Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The present invention relates to an optic nerve protection device based on a microwire array electrode, which is intended to protect the optic nerve by using electrical stimulation signals in a non-invasive or minimally invasive manner. The following is an implementation method of the device.

[0019] Combination Figure 1 , Figure 2 The optic nerve protection device includes a wearable module, a power supply module, an environment acquisition module, a signal processing module and a microwire array electrode 7, wherein the power supply module is used to provide power to the signal processing module and the environment acquisition module, the wearable module is used to fix the device on the recipient, and after the microwire array electrode 7 is implanted in the optic chiasm, the position of the electrode is ensured not to shift, the environment acquisition module is used to collect spectral information of external ambient light, and transmit the spectral information to the signal processing module, the signal processing module receives the spectral information to generate an electrical stimulation signal that meets the patient's condition, and transmits the electrical stimulation signal to the microwire array electrode 7, the microwire array electrode 7 receives the electrical stimulation signal and acts on the optic nerve axons and synapses, thereby performing protective electrical stimulation.

[0020] In addition, the signal processing module is also used to control the power supply module to achieve the master control of the electrical stimulation device.

[0021] The technical effects of the optic nerve protection device include: using the ambient light data collected by the environment acquisition module to generate personalized electrical stimulation signals according to the patient's optic nerve damage, combined with the precise implantation of the microwire array electrode 7, the electrical stimulation parameters can be flexibly adjusted according to the conditions of different patients, providing customized treatment effects, thereby effectively protecting and repairing the optic nerve axons and synapses.

[0022] The following describes in detail the composition of the wearable module, power supply module, environment acquisition module, signal processing module and microwire array electrode 7.

[0023] The wearable module includes a shell 1 and a headgear 2. The shell 1 is used to install a power supply module, an environment acquisition module, a signal processing module and a microwire array electrode 7. The headgear 2 is used to fix the shell 1 on the head of the recipient to ensure that the position of the shell 1 is stable.

[0024] The shell 1 is also used to physically protect the internal functional modules (such as the power supply module, the signal processing module, and the environment acquisition module) to avoid being affected by adverse factors such as collision, extrusion, dust, and water vapor. The material of the shell 1 is selected from medical plastics and other lightweight, strong and biocompatible materials. The surface of the shell 1 can be specially treated with frosting, waterproofing, anti-static treatment, etc.

[0025] The headgear 2 is mainly used to help reduce the risk of displacement of the microwire array electrode 7 caused by the patient's daily activities, ensure the stability of the relative position of the electrode and the optic chiasm, so as to maintain the accuracy and continuity of the electrical stimulation signal. The material of the headgear 2 is soft, breathable, and elastic (such as cotton or fabric containing elastic fibers). The tightness can be adjusted by means of Velcro, buckles, etc. to adapt to different patient head sizes.

[0026] The power supply module includes a switch 3, a power module, a charging module, and a power detection module. The power supply module is responsible for providing power support to ensure the normal operation of the device and to issue a warning in time when the power is low.

[0027] The switch 3 is connected to the housing 1, and the switch 3 directly controls the start and stop of the power module, thereby controlling the switch 3 function of the electrical stimulation device. When the switch 3 is turned on, the electrical stimulation device starts working and starts the functions of each module.

[0028] The power module includes two batteries, one is a normal power supply battery and the other is a power-off non-loss battery. The two batteries are used to provide stable current so that the device can run for a long time. The power module is connected to the power detection module and the charging module to ensure continuous power supply and power monitoring of the battery.

[0029] Among them, the normal power supply battery ensures the stable operation of the regular functions of the equipment, provides power for the continuous output of stimulation protection signals for the optic chiasm, and does not lose the battery in the event of a power outage. When the battery is switched or the normal power supply battery is exhausted, it provides key memory support for the microcontroller, saves important parameters of the equipment, and can intermittently output stimulation signals to avoid sudden power outages that cause the equipment to completely stop working.

[0030] The charging module is connected to the power module to realize the charging and power supply functions. The charging module includes a charging interface 4 and an indicator light arranged on the shell 1. The external 5V power supply charges the two batteries through the charging interface 4. The indicator light on the shell 1 can display the charging progress, which is convenient for patients to quickly charge the device in various environments.

[0031] The power detection module is used to measure the battery voltage in real time. When it is detected that the battery is too low or full, the information is displayed on the doctor's mobile phone APP through the signal processing module, or an alarm is given through the prompt module set on the shell 1.

[0032] The environment acquisition module is used to collect external ambient light information and transmit the ambient light information to the main control module for further processing to generate a suitable electrical stimulation signal.

[0033] The environment acquisition module is located at the front end of the shell 1 and is connected to the main control module through the IIC communication interface. It is used to collect external ambient light information and transmit the ambient light information to the main control module through the internal circuit module. The main control module generates a corresponding analog visual signal based on the environmental data. The environment acquisition module cooperates with the light source input protection lens 5 to form accurate environmental data by collecting light signals.

[0034] The environment acquisition module includes an acquisition chip. The acquisition chip is AS7341, which has 11 measurement channels and a spectral response range of approximately 350nm-1000nm.

[0035] The functional characteristics of the environment acquisition module are to provide multi-channel precise measurement and wide spectrum response, which can capture the intensity information of ambient light in each band; the high sensitivity design can detect extremely weak light changes and light flicker; it can quantitatively analyze the color of objects and combine algorithms to infer the distance of objects; non-contact light detection can track the light intensity and color changes of moving objects in real time.

[0036] The environment acquisition module also includes a light source input protection lens 5, which is used to protect the sensor (optical structure or sensitive element) on the environment acquisition module from being damaged by strong light, foreign matter, etc., to ensure that the environment acquisition module can normally receive the ambient light signal.

[0037] The material of the light source input protection lens 5 is selected from optical glass or transparent polymer material with high transparency, good optical performance and certain wear resistance, which can not only ensure that light can pass through to meet the requirements of the device, but also withstand a certain degree of impact and friction.

[0038] The signal processing module includes a main control module, a stimulation protection module and a channel selection output port 6. The main control module is responsible for processing the signal from the environment acquisition module, and generating an electrical stimulation signal through the stimulation protection module, which is finally output to the microwire array electrode 7 through the channel selection output port 6.

[0039] The main control module includes the main control chip U1, ADC, GPIO port, integrated Bluetooth chip, IIC communication interface, SPI communication interface, and data storage module.

[0040] Among them, ADC is used to detect and read the battery charge value, the GPIO port is used to execute the configuration function and monitoring of the analog-to-digital conversion chip, the integrated Bluetooth chip is used to realize communication with the mobile phone APP, the IIC communication interface is used to receive data from the environment acquisition module to realize high-speed interaction and integrated processing, the SPI communication interface is used to output the stimulation protection signal to the subsequent stimulation electrode module, and the data storage module internally stores a large amount of normal visual signal data formed by the collection and analysis of visual signals of healthy people.

[0041] During treatment, according to the patient's specific conditions (degree of optic nerve damage, remaining vision, etc.), the corresponding normal visual signal template is retrieved from the data storage module and personalized adjustments are made.

[0042] The main control module is responsible for receiving the spectral information from the environment acquisition module and generating simulated visual signals according to the normal visual signal data in the device database. The main control module is connected to the stimulation protection module through the SPI interface and outputs the processed signal to the microwire array electrode 7 to perform the electrical stimulation task.

[0043] The stimulation protection module includes a DAC chip, an operational amplifier and a channel selection output port 6 .

[0044] The DAC chip converts the digital signal from the main control module into an analog signal, and further processes the signal through a precision operational amplifier to ensure the purity and stability of the signal. The processed signal is output through the channel selection output port 6 and accurately transmitted to the microwire array electrode 7 to ensure that the electrical stimulation signal can cover multiple neural targets of the optic chiasm.

[0045] The channel selection output port 6 is connected to the stimulation protection module, allowing the position of the stimulation channel to be switched through programming. The channel selection output port 6 matches the signal output of the stimulation protection module to ensure that the output signal can be amplified and accurately transmitted to the microwire array electrode 7. The doctor can accurately control the device through the mobile phone APP, select the appropriate electrode position, and enhance the stimulation effect.

[0046] The microwire array electrode 7 is implanted in the optic chiasm, connected to the stimulation protection module, receives the electrical stimulation signal sent by the stimulation protection module, and acts precisely on the optic nerve axons and synapses.

[0047] The electrode wires of the microwire array electrode 7 are made of materials such as platinum-iridium alloy and titanium alloy, have good biocompatibility, and are tiny in diameter (20 to 100 microns), ensuring minimal damage to surrounding tissues.

[0048] On the other hand, since the microwire array electrode 7 is connected to the signal processing module, when the device falls or is pulled by external force, if the connection between the microwire array electrode 7 and the signal processing module cannot be disconnected in time and safely, it may cause damage to the patient's brain.

[0049] To solve this problem, combined with Figure 3 The wiring harness terminal female head 71 of the microwire array electrode 7 and the wiring harness terminal male head 72 of the signal processing module are connected by a spring locking mechanism. When the device falls or is pulled by external force, the spring locking mechanism can pre-disconnect the connection between the wiring harness terminal female head 71 and the wiring harness terminal male head 72, thereby preventing the force applied to the device when it falls or is pulled from being transmitted to the microwire array electrode 7.

[0050] Figure 4 , Figure 5 , Figure 6 The specific structure of the spring lock mechanism is shown, and the spring lock mechanism includes a lock male head 81, a lock female head 82, a latch pin 83 and a spring 84.

[0051] Among them, the locking male connector 81 is fixedly connected to the wiring harness terminal male connector 72 of the signal processing module, or the two are an integrated part, and the locking female connector 82 is fixedly connected to the wiring harness terminal female connector 71 of the microwire array electrode 7, or the two are an integrated part, and the locking male connector 81 and the locking female connector 82 are plugged in, so that the wiring harness terminal male connector 72 and the wiring harness terminal female connector 71 are firmly connected, thereby transmitting electrical signals.

[0052] The spring 84 is arranged between the lock male head 81 and the lock female head 82, and the spring 84 is pre-compressed. The latch 83 passes through and connects the lock male head 81 and the lock female head 82, and the spring 84 is in a compressed state.

[0053] When the device falls or is pulled by external force, the latch 83 is pulled out, and the spring 84 is released. The male lock head 81 and the female lock head 82 are separated by the elastic force of the spring 84, thereby separating the male wire harness terminal 72 and the female wire harness terminal 71.

[0054] In order to achieve the technical effect that the pin 83 is pre-pulled out when the device falls or is pulled by external force, the pin 83 is connected to the housing 1 via a traction line 831, and the length of the traction line 831 is less than the length of the harness connecting the signal processing module and the male connector 72 of the harness terminal. Therefore, when the device falls or is pulled by external force, the traction line 831 is first straightened, and then the pin 83 is pulled out, and then the harness connecting the signal processing module and the male connector 72 of the harness terminal is straightened. At this time, the male connector 72 of the harness terminal and the female connector 71 of the harness terminal have been separated, thereby preventing the force from being transmitted to the microwire array electrode 7.

[0055] Specifically, a blind hole 821 is provided on the side of the lock female head 82 facing the lock male head 81, and a through hole 811 is provided on the side of the lock male head 81 facing the lock female head 82. A protruding positioning column 812 is provided inside the through hole 811, and both ends of the positioning column 812 extend radially outward. One end of the positioning column 812 is close to the blind hole 821, thereby forming a positioning end 813 for inserting into the blind hole 821, and the other end of the positioning column 812 is away from the blind hole 821, thereby forming an active end 814 for driving the positioning end 813 to extend and retract inside the through hole 811.

[0056] The spring 84 is arranged between the positioning column 812 and the through hole 811, and one end of the spring 84 abuts against the lock male head 81, and the other end of the spring 84 abuts against the active end 814. After the spring 84 is pre-compressed, the positioning end 813 extends from the inside of the through hole 811, so that it can be inserted into the inside of the blind hole 821. One side of the positioning end 813 is provided with a socket 815 for the pin 83 to be inserted, and the lock female head 82 is provided with an opening 822 that passes through the lock female head 82 and exposes the socket 815. When the positioning end 813 is inserted into the inside of the blind hole 821, and the pin 83 passes through the opening 822 and is inserted into the inside of the socket 815, the lock male head 81 and the lock female head 82 are plugged in.

[0057] refer to Figure 7 When the spring 84 is extended, the active end 814 moves in a direction away from the lock female head 82, and the positioning column 812 slides inside the through hole 811 until the positioning end 813 retracts into the through hole 811. At this time, the lock male head 81 is separated from the lock female head 82.

The protection scope of the present invention is defined by the claims.
