[0057] The core of this application is to provide a multifunctional transcranial therapeutic device and a control method thereof.

[0058] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0059] The multifunctional transcranial therapeutic device of this application is suitable for the treatment of various brain diseases, such as depression, anxiety, Parkinson's disease, Alzheimer's disease, etc. Its multimodal stimulation mode and precise control function enable it to meet the treatment needs of different patients and has broad application prospects.

[0060] The present application provides a multifunctional transcranial therapeutic apparatus, such as Figure 1 As shown, it includes: a central control board, a main controller 11, multiple stimulation heads 12, a transcranial electrical stimulation module, a transcranial magnetic stimulation module, an ultrasonic stimulation module, and a host 13;

[0063] The host 13 is connected to the main controller 11 and is used to send treatment control information to the main controller 11;

[0064] The main controller 11 is connected to the electrical stimulation signal generator, magnetic stimulation signal generator, and ultrasonic signal generator, and is used to control the corresponding signal generator to output control signals to the corresponding electrical stimulation electrodes, magnetic stimulation coils, and ultrasonic transducers in each stimulation head 12 according to the treatment control information.

[0065] This proposal proposes a multifunctional transcranial therapeutic device, the core structure of which includes a central control board, a main controller 11, multiple stimulation heads 12, transcranial electrical stimulation modules, transcranial magnetic stimulation modules, ultrasonic stimulation modules, and a main unit 13. By integrating multiple stimulation methods (electrical, magnetic, and ultrasonic) into a single device and enabling coordinated control of each stimulation module through the central control board and main controller 11, this design aims to address the problems of existing transcranial therapeutic devices, such as their limited functionality, insufficient stimulation accuracy, and difficulty adapting to diverse applications.

[0066] In this embodiment, multiple stimulation heads 12 are respectively integrated with electrical stimulation electrodes, magnetic stimulation coils, and ultrasonic transducers. This design integrates multiple stimulation methods into one stimulation head 12, allowing the device to apply multiple stimulations simultaneously or separately to the same treatment site, thereby enhancing the flexibility and effectiveness of the treatment. For example, when treating certain complex brain diseases, it may be necessary to use electrical stimulation and magnetic stimulation simultaneously to achieve better therapeutic effects, and this integrated design can meet this need. In addition, the design of multiple stimulation heads 12 also enables the device to stimulate multiple treatment sites at the same time, thereby improving treatment efficiency.

[0067] The transcranial electrical stimulation module generates electrical stimulation signals through an electrical stimulation signal generator and transmits these signals to the treatment site via electrical stimulation electrodes. Electrical stimulation is a common transcranial treatment modality, offering advantages such as ease of use and low cost. In this solution, the electrical stimulation module is combined with other stimulation modules to achieve even greater therapeutic potential.

[0068] The transcranial magnetic stimulation module's magnetic stimulation signal generator generates magnetic stimulation signals, which are applied to the treatment area via a magnetic stimulation coil. Magnetic stimulation has the advantages of strong penetration and a wide range of action, making it suitable for treating a variety of brain diseases. In this solution, the magnetic stimulation module is combined with electrical stimulation and ultrasonic stimulation modules to achieve complementary advantages across multiple stimulation modalities, enhancing therapeutic effectiveness.

[0069] The ultrasonic stimulation module's ultrasonic signal generator generates ultrasonic stimulation signals, which are applied to the treatment area via an ultrasonic transducer. Ultrasound stimulation is an emerging transcranial treatment modality with advantages such as high safety and minimal side effects. In this solution, the addition of the ultrasonic stimulation module further enriches the device's stimulation methods, enabling it to better meet the treatment needs of different patients.

[0070] This embodiment integrates multiple signal generators and the main controller 11 on the central control board, reducing the complexity and failure rate of the equipment and improving the stability and reliability of the system. This integrated design not only reduces the cost of the equipment, but also increases the service life of the equipment.

[0071] The host computer 13 is connected to the main controller 11 and is used to send treatment control information to the main controller 11. The host computer 13 provides a user interface, allowing doctors or operators to easily set treatment parameters based on the patient's condition. This design makes the device more user-friendly and improves its usability. Furthermore, the connection between the host computer 13 and the main controller 11 enables remote monitoring and data transmission, facilitating real-time monitoring and analysis of the patient's treatment progress.

[0072] By integrating electrical, magnetic, and ultrasonic stimulation, the device can provide different stimulation methods or combinations for different conditions, significantly improving treatment efficacy and applicability. The integration of multiple stimulation methods and its modular design provide the device with excellent scalability and flexibility, adapting to diverse usage scenarios. This design not only enables the device to meet existing treatment needs but also allows for upgrades and expansion as technology advances and clinical needs change.

[0073] The multifunctional transcranial therapeutic device provided in the present application includes: multiple stimulation heads 12, a transcranial electrical stimulation module, a transcranial magnetic stimulation module, and an ultrasonic stimulation module. The multiple electrical stimulation electrodes of the transcranial electrical stimulation module, the multiple magnetic stimulation coils of the transcranial magnetic stimulation module, and the multiple ultrasonic transducers of the ultrasonic stimulation module are respectively integrated in each stimulation head 12; the central control panel integrates the electrical stimulation signal generator of the transcranial electrical stimulation module, the magnetic stimulation signal generator of the transcranial magnetic stimulation module, the ultrasonic signal generator of the ultrasonic stimulation module and the main controller 11; the transcranial electrical stimulation module can transmit direct current stimulation or alternating current stimulation to regulate the excitability of neurons; the transcranial magnetic stimulation module can provide a pulsed magnetic field to act on specific areas of the brain; the ultrasonic stimulation module generates ultrasonic waves through ultrasonic transducers, which can penetrate the scalp and skull to act on deep brain tissue. Multiple stimulation heads 12 are used to be distributed in different areas of the head. Each stimulation head 12 integrates the electrical stimulation electrodes of the transcranial electrical stimulation module, the magnetic stimulation coil of the transcranial magnetic stimulation module, and the ultrasonic transducer of the ultrasonic stimulation module. The main controller 11 uniformly controls the signal generators of each module to achieve the selection of a single stimulation method or a combination of multiple stimulation methods based on the patient's condition and treatment needs. For example, transcranial magnetic stimulation and transcranial electrical stimulation are used simultaneously. By combining different stimulation methods, the target brain area is synergistically acted on to improve the treatment effect, solving the problem that traditional transcranial therapeutic devices only support a single stimulation method and have poor treatment effects.

[0074] According to the above embodiment, further, the multifunctional transcranial therapeutic apparatus further includes: a slave device and a slave stimulation module;

[0075] The types of the secondary stimulation modules include: one or more of a transcranial electrical stimulation module, a transcranial magnetic stimulation module, and an ultrasonic stimulation module;

[0076] The slave device is in communication with the host device 13 and is configured to receive treatment control information from the host device 13 and control the output of stimulation signals from the stimulation module according to the treatment control information.

[0077] The slave is an auxiliary device of the host 13 and is connected to the host 13 via a communication protocol. It has an independent control unit and data processing capabilities, can receive treatment control information sent by the host 13, and control the output of corresponding stimulation signals from the stimulation module based on this information. The main function of the slave is to expand the functionality of the system and realize multi-scenario application. It can flexibly switch different slave stimulation modules according to the instructions of the host 13 and accurately control the stimulation parameters. In addition, the slave can also feedback the status information of the slave stimulation module in real time, providing data support for the host 13 so that the host 13 can perform further analysis and adjustments.

[0078] The introduction of slaves enables distributed control of the device, improving the flexibility and scalability of the system. By adding slaves, the functionality of the device can be easily expanded without changing the hardware structure of the host 13, meeting the personalized treatment needs of different patients.

[0079] The types of slave stimulation modules include one or more of a transcranial electrical stimulation module, a transcranial magnetic stimulation module, and an ultrasonic stimulation module. These modules can be combined and configured according to actual needs to form a variety of stimulation schemes. The slave stimulation module outputs stimulation signals under the control of the slave device and works in conjunction with the stimulation head 12 controlled by the host 13 to achieve more complex treatment modes. For example, during multi-region treatment, the host 13 can control a stimulation head 12 to stimulate the main region, while the slave device can control the slave stimulation module to stimulate other auxiliary regions, thereby achieving multi-region collaborative treatment.

[0080] According to the above embodiment, further, the multifunctional transcranial therapeutic apparatus further includes: a dynamic tracking module; the dynamic tracking module includes: a head-mounted positioning device, a positioning processing unit, an optical tracking sensor, and an inertial measurement unit sensor;

[0081] The head-mounted positioning device integrates an optical tracking sensor and an inertial measurement unit sensor; the optical tracking sensor and the inertial measurement unit sensor are connected to the positioning processing unit;

[0082] The optical tracking sensor is used to collect the degree of freedom position information of the head-mounted positioning device and send it to the positioning processing unit;

[0083] The inertial measurement unit sensor is used to collect angular velocity and linear acceleration information of the head-mounted positioning device and send it to the positioning processing unit;

[0084] The positioning processing unit is connected to the host 13 and is used to obtain real-time dynamic data of the head-mounted positioning device based on the degree of freedom posture information, angular velocity and linear acceleration information and send it to the host 13.

[0085] Based on the above-mentioned multifunctional transcranial therapeutic device, the design of a dynamic tracking module is further introduced, which can significantly improve the device's precise positioning capability and the stability of the treatment effect.

[0086] The head-mounted positioning device is the core component of the dynamic tracking module. It is fixed to the patient's head and ensures that the optical tracking sensors and inertial measurement unit (IMU) can accurately collect head motion information. The design of the head-mounted positioning device must take into account wearing comfort and stability to ensure that the normal operation of the sensors is not affected by the patient's head movement during treatment.

[0087] The optical tracking sensor is integrated into the head-mounted positioning device to collect the device's degree of freedom position information. By capturing external optical markers or reflection points, the optical tracking sensor obtains the head-mounted positioning device's spatial position and posture information in real time and sends this information to the positioning processing unit.

[0088] The inertial measurement unit (IMU) sensor, integrated into the head-mounted tracking device, collects the device's angular velocity and linear acceleration information. By measuring the head's angular velocity and linear acceleration, the IMU sensor provides dynamic information about head movement and sends this information to the positioning processing unit.

[0089] Optical tracking sensors can provide highly accurate position information, significantly improving positioning accuracy, especially in static or slow-motion scenarios. IMU sensors can provide continuous motion data in high-speed motion scenarios, compensating for signal loss or latency issues that can occur with optical tracking sensors during rapid motion.

[0090] The positioning processing unit is connected to the optical tracking sensor and the inertial measurement unit (IMU) sensor to receive and process the position and motion information collected by the sensors. Based on the degree-of-freedom position information provided by the optical tracking sensor and the angular velocity and linear acceleration information provided by the IMU sensor, a fusion algorithm is used to calculate real-time dynamic data of the head-mounted positioning device and transmit this data to the host 13.

[0091] Data fusion algorithms usually use methods such as Kalman Filter or Extended Kalman Filter (EKF) to combine the high-precision posture information of the optical tracking sensor and the dynamic motion information of the IMU sensor to calculate the real-time dynamic data of the head-mounted positioning device.

[0092] In this embodiment, when multiple brain regions need to be stimulated in a coordinated manner, the dynamic tracking module can monitor head movements in real time to ensure that the stimulation signal of each stimulation head 12 accurately acts on the target brain region.

[0093] According to the above embodiment, further, in the above multifunctional transcranial therapeutic apparatus, the dynamic tracking module further comprises: a pressure sensor array; the pressure sensor array is connected to the positioning processing unit;

[0094] The pressure sensor array is arranged on the side of the head-mounted positioning device that contacts the scalp, and is used to collect pressure information when the head-mounted positioning device contacts the scalp and send it to the positioning processing unit.

[0095] The pressure sensor array of this embodiment is integrated on the side of the head-mounted positioning device that contacts the scalp, and is generally composed of multiple high-sensitivity pressure sensors that are evenly distributed on the inner surface of the head-mounted positioning device.

[0096] The pressure sensor array collects real-time pressure distribution information when the head-mounted positioning device contacts the scalp. This information includes the pressure at the contact point and the uniformity of the pressure distribution. By monitoring this pressure information, it is possible to determine whether the head-mounted positioning device is in close contact with the scalp, thus avoiding poor treatment results or safety hazards caused by poor contact.

[0097] The positioning processing unit receives pressure data collected by the pressure sensor array and performs real-time analysis. By analyzing the uniformity of the pressure distribution and the magnitude of the pressure, the positioning processing unit determines whether the head-mounted positioning device is in close contact with the scalp and feeds this information back to the host computer 13. Based on the pressure information provided by the positioning processing unit, the host computer 13 adjusts the wearing state of the head-mounted positioning device in real time. If poor contact is detected, the host computer 13 can prompt the operator to adjust the position or tightness of the head-mounted positioning device to ensure close contact with the scalp.

[0098] The present application also provides a control method for a multifunctional transcranial therapeutic instrument, which is applied to the multifunctional transcranial therapeutic instrument. The multifunctional transcranial therapeutic instrument includes: a central control board, a main controller 11, multiple stimulation heads 12, a transcranial electrical stimulation module, a transcranial magnetic stimulation module, an ultrasonic stimulation module, and a host 13; multiple electrical stimulation electrodes of the transcranial electrical stimulation module, multiple magnetic stimulation coils of the transcranial magnetic stimulation module, and multiple ultrasonic transducers of the ultrasonic stimulation module are respectively integrated in each stimulation head 12; the central control board integrates an electrical stimulation signal generator of the transcranial electrical stimulation module, a magnetic stimulation signal generator of the transcranial magnetic stimulation module, an ultrasonic signal generator of the ultrasonic stimulation module, and the main controller 11; the host 13 is connected to the main controller 11, and the main controller 11 is connected to the electrical stimulation signal generator, the magnetic stimulation signal generator, and the ultrasonic signal generator;

[0099] like Figure 2 As shown, the method includes:

[0100] receiving treatment mode setting information;

[0101] Determine the operating mode of one or more of the transcranial electrical stimulation module, the transcranial magnetic stimulation module, and the ultrasonic stimulation module according to the treatment mode setting information and generate corresponding treatment control information;

[0102] The treatment control information is sent to the main controller, so that the main controller controls the corresponding signal generator to output control signals to the corresponding electrical stimulation electrodes, magnetic stimulation coils, and ultrasonic transducers in each stimulation head according to the treatment control information.

[0103] The control method of the present application is designed for a multifunctional transcranial therapeutic device. Its core lies in receiving treatment mode setting information, determining the working mode of different stimulation modules, and generating corresponding treatment control information to be sent to the main controller 11, thereby finally achieving precise control of different stimulation elements in each stimulation head 12.

[0104] Receiving treatment mode setting information primarily involves interaction between the host computer 13 and external input devices (such as an operating interface, remote terminal, etc.). The host computer 13 receives treatment mode setting information input by the operator through its user interface. This information may include parameters such as the selected stimulation type (electrical stimulation, magnetic stimulation, ultrasonic stimulation), stimulation intensity, stimulation frequency, and stimulation duration. By receiving this treatment mode setting information, the device can identify the user's needs and adjust the operating mode accordingly.

[0105] After receiving the treatment mode setting information, the control logic or algorithm within the host 13 determines the operating mode of one or more of the transcranial electrical stimulation module, the transcranial magnetic stimulation module, and the ultrasound stimulation module based on this information. For example, if the setting information requires combined transcranial electrical stimulation and ultrasound stimulation, the operating mode of the electrical stimulation module and the ultrasound stimulation module will be determined. Subsequently, the host 13 generates corresponding treatment control information based on the determined operating mode. This information contains specific control instructions, such as stimulation intensity, frequency, duration, and other parameters.

[0106] The host computer 13 transmits the generated treatment control information to the main controller 11 in the central control board via a communication link. Upon receiving this information, the main controller 11, based on its internal control logic, sends corresponding control signals to the electrical stimulation signal generator, magnetic stimulation signal generator, and ultrasonic signal generator. Based on the received control signals, these signal generators generate corresponding stimulation signals and output them to the corresponding electrical stimulation electrodes, magnetic stimulation coils, and ultrasonic transducers in each stimulation head 12, thereby achieving corresponding brain stimulation therapy for the patient.

[0107] The control method of the multifunctional transcranial therapeutic apparatus adopted in the embodiment of the present application is that multiple stimulation heads 12 are used to be distributed in different areas of the head. Each stimulation head 12 is integrated with the electrical stimulation electrode of the transcranial electrical stimulation module, the magnetic stimulation coil of the transcranial magnetic stimulation module, and the ultrasonic transducer of the ultrasonic stimulation module. The main controller 11 uniformly controls the signal generators of each module to achieve the selection of a single stimulation method or a combination of multiple stimulation methods according to the patient's condition and treatment needs, for example, using transcranial magnetic stimulation and transcranial electrical stimulation at the same time. By combining different stimulation methods, the target brain area is synergistically acted on to improve the treatment effect, solving the problem that traditional transcranial therapeutic apparatuses only support a single stimulation method and have poor treatment effect.

[0108] According to the above embodiment, further, in the control method of the multifunctional transcranial therapeutic apparatus, the multifunctional transcranial therapeutic apparatus further includes: a slave device and a slave stimulation module; the type of the slave stimulation module includes: one or more of a transcranial electrical stimulation module, a transcranial magnetic stimulation module, and an ultrasonic stimulation module; the slave device is communicatively connected to the host 13;

[0109] The method also includes:

[0110] Receive access information from the slave device;

[0111] Establish a secure communication channel with the slave;

[0112] The treatment control information is sent to the slave machine, so that the slave machine controls the stimulation module to output the stimulation signal according to the treatment control information.

[0113] This embodiment adds access management for slave devices, secure communication channel establishment, and control of slave stimulation modules. This process enables the device to better adapt to multi-scenario applications and personalized treatment needs, and through the collaborative operation of the master and slave devices, more complex treatment plans can be implemented.

[0114] The slave sends an access request to the master 13 via a communication protocol. The master 13 receives and identifies the slave's access information. This access information may include the slave's device type, functional modules, hardware status, and other details. A secure communication channel is established between the master 13 and the slave using a pre-set communication protocol. The communication protocol can utilize encryption technologies (such as AES-256) and verification mechanisms (such as CRC32) to ensure the security and reliability of data transmission. These encryption and verification mechanisms effectively prevent data leakage and transmission errors, ensuring the safety and reliability of the treatment process. This is particularly important for medical devices that involve patient privacy and treatment safety.

[0115] The host 13 generates treatment control information according to the treatment plan and sends it to the slave through a secure communication channel. After receiving the control information, the slave 13 analyzes and performs corresponding operations to control the stimulation module to output stimulation signals.

[0116] This embodiment introduces a slave device and a slave stimulation module, and adds slave device management and control steps to the control method. The multifunctional transcranial therapeutic device can achieve collaborative work between the master and slave devices, significantly improving the functional scalability and flexibility of the device.

[0117] According to the above embodiment, further, in the control method of the above multifunctional transcranial therapeutic apparatus, the multifunctional transcranial therapeutic apparatus further includes: a dynamic tracking module; the dynamic tracking module includes: a head-mounted positioning device, a positioning processing unit, an optical tracking sensor, and an inertial measurement unit sensor; the optical tracking sensor and the inertial measurement unit sensor are integrated on the head-mounted positioning device; the positioning processing unit is connected to the host 13; the optical tracking sensor and the inertial measurement unit sensor are connected to the positioning processing unit;

[0118] The method also includes:

[0119] Receiving real-time dynamic data of the head-mounted positioning device sent by the positioning processing unit; wherein the real-time dynamic data is obtained by the positioning processing unit based on the degree of freedom posture information collected by the optical tracking sensor and the angular velocity and linear acceleration information collected by the inertial measurement unit sensor;

[0120] receiving pre-input multimodal head structure data;

[0121] Determine the target location information of the target brain area based on multimodal head structure data and real-time dynamic data;

[0122] According to the target position information, the position and angle of the stimulation head 12 are adjusted.

[0123] This embodiment increases the management and utilization of the dynamic tracking module. By receiving real-time dynamic data and multimodal head structure data, the device can accurately locate the target brain area and dynamically adjust the position and angle of the stimulation head 12 to ensure the precise effect of the stimulation signal.

[0124] The positioning processing unit calculates the real-time dynamic data of the head-mounted positioning device (including position, posture, angular velocity, and linear acceleration) by fusing data from the optical tracking sensor and the inertial measurement unit sensor, and sends this data to the host 13 via a communication link. By receiving real-time dynamic data, the host 13 can understand the position and motion status of the head-mounted positioning device in real time, providing a basis for subsequent positioning of the target brain area and adjustment of the stimulation head 12.

[0125] Multimodal head structural data typically includes the patient's magnetic resonance imaging (MRI), computed tomography (CT) images, and brain tissue structure information. This data is pre-entered into the host computer before treatment. 13 By combining multimodal head structural data, the device can more accurately locate the target brain area, improving the specificity and effectiveness of treatment.

[0126] The host 13 uses an algorithm to fuse real-time dynamic data with multimodal head structure data to calculate the real-time position information of the target brain area. This process usually involves complex mathematical models and algorithms, such as finite element analysis and neuronavigation algorithms. Target position information is the key basis for adjusting the position and angle of the stimulation head 12, ensuring that the stimulation signal can accurately act on the target brain area. By dynamically adjusting the target position information, the device can compensate for deviations caused by head movement in real time, ensuring the accuracy and stability of treatment.

[0127] Based on the target position information, the host computer 13 generates corresponding control instructions and sends them to the main controller 11. The main controller 11 adjusts the position and angle of the stimulation head 12 through a drive device (such as a motor or a robotic arm) to ensure that the stimulation signal always accurately acts on the target brain area, thereby improving the treatment effect.

[0128] According to the above embodiment, further, in the control method of the multifunctional transcranial therapeutic apparatus, the multifunctional transcranial therapeutic apparatus further comprises: a pressure sensor array; the pressure sensor array is arranged on the side of the head-mounted positioning device in contact with the scalp;

[0129] The method also includes:

[0130] receiving pressure information collected by the pressure sensor array when the head-mounted positioning device contacts the scalp;

[0131] Determine whether the pressure information is uniform and within the preset pressure range;

[0132] If not, a prompt message is issued to adjust the position of the head-mounted positioning device.

[0133] The embodiment of the present application receives pressure information, determines whether the pressure distribution is uniform and within a preset range, and issues an adjustment prompt when the conditions are not met. The device can ensure that the head-mounted positioning device is in good contact with the scalp, thereby improving the safety and effectiveness of treatment.

[0134] The pressure sensor array is located on the side of the head-mounted positioning device that contacts the scalp, capable of collecting real-time pressure information at the contact point. This pressure information is transmitted to the positioning processing unit or host 13 via wires or wirelessly. This process can be performed on the host 13 or the main controller 11.

[0135] The host 13 or positioning processing unit analyzes the received pressure information to determine whether the pressure distribution is uniform and within a preset pressure range. This preset pressure range can be adjusted based on the patient's comfort and treatment needs. This is a key step in ensuring good contact between the head-mounted positioning device and the scalp. By determining whether the pressure distribution is uniform and within the preset range, the device can promptly detect any poor contact.

[0136] If the pressure information is uneven or outside the preset range, the host 13 generates a prompt and issues an adjustment prompt via the user interface or an external device (such as a mobile phone or tablet). This prompts the operator or patient to adjust the position of the head-mounted positioning device to ensure proper contact. With real-time feedback and prompts, the operator or patient can adjust the device's fit promptly, improving treatment comfort and safety.

[0137] According to the above embodiment, further, the control method of the multifunctional transcranial therapeutic apparatus further includes:

[0138] receiving temperature information of the electrical stimulation electrode;

[0139] Determine whether the temperature information exceeds a preset temperature threshold;

[0140] If it exceeds, the signal generator that controls the transcranial electrical stimulation module stops outputting.

[0141] In the embodiment of the present application, a temperature sensor is installed near the electrical stimulation electrode to monitor the temperature of the electrical stimulation electrode in real time. The temperature sensor transmits the temperature information to the host 13 or the main controller 11 via a wire or wirelessly.

[0142] This determination can be made by either the host computer 13 or the main controller 11. The host computer 13 or the main controller 11 analyzes the received temperature information and determines whether the temperature exceeds a preset safety threshold. The preset temperature threshold can be adjusted based on the device's safety standards and the patient's comfort level. This effectively avoids skin burns and other safety hazards caused by excessive temperatures, improving the safety and reliability of treatment.

[0143] If the judgment result indicates that the temperature exceeds the preset threshold, the host 13 will generate a stop command and send it to the signal generator of the transcranial electrical stimulation module through the main controller 11, causing it to stop outputting the electrical stimulation signal, thereby avoiding safety issues caused by excessive temperature. Through real-time monitoring and automatic protection mechanisms, the device can quickly take measures to ensure patient safety when the temperature is abnormal. This automatic protection mechanism not only improves the safety of the device, but also reduces the burden on the operator. The preset temperature threshold can be adjusted according to the individual differences and treatment needs of the patient, realizing personalized safety protection.

[0144] According to the above embodiment, further, in the control method of the multifunctional transcranial therapeutic apparatus, determining the operating mode of one or more of the transcranial electrical stimulation module, the transcranial magnetic stimulation module, and the ultrasonic stimulation module according to the treatment mode setting information and generating corresponding treatment control information includes:

[0145] According to the treatment mode setting information, the treatment type, treatment intensity, treatment time, treatment frequency and treatment part are obtained;

[0146] Determining the stimulation modules involved in the work according to the treatment type, where the stimulation modules include one or more of a transcranial electrical stimulation module, a transcranial magnetic stimulation module, and an ultrasonic stimulation module;

[0147] Set the stimulation parameters of the stimulation modules involved in the work according to the treatment intensity, treatment time and treatment frequency;

[0148] Determine the location of the target brain area based on the treatment site and multimodal head structure data;

[0149] Corresponding treatment control information is generated based on the determined stimulation module, stimulation parameters and target brain area location information.

[0150] The host 13 receives treatment mode setting information input by the operator through the user interface, and parses the information to obtain parameters such as treatment type (such as electrical stimulation, magnetic stimulation, ultrasonic stimulation or a combination thereof), treatment intensity (such as current intensity, magnetic field intensity, ultrasonic intensity), treatment time, treatment frequency and treatment site.

[0151] Based on the analyzed treatment type, the stimulation modules that need to be involved are determined. For example, if the treatment type is a combination of transcranial electrical stimulation and ultrasound stimulation, the transcranial electrical stimulation module and the ultrasound stimulation module are selected. This clarifies which stimulation modules are required and allows for flexible selection of stimulation modules based on different treatment needs. It supports a combination of multiple stimulation methods, improving the diversity and adaptability of the device.

[0152] The host 13 sets specific stimulation parameters for the stimulation modules involved in the operation based on the analyzed parameters such as treatment intensity, treatment time, and treatment frequency. For example, the host 13 sets the current intensity and pulse frequency of the transcranial electrical stimulation module, and the magnetic field intensity and pulse width of the transcranial magnetic stimulation module.

[0153] Secondly, by combining the treatment site with multimodal head structure data (such as MRI / CT imaging data), an algorithm determines the specific location of the target brain region, ensuring that the stimulation signal precisely acts on the target brain region, improving the targetedness and effectiveness of the treatment.

[0154] The host 13 generates specific treatment control information based on the determined stimulation modules, stimulation parameters, and target brain area location information, and sends this information to the main controller 11 for controlling the operation of each stimulation module.
