Abstract

The implantable chip type optic nerve micro stimulating electrode in biomedicine engineering technology field includes an electrode substrate, micro electrodes, inner electrode leads, a lead base, lead interfaces and a cable bundle. Two or more micro electrodes constitute the micro electrode pair, the inner electrode leads connect the micro electrodes and the lead interfaces, the lead base and the electrode substrate are connect directly, the lead interfaces are distributed in the surface of the lead base, and the cable bundle consists of cables connecting the lead interfaces and the outer equipment. The present invention can stimulate the optic nerve fiber effectively and the optic nerve fiber conducts the stimulating current the stimulator produces to the optic cortex, so that the optic cortex produces excitation similar to that produced by the light stimulated retina, and generates visual hallucination, while recording the potential of the optic nerve fiber.

Description

technical field [0001] The invention relates to an electrode in the technical field of biomedical engineering, in particular to an implantable sheet-type optic nerve micro-stimulation electrode. Background technique [0002] For eyes with normal visual function, the objects watched by the outside world can be imaged on the retina, and the photoreceptor cells on the retina convert the image signal into a bioelectrical signal, and then pass through the retinal nerve composed of horizontal cells, bipolar cells and ganglion cells. After the network preliminarily processes the bioelectrical signals of photoreceptor cells, the visual nerve fibers sent by ganglion cells are transmitted to the visual cortex of the brain, and the visual cortex of the brain reprocesses the obtained bioelectrical signals to perceive and produce vision. However, some diseases, such as retinitis pigmentosa and age-related macular degeneration, will affect the photoreceptor cells of the retina, destroying...
