Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically to an integrated surgical system and drive system for delivering energy to surgical equipment. Background Technology

[0002] High-frequency electrosurgical units (HFEMUs) and ultrasonic scalpels are now widely used in clinical surgery. HFEMUs utilize the thermal effect generated by high-frequency current passing through human tissue to cut and coagulate it. Ultrasonic scalpels use the ultrasonic mechanical vibration energy of the instrument tip to cut and coagulate tissue for hemostasis. HFEMUs typically have a wide output power range, making them highly efficient for skin and tissue cutting, but they cause significant thermal damage to the surrounding tissue, making them unsuitable for delicate surgical procedures. Ultrasonic scalpels have lower output energy, causing far less damage to the surrounding tissues than HFEMUs, and can be safely used for dissection and cutting near important blood vessels. These two energy systems each have their advantages and disadvantages, and are sometimes used simultaneously or at different times during the same surgery to achieve efficient and smooth operation.

[0003] In the use of ultrasonic scalpels and electrosurgical units, to ensure successful output of ultrasonic energy and / or electrical energy, a power amplifier is first needed to convert the energy into a high-quality, constant sinusoidal current signal to drive the subsequent impedance device and achieve the desired function. During this process, the power amplifier receives a feedback compensation signal and outputs a pre-set sinusoidal current signal. The quality of the feedback compensation signal directly determines the quality and distortion of the subsequent sinusoidal current output. Therefore, to ensure a high-quality and constant sinusoidal current output signal, the quality of the feedback compensation signal must also be carefully considered.

[0004] The drive signals generated by the power amplifiers used in existing ultrasonic scalpels and electrosurgical units are typically produced through digital-to-analog conversion (DAC), or by superimposing a DC bias on top of the DAC to reduce the nonlinearity of the output current. All of these methods result in crossover distortion, which can easily lead to distortion of the current waveform after passing through the power amplifier. This usually requires software algorithms to correct the distortion and meet the requirements of the downstream impedance device. However, this approach has many limitations and drawbacks in practical applications of ultrasonic scalpels and electrosurgical units. Summary of the Invention

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0060] In some embodiments of the present invention, the drive system of the present invention is used in specific surgical systems, such as surgical systems that allow the provision of electrosurgical and ultrasonic scalpel functions in a single device system; or in other embodiments, there are integrated surgical systems that integrate electrosurgical and ultrasonic scalpels in the same device, which can support on-demand time-sharing output of ultrasonic energy and high-frequency electrosurgical energy; and even in some embodiments, integrated surgical systems that integrate electrosurgical and ultrasonic scalpels in the same device can also support the synchronous output of ultrasonic energy and high-frequency electrosurgical energy, achieving faster tissue cutting and coagulation.

[0061] Furthermore, in some embodiments of surgical systems related to the present invention, the drive system of the present invention can be applied to ultrasonic scalpel surgical systems, electrosurgical surgical systems, and any surgical medical system that requires this or similar form of energy output. Of course, such applications include, but are not limited to, surgical systems that perform one specific form of energy output or surgical systems that perform multiple forms of energy output.

[0062] Referring to Figure 1(a), in some embodiments, an integrated surgical system (hereinafter referred to as the integrated surgical system) for delivering energy to a surgical device includes a voltage conversion unit 10, a second power amplifier unit 23, an arithmetic and driving unit 40, and an energy output port 100; in some embodiments, referring to Figure 1(b), the integrated surgical system also includes a first power amplifier unit 21, which will be described in detail below.

[0063] In some embodiments, the energy output port 100 is used to deliver energy to surgical devices.

[0064] In some embodiments, referring to FIG1(c), the energy output port 100 includes an electrosurgical output port 50 and / or an ultrasonic scalpel output port 60. The electrosurgical output port 50 is used to deliver energy to the electrosurgical unit, such as high-frequency electrosurgical energy. The ultrasonic scalpel output port 60 is used to deliver energy to the ultrasonic scalpel, such as low-frequency ultrasonic scalpel energy.

[0065] In some embodiments, referring to FIG1(d), the electrosurgical output port 50 includes a single terminal 51, a single terminal 52, a neutral terminal 53, and a dual terminal 54, which will be further described below.

[0066] In some embodiments, the voltage conversion unit 10 is used to convert the input voltage into a DC voltage.

[0067] In some embodiments, the voltage conversion unit 10 is a voltage conversion circuit, that is, the voltage conversion unit 10 includes a positive input terminal, a negative input terminal, a positive output terminal and a negative output terminal. The voltage conversion unit 10 receives the input voltage through the positive input terminal and the negative input terminal, and outputs DC power through the positive output terminal and the negative output terminal.

[0068] In some embodiments, the voltage conversion unit 10 is capable of outputting adjustable direct current (DC). In some embodiments, under the control of the arithmetic and drive unit 40, the voltage conversion unit 10 outputs a desired amount of DC, for example, the voltage conversion unit 10 converts the input voltage into a corresponding amount of DC based on a first control signal output by the arithmetic and drive unit 40. In some embodiments, the first control signal is a digital signal. In some embodiments, the voltage conversion unit 10 receives a negative voltage and outputs it as an adjustable positive voltage; for example, the voltage conversion unit 10 receives a -48V input and can output DC from 0 to 350V. In some embodiments, the voltage conversion unit 10 converts alternating current (AC) to DC. In some embodiments, the voltage conversion unit 10 is an HVDC, i.e., a high-voltage direct current (HVDC) unit.

[0069] Referring to Figure 2(a), in some embodiments, the voltage conversion unit 10 includes a boost circuit 11; in some embodiments, the boost circuit 11 is used to receive a negative DC voltage and convert the negative DC voltage into a positive DC voltage of a corresponding magnitude according to a first control signal. Referring to Figures 2(b), 2(c), and 2(d), in some embodiments, the boost circuit 11 includes one or more boost branches 12; the boost branch 12 includes an energy conversion inductor L, a charging switch SW1, and a discharging switch SW2, which are used to switch on and off according to the first control signal to charge and discharge the energy conversion inductor L, thereby boosting the voltage. Figure 2(c) is an example including one boost branch 12, and Figure 2(d) is an example including two boost branches 12; multiple boost branches 12 can increase output power and reduce ripple.

[0070] In some embodiments, one end of the energy conversion inductor L is grounded, and the other end is connected to the voltage input terminal of the boost circuit 11 through the charging switch SW1. The voltage input terminal of the boost circuit 11 is used to receive negative DC voltage. The non-grounded end of the energy conversion inductor L is also connected to the voltage output terminal of the boost circuit 11 through the discharge switch SW2. The voltage output terminal of the boost circuit 11 is used to output positive DC voltage.

[0071] During operation, the charging switch SW1 and the discharging switch SW2 are turned on alternately, and they will not be turned on at the same time. The output voltage is regulated by adjusting their duty cycle. Specifically, when the charging switch SW1 is turned on and the discharging switch SW2 is turned off, the energy conversion inductor L is charged by the input negative DC voltage. When the charging switch SW1 is turned off and the discharging switch SW2 is turned on, the energy conversion inductor L is discharged by the input negative DC voltage.

[0072] In some embodiments, the charging switch SW1 includes a three-terminal transistor or a diode; in some embodiments, the discharging switch SW2 includes a three-terminal transistor or a diode.

[0073] In some embodiments, the boost circuit 11 further includes an input capacitor Cin and / or an output capacitor Cout; one end of the input capacitor Cin is grounded and the other end is connected to the voltage input terminal of the boost circuit 11; one end of the output capacitor Cout is grounded and the other end is connected to the voltage output terminal of the boost circuit 11.

[0074] In some embodiments, referring to FIG2(e), the boost branch 12 further includes a current detection circuit I1, which is connected in series with the charging switch SW1 and is used to output a detection current; the arithmetic and driving unit 40 is used to generate or adjust the first control signal according to the detection current.

[0075] In some embodiments, the boost circuit 11 is a boost circuit.

[0076] In some embodiments, the positive DC voltage output by the boost circuit 11 ranges from 0 to a preset value; in some embodiments, the preset value is 350V.

[0077] In some embodiments, the positive DC voltage referred to herein includes 0.

[0078] In some embodiments, the input negative DC voltage is -48V.

[0079] A wide-range adjustable positive voltage with a minimum voltage of 0 is achieved by using negative voltage input, thereby realizing wide dynamic range power regulation.

[0080] In adjustable power supply systems that deliver energy to surgical equipment, the front end typically has an AC-to-DC converter, which then outputs a wide-range adjustable positive voltage based on the DC voltage. Some solutions involve conversion based on PFC (Power Factor Correction) using a flyback converter. However, since the output voltage of the AC-to-DC converter is generally neither very low nor very high, the former increases the impact of leakage inductance in the flyback converter, resulting in low efficiency, while the latter makes the output voltage adjustment range of traditional boost circuits too narrow (it can only boost voltage). In some embodiments of this application, a wide-range adjustable positive voltage output with a minimum voltage of 0 is achieved through a negative power supply input, with high efficiency, overcoming the disadvantages of both methods and combining their advantages.

[0081] In some embodiments of this application, compared with the flyback scheme, the isolation transformer is eliminated, resulting in higher efficiency; compared with the four-switch scheme, the output voltage can be higher, and the number of switches is less, resulting in lower cost; compared with the traditional boost scheme, the output voltage adjustment range is wider, and it can support 0 positive voltage output.

[0082] In some embodiments, the voltage conversion unit 10 includes an inductor and two switching devices, all three devices having one end connected together. The other end of the inductor is grounded, and the other ends of the two switching devices serve as input and output, respectively. The switching times of the two switching devices are staggered to achieve the voltage conversion function. Figure 2(f) shows an example of the voltage conversion unit 10, which includes an inductor L1, a transistor Q1, a diode D1, and a capacitor C1. One end of the inductor L1 is grounded, and the other end is connected to the anode of the diode D1. The cathode of the diode D1 is connected to one end of the capacitor C1, and the other end of the capacitor C1 is grounded. The anode of the diode D1 is also connected to the first terminal of the transistor Q1. The control terminal of the transistor Q1 is controlled by the arithmetic and driving unit 40, for example, to receive signals output by the arithmetic and driving unit 40, such as the first control signal mentioned above. The second terminal of the transistor Q1 serves as the input terminal of the voltage conversion unit 10, used to receive the input voltage. The cathode of the diode D1 serves as the output terminal of the voltage conversion unit 10, used to output adjustable DC voltage. In the example shown in Figure 2, diode D and transistor Q1 act as two switching devices. Under the control of the arithmetic and driving unit 40, their turn-on times are staggered, which enables the voltage conversion function.

[0083] It should be noted that the transistors mentioned in this article are three-terminal devices, which can be transistors of any structure, such as bipolar junction transistors (BJTs) or field-effect transistors (FETs). When the transistor is a bipolar junction transistor, its control electrode refers to the gate of the bipolar junction transistor, and the first electrode can be the collector or emitter of the bipolar junction transistor. The corresponding second electrode can be the emitter or collector of the bipolar junction transistor. In practical applications, the "emitter" and "collector" can be interchanged according to the signal flow direction. When the transistor is a field-effect transistor, its control electrode refers to the gate of the field-effect transistor, and the first electrode can be the drain or source of the field-effect transistor. The corresponding second electrode can be the source or drain of the field-effect transistor. In practical applications, the "source" and "drain" can be interchanged according to the signal flow direction.

[0084] In the case where the integrated surgical system specifically includes a first power amplifier unit 21, the voltage conversion unit 10 is used to drive the DC voltage of the first power amplifier unit 21.

[0085] In the case where the integrated surgical system specifically has a second power amplifier unit 23, the voltage conversion unit 10 is used to supply the DC voltage to the second power amplifier unit 23 for operation, that is, to convert the input voltage into the operating voltage of the second power amplifier unit 23, which is a DC voltage.

[0086] In some embodiments, the first power amplifier unit 21 is used to convert the DC power output by the voltage conversion unit 10 into AC power and amplify it, then provide it to the energy output port 100, for example, to the electrosurgical output port 50 to power the electrosurgical device. For example, under the control of the arithmetic and driving unit 40, the first power amplifier unit 21 converts the DC power output by the voltage conversion unit 10 into AC power and amplifies it. In some embodiments, the first power amplifier unit 21 is used to convert the DC power output by the voltage conversion unit 10 into AC power and amplify it according to a second control signal output by the arithmetic and driving unit 40. In some embodiments, the second control signal is a digital signal. In some embodiments, the first power amplifier unit 21 converts the DC power output by the voltage conversion unit 10 into a square wave voltage or square wave signal.

[0087] In some embodiments, the first power amplifier unit 21 is a full-bridge power amplifier circuit. Figure 3 An example of the first power amplifier unit 21 includes transistors Q2, Q3, Q4, and Q5. The first terminal of transistor Q2 is connected to the first terminal of transistor Q3 and is used to receive the DC power output from the voltage conversion unit 10. The second terminal of transistor Q2 is connected to the first terminal of transistor Q4 and is used as the first output terminal of the first power amplifier unit 21. The second terminal of transistor Q3 is connected to the first terminal of transistor Q5 and is used as the second output terminal of the first power amplifier unit 21. The second terminals of transistors Q4 and Q5 are both grounded. The control terminals of transistors Q2, Q3, Q4, and Q5 are all controlled by the arithmetic and driving unit 40, for example, they are all used to receive signals output by the arithmetic and driving unit 40, such as the second control signal mentioned above, which can be a pulse width modulation signal. The first power amplifier unit 21 outputs through its first and second output terminals, for example, the AC power output after converting the DC power output from the voltage conversion unit 10 into AC power and amplifying it, or in other words, the output signal. In some embodiments, an LC series circuit is also connected between the two output terminals of the full-bridge power amplifier circuit. For example, an LC series circuit is connected between the second terminal of transistor Q2 and the second terminal of transistor Q3. This helps the full-bridge power amplifier circuit to achieve soft switching.

[0088] In some embodiments, the second power amplifier unit 23 receives at least two split-wave signals generated by the arithmetic and driving unit 40 and converts them into a desired target waveform signal to provide to the energy output port 100, for example, to the ultrasonic scalpel output port 60 to deliver energy to the ultrasonic scalpel. The second power amplifier unit 23 receives power from the voltage conversion unit 10; in other words, the second power amplifier unit 23, powered by the DC power output from the voltage conversion unit 10, converts the aforementioned at least two split-wave signals into the desired target waveform signal.

[0089] In some embodiments, the second power amplifier unit 23 is a linear power amplifier circuit.

[0090] In some embodiments, the output of the second power amplifier unit 23 is a desired target waveform signal, such as a periodic signal of a complete sine wave, without crossover. In some embodiments, the second power amplifier unit 23 receives two split-wave signals, such as two drive current signals—hereinafter referred to as... Figure 8 For example, two current signals I A and current signal I B The second power amplifier unit 23 amplifies the signal and outputs it, resulting in, for example, a current signal K*(I). A -I B ), where K is the amplification factor. In some embodiments, the signal received by the second power amplifier unit 23 is an analog signal, such as the current signal I mentioned above. A and current signal I B They are all analog signals.

[0091] The second power amplifier unit 23 is, for example, subjected to current signal I. A and current signal I A Driven by two drive signals, output K*(I) A -I B ), guarantee I A -I B It is a complete sine wave, without crossover distortion, and the waveform distortion does not need to be corrected to achieve a relatively ideal result. It can be implemented by hardware circuits and has a low cost, which will be explained in more detail below.

[0092] In some embodiments, please refer to Figure 4(a) or Figure 4(b), the integrated surgical system further includes a first isolation transformation unit 31 and / or a second isolation transformation unit 33, which will be described in detail below.

[0093] In some embodiments, the first isolation conversion unit 31 is used to isolate and convert the AC power output from the first power amplifier unit 21 and then provide it to the energy output port 100, such as the electrosurgical output port 50. In some embodiments, the first isolation conversion unit 31 is used to resonate, isolate, and convert the AC power output from the first power amplifier unit 21 and then provide it to the energy output port 100, such as the electrosurgical output port 50.

[0094] In the example where the first power amplifier unit 21 is implemented by a full-bridge power amplifier circuit, the full-bridge power amplifier circuit is used to convert the DC power output by the voltage conversion unit 10 into a square wave voltage; the first isolation conversion unit 31 is used to filter the square wave voltage into an AC voltage, such as a sine wave voltage, and provide it to the energy output port 100, such as the electric knife output port 50, after resonance, isolation and conversion.

[0095] In some embodiments, the first isolation conversion unit 31 is implemented by a transformer.

[0096] The above is a description of the first isolation transformation unit 31. The second isolation transformation unit 33 will be described below.

[0097] In some embodiments, the second isolation and transformation unit 33 is used to isolate and transform the signal output by the first power amplifier unit 23, such as the desired target waveform signal, and then provide it to the energy output port 100, such as the ultrasonic scalpel output port 60. That is, before the desired target waveform signal is provided to the energy output port 100, the second isolation and transformation unit 33 first isolates and transforms the desired target waveform signal and then provides it to the energy output port 100.

[0098] In some embodiments, the second isolation conversion unit 33 is implemented by a transformer.

[0099] Please refer to Figure 5 Some embodiments of the integrated surgical system also include a sampling unit 49, which will be described in detail below.

[0100] In some embodiments, the sampling unit 49 is used to sample the input or output of the first isolation conversion unit 31 to obtain a first sampled electrical signal; the sampling unit 49 is also used to sample the input or output of the second isolation conversion unit 33 to obtain a second sampled electrical signal. In some embodiments, the first sampled electrical signal includes at least one of voltage, current, and power. In some embodiments, the second sampled electrical signal includes at least one of voltage, current, and power. In some embodiments, the arithmetic and driving unit 40 adjusts a first control signal and / or a second control signal according to the first sampled electrical signal. In some embodiments, the arithmetic and driving unit 40 adjusts a third initial signal according to the second sampled electrical signal.

[0101] Please refer to Figure 6 In some embodiments, the first isolation conversion unit 31 further includes at least one of a series-parallel resonant circuit 91, a common-mode filter circuit 92, and a shutdown absorption circuit 93, which will be described in detail below.

[0102] In some embodiments, the series-parallel resonant circuit 91 is used to filter the AC output of the first power amplifier unit 21, for example, filtering a square wave into a sine wave before outputting it. In embodiments where the power amplifier unit 20 includes the first power amplifier unit 21, the common-mode filter circuit 92 is used to filter out the common-mode signal from the AC output of the first power amplifier unit 21. In embodiments where the power amplifier unit 20 includes the first power amplifier unit 21, the shutdown absorption circuit 93 is used to prevent oscillation after the first power amplifier unit 93 is turned off.

[0103] Please refer to Figure 7The example shows a circuit diagram of a voltage conversion unit 10, a first power amplifier unit 21, and a first isolation conversion unit 31. The circuit diagram of the first isolation conversion unit 31 includes a circuit implementation structure of a series-parallel resonant circuit 91, a common-mode filter circuit 92, a shutdown absorption circuit 93, and a first isolation unit 33.

[0104] Please refer to Figure 8 The integrated surgical system in some embodiments also includes an impedance matching circuit 94, which in some embodiments is connected between the second power amplifier unit 23 and the second isolation conversion unit 23 for impedance matching.

[0105] In some embodiments, the arithmetic and driving unit 40 is used to generate and / or adjust any one, any two, or all three of the first control signal, the second control signal, and the third initial signal, as described in detail below.

[0106] In some embodiments, the arithmetic and driving unit 40 receives control parameters input by the user through the user input unit (not shown in the figure).

[0107] In some embodiments, the arithmetic and driving unit 40 is used to generate a first control signal, a second control signal, and a third initial signal according to control parameters.

[0108] In some embodiments, the arithmetic and driving unit 40 is used to adjust any one, any two, or all three of the first control signal, the second control signal, and the third initial signal according to the sampled electrical signal.

[0109] In some embodiments, the arithmetic and driving unit 40 is used to adjust the first control signal and / or the second control signal according to the first sampled electrical signal, and to adjust the third initial signal according to the second sampled electrical signal.

[0110] Please refer to Figure 9(a). In some embodiments, the arithmetic and driving unit 40 includes a processor 41, a waveform generator 43, a digital-to-analog converter 45, and a waveform divider 47, which will be described in detail below.

[0111] In some embodiments, the processor 45 is used to generate a first control signal. In some embodiments, referring to FIG9(b), the arithmetic and driving unit 40 further includes a digital-to-analog converter 46, used to convert the first control signal from a digital signal into an analog signal and then output it to the voltage conversion unit 10.

[0112] In some embodiments, the processor 45 controls the waveform generator 43 to generate a second digital signal waveform as a second control signal.

[0113] In some embodiments, the processor controls the waveform generator 43 to generate a third digital signal waveform, and the digital-to-analog converter 45 converts the third digital signal waveform into a third analog signal waveform as the third initial signal; the waveform divider 47 divides the third analog signal waveform, or the third initial signal, to obtain the third signal. In some embodiments, the waveform divider 47 divides the third analog signal waveform into at least two divided signals as the aforementioned third signal.

[0114] In some embodiments, the processor 41 receives input parameters, such as control parameters, from the user input unit, calculates parameters such as the amplitude, frequency, and duty cycle of the driving waveform, and sends the waveform data or waveform parameters to the waveform generator 43 to generate the required driving waveform. Depending on the output mode, the analog signal waveform is used to drive the second power amplifier unit 23, for example, a linear power amplifier, while the digital signal waveform is used to drive the first power amplifier unit 21, for example, a full-bridge power amplifier. The processor 41 calculates relevant electrical parameters such as impedance, power, and phase difference based on the sampled electrical signal fed back by the sampling unit 49, and adjusts the output waveform and the output voltage of the voltage conversion unit 10 in real time to achieve the required energy output.

[0115] Please refer to Figure 10 The calculation and drive unit 40 splits at least two waveforms into two signals through the waveform splitting unit 47, such as the tufted wave (or half wave or other forms of waveform, which are only illustrative examples) for example, S11 and S12. Then, signals S11 and S12 are converted (e.g., amplified) by the second power amplifier unit 23 to obtain signals S21 and S22. After combining signals S21 and S22, the target waveform signal (e.g., a sine wave signal) is obtained. Due to the waveform distortion during the waveform splitting, conversion and synthesis process, the final synthesized waveform has a certain degree of crossover distortion. On the one hand, software correction of this distortion has a certain lag, and on the other hand, it is necessary to modify the initial third analog signal waveform, that is, to change the third analog signal waveform generated by the waveform generator 43 and the digital-to-analog converter unit 45 through feedback. This is not conducive to the use of surgical equipment (or surgical instruments, such as the ultrasonic scalpel and electrosurgical unit mentioned in this article).

[0116] In some embodiments, hardware feedback is introduced to enable the second power amplifier unit 23 to finally output the desired target waveform signal, such as a desired sine wave signal. The desired sine wave signal can typically be a complete sine wave signal; there is no or almost no crossover distortion, and the waveform distortion does not need to be corrected to achieve a relatively ideal result. It can be implemented by hardware circuitry and has a low cost, which will be explained in detail below.

[0117] In some embodiments, please refer to Figure 11(a) or Figure 12(a), the second power amplifier unit 23 includes a signal conversion unit 25, a hardware feedback unit 26 and a waveform synthesis unit 27, which will be described in detail below.

[0118] In some embodiments, the number of signal conversion units 25 is the same as the number of split-wave signals. Each signal conversion unit 25 is used to receive one split-wave signal and convert it for output. The waveform synthesis unit 27 is used to receive the outputs of each signal conversion unit 25 and synthesize them into one output, which is the output of the second power amplifier unit 23. Therefore, the output of the waveform synthesis unit 27 is the target waveform signal.

[0119] In some embodiments, the signal conversion unit 25 performs conversion of the split-wave signal, including but not limited to signal amplification.

[0120] The hardware feedback unit 26 is introduced to make the target waveform signal output by the waveform synthesis unit 27 the desired target waveform signal, such as the desired sine wave signal; that is, the hardware feedback unit 26 is used to feed back the signal received at its input terminal to its output terminal, so that the target waveform signal output by the waveform synthesis unit 27 is the desired target waveform signal, and the desired sine wave signal is used to provide the energy output port 100.

[0121] In some embodiments, referring to FIG11(a), the number of hardware feedback units 26 is one, the input terminal of the hardware feedback unit 26 is used to connect to the output terminal of the waveform synthesis unit 27, and the output terminal of the hardware feedback unit 26 is used to connect to the input terminal of the waveform division unit 47.

[0122] In some embodiments, please refer to Figure 11(b) for an example of a second power amplifier unit 23, wherein the signal conversion unit 25 may include operational amplifiers, such as D1 to Dn in the figure, where n is a number; the hardware feedback unit 26 includes transistors and resistors.

[0123] In some embodiments, referring to FIG12(a), the number of hardware feedback units 26 is the same as the number of signal conversion units 25. Each hardware feedback unit 26 corresponds to one signal conversion unit 25. The input terminal of each hardware feedback unit 26 is connected to the output terminal of its corresponding signal conversion unit 25, and the output terminal of each hardware feedback unit 26 is connected to the input terminal of its corresponding signal conversion unit 25. In some embodiments, the hardware feedback unit 26 is used to ensure that the output of its corresponding signal conversion unit 25 meets expectations, so that the target waveform signal output by the waveform synthesis unit 27 is the desired target waveform signal.

[0124] In some embodiments, please refer to Figure 12(b) or Figure 12(c) for an example of a second power amplifier unit 23. The signal conversion unit 25 may include operational amplifiers D, such as D1 to Dn, where n is a number; the hardware feedback unit 26 includes transistors and resistors. In some embodiments, a hardware feedback unit 26 is introduced. After sampling and identifying the output signal of the signal conversion unit 25, the hardware feedback unit 26 feeds this output signal back to the signal conversion unit 25, allowing the signal conversion unit to compare it with the corresponding input split-wave signal and adjust its own output signal through continuous feedback adjustment.

[0125] In some embodiments, the hardware feedback unit 26 includes one or more of a power amplifier circuit, a resistor, a capacitor, an inductor, a diode, or a transistor.

[0126] It should be noted that the waveform splitter and target waveform are illustrated in Figures 11(a), 11(b), 12(a), 12(b), and 12(c) as examples, but this is only for illustrative purposes and does not mean that the waveform splitter and target waveform can only be shown in this way.

[0127] Please refer to Figure 13 Some embodiments of the integrated surgical system also include a switching assembly 70 for turning the power supply on and off the energy output port 100, such as turning the power supply on and off the electrosurgical output port 50 and the ultrasonic scalpel output port 60.

[0128] In some embodiments, the switch assembly 70 is a manual switch assembly, used by the user to manually turn the power supply on and off the electrosurgical output port 50 and the ultrasonic scalpel output port 60; for example, through the manual switch assembly 70, the user can turn on the electrosurgical output port 50 to enable power supply to the electrosurgical unit; through the manual switch assembly 70, the user can turn off the electrosurgical output port 50 to prevent the electrosurgical unit from receiving power from the electrosurgical output port 50; through the manual switch assembly 70, the user can turn on the ultrasonic scalpel output port 60 to enable power supply to the ultrasonic scalpel; through the manual switch assembly 70, the user can turn off the ultrasonic scalpel output port 60 to prevent the ultrasonic scalpel from receiving power from the electrosurgical output port 50.

[0129] In some embodiments, the electrosurgical unit can be fixedly connected to the electrosurgical unit output port 50 via a cable.

[0130] In some embodiments, the electrosurgical unit is pluggably connected to the electrosurgical unit output port 50.

[0131] In some embodiments, the ultrasonic scalpel can be fixedly connected to the ultrasonic scalpel output port 60 via a cable.

[0132] In some embodiments, the ultrasonic scalpel is pluggably connected to the ultrasonic scalpel output port 60.

[0133] In some embodiments, the electrosurgical output port 50 and the ultrasonic scalpel output port 60 can be the same port, and both the electrosurgical and ultrasonic scalpels are pluggably connected to this port.

[0134] In some embodiments, the electrosurgical output port 50 and the ultrasonic scalpel output port 60 can be the same port. The integrated surgical system can provide both electrosurgical energy and ultrasonic scalpel energy, but only one type of energy can be output at a time. The energy output is determined in a preemptive manner. In some embodiments, the energy conversion can be accomplished by the arithmetic and driving unit 40 controlling the switching component 70.

[0135] Please refer to Figure 14 This is an example of an integrated surgical system. Figure 14 The integrated surgical system shown supports one ultrasonic scalpel energy output, two monopolar electrosurgical energy outputs, and one bipolar electrosurgical energy output. As shown in the figure, the power output section of this integrated surgical system consists of two parts: a high-frequency electrosurgical power generation circuit mainly composed of a first power amplifier unit 21 (e.g., a full-bridge power amplifier), a first isolation conversion unit 31 (e.g., a transformer T1), and related peripheral components; and an ultrasonic scalpel power drive circuit mainly composed of a second power amplifier unit 23 (e.g., a linear power amplifier), and a first isolation conversion unit 33 (e.g., a transformer T2). A voltage conversion unit 10 (e.g., a high-voltage DC power supply unit (HVDC)) serves as the energy source, simultaneously powering both the full-bridge and linear power amplifiers. Sampling units 49 (e.g., sensors S1 and S2) are used to collect voltage, current, and power signals from the electrosurgical and ultrasonic scalpel power output circuits, respectively. After analysis by the calculation and drive unit 40, the sensor signals are used to drive and control the aforementioned two power amplifiers and the HVDC. Furthermore, a user input unit provides an operation interface allowing the user to control output parameters such as operating mode and power level. As can be seen from the aforementioned structure, the integrated surgical system samples the output energy signal through the sampling unit 49, and the calculation and drive unit 40 performs feedback adjustment on the two power amplifier circuits, which can achieve a stable output of the energy set by the user input unit.

[0136] exist Figure 14 In the example, the electrosurgical output port 50 includes the monopole 1, monopole 2, neutral electrode and bipole terminals shown in the figure, which can support two monopole electrosurgical energy outputs and one bipole electrosurgical energy output.

[0137] exist Figure 14In the example, K1 to K7 are instrument channel energy output selection switches, selectively connecting the electrosurgical and ultrasonic scalpel energy outputs to the corresponding instruments based on the instrument interface selected by the user and the excitation control input signal. Generally, the electrosurgical and ultrasonic scalpel energy outputs are time-division multiplexed. That is, when the electrosurgical power generation circuit and a certain electrosurgical instrument channel switch (K1, K2, K3 or K4 and K5) are closed to output energy, the ultrasonic power generation circuit is not working and the ultrasonic scalpel instrument channel switch is open, at which time the ultrasonic scalpel has no energy output; similarly, it is also possible to achieve ultrasonic scalpel energy output while electrosurgical energy is not output. Furthermore, since the electrosurgical power generation circuit and the ultrasonic scalpel power generation circuit are two independent circuits in this invention, it can also support the simultaneous output of at least two different energy instruments, that is, simultaneously outputting electrosurgical energy and ultrasonic scalpel energy.

[0138] Some embodiments of this application also disclose a drive system (hereinafter referred to as the drive system) for delivering energy to surgical devices. Please refer to... Figure 15 or Figure 16 The drive system may include a signal generation unit 48, a waveform division unit 47, a signal conversion unit 25, a hardware feedback unit 26, and a waveform synthesis unit 27, which will be described in detail below.

[0139] The signal generation unit 48 is used to generate a third initial signal, such as the third analog signal waveform described above. The waveform division unit 47 divides the third initial signal into at least two waveform division signals.

[0140] In some embodiments, the number of signal conversion units 25 is the same as the number of split-wave signals. Each signal conversion unit 25 is used to receive one split-wave signal and convert it for output. The waveform synthesis unit 27 is used to receive the outputs of each signal conversion unit 25 and synthesize them into one output, which is the output of the second power amplifier unit 23. Therefore, the output of the waveform synthesis unit 27 is the target waveform signal.

[0141] In some embodiments, the signal conversion unit 25 performs conversion of the split-wave signal, including but not limited to signal amplification.

[0142] The hardware feedback unit 26 is introduced to make the target waveform signal output by the waveform synthesis unit 27 the desired target waveform signal, such as the desired sine wave signal; that is, the hardware feedback unit 26 is used to feed back the signal received at its input terminal to its output terminal, so that the target waveform signal output by the waveform synthesis unit 27 is the desired target waveform signal, and the desired sine wave signal is used to provide the energy output port 100.

[0143] In some embodiments, there is one hardware feedback unit 26, the input of which is connected to the output of the waveform synthesis unit 27, and the output of which is connected to the input of the waveform division unit 47.

[0144] Figure 11(b) above shows an example of the implementation of signal conversion unit 25 and hardware feedback unit 26. Signal conversion unit 25 may include operational amplifiers, such as D1 to Dn in the figure, where n is a number. Hardware feedback unit 26 includes transistors and resistors.

[0145] In some embodiments, the number of hardware feedback units 26 is the same as the number of signal conversion units 25. Each hardware feedback unit 26 corresponds to one signal conversion unit 25. The input terminal of each hardware feedback unit 26 is connected to the output terminal of its corresponding signal conversion unit 25, and the output terminal of each hardware feedback unit 26 is connected to the input terminal of its corresponding signal conversion unit 25. In some embodiments, the hardware feedback unit 26 is used to ensure that the output of its corresponding signal conversion unit 25 meets expectations, so that the target waveform signal output by the waveform synthesis unit 27 is the desired target waveform signal.

[0146] The above Figure 12(b) or Figure 12(c) illustrates an example of the implementation of the signal conversion unit 25 and the hardware feedback unit 26. The signal conversion unit 25 may include operational amplifiers D, such as D1 to Dn, where n is a number; the hardware feedback unit 26 includes transistors and resistors. In some embodiments, the hardware feedback unit 26 is introduced. After sampling and identifying the output signal of the signal conversion unit 25, the hardware feedback unit 26 feeds this output signal back to the signal conversion unit 25, allowing the signal conversion unit to compare it with the corresponding input waveform divider signal and adjust its own output signal through continuous feedback adjustment.

[0147] In some embodiments, the hardware feedback unit 26 includes one or more of a power amplifier circuit, a resistor, a capacitor, an inductor, a diode, or a transistor.
