Description

[Technical Field]

[0001] The present invention relates to the field of electrosurgery, and more particularly to surgical operating systems. [Background technology]

[0002] Electrocautery utilizes the energy output from an electrosurgical system to cut and coagulate tissue, where the thermal effect of the electric current causes tissue vaporization, which is the principle of cutting, and the thermal effect of the electric current causes denaturation and coagulation of tissue proteins, which is the principle of coagulation.

[0003] Currently, electrosurgical systems generally have monopolar and bipolar output capabilities.

[0004] In the prior art, as shown in FIG. 1, FIG. 1 illustrates the operating mode of the monopolar output function of a conventional electrosurgical system. This electrosurgical system includes a high-frequency power supply module, an electrosurgical pen, a circuit electrode, an active lead wire, and a circuit electrode lead wire. The specific operating flow of the operating mode of the monopolar output function of the electrosurgical system is that current flows from the electrosurgical pen through the human tissue and into the negative electrode plate attached to the patient, forming a circuit.

[0005] As shown in FIG. 2, FIG. 2 shows the operating mode of the bipolar output function of a conventional electrosurgical system. This electrosurgical system includes bipolar scissors, an active lead wire, and a circuit electrode lead wire. The specific operating flow of the operating mode of the bipolar output function of the electrosurgical system is that the bipolar instrument clamps tissue between the bipolar scissors (or bipolar tweezers, bipolar pliers) and passes an electric current through the human tissue to vaporize the tissue and coagulate hemostasis.

[0006] Therefore, conventional electrosurgical systems generally have monopolar output and bipolar output functions, respectively. Here, the advantage of monopolar output is that when comparing a monopolar electrosurgical knife using a monopolar output mode with a bipolar electrosurgical knife, the monopolar electrosurgical knife has a better cutting effect than a bipolar electrosurgical knife because the monopolar pen tip has a higher energy density.

[0007] However, because the electrosurgical pen is only one electrode in the entire current circuit, the power is not concentrated on the tissue to be coagulated, but passes through the tip of the pen and through a wider area of ​​human tissue before reaching the negative electrode end. Therefore, its coagulation effect is worse than that of a bipolar electrosurgical pen. Furthermore, it is difficult for a monopolar electrosurgical pen to penetrate deeply into the abdominal cavity and perform minimally invasive surgery under a laparoscope. When cutting, a monopolar electrosurgical pen cannot rely on the aid of mechanical shearing force. Therefore, it often requires a relatively large amount of power to cut tissue. However, this relatively large amount of power results in relatively large thermal damage to the tissue.

[0008] The advantage of bipolar output is that when coagulating tissue, the tissue to be coagulated is sandwiched between the two poles of the bipolar, so the power is concentrated on the tissue between the two poles. Bipolar scissors (also known as bipolar tweezers or bipolar pliers) have a better coagulation effect than monopolar electrosurgical pens, and due to the mechanical structure characteristics of the bipolar, they also have a shear force when cutting that monopolar electrosurgical pens do not have.

[0009] However, the energy output of bipolar instruments (bipolar scissors, bipolar tweezers, bipolar pliers) themselves is generally smaller than that of monopolar instruments, and the tissue energy density between the upper and lower blades is smaller than the tissue energy density at the tip of a monopolar electrosurgical pen, making it difficult to achieve rapid vaporization and separation of the tissue when cutting relatively thick tissue. Therefore, bipolar instruments (bipolar scissors, bipolar tweezers, bipolar pliers) are often only able to cut thin tissue. In short, the monopolar output mode favors cutting and is unfavorable to coagulation, while the bipolar output mode favors coagulation and is unfavorable to cutting. Summary of the Invention [Problem to be solved by the invention]

[0010] A primary object of the present invention is to provide a monopolar-bipolar hybrid output method that can achieve monopolar-bipolar hybrid output with the same actuator device. Another object of the present invention is to provide a surgical operating system that can achieve monopolar and bipolar hybrid outputs with the same actuator instrument. [Means for solving the problem]

[0011] In order to achieve the above-mentioned main object, the present invention provides a monopolar-bipolar hybrid output method, which is applied to a surgical operating system, and includes determining an output mode selection command by an operator, and when a command to select the monopolar-bipolar hybrid mode is obtained, controlling a first actuator instrument to perform a cutting operation and a tissue coagulation operation.

[0012] In a further solution, when performing a cutting operation in the monopolar-bipolar hybrid mode, the main control unit controls the first set of control signals to cause current to pass through the first actuator end of the first actuator instrument, and then through the human tissue to reach the circuit electrode, thereby forming a first current circuit, and causing the first actuator instrument to complete the cutting operation in the monopolar-bipolar hybrid mode.

[0013] In a further solution, when performing a tissue coagulation operation in monopolar-bipolar hybrid mode, the main control unit uses a second set of control signals to cause current to pass through the first actuator end of the first actuator instrument, pass through the tissue to be ablated, and reach the second actuator end of the first actuator instrument, forming a second current circuit and completing the tissue coagulation operation in monopolar-bipolar hybrid mode with the first actuator instrument.

[0014] In a further embodiment, the output mode further includes a monopolar mode, in which the main control unit controls the third set of control signals to cause current to pass through the third actuator end of the second actuator instrument, and then through the human tissue to reach the circuit electrode, thereby forming a third current circuit, and causing the second actuator instrument to complete the cutting and tissue coagulation operations in the monopolar mode. In a further embodiment, the output mode further includes a bipolar mode, in which the main control unit controls, according to a fourth set of control signals, the current to pass through the first actuator end of the first actuator instrument, and then through the human tissue to reach the second actuator end of the first actuator instrument, thereby forming a fourth current circuit, and causing the first actuator instrument to complete the cutting and tissue coagulation operations in the bipolar mode.

[0015] In order to achieve the above-mentioned other object, the surgical operating system according to the present invention includes a main control unit, a control panel (1), and an actuator instrument. The main control unit includes a central controller (2), a high-frequency power supply module (3), and a switch matrix (4). The high-frequency power supply module (3) is connected to the central controller (2) and the switch matrix (4), respectively. The central controller (2) receives a selection command output from the control panel (1) and reads mode information or pedal switch commands from a chip built into the actuator instrument. The central controller (2) outputs a switch drive signal to the switch matrix (4), controlling the switch matrix (4) to turn on and drive the actuator instrument.

[0016] In a further embodiment, the switch matrix includes a first switch transistor (41), a second switch transistor (42), a third switch transistor (43), and a fourth switch transistor (44), and the central controller (2) sends switch driving signals to the first switch transistor (41), the second switch transistor (42), the third switch transistor (43), and the fourth switch transistor (44) based on the received selection command, thereby controlling the on / off of the first switch transistor (41), the second switch transistor (42), the third switch transistor (43), and the fourth switch transistor (44). In a further embodiment, the switch matrix (4) further includes a sixth switch transistor and a seventh switch transistor, and the central controller (2) sends switch driving signals to the sixth switch transistor and the seventh switch transistor based on the received selection command to control the on / off of the sixth switch transistor and the seventh switch transistor.

[0017] In a further embodiment, the actuator device comprises a first actuator device, a second actuator device and a circuit electrode (5), a first output socket (21) of the switch matrix (4) is connected to an end of the first actuator device, and a second output socket (22) of the switch matrix (4) is connected to an end of the second actuator device and an end of the circuit electrode (5), respectively, wherein the first actuator device is a bipolar device (7) and the second actuator device is an electrode structure (6). In a further embodiment, the bipolar instrument (7) comprises a first conductive region (73), a second conductive region (74), a handle assembly (75), and an actuator end of the bipolar instrument, the first conductive region (73) being connected to a first output end of the first outlet (21), the second conductive region (74) being connected to a second output end of the first outlet (21), and the handle assembly (75) being connected to the actuator end of the bipolar instrument, wherein the actuator end of the bipolar instrument has a first actuator end (71) and a second actuator end (72), and the electrode structure (6) has a third actuator end. [Effects of the Invention]

[0018] The beneficial effects of the present invention are as follows: The same actuator instrument in the present application can be used in a monopolar-bipolar hybrid output mode, and in the monopolar-bipolar hybrid output mode, the same actuator instrument can achieve a hybrid mode of cutting in monopolar mode and hemostasis in bipolar mode, overcoming the drawbacks of the conventional monopolar output and the conventional bipolar output, and integrating the advantages of the monopolar output and the bipolar output. In the monopolar-bipolar hybrid output mode, the bipolar instrument can achieve cutting using the monopolar mode, whereby one actuator end of the bipolar instrument can have a relatively high energy density, and with the help of the cutting force of the bipolar instrument, the bipolar instrument can achieve the cutting function with low power, thereby significantly reducing the damage caused to the patient during surgery. In the monopolar-bipolar hybrid output mode, coagulation by a bipolar instrument is essentially still bipolar coagulation, and the advantage of bipolar coagulation compared to the coagulation effect of monopolar mode is that at a certain depth of the coagulation site, the power is more concentrated and the coagulation layer is deeper, thereby achieving a greater hemostatic effect on the bleeding site. The present invention simultaneously has the above three operation modes, and the output mode can be arbitrarily switched according to the needs of surgery through cooperation of the actuator instrument.

Here, the switch matrix 4 further includes a sixth switch transistor and a seventh switch transistor, and the central controller 2 sends switch drive signals to the sixth switch transistor and the seventh switch transistor based on the received selection command to control the on / off of the sixth switch transistor and the seventh switch transistor.

[0023] The switch matrix 4 of this embodiment is preferably a relay switch matrix, but is not limited to relays and may be a photocoupler, a triode, a power MOSFET, an insulated gate bipolar transistor (IGBT), or any other controllable switch.

[0024] 5, the first switch transistor 41, the second switch transistor 42, the third switch transistor 43, the fourth switch transistor 44, the sixth switch transistor, and the seventh switch transistor are the first relay switch JDQ1, the second relay switch JDQ2, the third relay switch JDQ3, the fourth relay switch JDQ4, the sixth relay switch JDQ6, and the seventh relay switch JDQ7, respectively, and the central controller 2 turns on six signals of the relay switches via the same type of inverter (e.g., 74HC14D, etc.), which are the CH1_PK2ABDR signal of the input field-effect transistor G5, the CH1_PKABDR signal of the field-effect transistor G1, the CH2_PKADR signal of the field-effect transistor G4, the CH3_BEMDR signal of the field-effect transistor G2, the CH4_VP2DR signal of the field-effect transistor G6, and the CH4_VPDR signal of the field-effect transistor G3, respectively.

[0025] Of course, the field effect transistor in this embodiment can be a photocoupler, such as PC817, an analog switch, such as 74HC4066, or a triode, etc., to complete the switch control for the relay.

[0026] Specifically, the central controller 2 outputs a CH1_PK2ABDR signal to the gate electrode of the field effect transistor G5, the drain electrode of which is connected to the third terminal of the first relay switch JDQ1; the central controller 2 outputs a CH1_PKABDR signal to the gate electrode of the field effect transistor G1, the drain electrode of which is connected to the third terminal of the second relay switch JDQ2; the central controller 2 outputs a CH2_PKADR signal to the gate electrode of the field effect transistor G4, the drain electrode of which is connected to the third terminal of the third relay switch JDQ3. the drain electrode of the field effect transistor G6 is connected to the third terminal of the sixth relay switch JDQ6; the central controller 2 outputs a CH4_VP2DR signal to the gate electrode of the field effect transistor G3, the drain electrode of which is connected to the third terminal of the seventh relay switch JDQ7; the central controller 2 outputs a CH3_BEMDR signal to the gate electrode of the field effect transistor G2, the drain electrode of which is connected to the third terminal of the seventh relay switch JDQ7; the central controller 2 outputs a CH4_VP2DR signal to the gate electrode of the field effect transistor G6, the drain electrode of which is connected to the third terminal of the seventh relay switch JDQ7. The source electrodes of field effect transistor G1, field effect transistor G2, field effect transistor G3, field effect transistor G4, field effect transistor G5, field effect transistor G6, and field effect transistor G7 are each grounded, a first end of the first relay switch JDQ1 is connected to node 1, which is connected to node 3, a first end of the third relay switch JDQ3 and a first end of the sixth relay switch JDQ6 are connected to node 3, a first end of the second relay switch JDQ2, a first end of the fourth relay switch JDQ4, and a first end of the seventh relay switch JDQ7 are connected to node 2.The second terminal of the first relay switch JDQ1 and the second terminal of the second relay switch JDQ2 are connected to the first output outlet 21 (e.g., SM output base), the second terminal of the sixth relay switch JDQ6 and the second terminal of the seventh relay switch JDQ7 are connected to the third output outlet (e.g., VP output base), and the second terminal of the third relay switch JDQ3 and the second terminal of the fourth relay switch JDQ4 are connected to the second output outlet 22 (e.g., J_MONO and J_PATIENT). In this embodiment, the actuator device includes a first actuator device, a second actuator device, and a circuit electrode 5, a first output outlet 21 of the switch matrix 4 is connected to an end of the first actuator device, and a second output outlet 22 of the switch matrix 4 is connected to an end of the second actuator device and an end of the circuit electrode 5, respectively, where the first actuator device is a bipolar device 7, the second actuator device is an electrode structure 6, and the circuit electrode 5 is a negative electrode plate (bottom plate). The second output outlet 22 of this embodiment may be electrically divided into two interface outlets, i.e., one interface outlet is connected to the 3-port of the second output outlet 22, and another interface outlet is connected to the 4-port of the second output outlet 22, one interface outlet is connected to the second actuator device, and the other interface outlet is connected to the circuit electrode 5.

[0027] 6, bipolar instrument 7 includes a first conductive region 73, a second conductive region 74, a handle assembly 75, and an actuator end of the bipolar instrument, with first conductive region 73 connected to a first output end of first outlet 21 and second conductive region 74 connected to a second output end of first outlet 21 (the reverse connection is also possible), and handle assembly 75 connected to the actuator end of the bipolar instrument. Bipolar instrument 7 in this embodiment is preferably bipolar electrocoagulation scissors, but is not limited to bipolar electrocoagulation scissors and may be other bipolar electrocoagulation instruments such as bipolar electrocoagulation pliers or bipolar electrocoagulation tweezers. Electrode structure 6 in this embodiment is preferably a monopolar electrosurgical pen module or a similar structure. The actuator end of the bipolar instrument has a first actuator end 71 and a second actuator end 72, the electrode structure 6 has a third actuator end, and the first conductive region is electrically connected to the first actuator end of the bipolar actuator instrument and the second conductive region is electrically connected to the second actuator end of the bipolar actuator instrument, or the first conductive region is electrically connected to the second actuator end and the second conductive region is electrically connected to the first actuator end. Here, the first actuator end 71 of the bipolar instrument 7 is the upper blade end, the second actuator end 72 of the bipolar instrument 7 is the lower blade end, and the third actuator end of the electrode structure 6 is the blade tip.

[0028] The high frequency power supply module 3 of this embodiment has three energy output modes, which correspond to the three output modes of the surgical operating system of the present invention, namely, monopolar output mode, bipolar output mode, and monopolar-bipolar hybrid output mode. The main control unit can operate the operating system in monopolar output mode, bipolar output mode, or monopolar / bipolar hybrid output mode, so that when the monopolar-bipolar hybrid output mode of the system is selected, the same actuator instrument of the operating system can achieve monopolar-bipolar hybrid output.

[0029] When the monopolar-bipolar hybrid output mode is selected, during cutting, current passes through the blade ends of the bipolar instrument 7, passes through the human tissue, and flows into the negative electrode plate (essentially monopolar cutting), and during coagulation, current passes through the upper blade ends of the bipolar instrument 7, passes through the human tissue sandwiched between the bipolar instruments 7, and flows into the lower blade end of the bipolar instrument 7 (essentially bipolar coagulation). As can be seen, the same actuator instrument can achieve both monopolar-bipolar hybrid output (monopolar cutting, bipolar coagulation) and bipolar output (bipolar cutting, bipolar coagulation). Specifically, the monopolar energy output mode is used when using the bipolar instrument 7 to cut tissue. At this time, energy is output only from the upper blade end of the bipolar instrument 7, and the current passes through the tissue to reach the negative electrode plate. When using the bipolar instrument 7 to coagulate tissue, the bipolar energy output mode is used. The current flows through the upper and lower blade ends of the bipolar instrument 7 but does not pass through the negative electrode plate. In other words, the same actuator instrument (bipolar instrument 7) not only combines the advantages of the two energy output modes, monopolar and bipolar, but also overcomes the inherent disadvantages of each of the two energy output modes. In the monopolar mode, the circuit electrode 5 is electrically connected to the first output end (wire 4 or wire 3) of the second output outlet 22, and the electrode structure 6 is electrically connected to the second output outlet 22 (wire 3 or wire 4). When the monopolar mode is selected, the system turns on the third switch transistor 43 or the fourth switch transistor 44 to form a monopolar circuit and complete monopolar cutting and coagulation.

[0030] In bipolar mode, the bipolar instrument 7 is connected to the first output outlet 21 (bipolar output outlet), and when the bipolar mode is selected, the system turns on the first switch transistor 41 or the second switch transistor 42 to form a bipolar circuit and complete bipolar cutting and coagulation.

[0031] When the monopolar bipolar hybrid output mode is selected, the bipolar instrument 7 is connected to the first output outlet 21 and the circuit electrode 5 is connected to the second output outlet 22 . When the cutting pedal is enabled or the cutting button is manually controlled, the system turns on the first switch transistor 41 and the fourth switch transistor 44 connected to the circuit electrode 5, and turns off the second switch transistor 42 and the third switch transistor 43, allowing the current to pass through the actuator end (blade end) of the bipolar instrument 7, pass through the human tissue, and reach the circuit electrode 5 to form a current circuit, forming an essentially monopolar circuit, and completing monopolar cutting with the bipolar instrument 7. When the coagulation pedal is enabled or the coagulation button is manually controlled, the system turns on the first switch transistor 41, the second switch transistor 42, turns off the fourth switch transistor 44 connected to the circuit electrode 5, and turns off the third switch transistor 43 connected to the electrode structure 6, allowing the current to pass through one actuator end (e.g., the upper blade end) of the bipolar instrument 7, pass through the human tissue, and reach another actuator end (e.g., the lower blade end) of the bipolar instrument 7 to form a circuit, thereby forming an essential bipolar coagulation circuit and realizing the bipolar coagulation effect. In this embodiment, the high frequency power supply module 3 further has a fourth energy output mode, which corresponds to the bipolar VP mode, which is the fourth output mode of the surgical operating system of the present invention. The bipolar VP mode of the present invention is a second bipolar mode output or two or more bipolar mode outputs, and its output principle is the same as that of the bipolar mode, that is, a sixth switch transistor and a seventh switch transistor are added, and a corresponding bipolar device 7 is added to the corresponding output base. Preferably, the control panel 1 of this embodiment may be a touch display, but is not limited to a touch display, and may be a metal dome or any inductive display device that can receive input signals such as contacts.

[0032] Specifically, the central controller 2 controls the radio frequency power supply module 3 via an interface and a radio frequency adapter (e.g., a J_RF1 outlet), and the radio frequency power supply module 3 outputs to the patient via a J_RF outlet and a relay switch matrix. The communication method between the central controller 2 and the radio frequency power supply module 3 may be a serial data format or a parallel data format. The serial data format may be SPI, IIC, UART, a single-wire bus, etc., and the parallel data format may be an asynchronous clock such as 8 bits, 16 bits, or 32 bits, or a synchronous clock such as 8 bits, 16 bits, or 32 bits. Example of a monopolar-bipolar hybrid output method for a surgical operating system: Referring to FIG. 7, the monopolar / bipolar hybrid output method of the present invention is applied to an electrosurgical operating system, and the method includes determining a selection command for monopolar mode, bipolar mode, or monopolar / bipolar hybrid mode by a control panel 1, the selection command being given by an operator or given from mode information read by a chip built into an actuator instrument, and when the main control unit obtains a command to select the monopolar / bipolar hybrid mode, controlling a first actuator instrument to perform cutting and tissue coagulation operations. Specifically, the operating system communicates with the central controller 2 through the touch display. After the system is started, the touch display enters a standby screen for mode selection, with the right area being the monopolar area and the left area being the bipolar mode area, where the upper left area is the bipolar SM area and the lower left area is the bipolar VP control area. In actual application, there are two mode selection buttons in the upper left bipolar SM area. First mode selection button: When the first bipolar mode is pressed, the bipolar output mode is activated. That is, the relay is selected to allow current to pass through one actuator end of the bipolar instrument 7, then through the human tissue sandwiched between the bipolar electrodes, and then into the other actuator end of the bipolar instrument 7. Second mode selection button: When the second bipolar mode is pressed, the monopolar-bipolar hybrid mode is activated. When the system detects that the circuit electrode 5 is already connected to the patient, the system selects the relay to allow current to pass through the actuator end of the bipolar instrument 7, then through the human tissue, and then into the circuit electrode 5 (essentially, monopolar cutting). During coagulation, the current passes through one actuator end of the bipolar instrument 7, then through the human tissue sandwiched between the bipolar electrodes, and then into the other actuator end of the bipolar instrument 7 (essentially, bipolar coagulation). In this embodiment, the system can read the electrode information via the bus, and based on the electrode information read thereby, determines whether the default output mode by the electrode is bipolar output or monopolar bipolar hybrid output.

[0033] When performing a cutting operation in the monopolar-bipolar hybrid mode, the main control unit uses a first set of control signals to cause the current to pass through the first actuator end 71 of the first actuator instrument, and then pass through the human tissue to reach the circuit electrode 5, thereby forming a first current circuit and allowing the first actuator instrument to complete the monopolar cutting operation in the monopolar-bipolar hybrid mode. In this embodiment, when performing a tissue coagulation operation in the monopolar-bipolar hybrid mode, the main control unit uses the second set of control signals to cause the current to pass through the first actuator end 71 of the first actuator instrument, then pass through the tissue to be ablated and reach the second actuator end 72 of the first actuator instrument, thereby forming a second current circuit and completing the bipolar tissue coagulation operation in the monopolar-bipolar hybrid mode with the first actuator instrument. In the monopolar mode, the main control unit uses the third set of control signals to cause the current to pass through the third actuator end of the second actuator instrument, and then pass through the human tissue to reach the circuit electrode 5, thereby forming a third current circuit, and completing the cutting and tissue coagulation operations in the monopolar mode with the second actuator instrument. In bipolar mode, the main control unit uses a fourth set of control signals to cause the current to pass through the first actuator end 71 of the first actuator instrument, then pass through the human tissue and reach the second actuator end 72 of the first actuator instrument, thereby forming a fourth current circuit and completing the cutting and tissue coagulation operations in bipolar mode with the first actuator instrument. Of course, the first set of control signals, the second set of control signals, the third set of control signals, and the fourth set of control signals in this embodiment are all output by the central controller 2 by controlling the high frequency power supply module 3 and the relay matrix, and form various current circuits. When using the monopolar mode, the electrode structure 6 (e.g., the cutting button of the electric scalpel pen) or the coagulation button is pressed, triggering the circuit to transmit the photocoupler signal of the photocoupler or the amplified electrical signal of the operational amplifier to the central controller 2. The central controller 2 then drives the relay switch signals CH2_PKADR and CH3_BEMDR via the same inverter to turn on the fourth switch transistor 44 (e.g., the fourth relay switch JDQ4) and the third switch transistor 43 (e.g., the third relay switch JDQ3). The central controller 2 then controls the remaining relays to turn off, causing the high-frequency power supply module 3 to output a high-frequency current. This high-frequency current passes through the third switch transistor 43 (e.g., the third relay switch JDQ3) to reach the electrode structure 6 (e.g., the electric scalpel pen), then passes through the human tissue to reach the circuit electrode 5, and then returns to the high-frequency power supply module 3 via the fourth switch transistor 44 (e.g., the fourth relay switch JDQ4), thereby achieving monopolar cutting and coagulation.

[0034] When using the bipolar mode, step on the pedal or manually control the cutting button or manually control the coagulation button, and the circuit triggers a signal to the central controller 2 via the data transmission interface. The central controller 2 turns on the relay switch signals CH1_PK2ABDR and CH1_PKABDR via the same inverter, turning on the first switch transistor 41 (e.g., the first relay switch JDQ1) and the second switch transistor 42 (e.g., the second relay switch JDQ2). The central controller 2 controls the remaining relays to be turned off. The high-frequency current passes through the first switch transistor 41 (e.g., the first relay switch JDQ1) to reach one actuator end of the bipolar instrument 7, then passes through the diseased tissue sandwiched between the bipolar instrument 7 to reach another actuator end of the bipolar instrument 7, and then returns from the other actuator end of the bipolar instrument 7 to the high-frequency power supply module 3 via the second switch transistor 42 (e.g., the second relay switch JDQ2), thereby realizing bipolar cutting and coagulation. As can be seen, the actuator instruments according to the present invention (eg, bipolar electrocoagulation scissors, pliers, tweezers) have better clinical effects than conventional bipolar actuator instruments.

[0035] When using the monopolar-bipolar hybrid mode, when performing cutting, the pedal is pressed or the cutting button is manually controlled, and a signal is transmitted to the central controller 2 via the data transmission interface by the circuit trigger. The central controller 2 then drives the relay switch signals CH1_PK2ABDR and CH3_BEMDR via the same inverter to turn on, turning on the first switch transistor 41 and the fourth switch transistor 44, and the central controller 2 controls the remaining switch transistors to turn off. The high-frequency current passes through the first switch transistor 41 to reach the actuator end of the bipolar instrument 7, then through the human tissue to reach the circuit electrode 5, and then returns to the high-frequency power supply module 3 via the fourth switch transistor 44, thereby realizing the monopolar cutting operation. When performing the tissue coagulation operation, the pedal is pressed or the coagulation button is manually controlled, and a signal is transmitted to the central controller 2 via the data transmission interface by the circuit trigger. The central controller 2 then drives the relay switch signals CH1_PK2ABDR and CH1_PKABDR via the same inverter to turn on, turning on the first switch transistor 41 and the second switch transistor 42, and the central controller 2 controls the remaining relays to turn off. The high-frequency current passes through the first switch transistor 41 to reach one actuator end of the bipolar instrument 7, then passes through the diseased tissue sandwiched between the bipolar instrument 7 to reach another actuator end of the bipolar instrument 7, and then returns from this other actuator end of the bipolar instrument 7 to the high-frequency power supply module 3 via the second switch transistor 42, thereby realizing the bipolar coagulation operation. The system further includes a bipolar VP mode output. This mode can be selected, for example, through the bipolar VP control area on the touch display, or by switching between the SM port output and the VP port output using the center switch on the pedal switch. The bipolar VP mode can be a second bipolar mode output or two or more bipolar mode outputs. That is, a sixth switch transistor and a seventh switch transistor are added, and corresponding bipolar electrocoagulation devices are added to the corresponding output bases. In the bipolar VP mode, the central controller 2 drives the relay switch signals through the same inverter to turn on the sixth switch transistor and the seventh switch transistor (e.g., the sixth relay switch JDQ6 and the seventh relay switch JDQ7), and the central controller 2 controls the remaining relays to turn off. The principle is the same as in the bipolar mode, except that by simply adding one or more radio frequency output bases (e.g., a third output base), different radio frequency output bases can be output. When an additional radio frequency output base is added, a bipolar electrocoagulation device can be added accordingly.

[0036] The beneficial effects of the present invention are as follows: The same actuator instrument in the present application can be used in a monopolar-bipolar hybrid output mode, and in the monopolar-bipolar hybrid output mode, the same actuator instrument can achieve a hybrid mode of cutting in monopolar mode and hemostasis in bipolar mode, overcoming the drawbacks of the conventional monopolar output and the conventional bipolar output, and integrating the advantages of the monopolar output and the bipolar output. In the monopolar-bipolar hybrid output mode, the bipolar instrument 7 can achieve cutting using the monopolar mode, so that one actuator end of the bipolar instrument 7 can have a relatively high energy density, and with the help of the cutting force of the bipolar instrument 7, the bipolar instrument 7 can achieve the cutting function with low power, thereby significantly reducing the damage caused to the patient during surgery. In the monopolar-bipolar hybrid output mode, the coagulation by the bipolar instrument 7 is still essentially bipolar coagulation, and the advantage of bipolar coagulation compared to the coagulation effect of the monopolar mode is that at a certain depth of the coagulation site, the power is more concentrated and the coagulation layer is deeper, thereby achieving a higher hemostatic effect on the bleeding site.

[0037] The present invention simultaneously has the above three operation modes, and the output mode can be arbitrarily switched according to the needs of surgery through cooperation of the actuator instrument.

[0038] It should be noted that the above is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any non-essential modifications made to the present invention using this concept are included within the protection scope of the present invention.
