Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electrosurgery, and in particular to a surgical operating system and a unipolar and bipolar mixed output method applied to the system. Background Art
[0002] Electrocautery utilizes the energy output by an electrosurgery system to cut and coagulate human tissue. The thermal effect of the current vaporizes tissue, which is the principle of cutting; the thermal effect of the current denatures and coagulates tissue proteins, which is the principle of coagulation.
[0003] Currently, electrosurgical systems generally have monopolar output functions and bipolar output functions.
[0004] In the prior art, Figure 1 As shown, Figure 1 This is an existing working mode of the monopolar output function of an electrosurgical system. The electrosurgical system includes a high-frequency power supply module, an electric knife pen, a loop electrode, an active wire and a loop electrode wire. The specific working process of the monopolar output function of the electrosurgical system is: the current flows from the electric knife pen through the human tissue into the negative plate attached to the patient to form a loop.
[0005] like Figure 2 As shown, Figure 2 This is a working mode of the bipolar output function of an existing electrosurgical system. The electrosurgical system includes bipolar scissors, active wires and loop electrode wires. The specific working process of the bipolar output function of the electrosurgical system is: the bipolar instrument clamps the tissue between the bipolar scissors (or bipolar forceps, bipolar clamps), and the current flows through the human tissue to complete tissue vaporization and coagulation to stop bleeding.
[0006] Therefore, existing electrosurgical systems generally have both monopolar and bipolar output functions. The advantages and disadvantages of monopolar output are as follows: Monopolar electrosurgeries using monopolar output mode have better cutting effects than bipolar electrosurgeries because the monopolar tip has a greater energy density.
[0007] However, because the electrosurgical pen is only one pole in the entire current loop, the electrical power cannot be concentrated to a large extent on the tissue to be coagulated. Instead, it passes through the pen tip and through a large area of human tissue to reach the negative electrode. Therefore, its coagulation effect is worse than that of a bipolar electrosurgical pen. Moreover, a monopolar electrosurgical pen cannot penetrate deep into the abdominal cavity for minimally invasive laparoscopic surgery. A monopolar electrosurgical pen cannot use mechanical shear force when cutting, so it often requires a higher power to cut tissue, but this higher power also causes greater tissue thermal damage.
[0008] Advantages and disadvantages of bipolar output: Because the tissue to be coagulated is sandwiched between the two bipolar poles, the electrical power is concentrated to a greater extent in the tissue between the two poles. Bipolar scissors (or bipolar forceps) have a better coagulation effect than monopolar electrosurgical pencils, and the mechanical structure of the bipolar structure allows them to have a shear force during cutting that monopolar electrosurgical pencils do not have.
[0009] However, because bipolar instruments (bipolar scissors or bipolar forceps) generally have lower energy output than monopolar instruments, and the tissue energy density between the upper and lower blades is lower than that at the tip of a monopolar electrosurgical unit, rapid vaporization and separation of tissue is difficult to achieve when cutting thick tissue. Therefore, bipolar instruments (bipolar scissors or bipolar forceps) are often only able to cut thin tissue.
[0010] In summary, the unipolar output mode is more conducive to cutting but not to coagulation; the bipolar output mode is more conducive to coagulation but not to cutting. Summary of the Invention
[0011] The main purpose of the present invention is to provide a method for achieving unipolar and bipolar mixed output on the same actuator.
[0012] Another object of the present invention is to provide a surgical operating system that can achieve monopolar and bipolar mixed output on the same execution instrument.
[0013] In order to achieve the above-mentioned main purpose, the present invention provides a monopolar and bipolar mixed output method, which is applied to a surgical operating system. The method includes: determining the operator's selection instruction for the output mode, and when the instruction to select the monopolar and bipolar mixed mode is obtained, controlling the first execution instrument to perform cutting and tissue coagulation actions.
[0014] In a further solution, in the monopolar and bipolar mixed mode, when performing a cutting action, the main control unit uses a first set of control signals to make the current pass through the first execution end of the first execution instrument through the human tissue to reach the loop electrode to form a first current loop, and complete the cutting action in the monopolar and bipolar mixed mode on the first execution instrument.
[0015] In a further solution, in the monopolar and bipolar mixed mode, when performing tissue coagulation action, the main control unit uses a second set of control signals to make the current pass through the first execution end of the first execution instrument through the tissue to be removed to reach the second execution end of the first execution instrument to form a second current loop, and complete the tissue coagulation action in the monopolar and bipolar mixed mode on the first execution instrument.
[0016] In a further solution, the output mode also includes a monopolar mode. In the monopolar mode, the main control unit uses a third set of control signals to make the current pass through the third execution end of the second execution instrument through the human tissue to reach the loop electrode to form a third current loop, and complete the cutting action and tissue coagulation action in the monopolar mode on the second execution instrument.
[0017] In a further solution, the output mode also includes a bipolar mode. In the bipolar mode, the main control unit uses a fourth set of control signals to make the current pass through the first execution end of the first execution instrument through the human tissue to reach the second execution end of the first execution instrument to form a fourth current loop, and complete the cutting action and tissue coagulation action in the bipolar mode on the first execution instrument.
[0018] In order to achieve the other purpose mentioned above, the present invention provides a surgical operating system, including: a main control unit, a control panel and an execution instrument, the main control unit includes a central controller, a high-frequency power supply module and a switch matrix, the high-frequency power supply module is connected to the central controller and the switch matrix respectively, the central controller receives the control panel output selection instruction, and reads the mode information or foot switch instruction of the built-in chip of the execution instrument, and the central controller outputs a driving switch signal to the switch matrix to control the switch matrix to turn on and drive the execution instrument.
[0019] A further solution is that the switch matrix includes a first switch tube, a second switch tube, a third switch tube, and a fourth switch tube, and the central controller sends a driving switch signal to the first switch tube, the second switch tube, the third switch tube, and the fourth switch tube according to the received selection instruction to control the conduction and shutdown of the first switch tube, the second switch tube, the third switch tube, and the fourth switch tube.
[0020] A further solution is that the switch matrix also includes a sixth switch tube and a seventh switch tube, and the central controller sends a driving switch signal to the sixth switch tube and the seventh switch tube according to the received selection instruction to control the conduction and shutdown of the sixth switch tube and the seventh switch tube.
[0021] A further solution is that the execution instrument includes a first execution instrument, a second execution instrument and a loop electrode, the first output socket of the switch matrix is connected to the end of the first execution instrument, and the second output socket of the switch matrix is connected to the end of the second execution instrument and the end of the loop electrode, respectively, wherein the first execution instrument is a bipolar instrument and the second execution instrument is an electrode structure.
[0022] A further solution is that the bipolar instrument includes a first conductive area, a second conductive area, a handle assembly and a bipolar instrument execution end, the first conductive area is connected to the first output end of the first output socket, the second conductive area is connected to the second output end of the first output socket, and the handle assembly is connected to the bipolar instrument execution end, wherein the bipolar instrument execution end has a first execution end and a second execution end, and the electrode structure has a third execution end.
[0023] The beneficial effects of the present invention are: the present application can be used in a monopolar and bipolar mixed output mode in the same execution instrument. In the monopolar and bipolar mixed output mode, the same execution instrument can realize a mixed mode of monopolar mode cutting and bipolar mode hemostasis, overcoming the respective shortcomings of conventional monopolar output and conventional bipolar output, and integrating the respective advantages of monopolar output and bipolar output.
[0024] In the monopolar and bipolar mixed output mode, the bipolar instrument can be used for cutting using the monopolar mode, so that one of the execution ends of the bipolar instrument can also have a higher energy density; and with the help of the cutting force of the bipolar instrument, the bipolar instrument can complete the cutting function at low power, thereby greatly reducing the damage caused to the patient during the operation.
[0025] In the mixed monopolar and bipolar output mode, the coagulation nature of the bipolar device is still bipolar coagulation. Compared with the coagulation effect of the monopolar mode, the advantage of bipolar coagulation is that the power is more concentrated within a certain depth of the coagulation site, and the coagulation layer is thicker, thereby having a better hemostatic effect on the bleeding point.
[0026] In addition, the present invention has the above three working modes at the same time, and the output mode can be switched arbitrarily according to surgical needs with the cooperation of the executing instrument. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A surgical operating system embodiment:
[0036] See also Figures 3 and 4 The surgical operating system of the present invention comprises a main control unit consisting of a central controller 2, a high-frequency power module 3, and a switch matrix 4; a control panel 1; and an actuator. The high-frequency power module 3 is connected to the central controller 2 and switch matrix 4, respectively. The central controller 2 receives selection instructions from the control panel 1 and reads mode information or footswitch instructions from the actuator's built-in chip. The central controller 2 outputs a drive switch signal to the switch matrix 4 to control the switch matrix 4 to conduct and drive the actuator. The selection instruction in this embodiment can be a command selected by the user through the display interface of the control panel 1, or it can be instruction information recognized by the system through the electrode's built-in chip.
[0037] Among them, the central controller 2 of this embodiment can be a chip with computing functions such as MCU, but is not limited to MCU. It can also refer to other microcontrollers such as DSP, microcomputer, programmable logic controller CPLD, FPGA, application-specific integrated circuit and other programmable circuits.
[0038] In this embodiment, the surgical operating system further includes a low-voltage power supply 10 and a switching power supply 9. The low-voltage power supply 10 provides 5V / 12V power to the central controller 2, and the switching power supply 9 provides 48V power to the high-frequency power module 3. Of course, the low-voltage power supply 10 and the switching power supply 9 in this embodiment may have other voltage outputs, such as a 24V power output.
[0039] In this embodiment, the switch matrix 4 includes a first switch tube 41, a second switch tube 42, a third switch tube 43, a fourth switch tube 44, a first output socket 21, a second output socket 22, and at least one third output socket. The central controller 2 sends a driving switch signal to the first switch tube 41, the second switch tube 42, the third switch tube 43, and the fourth switch tube 44 according to the received selection instruction to control the conduction and shutdown of the first switch tube 41, the second switch tube 42, the third switch tube 43, and the fourth switch tube 44.
[0040] The switch matrix 4 further includes a sixth switch tube and a seventh switch tube. The central controller 2 sends a drive switch signal to the sixth switch tube and the seventh switch tube according to the received selection instruction to control the conduction and shutdown of the sixth switch tube and the seventh switch tube.
[0041] Furthermore, the first switch tube 41 and the second switch tube 42 are respectively connected to the first output end and the second output end of the first output socket 21, the third switch tube 43 and the fourth switch tube 44 are respectively connected to the first output end and the second output end of the second output socket 22, and the sixth switch tube and the seventh switch tube are respectively connected to the first output end and the second output end of the third output socket.
[0042] The switch matrix 4 of this embodiment is preferably a relay switch matrix, but is not limited to relays, and may also be a photocoupler, a transistor, a power MOSFET, an insulated gate bipolar transistor (IGBT) or any other controllable switch.
[0043] Specifically, such as Figure 5 As shown, the first switch tube 41, the second switch tube 42, the third switch tube 43, the fourth switch tube 44, the sixth switch tube, and the seventh switch tube are respectively 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. The central controller 2 conducts six signals to drive the relay switches through similar inverters (such as 74HC14D, etc.), which are respectively 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.
[0044] Of course, the field effect tube of this embodiment can also be a photocoupler, such as PC817; it can also be an analog switch, such as 74HC4066; it can also be a transistor to complete the switching control of the relay.
[0045] Specifically, the central controller 2 outputs the CH1_PK2ABDR signal to the gate of the field effect tube G5, the drain of the field effect tube G5 is connected to the third end of the first relay switch JDQ1, the central controller 2 outputs the CH1_PKABDR signal to the gate of the field effect tube G1, the drain of the field effect tube G1 is connected to the third end of the second relay switch JDQ2, the central controller 2 outputs the CH2_PKADR signal to the gate of the field effect tube G4, the drain of the field effect tube G4 is connected to the third end of the third relay switch JDQ3. The central controller 2 outputs a CH3_BEMDR signal to the gate of the field-effect transistor G2, the drain of which is connected to the third terminal of the fourth relay switch JDQ4. The central controller 2 outputs a CH4_VP2DR signal to the gate of the field-effect transistor G6, the drain of which is connected to the third terminal of the sixth relay switch JDQ6. The central controller 2 outputs a CH4_VPDR signal to the gate of the field-effect transistor G3, the drain of which is connected to the third terminal of the seventh relay switch JDQ7. The sources of the field-effect transistors G1, G2, G3, G4, G5, G6, and G7 are grounded, respectively. The first terminal of the first relay switch JDQ1 is connected to node 1, which is connected to node 3. The first terminal of the third relay switch JDQ3 and the first terminal of the sixth relay switch JDQ6 are connected to node 3. The first end of the second relay switch JDQ2, the first end of the fourth relay switch JDQ4, and the first end of the seventh relay switch JDQ7 are connected to node 2. The second end of the first relay switch JDQ1 and the second end of the second relay switch JDQ2 are connected to the first output socket 21 (e.g., the SM output socket), the second end of the sixth relay switch JDQ6 and the second end of the seventh relay switch JDQ7 are connected to the third output socket (e.g., the VP output socket), and the second end of the third relay switch JDQ3 and the second end of the fourth relay switch JDQ4 are connected to the second output socket 22 (e.g., J_MONO and J_PATIENT).
[0046] In this embodiment, the actuator includes a first actuator, a second actuator, and a return electrode 5. The first output socket 21 of the switch matrix 4 is connected to the end of the first actuator, and the second output socket 22 of the switch matrix 4 is connected to the end of the second actuator and the end of the return electrode 5, respectively. The first actuator is a bipolar instrument 7, the second actuator is an electrode structure 6, and the return electrode 5 is a negative electrode plate (muscle plate). The second output socket 22 of this embodiment can be electrically divided into two interface sockets, namely, one interface socket connected to port 3 of the second output socket 22, and the other interface socket connected to port 4 of the second output socket 22. One interface socket is connected to the second actuator, and the other interface socket is connected to the return electrode 5.
[0047] See also Figure 6The bipolar instrument 7 includes a first conductive region 73, a second conductive region 74, a handle assembly 75, and a bipolar instrument actuator. The first conductive region 73 is connected to the first output terminal of the first output socket 21, the second conductive region 74 is connected to the second output terminal of the first output socket 21 (or vice versa), and the handle assembly 75 is connected to the bipolar instrument actuator. The bipolar instrument 7 of this embodiment is preferably a bipolar coagulation shear, but is not limited to bipolar coagulation shears. It can also be a bipolar coagulation forceps, bipolar coagulation tweezers, or other bipolar coagulation devices. The electrode structure 6 of this embodiment is preferably a monopolar electrosurgical pen module or a similar structure.
[0048] The bipolar instrument's actuator end has a first actuator end 71 and a second actuator end 72, and the electrode structure 6 has a third actuator end. The first conductive region is electrically connected to the first actuator end of the bipolar instrument, and the second conductive region is electrically connected to the second actuator end of the bipolar instrument; alternatively, 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. 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 head end.
[0049] The high-frequency power module 3 of this embodiment has three energy output modes, corresponding to the three output modes of the surgical operating system of the present invention: monopolar mode, bipolar mode, or monopolar / bipolar mixed mode. The main control unit allows the operating system to operate in monopolar output mode, bipolar output mode, or monopolar / bipolar mixed output mode. When the system monopolar / bipolar mixed output mode is selected, the operating system can achieve monopolar and bipolar mixed output on the same operating instrument.
[0050] When the monopolar and bipolar hybrid mode is selected, during cutting, the current flows through the blade end of the bipolar instrument 7, through the human tissue, and into the negative electrode plate (essentially monopolar cutting). During coagulation, the current flows through the upper blade end of the bipolar instrument 7, through the human tissue sandwiched between the bipolar instruments 7, and into the lower blade end of the bipolar instrument 7 (essentially bipolar coagulation). Thus, both monopolar and bipolar hybrid output (monopolar cutting, bipolar coagulation) and bipolar output (bipolar cutting, bipolar coagulation) can be achieved on the same instrument.
[0051] Specifically, when using bipolar instrument 7 for tissue cutting, the unipolar energy output mode is used. In this case, energy is output only at the upper blade end of bipolar instrument 7, and current flows through the tissue to the negative plate. When using bipolar instrument 7 for tissue coagulation, the bipolar energy output mode is used. Current flows between the upper and lower blade ends of bipolar instrument 7, and current does not flow through the negative plate. In other words, the advantages of both unipolar and bipolar energy output modes are integrated into the same instrument (bipolar instrument 7), while overcoming the inherent disadvantages of both modes.
[0052] In monopolar mode, loop electrode 5 is electrically connected to the first output terminal (line 4 or line 3) of second output socket 22, and electrode structure 6 is electrically connected to second output socket 22 (line 3 or line 4). When monopolar mode is selected, the system closes third switch 43 or fourth switch 44 to form a monopolar loop, completing monopolar cutting and coagulation.
[0053] In bipolar mode, the bipolar instrument 7 is connected to the first output socket 21 (bipolar output socket). When the bipolar mode is selected, the system closes the first switch tube 41 or the second switch tube 42 to form a bipolar circuit to complete bipolar cutting and coagulation.
[0054] When the monopolar and bipolar mixed output mode is selected, the bipolar instrument 7 is connected to the first output socket 21 , and the return electrode 5 is connected to the second output socket 22 .
[0055] When the cutting pedal or manual cutting button is enabled, the system closes the first switch tube 41 and the fourth switch tube 44 connected to the loop electrode 5, and disconnects the second switch tube 42 and the third switch tube 43, so that the current passes through the execution end (blade end) of the bipolar instrument 7 through the human tissue to reach the loop electrode 5 to form a current loop, forming an essentially monopolar loop, and completing monopolar cutting on the bipolar instrument 7.
[0056] When the coagulation pedal is enabled or the manual coagulation button is pressed, the system closes the first switch tube 41 and the second switch tube 42, disconnects the fourth switch tube 44 connected to the loop electrode 5, and disconnects the third switch tube 43 connected to the electrode structure 6, so that the current passes through one execution end of the bipolar instrument 7 (such as the upper blade end) through the human tissue to reach the other execution end of the bipolar instrument 7 (such as the lower blade end) to form a loop, forming an essential bipolar coagulation circuit and achieving a bipolar coagulation effect.
[0057] In this embodiment, the high-frequency power supply module 3 also has a fourth energy output mode, corresponding to the fourth output mode of the surgical operating system of the present invention: bipolar VP mode.
[0058] The bipolar VP mode of the present invention is a second bipolar mode output or two or more bipolar mode outputs. Its output principle is the same as that of the bipolar mode, that is, a sixth switch tube and a seventh switch tube are added, and a corresponding bipolar device 7 is added to the corresponding output socket.
[0059] Preferably, the control panel 1 of this embodiment may be a touch screen display, but is not limited to a touch screen display. It may be a membrane keypad, or any inductive display device that can receive input signals such as contacts.
[0060] Specifically, the central controller 2 controls the high-frequency power module 3 via an interface and a radio frequency adapter (such as the J_RF1 socket). The high-frequency power module 3 then outputs power to the patient via the J_RF socket and relay switch matrix. The central controller 2 and the high-frequency power module 3 can communicate in either serial or parallel data formats. Serial data formats can include SPI, IIC, UART, or a 1-wire bus. Parallel data formats can include asynchronous clocks (8-bit, 16-bit, or 32-bit), or synchronous clocks (8-bit, 16-bit, or 32-bit).
[0061] An embodiment of a unipolar and bipolar mixed output method for a surgical operating system:
[0062] See also Figure 7 A monopolar and bipolar mixed output method of the present invention is applied to an electrosurgical operation system. The method includes: determining, through a control panel 1, a selection instruction for a monopolar mode, a bipolar mode, or a monopolar and bipolar mixed mode based on mode information read by an operator or a chip built into an execution instrument; when a main control unit obtains an instruction to select a monopolar and bipolar mixed mode, it controls the first execution instrument to perform a cutting action and a tissue coagulation action.
[0063] Specifically, the operating system interacts with the central controller 2 via the touch screen. Regarding mode selection: After the system is turned on, the touch screen enters the standby interface. The right area is the unipolar area, and the left area is the bipolar mode area. The upper left area is the bipolar SM area, and the lower left area is the bipolar VP control area.
[0064] In actual application, there are two mode selection buttons in the upper left bipolar SM area. The first mode selection button: when the first bipolar mode is pressed, it is a bipolar output mode, that is, the current passes through one execution end of the bipolar instrument 7 through the human tissue sandwiched between the bipolar poles and flows into the other execution end of the bipolar instrument 7; the second mode selection button: when the second bipolar mode is pressed, it is a monopolar and bipolar mixed mode. When the system detects that the loop electrode 5 has been connected to the patient, the system will select through the relay so that when cutting, the current passes through the execution end of the bipolar instrument 7 through the human tissue and flows into the loop electrode 5 (essentially monopolar cutting). When coagulation occurs, the current passes through one execution end of the bipolar instrument 7 through the human tissue sandwiched between the bipolar poles and flows into the other execution end of the bipolar instrument 7 (essentially bipolar coagulation).
[0065] In this embodiment, the system can read the electrode information through a one-line bus to confirm that the default output mode of the electrode is bipolar output or monopolar and bipolar mixed output.
[0066] In the monopolar and bipolar mixed mode, when performing a cutting action, the main control unit uses a first set of control signals to make the current pass through the first execution end 71 of the first execution instrument through the human tissue to reach the loop electrode 5 to form a first current loop, and complete the monopolar cutting action in the monopolar and bipolar mixed mode on the first execution instrument.
[0067] In this embodiment, in the monopolar and bipolar mixed mode, when performing tissue coagulation action, the main control unit uses a second set of control signals to make the current pass through the first execution end 71 of the first execution instrument through the tissue to be removed to reach the second execution end 72 of the first execution instrument to form a second current loop, and complete the bipolar tissue coagulation action in the monopolar and bipolar mixed mode on the first execution instrument.
[0068] In the monopolar mode, the main control unit uses a third set of control signals to make the current pass through the third execution end of the second execution instrument through the human tissue to reach the loop electrode 5 to form a third current loop, and complete the cutting action and tissue coagulation action in the monopolar mode on the second execution instrument.
[0069] In bipolar mode, the main control unit uses a fourth set of control signals to cause the current to pass through the first execution end 71 of the first execution instrument through the human tissue to reach the second execution end 72 of the first execution instrument to form a fourth current loop, and complete the cutting action and tissue coagulation action in bipolar mode on the first execution instrument.
[0070] Of course, the first, second, third and fourth control signals of this embodiment are all output by the central controller 2 to control the high-frequency power module 3 and the relay matrix, and form various current loops.
[0071] When using the monopolar mode, the electrode structure 6 (such as an electric knife pen for cutting) or the coagulation button is pressed, and the optocoupler signal or the amplified electrical signal of the optocoupler or op amp is triggered by the circuit and transmitted to the central controller 2. The central controller 2 drives the relay switch signals CH2_PKADR and CH3_BEMDR through the same type of inverter to turn on the fourth switch tube 44 (such as the fourth relay switch JDQ4) and the third switch tube 43 (such as the third relay switch JDQ3), and the central controller 2 controls the remaining relays to be disconnected, so that the high-frequency power supply module 3 outputs high-frequency current through the third switch tube 43 (such as the third relay switch JDQ3) to reach the electrode structure 6 (such as an electric knife pen) through the human tissue to reach the loop electrode 5, and returns to the high-frequency power supply module 3 via the fourth switch tube 44 (such as the fourth relay switch JDQ4), thereby realizing monopolar cutting and coagulation.
[0072] When using the bipolar mode, stepping on the foot pedal or manual cutting or coagulation button triggers the circuit and transmits it to the central controller 2 through the data transmission interface. The central controller 2 drives the relay switch signals CH1_PK2ABDR and CH1_PKABDR through the same type of inverter to turn on the first switch tube 41 (such as the first relay switch JDQ1) and the second switch tube 42 (such as the second relay switch JDQ2). The central controller 2 controls the remaining relays to be disconnected, so that the high-frequency current passes through the first switch tube 41 (such as the first relay switch JDQ1) to reach one execution end of the bipolar instrument 7, passes through the diseased tissue clamped by the bipolar instrument 7, and returns to the high-frequency power supply module 3 from the other execution end of the bipolar instrument 7 via the second switch tube 42 (such as the second relay switch JDQ2), thereby achieving bipolar cutting and coagulation. It can be seen that the execution instrument provided by the present invention (such as bipolar electrocoagulation scissors, forceps, and tweezers) has better clinical effects than conventional bipolar execution instruments.
[0073] When using the monopolar and bipolar mixed mode, when executing the cutting action, stepping on the foot pedal or the manual cutting button will trigger the circuit and transmit it to the central controller 2 through the data transmission interface. The central controller 2 drives the relay switch signals CH1_PK2ABDR and CH3_BEMDR through the same type of inverter to turn on the first switch tube 41 and the fourth switch tube 44, and the central controller 2 controls the remaining switch tubes to be disconnected, so that the high-frequency current passes through the first switch tube 41 to the execution end of the bipolar instrument 7, passes through the human tissue, reaches the loop electrode 5, and returns to the high-frequency power supply module 3 through the fourth switch tube 44, thereby realizing the monopolar cutting operation.
[0074] When performing tissue coagulation, step on the foot pedal or the manual coagulation button, which is triggered by the circuit and transmitted to the central controller 2. The central controller 2 drives the relay switch signals CH1_PK2ABDR and CH1_PKABDR through the same type of inverter to turn on the first switch tube 41 and the second switch tube 42, and the central controller 2 controls the remaining relays to be disconnected, so that the high-frequency current passes through the first switch tube 41 to reach one execution end of the bipolar instrument 7, passes through the diseased tissue clamped by the bipolar instrument 7, and returns to the high-frequency power supply module 3 from the other execution end of the bipolar instrument 7 via the second switch tube 42, thereby realizing the bipolar coagulation operation.
[0075] The system also includes a bipolar VP mode output, such as selecting the mode by touching the bipolar VP control area of the display screen, or switching the SM port output and the VP port output by the conversion button in the middle of the foot switch. The bipolar VP mode is a second bipolar mode output or two or more bipolar mode outputs, that is, adding a sixth switch tube and a seventh switch tube, and adding corresponding bipolar electrocoagulation instruments to the corresponding output sockets. In the bipolar VP mode, the central controller 2 drives the relay switch signal through the same type of inverter to turn on the sixth switch tube and the seventh switch tube (such as the sixth relay switch JDQ6 and the seventh relay switch JDQ7) to turn on, and the central controller 2 controls the remaining relays to disconnect. The principle is the same as the above-mentioned bipolar mode, except that one or more RF output socket outputs (such as the third output socket) are added to achieve different RF output socket outputs. When another RF output socket is added, the bipolar electrocoagulation instrument can be added accordingly.
[0076] The beneficial effects of the present invention are: the present application can be used in a monopolar and bipolar mixed output mode in the same execution instrument. In the monopolar and bipolar mixed output mode, the same execution instrument can realize a mixed mode of monopolar mode cutting and bipolar mode hemostasis, overcoming the respective shortcomings of conventional monopolar output and conventional bipolar output, and integrating the respective advantages of monopolar output and bipolar output.
[0077] In the monopolar and bipolar mixed output mode, the bipolar instrument 7 can be used for cutting using the monopolar mode, so that one execution end of the bipolar instrument 7 can also have a higher energy density; and with the help of the cutting force of the bipolar instrument 7, the bipolar instrument 7 can complete the cutting function at low power, thereby greatly reducing the damage caused to the patient during the operation.
[0078] In the monopolar and bipolar mixed output mode, the coagulation nature of the bipolar instrument 7 is still bipolar coagulation. Compared with the coagulation effect of the monopolar mode, the advantage of bipolar coagulation is that within a certain depth of the coagulation site, the power is more concentrated and the coagulation layer is thicker, thereby having a better hemostatic effect on the bleeding point.
[0079] In addition, the present invention has the above three working modes at the same time, and the output mode can be switched arbitrarily according to surgical needs with the cooperation of the executing instrument.
[0080] It should be noted that the above are only preferred embodiments of the present invention, but the design concept of the invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept also fall within the scope of protection of the present invention.
