Portion is socketed with fixing seat, runs through at left and right sides of the bottom of the fixing seat and is equipped with card slot, the bottom of the fixing seat is welded with
Spring, the bottom of the spring are welded with U-shaped needle stand, and the inner cavity of the U-shaped needle stand and the outer wall of needle core are slidably socketed, the U
Fixture block, the top of the fixture block and the inner cavity grafting of card slot are welded at left and right sides of the top of type needle stand.
Preferably, the intracavity bottom of the needle handle is equipped with sample storage chamber, and sample storage chamber is connected to the top of needle core.
Preferably, the tip sidewall of the triangular pyramid type needle point is equipped with several apertures being axially distributed.
Preferably, the outer wall of the fixing seat is equipped with external screw thread.
Preferably, the inner wall of the U-shaped needle stand is equipped with heating layer.
Compared with prior art, the utility model has the beneficial effects that the utility model by U-shaped needle stand by resistance simultaneously
Upward spring is observed by graduation mark so that being fixed in spring contraction and fixture block insertion card slot and is pierced into situation, control
Paracentesis depth controls the puncture speed of needle core during compressed spring, so that controllable, mitigation patient's puncture pain is punctured,
Easy to use, simple operations are completed to puncture, triangular pyramid type needle point sampling convenience, and through-hole can make marrow blood preferably around more
It dissipates, different directions diffusion around can be realized from without adjusting puncture needle direction, reduce marrow blood clotting risk.
Detailed description of the invention
In order to illustrate more clearly of the technical solution of the utility model embodiment, make required for being described below to embodiment
Attached drawing is briefly described, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention,

Other attached drawings.
FIG. 1 is a schematic structural view of the utility model.
In attached drawing, parts list represented by the reference numerals are as follows:
1- needle core, 2- needle handle, 3- graduation mark, 4- triangular pyramid type needle point, 5- through-hole, 6- fixing seat, 7- card slot, 8- spring,
9-U type needle stand, 10- fixture block.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of porous autologous bone marrow transplantation puncture needle, including
Needle core 1, the top of needle core 1 are socketed with needle handle 2, and graduation mark 3 is printed on the right side of the outer wall of needle core 1, and the bottom of needle core 1 is equipped with trigone
Tapered needle point 4, the outer wall bottom front and rear sides of needle core 1 are run through equipped with through-hole 5, and the outer wall top of needle core 1 is socketed with fixing seat
6, through card slot 7 is equipped with, the bottom of fixing seat 6 is welded with spring 8, the bottom weldering of spring 8 for the bottom left and right sides of fixing seat 6
It is connected to U-shaped needle stand 9, the inner cavity of U-shaped needle stand 9 and the outer wall of needle core 1 are slidably socketed, and are welded at left and right sides of the top of U-shaped needle stand 9
