make medical institutions be easy to carry out disposable use, have avoided patient's cross infection.
Below in conjunction with accompanying drawing in detail specific embodiments of the present invention is described in detail:
Fig. 1 is a population structure sketch map of the present invention.
The effect of union joint of the present invention (1) is the same with traditional optical fiber pin union joint, is used for being connected with the clamper of laser therapeutical machine fiber-optic output.Because union joint (1) do not contact patient's human body, so can use nonmetallic materials making such as common metal or rigid plastics, pottery, glass.Comparatively economical, practical scheme is to adopt alloy aluminum.Its overall dimensions is identical with the union joint of traditional fiber pin; Its core bore dia then needs the outside dimension preparation according to the plastic optical fiber that is equipped with (2).Used plastic optical fiber (2) often is 0.5 to 0.7 millimeter non-toxic plastic optical fiber for external diameter.The visual clinical needs of its length are determined.It is planar that the both ends of the surface of plastic optical fiber (2) need to make hemisphere face shape optical lens with the hot-working method of routine.Plastic optical fiber (2) is inserted in the core hole of union joint (1), again at core nose end head with nontoxic adhesive (3) with plastic optical fiber (2) cementation.
Claims (2)
1, the medical apparatus, particularly Disposable plastical optic fibre needle for radiation in blood vessel of human body introduced in the combination of a kind of and light, it is characterized in that: it is to be packed in the core hole of the union joint (1) that metal or nonmetallic materials make with plastic optical fiber (2) to constitute.It is planar that plastic optical fiber (2) both ends of the surface are hemisphere face shape optical lens.
2, Disposable plastical optic fibre needle for radiation in blood vessel according to claim 1 is characterized in that plastic optical fiber (2) is inserted in the core hole of union joint (1), uses avirulent adhesion agent (3) with plastic optical fiber (2) cementation at core nose end head again.
