Patent ID: 8676334

Claim:
A peripheral nerve interface system, comprising: a nerve conduit configured to be connected to a terminal of a damaged peripheral nerve at a cut body portion; a prosthesis for substituting for the cut body portion; and a peripheral nerve interface unit electrically connected to the nerve conduit and the prosthesis to restore a function of the damaged peripheral nerve and control operations of the prosthesis by transmitting and receiving signals of the damaged peripheral nerve, wherein the nerve conduit comprises: a support connected to the terminal of the damaged peripheral nerve; a channel formed in a body of the support and having a cavity shape; an electrode layer formed along an inner wall of the channel; and an external electrode electrically connected to the electrode layer, wherein the channel is configured for permitting growth of a nerve cell along the channel at the terminal of the damaged peripheral nerve, and the electrode layer is configured to electrically connect to the nerve cell having grown along the channel, wherein the support comprises a plurality of channels, and the peripheral nerve interface unit comprises: an internal module configured for being implanted into a damaged body portion and electrically connected to the nerve conduit; and an external module configured for being positioned out of the damaged body portion and electrically connected to the prosthesis, wherein the internal module and the external module are configured for transmitting and receiving nerve signals to/from each other in a wireless communication manner, and the internal module comprises: a first amplifying unit for amplifying the signal of the damaged peripheral nerve received through the nerve conduit; a first AD converter for converting the signal amplified by the first amplifying unit into a digital signal; a first digital signal processing unit for receiving and analyzing the digital signal converted by the first AD converter and transmitting the digital signal to the external module in a wireless communication manner, or receiving and analyzing the digital signal received from the external module and transmitting the digital signal to the grown nerve cell through the channel; a DA converter for converting the digital signal received by the first digital signal processing unit into an analog signal; a stimulating unit for transferring an electric stimulation signal to the grown nerve cell along the plurality of channels by using the analog signal converted by the DA converter; a multiplexer for electrically matching a plurality of nerve cells having grown along the plurality of channels according to an instruction of the first digital signal processing unit with the first amplifying unit and the stimulating unit; and a first communication unit for transmitting and receiving signals to/from the external module in a wireless communication manner, and wherein the first digital signal processing unit is configured for adopting a multilayer perceptron algorithm.
