Claim Text:
1. A method for analyzing nerve fibers distribution using a plurality of sensing and conducting electrodes on the surrounding of or inside a nerve tissue, comprising the steps of: (1) inputting a stimulation signal into the nerve tissue through at least two of the plurality of sensing and conducting electrodes, and applying a stimulation signal ratio to control the stimulation signal using an electric current steering technique to form at least one of a plurality of stimulation areas in the nerve tissue and to form at least one of a plurality of evoked compound action electric potentials (ECAPs) corresponding to at least one of the plurality of stimulation areas based on the stimulation signal ratio; (2) receiving at least two of the plurality of ECAPs using at least one of the plurality of sensing and conducting electrodes; and (3) computing a distribution angle corresponding to each of the plurality of sensing and conducting electrodes that are not used for inputting a voltage signal into the nerve tissue based on an electric potential attenuation factor, the voltage signal and the plurality of ECAPs, integrating and comparing the received at least two of the plurality of ECAPs to analyze the nerve fibers distribution in the nerve tissue based on the electric potential attenuation factor, a relative distribution of at least one of the plurality of sensing and conducting electrodes and a distance between a nerve fiber and at least one of the plurality of sensing and conducting electrodes within at least one of the plurality of stimulation areas.
