Embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.

Referring to figs. 1 through Fig. 6, the utility model embodiment provides a kind of organization chip puncture needle, comprise puncture needle member and nook closing member member, puncture needle member comprises puncture needle tubing 12, and puncture needle tubing 12 is hollow needle tube, the rear end connecting needle base 11 of puncture needle tubing 12, the front end of puncture needle tubing 12 is provided with tapered cut 13, the tangent plane of tapered cut 13 can be ellipse, can be also half elliptic as shown in Figure 6, the shape of the similar Luoyang Spade of half elliptic tangent plane;

Nook closing member member comprises nook closing member bar 22, and nook closing member bar 22 is longer than puncture needle member, long 20mm for example, and the rear end connecting needle core print seat 21 of nook closing member bar 22, the front end of nook closing member bar 22 is provided with level and smooth otch 23;

The outer first set pipe 31 that is socketed with of puncture needle tubing 12, the first sleeve pipe 31 is connected and fixed on the front end of needle tubing seat 11, the front end of puncture needle tubing 12 exceeds the front end 5mm of the first sleeve pipe 31, preferably in the first sleeve pipe 31, is provided with first piston 32, and puncture needle tubing 12 is through first piston 32.During punching, the first sleeve pipe 31 works to control puncture needle pipe 12 depth of needle, and 32 pairs of thorn needle tubings 12 of first piston play good fixed action.

Nook closing member bar 22 penetrates puncture needle tubing 12 inside by needle tubing seat 11, level and smooth otch 23 front ends of nook closing member bar 22 are concordant with tapered cut 13 front ends of puncture needle tubing 12, between needle tubing seat 11 and needle core base 21, be provided with the second sleeve pipe 41, the second sleeve pipe 41 is connected and fixed on the rear end of needle tubing seat 11, preferably in the second sleeve pipe 41, be provided with the second piston 42, nook closing member bar 22 is socketed in the second sleeve pipe 41 through the second piston 42, and it is more stable that the second piston 42 makes nook closing member bar 22 penetrate puncture needle tubing 12 inside.
