[0030] Need to explain, the existing nerve stimulation needle in actual puncture process, doctor is usually according to own experience to grasp the insertion depth of acupuncture needle.Some inexperienced doctors are difficult to control the insertion depth of acupuncture needle.The utility model is slowly inserted into the subcutaneous of patient when being used needle core 11, and sleeve 2 is abutted on the skin of patient, needle seat 1 is slid along the through hole 21 of sleeve 2 at this time.The scale reference mark 141 on needle seat 1 points to the scale mark 22 as the depth of needle core 11 insertion in the subcutaneous of patient, help doctor to master the insertion depth of needle core 11 through the sleeve 2 with scale.Meanwhile nerve stimulation acupuncture needle can also be connected into nerve stimulation instrument, and the target nerve is found through nerve stimulation instrument.

[0031] Among them, in the scheme of the application, the conducting wire 13 is connected to the needle seat 1, and after the conducting wire 13 is connected to the external nerve stimulation instrument, the electrode sends an electric stimulation signal of a specific frequency and intensity to the nerve tissue around the acupoint. This electric stimulation can directly act on the nerve fibers, regulate the excitability of the nerves, promote the release of neurotransmitters, and thus produce a therapeutic effect. It can be used for the treatment of nervous system diseases. Further, since the doctor needs to operate the insertion of the needle core 11 during the electric stimulation treatment, the needle seat 1 needs to be configured as an insulating material structure.

[0032] Further, as shown in Figure 1 、 Figure 2 and Figure 3As shown, the needle seat 1 is in a cylindrical structure, and the outer diameter of the cylindrical structure is the same as the inner diameter of the through hole 21. In this way, the needle seat 1 can only slide along the extension direction of the through hole 21, so that the needle core 11 can be smoothly inserted into the subcutaneous tissue of the patient.

[0033] Further, as shown in Figure 2 and Figure 3 , the needle seat 1 is provided with a limiting track 14 extending along the extension direction of the needle seat 1; the cannula 2 is provided with a limiting groove 23 corresponding to the position of the limiting track 14, the limiting groove 23 penetrates the side wall of the cannula 2, and the limiting groove 23 extends along the extension direction of the cannula 2, and the limiting track 14 is slidingly arranged along the limiting groove 23. Through the limiting groove 23 and the limiting track 14, the needle seat 1 can only slide in a specific direction and angle in the through hole 21, and rotation will not occur. At the same time, the scale reference mark 141 on the needle seat 1 can be aligned with the scale mark 22 on the cannula 2, which facilitates the doctor to grasp the insertion depth of the needle core 11.

[0034] Further, as shown in Figure 2 and Figure 3 , the limiting track 14 is provided with a needle wing 142, the needle wing 142, the limiting track 14 and the needle seat 1 are integrally formed, and the needle wing 142 and the limiting track 14 are both of insulating material structure. The integrally formed structure design can reduce the number of production abrasives and reduce production cost. Configuring the needle wing 142 and the limiting track 14 as insulating material structure can avoid the pulse on the needle core 11 from being conducted to the doctor's fingers, avoiding affecting the diagnosis and treatment effect.

[0035] Further, as shown in Figure 2 and Figure 3 , the scale reference mark 141 is arranged on the limiting track 14. In this embodiment, the scale reference mark 141 is arranged on the limiting track 14, and the scale reference mark 141 is exposed on the outside, which facilitates the doctor to observe the scale mark 22 pointed by the scale reference mark 141 and grasp the insertion depth of the needle core 11.

[0036] Further, as shown in Figure 1 , the conductive wire 13 is provided with a nerve stimulator interface 131 at the end away from the needle seat 1, and the nerve stimulator interface 131 is electrically connected with the needle core 11. Through the nerve stimulator, pulse current is supplied to the needle core 11, realizing the effects of nerve block, nerve diagnosis and surgical navigation.

[0037] Further, as shown in Figure 2 and Figure 3 , the scale marks 22 are arranged along the extension direction of the cannula 2. And the scale marks 22 are arranged along one side or both sides of the limiting groove 23 on the cannula 2. In order to facilitate the doctor to observe the scale mark 22 pointed by the scale reference mark 141 with naked eyes and grasp the insertion depth of the needle core 11.

[0038] Further, the sleeve 2 is a transparent tube. The doctor can observe the scale mark 22 pointed by the scale reference mark 141 with naked eyes, and master the insertion depth of the needle core 11.

[0039] Further, as shown in Figure 2 and Figure 3 , the sleeve 2 is provided with an abutting disc 24 away from the needle holder 1, the through hole 21 penetrates through the abutting disc 24, and the abutting disc 24 is integrally formed with the sleeve 2. When the needle core 11 is inserted into the subcutaneous tissue of the patient, the abutting disc 24 abuts against the skin of the patient. The diameter of the abutting surface of the abutting disc 24 is larger than the diameter of the sleeve 2, so that the contact area of the abutting disc 24 and the skin surface of the patient can be increased. The extrusion to the skin of the patient is avoided.

[0040] Further, the needle core 11 is a stainless steel needle, which comprises an integrally formed needle body 111 and a needle tip 112. The end of the needle body 111 away from the needle tip 112 is connected to the needle holder 1, and the needle body 111 is provided with an insulating layer.

[0041] It should be noted that the insulating layer provided on the needle body 111 can prevent the pulse electricity on the needle core 11 from leaking, so that the pulse electricity on the needle core 11 is concentrated on the needle tip 112, and the diagnosis and treatment effect is better. The thickness of the insulating layer is very small, and the diameter of the needle body is not increased. Preferably, the insulating layer is an insulating coating.

[0042] Further, the length of the needle core 11 is 55 mm, and the diameter of the needle core 11 is 0.36 mm.

[0043] In summary, the present application provides a nerve stimulation acupuncture needle. In use, the needle core 11 is slowly inserted into the subcutaneous tissue of the patient, and the sleeve 2 abuts against the skin of the patient. At this time, the needle holder 1 slides along the through hole 21 of the sleeve 2. The scale mark 22 pointed by the scale reference mark 141 on the needle holder 1 is the current insertion depth of the needle core 11 into the skin of the patient. Thus, the technical effect of helping the doctor to master the insertion depth of the needle core 11 is achieved.

[0044] Obviously, the above embodiments are only examples for clearly illustrating, but not limiting the implementation. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the implementations are not required or can not be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
