Bandage-free implanting device of artificial retina and artificial retina

Abstract

The invention provides a bandage-free implanting device of an artificial retina. The bandage-free implanting device comprises: a base body which covers an eyeball and is fixed on the eyeball; an electronic packaging body which is mounted on the base body, and is at least provided with a processing circuit for processing an electric signal; a stimulating electrode structure which is provided with a base end connected with the electronic packaging body, a stimulating end close to a retina in the eyeball through an incision in the eyeball, and an electronic cable used for connecting the base end and the stimulating end; a receiving antenna which is embedded into the base body, and is connected with the electronic packaging body, wherein the base body is molded into a non-closed-ring shape. According to the bandage-free implanting device of the artificial retina, the base body of the bandage-free implanting device of the artificial retina covers the outer surface of the eyeball and is molded into the non-closed-ring shape; furthermore, the stimulating end of the stimulating electrode structure is close to the retina in the eyeball through the incision in the eyeball, so that surgery traumas on the eyeball, particularly eyeball muscle, in a surgery implanting process of the implanting device of the artificial retina can be reduced.

Description

technical field [0001] The invention relates to an artificial retina implantation device without a bandage and the artificial retina. Background technique [0002] In the process of normal vision formation, the photoreceptor cells (including cone cells and rod cells) of the retina in the eyeball convert external light signals into visual signals, and the visual signals pass through the bipolar cells of the retina in turn along the vertical pathway of vision , ganglion cells, etc., and finally converge to the optic nerve and spread to the cortex of the brain, thus forming light perception. [0003] In some retinal diseases such as retinitis pigmentosa (RP) and age-related macular degeneration (AMD), the decline of photoreceptor cells is caused by retinitis pigmentosa and age-related macular degeneration. The light entering the eye cannot be converted into visual signals, resulting in the inability of the patient to perceive light and loss of vision. Fortunately, the functio...

Problems solved by technology

[0005] The inventors of the present invention have found through long-term research on implantation operations that in the above-mentioned cerclage surgery, although the implant device is used to cerclage the eyeball with a bandage, the firmness between the implant device and the eyeball has not been greatly improved. However, the cerclage of the above-mentioned implanted device has brought many adverse effects on the eyeball, such as large trauma to the eyeball, damage to the eye muscles, cumbersome operation process, long postoperative recovery process, and eye irritation symptoms of patients. Obvious, etc., and often due to bandages and other cerclages compressing the vortex vein of the eyeball, the blood circulation in the eye is not smooth, resulting in complications such as retinal ischemia and even choroidal leakage.
