Retina stimulation equipment based on two-dimensional array probes

Abstract

The invention discloses retina stimulation equipment based on two-dimensional array probes, and the equipment comprises a lens frame and the two-dimensional array probes, wherein the two-dimensional array probes are installed in the lens frame, and the lens frame is provided with a camera device, an integrated circuit, and a power supply. Coupling parts are disposed between the two-dimensional array probes and eyes. The camera device is used for collecting image information and transmitting the image information to the integrated circuit. The integrated circuit is used for converting the image information into an electric signal and transmitting the electric signal to the two-dimensional array probes. The two-dimensional array probes are used for generating ultrasound under the excitation of the electric signal, and achieving the ultrasonic stimulation of the retinas. The power supply is used for supplying power to the camera device and the integrated circuit. After a dysopia person wears the equipment, the integrated circuit enables the image information collected by the camera device to be converted into the electric signal, and the electric signal is used for the excitation of the two-dimensional array probes, thereby forming a focused sound beam with a plurality of focuses. The ultrasound acts on optic nerve cells, and enables the dysopia person to sense the image information, and to recover the visual sensing function.

Description

technical field [0001] The invention relates to the field of visual replacement technology, in particular to a retinal stimulation device based on a two-dimensional area array probe. Background technique [0002] With the development of society, more and more attention has been paid to the health of the disabled. Many blinding diseases are found today. The patient's lens is blurred or the surface cells of the retina can no longer work, but the cells below the surface are still healthy and alive. There are many blind prosthetics that use electrical stimulation to help blind people restore visual function, but electrical stimulation requires surgery to implant chips in the human body, which is far behind ultrasonic stimulation in terms of non-invasiveness and safety. [0003] The visual imaging process of the human eye is that the reflected light of the object is refracted and imaged on the retina through the lens, and then transmitted to the brain by the visual nerve percepti...
