In the percutaneous bone puncture biopsy device, the diameter of the needle core is 2.5-4.5mm, the head at the front end of the needle core is triangular cone-shaped, so that a bone lesion is conveniently punctured, the needle core is of a hollow structure, two ends of the needle core are both open, the inner diameter of the needle core is 1.1-1.2mm, the diameter of the Kirschner wire is 1mm, the front end of the Kirschner wire is also triangular cone-shaped, the tail end of the Kirschner wire is flat, the surface of the Kirschner wire is marked with cm scales.
Compared with the prior art, the utility model discloses a with puncture sleeve pipe anterior segment cavity inner wall design internal thread to possess the cusp and protruding, the sample can form inseparable interlock with sleeve pipe internal thread profile of tooth when rotatory entering focus, the sample is fixed alright take out smoothly. Overcomes the defects that the conventional puncture cannula needs to be punctured for many times and the specimen can not be taken out. And because the surface of the puncture cannula is uniformly marked, the depth position of the trocar can be judged in real time, so that the operation is simple, convenient and safe.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.
Example (b):
referring to fig. 1 to 4, the present embodiment provides a percutaneous bone puncture biopsy device, which includes a kirschner wire 1, a needle core 2 and a percutaneous bone puncture cannula 3, wherein the needle core 2 is sleeved on the kirschner wire 1, a tail portion of the kirschner wire 1 is led out from a tail end of the needle core 2, the percutaneous bone puncture cannula 3 is sleeved on the needle core 2, and the percutaneous bone puncture cannula 3 has a holding portion 4 thereon.
The diameter of the needle core 2 is 2.5, 3.5, 4.5mm, the head of the front end of the needle core 2 is triangular cone-shaped, which is convenient for puncturing bone focus, the tail end of the needle core 2 is provided with a tail handle 5, the needle core 2 is of a hollow structure, both ends are open, the inner diameter is 1.1mm, the diameter of the Kirschner needle 1 is 1mm, the front end of the Kirschner needle 1 is also triangular cone-shaped, the tail end is flat, the surface is marked by CM and divided by mm small lattices, the length of the body part (the length of the front end main body) of the needle core 2 is consistent with the length of the percutaneous bone puncture cannula 3, the front end 3CM is an external tooth screw, during puncturing, the percutaneous bone puncture cannula 3 and the needle core 2 are integrated and smoothly reach the focus surface through a positioning needle, then the needle core 2 is taken out, the percutaneous bone puncture cannula 3 is gradually rotated into the focus according to the focus size and the cannula surface scale, thereby judging the depth of the required sample amount of the focus, after, because the specimen is closely combined with the dentate inner screw at the front end of the percutaneous bone puncture sleeve 3, the specimen is fixed in the percutaneous bone puncture sleeve 3; then the needle core 2 is screwed in along the percutaneous bone puncture cannula 3, and the specimen can be taken out from the cannula.
