[0037] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0038] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0041] 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.

[0042] It should be noted that currently, the peak output voltage of surgical devices with radio frequency energy functions on the market is generally 200V, but in some cases, higher voltages are required, which are generally achieved by using a transformer to boost the voltage.

[0043] However, because surgical equipment has a high output frequency, typically in the MHz range, the transformer's turns ratio cannot be too high, otherwise parasitic parameters will be large. Therefore, how to improve the peak output voltage of surgical equipment is an urgent problem to be solved.

[0044] To address the aforementioned technical problems, this embodiment provides a surgical device with radio frequency energy functionality. Since the embodiment can additionally include an energy storage module, this module may include only a first energy storage unit or a second energy storage unit, or it may include both. The first energy storage unit can form a first resonant circuit with a first inductor in the transformer, and the second energy storage unit can form a second resonant circuit with a second inductor in the transformer. Compared to existing methods that only use a transformer for voltage boosting, this embodiment can also boost the voltage through the first resonant circuit and / or the second resonant circuit, thereby increasing the peak output voltage of the surgical device.

[0045] It is worth noting that the aforementioned "surgical equipment with radiofrequency energy function" can be a main unit that only has radiofrequency energy function, or it can be a main unit that integrates radiofrequency energy function and other functions. For ease of understanding, for example, a rotary biopsy electrocoagulation main unit has both radiofrequency energy function and the function of biopsy sampling of lesions. During the biopsy sampling process, its radiofrequency energy function can be used to stop bleeding at the wound site or accelerate the speed of lesion resection. It should be noted that the "other functions" here are not limited to the biopsy sampling function.

[0046] For ease of understanding, the following is combined with Figures 1 to 5 The surgical device with radio frequency energy function provided in the embodiments of this application will be described in detail.

[0047] Reference Figure 1 , Figure 1This is a schematic diagram of the structure of the first embodiment of the surgical device with radio frequency energy function proposed in this utility model.

[0048] like Figure 1 As shown, in this embodiment, the surgical device includes: an energy storage module and a transformer T with a first inductor L1, a second inductor L2, and a winding T1. The winding T1 is used to boost the winding input voltage to the winding output voltage. The energy storage module includes:

[0049] The first energy storage unit 1 is connected to the first end of the first inductor L1, and the second end of the first inductor L1 is connected to the input end of the winding T1. The first energy storage unit 1 and the first inductor L1 are connected to form a first resonant circuit, which is used to boost the input voltage of the winding.

[0050] It should be noted that the transformer T in this embodiment can be any transformer used for voltage boosting; this embodiment does not impose any restrictions. In conventional solutions, the input terminal of transformer T can be connected to an external power source to receive the initial voltage provided by the external power source. This external power source can be a mains power source, and the initial voltage can be AC ​​220V, or other initial voltage values; this embodiment does not impose any restrictions. The output terminal of transformer T can be connected to the target load, which can be any load that requires power, such as surgical electrodes. That is, in conventional solutions, the initial voltage provided by the external power source is boosted by transformer T before being transmitted to the target load for use. However, since the output frequency of surgical equipment is relatively high, generally in the MHz range, the turns ratio of transformer T cannot be too high in conventional cases, resulting in a relatively low peak output voltage.

[0051] In this embodiment, refer to Figure 2 , Figure 2 This is a schematic diagram of the equivalent circuit of transformer T in the first embodiment of the surgical device with radio frequency energy function proposed in this utility model. Figure 2 As shown, a conventional transformer T can be equivalently represented as a transformer T with a first inductor L1, a second inductor L2, and a winding T1. The winding T1 is used to boost the winding input voltage to the winding output voltage. At this time, the winding T1 is the winding in an ideal transformer T. The winding input voltage is the voltage received at the input terminal of the winding T1, and the winding output voltage is the voltage output at the output terminal of the winding T1. The first inductor L1 can be the primary leakage inductance of the equivalent transformer T, and the second inductor L2 can be the secondary leakage inductance of the equivalent transformer T.

[0052] In the equivalent case, the above-mentioned transformer T may also include: a first resistor R1, a second resistor R2, a magnetizing resistor Rm, and a magnetizing inductance Lm;

[0053] In the conventional case, the first terminal of the first resistor R1 can be connected to the first terminal of the external power supply (i.e., Figure 2 In the first circuit (①), the second end of the first resistor R1 is connected to the first end of the first inductor L1. The second end of the first inductor L1 is connected to the first end of the magnetizing resistor Rm, the first end of the magnetizing inductor Lm, and the first input terminal of the winding T1. The second input terminal of the winding T1 is connected to the second end of the magnetizing resistor Rm, the second end of the magnetizing inductor Lm, and the second terminal of the external power supply (i.e., ...). Figure 2 (②) The winding T1 is connected to the first output terminal of the second inductor L2, the second terminal of the second inductor L2 is connected to the first terminal of the second resistor R2, and the second terminal of the second resistor R2 is connected to the first terminal of the target load (i.e., Figure 2 (③) Connect the second output terminal of winding T1 to the second terminal of the target load (i.e., Figure 2 (④) Connect.

[0054] It should be understood that the first input terminal of the winding T1 can be the first pin of the winding T1, the second input terminal of the winding T1 can be the second pin of the winding T1, the first output terminal of the winding T1 can be the third pin of the winding T1, and the second output terminal of the winding T1 can be the fourth pin of the winding T1.

[0055] It should also be understood that the first resistor R1 can be the primary winding resistance in the equivalent transformer T, the second resistor R2 can be the secondary winding resistance in the equivalent transformer T, the magnetizing resistance Rm can be the magnetizing resistance Rm in the equivalent transformer T, and the magnetizing inductance Lm can be the magnetizing inductance Lm in the equivalent transformer T.

[0056] It should be emphasized that the resistance values ​​of the first resistor R1, the second resistor R2, and the magnetizing resistor Rm, the inductance values ​​of the first inductor L1, the second inductor L2, and the magnetizing inductor Lm, and the turns ratio of the winding T1 can all be determined according to the actual transformer T used. This embodiment does not impose any restrictions on this.

[0057] Based on this, continue as follows Figure 2 As shown, an additional energy storage module can be added to this embodiment. The energy storage module can be a module for storing electricity, and in this embodiment, the energy storage module may include a first energy storage unit 1.

[0058] One end of the first energy storage unit 1 can be connected to the first end of an external power source (i.e., Figure 2 The first energy storage unit 1 is connected to the first end of the first inductor L1. Since there is a first resistor R1 in the equivalent case, the first energy storage unit 1 in this embodiment can be specifically connected to the first end of the first resistor R1.

[0059] It should be emphasized that when only the first energy storage unit 1 exists, the second end of the second resistor R2 is connected in the same way as in the traditional method.

[0060] The first energy storage unit 1 and the first inductor L1 are connected to form a first resonant circuit, which is used to boost the input voltage of the winding.

[0061] It should be noted that, since resonance can achieve voltage boost, this embodiment can form the aforementioned first resonant circuit together with the first inductor L1 in the transformer T through the additionally provided first energy storage unit 1. Therefore, in practical use, it is not necessary to rely solely on the winding T1 to achieve voltage boost; the first resonant circuit can also be used for voltage boosting, thereby increasing the peak output voltage.

[0062] It should also be noted that when the first energy storage unit 1 is set, the first resonant circuit can first boost the initial voltage output by the external power supply to serve as the boosted winding input voltage of the input winding T1. The winding T1 then boosts the boosted winding input voltage of the first energy storage unit 1 a second time, and finally transmits it to the target load for power supply.

[0063] This embodiment may additionally include an energy storage module, which may include a first energy storage unit 1. The first energy storage unit 1 and the first inductor L1 in the transformer T can form a first resonant circuit. Compared to the existing method of boosting voltage solely through the transformer T, this embodiment can also boost voltage through the first resonant circuit, thereby increasing the peak output voltage of the surgical device.

[0064] Furthermore, in order to realize the first resonant circuit, continue as follows Figure 2 As shown, in this embodiment, the first energy storage unit 1 includes: a first capacitor C1;

[0065] The first terminal of the first capacitor C1 is connected to an external power source, and the second terminal of the first capacitor C1 is connected to the first terminal of the first inductor L1.

[0066] It is understandable that the first terminal of the aforementioned first capacitor C1 can be connected to the first terminal of the external power supply (i.e., Figure 2 (①) Connection. In this embodiment, it is only necessary to make the first capacitor C1 resonate with the first inductor L1.

[0067] Meanwhile, in traditional methods, to obtain a higher voltage peak, a boost circuit is typically used before the input of transformer T. This method requires more components, resulting in higher costs and a larger final printed circuit board (PCB) area, making assembly more difficult. This embodiment, however, uses a first capacitor C1 to achieve voltage boost, eliminating the need for complex circuits like the boost circuit, reducing costs, and decreasing the PCB area, thus facilitating assembly.

[0068] Furthermore, to achieve the above objectives, this utility model embodiment also provides a surgical device with radio frequency energy function, referring to... Figure 3 , Figure 3 This is a schematic diagram of the second embodiment of the surgical device with radio frequency energy function proposed in this utility model.

[0069] like Figure 3 As shown, in this embodiment, the surgical device includes: an energy storage module and a transformer T with a first inductor L1, a second inductor L2, and a winding T1. The winding T1 is used to boost the winding input voltage to the winding output voltage. The energy storage module includes:

[0070] The second energy storage unit 2, the output terminal of the winding T1 is connected to the first terminal of the second inductor L2, the second terminal of the second inductor L2 is connected to the second energy storage unit 2, the second energy storage unit 2 and the second inductor L2 are connected to form a second resonant circuit, the second resonant circuit is used to boost the output voltage of the winding.

[0071] In this embodiment, refer to Figure 4 , Figure 4 This is a schematic diagram of the equivalent circuit of transformer T in the second embodiment of the surgical device with radio frequency energy function proposed in this utility model. It should be noted that in this embodiment, the equivalent circuit diagram of transformer T is different from... Figure 2 The same applies to this embodiment, so this embodiment will not elaborate further.

[0072] However, it is worth mentioning that this embodiment adds an energy storage module. This energy storage module can be used for storing electrical energy, and in this embodiment, it may include a second energy storage unit 2. One end of the second energy storage unit 2 can be connected to the second end of the second inductor L2. Since a second resistance R2 exists in an equivalent case, in this embodiment, the second energy storage unit 2 can specifically be connected to the second end of the second resistance R2. The other end of the second energy storage unit 2 can be connected to the target load (i.e.,...). Figure 4 (③) Connection

[0073] It should be emphasized that when a second energy storage unit 2 is present, the first end of the first resistor R1 is connected in the same way as in the traditional method, which will not be elaborated in this embodiment.

[0074] It should be noted that since resonance can achieve voltage boost, this embodiment can form the aforementioned second resonant circuit by additionally setting a second energy storage unit 2 together with the second inductor L2 in the transformer T. Therefore, in practical use, it is not necessary to rely solely on the winding T1 to achieve voltage boost; the second resonant circuit can also be used for voltage boosting, thereby increasing the peak output voltage.

[0075] It should also be noted that when the second energy storage unit 2 is set, the winding T1 can first boost the initial voltage output by the external power supply, that is, boost the winding input voltage once to obtain the winding output voltage. The second resonant circuit can then boost the winding output voltage a second time, and finally transmit it to the target load for power supply.

[0076] This embodiment can additionally include an energy storage module, which may include a second energy storage unit 2. The second energy storage unit 2 and the second inductor L2 in the transformer T can form a second resonant circuit. Compared to the existing method of boosting voltage solely through the transformer T, this embodiment can also boost voltage through the second resonant circuit, thereby increasing the peak output voltage of the surgical device.

[0077] Furthermore, in order to realize the second resonant circuit, continue as follows Figure 4 As shown, in this embodiment, the second energy storage unit 2 includes a second capacitor C2;

[0078] The first terminal of the second capacitor C2 is connected to the second terminal of the second inductor L2, and the second terminal of the second capacitor C2 is connected to the target load.

[0079] It should be understood that the second terminal of the aforementioned second capacitor C2 can be connected to the first terminal of the target load (i.e., Figure 2 (③) Connection. In this embodiment, it is only necessary to make the second capacitor C2 resonate with the second inductor L2.

[0080] In practical use, the second capacitor C2 can resonate with the second inductor L2 to form a second resonant circuit, which boosts the output voltage of the winding, thereby obtaining a higher peak output voltage.

[0081] Meanwhile, in traditional methods, to obtain a higher peak voltage, a boost circuit is typically used before the input of transformer T. This method requires more components, resulting in higher costs and a larger final printed circuit board (PCB) area, making assembly more difficult. This embodiment, however, uses a second capacitor C2 to achieve voltage boosting, eliminating the need for complex circuits like the boost circuit, reducing costs, and decreasing the PCB area, thus facilitating assembly.

[0082] Furthermore, in order to increase the peak voltage, continue as follows Figure 3 as well as Figure 4 As shown, in this embodiment, the energy storage module further includes:

[0083] The first energy storage unit 1 is connected to the first end of the first inductor L1, and the second end of the first inductor L1 is connected to the input end of the winding T1. The first energy storage unit 1 and the first inductor L1 are connected to form a first resonant circuit, which is used to boost the input voltage of the winding.

[0084] It should be emphasized that when only the first energy storage unit 1 exists, the second end of the second resistor R2 is connected in the same way as in the traditional method. When only the second energy storage unit 2 exists, the first end of the first resistor R1 is connected in the same way as in the traditional method. This embodiment will not elaborate on this. When both the first energy storage unit 1 and the second energy storage unit 2 exist, the connection can be made in the manner described above. This embodiment will not elaborate on this.

[0085] It should be noted that, since resonance can achieve voltage boost, this embodiment can form the aforementioned first resonant circuit by additionally setting the first energy storage unit 1 together with the first inductor L1 in the transformer T, and form the aforementioned second resonant circuit by additionally setting the second energy storage unit 2 together with the second inductor L2 in the transformer T. Therefore, in practical use, it is not necessary to rely solely on winding T1 to achieve voltage boost; the first and second resonant circuits can also be used for voltage boosting, thereby increasing the peak output voltage.

[0086] It should also be noted that when both the first energy storage unit 1 and the second energy storage unit 2 are set, the first resonant circuit can first boost the initial voltage output by the external power supply to obtain the winding input voltage. The winding T1 then boosts the winding input voltage after the first resonant resistor boosts it a second time to obtain the winding output voltage. The second resonant circuit can then boost the winding output voltage a third time, and finally transmit it to the target load for power supply.

[0087] It should be emphasized that the choice between setting the first energy storage unit 1 or setting the second energy storage unit 2 can be made according to the actual situation, and this embodiment does not impose any restrictions on this.

[0088] Furthermore, the first energy storage unit 1 includes: a first capacitor C1;

[0089] The first terminal of the first capacitor C1 is connected to an external power source, and the second terminal of the first capacitor C1 is connected to the first terminal of the first inductor L1.

[0090] It should be emphasized that the connection method of the first energy storage unit 1 described above in this embodiment can refer to the first embodiment described above, and this embodiment will not elaborate on it.

[0091] Reference Figure 5 , Figure 5 This is a structural block diagram of a third embodiment of a surgical device with radio frequency energy function proposed in this utility model.

[0092] To further increase the peak output voltage, such as Figure 5 As shown, in this embodiment, the surgical device further includes: a resonant module;

[0093] The resonant module is connected to the second energy storage unit 2, and the resonant module is used to further boost the winding output voltage after the second resonant circuit has been boosted.

[0094] It should be noted that a resonant circuit can also be provided in the above-mentioned resonant module. In this embodiment, when the second capacitor C2 is not provided, the first end of the above-mentioned resonant module can be connected to the output end of the transformer T, that is, connected to the second end of the second resistor R2 and the second output end of the winding T1, and the second end of the resonant module can be connected to the target load; when the second capacitor C2 is provided, the first end of the above-mentioned resonant module can be connected to the second energy storage unit 2, that is, connected to the second end of the second capacitor C2 and also connected to the second output end of the winding T1, and the second end of the resonant module is then connected to the target load.

[0095] In practical use, when the second energy storage unit 2 is not set, the resonant module can boost the output voltage of the winding after the winding T1 is boosted, and then transmit the boosted output voltage of the winding to the target load for power supply; when the second energy storage unit 2 is set, the resonant module can boost the output voltage of the winding after the second resonant circuit is boosted, and then transmit the boosted output voltage of the winding to the target load for power supply.

[0096] Furthermore, continue as Figure 5 As shown, in this embodiment, the resonant module includes: a first resonant unit 31 and a second resonant unit 32;

[0097] The first resonant unit 31 is connected to the second energy storage unit 2 and the second resonant unit 32 respectively. The first resonant unit 31 is used to transmit the winding output voltage after the second resonant circuit is boosted to the second resonant unit 32.

[0098] The second resonant unit 32 is used to boost the winding output voltage of the second resonant circuit after it has been boosted.

[0099] The first resonant unit 31 is also used to boost the winding output voltage of the second resonant unit 32 after it has been boosted.

[0100] It should be noted that the first resonant unit 31 can be a unit formed by series resonance, and the second resonant unit 32 can be a unit formed by parallel resonance. Both can be composed of a capacitor and an inductor, and may also include other components. This embodiment does not limit this.

[0101] It is understandable that the aforementioned first resonant unit 31 can also be connected to one end of the target load (i.e., Figure 5 (③) is connected, and the second resonant unit 32 can also be connected to the other end of the target load (i.e. Figure 5 (④) Connect.

[0102] It is also understood that when a second energy storage unit 2 is provided, the first resonant unit 31 can be connected to the second terminal of the second capacitor C2; when a second energy storage unit 2 is not provided, the first resonant unit 31 can be connected to the second terminal of the second resistor R2. Furthermore... Figure 5 The transformer T shown is in the non-equivalent case. That is, the first input terminal of transformer T (i.e., the first pin of transformer T) is the first terminal of the first resistor R1 in the equivalent case, the second input terminal of transformer T (i.e., the second pin of transformer T) is the second input terminal of winding T1 in the equivalent case, the first output terminal of transformer T (i.e., the third pin of transformer T) is the second terminal of the second resistor R2 in the equivalent case, and the second output terminal of transformer T (i.e., the fourth pin of transformer T) is the second output terminal of winding T1 in the equivalent case. Therefore, the above-mentioned components such as the second resistor R2 are not shown, but equivalent substitutions can be made. This embodiment will not elaborate on this.

[0103] In practical use, the first resonant unit 31 can transmit the winding output voltage after the transformer T is stepped up or the winding output voltage after the second resonant circuit is stepped up to the second resonant unit 32 for step-up. After the winding output voltage after the second resonant unit 32 is stepped up, it is finally transmitted to the target load for power supply.

[0104] Furthermore, the first resonant unit 31 includes: a third inductor L3 and a third capacitor C3;

[0105] The first end of the third inductor L3 is connected to the second energy storage unit 2, the second end of the third inductor L3 is connected to the first end of the third capacitor C3 and the second resonant unit 32, and the second end of the third capacitor C3 is connected to the target load.

[0106] It should be understood that the first terminal of the third inductor L3 can be connected to the second terminal of the second capacitor C2 or the second terminal of the second resistor R2.

[0107] In practical use, the third inductor L3 and the third capacitor C3 form a series resonance, which can boost the output voltage of the winding.

[0108] Furthermore, the second resonant unit 32 includes: a fourth inductor L4 and a fourth capacitor C4;

[0109] The first end of the fourth inductor L4 is connected to the second end of the third inductor L3 and the first end of the fourth capacitor C4, respectively. The second end of the fourth inductor L4 is connected to the output end of the winding T1, the second end of the second capacitor C2 and the target load, respectively.

[0110] It should be noted that the second terminal of the fourth inductor L4 and the second terminal of the fourth capacitor C4 can be connected to the second output terminal of the winding T1, and can also be connected to the second terminal of the target load.

[0111] In practical use, the fourth inductor L4 and the fourth capacitor C4 form a parallel resonance, which can boost the output voltage of the winding.

[0112] It should be emphasized that when only transformer T and the above-mentioned resonant module are set, without setting the first energy storage unit 1 and the second energy storage unit 2, transformer T can first boost the received initial voltage, and the resonant module can boost it again. However, since the resonant module uses an LC resonant network for voltage amplification, it will reduce the input impedance of the LC resonant network. At this time, the second leakage inductance of transformer T and the input impedance of the LC resonant network form a series voltage divider model of the circuit. Therefore, in this embodiment, the second energy storage unit 2 can resonate with the second leakage inductance to form a leakage inductance resonant compensation circuit, which further improves the peak output voltage.

[0113] To facilitate understanding, the following example illustrates this: If in this embodiment, the first resistor R1 of transformer T has a resistance of 0.1Ω, the first inductor L1 has an inductance of 0.5e-6H, the second resistor R2 has a resistance of 0.1Ω, the second inductor L2 has an inductance of 0.5e-6H, and the turns ratio of winding T1 is 1:3, then theoretically, transformer T can achieve a 3x amplification.

[0114] If the above resonant module can theoretically achieve 10 times amplification when it is built, when the initial input voltage frequency is a 1.7MHz sine wave and the peak voltage is 216V, for the resonant module, ignoring the oscillation part, the peak voltage of the winding output voltage obtained after boosting can be about 2124V, with an amplification factor of 9.83 times, which is about 10 times.

[0115] When the first energy storage unit 1 and the second energy storage unit 2 in this embodiment are not set, and only the transformer T is connected in series with the resonant module, based on the above example, if the resistance of the target load is 1000Ω, according to theoretical analysis, the transformer T amplifies by 3 times and the resonant module amplifies by 10 times, theoretically the amplification factor is 30 times. However, according to experiments, if the peak voltage of the initial voltage is 80V, the peak voltage obtained by the target load is 414.5V, which is about 5.18 times, which does not match the theoretical value. This is because the leakage inductance in the transformer T is 0.5e-6H. At high frequencies, this inductance will be connected in series with the equivalent input impedance of the LC resonant network to divide the voltage, resulting in the amplification factor not matching the theory.

[0116] In this embodiment, based on the principle of series resonance, a first capacitor C1 is added to the input terminal of transformer T, and a second capacitor C2 is added to the output terminal of transformer T, with the capacitance value of both being 1.75e-8F. According to experiments, if the peak voltage of the initial voltage is 80V, the peak voltage obtained by the target load is 2124V, which is approximately 26.55 times, close to the theoretical amplification factor of 30. The reason for the still existing difference may be that the leakage resistance loss of transformer T cannot be offset, and transformer T itself also has losses such as eddy currents and hysteresis.

[0117] In addition, to achieve the above objectives, this utility model embodiment also provides a surgical system, which may include surgical equipment with radio frequency energy function as described above.
