Abstract
The utility model relates to a medical laser internal radiation light conducting needle, which is characterized in that the front end of a needle handle is fixed with a needle head; the back end of the needle handle is fixed with a soft tube; the back part of the soft tube is provided with a soft tube joint which is communicated with the inner chamber of the soft tube and a spare connecting mouth; a needle pin and a metal plug are inserted in the soft tube joint; a closed pin cap is inserted on the spare connecting mouth; a pressure reducing hole is arranged on the wall of the closed pin cap; light conducting fiber is positioned in the communicating inner chamber of the needle head, the needle handle, the soft tube, the needle pin and the metal plug. The utility model adopts integration structure, having the advantages of simple operation and less chance of cross infection. The utility model can treat cardiovascular diseases with the laser radiation of optical fiber.
Description
This utility model relates to a kind of medical importing syringe needle.
In the prior art, use the importing syringe needle that optical fibers is imported to cause and use laser irradiation in the vein then, can treat the cardiovascular diseases.Generally be to thrust in the vein blood vessel with thicker remaining needle earlier, reuse left index finger and thumb are fixed trocar sheath, slowly outwards nook closing member are withdrawed from right hand forefinger and thumb.After nook closing member withdraws from vein, do not withdraw from as yet before the trocar sheath, be pressed in the left hand thumb above the skin of trocar sheath apical position, suitably firmly,, retaining outwards bleeds by trocar sheath during nook closing member in case going out to puncture.After nook closing member withdraws from, import laser needle, connect optical fibers by trocar sheath.This importing syringe needle mainly relies on operator's proficiency level, and remaining needle is very thick during puncture, and it is very painful that patient feels.Optical fibers withdraws from the back at nook closing member and imports, troublesome poeration, and the possibility of superinfection is arranged.
The purpose of this utility model is to provide a kind of can disposablely penetrate the integrated medical laser internal radiation of venous light guide needle.
The technical solution of the utility model is: the centre has the front end of the needle handle of cavity to be fixed with the leaded light syringe needle, the rear end of needle handle is fixed with flexible pipe, described flexible pipe rear portion is provided with hose coupling and the spare interface with the flexible pipe intracavity inter-connection, be inserted with pintle in the described hose coupling, the middle part of pintle is provided with metallic plug, be inserted with sealing bolt medicated cap on the described spare interface, have vent on the wall of this sealing bolt medicated cap, optical fibers is arranged in the communication with cavity of syringe needle, needle handle, flexible pipe, pintle, metallic plug.
This utility model compared with prior art has following advantage:
(1). the utlity model has integrated combinative structure, can be behind vascular puncture, directly carrying out laser irradiation, simple to operate, cross infection can not appear.
(2). do not adopt remaining needle, optical fibers directly is placed in the syringe needle, and it is easy to thrust blood vessel, patient's no pain.
(3). flexible pipe can adopt transparent plastic to make, and can see blood back during operation, makes that operation is more accurate.
(4). spare interface can be used as the usefulness of laser irradiation infusion treatment simultaneously, the hardship that can exempt the secondary acupuncture treatment; Also can inwardly inject an amount of normal saline by the syringe that is connected on this spare interface to when not seeing blood back after the minute blood vessel puncture, outwards sucking-off more then, see blood back then certainly syringe needle in vein.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing is structure master's cutaway view of the present utility model; Wherein:
[1]. the syringe needle pillar; [2]. syringe needle; [3]. optical fibers; [4]. needle handle; [5]. flexible pipe; [6]. hose coupling; [7]. pintle; [8]. metallic plug; [9]. spare interface; [10] sealing bolt medicated cap; [11]. vent.
Embodiment: referring to accompanying drawing, the centre has the front end of the needle handle [4] of cavity to be fixed with leaded light syringe needle [2], the rear end of needle handle [4] is fixed with flexible pipe [5], be inserted with pintle [7] in the hose coupling [6] at described flexible pipe [5] rear portion, the middle part of pintle [7] is provided with metallic plug [8], described flexible pipe [5] rear portion also is provided with the spare interface [9] with flexible pipe [5] intracavity inter-connection, be inserted with sealing bolt medicated cap [10] on the described spare interface [9], have vent [11] on the wall of this sealing bolt medicated cap [10], optical fibers [3] is positioned at syringe needle [2], needle handle [4], flexible pipe [5], pintle [7], in the communication with cavity of metallic plug [8].Described vent [11] is positioned at the place, end of spare interface [9].Beginning is when vascular puncture, and described vent [11] is exposed in the air, can see blood back when puncture, simultaneously by outwards aerofluxus of vent [11].After puncture finishes, will seal bolt medicated cap [10] and firmly insert in spare interface [9] inner chamber, make vent [11] enter in the spare interface [9], guarantee the sterile working.In the accompanying drawings, hose coupling [6] inner chamber at flexible pipe [5] rear portion is taper, and outer wall is inserted in the inner chamber of described hose coupling [6] with the pintle [7] that the inner chamber of described hose coupling [6] matches.During use, press solidly vein with the left hand thumb, the right hand is held leaded light needle handle [4] (needle slope upwards) makes syringe needle [2] become 20 degree angles with skin, and percutaneous thrusts in the blood vessel along the vein trend then, and the appropriate depth of moving under water.After seeing that blood back flows into light guide needle flexible pipe [5], unclamp tourniquet, hold with left hand and take the photograph pincers and hose coupling [6] root is vised (suitably firmly), the right hand is held pintle [7] top, suitably firmly it is pushed hose coupling [6] bottom, make optical fibers [3] front end exceed syringe needle [2] certain-length.Then, with metallic plug [8] with treat after used lasing light emitter docks.On leaded light syringe needle [2], be with the syringe needle pillar [1] when detecting luminous power in addition,, can pass through spare interface [9] and be connected with infusion set if in treatment, need in blood vessel, infuse.
