An implantable peripheral nerve electrode

Abstract

The invention discloses an implantable peripheral nerve electrode, which belongs to the field of medical equipment. Including: electrode head, electrode head includes: openable ring base, multiple electrode wires and electrode wire implanted in the nerve guiding part, each electrode wire is fixed in the openable ring base, and its diameter is smaller than the openable The thickness of the ring-shaped base body, and the surface is covered with an insulating layer, one side is connected with the electrode wire implanted with the nerve guiding part, and the other side is connected with the corresponding jack of the plug end; the plug end includes a plurality of jacks for connecting with nerve signals Acquisition / stimulation equipment is connected. The present invention uses an openable ring matrix as the basic structure of the electrode, wraps the outer peripheral nerve trunk through the openable ring matrix, and fixes the electrode stably on the surface of the peripheral nerve to prevent displacement of the implanted electrode. Multiple electrode wires are guided by guide needles and implanted into targeted sites in different positions of the peripheral nerves to improve the spatial selectivity, accuracy and stability of peripheral nerve electrode recording and stimulation.

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
