Abstract

The invention discloses a device for implementing an electrophysiological testing method of a CNAP-based auditory brainstem implant, comprising: an ABI electrode sheet, and any ABI electrode to be tested on the ABI electrode sheet is used as a stimulating electrode for use after implantation. Send out electrical stimulation; any other electrode on the ABI electrode sheet is used as the recording electrode of the stimulating electrode, and is used to receive the electrical stimulation signal sent by the stimulating electrode and record the action potential of the electrically stimulated cochlear nucleus; a signal acquisition device; and a signal processing device. The equipment provided by the present invention utilizes the ABI electrode sheet itself to complete electrical stimulation and recording. Any ABI electrode is used as a stimulating electrode and its adjacent motor is used as a recording electrode. The advantages of high signal-to-noise ratio, fast response, short recording time, and high anti-interference ability improve the efficiency of intraoperative electrode testing; it is suitable for use in auditory brainstem implantation surgery.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for realizing the electrophysiological testing method of the auditory brainstem implant (ABI) based on CNAP. Background technique [0002] ABI (auditory brainstem implant) is suitable for patients who are not suitable for cochlear implantation, such as cochlear aplasia, cochlear ossification, and auditory nerve absence. At present, it has not been widely carried out in China, and it has great application prospects. Good intraoperative detection is the guarantee for the effect of postoperative auditory reconstruction. [0003] The ABI device includes two parts: an in vitro device and an in vivo device. The extracorporeal device includes an electroacoustic converter, a speech processor and connecting leads; the in vivo device includes a receiver, electrode leads and electrode arrays (ie, auditory brainstem electrode sheets). The working principle of ABI is to place the ele...
