Description

Technical Field

[0001] This application relates to the field of voltage control technology, and in particular to a pulse generation circuit, device and method. Background Technology

[0002] In recent years, pulsed electric fields have driven the development of irreversible electroporation technology in bioelectromagnetics. By applying a high-voltage pulsed electric field of a certain strength and pulse width to the tumor lesion area, irreversible electroporation is induced in the tumor cell membrane within the effective electric field coverage area, leading to cell death and achieving the purpose of ablation of tumors.

[0003] Typically, pulse generation circuits in existing technologies can only generate high-voltage narrow pulses. These high-voltage narrow pulses can only create a wide range of perforation areas on the cell membrane. However, the high-voltage narrow pulses cannot further expand the micropore area within the perforation area, thus failing to increase the ratio of micropore area to perforation area. Consequently, the effect of micropores on cell ablation is reduced, affecting the effect of irreversible perforation. Summary of the Invention

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0039] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0040] As described in the background art, high-voltage narrow pulses can generate a wide range and a large number of micropores on the cell membrane. A perforation includes multiple adjacent micropores, and the perforation area includes the cell membrane covered by multiple micropores and the cell membrane between multiple micropores. Therefore, the micropores generated by high-voltage narrow pulses can enable the cell membrane to produce more perforations and a larger perforation area.

[0041] In related technologies, the development of micropore area is proportional to the square of the pulse width applied to the cell membrane. Therefore, increasing the pulse width can expand the micropore area.

[0042] This leads to the following problems: increasing the width of the high-voltage pulse will increase the energy of the pulse, thereby increasing the output power of the pulse generation circuit.

[0043] Therefore, in order to reduce the pulse energy of wide pulses, it is necessary to reduce the voltage of wide pulses, that is, a pulse generation circuit that can coordinate the generation of high-voltage narrow pulses and low-voltage wide pulses is needed.

[0044] like Figure 1a As shown, the pulse generation circuit 100 of this embodiment includes:

[0045] The pulse generation circuit 100 includes: a high-voltage pulse module 101, a low-voltage pulse module 103, and a coordination pulse module 102. One end of the high-voltage pulse module 101 is connected to a high-voltage power supply, and the other end of the high-voltage pulse module 101 is connected to the coordination pulse module 102. One end of the low-voltage pulse module 103 is connected to a low-voltage power supply, and the other end of the low-voltage pulse module 103 is connected to the coordination pulse module 102.

[0046] The high-voltage pulse module 101 is configured to receive a high-voltage pulse control signal, generate a high-voltage pulse according to the high-voltage pulse control signal, and send the high-voltage pulse to the coordination pulse module 102;

[0047] The low-voltage pulse module 103 is configured to receive a low-voltage pulse control signal, generate a low-voltage pulse according to the low-voltage pulse control signal, and send the low-voltage pulse to the coordination pulse module 102.

[0048] The coordination pulse module 102 is configured to receive a coordination pulse control signal, control the high voltage pulse and / or the low voltage pulse to form a coordination pulse according to the coordination pulse control signal, and output the coordination pulse.

[0049] In specific implementation, the high-voltage pulse module 101 converts the high-voltage AC power from the high-voltage power supply into controllable high-voltage pulses, the low-voltage pulse module 103 converts the low-voltage AC power from the low-voltage power supply into controllable low-voltage pulses, and the coordination pulse module 102 converts the high-voltage pulses and / or low-voltage pulses into controllable coordination pulses.

[0050] Optionally, the high-voltage pulse can be a high-voltage narrow pulse, and the low-voltage pulse can be a low-voltage wide pulse. The coordinated pulse can be a mixed pulse of high-voltage narrow pulse and low-voltage wide pulse. In this way, by using a high-voltage narrow pulse to generate a wide range and a large number of micropores on the cell membrane, the cell membrane will produce more perforations and a larger perforation area. Then, by applying a low-voltage narrow pulse, the cell membrane perforations can be further expanded, inducing irreversible electroporation, thereby reducing the energy required for irreversible electroporation and expanding the range of irreversible electroporation on the cell membrane.

[0051] Understandably, the coordination pulse can control the proportion and combination of high-voltage narrow pulses and low-voltage wide pulses, for example, Figure 1e As shown, within time t2-t3, the output pulse width is 200ms and the voltage amplitude is 20kV high-voltage narrow pulse. Within time t6-t7, the output pulse width is 500ms and the voltage amplitude is 5kV low-voltage wide pulse. At this time, the energy proportion of the low-voltage wide pulse is less than that of the high-voltage narrow pulse, and the high-voltage pulse is applied earlier than the low-voltage pulse.

[0052] Through the above scheme, the high-voltage pulse sent by the high-voltage pulse module 101 and the low-voltage pulse sent by the low-voltage pulse module 103 are controlled by the coordinated pulse module 102 to form a coordinated pulse including high-voltage pulse and / or low-voltage pulse. In this way, the generation of high-voltage pulse and / or low-voltage pulse can be completed by a single pulse generation circuit without the need for additional equipment. The coordinated pulse output by the pulse generation circuit 100 includes both high-voltage pulse and low-voltage pulse, which expands the voltage range of the output pulse of the pulse generation circuit 100. This allows the pulse generation device to achieve the effect of high-voltage pulse and low-voltage pulse simultaneously. Furthermore, the proportion and combination of high-voltage pulse and low-voltage pulse output by the pulse generation device can be adjusted by the coordinated pulse control signal, ensuring the flexibility of the coordinated pulse output by the pulse generation circuit 100.

[0053] In some embodiments, the high-voltage pulse includes at least one of the following: a positive high-voltage pulse, a negative high-voltage pulse, and a bipolar high-voltage pulse.

[0054] In practice, a positive high-voltage pulse refers to a high-voltage pulse with a positive voltage amplitude, a negative high-voltage pulse refers to a high-voltage pulse with a negative voltage amplitude, and a bipolar high-voltage pulse refers to a high-voltage pulse that includes both positive and negative voltage amplitudes.

[0055] This enriches the variety of high-voltage pulses in the coordinated pulses output by the pulse generation circuit, thus expanding the application range of the pulse generation circuit.

[0056] In some embodiments, the low-voltage pulse includes at least one of the following: a positive low-voltage pulse, a negative low-voltage pulse, and a bipolar low-voltage pulse.

[0057] In practice, a positive low-voltage pulse refers to a low-voltage pulse with a positive voltage amplitude, a negative low-voltage pulse refers to a low-voltage pulse with a negative voltage amplitude, and a bipolar low-voltage pulse refers to a low-voltage pulse that includes both positive and negative voltage amplitudes.

[0058] This enriches the variety of low-voltage pulses in the coordinated pulses output by the pulse generation circuit, thus expanding the application range of the pulse generation circuit.

[0059] In some embodiments, such as Figure 1b As shown, the high-voltage pulse module 101 includes:

[0063] The high-voltage switch unit 1014 includes a first high-voltage switch 1141 and a second high-voltage switch 1142, wherein the first high-voltage switch 1141 and the second high-voltage switch 1142 are connected in series, one end of the first high-voltage switch 1141 is connected to the third high-voltage lead, and the other end of the first high-voltage switch 1141 is connected to the second high-voltage switch 1142 and the coordination pulse module.

It is configured to control the first high-voltage switch 1141 and the second high-voltage switch 1142 to be turned on or off according to the high-voltage pulse control signal.

[0064] In specific implementation, the high-voltage rectifier bridge unit 1011 refers to a converter capable of rectifying high-voltage AC power into high-voltage DC power. In this embodiment, the preferred high-voltage rectifier bridge unit 1011 can be a bridge-type converter capable of rectifying high-voltage AC power into high-voltage DC power. The high-voltage DC power transmitted by the high-voltage rectifier bridge unit 1011 can charge the high-voltage half-bridge capacitor unit 1013. The charging process of the high-voltage half-bridge capacitor unit 1013 can be controlled by adjusting the switching signal of the rectifier bridge unit.

[0065] The high-voltage half-bridge resistor unit 1011 can provide a discharge path for the electrical energy on the high-voltage half-bridge capacitor unit 1013, and can also provide protection when the high-voltage half-bridge capacitor unit 1013 is charging.

[0066] The high-voltage half-bridge capacitor unit 1013 can provide voltage regulation for the high-voltage pulses sent by the high-voltage pulse unit, ensuring that the voltage of the high-voltage pulse remains constant when it is sent.

[0067] Optionally, the resistance value of the first high-voltage resistor 1121 in the high-voltage half-bridge resistor unit 1011 can be equal to the resistance value of the second high-voltage resistor 1122, and the capacitance value of the first high-voltage capacitor 1131 in the high-voltage half-bridge capacitor unit 1013 can be equal to the capacitance value of the second high-voltage capacitor 1132.

[0074] In specific implementation, the low-voltage rectifier bridge unit 1031 refers to a converter capable of rectifying low-voltage AC power into low-voltage DC power. In this embodiment, the preferred low-voltage rectifier bridge unit 1031 can be a bridge-type converter capable of rectifying low-voltage AC power into low-voltage DC power. The low-voltage DC power transmitted by the low-voltage rectifier bridge unit 1031 can charge the low-voltage half-bridge capacitor unit 1033.

[0076] The low-voltage half-bridge capacitor unit 1033 can provide voltage regulation for the low-voltage pulses sent by the low-voltage pulse unit, ensuring that the voltage of the low-voltage pulse remains constant when it is sent.

[0078] In this way, the low-voltage pulse module 103 can send low-voltage pulses with stable pulse voltage to the coordination pulse module 103.

[0079] In some embodiments, such as Figure 1d As shown, the coordination pulse module 102 includes:

[0080] The coordination switching unit includes a first switching terminal 1021, a second switching terminal 1022, and a third switching terminal 1023.

[0081] In specific implementation, the single-pole double-throw switch 1024 refers to a switch that can switch between the first switch terminal 1021 and the second switch terminal 1022. In this embodiment, the preferred single-pole double-throw switch 1024 can be a switch that can switch between the first switch terminal 1021 and the second switch terminal 1022, which is controlled by a coordinated pulse control signal.

[0082] When the first switch terminal 1021 and the third switch terminal 1023 are turned on, they provide the circuit basis for the high-voltage pulse unit to send high-voltage pulses to the coordination control unit; when the second switch terminal 1022 and the third switch terminal 1023 are turned on, they provide the circuit basis for the low-voltage pulse unit to send low-voltage pulses to the coordination control unit.

[0084] In this way, the coordinated pulse output by the pulse generation circuit includes both high-voltage and low-voltage pulses, expanding the voltage range of the output pulses of the pulse generation circuit. This allows the pulse generation device to simultaneously achieve the effects of high-voltage and low-voltage pulses. Furthermore, the proportion and combination of high-voltage and low-voltage pulses output by the pulse generation device can be adjusted through the coordinated pulse control signal, ensuring the flexibility of the coordinated pulse output by the pulse generation circuit.

[0093] Step 301: Receive the high-voltage pulse control signal through the high-voltage pulse module, generate a high-voltage pulse according to the high-voltage pulse control signal, and send the high-voltage pulse to the coordination pulse module.

[0094] In this step, the high-voltage pulse control signal refers to the signal that can control the conversion of high-voltage alternating current into high-voltage pulses. In this embodiment, the preferred high-voltage pulse control signal may include a rectifier bridge control signal that controls the conversion of high-voltage alternating current into high-voltage direct current and a switch control signal that controls the conversion of high-voltage direct current into high-voltage pulses.

[0095] In this way, the high-voltage pulse can send a stable high-voltage pulse to the coordination pulse module, thereby providing a pulse basis for the generation of the coordination pulse.

[0096] Step 302: Receive a low-voltage pulse control signal using the low-voltage pulse module, generate a low-voltage pulse based on the low-voltage pulse control signal, and send the low-voltage pulse to the coordination pulse module.

[0097] In this step, the low-voltage pulse control signal refers to a signal that can control the conversion of low-voltage AC power into low-voltage pulses. In this embodiment, the preferred low-voltage pulse control signal may include a rectifier bridge control signal that controls the conversion of low-voltage AC power into low-voltage DC power and a switch control signal that controls the conversion of low-voltage DC power into low-voltage pulses.

[0098] In this way, the low-voltage pulse can send a low-voltage pulse with stable pulse voltage to the coordination pulse module, thereby providing a pulse basis for the generation of the coordination pulse.

[0099] Step 303: The coordinated pulse module receives the coordinated pulse control signal, controls the high voltage pulse and / or the low voltage pulse to form a coordinated pulse according to the coordinated pulse control signal, and outputs the coordinated pulse.

[0100] In this step, the coordination pulse control signal refers to the signal that can control the high voltage pulse and / or the low voltage pulse to form a coordination pulse. In this embodiment, the preferred coordination pulse signal can be a switching signal that controls the connection between the high voltage pulse module and the low voltage pulse module and the coordination pulse module.

[0101] For example, at time t2, the coordination pulse control signal controls the coordination pulse output by the coordination pulse module to be a high-voltage pulse; at time t6, the coordination pulse control signal controls the coordination pulse output by the coordination pulse module to be a low-voltage pulse.

[0102] In this way, the ratio and combination of high-voltage and low-voltage pulses output by the pulse generation device can be adjusted by the coordinated pulse control signal, ensuring the flexibility of the pulse generation circuit in outputting coordinated pulses.

[0103] The above scheme uses a coordinated pulse module to control the high-voltage pulses sent by the high-voltage pulse module and the low-voltage pulses sent by the low-voltage pulse module to form a coordinated pulse that includes both high-voltage and / or low-voltage pulses. Thus, a single pulse generation circuit can generate both high-voltage and / or low-voltage pulses without the need for additional equipment. The coordinated pulse output by the pulse generation circuit includes both high-voltage and low-voltage pulses, expanding the voltage range of the output pulses and enabling the pulse generation device to simultaneously achieve the effects of both high-voltage and low-voltage pulses. Furthermore, the proportion and combination of high-voltage and low-voltage pulses output by the pulse generation device can be adjusted via a coordinated pulse control signal, ensuring the flexibility of the coordinated pulse output by the pulse generation circuit.

[0104] In some embodiments, generating a high-voltage pulse based on the high-voltage pulse control signal includes:

[0105] The high-voltage rectifier bridge unit converts the high-voltage AC power output from the high-voltage power supply into high-voltage DC power according to the high-voltage pulse control signal.

[0106] The high-voltage half-bridge capacitor unit is used to charge the capacitors according to the high-voltage DC power so that the voltages on the first high-voltage capacitor and the second high-voltage capacitor are in a first constant state.

[0107] The high-voltage switching unit controls the first high-voltage switch and the second high-voltage switch to be turned on or off according to the high-voltage pulse control signal, so that the high-voltage pulse module outputs the high-voltage pulse.

[0108] In the above scheme, the rectifier bridge unit is controlled by the rectifier bridge control signal in the high-voltage pulse control signal, which controls the conversion of high-voltage AC to high-voltage DC. The charging process of the high-voltage half-bridge capacitor unit can be controlled by adjusting the rectifier bridge control signal, and the pre-set charging voltage in the rectifier bridge control signal can be the voltage value of the high-voltage pulse. The first constant state refers to the state in which the voltage values ​​of the first high-voltage capacitor and the second high-voltage capacitor remain unchanged. In this embodiment, the preferred first constant state is a state in which the voltage values ​​of the first high-voltage capacitor and the second high-voltage capacitor are equal to the voltage value of the high-voltage pulse.

[0109] After the charging process of the high-voltage half-bridge capacitor unit is completed, the high-voltage switching unit is controlled by the switching signal that converts the high-voltage DC power into a high-voltage pulse in the high-voltage pulse control signal. The conduction time corresponding to the first high-voltage switch can be the pulse width of the positive high-voltage pulse, and the conduction time corresponding to the second high-voltage switch can be the pulse width of the negative high-voltage pulse.

[0110] For example, if the first high-voltage switch is turned on between times t2 and t3, then the pulse width of the positive high-voltage pulse is τ. H1 = t3-t2; between t4-t5, the second high-voltage switch is turned on, then the pulse width of the negative high-voltage pulse is τ. H2 = t5-t4.

[0111] Through the above scheme, the high-voltage pulse can send a stable high-voltage pulse to the coordination pulse module, thereby providing a pulse basis for the generation of the coordination pulse.

[0112] In some embodiments, generating a low-voltage pulse based on the low-voltage pulse control signal includes:

[0113] The low-voltage rectifier bridge unit converts the low-voltage AC power output from the low-voltage power supply into low-voltage DC power according to the low-voltage pulse control signal.

[0114] The low-voltage half-bridge capacitor unit is used to charge the capacitors according to the low-voltage DC power so that the voltage on the first low-voltage capacitor and the second low-voltage capacitor is in a second constant state.

[0115] The low-voltage switching unit controls the first low-voltage switch and the second low-voltage switch to be turned on or off according to the low-voltage pulse control signal, so that the low-voltage pulse module outputs the low-voltage pulse.

[0116] In the above scheme, the rectifier bridge unit is controlled by the rectifier bridge control signal in the low-voltage pulse control signal, which controls the conversion of low-voltage AC to low-voltage DC. The charging process of the low-voltage half-bridge capacitor unit can be controlled by adjusting the rectifier bridge control signal, and the pre-set charging voltage in the rectifier bridge control signal can be the voltage value of the low-voltage pulse. The first constant state refers to the state in which the voltage values ​​of the first low-voltage capacitor and the second low-voltage capacitor remain unchanged. In this embodiment, the preferred first constant state is the state in which the voltage values ​​of the first low-voltage capacitor and the second low-voltage capacitor are equal to the voltage value of the low-voltage pulse.

[0117] After the charging process of the low-voltage half-bridge capacitor unit is completed, the low-voltage switching unit is controlled by the switching signal in the low-voltage pulse control signal that converts the low-voltage DC power into a low-voltage pulse. The conduction time corresponding to the first low-voltage switch can be the pulse width of the positive low-voltage pulse, and the conduction time corresponding to the second low-voltage switch can be the pulse width of the negative low-voltage pulse.

[0118] For example, if the first low-voltage switch is turned on between times t2 and t3, then the pulse width of the positive low-voltage pulse is τ. H1 = t3-t2; between t4-t5, the second low-voltage switch is turned on, then the pulse width of the negative low-voltage pulse is τ. H2 = t5-t4.

[0119] Through the above scheme, the low-voltage pulse can send a low-voltage pulse with stable pulse voltage to the coordination pulse module, thereby providing a pulse basis for the generation of the coordination pulse.

[0120] In some embodiments, generating a coordination pulse based on the coordination pulse control signal includes:

[0121] Obtain the switching time point in the coordinated pulse control signal;

[0122] The single-pole double-throw switch is controlled to switch from the first switch terminal to the second switch terminal or from the second switch terminal to the first switch terminal according to the switching time point.

[0123] In the above scheme, the switching time point refers to the time point when the high voltage pulse is converted to the low voltage pulse or the time point when the low voltage pulse is converted to the high voltage pulse. In this embodiment, the preferred switching time point can be the switching time point of a single-pole double-throw switch.

[0124] It is understandable that the pulse width of the low-voltage pulse in the coordination pulse is at least twice the pulse width of the high-voltage pulse, and the state of the single-pole double-throw switch can be neither at the first switch terminal nor the second switch terminal, that is, the single-pole double-throw switch is in the off state. The single-pole double-throw switch in the off state corresponds to the pulse signal between the high-voltage pulse and the low-voltage pulse in the coordination pulse.

[0125] For example, time t6 is the switching time point, at which time the single-pole double-throw switch switches from the first switch terminal to the second switch terminal.

[0126] Through the above scheme, the proportion and combination of high-voltage pulses and low-voltage pulses output by the pulse generation device can be adjusted by the coordinated pulse control signal, ensuring the flexibility of the pulse generation circuit in outputting coordinated pulses.

[0130] In this step, the high-voltage pulse control signal refers to the signal that can control the conversion of high-voltage alternating current into high-voltage pulses. In this embodiment, the preferred high-voltage pulse control signal may include a rectifier bridge control signal that controls the conversion of high-voltage alternating current into high-voltage direct current and a switch control signal that controls the conversion of high-voltage direct current into high-voltage pulses.

[0131] The low-voltage pulse control signal refers to a signal that can control the conversion of low-voltage alternating current into low-voltage pulses. In this embodiment, the preferred low-voltage pulse control signal may include a rectifier bridge control signal that controls the conversion of low-voltage alternating current into low-voltage direct current and a switch control signal that controls the conversion of low-voltage direct current into low-voltage pulses.

[0132] The coordination pulse control signal refers to the signal that can control the high voltage pulse and / or the low voltage pulse to form a coordination pulse. In this embodiment, the preferred coordination pulse signal can be a switching signal that controls the connection between the high voltage pulse module and the low voltage pulse module and the coordination pulse module.

[0133] In this way, low-voltage pulses can send stable low-voltage pulses to the coordination pulse module, thus providing a pulse basis for the generation of coordination pulses; high-voltage pulses can send stable high-voltage pulses to the coordination pulse module, thus providing a pulse basis for the generation of coordination pulses; the ratio and combination of high-voltage pulses and low-voltage pulses output by the pulse generation device can be adjusted by the coordination pulse control signal, ensuring the flexibility of the pulse generation circuit in outputting coordination pulses.

[0134] Step 402: The pulse generation circuit outputs a coordinated pulse based on the high-voltage pulse control signal, the low-voltage pulse control signal, and the coordinated pulse control signal.

[0135] In this step, the coordination pulse refers to a pulse that includes both high-voltage and / or low-voltage pulses.

[0136] In this way, the coordinated pulse output by the pulse generating device includes both high-voltage and low-voltage pulses, expanding the voltage range of the pulse output by the pulse generating circuit, enabling the pulse generating device to simultaneously achieve the effects of high-voltage and low-voltage pulses.
