Pricker is hollow metal needle tubing, and puncture needle pedestal is made of soft memory material and both sides are symmetrical fin, puncture needle, puncture needle
Inside after pedestal, drainage tube are connected with end attachment base forms connection cavity.
The utility model has the advantages that
A, needle handle is made of two fins with circular through hole, fixes convenient for suture or skin nail is fixed, prevent puncture needle sliding
It is de-, make to puncture the simple to operate of ommaya capsule, puncture needle fixation is not easy；
B, it is equipped with cylindrical needle cap in the upper surface of puncture needle pedestal, is conducive to hand-held needle handle in this way, hold inserting needle direction, it is quasi-
True puncture drainage；
C, the avoidable manual bending syringe needle of dedicated puncture needle is broken, and using the puncture needle of suitable length, can be reduced
Puncture needle is exposed to the chance infected outside scalp；
D, sustainable row cerebrospinal fluid puncturing drainage, avoids puncturing repeatedly, reduces infection risk；
E, drainage connecting pipe is the common drainage tube of similar transfusion needle, and end attachment base can connect Medical tee joint connector,
Convenient for leaving and taking chemical examination, injection, external drainage bottle, realizes multiple functions, be convenient for puncture and drainage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1 is puncture needle, and 2 be pedestal double-vane, and 3 be cylindrical needle cap, and 4 be drainage tube, and 5 be attachment base, and 21 be double-vane
