The artificial retina device and the like which uses the electrode component, and its electrode component for retina stimulus

摘要

There are no times when the retina is pressed over the wide scope above necessity the picture image which at the same time was really transmitted they designate that the artificial retina device which uses thing, and its electrode component which offer the electrode component for retina stimulus which image formation can do is offered as purpose.The electrode 2 which in length and breadth is arranged in matrix condition and, the support section the pin 4 for fixing where locks the four corners of 3 which keeps each electrode 2 in specified position and support section 3 in sclera A is provided in electrode component 1. Electrode 2 sudden facilities is done needle-shaped from opposition surface 3A side of support section 3 facing toward retina F. In addition, when support section 3 is locked on the retina, the fact that the advanced part 2A of electrode 2 contacts the retina dipole cell C is allowed in pin 4 for fixing, the positioning sudden section 5 which regulates the fact that the whole of the opposition aspect 3A contacts retina F is provided.
