[0057] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0058] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0059] Figure 1 is a schematic diagram of the structure of an ultrasonic energy regulating device provided by an embodiment of the present invention, such as Figure 1As shown, the ultrasonic energy regulating device 01 includes: a regulating control circuit 10, a voltage-controlled DC power supply circuit 20 and an inverter output circuit 30; the regulating control circuit 10 is electrically connected to the voltage-controlled DC power supply circuit 20 and the inverter output circuit 30; the regulating control circuit 10 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, 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 an amplitude control signal AC to the voltage-controlled DC power supply circuit 20 according to the target frequency signal F0, the target period signal T0 and the target duty cycle signal D0. The duty cycle signal D0 outputs a driving control signal to the inverter output circuit; 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 used 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 used to generate an ultrasonic driving signal output to the ultrasonic transducer 02 according to the DC voltage signal and the driving 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 adjust the parameters of the ultrasonic drive signal, namely, the 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-mentioned control parameters, it can obtain them according to the feedback signal after the ultrasonic transducer 02 outputs the ultrasonic energy. The feedback signal can be a biological characteristic signal of a biological tissue or an ultrasonic drive signal. The biological characteristic signal can reflect the power of the ultrasonic energy, and can reflect the power of the ultrasonic energy in combination with the parameters of the reference ultrasonic drive signal. Taking the feedback signal as an ultrasonic drive signal as an example, if it is determined that the power of the ultrasonic energy is small in combination with the parameters of the reference ultrasonic drive signal within a period of detection time, at least one of increasing the target amplitude signal A0, increasing the target frequency signal F0, reducing the target period signal T0 and increasing the target duty cycle signal D0 can be adopted on the basis of the current control parameters, 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 in combination with the parameters of the reference ultrasonic drive signal within a period of detection time, at least one of reducing the target amplitude signal A0, reducing the target frequency signal F0, increasing the target period signal T0 and reducing the target duty cycle signal D0 can be adopted on the basis of the current control parameters, so that the adjusted ultrasonic drive signal can reduce the power of the ultrasonic energy. The above describes a method of using the ultrasonic drive signal as a feedback signal to obtain the target amplitude signal A0, the target frequency signal F0, and the target period signal T0. In another feasible embodiment of the present invention, the parameters 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. Alternatively, in another feasible embodiment of the present invention, it can also be acquired 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. Several control parameter acquisition methods are introduced above, but are not limited to this, and the embodiments of the present invention do not specifically limit this.

[0061] The regulating control circuit 10 can be electrically connected to the voltage control end of the voltage-controlled DC power supply circuit 20, and the regulating control circuit 10 can output the corresponding amplitude control signal to the voltage control end 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. At this time, the target amplitude signal A0 can be converted into an analog signal, and the amplitude control signal of the analog quantity can be output to the voltage-controlled DC power supply circuit 20, so that the voltage-controlled DC power supply circuit 20 can 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 equal proportion and output the corresponding DC voltage signal, so 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 end of the voltage-controlled DC power supply circuit 20 can receive the DC power supply voltage VCC to power the voltage-controlled DC power supply circuit 20. The voltage-controlled DC power supply circuit 20 may include a BUCK circuit and a BOOST circuit to respectively implement a boost function and a buck function.

[0062] The regulating control circuit 10 can also be electrically connected to the inverter output circuit 30, and is 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, the target period signal and the target duty cycle signal. Wherein, assuming that the period of the drive control signal is T1, and the stage in which the drive control signal outputs a valid 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 a valid pulse within the T2 stage. Wherein, in the T2 stage in which the drive control signal outputs a valid pulse, the drive control signal can be presented as a valid level and an invalid level that can appear alternately, and in a period T1, except for the other stages of the T2 stage, the drive control signal remains at an invalid 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 driving control signal to output the ultrasonic driving signal to the ultrasonic transducer 02. In this way, the inverter output circuit 30 can control the amplitude of the ultrasonic driving 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 driving signal, so as to adjust the instantaneous ultrasonic power of the ultrasonic energy output by the ultrasonic transducer 02. 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, and the amplitude of the ultrasonic driving signal increases, so that the instantaneous electric power increases, 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. Alternatively, 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. The amplitude of the ultrasonic drive signal is reduced, so that the instantaneous electric power is reduced. The ultrasonic energy amplitude can be reduced, thereby reducing the instantaneous ultrasonic power, which can solve the problem of excessive tissue damage caused by excessive instantaneous ultrasonic power.

[0064] Furthermore, 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, so that 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 to achieve power regulation of the ultrasonic energy. Since the ultrasonic transducer 02 will heat up significantly when outputting high-power ultrasonic energy, the heat generation is serious. In this case, if the ultrasonic transducer 02 outputs high-power ultrasonic energy for a long time or continuously outputs high-power ultrasonic energy, the ultrasonic transducer 02 will fail due to the high temperature, and the piezoelectric effect will fail, 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, so that 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 outputting ultrasonic energy can be adjusted, which solves the problem of limited high-power output of the ultrasonic transducer 02 and the temperature rise of the target tissue, and can form sufficient damage to the target tissue while ensuring that the temperature of the ultrasonic transducer 02 is within a suitable range, and will not damage the target tissue due to excessive temperature. In addition, by adjusting the cycle of the ultrasonic drive signal, the cycle of the ultrasonic energy can be adjusted, so that the output dose of the ultrasonic energy can be adjusted. The output dose can be understood as the number of cycles of outputting ultrasonic energy within a preset time, such as outputting 3 cycles of ultrasonic energy or 10 cycles of ultrasonic energy within 1s, so that the damage range of the target tissue can be effectively controlled by adjusting the output dose of the ultrasonic energy. In addition, by adjusting the frequency of the sinusoidal signal, the frequency of the ultrasonic energy can be matched with the optimal operating frequency of the ultrasonic transducer 02, which can ensure that the ultrasonic transducer 02 has good working performance.

[0065] The ultrasonic energy regulating device provided by the embodiment of the present invention obtains the target amplitude signal, the target frequency signal, the target period signal and the target duty cycle signal by setting the regulating 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, and adjusts the magnitude of the DC voltage signal output to the inverter output circuit according to the amplitude control signal by setting the voltage-controlled DC power supply circuit, and adjusts the amplitude, frequency, period and duty cycle of the ultrasonic drive signal output to the ultrasonic transducer according to the DC voltage signal and the drive control signal by setting the inverter output circuit, so that the ultrasonic transducer can adjust the amplitude, frequency, period and duty cycle of the ultrasonic drive signal according to the amplitude of the ultrasonic drive signal when outputting ultrasonic energy. The amplitude, frequency, period and duty cycle of the ultrasonic energy can be adjusted by the ultrasonic energy regulating device, and the power regulation of the ultrasonic energy can be achieved through the comprehensive adjustment of multiple parameters of the ultrasonic driving signal output by the ultrasonic energy regulating device. The problem that the instantaneous ultrasonic power is insufficient and cannot form effective tissue damage, as well as the problem that the instantaneous ultrasonic power is too high and causes excessive tissue damage can be solved. 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 to the target tissue, and the ultrasonic transducer can be ensured to have good working performance, thereby realizing multi-dimensional refined control of the ultrasonic transducer, and realizing refined tissue ablation effect through the mutual assistance and mutual restriction of multiple parameters.

[0066] Optional, Figure 2 FIG. 1 is a schematic diagram of the structure of another ultrasonic energy regulating device provided in an embodiment of the present invention. Figure 2As shown, the regulation control circuit 10 includes: a controller 11, a digital frequency synthesis module 12 and a drive output module 13; the controller 11 is connected to the voltage-controlled DC power supply circuit 20, the digital frequency synthesis module 12 and the drive output module 13 respectively; the controller 11 is used to obtain the target amplitude signal A0, the target frequency signal F0, the target period signal T0 and the target duty cycle signal D0; the controller 11 is also 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 also used to control the output to the digital frequency synthesis module according to the target frequency signal F0. The controller 11 is also 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 sinusoidal 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 sinusoidal modulation signal.

[0067] Specifically, the controller 11 may be a processor with a data processing function, such as an MCU, a CPU, and a single-chip microcomputer, etc., which is not specifically limited in the embodiment of the present invention. The target amplitude signal A0, the target frequency signal F0, the target period signal T0, and the target duty cycle signal D0 may be obtained through the controller 11. Then, in the adjustment control circuit 10, the amplitude control signal output to the voltage-controlled DC power supply circuit 20 may 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 may be a corresponding analog signal, at which time the controller 11 may convert the target amplitude signal A0 into a digital signal through a D / A conversion interface, and then output the corresponding amplitude control signal to the voltage-controlled DC power supply circuit 20. When generating a drive control signal, the frequency modulation signal may be first output to the digital frequency synthesis module 12 through the controller 11, and the frequency modulation signal may be adjusted according to the target frequency signal F0, so that the digital frequency synthesis module 12 adjusts the frequency of the sinusoidal modulation signal according to the frequency modulation signal. At the same time, the controller 11 outputs a 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. When the drive output module 13 outputs a drive control signal to the inverter output circuit 30, the drive output module 13 can adjust the frequency, period and duty cycle of the drive control signal according to the PWM modulation signal and the sinusoidal modulation signal.

[0068] For example, Figure 31 is a signal schematic diagram provided by an embodiment of the present invention, in which S1 is a PWM modulation signal output by the controller 11 to the drive output module 13, S2 is a sinusoidal 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. Figure 3 As shown, the period of the PWM modulation signal S1 is T1, the duty cycle is T2 / T1, the period of the sinusoidal modulation signal S2 is T3, and the frequency is 1 / T3. In 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 sinusoidal modulation signal S2, and the frequency of the drive control signal is the same as the frequency of the sinusoidal modulation signal S2. In the T4 stage when the PWM modulation signal S1 outputs a high level, even if the sinusoidal modulation signal S2 outputs a waveform normally, the drive control signal does not output a valid pulse, that is, the duty cycle and period of the drive control signal are the same as 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 the PWM modulation signal S1, and the frequency of the ultrasonic drive signal S4 in the T2 stage is the same as the sinusoidal 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, thereby realizing the amplitude adjustment of the ultrasonic drive signal S4 output by the inverter output circuit 30; and the frequency of the sinusoidal modulation signal S2 output by the digital frequency synthesis module 12 can be adjusted by the controller 11, so that the frequency of the drive control signal S3 output by the drive output module 13 can be adjusted, thereby realizing the frequency adjustment of the ultrasonic drive signal S4 output by the inverter output circuit 30; and the period and duty cycle of the PWM modulation signal S1 can be adjusted by the controller 11, so that the period and duty cycle of the drive control signal S3 output by the drive output module 13 can be adjusted, thereby realizing the period and duty cycle of the ultrasonic drive signal S4 output by the inverter output circuit 30. It is possible to realize multi-parameter adjustment of the ultrasonic drive signal S4, thereby realizing multi-parameter adjustment of the ultrasonic energy, making the adjustment of the ultrasonic energy more refined, which is conducive to more accurate control of the power of the ultrasonic energy and is conducive to 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.

The obtained signal parameters can be used to monitor the working state and working time of the ultrasonic transducer 02, so as to control the ultrasonic energy regulating device to stop working when the ultrasonic transducer 02 has a fault such as aging. Among them, when the PWM modulation signal remains at a low level for a long time, the driving output module 13 stops outputting the valid pulse of the driving control signal, and can also send a reset signal to the synchronous sampling trigger module 14 to reset the synchronous sampling trigger module 14, so that the step signal output by the synchronous sampling trigger module 14 is a low level, so that the controller 11 stops acquiring the signal parameters of the ultrasonic driving signal.

The signal parameters may include the amplitude and 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 the amplitude and the effective value are both within the safety threshold range, a corresponding protection control signal can be output to the inverter output circuit 30 so that the inverter output circuit 30 continues to 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.

[0078] Optional, continue to refer to Figure 8 The inverter output circuit 30 also includes: a driving module 32 and a resonant filtering module 33; the driving module 32 is electrically connected to the regulating control circuit 10 and the inverter module 31 respectively; the driving module 32 is used to obtain the driving control signal output by the regulating control circuit 10, and amplify the driving control signal and output it to the inverter module 31; the resonant filtering module 33 is electrically connected to the inverter module 31 and the ultrasonic transducer 02 respectively; the resonant filtering module 33 is used to output an ultrasonic driving 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 signal (i.e., the first driving control signal and the second driving control signal) provided by the regulating control circuit 10, so that the amplified driving control signal can meet the control requirements of the transistors in the inverter module 31, so as to ensure that each transistor can be controlled to be turned on or off. Among them, the initial AC signal output by the inverter module 31 after inverting the DC voltage signal is a square wave AC signal, so 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 be turned on and off according to the frequency, period and duty cycle of the driving control signal (i.e., the first driving control signal and the second driving control signal), and the frequency, period and duty cycle of the square wave AC signal can be adjusted accordingly, so that the frequency, period and duty cycle of the square wave AC signal are related to the driving control signal. The resonant filter module 33 can filter the initial AC signal output by the inverter module 31, retaining the fundamental component, i.e., the sine component, so that the ultrasonic driving signal output to the ultrasonic transducer 02 can be a sine AC signal.

[0081] Based on the same inventive concept, an embodiment of the present invention further provides an ultrasonic energy regulation method, which can be executed by an ultrasonic energy regulation device provided by any embodiment of the present invention. Fig. 9 is a flow chart of a method for adjusting an ultrasonic drive signal provided by an embodiment of the present invention, such as Fig. 9 As shown, the method for adjusting the ultrasonic drive signal includes:

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, so that the amplitude of the DC voltage signal can be adjusted according to the amplitude control signal through the voltage-controlled DC power supply circuit 20, so that when the inverter output circuit 30 inverts the DC voltage signal to output the ultrasonic drive signal, the amplitude of the ultrasonic drive signal can be adjusted accordingly, thereby realizing the adjustment of the instantaneous electrical power of the ultrasonic drive signal, and then 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, and the amplitude of the ultrasonic drive signal increases, so that the instantaneous electric power increases, 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. Alternatively, when the 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, and the amplitude of the ultrasonic drive signal decreases, so that the instantaneous electric power decreases, and the instantaneous ultrasonic power of the ultrasonic energy can be reduced, which can solve the problem that the ultrasonic power is too high and the tissue damage is excessive.

[0087] At the same time, the target frequency signal F0, the target period signal T0 and the target duty cycle signal D0 of the regulating control circuit 10 regulate the frequency, period and duty cycle of the driving control signal. Then, when the inverter output circuit 30 inverts the DC voltage signal provided by the voltage-controlled DC power supply circuit 20 to output the ultrasonic driving signal, the ultrasonic driving signal frequency, period and duty cycle can be controlled according to the driving control signal. Among them, by setting the ultrasonic driving signal with a duty cycle, the ultrasonic transducer 02 can intermittently output high-power ultrasonic energy, and by adjusting the duty cycle of the ultrasonic driving signal, the intermittent time of outputting ultrasonic energy can be adjusted, which solves the problem of limited high-power output of the ultrasonic transducer 02 and the temperature rise of the target tissue, and can form sufficient damage to the target tissue while ensuring that the temperature of the ultrasonic transducer 02 is 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 driving signal, the output dose of the ultrasonic energy can be adjusted, so that the damage range to the target tissue can be effectively controlled. In addition, by adjusting the frequency of the sinusoidal signal, the frequency of the ultrasonic energy can be matched with the optimal operating frequency of the ultrasonic transducer 02, thereby ensuring that the ultrasonic transducer 02 has good operating performance.

The comprehensive regulation of multiple parameters of the ultrasonic driving signal output by the control device realizes the instantaneous ultrasonic power regulation of the ultrasonic energy, which can solve the problem that the instantaneous ultrasonic power is insufficient and cannot form effective tissue damage, and can solve the problem that the instantaneous ultrasonic power is too high and causes excessive tissue damage. It can also effectively control the working temperature of the ultrasonic transducer so as not to cause high-temperature damage to the target tissue, can adjust the output dose of the ultrasonic energy to effectively control the damage range to the target tissue, and can ensure that the ultrasonic transducer has good working performance, thus realizing multi-dimensional refined control of the ultrasonic energy, and realizing refined tissue ablation effect through the mutual assistance and mutual restriction of multiple parameters.

[0097] The embodiment of the present invention provides a method for adjusting a drive control signal. First, when generating a sinusoidal modulation signal, the sinusoidal modulation signal is controlled according to a target frequency signal to adjust the frequency of the sinusoidal modulation 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 a drive control signal, the frequency of the drive control signal can be adjusted according to the frequency of the sinusoidal modulation signal, and the period and duty cycle of the drive control signal can be adjusted according to the period and duty cycle of the PWM modulation signal, thereby 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. This can realize 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 refined control of the ultrasonic transducer is realized, and a refined tissue ablation effect is realized.
