Cochlear implant simulation neural telemetry system and method

Abstract

The invention discloses an artificial cochlea simulation neural remote measurement system and method. The system comprises a signal generator, a salinity test meter, a converter, a debugging box, a language processor and an implantation material, the signal generator is used for receiving synchronizing signals and outputting sine wave simulation neural signals, the input end is connected with the language processor, and the output end is connected with the converter; the salinity test meter is used for testing the brine water concentration of the placed implantation material; the converter is used for isolating saline water from the signal generator, the input end of the converter is connected with the signal generator, and the output end of the converter is placed in the saline water where the implantation material is located; the debugging box is used for converting commands sent from a computer into signals which can be accepted by the language processor, the input end of the debugging box is connected with the computer, and the output end of the debugging box is connected with the language processor. By means of the artificial cochlea simulation neural remote measurement system and method, the risk of artificial cochlea failure due to stimulation is reduced, the troubleshooting and debugging prior to implantation can be achieved, and the clinical research after the implantation is facilitated as well.

Description

technical field [0001] The invention relates to the technical field of cochlear implants, in particular to a cochlear artificial nerve telemetry system and method. Background technique [0002] The rapid development of cochlear implants has brought good news to tens of millions of severe and extremely severe deafness patients, improving the quality of life to the greatest extent, and returning to the world of sound. However, cochlear implant equipment requires high technology, and it is generally impossible to directly judge the patient's use effect and the corresponding auditory nerve activity during the operation, so we need to perform some intraoperative tests during the operation, such as implant electrode impedance measurement, electrical stimulation Auditory brainstem evoked potential (EABR), stapedius reflex, neural response telemetry (NRT), etc., objectively evaluate the working status of implant electrodes in the cochlea. At the same time, because the age of the im...

AI Technical Summary

Problems solved by technology

[0003] Generally, NRT is carried out during or after implantation. If an electrode stimulation problem that cannot be solved by debugging software is found, it will not only cause unnecessary harm to the human body, but also waste a set of expensive cochlear implants.
