Abstract

The invention discloses a foldable minimally-invasive artificial retina microelectrode array. The array comprises a foldable soft substrate, wherein a first connecting terminal array area and a second connecting terminal array area are arranged at the two ends of the soft substrate respectively, the first connecting terminal array area is composed of first connecting terminals, the second connecting terminal array area is composed of second connecting terminals, an exciting electrode array area is arranged on the soft substrate and composed of exciting electrodes, the first connecting terminal array area is connected with the exciting electrode array area through a flat cable, the second connecting terminal array area is connected with the exciting electrode array area through a flat cable, suture holes are formed in the edge of the soft substrate, and the exciting electrode array area is of a semispherical structure. The foldable minimally-invasive artificial retina microelectrode array can make good contact with the macular area of the retina, the exciting effect is better, the array is foldable so that the array can be embedded into one eye through a small incision, the wound is small, the array can be conveniently embedded in, wound inflammation can be reduced through contained drugs, and the treatment effect is improved.

Description

technical field

[0001] The invention belongs to the field of medical devices, in particular to a foldable minimally invasive artificial retinal microelectrode array. Background technique

[0002] Artificial vision is composed of electrodes implanted in the eyeball, a picture processor, a micro-camera and a transmission device. The image is recorded by a micro-camera and converted into an electrical signal, and then sent to the image processor to amplify and filter the signal, and then sent to the receiver by the transmitter, and the generated electrical pulse is sent to the corresponding stimulating electrode contact, thereby stimulating the retina The nerve cells in the lower layer of the inner surface excite the optic nerve and transmit image information to the brain to form vision. In the whole artificial vision system, the artificial vision electrode is a very important part of the artificial vision implant.

[0003] Whether the artificial vision implant can remain in ...
