The invention relates to a low-damage implanted nerve
electrode. The low-damage implanted nerve
electrode comprises a base portion, a connecting portion and a
handle portion; flexible hinges are connected between the base portion and the connecting portion; and one end of the
handle portion is connected with the connecting portion. According to the low-damage implanted nerve
electrode of the invention, the base is designed based on a flexible mechanism design ideal, and therefore,
coupling degree between the electrode and an
brain tissue interface can be enhanced, and
fretting damage caused by long-term contact between the electrode and a nerve tissue can be decreased in a multi-degree-of-freedom manner; the front end of the
handle is designed to a semicircle corner, so that
fretting damage can be further reduced; and the exterior of the electrode is provided with an outwards-protruding streamline degradable
coating, so that electrode implantation damage can be reduced. The implantation shape of the electrode and the
fretting working state shape of the electrode do not interfere each other; acute injuries are smaller when the electrode is implanted; when the electrode works for a long time, fretting damage can be decreased in a plurality of directions; damage to
nerve cells can be decreased through the integration of many aspects; the reliability of the
micro electrode can be improved; and the nerve electrode can be left
in vivo for a long term stably.
