Abstract

The invention discloses an artificial retina system which comprises an in-vitro part and an implantation part. The in-vitro part comprises a portable power source, vision glasses and a transmission coil. The portable power source is connected with the vision glasses to provide external power supply for the whole artificial retina system. The vision glasses comprise a camera lens, a main board and an interface board. The transmission coil is connected with a radio frequency modulation module and used for receiving an image coded signal. The implantation part comprises a receiving coil, a demodulation stimulating module and a stimulating electrode. The receiving coil is in alignment connection with the transmission coil. The demodulation stimulating module is connected with the receiving coil, decodes the image coded signal received by the receiving coil and converts the image coded signal into an electric signal to be transmitted to the stimulating electrode. The stimulating electrode comprises a plurality of contact electrodes and electrode wires connected with the contact electrodes one to one. The artificial retina system can directly stimulate retinal ganglion cells on the innermost layer, most electronic devices are arranged on the in-vitro part, and therefore images are updated and processed easily.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to an artificial retina system. Background technique [0002] In recent years, with the continuous advancement of science and technology, artificial retinal repair technology has been produced, which directly converts optical signals into electrical signals, and then uses electrical signals to stimulate retinal inner layer cells, which can restore the patient's vision to a certain extent. It has become a research hotspot in the field of visual restoration. The methods of retinal electrical stimulation are divided into two categories according to the location of the stimulating electrodes. One is implanted in the photoreceptor cell layer with a micro-current stimulation chip generated by photosensitive diodes, which is called sub-retina implant (Sub-retina implant), and its electrical stimulation targets are mainly bipolar cells; the other is radio frequency The electric current tr...
