Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to an electrosurgical workstation, a control method for the electrosurgical workstation, and an electrosurgical device. Background Technology

[0002] Electrosurgery is a surgical treatment method that uses the coagulation and cauterization effects of high-frequency current. Generally, it works by conducting heat to the tissue or generating a thermal reaction in the tissue through the current. Commonly used electrosurgery procedures include electrocoagulation and electrocautery.

[0003] Electrosurgical procedures can be performed using an electrosurgical workstation. This workstation integrates numerous high-frequency surgical instruments, including high-frequency electrosurgical units, large vessel closure systems, ultrasonic scalpels, argon plasma coagulation devices, and endoscopic electrosurgical units. High-frequency electrosurgical workstations primarily offer monopolar and bipolar output modes, differing mainly in energy conduction. In monopolar mode, one electrode serves as the working electrode, while the other, placed away from the working electrode, acts as a return electrode. In bipolar mode, the current flows only a short distance between the two electrodes, eliminating the need for a return electrode. Furthermore, within each output mode, different surgical instruments are required to perform various functions to meet different surgical requirements. For example, surgical instruments may need to perform cutting or electrocoagulation. Different output modes and functions necessitate different waveforms and currents from the electrosurgical workstation. Integrating multiple output modes and functions increases the size of the electrosurgical workstation, raises circuit complexity, and reduces output stability. Summary of the Invention

Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0044] While this invention makes various references to certain modules in systems according to embodiments of the invention, any number of different modules can be used and run on computing devices and / or processors.

[0046] Figure 1 This is a schematic diagram of the structure of an electrosurgical device provided in an embodiment of the present invention. Figure 1 As shown, the electrosurgical device includes an electrosurgical workstation 10 and electrosurgical tools 20 connected to the workstation. The electrosurgical workstation 10 outputs current signals of different waveforms and magnitudes according to a set mode. The electrosurgical tools 20 can select a single-stage electrosurgical knife or a bipolar electrosurgical knife according to the set mode.

[0047] Figure 2 This is a schematic diagram of the structure of an electrosurgical workstation provided in an embodiment of the present invention. Figure 2 As shown, the workstation includes a first processor 101, a switching circuit 102 connected to the first processor 101, and a processing circuit 103 connected to the switching circuit 102. The processing circuit 103 includes a filter circuit 1031 and a transformer circuit 1032 connected to the filter circuit 1031. The first processor 101 is used to generate a corresponding control signal based on mode setting information; the switching circuit 102 is used to switch the filter circuit 1031 and the transformer circuit 1032 based on the control signal to obtain a corresponding signal; and a high-frequency output circuit 104 is used to output the signal.

[0048] The signal is typically a high-frequency signal with a frequency greater than 300kHz.

[0049] In this embodiment, the first processor 101 generates a corresponding control signal based on mode setting information; the switching circuit 102 switches the filter circuit 1031 and the transformer circuit 1032 based on the control signal to obtain the corresponding signal. Compared with the prior art, this technical solution uses a switching method to achieve rapid switching of workstation modes, with lower circuit complexity, reduced size of the electrosurgical workstation, and improved output stability of the electrosurgical workstation.

[0050] In some embodiments, the transformer circuit 1032 includes two output terminals and at least three coil terminals; the filter circuit 1031 includes at least one filter unit for switching. The switching circuit 102 switches the corresponding coil terminal to the corresponding output terminal based on the control signal; the switching circuit 102 switches whether the corresponding filter unit is connected in parallel between the corresponding two coil terminals based on the control signal.

[0051] It is understandable that different coil terminals correspond to different numbers of coil turns on the secondary side of the transformer, which in turn correspond to different output voltages. By switching the corresponding coil terminal to the corresponding output terminal based on a control signal, the corresponding output voltage is obtained. Then, by switching whether the corresponding filter unit is connected in parallel between the two corresponding coil terminals based on the control signal, the frequency and waveform are controlled, thereby obtaining the corresponding signal.

[0052] In some embodiments, the control signal includes a first control signal and a second control signal, and the switching circuit 102 includes: a first switching unit for switching the transformer circuit 1032 based on the first control signal; and a second switching unit for switching the filter circuit 1031 based on the second control signal.

[0053] In this embodiment, the first switching unit switches the transformer circuit 1032 based on the first control signal, and the second switching unit switches the filter circuit 1031 based on the second control signal. The separate switching method improves the stability of the workbench operation.

[0054] In some embodiments, the transformer circuit 1032 includes a transformer, the transformer including at least three coil terminals; the first switching unit includes a first switching switch and a second switching switch connected to the first switching switch, the first switching switch and the second switching switch being respectively connected to the corresponding coil terminals, and the coil terminals being switched to the output terminals through the first switching switch and the second switching switch based on the first control signal.

[0055] The position and number of coil ends are determined according to the setting mode of the workbench. Based on the first control signal, the corresponding coil ends are switched to the corresponding output ends via the first and second switching switches, thereby realizing the switching of the transformer circuit 1032. This switching method is fast and the circuit structure is relatively simple.

[0056] In some embodiments, the filter circuit 1031 includes at least one filter unit connected to the secondary side of the transformer circuit 1032, and the filter unit includes at least one capacitor; the second switching unit is connected to the at least one capacitor, and switches whether the corresponding capacitor is connected in parallel between the corresponding two coil terminals based on the second control signal, so as to realize the switching of the filter circuit 1031.

[0057] The number of capacitors and the filtering coefficients included in the filtering unit can be determined based on the current signal corresponding to the set mode. The filtering circuit 1031 is switched by switching whether the corresponding capacitors are connected in parallel between the two corresponding coil terminals based on the second control signal. This switching method is fast and the circuit structure is relatively simple.

[0058] In one embodiment, the transformer includes a first coil terminal, a second coil terminal, and a third coil terminal. The first switching unit includes a first switching switch and a second switching switch. The sixth switching terminal of the first switching switch is connected to the second switching terminal of the second switching switch. The fifth switching terminal of the first switching switch is connected to the first coil terminal of the transformer. The seventh switching terminal of the first switching switch is connected to the second coil terminal of the transformer. The third switching terminal of the second switching switch is connected to an output terminal of the transformer. The fourth switching terminal of the second switching switch is connected to the third coil terminal of the transformer.

[0059] The filtering circuit 1031 includes a first filtering unit and a second filtering unit. The first filtering unit includes a first capacitor, and the second filtering unit includes a second capacitor. The second switching unit includes a third switching switch and a fourth switching switch. The third switching switch is connected in series with the first capacitor and switches whether the first capacitor is connected in parallel between the corresponding two coil terminals based on the second control signal.

[0060] The fourth switching switch is connected in series with the second capacitor, and switches whether the second capacitor is connected in parallel between the corresponding two coil terminals based on the second control signal.

[0061] Figure 3 This is a circuit diagram of an electrosurgical workstation provided in an embodiment of the present invention. Figure 3As shown, the transformer circuit 1032 includes a transformer T1, which has a first coil terminal OUT_SEL1, a second coil terminal OUT_SEL2, a third coil terminal OUT_SEL3, and a fourth coil terminal OUT_PUBLIC. The first switch is a relay K6, the second switch is a relay K7, the third switch is a relay K4, and the fourth switch is a relay K5. Relays K4-K7 are all eight-pin relays. The filter circuit 1031 includes a first filter unit and a second filter unit. The first filter unit includes a capacitor C138, and the second filter unit includes a capacitor C140. In addition, the filter circuit 1031 also includes an inductor L1 connected in series to the first input terminal VON1 of the transformer circuit 1032, capacitors C135, C136, and C137 connected in parallel to the second input terminal VON2 of the transformer circuit 1032, a capacitor C5 connected in parallel to the primary side of the transformer T1, a capacitor C11 connected between the fourth coil terminal OUT_PUBLIC and the first output terminal OUT1, and a capacitor C2 connected in series between the second output terminal OUT2_FRONT of the transformer circuit 1032.

[0062] When the fifth and sixth switching terminals of relay K6 are connected and the second and third switching terminals of relay K7 are connected, the switching output terminal OUT_SEL is connected to the first coil terminal OUT_SEL1. At this time, the first coil value is applied, and the turns ratio of the primary coil pins 4-8 and the secondary coil pins 9-11 is 11:33. The input / output voltage ratio is equal to the primary / secondary turns ratio. When the sixth and seventh switching terminals of relay K6 are connected and the second and third switching terminals of relay K7 are connected, the switching output terminal OUT_SEL is connected to the second coil terminal OUT_SEL2. At this time, the second coil value is applied, and the turns ratio of the primary coil pins 4-8 and the secondary coil pins 9-13 is 11:46. The input / output voltage ratio is equal to the primary / secondary turns ratio. When the third switching terminal of relay K7 is connected to the fourth switching terminal, the switching output terminal OUT_SEL is connected to the third coil terminal OUT_SEL3. At this time, the third coil value is connected, and the turns ratio of the primary coil pins 4-8 and the secondary coil pins 9-16 is 11:92. The input / output voltage ratio is equal to the primary / secondary turns ratio.

[0063] When the sixth and seventh switching terminals of relay K6 are on, and the second and third switching terminals of relay K7 are on, the fifth and sixth switching terminals of control relay K4 are on, so that capacitor C138 is connected in parallel between the second coil terminal OUT_SEL2 and the fourth coil terminal OUT_PUBLIC. When the fifth and sixth switching terminals of relay K6 are on, and the second and third switching terminals of relay K7 are on, the third and fourth switching terminals of control relay K4 are on, so that capacitor C140 is connected in parallel between the first coil terminal OUT_SEL1 and the fourth coil terminal OUT_PUBLIC. When the third and fourth switching terminals of relay K7 are on, the switching terminals of control relays K4 and K5 are not on, and at this time, neither capacitor C138 nor capacitor C140 is connected to the transformer coil terminals.

[0064] When the first coil value is connected and capacitor C138 is connected, a first type of signal is output; when the second coil value is connected and capacitor C138 is connected, a second type of signal is output; when the third coil value is connected and capacitor C138 is connected, a third type of signal is output. It should be noted that each type of signal can correspond to one or more setting modes.

[0065] In this embodiment, the workstation's setting modes include: monopolar automatic electrocautery, monopolar bloodless electrocautery, monopolar gentle electrocoagulation, monopolar strong electrocoagulation, monopolar rapid electrocoagulation, bipolar automatic electrocautery, bipolar bloodless electrocautery, bipolar gentle electrocoagulation, and bipolar strong electrocoagulation. Different setting modes correspond to different mode setting information.

[0066] The setting modes corresponding to the first type of signal include monopolar automatic electrosurgical resection, monopolar gentle electrocoagulation, bipolar automatic electrosurgical resection, and bipolar gentle electrocoagulation; the setting modes corresponding to the second type of signal include bipolar bloodless electrosurgical resection and bipolar strong electrocoagulation; and the setting modes corresponding to the third type of signal include monopolar bloodless electrosurgical resection, monopolar rapid electrocoagulation, and monopolar strong electrocoagulation.

[0067] Among them, the unipolar automatic electrosurgery outputs a continuous waveform with a peak-to-peak value of 1480, a power of 300W, and a waveform coefficient of 1.4; the unipolar gentle electrocoagulation outputs a continuous waveform with a peak-to-peak value of 380, a power of 200W, and a waveform coefficient of 1.4; the bipolar automatic electrosurgery outputs a continuous waveform with a peak-to-peak value of 960, a power of 100W, and a waveform coefficient of 1.4; the bipolar gentle electrocoagulation outputs a continuous waveform with a peak-to-peak value of 380, a power of 120W, and a waveform coefficient of 1.4; and the bipolar anemic electrosurgery outputs an intermittent waveform with a peak-to-peak value of 21. 00, power is 100W, waveform coefficient is 3.6; Bipolar strong electrocoagulation is a bipolar intermittent waveform output, its peak-to-peak value is 2100, power is 90W, waveform coefficient is 3.8; Unipolar bloodless electrocoagulation is a unipolar intermittent waveform output, its peak-to-peak value is 2900, power is 200W, waveform coefficient is 3.2, 3.3, or 3.6; Unipolar rapid electrocoagulation is a unipolar intermittent waveform output, its peak-to-peak value is 500, power is 200W, waveform coefficient is 5.2; Unipolar strong electrocoagulation is a unipolar intermittent waveform output, its peak-to-peak value is 3600, power is 120W, waveform coefficient is 5.0.

[0068] It should be noted that the peak-to-peak value, power, and waveform coefficient of the signal waveform corresponding to each mode can be slightly adjusted according to the actual situation, and this embodiment does not limit their specific values.

[0069] In the unipolar automatic electrosurgical cut, unipolar gentle electrocoagulation, bipolar automatic electrosurgical cut, and bipolar gentle electrocoagulation modes, the output terminal OUT_SEL is connected to the first coil terminal OUT_SEL1 by switching relays K6 and K7, and capacitor C140 is connected in parallel to the fourth coil terminal OUT_PUBLIC and the first coil terminal OUT_SEL1 by switching relay K5. In the bipolar bloodless electrosurgical cut and bipolar strong electrocoagulation modes, the output terminal OUT_SEL is connected to the second coil terminal OUT_SEL2 by switching relays K6 and K7, and capacitor C138 is connected in parallel to the fourth coil terminal OUT_PUBLIC and the second coil terminal OUT_SEL2 by switching relay K4. In the unipolar bloodless electrosurgical cut, unipolar rapid electrocoagulation, and unipolar strong electrocoagulation modes, the output terminal OUT_SEL is connected to the third coil terminal OUT_SEL3 by switching relays K6 and K7, and capacitors C138 and C140 are not connected.

[0070] In another embodiment, the filter circuit 1031 includes at least one filter unit connected to the primary side of the transformer circuit 1032. The filter unit includes at least one capacitor and at least one inductor. The second switching unit is connected to the at least one capacitor and the at least one inductor. The switching is achieved by switching whether the capacitor corresponding to the second control signal is connected in parallel between the two input terminals of the transformer circuit 1032, and whether the inductor corresponding to the switching is connected in series with one input terminal of the transformer circuit 1032.

[0071] Figure 4 This is a circuit diagram of an electrosurgical workstation provided in another embodiment of the present invention. (See diagram below.) Figure 4 As shown, the transformer circuit 1032 includes a transformer T2, and the filter circuit 1031 includes a first filter unit, which includes a capacitor C6 and an inductor L1. In addition, the filter circuit 1031 also includes capacitors C5 and C4 connected in parallel to the primary side of the transformer T1, an inductor L connected in series to the first input terminal VON2 of the transformer circuit 1032, a capacitor C11 connected between the fourth coil terminal OUT_PUBLIC and the first output terminal OUT1, and a capacitor C2 connected in series between the second output terminal OUT2_FRONT of the transformer circuit 1032.

[0072] In this embodiment, when the output terminal OUT_SEL is connected to the second coil terminal OUT_SEL2, the turns ratio of the primary coil pins 4-8 and the secondary coil pins 9-13 is 25:46, and the input / output voltage ratio is equal to the primary / secondary turns ratio. When the output terminal OUT_SEL is connected to the third coil terminal OUT_SEL3, the turns ratio of the primary coil pins 4-8 and the secondary coil pins 9-16 is 25:92, and the input / output voltage ratio is equal to the primary / secondary turns ratio. With the same input voltage at pins 4-8, the output voltage at pins 9-16 is twice that at pins 9-13. Therefore, the output mode of pins 9-13 is bipolar, while the output of pins 9-16 is used for unipolar mode with higher output voltage requirements.

[0073] In this embodiment, the set modes include: monopolar automatic electrocautery, monopolar gentle electrocoagulation, monopolar strong electrocoagulation, monopolar rapid electrocoagulation, bipolar automatic electrocautery, bipolar gentle electrocoagulation, and bipolar strong electrocoagulation.

[0074] In unipolar strong electrocoagulation, unipolar fast electrocoagulation, and bipolar strong electrocoagulation modes, a modulated waveform with a certain duty cycle is output at a lower modulation frequency. Modes that output continuous modulated waveforms, such as automatic electrocution and gentle electrocoagulation, have higher modulation frequencies. Using the filter inductor in the filter circuit 1031 with a higher matching frequency to filter the lower-frequency modulated waveform will distort the modulated waveform. Therefore, in unipolar strong electrocoagulation, unipolar fast electrocoagulation, and bipolar strong electrocoagulation modes, the filter circuit 1031 is switched to reduce the filter inductance, controlling the relay to... Figure 4 When the inductor L1 is short-circuited, the control relay is activated. Figure 4 The capacitor C6 in the circuit ensures that the filtering performance in other low-frequency bands remains unchanged. In bipolar automatic switching, bipolar gentle electrocoagulation, unipolar automatic switching, and unipolar gentle electrocoagulation modes, the relay connects both inductors L1 and L2 normally and disconnects capacitor C6.

[0075] In some embodiments, such as Figure 5 As shown, the workstation further includes: an inverter circuit 105 for converting the input DC signal into an AC signal; and a second processor 106 for sending a fourth control signal to the first processor 101 when it is confirmed that the status signal of the switching circuit 102 does not correspond to the mode setting information, so as to instruct the first processor 101 to control the inverter circuit 105 to stop working.

[0076] The second processor 106 can independently monitor the status signal of the switching circuit 102 and feed the status signal back to the first processor 101. If the second processor 106 confirms that the status signal does not correspond to the mode setting information, it sends a fourth control signal to the first processor 101 to instruct the first processor 101 to control the inverter circuit 105 to stop working, thereby ensuring the safety of the workstation and improving the stability of the electrosurgical workbench.

[0077] In other embodiments, if the second processor 106 confirms that the status signal of the switching circuit 102 does not correspond to the mode setting information, it sends a third control signal to the inverter circuit 105 to control the inverter circuit 105 to stop working. By using the second processor 106 to control the inverter circuit 105 to stop working, the processing pressure of the first processor 101 is relieved, ensuring the safety of the workstation and improving the stability of the electrosurgical workbench operation.

[0078] In some embodiments, such as Figure 6 As shown, the workstation further includes a display module 107 for displaying alarm information, wherein the alarm information is generated by the second processor 106 when it is confirmed that the status signal of the switching circuit 102 does not correspond to the mode setting information.

[0079] If the second processor 106 confirms that the status signal and the mode setting information are inconsistent, the second processor 106 generates an alarm message and sends the alarm message to the display module 107, which then displays the alarm message.

[0080] In some other embodiments, the display module 107 may also be connected to the first processor 101. If the second processor 106 confirms that the status signal and the mode setting information are inconsistent, the second processor 106 sends a notification message to the first processor 101. The first processor 101 generates an alarm message and sends the alarm message to the display module 107, which then displays the alarm message.

[0081] Figure 7 This is a flowchart illustrating a control method for an electrosurgical workstation according to an embodiment of the present invention. Figure 7 As shown, the method includes the following steps:

[0082] S701: Obtain mode setting information;

[0083] S702: Based on the mode setting information, generate a corresponding control signal. The control signal is used to control the switching circuit to switch the transformer circuit and the filter circuit to output the corresponding signal.

[0084] In this embodiment, mode setting information is acquired, and a corresponding control signal is generated based on the mode setting information. The filter circuit and the transformer circuit are switched based on the control signal to obtain the corresponding signal. Compared with the prior art, this technical solution uses a switching method to achieve rapid switching of workstation modes.

[0085] In one embodiment, an electrosurgical device is provided, including the electrosurgical workstation described in the above embodiments, and a single-polar or bipolar electrosurgical tool connected to the electrosurgical workstation.
