An electrophysiological testing device for automated auditory brainstem implants

Abstract

The invention discloses an electrophysiological testing device for an automated auditory brainstem implant ABI. The device includes: a stimulus generator, several ABI electrodes, recording electrodes, a signal receiving device, and devices connected to the signal receiving device respectively. A signal acquisition device and a signal processing device; the method of use of the device includes: step 1, electrically stimulating several ABI electrodes through a stimulation generator; step 2, each ABI electrode correspondingly receives an electrical stimulation signal, and stimulates the central auditory system , generate the electrical stimulation auditory brainstem evoked potential, and the recording electrode in the patient records the electrical stimulation auditory brainstem evoked potential; Step 3, the signal receiving device is connected with the signal acquisition device and the signal processing device respectively, and receives the recording electrode collected by the signal acquisition device. For the recorded electrical stimulation auditory brainstem evoked potentials, the signal processing device determines whether the corresponding ABI electrodes have electrical stimulation auditory brainstem evoked potential target waveforms.

Description

Technical field [0001] The present invention relates to the field of hearing brake implantation, and in particular, to an electrophysiological test apparatus for automated listening brake implant ABI. Background technique [0002] Listening to the brain-dry implant (ABI) is suitable for patients with cochlear unstoppartum, cochlear ossification, and listening to nerves, such as unsuitable cochlear implantation. The ABI device includes two portions of in vitro devices and in vivo devices, in vitro devices including electroacouoeia, speech processors, and connection conductors, and in vivo devices include receivers, electrode wires, and electrode arrays. [0003] The working principle of ABI is to place the electrode array in the surface of the wards in the fourth lateral ventricle, cross the cochlear and listening to nerve, directly stimulate the snail roller complex, generate speech perception and identification. Among them, the number of ABI electrode arrays is due to the brand,...

AI Technical Summary

Problems solved by technology

[0006] There are the following deficiencies or shortcomings in the prior art: (1) At least 4 experienced audiologists are required to work together, and at the same time take into account the work of judging waveforms, feedback stimulus information and drawing, and judging eABR waveforms has a certain degree of subjectivity; ( 2) The process is cumbersome and takes a long time, which significantly increases the patient's anesthesia time and the waiting time of the surgeon and anesthetist; (3) The surgeon needs to spend time understanding and judging the two-dimensional plan feedback from the audiologist, lacking three-dimensional structure guidance , it is difficult to adjust the electrode position adjustment
