Abstract

The utility model relates to an intervertebral disc puncture syringe needle, its characterized in that: it includes a needle file a fastening connection hollow syringe needle on the needle file, the nook closing member of planting in the syringe needle, the needle point of syringe needle sets up to the scarf the syringe needle is close to set up two limiting plates on the pipe wall of the one end of needle point relatively, each the limiting plate is close to the one end of needle point is the rectangle, keeps away from the one end of needle point is the triangle -shaped of convergent. The utility model discloses owing to setting up two limiting plates on the pipe wall that is close to the one end of needle point at the syringe needle relatively, be provided with the scale mark on the surface of syringe needle, consequently can understand the degree of depth of puncture immediately and control, reach quick arrival target spot, reduce the purpose of the perspective radiation of relapse to human body injury and intervertebral disc damage. The utility model discloses a consequently the needle file is convenient for hold between the fingers when using and is held owing to be hollow prismatic structure, and hollow structure can be used to be connected with the syringe simultaneously, carries out contrast medium, cytokine injection or transplants the cell.

Description

A kind of intervertebral disc puncture entry needle
Technical field
This utility model relates to a kind of intervertebral disc puncture entry needle, belongs to medical instruments field.
Background technology
Discography is the conventional detection methods of degenerative disc disease, and when carrying out discography, needs first puncture to intervertebral disc, then to injection of contrast medium in intervertebral disc.And need to inject cytokine or transplanted cells in the intervertebral disc punctured to treat degenerative disc disease.But intervertebral disc puncture can cause certain damage to intervertebral disc and can aggravate intervertebral disc degeneration.During intervertebral disc puncture, puncture doctor needs first to position under fluoroscopy, then after local anesthesia under guide of fluoroscopy, puncture needle enters vertebral pulp central authorities through after skin, muscle layer and outer layer fiber ring successively.And existing intervertebral disc puncture pin is not owing to having the structure controlling to thrust the degree of depth, therefore cause in piercing process and need repeatedly to have an X-rayed with repeated localised puncture and then determine paracentesis depth, the intervertebral disk injury of dark meeting making patients if punctured, punctured shallow, and do not arrive target spot, perspective also can make doctor and patient's raying amount increase for a long time simultaneously.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the controlled intervertebral disc puncture entry needle of a kind of paracentesis depth.
For achieving the above object, this utility model takes following technical scheme: a kind of intervertebral disc puncture entry needle, is characterized in that: it comprises a needle stand, and described needle stand is fastenedly connected the entry needle of a hollow; To plant in described entry needle a nook closing member; The needle point of described entry needle is set to oblique section, is oppositely arranged two limiting plates at described entry needle on the tube wall of one end of described needle point; Limiting plate described in each is rectangular near one end of described needle point, and the one end away from described needle point is the triangle of convergent.
Described needle stand is the prism structure of hollow and is communicated with described entry needle.
The surface of the described entry needle between described limiting plate and described needle point is provided with the graduation mark observing paracentesis depth.
Described limiting plate offers cutting edge; Described limiting plate is arranged on apart from described tip position 3.2 ~ 9.2mm place.
The diameter of described entry needle is 0.6 ~ 1.6mm.
The thickness of described limiting plate is 0.3mm.
This utility model is owing to taking above technical scheme, it has the following advantages: 1, this utility model owing to being oppositely arranged two limiting plates at entry needle on the tube wall of one end of needle point, the surface of entry needle is provided with graduation mark, therefore immediately can understand the degree of depth of puncture and be controlled, reach and arrive target spot fast, reduce the object of Radiation On Human body injury and the intervertebral disk injury repeatedly had an X-rayed.2, limiting plate of the present utility model is rectangular near one end of needle point, and the one end away from needle point is the leg-of-mutton streamlined structure of convergent, therefore decreases the friction to disc tissue and damage when puncturing.3, needle stand of the present utility model is due to the prism structure for hollow, is therefore convenient in use grip, and hollow structure can be used for being connected with syringe simultaneously, carries out contrast agent, cytokine injections or transplanted cells.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in detail.
As shown in Figure 1, this utility model comprises a needle stand 1, and needle stand 1 is fastenedly connected the entry needle 2 of a hollow.Plant in entry needle 2 nook closing member 3, nook closing member 3 is injected in intervertebral disc after preventing in piercing process the soft tissues such as muscle to enter needle tubing again.The needle point 21 of entry needle 2 is set to oblique section, for improving puncture efficiency.On the tube wall of one end of needle point 21, two limiting plates 4 are oppositely arranged at entry needle 2, each limiting plate 4 is rectangular near one end of needle point 21, one end away from needle point 21 is the triangle of convergent, and then form streamline structure, limiting plate 4 can not through fine and close outside fiber ring for one end rectangular when puncturing, guarantee can not puncture position excessively dark, one end triangular in shape is then for the ease of the withdraw of the needle.
In above-described embodiment, needle stand 1 is the prism structure of hollow and is communicated with entry needle 2, grips for being convenient in use, and hollow structure can be used for being connected with syringe simultaneously, carries out contrast agent, cytokine injections or transplanted cells.
In above-described embodiment, limiting plate 4 offers cutting edge, and limiting plate 4 can be arranged on 3.2 ~ 9.2mm place, position of distance needle point 21.
In above-described embodiment, the diameter of entry needle 2 is 0.6 ~ 1.6mm.
In above-described embodiment, the thickness of limiting plate 4 is 0.3mm.
In above-described embodiment, the surface of the entry needle 2 between limiting plate 4 and needle point 21 is provided with graduation mark, is convenient to the degree of depth that patient understands puncture immediately.
Intervertebral disc place epidermis operationally, is first expanded, is then inserted in patient disc under perspective environment by this device by this utility model a little, and confirms insertion depth according to the graduation mark on entry needle 2 surface.If operate wrong when being inserted beyond preset value, owing to being provided with limiting plate 4, the rectangular configuration of limiting plate 4 front end can not through fine and close outside fiber ring, and therefore there will not be puncture aggravates the problem of intervertebral disc degeneration deeply.After puncture terminates, extract nook closing member 3 out, then by the contrast agent of syringe to the transplanted cells of injection for curing in entry needle 2, cytoskeleton, cytokine or diagnosis, and then complete discography.
The various embodiments described above are only for illustration of this utility model; wherein the structure, connected mode etc. of each parts all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
