Abstract
Description
Technical Field
[0001] The present application relates to the field of neuro-electrophysiological equipment, and in particular to a needle electrode body. Background Art
[0002] The needle electrode includes a needle body and a solid needle. In the prior art, the solid needle is generally welded directly to the needle body, and then the solid needle is fixed in the needle handle. However, in actual applications, the solid needle and the needle body are often desoldered. The separation of the solid needle and the needle body will affect the use of the needle electrode equipment and reduce the service life of the needle electrode. Summary of the invention
[0003] The purpose of this application is to propose a needle electrode needle body to solve the above technical problems.
[0004] A needle electrode needle body comprises a needle body portion and a solid needle fixedly connected to the needle body portion, wherein the upper surface of the needle body portion is provided with a plurality of recessed portions recessed downward therefrom in parallel, and the solid needle is provided with a plurality of raised portions in parallel, and each raised portion is fixedly connected to each recessed portion.
[0005] Preferably, each recessed portion is arranged along the length direction of the needle body.
[0006] Preferably, each protrusion is arranged along the length direction of the solid needle.
[0007] Preferably, each protrusion is welded into each recess and is also fixed by sandblasting.
[0008] Preferably, a first contact end is disposed between every two adjacent recessed portions.
[0009] Preferably, a second contact end is disposed between every two adjacent protrusions.
[0010] Preferably, each first contact end is fixedly connected to each second contact end.
[0011] Preferably, the first contact end is welded to the second contact end.
[0012] Preferably, at the connection between the solid needle and the needle body, the end of the solid needle is bent and extends toward the end of the needle body.
[0013] The beneficial effect is that by setting a fixedly connected recessed portion and a raised portion, the fixation of the needle body and the solid needle is strengthened, and since the needle body is usually subjected to axial force, setting the recessed portion can reduce the axial force of the connecting portion between the two and play a buffering role. Furthermore, the part where the recessed portion and the raised portion are connected can be sandblasted to prevent the solid needle from detaching from the needle body.

[0024] like Figures 1 to 3 As shown, this is Example 1 of the present application:
[0025] A needle electrode needle body comprises a needle body portion 1 and a solid needle 2 fixedly connected to the needle body portion 1, wherein the upper surface of the needle body portion 1 is provided with a plurality of recessed portions 11 recessed downward therefrom in parallel, and the solid needle 2 is provided with a plurality of raised portions 21 in parallel, and each raised portion 21 is fixedly connected in each recessed portion 11 respectively.
[0026] Each recessed portion 11 is arranged along the length direction of the needle body 1 .
