System for treating blindness

Abstract

The invention discloses a system for treating blindness. The system for treating blindness comprises a femtosecond laser operating device, an operating table, a computer, a biological printing device,a femtosecond phase imaging device and an XYZ precise manipulator platform; the operating table is a working table used during treatment on a patient; the femtosecond laser operating device is used for removing necrotic optic cells of eyes of the patient by using femtosecond laser; the biological printing device is used for printing required live optic cells; the XYZ precise manipulator platformis used for injecting the live optic cells into the eyes; the femtosecond laser operating device is further used for repairing and adjusting the live optic cells injected into the eyes so that necrotic regions are accurately filled with the injected optic cells; the femtosecond phase imaging device is used for monitoring the whole process in real time; and the femtosecond phase imaging device andthe femtosecond laser operating device are connected with the computer to dynamically control and manage the whole process in real time by the computer. A new method and a brand-new automatic operating system device are provided for treatment of blindness of eyes.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a system for treating eye blindness. technical background [0002] Retinopathy destroys the photoreceptor cells in the retina, making it impossible for patients to transmit external light stimuli to the nerve center. There is also an increasing proportion of older persons in the population who are blind due to retinal degeneration. Vision usually begins with rods and cones (also known as photoreceptors) that convert light signals into electrical signals, then pass through second- and third-order retinal neurons and optic nerves to the lateral geniculate nucleus, and then to the visual imagery Cortex (Document 1). In patients with visual impairment due to loss of photoreceptors, depending on the nature of the specific impairment, vision may be induced by delivering electrical stimulation at one of these downstream neuronal locations. But if the damage cann...

Problems solved by technology

Artificial retina chip surgery is limited by the complex micro-electromechanical structure, biocompatibility, complexity of surgical implantation, and the number of metal microelectrode arrays, which make it impossible to obtain good clinical surgical results. The pixel is improved, but at the same time it will cause thermal effect, and the thermal effect will cause damage to the eyes to a certain extent. There is an irreconcilable relationship between the two. At present, the US News has conducted research on retinal chips due to the thermal effect caused by the increase in the number of microelectrodes. negative press
