Vision disorders and even loss seriously affect the quality of life of patients, and a large number of artificial vision devices have been developed at present, and can be mainly divided into two types: one is a visual replacement device that conveys visual information to the patient by other means such as touch or auditory; another category is techniques that attempt to restore visual function, such as retinal prostheses.
The main working mode of the current vision recovery technology is to directly stimulate the optic nerve through an electrode array or a photoelectric array device implanted on the retina so as to enable a wearer to generate vision, and bypass the process of converting light into electric signals through the retina. However, the perception and integration of color vision is mainly accomplished by the response of cone cells and rod cells on the retina to light, so that the existing electrode array implant has the problem that the patient can feel the outline of the object but cannot feel the color of the object, which greatly weakens the visual perception of the external world by the visually impaired patient.

In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides an intraocular projection device implanted into an eyeball, which comprises a front end fixing ring, a support bracket, an eyeball-crossing interface and a subcutaneous cable, wherein the front end fixing ring surrounds a crystalline lens, the support bracket is an annular vertical bracket which plays a role in supporting, a display screen and a control chip are arranged on the vertical bracket, the display screen is arranged in the horizontal symmetry direction of the front end fixing ring, the control chip is arranged on one side close to the skin, and the eyeball-crossing interface is connected with the vertical bracket and externally connected with the subcutaneous cable.
Preferably, the support bracket further comprises an annular horizontal bracket, the horizontal bracket and the vertical bracket are detachably connected, a display screen and a control chip are arranged on the horizontal bracket, and the eyeball-crossing interface is connected with the horizontal bracket.
Preferably, the front fixation ring surrounds the lens and is coupled to the interior of the eye by a fixation point.
Preferably, the front end fixing ring, the horizontal support and the vertical support are respectively implanted into the eyeball to be coupled internally.
Preferably, the control chip is arranged on the inner side surface of the eyeball on the horizontal bracket, spans the eyeball interface and the subcutaneous cable to the outside of the eyeball, and the interface is fixed on the head.
Preferably, the support bracket is made of semi-flexible material and is externally wrapped with special biocompatible material.
The utility model has the beneficial effects that: the utility model adopts a flat and soft structure, has the characteristic of detachability, adopts special biocompatible materials for wrapping, prolongs the service life of the device by the built-in chip and externally connecting the cable, has small damage on the implantation mode and is effective for a long time on biocompatibility.
