Description
Technical Field
The utility model relates to a clinical operation equipment field specifically is a novel lumbar puncture needle.
Background
Lumbar puncture is a commonly used clinical operation. Can be used for diagnosing various inflammatory diseases of central nervous system, vascular diseases, spinal cord diseases, intracranial space occupying diseases, nervous system diseases with unknown diagnosis, pneumoencephalography and spinal canal radiography, etc. Can also be used for treating central nervous system diseases by discharging liquid and injecting medicine due to high cerebrospinal fluid pressure. The lumbar puncture needle is the main using equipment in the lumbar puncture clinical operation at present.
In the prior art, the lumbar puncture needle is basically connected with a common needle tube and an injector, although the use process is very convenient, in the actual use process, particularly during intrathecal injection, the problems of leakage of liquid medicine, over-quick injection and the like are easily caused due to no assistance. Thereby resulting in an increased rate of surgical failure and adverse health of the patient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel lumbar puncture needle to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a novel lumbar puncture needle, includes puncture needle tubing, is fixed with the syringe seat at puncture needle tubing afterbody, and the cartridge has the puncture needle core rather than sliding connection in puncture needle tubing, is fixed with the syringe seat at puncture needle core afterbody, syringe seat afterbody has external screw thread mouth, and external screw thread mouth and puncture needle inside are hollow structure, have the external screw thread on external screw thread mouth outer wall, are equipped with the recess on puncture needle tubing's outer wall, be equipped with protruding mark on the puncture needle core outer wall, and puncture needle tubing and puncture needle core pass through recess and protruding looks coupling.
The puncture needle tube and the puncture needle core are both cylindrical, and the needle tube seat and the needle core seat are both conical with a forward closing-up.
As the preferred scheme of the utility model: the top ends of the puncture needle tube and the puncture needle core are provided with inclined planes, the direction of the upper inclined plane of the puncture needle tube is consistent with the direction of the groove, and the direction of the upper inclined plane of the puncture needle core is consistent with the direction of the convex mark.
Compared with the prior art, the beneficial effects of the utility model are that: this device improves on original pjncture needle basis, through the setting of external screw thread mouth, can connect the extension line and the injection in the external trace implementation pump sheath, when carrying out the injection in the sheath, does not need the art person to hold up the syringe for a long time, avoids artificial injection syringe to cause injection speed unstability, shortcomings such as revealing easily.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-a puncture needle tube, 2-a needle tube seat, 3-an external threaded port, 4-a puncture needle core and 5-a needle core seat.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example 1:
please refer to fig. 1, in the embodiment of the present invention, a novel lumbar puncture needle comprises a puncture needle tube 1, a needle tube seat 2 is fixed at the tail of the puncture needle tube 1, a puncture needle core 4 slidably connected to the puncture needle tube 1 is inserted in the puncture needle tube 1, a needle core seat 5 is fixed at the tail of the puncture needle core 4, an external thread port 3 is provided at the tail of the needle tube seat 2, the external thread port 3 and the puncture needle tube 1 are both hollow structures, an external thread is provided on the outer wall of the external thread port 3, a groove is provided on the outer wall of the puncture needle tube 1, a protruding mark is provided on the outer wall of the puncture needle core 4, the puncture needle tube 1 and the puncture needle core 4 are coupled through a groove and a protrusion, and the connection stability between the puncture needle tube 1 and the puncture needle core 4 is ensured through the protrusion and the groove.
