It can be understood that the illustrative embodiments of the present disclosure include but are not limited to related methods, devices and systems, and the specific embodiments described herein are only for the purpose of explaining the present application, but not limiting the present application. In addition, for the purpose of description, only the parts related to the present application are shown in the drawings, not all the structures or processes.

[0053] The following will describe the embodiments of the present application by specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosure. Although the description of the present application will be introduced in combination with the preferred embodiments, it does not mean that the features of the present application are limited to the embodiments. On the contrary, the purpose of introducing the present application in combination with the embodiments is to cover other options or modifications that can be extended based on the claims of the present application. In order to provide a deep understanding of the present application, many specific details will be included in the following description. The present application can also be implemented without using these details. In addition, in order to avoid confusion or obscure the focus of the present application, some specific details will be omitted in the description. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0054] In addition, various operations will be described as multiple discrete operations, in a manner that is most helpful in understanding the illustrative embodiments; however, the order of description is not intended to be construed as a requirement, nor does it imply that these operations are ordered in that order. In particular, these operations need not be performed in the order presented.

[0055] Unless otherwise defined, the terms "comprises", "comprising", and "including" are synonymous with the term "comprising".

[0056] The term "and / or", used herein only to describe association relationship of associated objects, means that there can be three relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B, and the existence of B alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after. The phrase "A / B" represents "A or B".

[0057] In the present application, "at least one" means one or more, and "multiple" means two or more. "At least one of the following" or the like means any combination of the items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

[0058] In various embodiments of the present application, the size of the sequence number of the above-mentioned processes does not mean the order of execution, and the execution order of the processes should be determined by their functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0059] The prior art single acquisition method has good regulation ability and output stability in normal working state, but the structure design of the system usually depends on a single acquisition path, that is, a set of voltage sampling and current sampling circuit. This architecture has obvious safety hazards: once the sampling circuit has hardware failure, such as sampling resistor damage, poor signal path contact or sensor drift, etc., the acquired voltage or current value may be severely distorted.

[0060] In the existing energy surgical system, when the acquisition signal is wrong, the control system will still execute the power adjustment strategy according to the wrong electric parameter data. For example, if the output power is low, the system will mistakenly think that the current power is insufficient, and will continue to increase the output energy until the sampling value matches the target value, which may eventually cause the actual output power to far exceed the target set by the doctor. Without effective redundancy protection or cross-validation mechanism, this error behavior is extremely easy to cause the patient to receive excessive energy, causing tissue burn, overheating damage, or even irreversible physiological damage, which poses a major threat to the patient's life safety.

[0061] Figure 1 A structure block diagram of an energy surgical host system with protection function is shown in an embodiment of the present application, as shown in the figure, the system 10 includes an energy surgical host high-voltage direct-current power supply 11, an energy surgical host output drive circuit 12, a first energy surgical host output sampling circuit 13, a second energy surgical host output sampling circuit 14, an energy surgical host first controllable processing module 15, and an energy surgical host second controllable digital module 16. Figure 1

[0062] In one embodiment, the energy surgical host high-voltage direct-current power supply 11 can be referred to as high-voltage direct-current power supply, the energy surgical host output drive circuit 12 can be referred to as output drive circuit, the first energy surgical host output sampling circuit 13 can be referred to as first output sampling circuit, the second energy surgical host output sampling circuit 14 can be referred to as second output sampling circuit, the energy surgical host first controllable processing module 15 can be referred to as controllable processing module, and the energy surgical host second controllable digital module 16 can be referred to as second controllable digital module. Those skilled in the art can understand that other modules with energy surgical host can also remove the energy surgical host subject from the short name.

[0063] ​The first energy surgical host output sampling circuit is connected to the output end 17 of the energy surgical host, and includes a first voltage sensor and a first current sensor and a first analog-to-digital converter, for collecting the first voltage and the first current signal of the output end of the energy surgical host and converting them into first digital sampling data for the first controllable processing module of the energy surgical host; the first controllable processing module of the energy surgical host outputs a control signal to the energy surgical host output driving circuit based on the first digital sampling data, so as to control the energy output of the energy surgical host high-voltage direct-current power supply and the output end of the energy surgical host, and calculate the output power of the output end of the energy surgical host high-voltage direct-current power supply; the second energy surgical host output sampling circuit is connected to the output end of the energy surgical host, and includes a second voltage sensor and a second current sensor and a second analog-to-digital converter, for collecting the second voltage and the second current signal of the output end of the energy surgical host and converting them into second digital sampling data for the second controllable digital module of the energy surgical host; the second controllable digital module of the energy surgical host is connected to the first controllable processing module of the energy surgical host, for comparing the first digital sampling data with the second digital sampling data, and outputting the sampling deviation value between the first digital sampling data and the second digital sampling data; when the sampling deviation value between the first digital sampling data and the second digital sampling data exceeds a first preset threshold, the energy supply of the high-voltage direct-current power supply to the output end of the energy surgical host is cut off, and the first controllable processing module of the energy surgical host closes the output of the energy surgical host high-voltage direct-current power supply by controlling the enable pin of the energy surgical host high-voltage direct-current power supply, so as to cut off the energy supply to the output end of the energy surgical host high-voltage direct-current power supply.

[0064] In one embodiment, the second controllable digital module for comparing the first digital sampling data with the second digital sampling data further includes: comparing the power deviation value of the first output power based on the first digital sampling data and the second output power based on the second digital sampling data; when the comparison result shows that the power deviation value of the first output power based on the first digital sampling data and the second output power based on the second digital sampling data exceeds a second preset threshold, the first controllable processing module closes the output of the high-voltage direct-current power supply by controlling the enable pin of the high-voltage direct-current power supply.

[0065] Specifically, one sampling data or power can be divided by the other sampling data or power, and when the proportional value is greater than 10% relative to the standard data such as 1:1 difference, it is determined that the deviation value is too large, and the ratio method, difference method, logarithmic ratio method, etc. can be used.

[0066] Figure 2A structure block diagram of an energy surgical host system with protection function is shown in Figure 1, which shows one embodiment of the present application. Figure 2 As shown in Figure 1, the energy surgical host system with protection function further comprises a user interaction module 19 and an output isolation transformer 18, wherein the output of the energy surgical host high-voltage DC power supply is connected to a primary side winding of the output isolation transformer via an energy surgical host output drive circuit, and a secondary side of the output isolation transformer is connected to the output of the energy surgical host.

[0067] In one embodiment, the user interaction module is a module through which a user (e.g., a doctor) inputs target parameters (power, maximum current, voltage, etc.), which are sent to the first controllable processing module of the energy surgical host by an interface as core control instructions.

[0068] In one embodiment, the energy surgical host output drive circuit can be a MOSFET, which specifically can include four power MOS tubes to drive the isolation transformer T1 after integrating the high-voltage DC power supply and the PWM control signal; the output of the drive isolation transformer T1 is to the "ACTIVE" and "RETURN" two ports for connecting the load.

[0069] The present application adopts two sets of redundant parameter acquisition circuits to realize abnormality detection and safe energy-off control through redundant voltage, current acquisition and power calculation comparison.

[0070] In one embodiment, the energy surgical host high-voltage DC power supply provides the main power source; has an Enable pin, which is controlled by the double safety logic control of the first controllable processing module of the energy surgical host and the second controllable digital module of the energy surgical host; if the detection is abnormal or the sampling data deviates seriously, the system pulls down the Enable to prevent the output from losing control. If the first energy surgical host output sampling circuit fails (e.g., the voltage sampling is extremely high or the power sampling is extremely high), the first controllable processing module of the energy surgical host will continuously increase the output in pursuit of the target power; the second controllable digital module of the energy surgical host detects that the abnormal difference exceeds the standard through the second set of sampling; the system immediately pulls down the Enable to cause the high-voltage power supply to shut down, avoiding harming the patient; and the system reflects the high safety fault tolerance in the medical scene.

[0071] In one embodiment, the energy surgical host output drive circuit is connected to the energy surgical host high-voltage DC power supply, includes a plurality of power switching devices to constitute an inverter circuit, and the output of the energy surgical host output drive circuit is connected to a primary side winding of the output isolation transformer; the output pin of the first controllable processing module of the energy surgical host is electrically connected to the control end of the power switching device, for controlling the conduction and turn-off of the power switching device to generate an alternating current in the primary side winding.

[0072] In one embodiment, the system further comprises: the user interaction module is connected with the energy surgical host first controllable processing module, for receiving user input output power setting value and working mode instruction, and displaying working state information to the user; the energy surgical host first controllable processing module adjusts the power parameter of energy output according to the user setting received by the user interaction module.

[0073] In one embodiment, the output end connected to the secondary side of the output isolation transformer comprises an active electrode 171 and a return electrode 172, for connecting to surgical instruments to apply the energy output to patient tissue.

[0074] In one embodiment, comprising: the first energy surgical host output sampling circuit and the second energy surgical host output sampling circuit each comprise a voltage sensor across the active electrode and the return electrode, and a current sensor in series in the output loop, the first energy surgical host output sampling circuit detects the first output voltage and the first output current of the output end, and the second energy surgical host output sampling circuit detects the second output voltage and the second output current of the output end.

[0075] In one embodiment, the energy surgical host first controllable processing module calculates the first output power value of the output end by multiplying the first voltage value and the first current value in the first digital sampling data, and sends the first output power value to the energy surgical host second controllable digital module through the communication interface.

[0076] In one embodiment, the energy surgical host second controllable digital module receives the first output power value calculated by the energy surgical host first controllable processing module; the energy surgical host second controllable digital module calculates the second output power value according to the second digital sampling data; the energy surgical host second controllable digital module compares the first output power value and the second output power value to obtain a comparison result.

[0077] In one embodiment, comprising: the energy surgical host high-voltage DC power supply is provided with an enable control pin and is electrically connected to the control output end of the energy surgical host first controllable processing module; when the energy surgical host first controllable processing module sends a shutdown signal to the enable control pin, the energy surgical host high-voltage DC power supply stops supplying power to the output end.

[0078] In one embodiment, the energy surgical host first controllable processing module and the energy surgical host second controllable digital module are connected through a high-speed serial communication interface to realize real-time transmission and comparison of the first digital sampling data and the second digital sampling data.

[0079] In one embodiment, the preset threshold is stored in the memory of the energy surgical host first controllable processing module or the energy surgical host second controllable digital module, and can be set and adjusted through the user interaction module to adapt to different safety control requirements.

[0080] In one embodiment, through the dual-channel redundant acquisition and comparison mechanism of the energy surgical host first controllable processing module and the energy surgical host second controllable digital module, when the acquisition data of any channel is abnormal, the other channel can detect and trigger the energy surgical host high-voltage DC power supply to be disabled, thereby improving the fault tolerance safety of the system.

[0081] In one embodiment, the energy surgical host first controllable processing module can be an FPGA module or other modules with the same function, and the energy surgical host second controllable digital module can be a DSP or other modules with the same function.

[0082] In one embodiment, if the energy surgical host first controllable processing module is an FPGA (field programmable gate array), the functions include: receiving UI module setting parameters; outputting PWM signal to control the driving circuit composed of MOSFET tube; realizing closed-loop control of output power; interacting with DSP for data and abnormal comparison; controlling the Enable end of the high-voltage power supply.

[0083] In one embodiment, the DSP processor is responsible for independent calculation of power, and feeds back the second channel sampling data to the FPGA; if the error found by comparison is greater than the set threshold, the Enable pin of the high-voltage power supply is pulled low to make the output invalid (safety power failure).

[0084] The application includes a user interaction module, an FPGA, an energy output isolation transformer T1, a driving circuit of the energy output isolation transformer T1, an output current sampling sensor I_sensor1 of a first set of acquisition circuits, an output voltage sampling circuit_1 of the first set of acquisition circuits, a current sampling ADC of the first set of acquisition circuits, a voltage sampling ADC of the first set of acquisition circuits, an output current sampling sensor I_sensor2 of a second set of acquisition circuits, an output voltage sampling circuit_2 of the second set of acquisition circuits, a processor DSP with a multi-channel ADC of the second set of acquisition circuits, and a high-voltage DC power supply with output enable control.

[0085] In one embodiment, the user interaction module is responsible for the man-machine interaction function, and transmits the output power and other parameter information set by the doctor to the FPGA for execution. The functions of the FPGA are as follows: first, receiving the control parameter information transmitted by the UI module, including power, maximum voltage, maximum current, start signal, etc.; second, outputting the power control signal to the driving circuit; third, acquiring the output voltage and current signals through the first set of acquisition circuits, calculating the phase difference θ of the voltage and current signals, and then calculating the real output power by multiplying cosθ. According to the comparison between the power value and the power value set by the doctor, the control signal is changed to make the output consistent with the setting. Fourth, sending the voltage and current data of the first set of acquisition circuits to the DSP. Fifth, receiving the voltage and current data of the second set of acquisition circuits sent by the DSP for comparison. If the deviation value is greater than the first set threshold (for example, 10%), the output is stopped, and the enable pin of the high-voltage DC power supply is disabled; if the deviation is less than or equal to the first set threshold (for example, 10%).

[0086] The driving circuit of the energy output isolation transformer T1 integrates the control signal of the FPGA and the high-voltage output of the high-voltage DC power supply to drive the output isolation transformer T1.

[0087] The functions of the DSP are as follows: first, acquiring the output voltage and current signals through the second set of acquisition circuits, calculating the phase difference θ of the voltage and current signals, and then calculating the real output power by multiplying cosθ. Second, sending the voltage and current data of the second set of acquisition circuits to the FPGA. Third, receiving the voltage and current data of the first set of acquisition circuits sent by the FPGA for comparison. If the deviation is greater than the threshold, the enable pin of the high-voltage DC power supply is disabled.

[0088] If the hardware of the first set of acquisition circuits fails, for example, the voltage acquisition circuit fails, and the acquired voltage value is very low, if there is no second set of acquisition circuits for comparison and verification, the FPGA will always increase the output energy in order to reach the set value, which will cause danger to the safety of the patient. In the present application, if the hardware of the first set of acquisition circuits with FPGA as the acquisition core fails, the DSP will find that the data does not match, and the output will be stopped before the accident occurs to ensure the safety of the patient.

[0089] In another embodiment, when a certain hardware (such as a voltage sampling circuit) of the first sampling channel fails, causing the voltage signal to be lower, the FPGA may mistakenly believe that the output is insufficient and continuously increase the power, thereby causing the actual energy to exceed the standard. At this time, the DSP can discover the power deviation based on the second channel sampling, and if it exceeds the second set threshold set by the system, it will trigger the Enable pin of the high-voltage power supply to cooperate with the FPGA to shut down, so that the system automatically stops the energy before the abnormality occurs, thereby ensuring the safety of the patient during the operation.

[0090] In an embodiment, the system supports setting a power deviation tolerance threshold (for example, within ±10%) by the user through the UI module, which can be dynamically written to the internal registers of the FPGA and DSP, used to adjust the fault tolerance range of the power comparison. This flexible configuration capability improves the system's ability to adapt to different surgical environments and individual differences of patients, enhancing the safety and versatility of the device.

[0091] The technical scheme provided in the present application can solve the output miscontrol risk problem caused by relying on a single output sampling path in the existing energy surgical operation host. In the traditional scheme, the system only calculates and controls the output power based on a set of voltage and current sampling signals, and once the sampling circuit fails (such as sensor damage, sampling value drift, or circuit open), the control logic will make a mistake based on the wrong data, which may cause the actual output energy to far exceed the doctor's set value, and in severe cases, it will cause irreversible tissue damage to the patient, lacking basic fault tolerance protection capability. The present application constructs a dual-channel redundant sampling architecture, that is, two independent voltage and current sampling paths are introduced, which are connected to the FPGA and DSP modules respectively, and each independently completes the output power calculation. During system operation, the first channel data is used by the FPGA for real-time closed-loop control, and the second channel data is independently verified by the DSP. When there is a significant deviation in the power calculation value between the two channels, the system automatically judges the sampling anomaly through comparison logic, thereby triggering the energy control of the high-voltage DC power supply, ensuring that the system can still reliably stop output under the condition of sampling hardware failure or signal distortion, effectively preventing energy out of control from causing harm to the patient.

[0092] In addition, the technical scheme of the present application also supports setting a configurable safety tolerance threshold through the UI module, which can flexibly adjust the power comparison tolerance range according to different surgical needs and individual differences of patients. This configuration not only improves the individual adaptability of the system, but also enhances the safety and versatility of the product in clinical application.

[0093] The energy surgical host computer system with the protection function provided by the embodiment of the present application, through the strategy of "main control + redundancy check + difference comparison + automatic power interruption", not only significantly improves the accuracy, reliability and fault tolerance of the energy surgical host computer in power control, but also realizes the safe closed loop design at the system level, solves the problem that the prior art cannot reliably identify abnormalities and timely interrupt the output under hardware failure.

[0094] The description of the present application is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present application to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments are chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application for various embodiments with various modifications as are suited to the particular use contemplated.
