Retinal prosthesis

Abstract

The present invention relates to the medical instrument field, especially to a retinal prosthesis. The retinal prosthesis comprises a stimulation module implanted in the internal portion of an eye tissue, a communication module is arranged at a sclera of the outer wall of an eyeball, and the communication module is internally provided with a first processing chip. A second processing chip is synchronously installed on the stimulation module at the internal portion of a patient's eye tissue to allow microelectrodes to directly connect with the second processing chip and then connect with the first processing chip arranged at the external portion of the eye tissue through the second processing chip. The defects are solved that traditional microelectrodes need wires to directly connect with a processing chip arranged at a sclera of the outer wall of an eyeball to greatly reduce the quantity of the wires and allow the number of the wires not to be increased with the number of the microelectrodes so as to greatly reduce damaging of the eye tissue caused when a retinal prosthesis is implanted and accelerate healing of the eye tissue.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a retinal prosthesis. Background technique [0002] Implantable neurostimulators are widely used in medicine. As an important tool for treating neurological diseases, microelectrode stimulators have attracted more and more attention, and have become an important research direction. [0003] People's application of microelectrodes is usually to implant microelectrodes into animals or patients, to stimulate or inhibit neural activity by loading electrical signals, or to use microelectrodes to convert neural activity into electrical signals and record them for research. [0004] In the artificial retina, it is often necessary to implant microelectrodes into the eyeball tissue of animals or humans, and then set a processing chip at the sclera of the outer wall of the eyeball tissue to control the microelectrodes, and each microelectrode needs to be connected to the sclera by wires for ...

AI Technical Summary

Problems solved by technology

[0005] Since the number of microelectrodes is generally large and there are many wires that need to be connected, this method will lead to larger wiring width, larger trauma to the patient, and slower postoperative healing

At the same time, when the number of electrodes increases to a certain number, the connection of wires also becomes a technical bottleneck, resulting in the inability to connect
