Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an integrated surgical system and integrated surgical instruments. 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 HFEMs, 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 generally used simultaneously in the same surgery to achieve efficient and smooth operation.

[0003] High-frequency electrosurgical energy systems and ultrasonic scalpel energy systems are typically two separate devices in the operating room. If simultaneous use is required during surgery, both devices must be placed around the operating table. Surgeons frequently switch between these systems to adjust energy output, causing inconvenience and potentially leading to confusion and surgical risks. Furthermore, operating room space is usually limited, and many other devices besides the energy systems need to be arranged simultaneously. Having two energy systems occupies even more space, complicating operating room management. Summary of the Invention

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0018] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0019] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0020] As mentioned above, high-frequency electrosurgical units and ultrasonic scalpels are now widely used in clinical surgery. High-frequency electrosurgical units utilize the thermal effect generated by high-frequency current passing through human tissue to achieve tissue cutting and coagulation; ultrasonic scalpels utilize the ultrasonic mechanical vibration energy of the instrument tip for hemostasis, cutting, and coagulation. High-frequency electrosurgical units can be used with different instruments to achieve monopolar and bipolar applications. The main difference between these two applications lies in the different ranges of high-frequency current flow through human tissue. In monopolar applications, the high-frequency current flows between the surgical electrode and the neutral electrode, traversing a larger area of ​​human tissue, typically suitable for efficient tissue cutting, superficial or deep coagulation, etc. In bipolar applications, the high-frequency current flows between the two electrodes of a bipolar instrument, traversing only a small area of ​​human tissue, typically used for rapid and precise tissue coagulation. High-frequency electrosurgical units have a wide output power range and are highly efficient for tissue cutting or coagulation, but they cause a larger area of ​​thermal damage to the surrounding tissue, making them unsuitable for surgical procedures requiring high thermal damage tolerance. Compared to high-frequency electrosurgical units, ultrasonic scalpels have lower energy output, resulting in significantly less thermal damage to surrounding tissues. This allows for safe application in the dissection and cutting of vital blood vessels without excessive damage. Monopolar, bipolar, and ultrasonic scalpels each have their advantages in clinical surgery, and they are typically used in combination depending on the surgical scenario. Even within the same surgery, monopolar, bipolar, or ultrasonic scalpels may be used at different times to ensure smooth surgical progress.

[0021] High-frequency electrosurgical energy systems and ultrasonic scalpel energy systems are typically two separate devices in the operating room. If simultaneous use is required during surgery, both devices must be positioned around the operating table. Surgeons frequently switch between these devices to adjust energy output, causing inconvenience and potentially leading to confusion and surgical risks. Furthermore, operating room space is usually limited, and many other devices besides the energy systems need to be arranged simultaneously. Having two energy systems occupies more space and complicates management. Additionally, if monopolar, bipolar, or ultrasonic scalpels are used simultaneously, frequent instrument changes are necessary to address different tissue conditions. This excessive number of instruments and frequent switching further complicates the procedure and reduces surgical efficiency.

[0022] In some embodiments of the present invention, an integrated surgical system is proposed that supports both high-frequency electrosurgical and ultrasonic scalpel functions through a single energy device. Furthermore, in some embodiments of the present invention, the same surgical instrument can be used to support both electrosurgical and ultrasonic scalpel applications. In addition to supporting electrosurgical applications, it can even further support monopolar electrosurgical and bipolar electrosurgical applications.

[0023] As can be seen, in some embodiments, by integrating two types of energy devices, platformization and miniaturization are achieved, reducing the number of operating room devices and space occupation, and improving the efficiency of operating room management.

[0024] Furthermore, in some embodiments, the electrosurgical unit and the ultrasonic scalpel are integrated into a single surgical instrument, reducing surgical interruptions caused by changing instruments during the operation and improving surgical efficiency.

[0025] In some embodiments, the integrated surgical instrument, while supporting electrosurgical and ultrasonic scalpel functions, can also support time-sharing output of three types of energy: monopolar electrosurgical, bipolar electrosurgical, and ultrasonic scalpel. Alternatively, it can support simultaneous output of bipolar electrosurgical and ultrasonic scalpel energy to adapt to a wider range of more flexible application needs.

[0026] Referring to Figures 1(a) and 1(b), the integrated surgical system in some embodiments includes a voltage conversion unit 10, a first power amplifier unit 21, a second power amplifier unit 23, an isolation conversion unit 30, an arithmetic and driving unit 40, an electrosurgical output port 50, an ultrasonic scalpel output port 60, and a switching assembly 70. The electrosurgical output port 50 is used to supply energy to the electrosurgical unit, and the ultrasonic scalpel output port 60 is used to supply energy to the ultrasonic scalpel. These will be described in detail below.

[0027] In some embodiments, the voltage conversion unit 10 is used to convert the input voltage into a DC voltage.

[0028] 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.

[0029] In some embodiments, the voltage conversion unit 10 is capable of outputting adjustable DC voltage. In some embodiments, under the control of the arithmetic and drive unit 40, the voltage conversion unit 10 outputs a desired amount of DC voltage; for example, the voltage conversion unit 10 converts the input voltage into a corresponding amount of DC voltage 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 voltage from 0 to 350V. In some embodiments, the voltage conversion unit 10 converts AC power to DC power. In some embodiments, the voltage conversion unit 10 is an HVDC, i.e., a high-voltage DC power unit.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] In some embodiments, the boost circuit 11 is a boost circuit.

[0037] 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.

[0038] In some embodiments, the positive DC voltage referred to herein includes 0.

[0039] In some embodiments, the input negative DC voltage is -48V.

[0040] 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.

[0041] 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 leakage inductance of the flyback converter, resulting in low efficiency, while the latter makes the output voltage adjustment range of the traditional boost circuit too narrow (it can only boost the voltage). In some embodiments of this application, a wide-range adjustable positive voltage output with a minimum voltage of 0 is achieved with high efficiency by inputting a negative power supply, overcoming the disadvantages of both and combining their advantages.

[0042] 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.

[0043] 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.

[0044] 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 terminal refers to the gate of the bipolar junction transistor. The first terminal can be the collector or emitter of the bipolar junction transistor, and the corresponding second terminal 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 terminal refers to the gate of the field-effect transistor. The first terminal can be the drain or source of the field-effect transistor, and the corresponding second terminal 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.

[0045] In some embodiments, the voltage conversion unit 10 is used to convert the input voltage into a DC voltage for driving the first power amplifier unit 21 or for supplying a DC voltage to the second power amplifier unit 23 according to the first control signal, that is, to convert the input voltage into the operating voltage of the second power amplifier unit 23, which is a DC voltage.

[0046] In some embodiments, the first power amplifier unit 21 converts the DC power output by the voltage conversion unit 10 into AC power and amplifies it, then provides it to the electrosurgical output port 50 after passing through the isolation conversion unit 30 to power the electrosurgical unit. 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 converts the DC power output by the voltage conversion unit 10 into AC power and amplifies 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.

[0047] 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.

[0048] In some embodiments, the second power amplifier unit 23 receives power from the voltage conversion unit 10, amplifies the third signal, outputs it, and then provides it to the ultrasonic scalpel output port 60 after passing through the isolation conversion unit 30 to power the ultrasonic scalpel. The third signal can be generated and output by the arithmetic and driving unit 40. In some embodiments, the output of the second power amplifier unit 23 is a periodic signal with a complete sine wave, without crossover. In some embodiments, the third signal includes two driving current signals, such as current signal I. A and current signal I BThe power amplifier unit 20 amplifies the third 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 third signal is an analog signal; for example, the third signal includes two analog drive current signals, such as the current signal I mentioned above. A and current signal I B They are all analog signals.

[0049] In some embodiments, the second power amplifier unit 23 is a linear power amplifier circuit.

[0050] In some embodiments, please refer to Figure 4 The isolation transformation unit 30 includes a first isolation transformation unit 31 and a second isolation transformation unit 33, which will be described in detail below.

[0051] 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 before providing it to 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 before providing it to the electrosurgical output port 50.

[0052] 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 electric knife output port 50 after resonance, isolation and conversion.

[0054] The above is a description of the first isolation transformation unit 31. The second isolation transformation unit 33 will be described below.

[0055] In some embodiments, the second isolation conversion unit 33 is used to isolate and convert the signal output by the second power amplifier unit 23 and then provide it to the ultrasonic scalpel output port 60.

[0056] In some embodiments, the second isolation conversion unit 33 is implemented by a transformer.

[0057] 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.

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.

[0065] In some embodiments, the processor 45 controls the waveform generator 43 to generate a second digital signal waveform as a second control signal.

[0066] 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.

[0067] 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.

[0068] In some embodiments, the switching assembly 70 includes a first set of switches 71 and a second set of switches 75. The first set of switches 71 is used to turn on and off the energy supply from the isolation conversion unit 30, for example, the first isolation conversion unit 31, to the electrosurgical output port 50. The second set of switches 75 is used to turn on and off the energy supply from the isolation conversion unit 30, for example, the second isolation conversion unit 33, to the ultrasonic scalpel output port 60.

[0069] In some embodiments, the electrosurgical output port 50 and the ultrasonic scalpel output port 60 share the same mechanical socket 100. When a surgical instrument is inserted into the mechanical socket 100, energy is delivered through the voltage conversion unit 10, the first power amplifier unit 21, and the isolation conversion unit 30, for example, the first isolation conversion unit 31; or, energy is delivered through the voltage conversion unit 10, the second power amplifier unit 23, and the isolation conversion unit 30, for example, the second isolation conversion unit 33.

[0070] In some embodiments, when a surgical instrument is inserted into the mechanical port 100, the computing and driving unit 40 identifies the type of the inserted surgical instrument through the mechanical port 100. The surgical instruments include at least two types: ultrasonic scalpel and electrosurgical scalpel. The surgical instruments are equipped with trigger buttons.

[0071] In some embodiments: If the type of surgical instrument currently identified is an electrosurgical unit, when the trigger button is triggered, the calculation and drive unit 40 controls the first set of switches 71 to be turned on, so as to deliver energy to the electrosurgical unit through the voltage conversion unit 10, the first power amplifier unit 21 and the isolation conversion unit 30, such as the first isolation conversion unit 31.

[0072] If the type of surgical instrument currently identified is an ultrasonic scalpel, when the trigger button is triggered, the calculation and drive unit 40 controls the second set of switches 72 to be turned on, so as to deliver energy to the ultrasonic scalpel through the voltage conversion unit 10, the second power amplifier unit 23 and the isolation conversion unit 30, such as the second isolation conversion unit 33.

[0073] In some embodiments, please refer to Figure 10 The electrosurgical unit further includes at least three types: monopolar electrosurgical unit, neutral electrosurgical unit, and bipolar electrosurgical unit. The electrosurgical unit output port 50 includes a single-pole terminal 51, a neutral terminal 53, and a dual-pole terminal 54. The first set of switches 71 includes a first set of sub-switches 72, a second set of sub-switches 73, and a third set of sub-switches 74. The first set of sub-switches 72 turns on and off the energy supply from the isolation conversion unit 30 to the single-pole terminal 51, the second set of sub-switches 73 turns on and off the energy supply from the isolation conversion unit 30 to the neutral terminal 53, and the third set of switches 74 turns on and off the energy supply from the isolation conversion unit 30 to the dual-pole terminal 54. Therefore: If the type of surgical instrument currently identified is a monopolar electrosurgical unit, when the trigger button is triggered, the calculation and drive unit 40 controls the first set of sub-switches 72 to be turned on, so as to deliver energy to the monopolar electrosurgical unit through the voltage conversion unit 10, the first power amplifier unit 21 and the isolation conversion unit 30, such as the first isolation conversion unit 31. If the type of surgical instrument currently identified is a neutral electrosurgical unit, when the trigger button is triggered, the calculation and drive unit 40 controls the second set of sub-switches 73 to be turned on, so as to deliver energy to the neutral electrosurgical unit through the voltage conversion unit 10, the first power amplifier unit 21 and the isolation conversion unit 30, such as the first isolation conversion unit 31. If the type of surgical instrument currently identified is a bipolar electrosurgical unit, when the trigger button is triggered, the arithmetic and drive unit controls the third sub-switch 74 to be turned on, so as to deliver energy to the bipolar electrosurgical unit through the voltage conversion unit 10, the first power amplifier unit 21 and the isolation conversion unit 30, such as the first isolation conversion unit 31.

[0074] The type of surgical instrument can be identified by the identification code stored in the internal memory of the surgical instrument. When the surgical instrument is inserted into the mechanical port 100, the computing and driving unit 40 is connected to the surgical instrument through a communication line, so that the computing and driving unit 40 can identify the type of surgical instrument.

[0075] In some embodiments, the mechanical port 100 can also be used to insert integrated surgical instruments, the integrated surgical instruments having at least two working forms: an electrosurgical unit and an ultrasonic scalpel.

[0076] In some embodiments, please refer to Figure 11 The integrated surgical instrument includes an ultrasonic transducer 01, a clamping nozzle 02, a waveguide rod 03, and a trigger button 04. The ultrasonic transducer 01 converts electrical signals into ultrasonic waves or mechanical vibrations. A second power amplifier unit 23 supplies energy to the ultrasonic transducer 01, enabling the integrated surgical instrument to function as an ultrasonic scalpel. A first power amplifier unit 21 provides energy to the clamping nozzle 02 and the waveguide rod 03. Specifically, when the positive output of the first power amplifier unit 21 or the positive output of the first isolation unit 31 provides energy to the waveguide rod 03, the integrated surgical instrument functions as a monopolar electrosurgical unit. When the positive output of the first power amplifier unit 21 or the positive output of the first isolation unit 31 provides energy to the waveguide rod 03, and the negative output of the first power amplifier unit 21 or the negative output of the first isolation unit 31 provides energy to the clamping nozzle 02, the integrated surgical instrument functions as a bipolar electrosurgical unit.

[0078] The computing and driving unit 40 acquires the working mode of the inserted integrated surgical instrument, which includes at least two modes: electrosurgical mode and ultrasonic scalpel mode.

If the integrated surgical instrument is currently in neutral electrosurgical mode, when the trigger button is triggered, the calculation and drive unit 40 controls the second set of sub-switches 73 to be turned on, so as to deliver energy to the integrated surgical instrument through the voltage conversion unit 10, the first power amplifier unit 21 and the isolation conversion unit 30, such as the first isolation conversion unit 31. If the integrated surgical instrument is currently in bipolar electrosurgical form, when the trigger button is triggered, the calculation and drive unit 40 controls the conduction of the third set of sub-switches 74 to deliver energy to the integrated surgical instrument through the voltage conversion unit 10, the first power amplifier unit 21 and the isolation conversion unit 30, such as the first isolation conversion unit 31.

[0080] In some embodiments, please refer to Figure 12 The integrated surgical system includes a switching component 05, which is used to switch the form of the integrated surgical instrument.

In some embodiments, the switching component 05 includes a foot switch. In some embodiments, the switching component 05 may include two foot switches: one foot switch switches the integrated surgical instrument from an electrosurgical unit to an ultrasonic scalpel, or vice versa, and the other foot switch switches the integrated surgical instrument between three forms: monopolar electrosurgical unit, neutral electrosurgical unit, and bipolar electrosurgical unit.
