[0057] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily need to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0059] Figure 1 It is a schematic structural diagram of an ultrasonic energy adjustment device provided by an embodiment of the present invention, as Figure 1As shown, the ultrasonic energy adjustment device 01 includes: an adjustment control circuit 10, a voltage-controlled DC power supply circuit 20, and an inverter output circuit 30; the adjustment control circuit 10 is electrically connected to the voltage-controlled DC power supply circuit 20 and the inverter output circuit 30; the adjustment control circuit 10 is configured to obtain a target amplitude signal A0, a target frequency signal F0, a target period signal T0, and a target duty cycle signal D0, and output an amplitude control signal AC to the voltage-controlled DC power supply circuit 20 according to the target amplitude signal A0, and output a drive control signal to the inverter output circuit according to the target frequency signal F0, the target period signal T0, and the target duty cycle signal D0; the voltage-controlled DC power supply circuit 20 is also electrically connected to the inverter output circuit 30; the voltage-controlled DC power supply circuit 20 is configured to generate a DC voltage signal output to the inverter output circuit 30 according to the amplitude control signal; the inverter output circuit 30 is also electrically connected to the ultrasonic transducer 02; the inverter output circuit 30 is configured to generate an ultrasonic drive signal output to the ultrasonic transducer 02 according to the DC voltage signal and the drive control signal, so as to control the amplitude, frequency, period, and duty cycle of the ultrasonic energy output by the ultrasonic transducer 02.

[0060] Specifically, the target amplitude signal A0, the target frequency signal F0, the target period signal T0, and the target duty cycle signal D0 are control parameters of the ultrasonic drive signal, which can be used to correspondingly adjust the parameters of the ultrasonic drive signal, namely, amplitude, frequency, period, and duty cycle, so that when the ultrasonic transducer outputs ultrasonic energy, the amplitude, frequency, period, and duty cycle of the ultrasonic energy can be adjusted according to the ultrasonic drive signal, thereby realizing multi-parameter adjustment of the ultrasonic energy. When the adjustment control circuit 10 obtains the above control parameters, it can be obtained according to the feedback signal after the ultrasonic transducer 02 outputs ultrasonic energy. The feedback signal can be a biological characteristic signal of biological tissue or an ultrasonic drive signal. The biological characteristic signal can reflect the power magnitude of the ultrasonic energy, and combining the parameters of the reference ultrasonic drive signal can also reflect the power magnitude of the ultrasonic energy. Taking the feedback signal as the ultrasonic drive signal as an example, if it is determined that the power of the ultrasonic energy is small by combining the parameters of the reference ultrasonic drive signal within a detection time period, at least one of the following methods can be adopted based on the current control parameters: increasing the target amplitude signal A0, increasing the target frequency signal F0, decreasing the target period signal T0, and increasing the target duty cycle signal D0, so that the adjusted ultrasonic drive signal can increase the power of the ultrasonic energy; conversely, if it is determined that the power of the ultrasonic energy is large by combining the parameters of the reference ultrasonic drive signal within a detection time period, at least one of the following methods can be adopted based on the current control parameters: decreasing the target amplitude signal A0, decreasing the target frequency signal F0, increasing the target period signal T0, and decreasing the target duty cycle signal D0, so that the adjusted ultrasonic drive signal can decrease the power of the ultrasonic energy. The above describes the method of obtaining the target amplitude signal A0, the target frequency signal F0, and the target period signal T0 by using the ultrasonic drive signal as the feedback signal. In another feasible embodiment of the present invention, it can also be set according to the working time of the ultrasonic transducer 02. For example, the ultrasonic transducer 02 can be set to have multiple working modes, and the control parameters of each working mode are different. The switching of each working mode is realized according to the working time of each working mode, thereby realizing the acquisition of each control parameter. Or, in another feasible embodiment of the present invention, it can also be obtained according to the user's operation signal, that is, the user can input the adjustment signal of each control parameter to the adjustment control circuit 10 in real time during the process of the ultrasonic transducer 02 outputting ultrasonic energy. The above introduces several methods for obtaining control parameters, but it is not limited thereto. The embodiments of the present invention do not make specific limitations in this regard.

[0061] The adjustment control circuit 10 can be electrically connected to the voltage control terminal of the voltage-controlled DC power supply circuit 20. Then, the adjustment control circuit 10 can output a corresponding amplitude control signal to the voltage control terminal of the voltage-controlled DC power supply circuit 20 according to the target amplitude signal A0. When the target amplitude signal A0 is a digital signal, the amplitude control signal can be a corresponding analog signal. In this case, after converting the target amplitude signal A0 into an analog signal, the analog amplitude control signal can be output to the voltage-controlled DC power supply circuit 20, enabling the voltage-controlled DC power supply circuit 20 to adjust the magnitude of the output DC voltage signal according to the amplitude control signal. In a feasible embodiment, the amplitude control signal is a voltage signal, and the voltage-controlled DC power supply circuit 20 can amplify or reduce the voltage signal in proportion and output a corresponding DC voltage signal. Therefore, the amplitude of the DC voltage signal output by the voltage-controlled DC power supply circuit 20 can be adjusted by adjusting the voltage value of the amplitude control signal. It can be understood that the power input terminal of the voltage-controlled DC power supply circuit 20 can receive the DC power supply voltage VCC to supply power to the voltage-controlled DC power supply circuit 20. Among them, the voltage-controlled DC power supply circuit 20 can include a BUCK circuit and a BOOST circuit to achieve the boost function and the buck function respectively.

[0062] The adjustment control circuit 10 can also be electrically connected to the inverter output circuit 30, used to output a drive control signal to the inverter output circuit 30, and adjust the frequency, period, and duty cycle of the drive control signal according to the target frequency signal, target period signal, and target duty cycle signal. Among them, assuming that the period of the drive control signal is T1, and the stage where the drive control signal outputs an effective pulse within the period is T2, then the duty cycle D1 = T2 / T1, and the frequency F1 of the drive control signal is the frequency of the drive control signal outputting an effective pulse within the T2 stage. Among them, in the T2 stage where the drive control signal outputs an effective pulse, the drive control signal can alternately present an effective electrical level and an ineffective electrical level. In other stages except the T2 stage within a cycle T1, the drive control signal remains at the ineffective electrical level.

[0063] The inverter output circuit 30 inverts the DC voltage signal provided by the voltage-controlled DC power supply circuit 20 according to the drive control signal, so as to output an ultrasonic drive signal to the ultrasonic transducer 02. In this way, the inverter output circuit 30 can control the amplitude of the ultrasonic drive signal according to the amplitude of the DC voltage signal, and can adjust the instantaneous electric power output to the ultrasonic transducer 02 by adjusting the amplitude of the ultrasonic drive signal, so that the instantaneous ultrasonic power of the ultrasonic energy output by the ultrasonic transducer 02 can be adjusted. For example, when the instantaneous ultrasonic power is insufficient, the target amplitude signal A0 can be adjusted to increase the DC voltage signal output by the voltage-controlled DC power supply circuit 20, then the amplitude of the ultrasonic drive signal increases to increase the instantaneous electric power, and the amplitude of the ultrasonic energy can be increased to increase the instantaneous ultrasonic power, which can solve the problem that the instantaneous ultrasonic power is insufficient and effective tissue damage cannot be formed. Or, when the instantaneous ultrasonic power is too high, the target amplitude signal A0 can be adjusted to reduce the DC voltage signal output by the voltage-controlled DC power supply circuit 20, then the amplitude of the ultrasonic drive signal decreases to reduce the instantaneous electric power, and the amplitude of the ultrasonic energy can be reduced to reduce the instantaneous ultrasonic power, which can solve the problem that the instantaneous ultrasonic power is too high and the tissue damage is excessive.

[0064] Moreover, the inverter output circuit 30 can control the frequency, period, and duty cycle of the ultrasonic drive signal according to the frequency, period, and duty cycle of the drive control signal, and can also adjust the electric power of the ultrasonic drive signal. Thus, when the ultrasonic transducer 02 outputs ultrasonic energy, it can adjust the amplitude, frequency, period, and duty cycle of the ultrasonic energy according to the amplitude, frequency, period, and duty cycle of the ultrasonic drive signal, realizing the power adjustment of the ultrasonic energy. Since the ultrasonic transducer 02 will significantly heat up and get severely hot when outputting high-power ultrasonic energy, in this case, if the duration of the ultrasonic transducer 02 outputting high-power ultrasonic energy is long or it continuously outputs high-power ultrasonic energy, the piezoelectric effect of the ultrasonic transducer 02 will fail due to excessive temperature, and the high-temperature catheter will also damage the target tissue (such as renal artery tissue). Therefore, by setting the ultrasonic drive signal to have a duty cycle, the ultrasonic energy can have a certain duty cycle, enabling the ultrasonic transducer 02 to intermittently output high-power ultrasonic energy. And by adjusting the duty cycle of the ultrasonic drive signal, the intermittent time of the output ultrasonic energy can be adjusted, solving the problems of limited high-power output of the ultrasonic transducer 02 and the temperature rise of the target tissue, and being able to ensure that the temperature of the ultrasonic transducer 02 is within a suitable range while causing sufficient damage to the target tissue, without damaging the target tissue due to excessive temperature. In addition, by adjusting the period of the ultrasonic drive signal, the period of the ultrasonic energy can be adjusted, thereby adjusting the output dose of the ultrasonic energy. The output dose can be understood as the number of periods of the ultrasonic energy output within a preset time, for example, outputting 3 periods of ultrasonic energy or 10 periods of ultrasonic energy within 1 s. Thus, the damage range to the target tissue can be effectively controlled by adjusting the output dose of the ultrasonic energy. In addition, by adjusting the frequency of the sine signal, the frequency of the ultrasonic energy can be made to match the optimal operating frequency of the ultrasonic transducer 02, ensuring good operating performance of the ultrasonic transducer 02.

[0065] The ultrasonic energy regulation device provided by the embodiment of the present invention obtains a target amplitude signal, a target frequency signal, a target period signal, and a target duty cycle signal by setting an adjustment control circuit, and adjusts the amplitude control signal output to the voltage-controlled DC power supply according to the target amplitude signal, and adjusts the drive control signal output to the inverter output circuit according to the target frequency signal, the target period signal, and the target duty cycle signal. By setting a voltage-controlled DC power supply circuit, the magnitude of the DC voltage signal output to the inverter output circuit is adjusted according to the amplitude control signal, and by setting an inverter output circuit, the amplitude, frequency, period, and duty cycle of the ultrasonic drive signal output to the ultrasonic transducer are adjusted according to the DC voltage signal and the drive control signal. Therefore, when the ultrasonic transducer outputs ultrasonic energy, the amplitude, frequency, period, and duty cycle of the ultrasonic energy can be adjusted according to the amplitude, frequency, period, and duty cycle of the ultrasonic drive signal. The power regulation of the ultrasonic energy can be realized through the comprehensive adjustment of multiple parameters of the ultrasonic drive signal output by the ultrasonic energy regulation device. The problem that the instantaneous ultrasonic power is insufficient and effective tissue damage cannot be formed can be solved, and the problem that the instantaneous ultrasonic power is too high and the tissue damage is excessive can be solved. Moreover, the working temperature of the ultrasonic transducer can be effectively controlled so as not to cause high-temperature damage to the target tissue, the output dose of the ultrasonic energy can be adjusted to effectively control the damage range of the target tissue, and the good working performance of the ultrasonic transducer can be ensured. The multi-dimensional fine control of the ultrasonic transducer is realized, and through the mutual assistance and mutual restriction of multiple parameters, a fine tissue ablation effect is realized.

[0066] Optionally, Figure 2 is a schematic structural diagram of another ultrasonic energy regulation device provided by the embodiment of the present invention, as Figure 2As shown in the figure, the adjustment control circuit 10 includes: a controller 11, a digital frequency synthesis module 12, and a drive output module 13; the controller 11 is respectively connected to the voltage-controlled DC power supply circuit 20, the digital frequency synthesis module 12, and the drive output module 13; the controller 11 is used to obtain a target amplitude signal A0, a target frequency signal F0, a target period signal T0, and a target duty cycle signal D0; the controller 11 is further used to control the amplitude control signal output to the voltage-controlled DC power supply circuit 20 according to the target amplitude signal A0; the controller 11 is further used to control the frequency modulation signal output to the digital frequency synthesis module 12 according to the target frequency signal F0; and the controller 11 is further used to control the PWM modulation signal output to the drive output module 13 according to the target period signal T0 and the target duty cycle signal D0; the digital frequency synthesis module 12 is also electrically connected to the drive output module 13; the digital frequency synthesis module 12 is used to control the sine modulation signal output to the drive output module 13 according to the frequency modulation signal; the drive output module 13 is also electrically connected to the inverter output circuit 30; the drive output module 13 is used to control the drive control signal output to the inverter output circuit 30 according to the PWM modulation signal and the sine modulation signal.

[0067] Specifically, the controller 11 can be a processor with data processing functions, such as an MCU, a CPU, and a single-chip microcomputer, etc., and the embodiments of the present invention do not make specific limitations thereto. The target amplitude signal A0, the target frequency signal F0, the target period signal T0, and the target duty cycle signal D0 can be obtained through the controller 11. In the adjustment control circuit 10, the amplitude control signal output to the voltage-controlled DC power supply circuit 20 can be adjusted by the controller 11 according to the target amplitude signal A0. And when the target amplitude signal A0 is a digital signal, the amplitude control signal can be a corresponding analog signal. At this time, the controller 11 can convert the target amplitude signal A0 into a digital signal through the D / A conversion interface and then output the corresponding amplitude control signal to the voltage-controlled DC power supply circuit 20. When generating the drive control signal, the frequency modulation signal can be first output from the controller 11 to the digital frequency synthesis module 12, and the frequency modulation signal can be adjusted according to the target frequency signal F0, so that the digital frequency synthesis module 12 adjusts the frequency of the sine modulation signal according to the frequency modulation signal. At the same time, the controller 11 outputs the PWM modulation signal to the drive output module 13 and adjusts the period and duty cycle of the PWM modulation signal according to the target period signal T0 and the target duty cycle signal D0. Then when the drive output module 13 outputs the drive control signal to the inverter output circuit 30, the frequency, period, and duty cycle of the drive control signal can be adjusted according to the PWM modulation signal and the sine modulation signal.

[0068] Exemplarily, Figure 3This is a signal schematic diagram provided by an embodiment of the present invention. In the figure, S1 is a PWM modulation signal output by the controller 11 to the drive output module 13, S2 is a sine modulation signal output by the digital frequency synthesis module 12 to the drive output module 13, S3 is a drive control signal output by the drive output module 13 to the inverter output circuit 30, and S4 is an ultrasonic drive signal output by the inverter output circuit 30 to the ultrasonic transducer 02. As Figure 3 shown, the period of the PWM modulation signal S1 is T1, the duty cycle is T2 / T1, the period of the sine modulation signal S2 is T3, and the frequency is 1 / T3. During the T2 stage when the PWM modulation signal outputs a high level, the drive output module 13 can output the drive control signal S3 according to the sine modulation signal S2, and the frequency of the drive control signal is the same as that of the sine modulation signal S2. However, during the T4 stage when the PWM modulation signal S1 outputs a high level, even if the sine modulation signal S2 outputs a normal waveform, no effective pulse is output for the drive control signal, that is, the duty cycle and period of the drive control signal are the same as those of the PWM modulation signal S1. Thus, when the inverter output circuit 30 outputs the ultrasonic drive signal S4 according to the drive control signal S3 and the DC voltage signal, the duty cycle and period of the ultrasonic drive signal S4 are the same as those of the PWM modulation signal S1, and the frequency of the ultrasonic drive signal S4 during the T2 stage is the same as that of the sine modulation signal S2, and the amplitude of the ultrasonic drive signal S4 is related to the amplitude of the DC voltage signal. Thus, the magnitude of the amplitude control signal can be adjusted by the controller 11 to adjust the amplitude of the DC voltage signal output by the voltage-controlled DC power supply circuit 20, and further the amplitude of the ultrasonic drive signal S4 output by the inverter output circuit 30 can be adjusted; and by adjusting the frequency of the sine modulation signal S2 output by the digital frequency synthesis module 12 by the controller 11, the frequency of the drive control signal S3 output by the drive output module 13 can be adjusted, and further the frequency of the ultrasonic drive signal S4 output by the inverter output circuit 30 can be adjusted; and by adjusting the period and duty cycle of the PWM modulation signal S1 by the controller 11, the period and duty cycle of the drive control signal S3 output by the drive output module 13 can be adjusted, and further the period and duty cycle of the ultrasonic drive signal S4 output by the inverter output circuit 30 can be adjusted. The multi-parameter adjustment of the ultrasonic drive signal S4 can be realized, and thus the multi-parameter adjustment of the ultrasonic energy can be realized, making the adjustment of the ultrasonic energy more refined, which is beneficial to more precisely controlling the power of the ultrasonic energy and improving the working performance of the ultrasonic transducer 02.

Figure 4is a schematic diagram of the structure of another ultrasonic energy regulating device provided by an embodiment of the present invention, combined with reference Figure 3 and Figure 4 As shown, the inverter output circuit 30 includes an inverter module 31; the inverter module 31 includes a first transistor M1, a second transistor M2, a third transistor M3 and a fourth transistor M4; the first transistor M1 and the second transistor M2 are electrically connected in sequence between the positive terminal "+" and the negative terminal "-" of the voltage-controlled DC power supply circuit 20, and the third transistor M3 and the fourth transistor M4 are electrically connected in sequence between the positive terminal "+" and the negative terminal "-" of the voltage-controlled DC power supply circuit 20; the gates of the first transistor M1 and the fourth transistor M4 both receive the first drive control signal S31, and the gates of the second transistor M2 and the third transistor M3 both receive the second drive control signal S32; the drive output module 13 is also used to adjust the dead time of the first drive control signal S31 and the second drive control signal S32 according to the frequency of the sinusoidal modulation signal S2, so as to control the first transistor M1 and the second transistor M2 to be turned on in time-sharing manner, and to control the third transistor M3 and the fourth transistor M4 to be turned on in time-sharing manner.

[0070] Specifically, the inverter module 31 may be an H-bridge inverter circuit, wherein the drains of the first transistor M1 and the third transistor M3 may be electrically connected to the positive terminal “+” of the voltage-controlled DC power supply circuit 20, the source of the first transistor M1 and the drain of the second transistor M2 may be electrically connected to the first node a1, the source of the third transistor M3 and the drain of the fourth transistor M4 may be electrically connected to the second node a2, and the source of the second transistor M2 and the source of the fourth transistor M4 may be electrically connected to the negative terminal “-” of the voltage-controlled DC power supply circuit 20. Then the first node a1 and the second node a2 are the output terminals of the inverter module 31. In this way, the first transistor M1 and the fourth transistor M4 can be controlled to be turned on synchronously, the second transistor M2 and the third transistor M3 can be controlled to be turned on synchronously, and the first transistor M1 and the second transistor M2 can be controlled to be turned on asynchronously, so that the inverter module 31 can invert the DC voltage signal provided by the voltage-controlled DC power supply circuit 20, and output an AC signal corresponding to the amplitude of the DC voltage signal. The AC signal can be directly output to the ultrasonic transducer 02 as an ultrasonic drive signal, or, in another feasible embodiment, the AC signal is an initial AC signal, and the initial AC signal can be filtered and output to the ultrasonic transducer 02 as an ultrasonic drive signal. Therefore, by setting the gates of the first transistor M1 and the fourth transistor M4 to receive the first drive control signal S31, and setting the gates of the second transistor M2 and the third transistor M3 to receive the second drive control signal S32, the first transistor M1 and the fourth transistor M4 can be turned on or off synchronously under the control of the same drive control signal, and the second transistor M2 and the third transistor M3 can be turned on or off synchronously under the control of the same drive control signal, thereby realizing the inverter output function.

[0072] Specifically, the drive output module 13 can also be electrically connected to the output end of the inverter output circuit 30 to obtain the signal parameters of the ultrasonic drive signal. The signal parameters can include the amplitude, frequency, period, duty cycle, etc. of the ultrasonic drive signal. According to the signal parameters of the ultrasonic drive signal, the drive output module 13 can generate a synchronization pulse signal synchronized with the ultrasonic drive signal. The synchronization sampling trigger module 14 can generate a corresponding step signal according to the synchronization pulse signal. Then, according to the start and end times of the step signal, the controller 11 can determine the start time for obtaining the signal parameters of the ultrasonic drive signal and determine the end time for obtaining the signal parameters, so that the controller 11 can obtain the signal parameters of the ultrasonic drive signal within the start time and the end time. Among them, the controller 11 can obtain the signal parameters of the ultrasonic drive signal through the A / D conversion interface. The obtained signal parameters can be used to monitor the working state, working duration, etc. of the ultrasonic transducer 02, so as to control the ultrasonic energy adjustment device to stop working when the ultrasonic transducer 02 has faults such as aging. Among them, when the PWM modulation signal remains at a low level for a long time, while the drive output module 13 stops outputting the effective pulse of the drive control signal, it can also send a reset signal to the synchronization sampling trigger module 14 to reset the synchronization sampling trigger module 14, so that the step signal output by the synchronization sampling trigger module 14 is at a low level, so that the controller 11 stops obtaining the signal parameters of the ultrasonic drive signal.

[0073] In another feasible embodiment, the functions of the controller 11, the digital frequency synthesis module 12, the drive output module 13, and the synchronization sampling trigger module 14 can be implemented by a single functional module.

[0076] Specifically, the protection control circuit 40 can obtain the signal parameters of the ultrasonic drive signal output by the inverter output circuit 30. The signal parameters can include the amplitude and the effective value of the ultrasonic drive signal. When it is determined that the amplitude is too large and exceeds the safety threshold, and / or the effective value is too large and exceeds the safety threshold, the protection control circuit 40 outputs a corresponding protection control signal to the inverter output circuit 30, so that the inverter output circuit 30 stops working, that is, stops outputting the ultrasonic drive signal. When it is determined that both the amplitude and the effective value are within the safety threshold range, a corresponding protection control signal can be output to the inverter output circuit 30 to enable the inverter output circuit 30 to continuously output the ultrasonic drive signal, which can protect the ultrasonic transducer 02 from being damaged due to the abnormal output of the inverter output circuit 30. Exemplarily, with reference to Figure 3, it is possible to obtain the signal parameters of the T2 stage within at least one period, and output corresponding protection control signals according to the signal parameters within the T2 stage. When the amplitude of at least one period exceeds the safety threshold, and / or the effective value of at least one period exceeds the safety threshold, corresponding protection control signals are output to cause the inverter output circuit 30 to stop working. Alternatively, it is possible to obtain the signal parameters within a detection time period. When the amplitude of the ultrasonic drive signal is too large and exceeds the safety threshold within this detection time period, and / or the number of times the effective value is too large and exceeds the safety threshold exceeds a preset number of times, corresponding protection control signals are output to cause the inverter output circuit 30 to stop working. Or, it is also possible to output corresponding protection control signals to cause the inverter output circuit 30 to stop working when the number of times the amplitude is too large and exceeds the safety threshold within a detection time period, and / or the number of times the effective value is too large and exceeds the safety threshold exceeds a preset number of times.

[0077] Optionally, Figure 8 is a schematic structural diagram of another ultrasonic energy regulation device provided by an embodiment of the present invention. As Figure 8 shown, the ultrasonic energy regulation device 01 further includes: a detection circuit 50; the detection circuit 50 is electrically connected to the inverter output circuit 30, the regulation control circuit 10, and the protection control circuit 40 respectively; the detection circuit 50 is used to obtain the ultrasonic drive signal output by the inverter output circuit 30, and output the signal parameters of the ultrasonic drive signal to the regulation control circuit 10 and the protection control circuit 40. In this way, the regulation control circuit 10 and the protection control circuit 40 can obtain the signal parameters of the ultrasonic drive signal through the detection circuit 50. The signal parameters may include the voltage amplitude, current amplitude, voltage effective value, current effective value, period, frequency, duty cycle, etc. of the ultrasonic drive signal. Among them, when the regulation control circuit 10 includes a controller 11, a digital frequency synthesis module 12, a drive output module 13, and a synchronous sampling trigger module 14, the detection circuit 50 is connected to the controller 11 and the drive output module 13 respectively, and the connection method can be electrical connection and / or communication connection. When the regulation control circuit 10 includes a programmable logic module 15, a digital-to-analog conversion module 16, and an analog-to-digital conversion module 17, the detection circuit 50 is electrically connected and / or communication connected to the analog-to-digital conversion module 17.

[0078] Optionally, continue to refer to Figure 8 , the inverter output circuit 30 further includes: a drive module 32 and a resonance filtering module 33; the drive module 32 is electrically connected to the regulation control circuit 10 and the inverter module 31 respectively; the drive module 32 is used to obtain the drive control signal output by the regulation control circuit 10, and amplify and output the drive control signal to the inverter module 31; the resonance filtering module 33 is electrically connected to the inverter module 31 and the ultrasonic transducer 02 respectively; the resonance filtering module 33 is used to output an ultrasonic drive signal to the ultrasonic transducer 02 according to the initial AC signal output by the inverter module 31.

[0079] Specifically, the driving module 32 can amplify the driving control signals (i.e., the first driving control signal and the second driving control signal) provided by the adjustment control circuit 10, so that the amplified driving control signals can meet the control requirements of the transistors in the inverter module 31, ensuring that each transistor can be controlled to conduct or turn off. Among them, the initial AC signal output after the inverter module 31 inverts the DC voltage signal is a square-wave AC signal, such that the amplitude of the square-wave AC signal is related to the amplitude of the DC voltage signal. And when the DC voltage signal is inverted to generate a square-wave AC signal, each transistor in the inverter module 31 can conduct and turn off according to the frequency, period, and duty cycle of the driving control signals (i.e., the first driving control signal and the second driving control signal), and can correspondingly adjust the frequency, period, and duty cycle of the square-wave AC signal, making the frequency, period, and duty cycle of the square-wave AC signal related to the driving control signals. The resonance filtering module 33 can filter the initial AC signal output by the inverter module 31, retaining the fundamental wave component therein, i.e., the sine component, so that the ultrasonic driving signal output to the ultrasonic transducer 02 is a sine AC signal.

[0080] Exemplarily, referring to Figure 8 , when the inverter output circuit 30 includes the driving module 32, the driving module 32 is electrically connected to the protection control circuit 40. Then, when the amplitude and effective value of the ultrasonic driving signal are too large, the protection control signal output by the protection control circuit 40 can cause the driving module 32 to stop outputting the driving control signal to the inverter module 31, so that the driving module 32 can control the time for the inverter module 31 to output the initial AC signal according to the protection control signal output by the protection control circuit 40.

[0081] Based on the same inventive concept, an embodiment of the present invention further provides an ultrasonic energy adjustment method, which can be executed by the ultrasonic energy adjustment device provided in any embodiment of the present invention. Figure 9 is a flowchart of a method for adjusting an ultrasonic driving signal provided by an embodiment of the present invention, as Figure 9 shown, the method for adjusting the ultrasonic driving signal includes:

[0082] S110. Obtain a target amplitude signal, a target frequency signal, a target period signal, and a target duty cycle signal.

[0083] S120. Generate a DC voltage signal according to the target amplitude signal.

[0084] S130. Output a driving control signal according to the target frequency signal, the target period signal, and the target duty cycle signal.

[0085] S140. Generate an ultrasonic driving signal based on the DC voltage signal and the driving control signal, so that the ultrasonic transducer controls the amplitude, frequency, period, and duty cycle of the ultrasonic energy according to the ultrasonic driving signal.

[0086] Exemplarily, with reference to Figure 1 , when the ultrasonic energy adjustment device 01 includes an adjustment control circuit 10, a voltage-controlled DC power supply circuit 20, and an inverter output circuit 30, the target amplitude signal A0, the target frequency signal F0, the target period signal T0, and the target duty cycle signal D0 can be obtained through the adjustment control circuit 10. After obtaining the target amplitude signal A0, the target frequency signal F0, the target period signal T0, and the target duty cycle signal D0, the analog target amplitude signal A0 can be converted into a digital amplitude control signal. Thus, the voltage-controlled DC power supply circuit 20 can adjust the amplitude of the DC voltage signal according to the amplitude control signal, so that when the inverter output circuit 30 inverts the DC voltage signal to output an ultrasonic driving signal, the amplitude of the ultrasonic driving signal can be correspondingly adjusted, realizing the adjustment of the instantaneous electric power of the ultrasonic driving signal, and further the instantaneous power of the ultrasonic energy output by the ultrasonic transducer 02 can be adjusted. When the ultrasonic power is insufficient, the target amplitude signal A0 can be adjusted to increase the DC voltage signal output by the voltage-controlled DC power supply circuit 20, then the amplitude of the ultrasonic driving signal increases, making the instantaneous electric power increase, and the instantaneous ultrasonic power of the ultrasonic energy can be increased, which can solve the problem that the ultrasonic power is insufficient and effective tissue damage cannot be formed. Or, when the ultrasonic power is too high, the target amplitude signal A0 can be adjusted to decrease the DC voltage signal output by the voltage-controlled DC power supply circuit 20, then the amplitude of the ultrasonic driving signal decreases, making the instantaneous electric power decrease, and the instantaneous ultrasonic power of the ultrasonic energy can be decreased, which can solve the problem that the tissue damage is excessive due to too high ultrasonic power.

[0087] Meanwhile, the adjustment control circuit 10 adjusts the frequency, period, and duty cycle of the drive control signal according to the target frequency signal F0, target period signal T0, and target duty cycle signal D0. When the inverter output circuit 30 inversely converts the DC voltage signal provided by the voltage-controlled DC power supply circuit 20 to output an ultrasonic drive signal, it can control the frequency, period, and duty cycle of the ultrasonic drive signal according to the drive control signal. Among them, by setting the ultrasonic drive signal to have a duty cycle, the ultrasonic transducer 02 can intermittently output high-power ultrasonic energy, and by adjusting the duty cycle of the ultrasonic drive signal, the intermittent time of the output ultrasonic energy can be adjusted, solving the problems of limited high-power output of the ultrasonic transducer 02 and the temperature rise of the target tissue. It can ensure that while sufficient damage is formed to the target tissue, the temperature of the ultrasonic transducer 02 is also within a suitable range, and the target tissue will not be damaged due to excessive temperature. In addition, by adjusting the period of the ultrasonic drive signal, the output dose of the ultrasonic energy can be adjusted, thereby effectively controlling the damage range to the target tissue. In addition, by adjusting the frequency of the sine signal, the frequency of the ultrasonic energy can be matched with the optimal working frequency of the ultrasonic transducer 02, ensuring that the ultrasonic transducer 02 has good working performance.

[0088] The ultrasonic energy adjustment method provided by the embodiment of the present invention first obtains a target amplitude signal, a target frequency signal, a target period signal, and a target duty cycle signal, controls the DC voltage signal according to the target amplitude signal, and controls the drive control signal according to the target frequency signal, target period signal, and target duty cycle signal. Then, according to the DC voltage signal and the drive control signal, the amplitude, frequency, period, and duty cycle of the ultrasonic drive signal output to the ultrasonic transducer are adjusted, so that when the ultrasonic transducer outputs ultrasonic energy, it can adjust the amplitude, frequency, period, and duty cycle of the ultrasonic energy according to the amplitude, frequency, period, and duty cycle of the ultrasonic drive signal. Through the comprehensive adjustment of multiple parameters of the ultrasonic drive signal output by the ultrasonic energy adjustment device, the instantaneous ultrasonic power adjustment of the ultrasonic energy can be realized, the problem that effective tissue damage cannot be formed due to insufficient instantaneous ultrasonic power can be solved, and the problem that excessive tissue damage is caused by excessive instantaneous ultrasonic power can be solved. In addition, it can effectively control the working temperature of the ultrasonic transducer so that the target tissue is not damaged by high temperature, adjust the output dose of the ultrasonic energy to effectively control the damage range to the target tissue, and ensure that the ultrasonic transducer has good working performance, realizing multi-dimensional fine control of the ultrasonic energy. Through the mutual assistance and mutual restriction of multiple parameters, a fine tissue ablation effect is realized.

[0097] An embodiment of the present invention provides a method for adjusting a drive control signal. First, when generating a sine modulation signal, the frequency of the sine modulation signal is adjusted by controlling the sine modulation signal according to a target frequency signal. At the same time, when generating a PWM modulation signal, the period and duty cycle of the PWM modulation signal can be controlled according to a target period signal and a target duty cycle signal. Thus, when outputting the drive control signal, the frequency of the drive control signal can be adjusted according to the frequency of the sine modulation signal, and the period and duty cycle of the drive control signal can be adjusted correspondingly according to the period and duty cycle of the PWM modulation signal, realizing multi-parameter adjustment of the frequency, period, and duty cycle of the drive control signal. In this way, when outputting an ultrasonic drive signal according to a DC voltage signal and a drive control signal, the amplitude of the ultrasonic drive signal can be adjusted according to the amplitude of the DC voltage signal, and the frequency, period, and duty cycle of the ultrasonic drive signal can be adjusted according to the frequency, period, and duty cycle of the drive control signal, enabling multi-parameter adjustment of the amplitude, frequency, period, and duty cycle of the ultrasonic energy output by the ultrasonic transducer. Through the mutual assistance and mutual restriction of multiple parameters, multi-dimensional fine control of the ultrasonic transducer is achieved, and a fine tissue ablation effect is realized.
