Description

Technical Field

[0001] This application relates to the field of ultrasound therapy equipment technology, and more particularly to ultrasound drive devices and ultrasound therapy equipment. Background Technology

[0002] Currently, tissue ablation using high-intensity ultrasound energy has become an ideal minimally invasive treatment method and has gained widespread acceptance. Most therapeutic high-intensity ultrasound energy sources employ sinusoidal wave-driven ultrasound transducers.

As a result, the output power of different ultrasound transducers varies greatly when used on different patients, leading to inaccurate treatment dosage and significant individual differences in treatment effects. These differences are often difficult to detect during surgery. Summary of the Invention

[0100] Figure 1 This is a schematic diagram of the structure of an ultrasonic driving device provided for at least one embodiment of this application. Figure 1 As shown, the ultrasonic driving device 01 includes a driving control module 100 and a power detection module 200; the power detection module 200 is electrically connected to the driving control module 100; the driving control module 100 is used to acquire control information Sc and output an ultrasonic driving signal S0 according to the control information Sc, the ultrasonic driving signal S0 is used to drive the ultrasonic device 02 to work; the power detection module 200 is used to acquire voltage detection signal and current detection signal, and generate a power detection signal Q0 according to the voltage detection signal and current detection signal, so as to output to the driving control module 100; the voltage detection signal is a signal obtained by voltage sampling of the ultrasonic driving signal S0, and the current detection signal is a signal obtained by current sampling of the ultrasonic driving signal S0; the driving control module 100 is also used to adjust the amplitude of the ultrasonic driving signal S0 according to the power detection signal Q0.

The output end of the power detection module 200 is electrically connected with the power detection end of the drive control module 100, so that the power detection module 200 can output the power detection signal Q0 to the drive control module 100, and then the drive control module 100 can determine the actual output power according to the power detection signal Q0, so as to compare the actual output power with the target power, and control the amplitude of the ultrasonic drive signal S0 to increase when the actual output power is lower than the target power, so as to increase the actual output power of the ultrasonic drive device 01, and control the amplitude of the ultrasonic drive signal S0 to decrease when the actual output power is higher than the target power, so as to decrease the actual output power of the ultrasonic drive device 01, so as to realize the closed-loop adjustment of the output power. By adjusting the actual output power of the ultrasonic drive device 01 to be consistent with the target power, the output power of the ultrasonic device 02 can be more consistent when used on different patient individuals, so as to improve the treatment effect when treating different patients.

[0105] Optionally, the actual output power detected by the power detection module 200 is the active power output by the ultrasonic drive device 01. The target power is determined according to the control information, so that the target power can be determined according to at least one of the target amplitude, the target frequency, the target period and the target duty cycle in the control information.

[0106] The ultrasonic driving device provided by the embodiments of the present application obtains the control information through the driving control module, generates the ultrasonic driving signal for driving the ultrasonic equipment to work according to the control information, obtains the voltage detection signal and the current detection signal generated by sampling the ultrasonic driving signal through the power detection module, so that the power detection module can generate the power detection signal according to the voltage detection signal and the current detection signal, and the actual power output by the ultrasonic driving device can be detected, the power detection module is electrically connected with the driving control module, so that the power detection signal obtained by the power detection module can be provided to the driving control module, the driving control module can adjust the ultrasonic driving signal according to the power detection signal, the closed-loop adjustment of the output power of the ultrasonic driving device is realized, the actual output power of the ultrasonic driving device is consistent with the target power, the output power of the ultrasonic equipment when used on different patient individuals is consistent, and thus the treatment effect when treating different patients can be improved.

[0107] Optionally, Figure 2 is another structural schematic diagram of an ultrasonic driving device provided by some embodiments of the present application. As shown in Figure 2 The power detection module 200 includes a signal processing unit 210, a four-quadrant multiplier 220 and a power detection output unit 230; the input end of the signal processing unit 210 is electrically connected with the output end of the driving control module 100, the output end of the signal processing unit 210 is electrically connected with the input end of the four-quadrant multiplier 220; the output end of the four-quadrant multiplier 220 is electrically connected with the input end of the power detection output unit 230; the output end of the power detection output unit 230 is electrically connected with the power detection end of the driving control module 100; the signal processing unit 210 is used for obtaining the voltage detection signal and the current detection signal, and outputs the voltage adjustment signal U1 according to the voltage detection signal and the current adjustment signal I1 according to the current detection signal; the four-quadrant multiplier 220 is used for outputting the real-time power reference signal according to the voltage adjustment signal U1 and the current adjustment signal I1; the power detection output unit 230 is used for outputting the power detection signal Q0 to the driving control module 100 according to the real-time power reference signal.

[0108] During the process of presetting amplification ratio of the signal by the amplifier, the phase deviation between the signal before amplification and the signal after amplification and the problem of the actual amplification ratio not meeting the preset amplification ratio may occur due to the amplifier itself. The voltage detection signal can be a signal obtained by voltage sampling the ultrasonic drive signal S0 and then amplifying the signal by a preset ratio, and the current detection signal can be a signal obtained by current sampling the ultrasonic drive signal S0 and then amplifying the signal by a preset ratio. Therefore, the problems of the phase deviation between the voltage detection signal and / or the current detection signal and the ultrasonic drive signal S0 and the amplification ratio not meeting the preset ratio may occur. The signal processing unit 210 is adopted to adjust the amplitude and phase of the voltage detection signal and adjust the amplitude and phase of the current detection signal, so that the phase of the voltage adjustment signal U1 output after processing the voltage detection signal is the same as the phase of the signal obtained by voltage sampling the ultrasonic drive signal S0, the amplification ratio meets the preset ratio, and the phase of the current adjustment signal I1 output after processing the current detection signal is the same as the phase of the signal obtained by current sampling the ultrasonic drive signal S0, and the amplification ratio meets the preset ratio.

[0109] Based on the characteristics that the four-quadrant multiplier 220 can directly process the alternating current signal, the four-quadrant multiplier 220 is adopted to multiply the voltage adjustment signal U1 and the current adjustment signal I1 to obtain the real-time power reference signal, which can simplify the signal processing process. The power detection output unit 230 generates the power detection signal Q0 after filtering and / or amplifying the real-time power reference signal. The amplification processing is helpful to make the amplitude of the power detection signal Q0 meet the sampling range when the driving control module 100 samples the power detection signal Q0 provided to the driving control module 100.

The current signal processing circuit 212 can adjust the amplitude and phase of the current detection signal to obtain the current adjusted signal I1, so that the amplitude of the current adjusted signal I1 is the amplitude of the ultrasonic drive signal S0 after current sampling and preset multiple amplification, and the phase of the current adjusted signal I1 is the same as the phase of the signal obtained by current sampling on the ultrasonic drive signal S0. This can be beneficial to improve the accuracy of the obtained real-time power reference signal, and further improve the accuracy of the power detection signal Q0.

[0112] Optionally, the reference Figure 3 The power detection output unit 230 comprises: a low-pass filter circuit 231; the low-pass filter circuit 231 is electrically connected between the output end of the four-quadrant multiplier 220 and the power detection end of the drive control module 100; the low-pass filter circuit 231 is used for filtering the real-time power reference signal to obtain the power detection signal Q0, and outputting to the drive control module 100.

[0113] Specifically, as known from the above embodiment, the voltage adjusted signal U1 is an alternating current signal obtained by voltage sampling and processing on the ultrasonic drive signal S0, and the current adjusted signal I1 is an alternating current signal obtained by current sampling and processing on the ultrasonic drive signal S0, so that the real-time power reference signal outputted by multiplying the voltage adjusted signal U1 and the current adjusted signal I1 through the four-quadrant multiplier 220 is also an alternating current signal. The low-pass filter circuit 231 can perform average value filtering on the alternating current real-time power reference signal, so that the outputted power detection signal Q0 is a direct current voltage signal.

[0114] Optionally, Figure 4 is a structural schematic diagram of still another ultrasonic driving device provided by some embodiments of the present application. As shown in Figure 4 The power detection output unit 230 further includes a gain adjustment circuit 232, which is electrically connected between the low-pass filter circuit 231 and the power detection end of the driving control module 100. The gain adjustment circuit 232 is configured to adjust the amplitude of the power detection signal Q0 and output the power detection signal Q0 with the adjusted amplitude to the driving control module 100.

[0115] Specifically, the amplitude of the real-time power reference signal output by the four-quadrant multiplier 220 is small, which results in a small amplitude of the power detection signal Q0 output by the low-pass filter circuit 231. If the power detection signal Q0 with the small amplitude is directly output to the driving control module 100, the driving control module 100 will be difficult to distinguish, which is not conducive to the adjustment of the ultrasonic driving signal S0. The gain adjustment circuit 232 is configured to amplify the power detection signal Q0 output by the low-pass filter circuit 231, so that the amplitude of the power detection signal Q0 is amplified to the full scale of AD sampling in the driving control module 100. As a result, the driving control module 100 can accurately identify the size of the power detection signal Q0, which is conducive to the accurate adjustment of the ultrasonic driving signal S0.

[0116] Optionally, Figure 5 is a structural schematic diagram of still another ultrasonic driving device provided by some embodiments of the present application. As shown in Figure 5 The power detection module 200 further includes a zero adjustment unit 240, which is electrically connected to the four-quadrant multiplier 220. The zero adjustment unit 240 is configured to output a voltage zero adjustment signal to the four-quadrant multiplier 220. The four-quadrant multiplier 220 is further configured to obtain the product of the voltage adjustment signal and the current adjustment signal, and generate a real-time power reference signal according to the product and the zero adjustment signal.

[0117] The driving control module 100 in the state of stopping working may output a small amplitude ultrasonic driving signal S0 due to disturbance or accidental touch of the operator, which is manifested as a small amplitude voltage fluctuation or current fluctuation. At this time, the ultrasonic driving signal S0 should be kept at zero to avoid the ultrasonic device 02 from being mistakenly started. The zeroing unit 240 can provide a zeroing signal to the four-quadrant multiplier 220. After the four-quadrant multiplier 220 multiplies the voltage adjustment signal U1 and the current adjustment signal I1 to obtain a product, the four-quadrant multiplier 220 can compare the product with a preset value. If the product is less than the preset value, it indicates that the small amplitude signal is generated due to disturbance or accidental touch of the operator. At this time, the product is subtracted from the zeroing signal to output a real-time power reference signal equal to zero, so that the power detection signal Q0 is kept at zero, thereby keeping the ultrasonic driving signal S0 output by the driving control module 100 at zero. It can be understood that in the case where the zeroing signal is greater than or equal to the product of the voltage adjustment signal U1 and the current adjustment signal I1, the value output after the product is subtracted from the zeroing signal is always zero. If the product is greater than or equal to the preset value, it indicates that the driving control module 100 is in a normal working state. At this time, the real-time power reference signal generated by subtracting the product of the voltage adjustment signal U1 and the current adjustment signal I1 from the zeroing signal still has a large amplitude, which can be output by the four-quadrant multiplier 220 to the driving control module 100 for corresponding closed-loop control.

[0118] Optionally, the size of the zeroing signal can be set according to design requirements. For example, the zeroing signal can be equal to the preset value, and the preset value can be set according to the normal accidental touch of the operator and the disturbance.

[0119] The above embodiments introduce the specific settings and working principles of the power detection module, which can realize real-time detection of the output power of the driving control module, so as to realize closed-loop control of the output power of the driving control module. The specific settings and working principles of the driving control module are described in detail below.

[0120] Optionally, Figure 6 is a structural schematic diagram of another ultrasonic driving device provided by some embodiments of the present application. As shown in Figure 6As shown, the drive control module 100 comprises: a regulation control submodule 110, a voltage-controlled direct current power supply submodule 120, and a drive output submodule 130; a control input end of the regulation control submodule 110 receives control information Sc, a power detection end of the regulation control submodule 110 is electrically connected with an output end of the power detection module 200, a drive output end of the regulation control submodule 110 is electrically connected with a control end of the drive output submodule 130, and a voltage regulation output end of the regulation control submodule 110 is electrically connected with a voltage regulation input end of the voltage-controlled direct current power supply submodule 120; a power supply input end of the voltage-controlled direct current power supply submodule 120 receives a first direct current voltage signal VCC1, an output end of the voltage-controlled direct current power supply submodule 120 is electrically connected with an input end of the drive output submodule 130, and an output end of the drive output submodule 130 is electrically connected with the ultrasonic device 02.

[0121] The regulation control submodule 110 is configured to output a voltage regulation control signal to the voltage-controlled direct current power supply submodule 120 according to the control information Sc and the power detection signal Q0; the regulation control submodule 110 is further configured to output a drive control signal to the drive output submodule 130 according to the control information Sc; the voltage-controlled direct current power supply submodule 120 is configured to output a second direct current voltage signal to the drive output submodule 130 according to the voltage regulation control signal and the first direct current voltage signal VCC1; and the drive output submodule 130 is configured to output an ultrasonic drive signal S0 to the ultrasonic device 02 according to the second direct current voltage signal and the drive control signal.

[0122] In an available embodiment, the regulation control submodule 110 can generate the voltage regulation control signal according to a target amplitude in the control information Sc and the power detection signal. The voltage regulation control signal is a voltage signal, and the voltage-controlled direct current power supply submodule 120 can amplify or reduce the voltage regulation control signal in a proportional manner to output a corresponding second direct current voltage signal, or the voltage-controlled direct current power supply submodule 120 can amplify or reduce the first direct current voltage signal VCC1 according to the voltage regulation control signal, so that the amplitude of the second direct current voltage signal output by the voltage-controlled direct current power supply submodule 120 can be adjusted by adjusting the voltage value of the voltage regulation control signal. The voltage-controlled direct current power supply submodule 120 can comprise a BUCK circuit and a BOOST circuit to realize the functions of voltage boosting and voltage reducing, respectively.

[0123] Optionally, the regulation control submodule 110 can adjust the voltage regulation control signal by adjusting the target amplitude, or can adjust the voltage regulation control signal according to the power detection signal.

[0124] The regulation control submodule 110 can also be electrically connected with the drive output submodule 130, configured to output a drive control signal to the drive output submodule 130, and adjust the frequency, period, and duty cycle of the drive control signal according to a target frequency, a target period, and a target duty cycle in the control information.

[0125] Exemplary, Figure 7 is a signal diagram provided by some embodiments of the present application. As shown, assuming that the period of the driving control signal S3 is T1, the stage in which the driving control signal S3 outputs a valid pulse within the period T1 is T2, then the duty cycle D1 = T2 / T1, and the frequency F1 of the driving control signal S3 is the frequency of the driving control signal S3 outputting a valid pulse within the stage T2. Within the stage T2 in which the driving control signal S3 outputs a valid pulse, the driving control signal S3 can present valid and invalid levels alternately, and the driving control signal S3 remains invalid within other stages of the period T1. Figure 7

[0126] The driving output submodule 130 inverts the second DC voltage signal provided by the voltage-controlled DC power supply submodule 120 according to the driving control signal S3 to output an ultrasonic driving signal S0 to the ultrasonic device 02. In this way, the driving output submodule 130 can control the amplitude of the ultrasonic driving signal S0 according to the amplitude of the second DC voltage signal, and the amplitude of the ultrasonic driving signal S0 is related to the instantaneous electric power of the ultrasonic device 02, thereby facilitating the adjustment of the instantaneous ultrasonic power of the ultrasonic energy output by the ultrasonic device 02.

[0127] When the instantaneous ultrasonic power is insufficient, the adjustment control submodule 110 can increase the adjustment voltage control signal according to the power detection signal Q0, or can adjust the target amplitude to increase the adjustment voltage control signal, so that the second DC voltage signal output by the voltage-controlled DC power supply submodule 120 increases, and the amplitude of the ultrasonic driving signal S0 increases, so that the instantaneous electric power increases, and the increase in the instantaneous electric power increases the instantaneous acoustic power output by the ultrasonic device 02, thereby increasing the amplitude of the ultrasonic energy to increase the instantaneous ultrasonic power, which is beneficial to avoid the problem that the insufficient instantaneous ultrasonic power cannot form effective tissue damage. Alternatively, when the instantaneous ultrasonic power is too high, the adjustment control submodule 110 can decrease the adjustment voltage control signal according to the power detection signal Q0, or can adjust the target amplitude to decrease the voltage control signal, so that the second DC voltage signal output by the voltage-controlled DC power supply submodule 120 decreases, and the amplitude of the ultrasonic driving signal S0 decreases, so that the instantaneous electric power decreases, thereby decreasing the amplitude of the ultrasonic energy to decrease the instantaneous ultrasonic power, which is beneficial to solve the problem that the excessive instantaneous ultrasonic power causes excessive tissue damage.

[0128] ​Since the driving output submodule 130 can control the frequency, period and duty cycle of the ultrasonic driving signal S0 according to the frequency, period and duty cycle of the driving control signal, the electric power of the ultrasonic driving signal S0 can also be adjusted, so that when the ultrasonic device 02 outputs ultrasonic energy, the power of the ultrasonic energy can be adjusted according to the frequency, period and duty cycle of the ultrasonic energy corresponding to the frequency, period and duty cycle of the ultrasonic driving signal S0. By setting the ultrasonic driving signal S0 to have a duty cycle, the ultrasonic energy can have a certain duty cycle, so that the ultrasonic device 02 can intermittently output high-power ultrasonic energy, and by adjusting the duty cycle of the ultrasonic driving signal S0, the intermittent time of the output ultrasonic energy can be adjusted, solving the problems of limited high-power output and too fast temperature rise of the ultrasonic device 02. In addition, by adjusting the period of the ultrasonic driving signal S0, the period 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 periods of the output ultrasonic energy within a preset time, for example, 3 periods of ultrasonic energy or 10 periods of ultrasonic energy within 1s. In this way, 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 ultrasonic driving signal S0, the frequency of the ultrasonic energy can be matched with the optimal working frequency of the ultrasonic device 02, which can help to ensure good working performance of the ultrasonic device 02.

[0129] Optionally, Figure 8 is another structure schematic diagram of an ultrasonic driving device provided by some embodiments of the present application. As shown in Figure 8 The voltage-controlled direct current power supply submodule 120 includes: a voltage-controlled signal processing circuit 121, a pulse width control signal generation circuit 122 and a voltage conversion circuit 123; the voltage-controlled signal processing circuit 121 is electrically connected with the adjustment control submodule 110 at the voltage adjustment input end, and the output end of the voltage-controlled signal processing circuit 121 is electrically connected with the first input end of the pulse width control signal generation circuit 122; the second input end of the pulse width control signal generation circuit 122 is electrically connected with the output end of the voltage conversion circuit 123, and the output end of the pulse width control signal generation circuit 122 is electrically connected with the control end of the voltage conversion circuit 123; the power supply input end of the voltage conversion circuit 123 receives the first direct current voltage signal VCC1, and the output end of the voltage conversion circuit 123 is electrically connected with the input end of the driving output submodule 130; the voltage-controlled signal processing circuit 121 is used for receiving the voltage adjustment control signal and generating a voltage adjustment control processing signal according to the voltage adjustment control signal; the pulse width control signal generation circuit 122 is used for receiving the second direct current voltage and the voltage adjustment control processing signal and generating a pulse width control signal according to the second direct current voltage signal and the voltage adjustment control processing signal; and the voltage conversion circuit 123 is used for receiving the first direct current voltage signal VCC1 and the pulse width control signal and outputting a second direct current voltage signal according to the first direct current voltage signal and the pulse width control signal.

[0130] Specifically, the voltage control signal processing circuit 121 can amplify or reduce the voltage control signal, so that the voltage control processing signal is the amplified or reduced voltage control signal. The pulse width control signal generation circuit 122 receives the voltage control signal on the one hand, so that the second DC voltage signal output by the voltage control DC power supply sub-module 120 tends to be consistent with the target amplitude, and on the other hand, also receives the second DC voltage signal output by the voltage conversion circuit 123, so that feedback adjustment of the second DC voltage signal can be realized, so that the second DC voltage signal output by the voltage control DC power supply sub-module 120 is dynamically adjusted based on the target amplitude, and remains constant. The pulse width control signal generation circuit 122 outputs the pulse width control signal to the voltage conversion circuit 123, so that the voltage conversion circuit 123 adjusts the amplitude of the second DC voltage signal output according to the pulse width control signal and the first voltage signal VCC1.

[0131] Optionally, Figure 9 is a structural schematic diagram of an ultrasonic driving device provided by another embodiment of the present application, as Figure 9 The voltage control signal processing circuit 121 includes: a reference signal output unit 1211 and a voltage control adjustment unit 1212; the first input end of the voltage control adjustment unit 1212 is electrically connected with the reference signal output unit 1211, the second input end of the voltage control adjustment unit 1212 is electrically connected with the adjustment control sub-module 110, and the output end of the voltage control adjustment unit 1212 is electrically connected with the input end of the pulse width control signal generation circuit 122; the reference signal output unit 1211 is configured to generate a voltage control reference signal according to a preset voltage; the voltage control adjustment unit 1212 is configured to receive the voltage control signal and the voltage control reference signal, and generate a voltage control processing signal according to the voltage control signal and the voltage control reference signal; the voltage control processing signal and the voltage control signal are symmetrical about the voltage control reference signal.

[0132] In a possible implementation, the reference signal output unit 1211 generates the voltage control reference signal according to a preset voltage, which is the reference voltage of the reference signal output unit 1211, and can be set based on demand, and can be 1V, 2V, 2.5V, 4V, etc., which is not limited herein.

[0133] Since the voltage control signal and the voltage control processing signal are symmetrical about the voltage reference signal, if the voltage reference signal is greater than the voltage control signal, the voltage control processing signal is the amplified voltage control signal; if the voltage reference signal is less than the voltage control signal, the voltage control processing signal is the reduced voltage control signal, and if the voltage reference signal is equal to the voltage control signal, the voltage control signal is equal to the voltage control processing signal, that is, the reference signal output unit 1211 can perform mirror processing on the voltage control signal based on the voltage reference signal. In order to realize the amplification function of the voltage control signal, the voltage reference signal is usually greater than the voltage control signal, so the appropriate voltage reference signal can be selected based on the range of the voltage control signal.

[0134] In the process of adjusting the amplitude of the voltage control signal, since the voltage control signal and the voltage control processing signal are symmetrical about the voltage reference signal, if the amplitude of the voltage control signal is increased, the amplitude of the voltage control processing signal is reduced, and if the amplitude of the voltage control signal is reduced, the amplitude of the voltage control processing signal is increased.

[0135] For example, if the voltage reference signal is 2.5V and the voltage control signal is 1V, the voltage control processing is 2.5V+(2.5V-1V)=4V, that is, the voltage control processing and the voltage control signal are symmetrical about the voltage reference signal.

[0136] Optionally, with reference to Figure 9 The pulse width control signal generation circuit 122 includes a feedback sampling unit 1221 and a power management unit 1222; the first input end of the feedback sampling unit 1221 is electrically connected with the output end of the voltage control signal processing circuit 121, the second input end of the feedback sampling unit 1221 is electrically connected with the output end of the voltage conversion circuit 123, and the output end of the feedback sampling unit 1221 is electrically connected with the input end of the power management unit 1222; the output end of the power management unit 1222 is electrically connected with the control end of the voltage conversion circuit 123; the feedback sampling unit 1221 is used for generating a feedback control signal according to the second direct current voltage signal and the voltage control processing signal; and the power management unit 1222 is used for generating a pulse width control signal according to the feedback control signal.

[0137] Specifically, in the case that the voltage control signal remains unchanged, the voltage control processing signal output by the voltage control signal processing circuit 121 remains unchanged, the feedback sampling unit 1221 receives the voltage control signal and the second direct current voltage signal output by the voltage conversion circuit 123, processes the voltage control signal and the second direct current voltage signal to generate a feedback control signal, and outputs the feedback control signal to the power management unit 1222.

[0138] In a possible implementation manner, Figure 10 is a structural schematic diagram of another ultrasonic driving device provided by some embodiments of the present application. As shown in FIG.Figure 10 As shown, the feedback sampling unit 1221 includes a first resistor R1, a second resistor R2 and a third resistor R3, the first resistor R1 and the second resistor R2 are connected in series between the output terminal of the voltage conversion circuit 123 and the ground terminal GND, and the first resistor R1 and the second resistor R2 are electrically connected to the first node a1, the third resistor R3 is electrically connected between the output terminal of the voltage-controlled signal processing circuit 121 and the first node a1, and the first node a1 is electrically connected to the input terminal of the power management unit 1222 as the output node of the feedback sampling unit 1221. The relationship between the voltage control processing signal and the second DC voltage signal is: (the voltage of the second DC voltage signal - the voltage of the first node a1) / R1 + (the voltage of the voltage control processing signal - the voltage of the first node a1) / R3 = the voltage of the first node a1 / R2. In the steady state, the voltage of the first node a1 always maintains equal to the internal reference voltage of the power management unit 1222; in the transient state, if the voltage control processing signal changes, the second DC voltage signal will change synchronously to maintain the above equation.

[0139] In a possible implementation, the power management unit 1222 can be provided with an error amplifier, a slope generation circuit and a comparator, and the difference between the internal reference voltage and the received feedback control signal can be integrated and amplified by the error amplifier, and the error signal output by the amplifier is compared with the slope voltage signal output by the slope generation circuit to obtain a corresponding square wave signal, i.e. a pulse width control signal. That is, the power management unit 1222 can adjust the pulse width of the output pulse width control signal according to the input feedback control signal, so that the voltage conversion circuit 123 can convert the first DC voltage signal according to the pulse width control signal to realize the amplitude adjustment of the second DC voltage signal.

[0140] Based on the above implementation, in the case of needing to reduce the amplitude of the second DC voltage signal, the amplitude of the voltage regulation control signal needs to be reduced first, and the voltage regulation control signal is symmetrical to the voltage regulation control processing signal with respect to the voltage regulation reference signal, so that the voltage regulation control processing signal increases, that is, the voltage of the first node a1 increases. Since the reference voltage in the power management unit 1222 does not change, in order to make the difference between the reference voltage and the feedback control signal zero, the power management unit 1222 controls the pulse width of the pulse width control signal output to decrease, thereby controlling the amplitude of the second DC voltage signal output by the voltage conversion circuit 123 to decrease, so that the voltage of the first node a1 remains equal to the reference voltage. Based on the same principle, in the case of needing to control the second DC voltage signal to increase, the amplitude of the voltage regulation control signal needs to be increased first, and the voltage regulation control signal is symmetrical to the voltage regulation control processing signal with respect to the voltage regulation reference signal, so that the voltage regulation control processing signal decreases, that is, the voltage of the first node a1 decreases. Since the reference voltage in the power management unit 1222 does not change, in order to make the difference between the reference voltage and the feedback control signal zero, the power management unit 1222 generates the pulse width of the pulse width control signal to increase, thereby controlling the amplitude of the second DC voltage signal output by the voltage conversion circuit 123 to increase, so that the voltage of the first node a1 remains equal to the reference voltage.

[0141] Since the amplitude of the second DC voltage signal is proportional to the amplitude of the voltage regulation control signal, in the case of the voltage regulation control signal being zero, the second DC voltage signal output can be guaranteed to be zero, which is beneficial to avoid safety hazards.

[0142] Optionally, continuing to refer to Figure 9 Or Figure 10 The voltage conversion circuit 123 comprises a power conversion unit 1231 and a low-pass filter unit 1232; the control end of the power conversion unit 1231 is electrically connected with the output end of the pulse width control signal generation circuit 122, and the output end of the power conversion unit 1231 is electrically connected with the input end of the low-pass filter unit 1232; the output end of the low-pass filter unit 1232 is electrically connected with the input end of the driving output sub-module 130; the power input end of the power conversion unit 1231 receives the first DC voltage signal VCC1; the power conversion unit 1231 is configured to generate a square wave voltage signal according to the first DC voltage signal VCC1 and the pulse width control signal; and the low-pass filter unit 1232 is configured to output the second DC voltage signal according to the square wave voltage signal.

[0143] Specifically, the power conversion unit 1231 converts the first direct current voltage signal VCC1 into a square wave voltage signal according to the pulse width control signal, and the pulse width of the square wave voltage signal is equal to the pulse width of the pulse width control signal. The square wave voltage signal is low-pass filtered by the low-pass filter unit 1232 and outputs a direct current voltage signal (i.e., a second direct current voltage signal), and the amplitude of the second direct current voltage signal is related to the duty cycle of the square wave voltage signal. Therefore, the amplitude of the second direct current voltage signal is related to the pulse width control signal, so that the amplitude of the second direct current voltage signal can be controlled by adjusting the pulse width of the pulse width control signal, and the amplitude of the second direct current voltage signal is consistent with the amplitude of the voltage regulation control signal.

[0144] For example, the low-pass filter unit 1232 is an LC filter circuit.

[0145] Optionally, Figure 11 is a structural schematic diagram of another ultrasonic driving device provided by some embodiments of the present application. As shown in Figure 11 The adjustment control sub-module 110 includes a waveform control circuit 111 and a given adjustment circuit 112. The control input end of the waveform control circuit 111 obtains control information Sc, the given output end of the waveform control circuit 111 is electrically connected with the given input end of the given adjustment circuit 112, and the driving output end of the waveform control circuit 111 is electrically connected with the control end of the driving output sub-module 130. The power detection end of the given adjustment circuit 112 is electrically connected with the output end of the power detection module 200, and the output end of the given adjustment circuit 112 is electrically connected with the voltage regulation input end of the voltage-controlled direct current power supply sub-module 120. The control information Sc includes a target amplitude and a target frequency. The waveform control circuit 111 is configured to output a given control signal to the given adjustment circuit 112 according to the target amplitude. The waveform control circuit 112 is further configured to output a driving control signal to the driving output sub-module 130 according to the target frequency. The given adjustment circuit 112 is configured to output a voltage regulation control signal to the voltage-controlled direct current power supply sub-module 120 according to the given control signal and the power detection signal.

[0146] Specifically, the waveform control circuit 111 can output a corresponding given control signal to the given adjustment circuit 112 according to the target amplitude in the control information Sc, that is, the given control signal output by the waveform control circuit 111 corresponds to the target amplitude, so as to control the amplitude of the ultrasonic driving signal S0 to be the same as the target amplitude. After receiving the given control signal, the given adjustment circuit 112 generates a corresponding voltage regulation control signal and outputs it to the voltage-controlled direct current power supply sub-module 120, so that the voltage-controlled direct current power supply sub-module 120 generates a second direct current voltage signal by regulating the first direct current voltage signal VCC1 according to the voltage regulation control signal, so that the amplitude of the ultrasonic driving signal S0 output by the driving output sub-module 130 according to the second direct current voltage signal is the same as the target amplitude. At the same time, the given adjustment circuit 112 also acquires the power detection signal Q0, and after acquiring the power detection signal Q0, compares the power detection signal Q0 with the given control signal, and adjusts the output voltage regulation control signal according to the difference between the two, so that the actual power of the ultrasonic driving signal S0 is equal to the target power corresponding to the target amplitude. It can be understood that the power detection signal Q0 and the given control signal are both voltage signals, and when the difference between the power detection signal Q0 and the given control signal is greater than zero, it is determined that the actual power of the ultrasonic driving signal S0 exceeds the target power corresponding to the target amplitude, at which time the voltage regulation control signal can be adaptively reduced to reduce the actual power of the ultrasonic driving signal S0 to equal the target power corresponding to the target amplitude; when the difference between the power detection signal Q0 and the given control signal is less than zero, it is determined that the actual power of the ultrasonic driving signal S0 is less than the target power corresponding to the target amplitude, at which time the voltage regulation control signal can be adaptively increased to increase the actual power of the ultrasonic driving signal S0 to equal the target power corresponding to the target amplitude, so as to facilitate dynamic adjustment of the actual power of the ultrasonic driving signal S0, so as to help the ultrasonic driving signal S0 to drive the ultrasonic device 02 to achieve effective treatment effect.

[0147] The waveform control circuit 111 is also configured to generate a driving control signal according to the target frequency in the control information Sc, and when the control information further includes a target period and a target duty cycle, the waveform control circuit 111 is also configured to generate a driving signal according to the target frequency, the target period and the target duty cycle. The driving control signal is output to the driving output sub-module 130, so that the driving output sub-module 130 adjusts the frequency, period and duty cycle of the ultrasonic driving signal S0 according to the driving control signal.

[0148] Optionally, Figure 12 is a structural schematic diagram of an ultrasonic driving device provided by another embodiment of the present application. As Figure 12As shown, the waveform control circuit 111 comprises a control unit 1111, a sine signal generation unit 1112 and a pulse generation unit 1113; a control input end of the control unit 1111 receives the control information Sc, a given output end of the control unit 1111 is electrically connected with a given input end of the given regulating circuit 112, a frequency output end of the control unit 1111 is electrically connected with an input end of the sine signal generation unit 1112, an output end of the sine signal generation unit 1112 is electrically connected with an input end of the pulse generation unit 1113, and an output end of the pulse generation unit 1113 is electrically connected with a control end of the drive output sub-module 130; the control unit 1111 is configured to generate a given control signal according to the target amplitude and output to the given regulating circuit 112; the control unit 1111 is further configured to generate a frequency control signal according to the target frequency and output to the sine signal generation unit 1112; the sine signal generation unit 1112 is configured to generate a sine modulation signal according to the frequency control signal and output to the pulse generation unit 1113; and the pulse generation unit 1113 is configured to generate a drive control signal according to the sine modulation signal and a preset square wave signal and output to the drive output sub-module 130.

[0149] Optionally, the control unit 1111 can be a processor with data processing function, such as MCU, CPU and single-chip microcomputer, etc., and the present embodiment does not make specific limitation thereto. The control information Sc can be acquired by the control unit 1111, and a corresponding given control signal can be output to the given regulating circuit 112 according to the target amplitude in the control information Sc.

[0150] The control unit 1111 can also generate a frequency control signal according to the target frequency in the control information Sc, so that the sine signal generation unit 1112 generates a sine modulation signal according to the frequency control signal, the frequency of the sine modulation signal is equal to the target frequency, and the sine modulation signal is used to adjust the frequency of the drive control signal output by the pulse generation unit 1113.

[0151] For example, in combination with reference to Figure 7 and Figure 12 , the drive control signal S3 comprises a first drive control signal S31 and a second drive control signal S32. In the T2 stage, the pulse generation unit 1113 can control the first drive control signal S31 to output an effective pulse when the sine modulation signal S2 outputs a positive half-cycle sine wave, and control the second drive control signal S32 to output an effective pulse when the sine modulation signal S2 outputs a negative half-cycle sine wave, so that the phase difference between the first drive control signal S31 and the second drive control signal S32 is equal to 180°.

[0152] In a possible implementation, the control unit 1111 is further electrically connected with the pulse generating unit 1113, so that the control unit 1111 can output a preset square wave signal to the pulse generating unit 1113, so that the control unit 1111 can adjust the period and duty cycle of the preset square wave signal according to the target period and target duty cycle in the control information Sc. When the pulse generating unit 1113 outputs the drive control signal to the drive output submodule 130, the period and duty cycle of the drive control signal can be adjusted according to the preset square wave signal, so that the period and duty cycle of the ultrasonic drive signal S0 are the same as the period and duty cycle of the preset square wave signal respectively.

[0153] Specifically, referring to Figure 7, the period of the preset square wave 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 of the output high level of the preset square wave signal, the driving output submodule 130 can output a driving control signal S3 with a pulse according to the sinusoidal modulation signal S2, and the frequency of the driving control signal is the same as that of the sinusoidal modulation signal S2. In the T4 stage of the output low level of the preset square wave signal S1, even if the sinusoidal modulation signal S2 normally outputs a waveform, the driving control signal S3 always remains in a low level state, that is, the duty cycle and the period of the driving control signal S3 are the same as those of the preset square wave signal S1. Therefore, when the driving output submodule 130 outputs the ultrasonic driving signal S0 according to the driving control signal S3 and the second direct current voltage signal, the duty cycle and the period of the ultrasonic driving signal S0 are the same as those of the preset square wave signal S1, the frequency of the ultrasonic driving signal S0 in the T2 stage is the same as that of the sinusoidal modulation signal S2, and the amplitude of the ultrasonic driving signal S0 is related to the amplitude of the second direct current voltage signal. Therefore, the amplitude of the voltage-controlled direct current power supply submodule 120 can be adjusted by the control unit 1111 to adjust the amplitude of the second direct current voltage signal output by the voltage-controlled direct current power supply submodule 120, and then the amplitude of the ultrasonic driving signal S0 output by the driving output submodule 130 can be adjusted; the frequency of the sinusoidal modulation signal S2 output by the sinusoidal signal generation unit 1112 can be adjusted by the control unit 1111, the frequency of the driving control signal S3 output by the driving output submodule 130 can be adjusted, and then the frequency of the ultrasonic driving signal S0 output by the driving output submodule 130 can be adjusted; and the period and the duty cycle of the preset square wave signal S1 can be adjusted by the control unit 1111, the period and the duty cycle of the driving control signal S3 output by the pulse generation unit 1113 can be adjusted, and then the period and the duty cycle of the ultrasonic driving signal S0 output by the driving output submodule 130 can be adjusted. The multi-parameter adjustment of the ultrasonic driving signal S0 can be realized, the multi-parameter adjustment of the ultrasonic energy output by the ultrasonic device 02 can be realized, the adjustment of the ultrasonic energy is more refined, the power of the ultrasonic energy can be more accurately controlled, and the working performance of the ultrasonic device 02 can be improved.

[0154] In summary, the period of the adjusted ultrasonic driving signal S0 is the same as that of the preset square wave signal, which is T1, the stage of outputting the sinusoidal alternating signal waveform of the ultrasonic driving signal S0 in the period T1 is T2, the duty cycle D1 is T2 / T1, and the frequency F1 of the ultrasonic driving signal S0 is the frequency of outputting the sinusoidal alternating signal waveform in the T2 stage, that is, F1=1 / T3.

[0155] Optionally, referring to Figure 12The driving output submodule 130 comprises a high-frequency square wave inverter circuit 131 and a resonance circuit 132. The input end of the high-frequency square wave inverter circuit 131 is electrically connected with the output end of the voltage-controlled direct-current power supply submodule 120. The control end of the high-frequency square wave inverter circuit 131 is electrically connected with the driving output end of the adjustment and control submodule 110. The output end of the high-frequency square wave inverter circuit 131 is electrically connected with the input end of the resonance circuit 132. The output end of the resonance circuit 132 is electrically connected with the ultrasonic device 02. The high-frequency square wave inverter circuit 131 is used for outputting a high-frequency square wave voltage signal to the resonance circuit 132 according to the second direct-current voltage signal and the driving control signal. The resonance circuit 132 is used for converting the high-frequency square wave voltage signal into a sinusoidal alternating current signal, so as to output an ultrasonic driving signal S0 to the ultrasonic device 02.

[0156] Specifically, the high-frequency square wave inverter circuit 131 can invert the received second direct-current voltage signal into an alternating current high-frequency square wave voltage signal under the control of the driving control signal. The high-frequency square wave voltage signal is filtered by the resonance circuit 132, and the fundamental component, i.e., the sinusoidal component, is retained, so that the ultrasonic driving signal S0 output to the ultrasonic device 02 is a sinusoidal alternating current signal.

[0157] Exemplarily, Figure 13 is a structural schematic diagram of a high-frequency square wave inverter circuit provided by some embodiments of the present application, which is combined with reference to Figure 7 , Figure 12 and Figure 13 The high-frequency square wave inverter circuit 131 comprises 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 end "+" and the negative end "-" of the voltage-controlled direct-current power supply submodule 120. The third transistor M3 and the fourth transistor M4 are electrically connected in sequence between the positive end "+" and the negative end "-" of the voltage-controlled direct-current power supply submodule 120. The gate of the first transistor M1 and the gate of the fourth transistor M4 both receive a first driving control signal S31. The gate of the second transistor M2 and the gate of the third transistor M3 both receive a second driving control signal S32. The pulse generation unit 1113 is further used for adjusting the dead time of the first driving control signal S31 and the second driving 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 at different times, and control the third transistor M3 and the fourth transistor M4 to be turned on at different times.

[0158] Specifically, the high-frequency square wave inverter circuit 131 can be an H-bridge inverter circuit, wherein the drain electrodes of the first transistor M1 and the third transistor M3 are electrically connected to the positive terminal "+" of the voltage-controlled direct-current power supply submodule 120, the source electrode of the first transistor M1 and the drain electrode of the second transistor M2 are electrically connected to the second node a2, the source electrode of the third transistor M3 and the drain electrode of the fourth transistor M4 are electrically connected to the third node a3, and the source electrode of the second transistor M2 and the source electrode of the fourth transistor M4 are electrically connected to the negative terminal "-" of the voltage-controlled direct-current power supply submodule 120. The second node a2 and the third node a3 are output terminals of the high-frequency square wave inverter circuit 131. In this way, the first transistor M1 and the fourth transistor M4 are controlled to be synchronously turned on, the second transistor M2 and the third transistor M3 are controlled to be synchronously turned on, and the first transistor M1 and the second transistor M2 are controlled to be asynchronously turned on, so that the high-frequency square wave inverter circuit 131 inverts the second direct-current voltage signal provided by the voltage-controlled direct-current power supply submodule 120 and outputs a high-frequency square wave voltage signal corresponding to the amplitude of the second direct-current voltage signal. Therefore, by setting the gate electrodes of the first transistor M1 and the fourth transistor M4 to receive the first driving control signal S31 and setting the gate electrodes of the second transistor M2 and the third transistor M3 to receive the second driving control signal S32, the first transistor M1 and the fourth transistor M4 are synchronously turned on or turned off under the control of the same driving control signal, and the second transistor M2 and the third transistor M3 are synchronously turned on or turned off under the control of the same driving control signal, so as to realize the inverting output function. By setting the phase difference between the first driving control signal S31 and the second driving control signal S32 to be equal to 180°, the first transistor M1 and the second transistor M2 are asynchronously turned on, and the third transistor M3 and the fourth transistor M4 are asynchronously turned on. Further, by setting the pulse generating unit 1113 to adjust the dead time of the first driving control signal S31 and the second driving control signal S32 according to the frequency of the sinusoidal modulation signal S2, so that the first driving control signal S31 and the second driving control signal S32 remain at the invalid level in the dead time, the first transistor M1 and the second transistor M2 are controlled to be turned on at different times, and the third transistor M3 and the fourth transistor M4 are controlled to be turned on at different times, so as to avoid short circuit caused by the simultaneous turning on of the first transistor M1 and the second transistor M2, and avoid short circuit caused by the simultaneous turning on of the third transistor M3 and the fourth transistor M4, so as to effectively avoid short circuit failure.

In addition, the control unit 1111 can also detect the fault condition of the ultrasonic driving device 01 according to the power detection signal Q0, and feed back the fault detection information to the client in real time through the communication interface A1.

As shown in Figure 14 The driving control module 100 further includes an abnormality detection circuit 140; the input end of the abnormality detection circuit 140 is electrically connected with the output end of the driving output sub-module 130, and the output end of the abnormality detection circuit 140 is electrically connected with the state input end of the adjustment control sub-module 110; the abnormality detection circuit 140 is used for obtaining the voltage detection signal and the current detection signal, and generating a working state indication signal according to the voltage detection signal and / or the current detection signal, so as to output to the adjustment control sub-module 110; the adjustment control sub-module 110 is further used for determining the output state of the voltage adjustment control signal and the driving control signal according to the working state indication signal, and outputting the working state indication signal to the communication interface A1.

[0163] Specifically, the abnormality detection circuit 140 can acquire the voltage detection signal and the current detection signal to detect abnormality of the voltage and / or current of the ultrasonic driving signal S0. The abnormality detection circuit 140 can generate a working state indication signal according to at least one of the voltage detection signal and the current detection signal, and output the working state indication signal to the adjustment control submodule 110. The adjustment control submodule 110 can control the output state of the voltage adjustment control signal and the driving control signal according to the working state indication signal, so as to stop outputting the voltage adjustment control signal and the driving control signal in time when it is determined that the voltage detection signal and / or the current detection signal is abnormal, so that the driving output submodule 130 stops outputting the ultrasonic driving signal S0. Meanwhile, the adjustment control submodule 110 can also send the working state indication signal to the communication interface A1 in real time, so as to feed back the working state of the ultrasonic driving device 01 to the client in real time.

[0164] The working state indication signal comprises an abnormality alarm signal; the abnormality detection circuit 140 is further configured to output the abnormality alarm signal to the adjustment control submodule 110 when the amplitude of the voltage detection signal is greater than a first preset amplitude, and / or, the effective value of the voltage detection signal is greater than a first preset effective value, and / or, the effective value of the current detection signal is greater than a second preset effective value, and / or, the amplitude of the current detection signal is greater than a second preset amplitude; and the adjustment control submodule 110 is further configured to stop outputting the voltage adjustment control signal and the driving control signal, and output the abnormality alarm signal to the communication interface A1 when the working state indication signal is the abnormality alarm signal.

[0165] In a possible implementation, the RMS (Root Mean Square, root mean square) method can be used to calculate the voltage effective value and / or the current effective value, so as to obtain the effective value of the voltage detection signal and / or the effective value of the current detection signal.

[0169] In a possible implementation manner, the voltage sampling circuit 300 can include a resistance voltage dividing circuit (two resistors) and a first amplifier. After the ultrasonic driving signal S0 is sampled by the resistance voltage dividing circuit, the voltage signal obtained is amplified by the first amplifier to obtain the voltage detection signal, so as to realize impedance isolation, reduce the influence of the input impedance of the subsequent circuit on the sampling accuracy, and make the voltage detection signal within the ADC sampling range of the power detection module 200 and / or the abnormality detection circuit 140. Alternatively, the voltage sampling circuit 300 can include a voltage sensor, which can output after reducing the ultrasonic driving signal S0 by a first preset ratio, so that the output voltage detection signal is within the ADC sampling range of the power detection module 200 and / or the abnormality detection circuit 140.

[0170] In a possible implementation manner, the amplification ratio of the first amplifier can be 1:1, 1:3 or 1:5, which is not limited herein.

[0171] The current sampling circuit 400 can include a sampling resistor and a second amplifier, the ultrasonic drive signal S0 is current sampled through the sampling resistor, and the acquired voltage is amplified by the second amplifier according to a second preset ratio to generate a current detection signal, so that the current detection signal is within the ADC sampling range of the power detection module 200 and / or the abnormality detection circuit 140. Alternatively, the voltage sampling circuit 300 can include a current sensor, which can directly output a voltage signal representing the current after current sampling and reduction of the ultrasonic drive signal S0 according to a second preset ratio, so that the output current detection signal is within the ADC sampling range of the power detection module 200 and / or the abnormality detection circuit 140.
