Title:

ELECTROPHYSIOLOGICAL TEST METHOD FOR AUDITORY BRAINSTEM IMPLANT AND RECORDING ELECTRODE USED BY METHOD

Document Type and Number:

WIPO Patent Application WO/2020/249069

Kind Code:

A1

Abstract:

The present application belongs to the field of medical devices, and relates to an electrophysiological test method for an auditory brainstem implant (ABI) and a recording electrode used in the method. According to the method of the present application, there is no need to subcutaneously place an additional recording electrode for a patient, so as to simplify the preoperative preparation. Moreover, the method has the advantages of being high in signal-to-noise ratio, high in reaction speed, short in recording time, and good in anti-jamming capability, can improve the intraoperative electrode testing efficiency, and is suitable for being used in an auditory brainstem implantation operation. According to the present application, the auditory brainstem implantation positioning is more accurate, and the application range thereof is expanded.
