In addition, the drawings are only schematic illustrations of the present application and are not necessarily drawn to scale.

It is understood that if the device of the diagram is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0035] The terms "a", "an", "the" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second" are used merely as labels and are not intended to limit the quantity of their objects.

[0036] Example 1

[0037] This embodiment provides a specific implementation of a device for establishing a peripheral nerve electrical stimulation channel, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a puncture needle 3, a puncture target point confirmation probe 4, a pusher 6 and an electrode wire 5. The puncture needle 3 can penetrate into human tissue to form an intervention channel. After the puncture needle 3 penetrates into human tissue, the position of the needle tip of the puncture needle 3 is confirmed by the puncture target point confirmation probe 4. After the puncture target point confirmation probe 4 confirms that the needle tip of the puncture needle 3 has reached the target position, the electrode wire 5 is implanted to the target nerve fiber target position through the intervention channel formed by the puncture needle 3 under the action of the pusher 6.

[0038] In this embodiment, Figure 5 As shown, the electrode wire 5 includes a conductive part 1 and an insulating layer 2, the insulating layer 2 is wrapped around the outside of the conductive part 1, and both ends of the electrode wire 5 are exposed and not wrapped by the insulating layer 2, wherein the insulating layer 2 is an insulating medical polymer material, which can be polyethylene, polypropylene, polyacrylate, aromatic polyester, silicone rubber, polyurethane, polyetheretherketone, etc., and the conductive part 1 can be gold, silver, platinum, tungsten and alloys thereof, etc.

[0039] In this embodiment, Figure 6As shown, the electrode wire 5 is provided with an electrical stimulation signal path, and the electrical stimulation signal path includes a circuit trace, one end of the circuit trace is provided corresponding to the body surface electrode, and the other end of the circuit trace is provided corresponding to the target nerve fiber target point, so as to transmit the body surface electrode signal to the target nerve target point. Specifically, two electrical stimulation signal paths are provided on the electrode wire 5, and the two electrical stimulation signal paths and their corresponding body surface electrodes form a stimulation circuit.

[0040] In this embodiment, the puncture target point confirmation probe 4 is a wire that can send out electrical stimulation signals. After the distal end of the puncture needle 3 contacts the target nerve target, the puncture target point confirmation probe 4 sends out a suitable electrical stimulation signal. At this time, the muscle controlled by the target nerve produces macroscopic shaking or the surface of the muscle controlled by the target nerve can collect electromyographic signals of a certain amplitude, which proves that the puncture needle 3 has reached the target target position.

[0041] Furthermore, if Figure 6 and Figure 7 As shown, the electrical stimulation signal path includes circuit lines AA and BB, wherein the AA line corresponds to the surface electrode a setting, and the BB line corresponds to the electrode b setting, wherein the AA line and the BB line are independently insulated from each other on the electrode wire 5, wherein the A2 point of the target nerve fiber target is connected to the surface electrode stimulation signal receiving point A1 through the AA line, and the B2 point of the target nerve fiber target is connected to the surface electrode stimulation signal receiving point B1 through the BB line, and the stimulation signals emitted by the surface electrodes a and b are transmitted to the A2 point and the B2 point through the AA line and the BB line, and the target nerve fiber target is electrically stimulated. The surface electrode a, the surface electrode b, the subcutaneous human tissue, the BB line, the electrode wire 5, the inter-nerve fiber tissue, the nerve fiber, and the AA line together form an electrical stimulation path, and the electrical stimulation signals emitted by the surface electrodes a and the surface electrodes b can be transmitted to the target fiber target position.

[0042] In some other embodiments, the electrical stimulation signal pathways may be provided in multiple groups, not limited to two groups, and the multiple groups of electrical stimulation signal pathways may form an electrical stimulation circuit.

[0043] In some other embodiments, the number of electrode wires 5 is not specifically limited and may be two, three or more.

After confirmation by the puncture target point confirmation probe 4, the puncture target point confirmation probe 4 withdraws the intervention channel formed by the puncture needle 3, places the electrode wire 5 and the pusher 6 in the intervention channel, and slowly pushes the electrode wire 5 to the target position for establishing the channel through the pusher 6.
