Further, described crotch is three.
Further, described syringe interface is taper, and the less one end of syringe interface is connected with cannula end, larger
One end be used for be connected with syringe.
Further, the larger one end inwall of described syringe interface has internal thread.
Further, the larger one end inner wall shape of described syringe interface is matched with injector head profile.
Further, it is provided with sealing ring at the larger one end inwall of described syringe interface.
Further, also include angle positioning device, described angle positioning device includes support and is arranged on support
Protractor, the center of described protractor is provided with the Kato that can rotate in the plane of protractor place.
Further, described Kato section is arc groove, is adapted with the sleeve outer of puncture needle.
Further, described protractor is 90 ° of protractors.
Compared with prior art, the utility model has the advantage that and beneficial effect：
Many hook designs on puncture needle core top, increased the firmness after puncture needle positioning, are difficult displacement and come off；With
When, cannula end is provided with Dye Injections device interface, not only can improve the degree of accuracy of dyestuff coloration station moreover it is possible to prevent dyestuff from spilling
Go out；In addition, being additionally provided with the angle positioning device being adapted to puncture needle, improve the accuracy of Needle localization.

Specific embodiment
With reference to the accompanying drawings and detailed description, it is further elucidated with the utility model it should be understood that following specific embodiment party
Formula is merely to illustrate the utility model rather than limits scope of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, the lung puncture pilot pin that the utility model provides is mainly by puncture needle core 1 and sleeve pipe 2
Composition, sleeve pipe 2 is a hollow cylinder, and cannula tip 21 is tapered, and cannula end 22 is provided with syringe interface 3, and puncture needle core 1 is worn
It is located in sleeve pipe 2, pillow top 11 has three crotches 111, the quantity of crotch can be arranged as required to, at least two.
Puncture needle core 1 is contractile to be strapped in sleeve pipe front end, and nook closing member tail end 12 stretches out at the syringe interface 3 of cannula end 22.
Specifically, syringe interface is taper, and its less one end is connected with cannula end, larger one end for
Injector head connects.The larger one end inner wall shape of syringe interface is matched with syringe interface, can be provided with close at inwall
Seal, makes formation between syringe interface and syringe be tightly connected.In order that the connection between syringe interface and syringe
It is difficult to get loose, the larger one end inwall of described syringe interface is additionally provided with internal thread, and accordingly, injector head has outer spiral shell
Line.Syringe interface also can be connected with syringe injection head using the other modes such as snapping connection.
When carrying out preoperative Needle localization, specific operation process is as follows：The hook formation 111 on puncture needle core 1 top is initial
It is contracted in sleeve pipe 2 front end, after determining lesions position, the front end that sleeve pipe 2 is had hook formation 111 penetrates into affected area,
When CT scan confirms that position is accurate, then puncture needle core 1 is advanced or sleeve pipe 2 is retreated, the now hook on puncture needle core 1 top
Shape structure 111 can stretch out sleeve pipe 2, so that hook formation 111 opens（See Fig. 2）, and it is fixed on affected area.In puncture needle core 1
After the completion of fixation, the syringe interface 3 of the injection head of Dye Injections device and sleeve pipe 2 tail end 22 is tightly connected, then by fuel
It is expelled to lesions position along sleeve pipe, complete focus dyeing.As threaded etc..
As Fig. 4, in clinical manipulation, in order to improve the degree of accuracy of the angle when Needle localization is needled into focus, this lung is worn
Thorn pilot pin is additionally provided with an angle positioning device 4, and it is mainly made up of with the protractor 42 being arranged on support 41 support 41, amount
