Deep brain stimulation device having wireless power feeding by magnetic induction

摘要

Provided is a deep brain stimulation (DBS) device having power wirelessly fed by magnetic induction. A rotating magnetic field is formed using a rotating magnetic field disk installed inside a hat of a patient. The rotating magnetic field generates induced power using an induction coil plate fixed underneath a scalp of the patient to drive electrodes implanted into a brain of the patient so as to correct abnormal motor and sensory functions of the patient using power wirelessly fed from an external device into the electrodes. The DBS device includes: a hat module installed inside a hat of the patient to generate a rotating magnetic field; and an implantation module implanted through a skull under a scalp to contact a nervous system of the patient and combined with the rotating magnetic field of the hat module to stimulate the cerebral nerve using induced power generated by the magnetic induction.
