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

Embodiment Construction

[0028] In order to facilitate understanding of the present invention, it is described below in conjunction with accompanying drawing:

[0029] like Figure 1-7 As shown, the present invention provides a retinal prosthesis, including a stimulation component 1 implanted inside the human eyeball, and a communication component 7 arranged on the sclera of the outer wall of the eyeball. The communication component 7 includes a package body 2 and a coupling coil 3 . The package body 2 and the coupling coil 3 are generally wrapped by a silicone protective layer. When in use, the silicone protective layer wraps the communication component and the stimulation component, and is integrally formed to form a connection belt, and the communication component 7 is fixed on the outer wall 61 of the eyeball through the connection belt 4 .

[0030] A suture opening 41 is generally provided at the position of the communication component 2 or the connection belt 4 , through which the retinal prost...

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 ...
