Specific embodiment
In order to facilitate the understanding of the present invention, it is described below in conjunction with the accompanying drawings：
As shown in Figs 1-4, the present invention provides a kind of retina prosthese with multiple stimulation components, including being implanted to
Stimulation component 1 inside eyeball tissue and the episcleral communication part 2 of eyeball tissue outer wall is arranged on, stimulates component 1 to be multiple,
Multiple stimulation components 1 are distributed in human body sclera macular area and its near zone, multiple shapes for stimulating component 1 according to eyeball macular area
Shape is distributed.
In general, organize macular area and near zone can be there are certain radian, in order to fully stimulate eye in human eyeball
Ball tissue, multiple retinas stimulate component 1 that can be distributed according to its construction features in cambered surface, component 1 are stimulated not only to only act upon Huang
On macular area, the region near macular area can also be stimulated.
Each multiple stimulating electrodes 4 that component 1 is stimulated to include substrate 3 and be arranged in substrate, communication part 2 include encapsulation
Body 21 and coupling coil 22, multiple stimulating electrodes 1 pass through communication group on eyewall and eyeball tissue outer wall by signal connecting line 71
Part 2 connects.
Since each stimulating electrode 1 is required for picking out signal connecting line 71, multiple stimulating electrodes are intended to pick out more
More signal connecting lines, when 71 quantity of signal connecting line is excessive, picking out the diameter of circuit will become larger, to people in implantation process
The wound of body can also increase, and in order to overcome this defect, each stimulate on component be additionally provided with second processing core in the present invention
Piece 5, second processing chip 5 and substrate 3 link together, and 5, second processing core is realized first and the connection of stimulating electrode 1, so
Circuit is picked out by the pad structure on second processing chip 5 afterwards, the first processing in last and eyeball external communication component
Chip (not marked in figure) is connected, and need not pick out connecting line for every stimulating electrode, greatly reduce the number of connecting line
Amount.
Multiple signal connecting lines 71 stimulated on component 1 are gathered together to form a winding displacement 7, and the winding displacement 7 is out of eyeball
Portion is connected on the episcleral communication part 2 of eyeball tissue outer wall.
The cross section of winding displacement 7 can be in " flat ", and such winding displacement is also " flat to its wound when through wall of eyeball
Shape ", the wound of this " flat " are easier to heal.In addition, winding displacement can also become one by way of spiral rotating
Root " it is compact " signal connecting line, the signal connecting line diameter is small, and with certain elasticity, during operation to wound wound
It is small, and be not easily broken.
In order to avoid tissue fluid penetrates into component internal is stimulated to cause to damage to the second chip 5, on each stimulation component
Second processing chip on be also covered with chip package lid 6, which seals second processing chip 5, can so keep away
Exempt from tissue fluid penetrate into stimulate component internal chip is caused to damage, in general, chip package cover be provided with metal feedback
Logical structure, metal feed through structures inside are connected with pad, and outside is picked out by connecting line, and sealing effect is good.
In stimulating course, since stimulated zone is different, site of action tissue nerve has differences, multiple stimulations
The density of stimulating electrode on component is arranged to not exactly the same, and specific apparent size can also be according to practical function region
Adjustment.
Packaging body and coupling coil on the communication part outside eyeball are wrapped with one layer of silica gel, and communication part passes through
Connect band 23 forms a closed loop and is fixed on human eyeball's tissue, is set in communication part 2 or 23 position of connect band seamed
Heal up 24, the suture mouth 24 is used for retina prosthese being sewn on eyeball tissue in implantation.
Above example is only presently preferred embodiments of the present invention, not limiting the present invention, it is noted that
Any modification, equivalent substitution, improvement and etc. made within the spirit and principles of the invention are in protection scope of the present invention
Within.
