Abstract
The utility model relates to bone puncture needles, in particular to a triangular pyramid type bone puncture needle. The triangular pyramid type bone puncture needle comprises a needle core, a needle sleeve and a handle, a rotating ring is arranged at the connecting position of the handle and the needle sleeve, the needle core is connected in the needle sleeve in a sleeved mode, a puncture head in a triangular pyramid shape is arranged at the front end of the needle sleeve, a side hole is formed in one side wall of the needle sleeve behind the puncture head, a needle core hole corresponding to the side hole is formed in the side wall of the needle core, and a needle hole is formed in the most front end of the puncture head. The puncture head is made to be in a triangular pyramid shape, and is disinfected and treated, the needle does not easily slide when drilled into the bone, strength can be better applied, and more labor is saved. In addition, the side hole is formed in one side wall of the needle sleeve, the corresponding needle core hole is formed in the upper side face of the needle core, the needle hole is prevented from being blocked, and in the sampling process, the better permeability is achieved.
Description
Technical field
This utility model relates to a kind of bone puncture needle, relates in particular to a kind of triangular pyramid type bone puncture needle.
Background technology
In the time that bone punctures, bone puncture needle is as the effective tool piercing in bone, but present bone puncture needle is all a sharp design, is encountering harder position like this, often easily skids and does not make power.In addition, bone puncture is that present medullo-puncture needle only has a pin hole, is very easily blocked by bone fragments in order to extract the bone marrow in bone, and the success rate of bone puncture is reduced greatly.
Summary of the invention
The purpose of this utility model is: the deficiency existing for prior art, provides the triangular pyramid type bone puncture needle that a kind of stability is higher.
For realizing the object of this utility model, be achieved by the following technical solutions:
A kind of triangular pyramid type bone puncture needle, comprise nook closing member, needle guard and handle, junction between described handle and described needle guard is provided with turning collar, described nook closing member is socketed in needle guard, the front end of needle guard is provided with the puncturing head of triangular pyramid shape, one sidewall of puncturing head rear needle guard is provided with side opening, and the sidewall of nook closing member is provided with the nook closing member hole of corresponding side opening, puncturing head have foremost a pin hole.
As preferably, on described handle, be evenly provided with antiskid groove.
As preferably, the diameter in described nook closing member hole is more than or equal to described side opening diameter.
Compared with prior art, the beneficial effects of the utility model are: puncturing head is made to triangular pyramid shape, after disinfection, while piercing in bone, be not easy to skid, can better make strength, and also more laborsaving.In addition, on a sidewall of needle guard, establish side opening, nook closing member upper side arranges corresponding nook closing member hole, and the anti-pin hole that blocks has better permeability in the time of sampling.
Brief description of the drawings
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the structural representation of this utility model puncturing head.
Detailed description of the invention
1-2 makes a detailed explanation detailed description of the invention of the present utility model with reference to the accompanying drawings below.
Embodiment
A kind of triangular pyramid type bone puncture needle, comprise nook closing member 1, needle guard 2 and handle 3, junction between described handle 3 and described needle guard 2 is provided with turning collar 4, described nook closing member 1 is socketed in needle guard 2, it is characterized in that, the front end of needle guard 2 is provided with the puncturing head 5 of triangular pyramid shape, one sidewall of puncturing head 5 rear needle guards 2 is provided with side opening 6, the sidewall of nook closing member 1 is provided with the nook closing member hole 9 of corresponding side opening, puncturing head 5 have foremost a pin hole 7, on described handle 3, be evenly provided with antiskid groove 8.
In use, nook closing member 1 is inserted in needle guard 2, puncturing head 5 exposes completely from needle guard 2, then rotates nook closing member 1 nook closing member hole 9 and side opening 6 are overlapped, and turns afterwards between tight turning collar 4 handles 3 and needle guard 2 and is fastenedly connected.In operating process, the puncturing head 5 of triangular pyramid shape coordinates the head of nook closing member 1 to enter surface of bone, and how complicated no matter the configuration of surface of bone has, while piercing, can there be certain laminating in the outside of triangular pyramid shape, thereby uses certain strength, operates than being easier to.Meanwhile, the side opening 6 on the wall of needle guard 2, increases the permeability in when sampling, and what make that bone marrow is more prone to is drawn out of, and does not affect especially operation in the time that front end pin hole 7 is blocked, and the success rate of bone puncture is improved greatly.
Claims (3)
