specific Embodiment

[0018] The present invention is a light-controlled cochlear implant, such as figure 1 As shown, it includes a voice collection device, a voice processing device, a transmission device and a cochlear implantable light stimulation device. The voice collection device converts sound into electrical signals and inputs them into the voice processing device. The light stimulation device is a blue light source containing a wavelength of 473nm Micro LED lights with a yellow light source with a wavelength of 593nm and a flexible optical fiber output end arranged on the back of the tiny LED lights; the voice processing device encodes the electrical signals transmitted to the voice collection device in real time, and the encoded electrical signals control the lights of the tiny LED lights Source switch, light frequency, pulse width and intensity, and the alternating time of the blue and yellow light sources; the encoded electrical signal is input to the tiny LED lamp through the transmissi...

Abstract

The invention discloses a light-operated artificial cochlea device, which comprises a voice acquisition device, a voice processing device, a transmission device and a photic stimulation device capable of implanting cochleas, and is characterized in that the photic stimulation device comprises a micro LED (light-emitting diode) lamp containing blue and yellow light sources, and a flexible optical fiber output end connected with the micro LED lamp, the voice processing device is used for coding received electrical signals, the coded electrical signals are used for controlling the on and off of the lamp sources of the micro LED lamp, the frequency, the pulse width and the intensity of light and the alternating time between the blue light source and the yellow light source, the micro LED lamp applies the received electrical signals to driving the micro LED lamp and generating corresponding photic stimulation signals, and the photic stimulation signals are transmitted to spiral ganglion cells of photogenes expressing sensitivity to blue and yellow in advance through the flexible optical fiber output end and drive the spiral ganglion cells to generate excitement and inhibition intermittent auditory nerve impulse with certain frequency and a certain mode. The light-operated artificial cochlea device has the advantages of little trauma, simplified operation, high success ratio of an operation and high natural sound degree.

Description

technical field [0001] The invention relates to a cochlear artificial device, in particular to a light-controlled cochlear artificial device. Background technique [0002] A cochlear implant is a device that replaces the function of the human cochlea. It can help adults and children with severe deafness (with some remaining normal spiral ganglion cells) to restore hearing. After decades of development, especially with the emergence of high-tech such as biomedical engineering in recent years, cochlear implant technology has been widely used in clinical practice from experimental research, and has become an effective treatment for total deaf patients to restore hearing. According to statistics, there are more than 50,000 deaf patients worldwide who have used cochlear implants. A cochlear implant consists of electrodes implanted in the cochlea, a speech processor, a directional microphone and a transmission device. The sound is received by the directional microphone and conve...
