Implantable peripheral nerve electrode

Abstract

The invention discloses an implantable peripheral nerve electrode and belongs to the field of medical equipment. The implantable peripheral nerve electrode comprises an electrode tip and a plug end and is characterized in that the electrode tip comprises an openable annular base, a plurality of electrode wires and electrode wire implanting nerve guide parts, each electrode wire is fixed in the openable annular base, the diameter of each electrode wire is smaller than the thickness of the openable annular base, each electrode wire is covered with an insulating layer, one side of each electrodewire is connected with the corresponding electrode wire implanting nerve guide part, and the other side of each electrode wire is connected with the corresponding insertion hole of the plug end; the plug end comprises multiple insertion holes and is used for being connected with nerve signal collecting / stimulation equipment. The implantable peripheral nerve electrode has the advantages that the electrode uses the openable annular base as the basic structure of the electrode, the openable annular base wraps the peripheral nerve trunk to allow the electrode to be stably fixed to the surface of the peripheral nerve, and displacement of the implanted electrode can be prevented; the electrode wires implanted into target loci at different positions of the peripheral nerve under the guidance of guiding needles, and the recording and stimulation space selectivity, accuracy and stability of the peripheral nerve electrode are increased.

Description

technical field [0001] The invention belongs to the field of medical equipment, and more specifically relates to an implantable peripheral nerve electrode. Background technique [0002] Implant peripheral nerve electrodes on peripheral nerves to construct peripheral nerve interfaces. On the one hand, peripheral nerve signals can be recorded, and external equipment can be controlled by decoding peripheral nerve motion control commands, which can be used to repair the motor function of physically disabled people; On the one hand, electrical stimulation can be applied to peripheral nerves through peripheral nerve electrodes, and can be used to restore sensory functions of physically disabled people. In addition, electrical stimulation based on peripheral nerve electrodes is also widely used in functional electrical stimulation and electrical stimulation of the vagus nerve. [0003] Although the traditional implantable peripheral nerve electrodes have undergone considerable dev...

AI Technical Summary

Problems solved by technology

[0003] Although the traditional implantable peripheral nerve electrodes have undergone considerable development and improvement, they still face the following problems: (1) The peripheral nerve electrodes implanted in the peripheral nerve bundle are difficult to fix, and are prone to displacement, which affects the use and quality of the peripheral nerve electrodes. Stability; (2) The spatial selectivity of peripheral nerve electrodes is not high, and the effective implantation of multiple specific sites on the peripheral nerve cannot be realized; (3) The peripheral nerve electrodes have requirements for the size of the peripheral nerve, and it is impossible to implant small peripheral nerve
