With being fixed on human skin, puncture needle can not be removed from soft material.
Utility model content
In order to solve existing problem above, the utility model provides a kind of puncture needle, which can dismantle, will be soft
After body material imports human body, it may be implemented to remove puncture needle from soft material.The utility model specific technical solution is as follows:
The utility model provides a kind of puncture needle, which includes the first pedestal and the second pedestal, on the first pedestal
It is vertical equipped with first through hole and the first syringe needle be connected to first through hole, vertically equipped with the second through-hole and with second on the second pedestal
It through-hole connection and passes through first through hole and protrudes into the second syringe needle in the first syringe needle, on the circumferential side wall of the first syringe needle and the second syringe needle
Offer the opening passed through for soft material, the tops and bottom end of two openings respectively with the first syringe needle 4 or the second syringe needle
Top and bottom end are located at same level, and the extended line positioned at Opening length direction is offered on the first pedestal and the second pedestal
On notch.
Further to improve, the second pedestal upper surface is vertically equipped with protrusion, and the lower surface of the first pedestal is symmetrically arranged with two
For the groove that protrusion protrudes into, when protrusion is inserted in one of groove, two notches are corresponding up and down.
Further to improve, the sum of height of the length of the first syringe needle and the first pedestal is equal to the length of the second syringe needle.
The beneficial effects of the utility model are as follows: puncture needle provided by the utility model can be dismantled, by soft material
After being implanted into the patient, realization takes off puncture needle from soft material.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the puncture needle of embodiment 1；
Fig. 2 is enlarged drawing at Figure 1A；
Fig. 3 is the partial sectional view of the puncture needle of embodiment 2.
Specific embodiment
The utility model is described in further detail with following embodiment with reference to the accompanying drawing, in order to express clearly, this
Each component has carried out corresponding scaling in the attached drawing that utility model provides.
Embodiment 1
Embodiment 1 provides a kind of puncture needle, and as depicted in figs. 1 and 2, which includes the first pedestal 1 and the second base
Seat 2, the first syringe needle 4 for being vertically equipped with first through hole 3 on the first pedestal 1 and be connected to first through hole 3, on the second pedestal 2 vertically
It is connected to equipped with the second through-hole 5 and with the second through-hole 5 and passes through first through hole 3 and protrude into the second syringe needle 6 in the first syringe needle 4, first
Offer the opening 8 passed through for soft material 7 on the circumferential side wall of syringe needle 4 and the second syringe needle 6, the top of two openings 8 and
Bottom end is located at same level, the first pedestal 1 and the second pedestal 2 with the top and bottom end of the first syringe needle 4 or the second syringe needle 6 respectively
On offer the notch 9 being located on the extended line of 8 length directions of opening, wherein the length of the first syringe needle 4 and the first pedestal 1
The sum of height be equal to the length of the second syringe needle 6.
Wherein, the first syringe needle and the second syringe needle are respectively perpendicular on the first pedestal and the second pedestal, and fixed form can wrap
It includes but is not limited to be integrally formed and be clamped, soft material includes but is not limited to electrode wires, two notches difference first through hole and the
The connection of two through-holes；The utility model with the above arrangement, can by soft material be implanted into human body after, the first pedestal of relative rotation
With the position of the second pedestal, so that puncture needle be removed from soft material；Working principle: in use, rotation the first pedestal and
Second pedestal makes two notch alignment, is connected to due to being open with notch, two openings are also aligned, at this time by soft material
It is placed in the first syringe needle and the second pedestal that (soft material can also be straight from the second through-hole of the second pedestal by notch and opening
Connect and penetrate in the second syringe needle), then the first pedestal of relative rotation and the second pedestal, so that two notches is staggered, i.e., soft material is placed
, at this time can be with inserting needle in the space formed by the first syringe needle and the second syringe needle, when inserting needle finishes, soft material has been implanted into human body,
The first pedestal of relative rotation and the second pedestal again make two notch alignment, and also the same alignment of two openings at this time can be in software
The opening and notch for being aligned puncture needle by two in the case where material implantation human body are separated from soft material, then
Soft material can be fixed on by human body surface using clinically used method, the utility model is not specifically limited at this.
Embodiment 2
Embodiment 2 provides a kind of puncture needle, difference from example 1 is that, as shown in figure 3, on the second pedestal 2
Surface is vertically equipped with protrusion 10, and the lower surface of the first pedestal 1 is symmetrically arranged with two grooves 11 protruded into for protrusion 10, when protrusion 10
When being inserted in one of groove 11, two about 9 notches are corresponding.
Wherein, protrusion and the connection type of the second pedestal include but is not limited to weld and be integrally formed, and two grooves surround
The axle center of first through hole is symmetrical arranged；The utility model fixes the first pedestal and the second pedestal with the above arrangement, can play
The effect of position, so that more convenient be put into or take out the first syringe needle by soft material in staff；Working principle: first by
One pedestal pulls out upwards makes protrusion be detached from original groove, at this time by the first pedestal relative to the second pedestal around the through-hole of the second pedestal
180 ° of center axis rotation, be pressed downward the first pedestal at this time, make protrusion be inserted into another groove in, fixation can be realized.
The utility model is not limited to above-mentioned preferred forms, anyone can obtain under the enlightenment of the utility model
Other various forms of products, however, make any variation in its shape or structure, it is all that there is same as the present application or phase
Approximate technical solution, all falls within the protection scope of the utility model.
