[0041] The transmission coil 12 of the coil base 1 of the present invention is used to receive external signals and transmit the signals to the integrated package 2. The silicone sheet cover 11 of the coil base 1 is made of biocompatible silicone (such as American nusil silicone) and is used to encapsulate the transmission coil 12 to isolate the transmission coil 12 from the body fluids in the human body, protect the normal operation of the transmission coil 12, and extend its service life. At the same time, the silicone sheet cover 11 is set to match the shape of the eyeball, that is, it is generally in the shape of an arc surface, so that the silicone sheet cover 11 is completely attached to the eyeball to ensure a stable installation; in one embodiment, the two ends of the silicone sheet cover 11 of the coil base 1 are respectively connected to a bandage 4, the two bandages 4 are fitted to each other, so that the tail of one bandage 4 is close to the head of the other bandage 4, and the two bandages 4 are connected head to tail, such as by suturing with surgical thread, bonding with medical glue or tying the two bandages 4 to each other, and then the two bandages 4 and the silicone sheet cover 11 are together arranged into an arc shape that can completely fit the eyeball, so as to be stably fixed on the eyeball. In another embodiment, the two ends of the silicone sheet cover 11 of the coil base 1 are connected by a bandage 4, that is, the two ends of the silicone sheet cover 11 are correspondingly connected to the two ends of the same bandage 4, so that the silicone sheet cover 11 and a bandage 4 are arranged into a circular ring shape matching the shape of the eyeball, so as to be fixed on the eyeball.

[0042] Furthermore, the radius of the silicone sheet cover 11 of the coil substrate 1 is 13 mm to 15 mm, and the curvature of the silicone sheet cover 11 is 130° to 150° (i.e. Figure 2 The curvature between the two ends of the generally arc-shaped silicone sheet sleeve 11 shown in the figure is adapted to the size of the human eyeball, and the length of the bandage 4 is 50 mm to 60 mm (i.e. Figure 2 The width of the bandage 4 is 2.5 mm to 3.5 mm (i.e. Figure 4 The width of the bandage 4 in the left and right direction shown in the figure is fixed to adapt to the size of the human eyeball.

[0043] The integrated package 2 of the present invention is used to convert the received signal and transmit it to the neural electrode 3. The silicone tube sleeve 21 of the integrated package 2 is made of biocompatible silicone (such as American nusil silicone), which is used to encapsulate the titanium tube to isolate the titanium tube and the electronic devices inside from the body fluids in the human body, protect the normal operation of the electronic devices, and extend the service life. At the same time, the titanium tube of the integrated package 2 is generally cylindrical, which includes a titanium tube body and a titanium cover covered on the titanium tube body, so that the titanium tube has a certain mechanical support to maintain the cylindrical shape under the internal pressure of the eyeball and protect the internal electronic devices. A substrate is provided in the titanium tube, which can be a ceramic substrate, and an IC chip is provided on the substrate. The transmission coil 12 of the coil base 1 and the electrode plate 32 of the neural electrode 3 are both connected to the IC chip on the substrate to transmit signals, that is, receive signals from the transmission coil 12 and transmit them to the neural electrode 3. Furthermore, the silicone sleeve 21 of the integrated packaging body 2 is cylindrical, the diameter of the silicone sleeve 21 is 4.5 mm to 6.5 mm, and the height of the silicone sleeve 21 is 2 mm to 3 mm, so as to match the shape and size of the titanium tube to achieve packaging.

[0044] The electrode plate 32 of the neural electrode 3 of the present invention is used to receive electrical signals and apply the electrical signals to the retina of the eyeball. The silicone arc sleeve 31 of the neural electrode 3 is made of biocompatible silicone (such as American nusil silicone), which is used to encapsulate the electrode plate 32 to isolate the electrode plate 32 from the body fluids in the human body, protect the normal operation of the electrode plate 32, and extend the service life. The silicone arc sleeve 31 is generally in the shape of a strip arc, especially the end of the silicone arc sleeve 31 away from the integrated packaging body 2 matches the shape of the eyeball, that is, consistent with the curvature of the eyeball. Preferably, the arc radius of the end of the silicone arc sleeve 31 away from the integrated packaging body 2 is 13mm~15mm, so that the silicone arc sleeve 31 is tightly sealed and fits the eyeball, and then the stimulation part 321 of the electrode plate 32 located in the groove 311 of the silicone arc sleeve 31 is sealed between the silicone arc sleeve 31 and the eyeball and directly contacts the retina, thereby extending the service life. The stimulation part 321 at the end of the electrode plate 32 of the neural electrode 3 is a plurality of stimulation points arranged in a matrix.

[0045] Further, such as Fig.11As shown, the transmission coil 12 includes an energy coil 121 and a data coil 122, and the energy coil 121 is evenly spaced outside the data coil 122, and the energy coil 121 and the data coil 122 are electrically connected to the substrate respectively. Specifically, the energy coil 121 and the data coil 122 are both gold coils, and the silicone sheet cover 11 is integrally injection molded on the energy coil 121 and the data coil 122. The energy coil 121 and the data coil 122 are equally spaced concentric long circular rings, and the two are not connected to each other. The energy coil 121 and the data coil 122 are connected to the substrate of the integrated package 2 through the lead-out welding points. Preferably, the spacing between the energy coil 121 and the data coil 122 is 0.1mm~0.3mm, which saves space and can give full play to their respective functions without interfering with each other.

[0046] Further, such as Figure 1 and Figure 6 As shown, the two sides of the silicone sheet cover 11 of the coil base 1 are symmetrically provided with multiple pairs of surgical thread holes 5, which are convenient for doctors to insert and fix surgical threads during surgery, so as to firmly fix the present invention on the eyeball. The curvature of the surgical thread holes 5 is consistent with the curvature of the silicone sheet cover 11, that is, it is consistent with the curvature of the eyeball, which is convenient for close fit with the eyeball to facilitate firm fixation. Among them, the surgical thread holes 5 can be three pairs, and one pair is provided at each end of the silicone sheet cover 11 of the coil base 1. A pair of holes are arranged in the middle corresponding to the ends of the integrated package body 2 to facilitate fixation. Of course, other numbers can be arranged according to the surgical needs of various patients, and there is no limitation on this. The surgical thread hole 5 is made of silicone with biocompatibility, which can be integrally formed with the silicone sheet cover 11 of the coil substrate 1, or they can be separately formed and then fixedly connected. Preferably, the outer diameter of the surgical thread hole 5 is 2 mm, and the inner diameter of the surgical thread hole 5 is 0.8 mm, which is conducive to the threading and fixation of the surgical thread and reduces the occupied space.

[0047] Further, such as Figure 1 , Figure 5 and Fig.10As shown, the silicone arc sleeve 31 of the nerve electrode 3 gradually becomes thinner from the end connected to the integrated packaging body 2 to the end away from the integrated packaging body 2, that is, the thickness of the silicone arc sleeve 31 at the end connected to the integrated packaging body 2 is thicker, so that the silicone arc sleeve 31 of the nerve electrode 3 and the silicone tube sleeve 21 of the integrated packaging body 2 have a larger bonding area and a stronger bonding, and the thickness gradually becomes thinner toward the end away from the integrated packaging body 2, so that the silicone arc sleeve 31 does not produce a heavy sense of pressure on the eyeball, improves the flexibility and smoothness of the silicone arc sleeve 31, and thus improves the patient's comfort, and is easy for doctors to implant and easy to operate. Preferably, the thickness of the end of the silicone arc sleeve 31 connected to the integrated packaging body 2 is 1.3mm~1.6mm, and the thickness of the end of the silicone arc sleeve 31 away from the integrated packaging body 2 is 0.4mm~0.6mm.

[0048] Further, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Fig. 9 As shown, a plurality of recesses 312 are provided at intervals on the side of the silicone arc sleeve 31 of the nerve electrode 3 facing away from the eyeball to eliminate electrode stress, improve the flexibility of the electrode plate 32, and reduce the weight and friction between the nerve electrode 3 and the eyeball. Preferably, the recesses 312 are rectangular, and there are four recesses 312. Of course, the recesses 312 can also be set to other suitable numbers, which are not limited here.

[0049] Further, such as Figures 6 to 8 , Fig.10 As shown, the nerve electrode 3 is penetrated by a titanium nail hole 33, and a titanium nail 6 which can be fixed to the eyeball is penetrated in the titanium nail hole 33, so as to cooperate with the bandage 4 and the surgical thread hole 5 to more firmly fix the present invention to the eyeball, wherein the diameter of the titanium nail hole 33 is 0.5mm to 0.6mm.

[0050] The silicone-encapsulated artificial retina implant of the present invention can be applied to the left eye, the right eye, or both eyes at the same time through two implants. In the first embodiment, as Figures 1 to 5 , which shows a schematic structural diagram of each viewing angle of the silicone-encapsulated artificial retinal implant of the present invention when applied to the right eye, that is, the neural electrode 3 is connected to the side wall on the left side of the integrated package 2. In the second embodiment, as Figures 6 to 10, which shows a schematic diagram of the structure of the silicone-encapsulated artificial retina implant of the present invention at various viewing angles when applied to the left eye, that is, the neural electrode 3 is connected to the side wall on the right side of the integrated package 2. The present invention is based on the overall design of the human eyeball, has good smoothness and flexibility, can standardize the implantation steps and speed of the artificial retina, is convenient for doctors to operate, is easy to operate, causes little damage to the microstructure of the retina, is convenient to protect patients, and avoids secondary damage to patients.

At this time, the blind person will wear an external receiving device used in conjunction with the silicone-encapsulated artificial retinal implant of the present invention, such as glasses. The external receiving device is provided with a miniature camera, which can simultaneously record video and perform intelligent processing on the video. The processed data is wirelessly transmitted to the coil substrate 1, and the data coil 122 of the coil substrate 1 receives the data and transmits the data to the IC chip on the substrate in the integrated package 2, and powers it through the energy coil 121. After the chip is decoded, the electrical signal is transmitted through the stimulation part 321 arranged in an array at the end of the electrode plate 32 of the neural electrode 3, so as to stimulate the retinal nerve cells through the stimulation part 321, and then transmit the signal to the human brain, so that the blind person can feel the recorded video data.
