[0003] At present, implantable neurostimulators are mainly powered by built-in energy storage units, which usually use rechargeable batteries for power supply. Wireless charging technology is used to achieve wireless charging of the built-in energy storage units of implantable neurostimulators, avoiding the pain of frequent battery replacement for patients. However, since implantable neurostimulators need to be implanted in the human body for a long time, and battery aging is an inevitable process, when implantable neurostimulators are implanted for a long time, the chemical reaction efficiency inside the aging battery decreases, causing the battery to be unable to provide enough power to maintain the normal operation of the implantable neurostimulator. In addition, aging batteries have a high risk of thermal runaway, and are prone to overheating, combustion, and even explosion, which damages the health of patients and poses a high safety risk.

DETAILED DESCRIPTION

[0058] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0059] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present application in a schematic manner. Therefore, the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0060] To facilitate the understanding of the technical solutions provided by the present application, the relevant terms in the present application are explained before the specific embodiments, as follows:

[0061] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0062] See also Figure 1 , shown is a schematic diagram of the structure of an existing implantable neural stimulator.

[0063] like Figure 1 As shown, the existing implantable neurostimulator includes: a wireless energy receiving unit, a voltage stabilizing unit, a wireless communication unit, a control unit, an energy storage unit, a voltage conversion unit and a pulse output unit; wherein,

[0064] The wireless energy receiving unit is electrically connected to the voltage stabilizing unit and the energy storage unit, respectively, to supply power to the voltage stabilizing unit and the energy storage unit;

[0065] The voltage stabilizing unit is electrically connected to the control unit to provide stable power supply to the control unit;

[0066] The energy storage unit is electrically connected to the control unit and the voltage conversion unit respectively;

[0067] The voltage conversion unit is electrically connected to the pulse output unit to supply power to the pulse output unit;

[0068] The wireless communication unit is electrically connected to the control unit so as to enable the control unit to communicate with an external device;

[0069] The control unit is communicatively connected to the pulse output unit, and is used to receive an external control signal, and based on the external control signal, generates a corresponding first pulse output signal to control the pulse output unit to output an electrical pulse corresponding to the first pulse output signal.

[0070] Depend on Figure 1 It can be known that the existing implantable neurostimulator receives an external electromagnetic signal through a wireless energy receiving unit, converts the external electromagnetic signal into a first electrical signal, and supplies power to the voltage stabilizing unit and the energy storage unit respectively; after receiving the first electrical signal, the voltage stabilizing unit reduces the voltage of the first electrical signal to achieve stable power supply to the control unit; the energy storage unit receives and stores the first electrical signal;

[0071] When the existing implantable neurostimulator is in working state and has no external power supply, the energy storage unit transmits the electric energy stored therein to the control unit to supply power to the control unit; the wireless communication unit receives and sends an external control signal to the control unit, and the control unit generates a first pulse output signal based on the external control signal and sends the first pulse output signal to the pulse output unit; and the energy storage unit transmits the electric energy stored therein to the voltage conversion unit, and the voltage conversion unit performs voltage conversion on the electric energy to provide the pulse output unit with the required rated input voltage, and the pulse output unit outputs electric pulses accordingly based on the first pulse output signal;

[0072] As can be seen from the above, the existing implantable neurostimulators are equipped with an energy storage unit and a voltage conversion unit configured with the energy storage unit. When supplying energy, the voltage conversion unit needs to be used to perform a secondary voltage conversion on the electric energy stored in the energy storage unit (the voltage conversion is usually to boost the electric energy output by the energy storage unit so that it meets the high voltage input required by the pulse output unit), which reduces the energy supply efficiency of the pulse output unit and increases the energy supply loss. In addition, configuring the energy storage unit and the voltage conversion unit at the same time not only increases the overall volume of the implantable neurostimulator, but also has low human implant friendliness, and the energy storage unit has the risk of leakage and aging, making it difficult to ensure the patient's safety.

[0073] Based on the defects of the above-mentioned prior art, the following embodiments of the present application provide a stimulator wireless power supply method, which receives a first electromagnetic signal by using an energy receiving module and converts the first electromagnetic signal into an electrical signal; and obtains treatment parameter information based on the first electromagnetic signal by using a stimulator signal processing module, and sends the treatment parameter information to a main control module; and obtains a preset voltage threshold corresponding to the treatment parameter information and extracts a voltage value of the electrical signal by using the main control module, and determines and sends control feedback information to the stimulator signal processing module based on the voltage value and the preset voltage threshold; processes the second electromagnetic signal by using the stimulator signal processing module based on the control feedback information, so that the second electromagnetic signal contains the control feedback information, and the energy receiving module transmits the second electromagnetic signal to the outside, so that the external power supply device adjusts its transmission power according to the control feedback information in the second electromagnetic signal, so as to provide the stimulator with an electromagnetic signal corresponding to the treatment parameter information in real time, and the method can enable the stimulator to output an electric pulse corresponding to the treatment parameter information, thereby realizing long-term and stable wireless power supply to the stimulator without setting an energy storage unit in the stimulator, thereby improving the safety of the stimulator.

[0080] The pulse output module is electrically connected to the energy receiving module and is used to receive the electrical signal to output an electrical pulse corresponding to the pulse output signal.

[0081] Specifically, the energy receiving module 11 receives the first electromagnetic signal, converts the first electromagnetic signal into an electrical signal, and transmits the electrical signal to the voltage stabilizing module 12 and the pulse output module 15 respectively; the voltage stabilizing module 12 reduces the voltage of the received electrical signal, and provides the reduced voltage electrical signal to the main control module 14 to provide stable power supply to the main control module 14; the stimulator signal processing module 13 extracts a sampled electromagnetic signal from the first electromagnetic signal, obtains treatment parameter information based on the sampled electromagnetic signal, and sends the treatment parameter information to the main control module 14; the main control module 14 generates a corresponding pulse output signal based on the treatment parameter information, and sends the pulse output signal to the pulse output module 15; the pulse output module 15 receives the electrical signal, and based on the pulse output signal, outputs an electrical pulse corresponding to the pulse output signal; and the main control module 14 extracts the voltage value of the electrical signal, determines the regulation feedback information based on the voltage value and a preset voltage threshold, and sends the regulation feedback information to the stimulator signal processing module 13; the stimulator signal processing module 13 processes the second electromagnetic signal based on the regulation feedback information so that the second electromagnetic signal contains the regulation feedback information; the energy receiving module 11 emits a second electromagnetic signal containing the regulation feedback information, so that the external energy supply device can adjust its transmission power in real time based on the regulation feedback information in the second electromagnetic signal.

[0087] Exemplarily, the wireless communication module 16 includes: a Bluetooth chip and / or a WiFi chip, etc.

[0088] It should be noted that since the modem unit is mainly responsible for receiving the modulated signal and extracting the original information of the modulated signal through the demodulation process, its circuit mainly includes components such as modems, filters and amplifiers. Such components are small in size and can be compactly designed to reduce the space occupied by hardware; while the wireless communication unit needs to modulate, send, receive and demodulate the signal, and its circuit includes a wireless transmitter and receiver, requiring components such as antennas, radio frequency amplifiers and modems. Such components are large in size and occupy a large hardware space. Therefore, when the modem unit is included in the stimulator, its overall volume is smaller than the overall volume of the stimulator including the wireless communication module.
