Abstract

The invention discloses an artificial retina stimulating electrode and a manufacturing method therefor. The simulating electrode comprises an electrode head portion, a thin portion, an electrode body portion and a connection portion. The electrode head portion comprises an elliptical flexible substrate, a first fixing nail, a second fixing nail, a contact electrode and a wire electrode connected to the contact electrode, and the electrode wire penetrates the thin portion, the electrode body portion and the connection portion. The thin portion is connected to the electrode head portion. The electrode body portion is connected to the thin portion. The connection portion is connected to the electrode body portion via a circular bead, and comprises a conical portion, a triangular portion a loop electrode and a loop wire electrode connected to the loop electrode. The artificial retina stimulating electrode can make contact with a macula lutea zone of the retina, the effect of simulation is good, the size of the artificial retina stimulating electrode is small, so the artificial retina stimulating electrode can be implanted in the eye through a small incision, so the artificial retina stimulating electrode is convenient to implant and fix with a small incision.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an artificial retina stimulating electrode and a manufacturing method thereof. Background technique [0002] The artificial retina 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 visual system, artificial retina stimulating electrodes are very important components. [0003] The size of artificial retinal stimulation electrodes, the ...
