[0045] The following Figures 1-4 The present application is further described in detail.

[0046] The embodiment of the present application discloses a method for controlling the power of an electrosurgical generator. The method can control the output power of the electrosurgical generator during use, and adjust the output power of the electrosurgical generator in real time as the protein denatures, thereby avoiding high-temperature carbonization of the tissue and increasing thermal injury.

[0047] An electrosurgical generator, also known as a high-frequency electrotome, is a device for performing surgical operations by generating high-frequency current. The core function is to heat the tissue using high-frequency current, thereby achieving tissue separation and coagulation, and achieving the purpose of cutting and hemostasis. When the electrosurgical generator (high-frequency electrotome) applies high-frequency current to the tissue during operation, as the water in the tissue evaporates, the protein denatures, and the impedance changes at any time, therefore, power control is needed to adjust the power output in real time, to avoid high-temperature carbonization of the tissue and increase thermal injury.

[0048] There are currently some methods for controlling the power of an electrosurgical generator. However, the existing power control methods do not adjust the power output according to the process of protein denaturation, which may result in poor coagulation of blood vessels. In order to better control the power output of the device and improve the coagulation effect of blood vessels, the present application provides a method for controlling the power of an electrosurgical generator.

[0049] Reference Figure 1 The method comprises the following steps:

[0050] S10, acquiring real-time sampling voltage data and real-time sampling current data, and calculating real-time impedance values and real-time power based on the real-time sampling voltage data and the real-time sampling current data.

[0051] Specifically, the sampling voltage data and the sampling current data collected in real time are acquired. The data acquisition method can acquire feedback data in real time through an ADC sampling circuit. The voltage and current data collected by the ADC sampling circuit are discrete data points. The real-time impedance values and the real-time power can be calculated based on the collected sampling voltage data and the sampling current data, so as to control the adjustment of the real-time power.

[0052] The electrosurgical generator is a device for performing surgery by generating high-frequency current. When the electrosurgical generator works to apply high-frequency current to the tissue, as the water in the tissue evaporates, the protein is denatured by heating, and the impedance changes at any time. Therefore, the power needs to be adjusted in real time, and it cannot work with fixed output power, so as to improve the effect of final blood vessel coagulation and reduce unnecessary damage.

[0053] S20, calculating the reference power according to the real-time impedance value and the preset impedance-power correspondence.

[0054] Specifically, due to the use of the electrosurgical generator, the evaporation of water in the tissue causes the protein to be denatured by heating, and the impedance changes. Different impedance values correspond to a reference power. Controlling the real-time power to reach the reference power can avoid high-temperature carbonization and increase heat damage as much as possible. The correspondence between the impedance value and the reference power is set in advance, as shown in the following table: Figure 2 The table shows the impedance value on the horizontal axis, with units of Ohms, and the power on the vertical axis, with units of Watts. According to the impedance-power correspondence diagram, the calculation method of the impedance-power correspondence can be represented as:

[0055] lgP REF =-K1+K2R-K3R 2 +K4R 3 ,

[0056] wherein K1, K2, K3 and K4 represent coefficients, K1, K3 and K4 are positive numbers less than 1, and K2 is a positive number less than 5; R represents the real-time impedance; P REF represents the reference power.

[0057] In the embodiments of the present application, K1 is taken as 0.094, K2 is taken as 2.527, K3 is taken as 0.8325, and K4 is taken as 0.04817. The calculation method of the impedance-power correspondence can be represented as:

[0058] lgP REF =-0.094++2.527R-0.8325R 2 +0.04817R 3 .

[0059] S30, adjusting the output value of the real-time power according to the reference power by using the phase-shifted full-bridge method, so that the output value of the real-time power is equal to the value of the reference power.

[0060] Specifically, the phase-shifted full-bridge is based on the pulse width modulation (PWM) technology and the operation of the full-bridge circuit. When the input direct current voltage passes through a proper conversion circuit, a high-frequency square wave signal is formed as a control signal of the phase-shifted full-bridge, which is called a carrier signal. In the phase-shifted full-bridge, when the carrier signal is at a high level, the switching elements on two diagonal lines in the phase-shifted full-bridge are turned on, and the switching elements on the other two diagonal lines are turned off; when the carrier signal is at a low level, the situation is reversed. By controlling the on and off time of the switching elements, the amplitude and phase of the output voltage can be adjusted, so that the purpose of adjusting the output power can be achieved. Through the phase-shifted full-bridge technology, the measured real-time power is adjusted to the reference power, so that the error between the real-time power and the reference power is 0, and finally the power adjustment is realized, and the adjusted power is output to the tissue.

[0061] In the scheme of the present application, the real-time impedance value and power can be calculated by acquiring the sampling voltage and sampling current in real time. Considering that the power needs to be adjusted according to the protein denaturation process during the use of the instrument to avoid tissue injury and improve the blood vessel coagulation effect, the real-time power is adjusted to the reference power output through the phase-shifted full-bridge technology. The whole power adjustment process is adjusted according to the power output of the load impedance, and the output power is dynamically changed according to the protein denaturation process within a safe range, so as to reduce tissue damage.

[0062] In one embodiment, the way of calculating the real-time impedance value and the real-time power according to the real-time sampling voltage data and the real-time sampling current data can be specifically performed as follows:

[0063] First, the voltage effective value, the current effective value and the phase difference are calculated and obtained according to the real-time sampling voltage data and the real-time sampling current data. The calculation formula of the voltage effective value, the current effective value and the phase difference can be represented as follows:

[0064]

[0065] θ=V θ -I θ

[0066] wherein V n represents the real-time sampling voltage data, I n represents the real-time sampling current data, N represents the total number of sampling data points, V rms represents the voltage effective value, I rms represents the current effective value, θ represents the phase difference, V θ represents the voltage phase, and I θ represents the current phase.

[0067] After that, the real-time impedance value and the real-time power are calculated according to the voltage effective value, the current effective value and the phase difference, and the calculation method of the calculated real-time impedance value and the real-time power can be represented as:

[0068]

[0069] P = V rms * rms *cos(θ),

[0070] Wherein, R represents the real-time impedance value, P represents the real-time power, V rms represents the voltage effective value, I rms represents the current effective value, and θ represents the phase difference.

[0071] In the scheme of the present application, the impedance value dynamically changes during the protein denaturation process, the real-time voltage and current data are collected to calculate the real-time impedance value and the real-time power, the corresponding reference power is obtained through the real-time impedance value, and the calculated real-time power is adjusted to the reference power output, so as to achieve the purpose of power control, reduce tissue damage and improve the use effect of the instrument.

[0072] In one embodiment, the electrosurgical generator power control system comprises an FPGA module; the output value of the real-time power is adjusted according to the reference power in a phase-shifted full-bridge method, and the mode that the output value of the real-time power is equal to the value of the reference power can be specifically implemented as:

[0073] First, the reference power and the real-time power are input into a preset PID control algorithm, and the PID control amount is calculated and output, and the calculation method of the PID control amount output by the PID control algorithm can be represented as:

[0074] P e =P REF -P

[0075] P D =P e -P e(n-1)

[0076] Out=P K *P e +P I *∑P e +P D *P D

[0077] Wherein, P REF represents the reference power, P represents the real-time power, P e represents the power error, P D represents the power difference, and PID Krepresents a proportional coefficient of a preset PID control algorithm, PID I represents an integral coefficient of a preset PID control algorithm, PID D represents a differential coefficient of a preset PID control algorithm.

[0078] Then, the calculated PID control quantity is input into the FPGA module, and the FPGA module is controlled to generate a PWM signal with a phase shift difference; since the adjustment power adopts a phase-shift full-bridge method, the phase-shift full-bridge method is based on a pulse width modulation (PWM) technology and a full-bridge circuit, and therefore, the FPGA module is used to generate a PWM signal with a phase shift difference according to the output PID control quantity, so as to use the phase-shift full-bridge method to adjust the real-time power in real time. Finally, the phase-shift full-bridge method is used to adjust the output value of the real-time power according to the PWM signal with the phase shift difference, so that the output value of the real-time power is equal to the value of the reference power.

[0079] The error between the real-time power and the reference power is calculated by the PID control algorithm, so that the adjustment can be performed in real time. The output Out of the PID algorithm is the output PID control quantity. When there is an error between the real-time power and the reference power, the calculated power error is not 0, and the final output Out value is also not 0, and then the real-time power needs to be adjusted. When the adjusted real-time power reaches the reference power, the final output value of the PID control algorithm is 0, and then no adjustment is needed, and the output adjusted power can be output.

[0080] In the scheme of the present application, the PID control algorithm and the phase-shift full-bridge method are combined to control the real-time output power. The phase-shift full-bridge is a high-efficiency and stable circuit topology structure. In combination with the PID control algorithm, the output power is controlled according to the real-time acquired voltage and current data, so that the output power can be dynamically adjusted according to the process of protein temperature denaturation, and the coagulation effect of blood vessels after use of the device is improved.

[0081] Figure 1 is a flowchart of the method for controlling the power of the electrosurgical generator in one embodiment. It should be understood that, although the steps in the flowchart of Figure 1 are shown in a sequential order, such that each subsequent step is performed only after the previous step has been completed, the steps do not have to be performed in this order. Unless the context clearly indicates otherwise, the steps can be performed in any order, and the steps can be performed in an overlapping manner. Furthermore, Figure 1 at least some of the steps in the flowchart of may include multiple sub-steps or multiple stages, and the sub-steps or stages do not have to be performed at the same time, but can be performed at different times. Furthermore, the order of the sub-steps or stages does not have to be sequential, but can be performed in an overlapping manner with other steps or sub-steps or stages of other steps.
