Intracranial noise suppression apparatus

摘要

An apparatus for suppressing an induced intracranial noise or vibrational signal within a patient's head due to a drilling or cutting medical instrument. The apparatus includes a mechanism for sensing the intracranial vibrational signal induced within the patient's head. The apparatus also includes a mechanism for adaptively generating an intracranial vibrational suppression signal from the intracranial vibrational signal as a function of time. In addition, the apparatus provides a mechanism for applying the intracranial vibrational suppression signal to the patient's head for suppressing the induced intracranial noise or vibrational signal.
