[0002] Currently, the energy host in high-frequency energy surgical equipment can be connected to the surgical electrode and the neutral plate through two host interfaces respectively. The processing module in the energy host can generate current and transmit it to the surgical electrode through one of the host interfaces. After the surgical electrode and the neutral plate form a circuit through the skin tissue, the current can be transmitted to the neutral plate. The neutral plate then transmits the current to the ground terminal in the energy host through the other host interface, forming a ground current. The surgical electrode can then generate energy based on this ground current and act on the skin tissue to complete the surgery.

If the specific posture changes, the directional indicator will also change accordingly.
[0039] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, the user should consider such a combination of technical solutions to be non-existent and not within the scope of protection claimed by this utility model.
[0040] It should be noted that currently, the energy host in high-frequency energy surgical devices can be connected to the surgical electrodes and the neutral electrode plate via two host interfaces, respectively. (See reference...) Figure 1 , Figure 1 This is a schematic diagram of a traditional power generator connection, such as... Figure 1 As shown, the processing module 13 in the energy host 1 can be connected to the foot pedal (not shown in the figure). When the user steps on the foot pedal, a control signal is generated to the processing module 13, and the processing module 13 can generate current through one of the host interfaces (i.e., Figure 1 The first host interface 11 transmits the current to the surgical electrode 2. After the surgical electrode 2 and the neutral electrode 3 form a circuit through the skin tissue, the current can be transmitted to the neutral electrode 3. The neutral electrode 3 then transmits the current through another host interface (i.e., Figure 1 The second host interface 12) transmits data to the grounding terminal (i.e., the energy host 1) within the energy host 1. Figure 1 The GND1 is used to generate a ground current, which in turn allows the surgical electrode 2 to generate energy that acts on the skin tissue, thereby completing the surgery.
[0041] In the prior art, when connected to the ground terminal (i.e. Figure 1 The host interface connected to GND1 (i.e.) Figure 1 The second host interface 12) and the grounding terminal (i.e. Figure 1 When a fault occurs in the grounding loop between GND1 and GND2, such as an open circuit, the processing module 13 will not issue an alarm and will continue to output energy, which may easily lead to safety hazards. Therefore, how to enable the energy host 1 to detect whether the loop is faulty is an urgent problem to be solved.
[0042] To address the aforementioned technical issues, this embodiment provides an energy host capable of detecting grounding loop faults. Since a detection module is also provided between the processing module and the host interface, when the detection module receives a ground current, it can collect and generate a fault signal and transmit the fault signal to the processing module. This allows the processing module to detect grounding loop faults upon receiving the fault signal, thereby improving safety.
[0043] For ease of understanding, the following is combined with Figures 2 to 4 The energy host capable of detecting grounding loop faults provided in the embodiments of this application will be described in detail.
[0044] Reference Figure 2 , Figure 2 This is a schematic diagram of the first embodiment of the energy host that can detect grounding loop faults, as proposed in this utility model.
[0045] like Figure 2 As shown, in this embodiment, the energy host 1 includes: a processing module 13, a host interface (i.e., ... Figure 2 The second host interface 12) and the first grounding terminal GND1 are provided. The host interface can be plugged into the neutral plate 3 and short-circuited to the first grounding terminal GND1. The host interface is used to transmit the ground current received by the neutral plate 3 to the first grounding terminal GND1.
[0046] It is understood that the aforementioned processing module 13 can be an output control module within the energy host 1, specifically consistent with the processing module 13 in a traditional energy host 1, and can employ components such as microprocessors; this embodiment does not impose any limitations on this. The aforementioned first grounding terminal GND1 can be a grounding post of the energy host's chassis, or of course, it can be other grounding ports; this embodiment does not impose any limitations on this.
[0047] It is also understood that, in this embodiment, the loop between the second host interface 12 and the first grounding terminal GND1 is referred to as the grounding loop. In this embodiment, the energy host 1 is also provided with a first host interface 11 and a surgical electrode 2. The processing module 13 transmits the generated grounding current to the surgical electrode 2 through the first host interface 11, and the surgical electrode 2 then transmits it to the second host interface 12 through the neutral plate 3. The second host interface 12 then transmits the grounding current to the first grounding terminal GND1 through the grounding loop, thereby forming a loop. This part is consistent with the conventional implementation process, and will not be described in detail in this embodiment.
[0048] When a fault (e.g., an open circuit) occurs in the grounding loop between the second host interface 12 and the first grounding terminal GND1, the conventional processing module 13 will not issue an alarm. During operation, the processing module 13 will continue to output grounding current, which can easily lead to safety hazards. Therefore, in this embodiment, the energy host 1 further includes a detection module 14.
[0049] The detection module 14 is connected to the host interface and the processing module 13 respectively. The detection module 14 is used to generate a fault signal when it receives the ground current and transmit the fault signal to the processing module 13 so that the processing module 13 can know that the grounding loop has failed.
[0050] Since the present invention also provides a detection module 14 between the processing module 13 and the host interface, when the detection module 14 receives the ground current, it generates a fault signal and transmits the fault signal to the processing module 13, thereby enabling the processing module 13 to know that the grounding loop has failed, thus improving safety.
[0051] It should be understood that, as Figure 2 As shown, in this embodiment, an additional detection module 14 can be provided inside the energy host 1, between the second host interface 12 and the processing module 13. The detection module 14 can be a module that can receive grounding current and generate a fault signal when a grounding loop fault occurs. The fault signal can be a signal characterizing the fault state of the grounding loop.
[0052] In actual use, when the grounding loop is normal, the second host interface 12 can directly transmit the grounding current to the first grounding terminal GND1. At this time, the detection module 14 can be short-circuited. The detection module 14 does not receive the grounding current output by the second host interface 12, and therefore no fault signal is generated and transmitted to the processing module 13. The processing module 13 can determine that the grounding loop is normal when no fault signal is received.
[0053] When a grounding loop fails, the second host interface 12 can transmit the grounding current to the detection module 14. The detection module 14 can collect the grounding current and obtain the fault signal, and transmit the fault signal to the processing module 13. After receiving the fault signal, the processing module 13 can know that a grounding loop has failed, thus enabling the processing module 13 to detect the grounding loop and improve safety.
[0054] Simultaneously, after determining that a fault has occurred, the processing module 13 can provide a series of prompts. For example, in this embodiment, the processing module 13 can be connected to a prompt module. After receiving a fault signal, the processing module 13 can generate a prompt signal to the prompt module, which will then issue an alarm. Furthermore, in this embodiment, the prompts can be provided through various means, including but not limited to displaying information on a screen, using LEDs for visual prompts, or using a buzzer for audible prompts. This embodiment does not impose any limitations on these methods.
[0055] Furthermore, in order to enable the grounding current to be transmitted from the second host interface 12 to the detection module 14, in this embodiment, the detection module 14 includes: a second grounding terminal GND2 and a detection submodule 141;
[0056] The detection submodule 141 is connected to the host interface, the second ground terminal GND2 and the processing module 13. The detection submodule 141 is used to transmit the ground current to the second ground terminal GND2 when the ground current is received, and to collect the ground current to obtain a fault signal.
[0057] The detection submodule 141 is also used to transmit the fault signal to the processing module 13.
[0058] It should be noted that when the grounding loop is in a normal state, the second host interface 12 directly transmits the grounding current to the first grounding terminal GND1, and no grounding current is transmitted to the second grounding terminal GND2. The detection submodule 141 does not generate a fault signal, and the processing module 13 can know that the grounding loop is in a normal state when it does not receive a fault signal. When the grounding loop is faulty, the second host interface 12 transmits no grounding current to the first grounding terminal GND1, but transmits it to the second grounding terminal GND2. Then the detection submodule 141 can collect the grounding current and generate a fault signal to be transmitted to the processing module 13. When the processing module 13 receives the fault signal, it can determine that the grounding loop is faulty.
[0059] In this embodiment, a detection module 14 is also provided between the processing module 13 and the host interface. When the detection module 14 receives a ground current, it generates a fault signal and transmits the fault signal to the processing module 13, thereby enabling the processing module 13 to know that a grounding loop fault has occurred, thus improving safety.
[0060] Reference Figure 3 , Figure 3 The circuit diagram is shown in the second embodiment of the energy host 1 that can detect grounding loop faults, as proposed in this utility model.
[0061] like Figure 3 As shown, it should be noted that in this embodiment, the second host interface 12 (i.e. Figure 3 J1) can be configured with two output terminals, wherein the first output terminal of the second host interface 12 can be the first pin of the second host interface 12, and the first output terminal of the second host can be connected to the first ground terminal GND1 (i.e. Figure 3 Connect GND1.
[0062] The second output terminal of the second host interface 12 can be the second pin of the second host, and the second output terminal of the second host interface 12 (i.e. Figure 3The output terminal (Detect) can be connected to the processing module 13 (not shown in the figure). In the conventional scheme, the function of this output terminal is to enable the processing module 13 to detect whether the second host interface 12 is properly inserted into the neutral plate 3. That is, when the neutral plate 3 is properly inserted into the second host interface 12, the second output terminal of the second host interface 12 can output an insertion signal to the processing module 13. The processing module 13 can then know that the neutral plate 3 is properly inserted, and thus the processing module 13 outputs a grounding current to operate normally. When the neutral plate 3 is not properly inserted into the second host interface 12, the second output terminal of the second host interface 12 does not transmit an insertion signal to the processing module 13. The processing module 13 can then know that the neutral plate 3 is improperly inserted, and thus the processing module 13 does not output a grounding current. The processing module 13 can also issue an alarm through the display screen set on the energy host 1.
[0063] Therefore, in this embodiment, the detection module 14 can be connected to the first grounding terminal GND1 of the second host interface 12, so that the detection module 14 can receive the grounding current.
[0064] Furthermore, considering that the grounding current directly acquired is an analog signal, while the processing module 13 can recognize digital signals, in this embodiment, the detection submodule 141 includes: an acquisition unit 1411 and a conversion unit 1412.
[0065] The acquisition unit 1411 is connected to the host interface (i.e. Figure 3 The second host interface 12), the second grounding terminal GND2, and the conversion unit 1412 are included. The acquisition unit 1411 is used to transmit the ground current to the second grounding terminal GND2 when the ground current is received, and to acquire the ground current to obtain an analog signal.
[0066] The conversion unit 1412 is connected to the processing module 13. The conversion unit 1412 is used to convert the analog signal into a fault signal and transmit the fault signal to the processing module 13.
[0067] It is understood that, in this embodiment, the acquisition unit 1411 can be specifically connected to the second output terminal of the second host interface 12.
[0068] The aforementioned acquisition unit 1411 can be any unit for acquiring current, such as a current transformer T1, etc., and this embodiment does not impose any limitations on it. The aforementioned conversion unit 1412 can be a unit for performing analog-to-digital conversion, such as an analog-to-digital converter, etc., and this embodiment does not impose any limitations on it.
[0069] In actual use, when the grounding loop is normal, the acquisition unit 1411 does not receive the ground current, and therefore no analog signal is generated. The conversion unit 1412 does not generate a fault signal and transmits it to the processing module 13. The processing module 13 determines that the grounding loop is normal. When the grounding loop is abnormal, the acquisition unit 1411 receives the ground current and transmits it to the second grounding terminal GND2. At the same time, the acquisition module can acquire the ground current and generate an analog signal, which is transmitted to the conversion unit 1412. The conversion unit 1412 converts the analog signal into a digital fault signal and transmits it to the processing module 13. The processing module 13 can determine that the grounding loop is abnormal.
[0070] Furthermore, in order to enable the second host interface 12 to transmit the grounding current to the first grounding terminal GND1 when the grounding loop is normal, and to transmit it to the second grounding terminal GND2 when the grounding loop is abnormal, as follows: Figure 3 As shown, in this embodiment, the acquisition unit 1411 includes: a first capacitor C1 and a current transformer T1;
[0071] The first output terminal of the host interface is connected to the first ground terminal GND1 and the first terminal of the first capacitor C1. The second output terminal of the host interface is connected to the processing module 13. The second terminal of the first capacitor C1 is connected to the first input terminal of the current transformer T1. The second input terminal of the current transformer T1 is connected to the second ground terminal GND2. Both the first output terminal and the second output terminal of the current transformer T1 are connected to the conversion unit 1412.
[0072] It should be understood that the aforementioned current transformer T1 can be a high-frequency current transformer T1, specifically a TAK12-005 current transformer T1, although other models can also be used; this embodiment does not impose any limitations on this. The first input terminal of the aforementioned current transformer T1 can be the first pin of the current transformer T1, which can be used to receive grounding current; the second input terminal of the aforementioned current transformer T1 can be the second pin of the current transformer T1, which can be used to transmit grounding current to the second grounding terminal GND2; the first output terminal of the aforementioned current transformer T1 can be the third pin of the current transformer T1, and the second output terminal of the aforementioned current transformer T1 can be the fourth pin of the current transformer T1, both of which can be used to output analog signals.
[0073] In actual use, when the grounding loop is normal, there is an impedance between the first capacitor C1 and the second grounding terminal GND2. Therefore, when the grounding loop is normal, it will short-circuit between the first capacitor C1 and the second grounding terminal GND2, causing the acquisition unit 1411 and the conversion unit 1412 in this embodiment to be invalid. It has no effect on the previous loop, and the second host interface 12 transmits the grounding current to the first grounding terminal GND1. When the grounding loop fails, the impedance of the loop between the first capacitor C1 and the second grounding terminal GND2 will be very small compared to the case of a grounding loop failure. Therefore, the second host interface 12 can transmit the grounding current to the first capacitor C1. The first capacitor C1 then transmits the current to the second grounding terminal GND2 through the current transformer T1, thus forming a loop. At the same time, the current transformer T1 can acquire the grounding current and generate an analog signal to transmit to the conversion unit 1412.
[0074] Furthermore, continue as Figure 3 As shown, in order to collect grounding current, in this embodiment, the collection unit 1411 further includes: a first resistor R1 to a third resistor R3 and a second capacitor C2;
[0075] The first end of the first resistor R1 is connected to the first output terminal of the current transformer T1 and the first end of the second resistor R2. The second end of the first resistor R1 is connected to the second output terminal of the current transformer T1 and the first end of the third resistor R3. The second end of the second resistor R2 is connected to the first end of the second capacitor C2 and the conversion unit 1412. The second end of the third resistor R3 is connected to the second end of the second capacitor C2 and the conversion unit 1412.
[0076] It should be noted that the first resistor R1 to the third resistor R3 mentioned above can prevent the current value of the analog signal acquired by the current transformer T1 from being too large and affecting the normal operation of subsequent components. Therefore, in this embodiment, the first resistor R1 to the third resistor R3 and the second capacitor C2 can be set, and the analog signal is transmitted to the acquisition unit 1411 through the second terminal of the second resistor R2 and the second terminal of the third resistor R3. The resistance values of the first resistor R1 to the third resistor R3 and the capacitance value of the second capacitor C2 can be set according to the actual situation, and this embodiment does not impose any restrictions on them.
[0077] Furthermore, in order to achieve analog-to-digital conversion, in this embodiment, the conversion unit 1412 includes: a conversion chip U1;
[0078] The first input terminal and the second input terminal of the conversion chip U1 are both connected to the acquisition unit 1411. The first power supply terminal of the conversion chip U1 is connected to the first power supply, the second power supply terminal of the conversion chip U1 is connected to the second power supply, the reference terminal of the conversion chip U1 is connected to the third ground terminal GND3, and the output terminal of the conversion chip U1 is connected to the processing module 13.
[0079] It is understood that the aforementioned conversion chip U1 can be any chip that implements analog-to-digital conversion. In this embodiment, an operational amplifier of model AD620 is used, but other models can also be used. This embodiment does not limit this.
[0080] It should be understood that the first input terminal of the aforementioned conversion chip U1 can be the third pin of the conversion chip U1, and the second input terminal of the aforementioned conversion chip U1 can be the second pin of the conversion chip U1. Specifically, the first input terminal of the aforementioned conversion chip U1 can be connected to the second terminal of the second resistor R2, and the second input terminal of the aforementioned conversion chip U1 can be connected to the second terminal of the third resistor R3. The first power supply terminal of the aforementioned conversion chip U1 can be the seventh pin of the conversion chip U1, which can be connected to the +12V power supply (i.e., the aforementioned first power supply), and the second power supply terminal of the aforementioned conversion chip U1 can be the fourth pin of the conversion chip U1, which can be connected to the -12V power supply (i.e., the aforementioned second power supply).
[0081] It should also be understood that the reference terminal of the aforementioned conversion chip U1 can be the fifth pin of the conversion chip U1, which can be connected to the third ground terminal GND3 to provide a ground reference for the conversion chip U1. The output terminal of the aforementioned conversion chip U1 can be the sixth pin of the conversion chip U1, which can be used to transmit the generated fault signal to the processing module 13 (i.e., Figure 3 Medium ERR).
[0082] It should be noted that in this embodiment, one pin of the processing module 13 can be configured to receive the aforementioned fault signal and determine whether the grounding loop is abnormal based on the fault signal. It is important to emphasize that since the processing module 13 can consider the pin to be at a low level when it does not receive the fault signal and at a high level when it receives the fault signal, the processing module 13 can determine whether the grounding loop is abnormal by identifying the high and low levels.
[0083] In actual use, the first input terminal and the second input terminal of the conversion chip U1 can receive analog signals, and the generated fault signal is transmitted to the processing module 13 through the sixth pin of the conversion chip U1, thereby realizing analog-to-digital conversion.
[0084] Furthermore, in order to adjust the amplification factor of the conversion chip U1, in this embodiment, the conversion unit 1412 further includes: a fourth resistor R4;
[0085] The first end of the fourth resistor R4 is connected to the first adjustment terminal of the conversion chip U1, and the second end of the fourth resistor R4 is connected to the second adjustment terminal of the conversion chip U1.
[0086] It is understood that the first adjustment terminal of the aforementioned conversion chip U1 can be the first pin of the conversion chip U1, and the second adjustment terminal of the aforementioned conversion chip U1 can be the eighth pin of the conversion chip U1. The resistance value of the aforementioned fourth resistor R4 can be set according to the actual situation. In this embodiment, by setting the fourth resistor R4, the amplification factor of the conversion chip U1 can be adjusted by setting different resistance values.
[0087] Furthermore, in order to prevent the voltage value of the analog signal from exceeding a certain threshold and thus damaging the circuit, in this embodiment, the conversion unit 1412 mentioned above further includes: a first bidirectional diode D1;
[0088] The first end of the first bidirectional diode D1 is connected to the fourth ground terminal GND4, and the second end of the first bidirectional diode D1 is connected to the first input terminal of the conversion chip U1.
[0089] The conversion unit 1412 further includes: a second bidirectional diode D2;
[0090] The first end of the second bidirectional diode D2 is connected to the fourth ground terminal GND4, and the second end of the second bidirectional diode D2 is connected to the second input terminal of the conversion chip U1.
[0091] It should be understood that the first bidirectional diode D1 and the second bidirectional diode D2 mentioned above can both be diodes of type SMBJ6.5CA. Of course, other types can also be used, and this embodiment does not limit this.
[0092] It should also be understood that the fourth grounding terminal GND4 may or may not share a terminal with the third grounding terminal GND3, and this embodiment does not impose any restrictions on this.
[0093] In actual use, when the voltage of the analog signal is normal, the second resistor R2 and the third resistor R3 can transmit the analog signal to the conversion chip U1; when the voltage of the analog signal exceeds the threshold of the first bidirectional diode D1 and the second bidirectional diode D2, the first bidirectional diode D1 and the second bidirectional diode D2 are turned on, transmitting the analog signal to the fourth ground terminal GND4, thereby achieving protection.
[0094] Furthermore, considering that the grounding current should be stopped when an abnormality occurs in the grounding loop, in this embodiment, referring to... Figure 4 , Figure 4 The software logic diagram of the processing module 13 in the second embodiment of the energy host 1 capable of detecting grounding loop faults proposed in this utility model embodiment;
[0095] like Figure 4 As shown, for the software control section of the processing module 13, the traditional software control logic of the processing module 13 can be: the foot pedal outputs a control signal to the processing module 13, and the processing module 13 outputs a grounding current (i.e., Figure 4 (Excite energy signal); then the processing module 13 can perform initialization (i.e. Figure 4 The output device is complete. If initialization fails, an error message will be displayed on the screen; if initialization succeeds, the processing module 13 will begin to detect the internal components (i.e., ...). Figure 4 (Inside the detection system), after the internal detection is completed, it can be determined whether the neutral plate 3 is connected (i.e. Figure 4 Whether the neutral plate 3 is connected can be specifically achieved through the second output terminal of the second host interface 12, which will not be elaborated in this embodiment. When the neutral plate 3 is not connected, an abnormality will be displayed on the screen. When the neutral plate 3 is successfully connected, the processing module 13 will start outputting grounding current (i.e., Figure 4 Energy output begins in the middle (and continues to output energy). Figure 4 (Continuous energy output in the middle);
[0096] With the addition of the detection module 14 in this embodiment, the logic of the software control section can be adjusted as follows: After the processing module 13 starts outputting the grounding current, it can detect whether the grounding loop is faulty using the above scheme (i.e., Figure 4 The system monitors whether the neutral electrode plate 3 circuit is normal. If a fault occurs in the grounding circuit, an abnormal output will be displayed on the screen. If the grounding circuit is normal, the processing module 13 will continue to output energy. This ensures the safety of the operation.
[0097] In addition, to achieve the above objectives, this embodiment also provides a surgical device, which includes a surgical electrode 2, a neutral electrode plate 3, and an energy host 1 as described above;
[0098] The energy host 1 is connected to the surgical electrode 2 and the neutral electrode 3 respectively.
[0099] The specific structures of the surgical electrode 2, neutral plate 3, and energy host 1 can all refer to the above embodiments. Since this surgical device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.
[0100] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
