In existing technologies, the connecting wire is prone to breakage due to bending when the operator uses the needle electrode, resulting in signal interruption and affecting the transmission efficiency. Furthermore, the connecting wire tends to accumulate inside the needle electrode, which also makes it very easy for it to break. Summary of the Invention

[0016] Its beneficial effects are: the second slot is used to fix the probe part and prevent the probe part from shifting position, and the wire part is taut on the first slot, which can prevent the wire part from bending inside the needle handle, especially preventing the metal wire inside the wire part from breaking after bending.
[0017] In some embodiments, the shape of the first slot can match the shape of the lead wire portion; the first slot includes one or more slots arranged along the length of the needle shank.

[0040] Its beneficial effects are as follows: by setting the first slot 11, the lead wire 3 can be locked in the first slot 11, which can fix the position of the lead wire 3 and prevent the lead wire 3 from moving freely or bending in the needle handle 1; the wire organizer 6 can support the lead wire 3 after it leaves the needle handle 1, preventing the lead wire 3 from bending too much after leaving the needle handle 1 and causing a circuit break. Ultimately, it prevents the problem of electrical signal disconnection after the lead wire 3 bends, and improves the stability and accuracy of the nerve probe.
[0041] Preferably, the probe part 2 is provided with a bending part 5 at its end. The bending angle of the bending part 5 is generally selected as 90 degrees or 120 degrees. The bending angle of the bending part 5 can be selected according to the specific use environment. Generally, an angle-adjustable bending device is used to bend the probe part 2.
[0042] Preferably, the probe section 2 includes a first probe 21 and a second probe 22 located on one side thereof, and the first probe 21 and the second probe 22 are electrically connected to the wire section 3 respectively.
[0043] Preferably, the lead wire portion 3 includes a first lead wire 31 and a second lead wire 32. The first lead wire 31 can be electrically connected to the first probe 21, and the second lead wire 32 can be electrically connected to the second probe 22.
[0044] Preferably, the needle handle 1 is provided with a first slot 11 and a second slot 12 located on one side of the first slot 11. The second slot 12 is used to engage the probe part 2, and the wire part 3 engaged in the first slot 11 is taut.
[0045] Its beneficial effects are: the second slot 12 is used to fix the probe part 2 to prevent the probe part 2 from shifting position, and the wire part 3 is taut on the first slot 11, which can prevent the wire part 3 from bending in the needle handle 1, especially to prevent the metal wire inside the wire part 3 from being bent and breaking.
[0046] Preferably, the shape of the first slot 11 can match the shape of the lead wire portion 3; the first slot 11 includes one or more slots 111 arranged along the length direction of the needle handle 1.
[0047] Its beneficial effects are: it strengthens the fixation of the first slot 11 on the wire part 3, and the setting of several slots 111 improves the stability of the connection of the wire part 3, preventing the internal metal wire from breaking after the wire part 3 is bent. The shape of the first slot 11 is preferably arc-shaped.
[0048] Preferably, the shape of the second slot 12 can match the shape of the probe part 2. The shape of the second slot 12 is preferably arc-shaped.
[0049] Its beneficial effect is that it strengthens the fixation of the probe part 2 by the second slot 12.
[0050] Preferably, the needle handle 1 is integrally injection molded.
[0051] Its beneficial effects are: it can improve the life of the needle handle 1, the edge of the needle handle 1 is less likely to produce burrs, and the opening on the needle handle 1 is less likely to produce cracks.

[0053] Preferably, the cable organizer 6 is a mesh tail, which is made of soft rubber. During daily use of the nerve probe, especially when moving the probe, the lead wire 3 experiences the most frequent stress at the mesh tail location. Therefore, adding a mesh tail effectively increases the stress-bearing area of the lead wire 3, increasing its bending radius. Consequently, the metal wire inside the lead wire 3 is less likely to break after bending, preventing signal disconnection, and the rubber layer of the lead wire 3 is less prone to damage.
[0054] Preferably, the lead wire portion 3 and the probe portion 2 are connected by a copper strip. In the prior art, the lead wire portion 3 and the probe portion 2 are generally connected together by soldering, which has poor conductivity and is prone to contamination during soldering.

The plug 4 can be connected to a measuring device.
[0056] At the end where the wire part 3 is electrically connected to the plug 4, the first wire 31 and the second wire 32 will be connected in a specific configuration to prevent wiring clutter. Figures 2-3 As shown, they are spirally wound together. It should be emphasized that this winding method will not cause the conductor part 3 to break the circuit. Other solutions to prevent the circuit from becoming messy can also be selected, such as fixing the first conductor 31 and the second conductor 32 with straps or bands.
[0057] When using this nerve probe, the operator holds the needle handle 1 and inserts the probe part 2 into the patient's muscle tissue. The electrical signal generated in the patient's muscle tissue is transmitted sequentially through the probe part 2, the lead part 3, and the plug 4 to the measuring device connected to the plug 4.
