Description

Technical Field

[0001] This application relates to the field of medical device and apparatus technology, and more specifically, to an intelligent high-frequency electrosurgical control system and apparatus. Background Technology

[0002] A high-frequency electrosurgical unit is a modern medical device that uses the thermal effect generated by high-frequency current passing through biological tissue to achieve tissue cutting, coagulation, and hemostasis. Since its clinical application in the early 20th century, the high-frequency electrosurgical unit has become an indispensable tool in surgical procedures and is widely used in general surgery, obstetrics and gynecology, urology, otolaryngology, and endoscopic surgery.

[0003] Currently, a typical high-frequency electrosurgical unit (HFOS) typically consists of a high-frequency generator, surgical electrodes, electrode plates, and a cooling system. The high-frequency generator produces stable high-frequency energy, which is conducted through the surgical electrodes to the cutting end of the scalpel, achieving cutting and coagulation of the tissue. In the actual use of HFOS, the accuracy of active power control is a key factor affecting surgical outcomes. During surgery, the output load of the HFOS undergoes drastic and nonlinear changes, causing continuous changes in the magnitude and impedance angle of the load impedance. However, traditional control systems usually only sample the amplitude of the output voltage and current to calculate apparent power, or approximate it as active power, ignoring the influence of the phase difference between voltage and current, i.e., the impedance angle. When the load is inductive or capacitive, there is a significant deviation between the apparent power and the actual active power acting on the tissue, causing the actual output energy to deviate from the set range, affecting the consistency of cutting or coagulation effects, and even increasing the risk of tissue thermal damage.

[0004] Therefore, how to provide an intelligent high-frequency electrosurgical control system that can perform precise power closed-loop control, thereby stabilizing the active power within a set threshold range when tissue impedance changes, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides an intelligent high-frequency electrosurgical control system that can perform precise power closed-loop control, thereby stabilizing the active power within a set threshold range when tissue impedance changes.

[0006] The technical solution provided in this application is as follows: This application provides an intelligent high-frequency electrosurgical unit control system, comprising: a high-frequency energy generation module for generating high-frequency, high-power signals and adjusting output power; an output module disposed at the output end of the high-frequency energy generation module and connected to system peripherals; an output sampling and detection module connected to system peripherals for acquiring high-frequency output voltage and current signals; a control module connected to the high-frequency energy generation module and the output sampling and detection module for performing impedance angle calculation and active power control according to a preset control cycle; a human-machine interface module connected to the control module; a host computer debugging module connected to the control module for system debugging and data reporting; and a power supply module connected to the high-frequency energy generation module, output module, output sampling and detection module, control module, human-machine interface module, and host computer debugging module for providing power to each functional module.

[0007] Furthermore, in a preferred embodiment of the present invention, the control module includes: Isolated and non-isolated areas that are electrically isolated from each other; An optically isolated communication module that connects the isolated area and the non-isolated area for data communication and for exchanging synchronization signals and control signals between the two; The isolation zone is equipped with a periodic timer for generating interrupt signals and synchronization signals for the control cycle; The non-isolated area is equipped with a TIMER module for outputting two complementary PWM waveforms with programmable interrupt times.

[0008] Further, in a preferred embodiment of the present invention, the control module is configured as follows: the isolation zone synchronously samples the high-frequency output voltage and current signals via the output sampling and detection module, performs windowing processing and frequency domain analysis on the sampled data, calculates the amplitude and phase difference of the voltage and current, and sends the amplitude and phase difference data to the non-isolated zone via the optocoupler isolation communication module; the non-isolated zone calculates the active power on the system peripherals based on the received amplitude and phase difference, uses the active power as a feedback quantity, and outputs a control quantity through a control algorithm to adjust the output voltage of the high-frequency energy generation module; the specific configuration includes: Upon system power-up, peripheral initialization is performed in both the isolated and non-isolated zones. The isolation zone waits for the interrupt signal generated by the periodic timer. When the interrupt occurs, a new control cycle is started. At the same time, the periodic timer generates a synchronization signal and sends it to the non-isolated zone through the optocoupler isolation communication module to synchronize the processor timing. The isolation zone synchronously acquires high-frequency output voltage and current signals through the output sampling and detection module, and moves the sampled data to memory; The isolation zone performs windowing processing on the voltage and current sampling data collected in the previous control cycle, uses frequency domain analysis algorithms to calculate the voltage amplitude, current amplitude and phase difference, and compensates and corrects the calculation results; The isolation zone reads the data channel level status of the optocoupler isolation communication module. If the level read in the previous control cycle is high, the current control cycle is determined to be a valid output state. The calculated voltage amplitude, current amplitude, and phase difference are retained and filtered. If the level read in the previous cycle is low, it is determined to be an invalid output state, and the calculation results are discarded. The isolation zone sends the processed voltage amplitude, current amplitude, and phase difference to the non-isolation zone through the optocoupler isolation communication module. The non-isolation zone calculates the active power on the load based on the received amplitude and phase difference, and uses it as the feedback active power. Then, based on the control algorithm and the deviation between the set power and the feedback active power, it outputs a digital control quantity for power control. The non-isolated zone converts digital control signals into analog voltage signals, adjusts the output voltage of the high-frequency energy generation module, and stabilizes the active power within the set range.

[0009] Furthermore, in a preferred embodiment of the present invention, the isolation zone comprises: Peripheral detection optical coupler isolation module connected to system peripherals; A first ADC module connected to the output sampling and detection module, used to synchronously sample the high-frequency output voltage and current signals and convert them into digital quantities; A first main control MCU connected to the first ADC module, used to perform frequency domain analysis on the digital quantity and calculate the voltage amplitude, current amplitude and phase difference between voltage and current; The first UART module and the first DMA module are configured on the first main control MCU and connected to the optocoupler isolated communication module.

[0010] Furthermore, in a preferred embodiment of the invention, the non-isolated area includes: Second main control MCU; The second main control MCU is used to calculate the active power of the external circuitry based on the voltage amplitude, current amplitude, and phase difference, and set it as the feedback power; The load detection module is connected to the second main control MCU; The second UART module and the second DMA module are configured on the second main control MCU and connected to the optocoupler isolated communication module. The SPI module is located on the second main control MCU and connected to the human-machine interaction module. A MOS drive module connected to the TIMER module for amplifying the power of the PWM waveform signal and enhancing its driving capability; The second ADC module is located on the second main control MCU and connected to the MOS driver module. The GPIO module is set on the second main control MCU; A relay control module connected to the GPIO module is used to control the power supply and output switching of the system. A power control module installed on the second main control MCU, used to output digital control quantities based on the deviation between the system set power and the feedback active power; Connected to the power control module, it is a DAC (Digital-to-Analog Converter) used to convert digital control quantities into analog voltage signals.

[0011] Furthermore, in a preferred embodiment of the present invention, the high-frequency energy generating module includes: Connected to the DAC digital-to-analog converter, it is used as a step-down regulator to output an adjustable DC voltage based on an analog voltage signal; The push-pull inverter module is connected to the buck regulator and the MOS drive module. The push-pull inverter module includes: a center-tapped transformer, a first MOSFET switch and a second MOSFET switch connected to the center-tapped transformer; The center-tapped transformer is connected to the output terminal of the step-down regulator. The gates of the first MOSFET switch and the second MOSFET switch are respectively connected to the corresponding output terminals of the MOS drive module, which are used to alternately conduct under the control of the two complementary PWM waveforms output by the TIMER module to invert DC power into AC square wave signals. Connected to the output of the push-pull inverter module, this is an LC resonant frequency selection module used to filter AC square wave signals into high-frequency sine wave signals. A DC blocking load module is located at the output end of the LC resonant frequency selective module and connected to the output module.

[0012] Furthermore, in a preferred embodiment of the present invention, the power module includes: Medical power supplies used to rectify, isolate, and step down AC mains power into multiple DC outputs; A low-voltage auxiliary power management module connected to the medical power supply for regulating and filtering multiple DC power sources.

[0013] Furthermore, in a preferred embodiment of the present invention, the human-computer interaction module includes: Human-computer interaction main control MCU; The screen display module is connected to the human-machine interaction main control MCU; Connected to the human-machine interface main control MCU, it is a user operation module used to perform power adjustment; A prompting module connected to the human-machine interaction main control MCU is used to indicate the working status; Connected to the human-machine interaction main control MCU, there are a human-machine debugging module and a human-machine communication module used for system debugging and data interaction, respectively. The data storage module and power management module are connected to the human-machine interaction main control MCU.

[0014] Furthermore, in a preferred embodiment of the present invention, the control module further includes: a crest factor control counter disposed within the non-isolation zone, the crest factor control counter being configured to perform crest factor control and detection in conjunction with the control module, specifically including: The non-isolated zone maintains the peak factor control counter, increments it in each control cycle, and obtains the switching count value corresponding to the current working mode of the system. The counter value is then compared with the switching count value. When the count value of the peak factor control counter is less than the switching count value, the non-isolated zone control TIMER module outputs two complementary PWM waveforms with dead time, driving the high-frequency energy generation module to generate a continuous sine wave output. When the count value of the peak factor control counter is greater than or equal to the switching count value, the non-isolated area triggers the braking event of the TIMER module, forcing both complementary PWM output channels of the TIMER module to be set to low level to turn off the output waveform. Subsequently, the non-isolated area sends a peak factor control status flag to the isolated area through a data channel in the optically isolated communication module. A high level indicates that the current control cycle is in a sinusoidal output state, and a low level indicates that the output is off. After completing the frequency domain analysis in each control cycle, the isolation zone reads the data channel level status of the previous control cycle: if it is high, the voltage amplitude, current amplitude and phase difference calculated in this cycle are retained and filtered; if it is low, the calculation results are discarded. The isolation zone sends the filtered data to the non-isolation zone. The non-isolation zone calculates the active power of the continuous sinusoidal output based on the received voltage amplitude, current amplitude, and phase difference, and then multiplies it by the duty cycle of the intermittent output in the current working mode to obtain the actual active power under the intermittent output state.

[0015] In addition, this application also provides another technical solution: This application discloses an intelligent high-frequency electrosurgical unit control device, which includes the intelligent high-frequency electrosurgical unit control system.

[0016] This invention provides an intelligent high-frequency electrosurgical control system and device, wherein the intelligent high-frequency electrosurgical control system includes: a high-frequency energy generation module for generating high-frequency high-power signals and adjusting output power; an output module disposed at the output end of the high-frequency energy generation module and connected to system peripherals; an output sampling and detection module connected to system peripherals for acquiring high-frequency output voltage and current signals; a control module connected to the high-frequency energy generation module and the output sampling and detection module for performing impedance angle calculation and active power control according to a preset control cycle; a human-machine interaction module connected to the control module; a host computer debugging module connected to the control module for system debugging and data reporting; and a power supply module connected to the high-frequency energy generation module, output module, output sampling and detection module, control module, human-machine interaction module, and host computer debugging module for providing power to each functional module. The main structure of the intelligent high-frequency electrosurgical control system consists of a high-frequency energy generation module, an output module, an output sampling and detection module, a control module, a human-machine interaction module, a host computer debugging module, and a power supply module. The power supply module provides a stable and reliable power supply for the entire system. The high-frequency energy generation module, output module, output sampling and detection module, control module, human-machine interaction module, and host computer debugging module are all electrically connected to the power supply module. The control module, serving as the system's central hub, coordinates the operation of various functional modules and implements system-level control. It consists of electrically isolated and non-isolated zones and employs a dual-processor architecture to handle drive control and signal sampling processing. Simultaneously, through timing control and a pipelined program architecture, the control module distributes the originally sequential sampling, analysis, and control tasks into parallel execution within continuous control cycles, effectively improving the system's real-time sampling performance, control frequency, and data throughput. The high-frequency energy generation module generates high-frequency, high-power signals, and its output power is adjustable under the control module's regulation. Its output is connected to the output module, transmitting the high-frequency energy to system peripherals. The output sampling and detection module is connected to the system peripherals for real-time acquisition of high-frequency signals. The system outputs voltage and current signals and feeds the sampled data back to the control module. The isolation zone in the control module performs windowing and frequency domain analysis on the sampled data, calculates the voltage amplitude, current amplitude, and phase difference, and sends the data to the non-isolated zone via an optocoupler-isolated communication module. The non-isolated zone calculates the active power on the load based on the received data, uses this active power as a feedback quantity, compares it with the set power, and generates a control quantity through a control algorithm to adjust the output voltage of the high-frequency energy generation module, thereby stabilizing the active power within the set range when the tissue impedance changes. Simultaneously, the human-machine interface module allows the operator to set the set power, select the working mode, and view the operating status, while the host computer debugging module is used for data monitoring and performance optimization during system development.Therefore, the technical solution of the present invention, compared with the prior art, can perform precise power closed-loop control, thereby stabilizing the active power within the set threshold range when the tissue impedance changes.

[0025] like Figures 1 to 16 As shown in the figure, an intelligent high-frequency electrosurgical control system provided in this application includes: a high-frequency energy generation module 1 for generating high-frequency high-power signals and adjusting output power; an output module 2 disposed at the output end of the high-frequency energy generation module 1 and connected to system peripherals; an output sampling and detection module 3 connected to system peripherals for acquiring high-frequency output voltage and current signals; a control module 4 connected to the high-frequency energy generation module 1 and the output sampling and detection module 3 for performing impedance angle calculation and active power control according to a preset control cycle; a human-machine interaction module 5 connected to the control module 4; a host computer debugging module 6 connected to the control module 4 for system debugging and data reporting; and a power supply module 7 connected to the high-frequency energy generation module 1, output module 2, output sampling and detection module 3, control module 4, human-machine interaction module 5, and host computer debugging module 6 for providing power to each functional module. The technical solution of this invention, compared with the prior art, can perform precise power closed-loop control, thereby stabilizing the active power within a set threshold range when tissue impedance changes.

[0026] The technical solution of this application will be described in detail below with reference to specific embodiments: Specifically, in a specific embodiment of the present invention, the control module 4 includes: an isolation zone 8 and a non-isolation zone 9 that are electrically isolated from each other; an optocoupler-isolated communication module 10 connecting the isolation zone 8 and the non-isolation zone 9 for data communication and exchanging synchronization signals and control signals between them; a periodic timer 801 for generating interrupt signals and synchronization signals for the control cycle is provided in the isolation zone 8; and a TIMER module 901 for outputting two complementary PWM waveforms with programmable interrupt times is provided in the non-isolation zone 9.

[0027] like Figure 3 , 4 As shown, in this embodiment of the invention, the control module 4 consists of the isolation zone 8, the non-isolation zone 9, and the optocoupler-isolated communication module 10 connecting the two, forming a dual-processor and isolated communication architecture for the control module 4. The isolation zone 8 serves as the core for patient-side signal sampling and processing, and incorporates a built-in periodic timer 801. This timer generates interrupt and synchronization signals at fixed time intervals: the interrupt signal triggers the first main control MCU 804 in the isolation zone 8 to execute a new round of control cycle tasks (such as starting ADC sampling and data processing), while the synchronization signal is transmitted to the non-isolation zone 9 via the optocoupler-isolated communication module 10, providing the same time reference for the second main control MCU 902 in the non-isolation zone 9, thus achieving precise timing synchronization between the two processors. The non-isolation zone 9 contains a TIMER module 901, which outputs two complementary PWM waveforms with dead time, which are amplified by the MOS driver module 907 and then drive the push-pull inverter module 102. Simultaneously, the TIMER module 901 supports programmable intermittent output to meet the differentiated peak factor requirements of different surgical modes. The optocoupler-isolated communication module 10 not only transmits sampling data and control commands bidirectionally, but also specifically exchanges synchronization signals and peak factor status flags to ensure accurate identification of valid sampling data in the isolation zone 8 under intermittent output mode. Through this architecture, the control module 4 ensures electrical isolation safety between the patient circuit and the control circuit, while also achieving high-precision active power closed-loop control and flexible multi-mode waveform output, significantly improving the reliability and surgical adaptability of the high-frequency electrosurgical system.

[0028] Specifically, in a specific embodiment of the present invention, the control module 4 is configured as follows: the isolation zone 8 synchronously samples the high-frequency output voltage and current signals via the output sampling and detection module 3, performs windowing processing and frequency domain analysis on the sampled data, calculates the amplitude and phase difference of the voltage and current, and sends the amplitude and phase difference data to the non-isolated zone 9 through the optocoupler isolation communication module 10; the non-isolated zone 9 calculates the active power on the system peripherals based on the received amplitude and phase difference, uses the active power as a feedback quantity, and outputs a control quantity through a control algorithm to adjust the output voltage of the high-frequency energy generation module 1; The specific configuration includes: upon system power-on, isolation zone 8 and non-isolation zone 9 respectively perform peripheral initialization; isolation zone 8 waits for the interrupt signal generated by the periodic timer 801, and when the interrupt occurs, a new control cycle is started; simultaneously, the periodic timer 801 generates a synchronization signal and sends it to non-isolation zone 9 through the optocoupler isolation communication module 10 to synchronize the processor timing; isolation zone 8 synchronously collects high-frequency output voltage and current signals through the output sampling detection module 3 and moves the sampled data to memory; isolation zone 8 performs windowing processing on the voltage and current sampling data collected in the previous control cycle, uses a frequency domain analysis algorithm to calculate the voltage amplitude, current amplitude, and phase difference, and compensates and corrects the calculation results; isolation zone 8 reads the data channel level status of the optocoupler isolation communication module 10, and if the previous control... If the level read in the control cycle is high, the current control cycle is determined to be an effective output state. The calculated voltage amplitude, current amplitude, and phase difference are retained and filtered. If the level read in the previous cycle is low, it is determined to be an invalid output state, and the calculation results are discarded. Isolation zone 8 sends the processed voltage amplitude, current amplitude, and phase difference to non-isolation zone 9 through optocoupler isolation communication module 10. Non-isolation zone 9 calculates the active power on the load based on the received amplitude and phase difference, as the feedback active power. Then, based on the control algorithm and the deviation between the set power and the feedback active power, a digital control quantity for power control is output. Non-isolation zone 9 converts the digital control quantity into an analog voltage signal, adjusts the output voltage of high-frequency energy generation module 1, and stabilizes the active power within the set range.

[0029] Among them, such as Figure 2 , 14As shown in Figure 15, in this embodiment of the invention, the control module 4 serves as the control center of the system, performing impedance angle calculation and active power closed-loop control. After the system is powered on, the isolation zone 8 and the non-isolation zone 9 are initialized respectively. The periodic timer 801 in the isolation zone 8 generates an interrupt signal and a synchronization signal according to a preset control cycle: the interrupt signal triggers the isolation zone 8 to start a new round of control tasks, and the synchronization signal is sent to the non-isolation zone 9 through the optocoupler isolation communication module 10 to achieve timing synchronization of the two processors. In each control cycle, the isolation zone 8 synchronously collects the high-frequency output voltage and current signals through the output sampling detection module 3, and moves the sampled data to memory through DMA. Subsequently, the isolation zone 8 performs windowing processing and frequency domain analysis on the data collected in the previous cycle. In this embodiment, the Goertzel algorithm is used to calculate the voltage amplitude, current amplitude, and phase difference, and the calculation results are compensated and corrected. This process is the digital processing of the high-frequency sampled signal. Next, isolation zone 8 reads the data channel level status of optocoupler isolation communication module 10: if the level of the previous cycle was high (effective output state), the calculation result is retained and filtered; if it was low (intermittent off state), the data is discarded. Isolation zone 8 sends the processed voltage amplitude, current amplitude, and phase difference to non-isolation zone 9. Non-isolation zone 9 calculates the active power on the load based on these data, uses it as feedback, compares it with the set power, and generates a digital control quantity through a control algorithm—PID or LADRC. This control quantity is converted into an analog voltage by a DAC, adjusting the output voltage of high-frequency energy generation module 1 to stabilize the active power within the set range. It can be seen that the control module 4 is configured to form a three-cycle pipeline architecture of "sampling → analysis → control," significantly improving the real-time response speed and control frequency of the system, ensuring accurate and stable power output under varying impedance and different operating modes.

[0030] Specifically, in a specific embodiment of the present invention, the isolation zone 8 includes: a peripheral detection optocoupler isolation module 802 connected to the system peripherals; a first ADC module 803 connected to the output sampling detection module 3 for synchronously sampling high-frequency output voltage and current signals and converting them into digital quantities; a first master control MCU 804 connected to the first ADC module 803 for performing frequency domain analysis on the digital quantities and calculating voltage amplitude, current amplitude, and phase difference between voltage and current; and a first UART module 805 and a first DMA module 806 disposed on the first master control MCU 804 and connected to the optocoupler isolation communication module 10.

[0031] like Figure 5As shown, in this embodiment of the invention, the isolation zone 8 serves as the core unit for patient-side signal sampling and processing, undertaking the task of synchronous acquisition and digital processing of high-frequency output voltage and current signals. Under the control of the first main control MCU 804, the first ADC module 803 synchronously samples the voltage and current signals with the system output and converts them into digital quantities. The first main control MCU 804 performs windowing processing and Goertzel frequency domain analysis on the acquired digital quantities, calculates the voltage amplitude, current amplitude, and phase difference between voltage and current, and compensates and corrects the calculation results. The peripheral detection optocoupler isolation module 802 is used to monitor the connection status of system peripherals (such as neutral plate, control handle, foot switch) in real time, and securely transmits the status signals to the first main control MCU 804 through the optocoupler isolation communication module 10. The processed amplitude, phase difference, and peripheral status data are sent to the non-isolated zone 9 via the first UART module 805 and the first DMA module 806, through the optocoupler isolation communication module 10, providing accurate feedback for power closed-loop control. This architecture ensures electrical isolation between the patient circuit and the control circuit, while also enabling accurate measurement of high-frequency signals.

[0032] Specifically, in a specific embodiment of the present invention, the non-isolated area 9 includes: a second master control MCU 902; the second master control MCU 902 is used to calculate the active power of the external system based on the voltage amplitude, current amplitude, and phase difference, and set it as the feedback power; a load detection module 903 connected to the second master control MCU 902; a second UART module 904 and a second DMA module 905 disposed on the second master control MCU 902 and connected to the optocoupler isolated communication module 10; an SPI module 906 disposed on the second master control MCU 902 and connected to the human-machine interaction module 5; and a TIMER module 901 connected to process the PWM waveform signal. The system comprises: a MOS driver module 907 that amplifies the power and enhances its driving capability; a second ADC module 908 connected to the MOS driver module 907 and mounted on the second main control MCU 902; a GPIO module 909 mounted on the second main control MCU 902; a relay control module 910 connected to the GPIO module 909 for controlling the power supply and output switching; a power control module 911 mounted on the second main control MCU 902 for outputting digital control quantities based on the deviation between the system set power and the feedback active power; and a DAC digital-to-analog converter 912 connected to the power control module 911 for converting the digital control quantities into analog voltage signals.

[0033] Specifically, in a specific embodiment of the present invention, the non-isolated area 9 further includes: a JTAG debugging module 913 and an LED indicator module 914 connected to the second main control MCU 902.

[0034] Among them, such as Figure 6 As shown, in this embodiment of the invention, the non-isolated zone 9 serves as the core of the system's control decision-making and power drive, responsible for power closed-loop control, peak factor adjustment, and human-machine interaction management. The second main control MCU 902 receives voltage amplitude, current amplitude, and phase difference data from the isolation zone 8 through the second UART module 904 and the second DMA module 905, and calculates the actual active power on the load as feedback. The power control module 911 compares the feedback with the set power obtained from the human-machine interaction module 5 through the SPI module 906, generates a digital control quantity through a PID or LADRC control algorithm, and converts it into an analog voltage signal through a DAC digital-to-analog converter 912 to adjust the output voltage of the high-frequency energy generation module 1. Under the control of the second main control MCU 902, the TIMER module 901 outputs two complementary PWM waveforms with dead time. The interval between these waveforms can be programmed and set by the peak factor control counter 915 according to the surgical mode (pure cutting, mixed cutting, coagulation) to generate output waveforms with different peak factors. This PWM waveform is amplified by the MOS drive module 907 and then drives the push-pull inverter module 102. The GPIO module 909 is connected to the relay control module 910 and is used to control the on / off state of the system power supply and high-frequency output; the second ADC module 908 is used to monitor the MOS drive current and realize overcurrent protection; the load detection module 903 is used to assist in judging the output load status. Through the above architecture, the non-isolated area 9 achieves high-precision active power control and multi-mode waveform output while ensuring electrical isolation safety.

[0035] Specifically, in a specific embodiment of the present invention, the high-frequency energy generation module 1 includes: a buck regulator 101 connected to the DAC digital-to-analog converter 912, used for outputting an adjustable DC voltage based on an analog voltage signal; a push-pull inverter module 102 connected to the buck regulator 101 and the MOS drive module 907; the push-pull inverter module 102 includes: a center-tapped transformer 11, a first MOSFET switch 12 and a second MOSFET switch 13 connected to the center-tapped transformer 11; the center-tapped transformer 11 is connected to the buck regulator 101. The output terminals of the first MOSFET switch 12 and the second MOSFET switch 13 are respectively connected to the corresponding output terminals of the MOS drive module 907, and are used to alternately conduct under the control of the two complementary PWM waveforms output by the TIMER module 901 to invert DC power into AC square wave signals; the output terminal of the push-pull inverter module 102 is connected to the LC resonant frequency selection module 103, which is used to filter the AC square wave signal into a high-frequency sine wave signal; the output terminal of the LC resonant frequency selection module 103 is provided and connected to the output module 2 to the DC blocking load module 104.

[0036] like Figure 2 , 9 As shown, in this embodiment of the invention, the high-frequency energy generation module 1 serves as a power output stage, converting the DC energy provided by the non-isolated zone 9 into a high-frequency, high-power sine wave signal. The analog voltage signal output by the DAC digital-to-analog converter 912 controls the buck regulator 101, causing it to output an adjustable DC voltage. This voltage powers the push-pull inverter module 102 via the center-tapped transformer 11. The two complementary PWM waveforms output by the TIMER module 901 are amplified by the MOS driver module 907, driving the first MOSFET switch 12 and the second MOSFET switch 13 to conduct alternately, causing the primary current direction of the center-tapped transformer 11 to change periodically, thereby outputting an AC square wave signal on the secondary side. This square wave signal enters the LC resonant frequency selection module 103, and after filtering, forms a high-frequency sine wave with a frequency of 350kHz. The DC blocking load module 104 is connected in series in the output circuit to isolate the DC component, preventing the patient from receiving DC shock, while simultaneously transmitting high-frequency energy to the output module 2, ultimately acting on the surgical electrodes. The high-frequency energy generation module 1 integrates DC-AC inverter, frequency selection, power amplification, and safety isolation, providing stable and clean high-frequency energy output for the electrosurgical unit.

[0037] Specifically, in a specific embodiment of the present invention, the power module 7 includes: a medical power supply 701 for rectifying, isolating and stepping down AC mains power into multiple DC power outputs; and a low-voltage auxiliary power management module 702 connected to the medical power supply 701 for stabilizing and filtering the multiple DC power outputs.

[0038] Among them, such as Figure 10 , 12 As shown in this embodiment of the invention, the power supply module 7 provides stable and reliable operating power to the entire system. The medical power supply 701 rectifies, isolates, and steps down the 220V / 50Hz AC mains power to output multiple DC power sources, including +48V, ±12V, and +5V. The +48V serves as the main power supply for the high-frequency energy generation module 1, used to generate high-frequency, high-power signals. The ±12V and +5V are then supplied to the low-voltage auxiliary power management module 702, where further voltage regulation and filtering generate secondary power supplies such as 3.3V, isolated 5V, and a flyback isolated power supply. These provide clean and stable operating voltages for the control module 4, the human-machine interface module 5, the peripheral detection optocoupler isolation module 802, and the optocoupler isolation communication module 10, respectively. This hierarchical power supply architecture satisfies the electrical isolation requirements between the high-voltage power circuit and the low-voltage control circuit, while also ensuring the system's anti-interference capability and operational reliability in complex electromagnetic environments.

[0039] Specifically, in a specific embodiment of the present invention, the human-machine interaction module 5 includes: a human-machine interaction main control MCU 501; a screen display module 502 connected to the human-machine interaction main control MCU 501; a user operation module 503 connected to the human-machine interaction main control MCU 501 for performing power adjustment; a prompt module 504 connected to the human-machine interaction main control MCU 501 for indicating working status; a human-machine debugging module 505 and a human-machine communication module 506 connected to the human-machine interaction main control MCU 501 for system debugging and data interaction, respectively; a data storage module and a power management module connected to the human-machine interaction main control MCU 501.

[0040] like Figure 11 As shown in this embodiment of the invention, the human-machine interaction module 5 serves as the interface between the operator and the system, responsible for receiving user commands and displaying system status. The human-machine interaction main control MCU 501 exchanges data with the control module 4 through the SPI module 906 to obtain system operating parameters and report user-defined values. The screen display module 502 uses an LCD capacitive touchscreen to display information such as system menus, operating modes, set power, and real-time output power. The user operation module 503 includes knobs and buttons, which work in conjunction with the touchscreen to complete operations such as power setting, mode selection, and output start / stop. The prompt module 504 includes a working indicator light and a speaker to indicate the system's operating status and emit operation prompts. The human-machine debugging module 505 connects to a host PC via a USB-to-serial port circuit to realize debugging functions such as waveform monitoring, parameter calibration, and fault diagnosis. The human-machine communication module 506 interacts with the control module 4 through the SPI interface. The data storage module stores interface resources, system operating logs, and user configuration parameters. The power management module provides a stable power supply for all the above components. Through the above integrated design, the human-computer interaction module 5 provides an intuitive and convenient operating experience, while also supporting system development and maintenance.

[0041] Specifically, in a specific embodiment of the present invention, the control module 4 further includes: a peak factor control counter 915 disposed within the non-isolation zone 9, the peak factor control counter 915 being configured to perform peak factor control and detection in conjunction with the control module 4, the specific configuration including: Non-isolated region 9 maintains the crest factor control counter 915, increments it in each control cycle, and obtains the switching count value corresponding to the current operating mode of the system. The counter value is compared with the switching count value. When the crest factor control counter 915 is less than the switching count value, non-isolated region 9 controls the TIMER module 901 to output two complementary PWM waveforms with dead time, driving the high-frequency energy generation module 1 to generate a continuous sine wave output. When the crest factor control counter 915 is greater than or equal to the switching count value, non-isolated region 9 triggers a braking event on the TIMER module 901, forcing both complementary PWM output channels of the TIMER module 901 to a low level to shut down the output waveform. Subsequently, the non-isolated region 9... Isolation zone 9 sends a peak factor control status flag to isolation zone 8 through a data channel in the optocoupler isolation communication module 10. A high level indicates that the current control cycle is in a sinusoidal output state, and a low level indicates that the output is off. After completing the frequency domain analysis in each control cycle, isolation zone 8 reads the data channel level status of the previous control cycle: if it is high, it retains the voltage amplitude, current amplitude, and phase difference calculated in this cycle and performs filtering; if it is low, it discards the calculation results. Isolation zone 8 sends the filtered data to non-isolation zone 9. Non-isolation zone 9 calculates the active power when the sinusoidal wave is continuously output based on the received voltage amplitude, current amplitude, and phase difference, and then multiplies it by the duty cycle of the intermittent output in the current working mode to obtain the actual active power in the intermittent output state.

[0042] Among them, such as Figure 14As shown, in this embodiment of the invention, the peak factor control counter 915 serves as the core mechanism for realizing multi-mode output (pure cut, mixed cut, coagulation), working in conjunction with the TIMER module 901 and the data processing flow of the isolation zone 8 to complete the programmable control of the peak factor and accurate detection of active power under intermittent output. Specifically, a peak factor control counter 915 is maintained inside the non-isolation zone 9, and this counter automatically increments in each control cycle. The system presets a corresponding switching count value according to the current surgical mode (such as pure cut, mixed cut, coagulation): in pure cut mode, the switching count value is equal to the total number of control cycles, that is, a waveform is output in each cycle; in mixed cut mode, one cycle is output every two cycles; in coagulation mode, one cycle is output every three cycles. Non-isolated zone 9 compares the current value of the counter with the switching count value: when the count value is less than the switching count value, non-isolated zone 9 controls the TIMER module 901 to output two complementary PWM waveforms with dead time, driving the high-frequency energy generation module 1 to generate a continuous sine wave; when the count value reaches or exceeds the switching count value, non-isolated zone 9 triggers the braking event of the TIMER module 901, forcing the two PWM output channels to go low, thereby turning off the output waveform and achieving waveform discontinuity. At the same time, non-isolated zone 9 sends the crest factor control status flag to isolated zone 8 in real time through the dedicated data channel in the optocoupler isolation communication module 10: a high level indicates that the current control cycle is in a sine wave effective output state, and a low level indicates that the output is off.

[0043] like Figure 15 As shown in this embodiment of the invention, to achieve precise planning of the system task execution timing, the dual processors in the isolation zone 8 and the non-isolation zone 9 adopt a synchronous execution mechanism to control the timing of data processing and calculation. Specifically, the first master control MCU 804 uses its internal periodic timer 801 module to generate a synchronization signal with a timing period, which is transmitted in PWM form on the low-speed isolation channel. The second master control MCU 902 in the non-isolation zone 9 captures the rising edge of this synchronization signal through its internal TIMER module 901, using this as the trigger source for periodic program events. This enables the two master control units to start task execution under the same time base, thus facilitating the confirmation of the task execution structure and the planning of data processing. For the MCU in the isolation zone 8, after completing the windowing processing of the ADC sampled data, software triggers the synchronous sampling of the two ADCs. By configuring DMA to continuously transfer the ADC sampled data, the sampled data can be transferred to a specified memory location during the CPU's frequency domain analysis, further reducing the time consumed in a single control cycle. After completing the frequency domain analysis, the data is filtered and sent to the MCU in the non-isolation zone 9, where data reception, power calculation, and power control are performed in the next control cycle.

[0044] In addition, this application also provides another technical solution: This application discloses an intelligent high-frequency electrosurgical unit control device, which includes the intelligent high-frequency electrosurgical unit control system.

[0045] This invention relates to an intelligent high-frequency electrosurgical unit control system, which solves the problems of low active power control accuracy, inaccurate power measurement in intermittent output mode, and large response delay in traditional software architecture caused by neglecting voltage and current phase differences in existing high-frequency electrosurgical units. The intelligent high-frequency electrosurgical unit control system replaces open-loop coarse adjustment with automated closed-loop control. Through impedance angle calculation, active power feedback, peak factor adaptive control, and a pipelined program architecture, it achieves precise and stable adjustment of high-frequency output energy. The main structure of the intelligent high-frequency electrosurgical unit control system consists of a high-frequency energy generation module 1, an output module 2, an output sampling and detection module 3, a control module 4, a human-machine interface module 5, a host computer debugging module 6, and a power supply module 7. The power supply module 7 provides a stable and reliable power supply for the entire system. The high-frequency energy generation module 1, output module 2, output sampling and detection module 3, control module 4, human-machine interface module 5, and host computer debugging module 6 are all electrically connected to the power supply module 7. The control module 4, serving as the central hub of the system, coordinates the operation of various functional modules and achieves system-level control. It consists of an electrically isolated isolation zone 8 and a non-isolated zone 9, and employs a dual-processor architecture to complete drive control and signal sampling processing tasks. Simultaneously, the control module 4 incorporates a peak factor control counter 915, which automatically configures the interruption time of the PWM waveform based on the user-selected pure cut, mixed cut, or coagulation mode, achieving adaptive output for different peak factors. Furthermore, through a three-cycle pipelined program architecture, sampling, analysis, and control tasks are distributed to consecutive control cycles for parallel execution, significantly improving the system's real-time response speed and control frequency. The high-frequency energy generation module 1 generates high-frequency, high-power signals and, under the regulation of the control module 4, achieves adjustable output power. Its output terminal is connected to the output module 2 to transmit high-frequency energy to system peripherals. The output sampling and detection module 3 is connected to the system peripherals and is used to collect high-frequency output voltage and current signals in real time, and feeds the sampled data back to the control module 4. The isolation zone 8 in the control module 4 performs windowing processing and frequency domain analysis on the sampled data, calculates the voltage amplitude, current amplitude, and phase difference, and sends the data to the non-isolation zone 9 through the optocoupler isolation communication module 10. The non-isolation zone 9 calculates the active power on the load based on the received data, uses this active power as a feedback quantity, compares it with the set power, and generates a control quantity through the control algorithm to adjust the output voltage of the high-frequency energy generation module 1, thereby stabilizing the active power within the set threshold range when the tissue impedance changes. At the same time, the human-machine interaction module 5 is used by the operator to set the set power, select the working mode, and view the operating status, and the host computer debugging module 6 is used for data monitoring and performance optimization during system development.As can be seen, the technical solution of this invention, compared with the prior art, can perform precise power closed-loop control, thereby maintaining the active power stably within the set threshold range when the tissue impedance changes. It also supports flexible switching of multiple modes and improves the real-time performance and stability of the system response through a pipelined program architecture, ultimately improving surgical safety, treatment effect and reducing equipment cost.
