Artificial cochlear implant device adopting multi-point loop electrode outside cochlea

Abstract

The invention relates to an artificial cochlear implant device adopting a multi-point loop electrode outside a cochlea. The artificial cochlear implant device comprises a radio frequency transceiver, a decoding stimulator connected with the radio frequency transceiver, a 22 to 24-lead stimulating electrode connected with the decoding stimulator and at least two loop electrodes, wherein the radio frequency transceiver is inductively coupled to an external coil to be positioned by adopting a detachable positioning magnet; and the decoding stimulator is packaged in a multi-layer sealing structure. The artificial cochlear implant device improves the stimulation mode of the electrode, improves the stimulation effect of the electrode, and can form the most effective three-dimensional stimulation loop to the cochlea and stimulate residual auditory nerve cells to achieve better performance.

Description

technical field [0001] The invention relates to an artificial cochlear implantation device, in particular to an artificial cochlear implantation device using extracochlear multi-head loop electrodes. Background technique [0002] Multi-channel cochlear implant (also known as: bionic ear, electronic cochlear, cochlear implant) is a multi-disciplinary combination of hearing science, information engineering, medicine, audiology, biomedicine, electronics, microelectronics technology and microprocessing technology. Modern high-tech products. Based on the theory of human ear speech analysis, it uses acoustic and electric transducers to replace the dysfunctional hair cells in the cochlea of ​​the deaf, and directly stimulates the auditory nerve with programmed current to reproduce the sensory mechanism of cochlear hearing, so that the deaf disabled can return to near normal hearing. [0003] The cochlear implant system includes two parts: 1. Speech processor, referred to as exter...

AI Technical Summary

Problems solved by technology

[0004] At present, Australia, Austria, the United States and other countries are developing cochlear implant projects in foreign countries. They started earlier and their products are relatively mature, but their technology is monopolized and the products are expensive, which are simply unacceptable to ordinary patients and families, and are not suitable for my country's national conditions.

The development of cochlear implants in China started relatively late, and the products have not yet entered the market. The reported products have a simple structure and can only realize some basic functions of the cochlea.

Especially in the cochlear implantation device, the receiver efficiency is low, the decoding stimulator has few functions, the sealing package structure of the decoding stimulator is simple, the stimulation structure of the electrode is simple, and the effect is not good
