Description

Technical Field

[0001] This invention relates to the field of medical technology, and in particular to a control system, method, device and storage medium for medical implantable devices. Background Technology

[0002] In recent years, the market size of implantable medical devices has shown a year-on-year growth trend, benefiting patients. Active implantable medical devices include cardiac pacemakers (cardiac pacemakers, defibrillators, etc.), total artificial hearts, spinal cord stimulators (SCS), vagus nerve stimulators (VNS), brain pacemakers (DBS), cochlear implants, etc. The basic principle of these devices is mostly to stimulate nerve or muscle tissue by generating electrical pulse signals. Active implantable devices all require power to ensure their normal operation, mainly through built-in battery power. However, this requires regular battery maintenance, and removing the implant undoubtedly increases the risk to the patient. Furthermore, the inability to control and communicate with the implanted device in real time after implantation limits its current functionality. Using electromagnetic waves for power supply, control, and communication poses the following risks: wireless power supply electromagnetic waves can cause electromagnetic interference to the device, affecting its stability; simultaneously, electromagnetic waves attenuate significantly within the human body, and emitting high-power electromagnetic waves for power supply also poses potential risks to the human body. Sound waves, as another form of wave, also carry energy and information during propagation due to their wave nature. Ultrasound has been widely used in industrial testing and biomedical engineering due to its portability, efficiency, and safety. Therefore, ultrasound can be safely used as a means of control, communication, and power supply for medical implants.

[0003] Currently, focused ultrasound probes are typically used to emit ultrasonic waves to power and control a single device, which cannot achieve multi-functional control or simultaneous control of multiple devices. Summary of the Invention

[0004] The purpose of this invention is to provide a control system, method, device, and storage medium for medical implantable devices.

[0005] This invention provides a control system for medical implantable devices, comprising: an external acoustic holographic phased array and at least one implantable device to be controlled, wirelessly connected to the external acoustic holographic phased array, wherein...

[0006] The external acoustic holographic phased array is used to construct a special sound field, emit ultrasonic waves to the implanted device, adjust different types of implanted devices located at different positions, locate and track the position of the implanted device in motion, perform spatial division multiplexing, and realize synchronous control of wireless power supply, wireless operation and wireless communication for the implanted devices at different positions.

[0007] The implanted device is used to receive ultrasonic control signals, set corresponding ultrasonic wireless signals, power its own device, control the triggering of its own device, and execute the derivative functions of its own device.

[0008] The form of the ultrasonic wireless signal depends on the different implanted devices and the different functions implemented by the implanted devices.

[0016] The position tracking unit is used to acquire the position of the distributed medical implantable devices. The spatial position of each implantable device is input into the system. If the position of the implantable device is unknown or not fixed, the position of each device is acquired by using an ultrasound imaging method. The ultrasound signal generator excites the ultrasound phased array probe and receives the scattered signals inside the human body. The imaging algorithm obtains the three-dimensional imaging result inside the human body and determines the spatial position of the implantable device relative to the ultrasound phased array probe, thereby realizing real-time tracking of the position of the implantable device.

[0017] An ultrasonic signal conversion unit is used to calculate and set the ultrasonic wireless signal form corresponding to the implanted device at different locations based on the sound field type, sound field intensity and sound field modulation method in the corresponding acoustic holography algorithm.

[0018] The result output unit is used to obtain the optimal phased array probe transmission parameter settings by iteratively optimizing the transmission parameters of the phased array through the algorithm. Then, the ultrasonic signal generator generates a corresponding driving electrical signal for each transmission unit according to the optimal transmission parameters. The ultrasonic phased array probe is electrically driven and transmits different control signals to the corresponding implanted device in a directional, fixed-point, end-to-end manner.

[0020] Preferably, both the first implantable device and the second device include:

[0021] An ultrasonic transducer is used to receive acoustic energy and convert it into an AC signal;

[0022] An ultrasonic signal demodulation module is used to demodulate the control or communication information carried by ultrasound, and to demodulate the AC signal into a DC signal;

[0023] The energy management and voltage regulation module is used to extract ultrasonic energy and stabilize the voltage, providing a stable power supply to the back-end load. At the same time, it converts control signals and communication signals into standard logic levels, realizing power supply, control, communication, and other derivative functions of the implanted device.

[0024] Preferably, the second implantable device further includes an ultrasonic signal modulation module for controlling the communication relationship between the implantable device and an external device, modulating the control signal into ultrasonic waves, which are then emitted by the ultrasonic transducer, received by the ultrasonic phased array probe, converted into digital signals by the ultrasonic signal receiver, and demodulated by the computing module or the external device.

[0025] This invention provides a control method for medical implantable devices, comprising:

[0026] An external acoustic holographic phased array and at least one implantable device to be controlled, which is wirelessly connected to the external acoustic holographic phased array;

[0027] A special sound field is constructed on the external acoustic holographic phased array to emit ultrasonic waves to the implanted device. Adjustments are made to different types of implanted devices located at different positions. The position of the implanted device in motion is located and tracked. Spatial division multiplexing is performed to realize synchronous control of wireless power supply, wireless operation and wireless communication for the implanted devices at different positions.

[0028] The device receives ultrasonic control signals from the implanted device, sets corresponding ultrasonic wireless signals, powers its own device, controls the triggering of its own device, and executes its own device's derivative functions.

[0029] The form of the ultrasonic wireless signal depends on the different implanted devices and the different functions implemented by the implanted devices.

[0030] Preferably, the implantable device to be controlled includes a first implantable device and a second implantable device; the first implantable device is unidirectionally connected to the external acoustic holographic phased array, and the second implantable device is bidirectionally connected to the external acoustic holographic phased array.

[0031] Preferably, the present invention provides a control method for medical implantable devices, further comprising:

[0032] Obtain the first positioning point of the signal emitted on the external acoustic holographic phased array;

[0033] Determine the second positioning point for receiving signals on different implanted devices;

[0034] Different types of sound waves are emitted from the first positioning point to the second positioning point at different locations in space to complete the reception of the correct signal at the preset position, thereby realizing the secure wireless power supply and data transmission within and outside the electromagnetic shielding range.

[0035] The present invention also provides a control device for a medical implantable device, including a memory and a processor.

[0042] Figure 2 This is a schematic diagram of the steps of the control method for medical implant devices according to an embodiment of the present invention. Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1

[0045] like Figure 1 As shown, the present invention provides a control system for medical implantable devices, comprising: an external acoustic holographic phased array and at least one implantable device to be controlled, wirelessly connected to the external acoustic holographic phased array, wherein...

[0046] The external acoustic holographic phased array is used to construct a special sound field, emit ultrasonic waves to the implanted device, adjust different types of implanted devices located at different positions, locate and track the position of the implanted device in motion, perform spatial division multiplexing, and realize synchronous control of wireless power supply, wireless operation and wireless communication for the implanted devices at different positions.

[0047] The implanted device is used to receive ultrasonic control signals, set corresponding ultrasonic wireless signals, power its own device, control the triggering of its own device, and execute the derivative functions of its own device; the control signals refer to various forms of ultrasonic waves, such as ultrasonic energy, electrical signals, etc.

[0048] The form of the ultrasonic wireless signal depends on the different implanted devices and the different functions implemented by the implanted devices.

[0049] The transmitting system mainly includes an acoustic holographic phased array, which contains a computing module, an ultrasonic signal generator, an ultrasonic signal receiver, and an ultrasonic phased array probe.

[0050] The aforementioned system is a distributed system, which is composed of many sub-devices interconnected through a network. Thanks to acoustic holography algorithms, a more advanced spatial division multiplexing (SDM) can be achieved, distinct from spatial multiplexing (multiple information transmission channels) in communication. This also includes functional spatial division multiplexing, the key points of which are: 1. A single ultrasonic transmitting device can achieve ultrasonic-based wireless power supply, wireless control, and wireless communication; 2. It can provide end-to-end functionality for different devices located in different locations.

[0051] The external acoustic holographic phased array includes: a computing module for calculating the transmission parameters of the external acoustic holographic phased array, running the computational application of the ultrasound imaging algorithm, and controlling the execution of the ultrasound signal generator; an ultrasound signal generator for generating electrical signals to drive the ultrasound phased array probe, adjusting the signal of each channel in the external acoustic holographic phased array according to the adjustment content, wherein the signal of each channel in the phased array is independently adjustable, and the adjustment content includes: center frequency, pulse intensity, pulse length, time delay, modulated signal intensity and signal phase for continuous wave mode, etc.; an ultrasound signal receiver for receiving the electrical signals of the ultrasound phased array probe, converting the analog electrical signals into digital signals, and transmitting them to the computing module for calculation; and an ultrasound phased array probe for directional, point-to-point, end-to-end transmission of ultrasonic energy and modulation signals to the corresponding implanted device when electrically driven.

[0052] Implantable devices that can utilize ultrasonic signals for power supply, control, and communication should include, in addition to their inherent functions, an ultrasonic transducer, an ultrasonic signal demodulation module, and an energy management and voltage regulation module. Implantable devices requiring bidirectional communication should also include an ultrasonic signal modulation module.

[0053] The main hardware system is described above. The system is compatible with external hardware and can work collaboratively in different application scenarios. For example, it can perform acoustic holographic calculations and ultrasound imaging using a more powerful external computer. The system is applicable to different ultrasound phased array probes, and the algorithm can intelligently adjust the acoustic holographic calculations according to different probes. The system can be adjusted for medical implants in different locations, allowing manual input of the coordinates of each device; it can also locate each implant through ultrasound imaging equipment and track moving devices, enabling control of the in-body robot and preventing the impact of patient movement. The system can be adjusted for different types of medical implants. As mentioned earlier, ultrasound-based implants should have additional ultrasound-related modules. However, depending on the specific functions of the implant, environmental limitations, etc., the performance, energy required, and control signal modes of the ultrasound-related modules equipped with the implant will vary. The external transmission device can be set with different energy intensities and modulation modes for different implants. With the characteristic of "space division and multi-purpose", it can operate devices in different locations at the same time; and different locations can realize different operating functions, breaking the traditional limitations and integrating wireless power supply, wireless control and wireless communication into one, so that a single transmitting device can realize these different functions.

[0054] The phased array used in this embodiment of the invention is applicable to the construction of three-dimensional sound fields using acoustic phased arrays or metamaterials. The method for constructing the three-dimensional sound field includes the following steps: initializing the acoustic holography algorithm according to the performance parameters of the transmitting device; constructing an initial sound field as a reference distribution for the three-dimensional sound field to be constructed; simulating the sound propagation process and propagating the target sound field backward to the transmitting plane; obtaining feedback information on the sound field distribution at the transmitting plane and calculating the transmission parameters of the transmitting plane; propagating the target sound field forward to the position of the initial sound field according to the transmission parameters of the transmitting plane, obtaining the forward propagation sound field distribution information, and determining whether the construction quality of the target sound field meets the preset requirements. If yes, the construction of the three-dimensional sound field is completed; if not, the target sound field is corrected according to the sound field distribution information obtained from the forward propagation and the reference distribution, and the corrected target sound field is propagated backward to the transmitting plane. Feedback information on the sound field distribution at the transmitting plane is obtained, and the transmission parameters of the transmitting plane are calculated until the transmission parameters meet the preset requirements.

[0055] Transmitting devices typically consist of a phased array of many small transmitting units, or are assisted by artificially designed metamaterials to emit sound waves. Different applications impose varying requirements on device size, power consumption, and cost (complexity). Considering the many unique properties of these transmitting devices, such as varying transmitting unit sizes, different emitted sound wave frequencies, and irregular (irregular) arrangements, previously proposed algorithms must be applied to regularly arranged transmitting arrays or are only suitable for ultrasonic waves at a frequency of 40kHz.

[0056] This embodiment does not impose explicit restrictions on the setting of the transmission parameters of the transmitting device; appropriate settings can be made according to the current transmitting device. For example, the operating frequency, spatial location, shape, pointing angle, and modal distribution of the radiating surface of each transmitting device can be set via code to calculate the directivity of the radiated sound field or the sound field distribution within a certain three-dimensional spatial location. Alternatively, relevant sound field results calculated using CAE (Computer-Aided Engineering) can be imported. The initial sound field constructed in this embodiment can cover current mainstream sound field construction requirements, including: focusing (single-point and multi-point), beamforming (unidirectional and multi-directional), acoustic vortices, and arbitrary acoustic patterns, thus making the receiving device unaffected by the usage scenario. Simultaneously, the location of the sound field can be arbitrarily specified (three-dimensional space), and the quality of the constructed sound field still cannot exceed physical limits; it only achieves optimal sound field construction based on current hardware conditions. This acoustic holographic algorithm is based on a defined physical process, using convolution or frequency domain calculations during sound propagation calculations. It is fast and can be calculated in real-time for constructing real-time, high-precision three-dimensional sound field distributions.

[0057] Furthermore, the computing module includes an initialization unit, used to set the transmission parameters of the acoustic holographic phased array, including the operating frequency, impulse response, quantization accuracy of amplitude and phase control, geometric dimensions, placement position, and placement angle of each ultrasonic transmission unit in the phased array probe, to complete the operation initialization;

[0058] The position tracking unit is used to acquire the position of the distributed medical implantable devices. The spatial position of each implantable device is input into the system. If the position of the implantable device is unknown or not fixed, the position of each device is acquired by using an ultrasound imaging method. The ultrasound signal generator excites the ultrasound phased array probe and receives the scattered signals inside the human body. The imaging algorithm obtains the three-dimensional imaging result inside the human body and determines the spatial position of the implantable device relative to the ultrasound phased array probe, thereby realizing real-time tracking of the position of the implantable device.

[0059] An ultrasonic signal conversion unit is used to calculate and set the ultrasonic wireless signal form corresponding to the implanted device at different locations based on the sound field type, sound field intensity and sound field modulation method in the corresponding acoustic holography algorithm.

[0060] The result output unit is used to obtain the optimal phased array probe transmission parameter settings by iteratively optimizing the transmission parameters of the phased array through the algorithm. Then, the ultrasonic signal generator generates a corresponding driving electrical signal for each transmission unit according to the optimal transmission parameters. The ultrasonic phased array probe is electrically driven and transmits different control signals to the corresponding implanted device in a directional, fixed-point, end-to-end manner.

[0061] The emission parameters of the acoustic holographic phased array are set, such as the operating frequency (e.g., 1MHz), impulse response (e.g., impulse response waveform, or 3dB bandwidth), and quantization accuracy of amplitude and phase control (e.g., 2-bit). The geometric dimensions (e.g., square, 1mm side length), placement position (e.g., 16x16 square array with 1mm spacing), and placement angle (e.g., 90 degrees) of each ultrasonic emission unit in the phased array probe are used for the acoustic holography algorithm and imaging algorithm to complete the initialization.

[0062] The location of the distributed medical implants needs to be obtained next. The spatial location of each device can be manually input into the transmission system, for example: (depth 20mm, x offset 5mm, y offset 10mm). For cases where the location is unknown or not fixed, ultrasound imaging can be used to obtain the location of each device. An ultrasound signal generator excites an ultrasound phased array probe and receives the scattered signals inside the human body. The imaging algorithm obtains a 3D image of the human body, thereby determining the spatial location of the device relative to the phased array probe. Ultrasound imaging can be performed in real time, so the device location can be tracked in real time.

[0063] The above process can also be achieved using external devices, with other ultrasound imaging equipment determining the location. After obtaining the locations of several devices distributed in space, the required ultrasonic wireless signal format needs to be set for devices at different locations. The ultrasonic wireless signal format depends on the function to be achieved and the different controlled implanted devices. Continuous ultrasound with a certain sound intensity is used for power supply or charging (e.g., using a sound intensity of 100mW / cm²). 2 The device is powered by ultrasonic waves; during control, ultrasonic pulses are used to trigger hardware (e.g., using pulsed ultrasonic waves to power on / off the device); during communication, modulated ultrasonic pulse sequences are used (e.g., using amplitude, phase, and frequency modulation for acoustic communication).

[0064] The above functional settings can meet most power supply, control, and communication requirements. After setting the required ultrasonic wireless signal format for devices at different locations—corresponding to the sound field type, sound field intensity, and sound field modulation method in the acoustic holography algorithm—the algorithm can begin calculations under these constraints. The algorithm iteratively optimizes the phased array's transmission parameters to construct a high-precision ultrasonic field (high precision in spatial position and sound signal intensity) while minimizing coupling between multiple sound fields constructed by a single transmitting device. This process can also be performed externally using high-performance computing equipment. After obtaining the optimized phased array probe transmission parameter settings, the ultrasonic signal generator generates a corresponding driving electrical signal for each transmitting unit based on the parameters. The ultrasonic phased array probe is electrically driven, transmitting ultrasonic energy, modulation signals, etc., directionally and end-to-end to the corresponding device. The controlled medical implant device receives the corresponding ultrasonic signal, which is then demodulated by the ultrasonic signal demodulation module to remove the control or communication information carried by the ultrasound. For the charging demodulation module, AC signals can be demodulated into DC signals. Subsequently, through the energy management and voltage regulation modules, ultrasonic energy can be extracted and the voltage stabilized to provide a stable power supply to the back-end load. At the same time, control and communication signals are converted into standard logic levels, thus realizing the previously desired functions, including power supply, control, communication, and derivative functions.

[0065] Furthermore, the implantable device to be controlled includes a first implantable device and a second implantable device; the first implantable device is unidirectionally connected to the external acoustic holographic phased array, and the second implantable device is bidirectionally connected to the external acoustic holographic phased array.

[0066] Both the first implantable device and the second device include:

[0067] An ultrasonic transducer is used to receive acoustic energy and convert it into an AC signal;

[0068] An ultrasonic signal demodulation module is used to demodulate the control or communication information carried by ultrasound, and to demodulate the AC signal into a DC signal;

[0069] The energy management and voltage regulation module is used to extract ultrasonic energy and stabilize the voltage, providing a stable power supply to the back-end load. At the same time, it converts control signals and communication signals into standard logic levels, realizing power supply, control, communication, and other derivative functions of the implanted device.

[0070] Furthermore, the second implantable device also includes an ultrasonic signal modulation module, which controls the communication relationship between the implantable device and the external device, modulates the control signal into ultrasonic waves, and transmits them through the ultrasonic transducer. The ultrasonic signals are received by the ultrasonic phased array probe, converted into digital signals by the ultrasonic signal receiver, and demodulated by the computing module or the external device.

[0071] The two-way communication implantable device also includes an ultrasound signal modulation module, enabling communication between the implantable device and external devices, such as transmitting operating status and sensor information. This implantable device modulates information into ultrasound waves via the ultrasound signal modulation module, which are then emitted by the ultrasound transducer. The ultrasound phased array probe receives this ultrasound signal, which is then converted into a digital signal by the ultrasound signal receiver and demodulated by the processing module or external device. Considering the low power consumption of the implantable device, the emitted ultrasound signal is small. This can be coordinated with the phased array transmission control signal; that is, each time the external acoustic holographic phased array transmits a control pulse, the implantable device responds with a communication message, performing time window gating and combining it with spatial position gain to achieve a higher signal-to-noise ratio demodulation.

[0072] Example 2

[0073] like Figure 2 As shown, the present invention provides a control method for medical implantable devices, comprising:

[0074] An external acoustic holographic phased array and at least one implantable device to be controlled, which is wirelessly connected to the external acoustic holographic phased array;

[0075] Step S1: An external acoustic holographic phased array constructs a special sound field and emits ultrasonic waves to the implanted device. This adjusts the implanted devices of different types located at different positions, locates and tracks the position of the implanted devices in motion, performs spatial division multiplexing, and realizes synchronous control of wireless power supply, wireless operation, and wireless communication for the implanted devices at different positions.

[0076] Step S2: The implanted device receives an ultrasonic control signal, sets a corresponding form of ultrasonic wireless signal, powers itself, controls the triggering of itself, and executes its derivative functions.

[0077] The form of the ultrasonic wireless signal depends on the different implanted devices and the different functions implemented by the implanted devices.

[0078] The implantable device to be controlled includes a first implantable device and a second implantable device; the first implantable device is unidirectionally connected to the external acoustic holographic phased array, and the second implantable device is bidirectionally connected to the external acoustic holographic phased array.

[0079] Furthermore, the present invention provides a control method for medical implantable devices, which further includes:

[0080] Obtain the first positioning point of the signal emitted on the external acoustic holographic phased array;

[0081] Determine the second positioning point for receiving signals on different implanted devices;

[0082] Different types of sound waves are emitted from the first positioning point to the second positioning point at different locations in space to complete the reception of the correct signal at the preset position, thereby realizing the secure wireless power supply and data transmission within and outside the electromagnetic shielding range.

[0083] The ultrasonic control signal used in this embodiment is a non-electromagnetic signal. Common wireless eavesdropping and jamming techniques are based on electromagnetic waves, while ultrasonic signals offer greater concealment. Ultrasonic signals are unaffected by electromagnetic shielding systems, such as Faraday cages or other metal shielding nets. Objects enclosed by such cages will not receive external electromagnetic waves, and the outside world cannot receive electromagnetic waves from within. For example, a mobile phone encased in a metal net will lose its signal. Faraday cages are commonly used in electronic laboratories and medical equipment requiring electromagnetic interference resistance; therefore, power supply and communication with such equipment are typically wired. However, this embodiment utilizes acoustic means to achieve wireless power supply and data transmission within the electromagnetic shielding chamber.

[0084] This embodiment employs acoustic holography technology, enabling point-to-point transmission of different types of sound waves to different devices at different locations in space, without interference. Each device receives only its own signal, achieving spatial multiplexing. Traditional communication lacks spatial differentiation, transmitting throughout the entire space; everyone can receive signals from others, but typically, without the key to decode others' signals, decoding is impossible. Acoustic holography, however, ensures that each person's signal is precisely transmitted to the location of each receiving device. Except for the focal point, other locations will not receive the correct signal; only predefined locations will receive the correct signal.

The memory and storage media can be short-term or long-term storage.
