Problems solved by technology

But its disadvantages are: the button battery contains substances harmful to the human body, it is obviously inappropriate to stay in the human body for a long time, and when the battery is exhausted, it is more troublesome to replace the battery
"Its shortcoming is: 1. Adopt CCD camera as imaging device, 2. Self-focusing lens (namely gradient refractive index lens) does not consider shortening focal length, realizes seamless joint with CCD, so this system is only to a certain extent Miniaturization has been achieved, but for the needs of the camera in the eye of the visual prosthesis, the system is obviously too large to be implanted
And the system does not take into account the power supply design part

Embodiment Construction

[0017] Such as figure 1 As shown, the intraocular camera for visual prosthesis of the present invention includes: a gradient index lens 1 , a CMOS image sensor 2 , and a ring-shaped solar cell 3 . The gradient index lens 1 and the CMOS image sensor 2 are seamlessly connected, and the annular solar cell 3 completely wraps the gradient index lens 1 and the CMOS image sensor 2 inside, and the annular solar cell 3 is connected with the CMOS image sensor 2, forming a CMOS image sensor 2 Provide a stable working voltage.

[0018] Such as figure 2 As shown, the diameter of the gradient index lens 1 is between 0.35mm-0.6mm, and the diagonal size of the CMOS image sensor 2 is between 0.35mm-0.6mm, so that the two dimensions are exactly the same, seamlessly joined together, and the ring-shaped solar energy The inner diameter of the battery 3 is between 0.35mm and 0.6mm, which is exactly the same as the diameter of the gradient index lens 1 and the size of the diagonal of the CMOS ima...

Abstract

An intra-ocular camera head for artificial visual body features that a gradient index lens and CMOS image sensor are connected in seamless mode, and fully wrapped by an annular solar cell for supplying electric power to them. Its advantages are small axial size and no need of battery.

Description

technical field [0001] The invention relates to a device in the technical field of medical equipment, in particular to an intraocular camera for visual prosthesis. Background technique [0002] In recent years, many camera systems using solid-state imaging elements have been developed, which can collect image information in real time and are widely used in medical treatment, monitoring, security, etc. However, in order to meet the needs of various applications, they usually have high pixels and high resolution, complex functions, large size, and high power consumption, which cannot meet the requirements of visual prostheses. [0003] Existing camera systems usually use common lenses as optical lenses, which have a long focal length and large size, are difficult to process, are inconvenient to implant, and have high production costs. [0004] At present, button batteries are usually used as power sources in miniature imaging devices, which are small in size and easy to impla...
