Abstract
The utility model relates to quick liver puncture apparatus. The utility model is provided with a puncture needle head in which a steel needle core is arranged and an injector. The utility model is characterized in that the puncture needle head is directly arranged on the injector, the side face of a needle pin of the injector is equally provided with a plurality of cut grooves at intervals, and a back wing of a tube body of the injector is movably provided with a positioning latch which can be clamped in the cut grooves. The utility model has the advantages of simple and reliable structure and convenient, quick and accurate operation. One person can completed the process of liver puncture.
Description
This utility model belongs to the puncture instrument technical field that is used to diagnose sampling.
General liver puncture utensil has a trocar at present, and the steel wire stylet piston is housed in the syringe needle, and piercing needle is connected on 10ml or the 20ml syringe by a rubber tube.The phenomenon of leaking gas often appears when using that rubber tube two ends connect imprecision and in this perforator, the fine rule of the rubber tube and the rubber tube that is fastened also can be because of the multiple high temp sterilization fracture of wearing out, must two people operate when particularly working, use inconvenience, cooperate difficulty big, cause error easily, bring unnecessary misery to patient.
The purpose of this utility model provides a kind of liver puncture device reliable, easy to operate, that a people can finish the work fast that uses.
This utility model comprises piercing needle and the syringe that steel wire stylet is housed in it equally, its construction features is that piercing needle is directly installed on the syringe, equally be processed with several otch grooves in the side of syringe pintle spacing, on the rear wing of syringe body, be movably installed with a location door bolt.
This utility model is compared with existing liver puncture device and is had the following advantages: the one, and simple in structure, use reliable, gas leak phenomenon can not take place, the 2nd, easy to operate, only need a people independently to finish piercing process fast, do not have the combination miss phenomenon, liver is worn routinize, thereby help making liver living tissue's pathological diagnosis, reduce the unnecessary misery of patient.
Fig. 1 is a perspective view of the present utility model,
Fig. 2 is the front view of another embodiment of this utility model.
In the embodiment that Fig. 1 provides, syringe 2 adopts the plastic injector for temporary use of 20ml, on four flanks of the piston pintle 3 of syringe 2, equidistantly distributed otch groove 4, be 5ml, 7.5ml, 10ml, 12.5ml, 15ml, 17.5ml, 20ml place for example, on the different flanks of pintle 3, be processed with 7 groove breach 4 successively altogether at the syringe capacity.Bore an aperture on the rear wing of syringe 2 bodys, be movably installed with the location door bolt 5 of a safety pin formula on the hole, when moving syringe behind the pintle and be in a certain capacity, location door bolt 5 snaps in the otch groove 4 corresponding with this capacity, and pintle 3 can not be moved forward.For improving locating effect, the otch groove 4 on the pintle 3 also has inclination angle forward.Piercing needle 1 is identical with at present general piercing needle, is the trocar of dress steel wire stylet in, is directly installed on the front end of syringe 2.
Among the embodiment that Fig. 2 provides, syringe 2 is permanent glass syringe, and otch groove 4 equidistantly distributes in the same side of pintle 3, and piercing needle 1 is identical with last embodiment with the structure and the installation of location door bolt 5.
