Description

Technical Field

[0001] The present invention relates to the technical field of shock wave power supplies, and particularly relates to a shock wave power supply and a charging and discharging method. Background Art

[0002] The liquid-electric shock wave technology has been widely applied in the treatment fields such as extracorporeal shock wave lithotripsy for kidneys, peripheral vascular calcification, assisting coronary artery stent implantation, and relieving pain (such as muscle). The existing liquid-electric shock wave system includes an energy storage capacitor arranged in a high-voltage pulse power supply and a shock wave electrode electrically connected to the energy storage capacitor. The energy storage capacitor charges the shock wave electrode, and when the voltage at both ends of the shock wave electrode reaches the breakdown voltage of the shock wave electrode, the shock wave electrode discharges and breaks down to release shock waves.

[0003] In order to increase the energy of the shock wave, sometimes it is necessary to discharge multiple shock wave electrodes simultaneously.

[0004] Since the single-channel power supply of the existing liquid-electric shock wave system can only discharge a single shock wave electrode to generate shock waves, the existing solutions all adopt a single-channel power supply in series with multiple shock wave electrodes.

[0005] The traditional shock wave power supply uses common microcontrollers on the market such as existing DSP (Digital Signal Processing) chips, MCUs (Microcontroller Units), and FPGAs (Field Programmable Gate Arrays) to control ACDC or DCDC boost modules to charge the energy storage capacitor until a relatively high voltage is reached at both ends of the energy storage capacitor, and then the energy in the energy storage capacitor is released to the shock wave generating device (usually a pair of shock wave electrodes immersed in a liquid medium) by a control switching component, and the shock wave generating device generates an arc under high voltage and then emits shock waves to achieve.

[0006] A schematic diagram of a common shock wave power supply is as Figure 1 shown. The shock wave systems currently used in the coronary field are all as Figure 1 shown, and a single-channel power supply discharges a single shock wave electrode to generate shock waves. In the figure, 101 is a boost module, 102 is a control module, 100 is a high-voltage pulse power supply, 200 is a connection component, 300 is a shock wave catheter, and 301 and 302 are both shock wave electrodes.

[0007] When multiple shock wave electrodes need to discharge simultaneously, each shock wave electrode needs to be connected in series to the boost module interface for discharging.

[0008] Currently, both domestic medical device manufacturers and shockwave adopt the technical solution of connecting multiple shockwave electrodes in series with a single power supply.

[0009] Before breakdown, the shockwave electrode is equivalent to a capacitor, and after breakdown by discharge, it is equivalent to an inductor. Taking the discharge breakdown of two series-connected shockwave electrodes as an example, as Figure 2 shown in the circuit schematic diagram. Since the parameters between the two shockwave electrodes cannot be made absolutely the same, during the working process, one of the shockwave electrodes will inevitably break down and discharge first, and then the other shockwave electrode will quickly break down and discharge. Since the time interval between the breakdown discharges of the two shockwave electrodes is very short, it is approximately equivalent to the two shockwave electrodes breaking down simultaneously to generate shockwaves. The shockwaves generated by the two shockwave electrodes are superimposed on each other to increase the shockwave energy.

[0010] Disadvantages of the prior art:

[0011] The two shockwave electrodes can only discharge together. If the requirement is that two shockwave electrodes or multiple shockwave electrodes do not discharge together (for example, discharge sequentially), or if the requirement is to control the discharge of one shockwave electrode or several shockwave electrodes together according to the magnitude of the required shockwave energy (for different application scenario requirements, different shockwave energies need to be output), the existing technical solutions can only use multiple power supplies to discharge two or more shockwave electrodes. Still taking two shockwave electrodes as an example, the existing technical solutions need to set up two boost modules, as Figure 3 shown. Obviously, this will lead to a complex circuit and a doubling of the equipment cost.

[0012] In addition, the traditional shockwave generation circuit needs to charge and discharge the energy storage capacitor. Limited by this, the highest frequency of the shockwave is limited to about 5 Hz. The existing technical solutions cannot increase the frequency of the shockwave, which is still about 5 Hz.

[0013] The frequency of the shockwave refers to the number of shockwaves released per unit time. Summary of the Invention

[0048] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0049] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0050] As Figure 4 shown, the present invention provides a shock wave power supply, including a boost circuit, at least two energy storage units, and at least two discharge units. All the energy storage units and the boost circuit are electrically connected to a first single circuit; one end of any one discharge unit is electrically connected to one end of any one energy storage unit through a first connection circuit, and the other end of any one discharge unit is electrically connected to the other end of any one energy storage unit through a second connection circuit; any one discharge unit is electrically connected to at least one electrode switch-type component in the same single circuit.

[0051] The embodiments of the present invention can complete the combined discharge of any one discharge unit according to different shock wave energy requirements. For example, a single discharge unit discharges, at least two discharge units discharge sequentially according to the preset discharge timing requirements, at least two discharge units discharge together, or even a complex combined discharge method of first at least two discharge units discharge and then a single discharge unit discharges. It can not only adjust the energy magnitude of the shock wave according to the number of discharge units discharging together, but also adjust the generation frequency of the shock wave according to the requirements, so as to adapt to the shock wave energy requirements in various application scenarios such as cardiac vascular calcification treatment and peripheral vascular calcification treatment. The energy level and frequency can be adjusted according to the different degrees of calcification, so as to just solve the calcification problem without affecting the integrity of the tissues around the calcification lesion.

[0052] Meanwhile, the boost circuit in the embodiments of the present invention can charge all energy storage capacitors simultaneously. The present invention realizes high-efficiency energy transmission and unified energy distribution, ensuring that each energy storage unit in the system can quickly and evenly reach the required energy level. This design not only improves the convenience and reliability of the charging process but also allows for more precise control of the charging state of the entire system, enabling the subsequent discharge process to be more stable and predictable, ultimately enhancing the overall performance of the shock wave power supply and the energy consistency of the output shock wave.

[0053] It should be noted that the electrical connection referred to herein means a way of connecting electrical devices or components to each other through wires, cables, or other types of electrical wires to achieve current transmission and signal exchange. It can be permanent or detachable, depending on the type of connector used and the application scenario.

[0054] At least one of the first connection circuit and the second connection circuit is provided with at least one electrode switch-type component. Such a design not only improves the flexibility of the system, allowing for individual or combined discharge of different discharge units, but also enables adjustment of the energy magnitude and generation frequency of the shock wave according to actual needs, thus better adapting to diverse medical application scenarios. In addition, by controlling the connection timing of the electrode switches, high-frequency shock waves can be generated within a very short time, significantly improving the treatment effect.

[0055] It should be noted that Figure 4 In the embodiments of the present invention, it includes the first energy storage capacitor C1, the second energy storage capacitor C2... and the nth energy storage capacitor Cn. The series connection of the above-mentioned multiple energy storage capacitors means that one end of the first energy storage capacitor C1 is connected to the positive electrode of the boost circuit, the other end of the first energy storage capacitor C1 is connected to one end of the second energy storage capacitor C2, the other end of the second energy storage capacitor C2 is connected to one end of the subsequent energy storage capacitor, and so on until the other end of the nth energy storage capacitor is connected to the negative electrode of the boost circuit. Among them, the value range of n is a natural number greater than or equal to 3.

[0056] In the embodiments of the present invention, it includes a first shock wave electrode L1, a second shock wave electrode L2,..., and an nth shock wave electrode Ln. Among them, the first shock wave electrode L1 is correspondingly electrically connected to the first energy storage capacitor C1, the second shock wave electrode L2 is correspondingly electrically connected to the second energy storage capacitor C2, and the nth shock wave electrode Ln is correspondingly electrically connected to the nth energy storage capacitor. Taking the first shock wave electrode L1 and the first energy storage capacitor C1 as an example, one end of the first shock wave electrode L1 is connected to one end of the first energy storage capacitor C1, and both are connected to the positive pole of the boost circuit. The other end of the first shock wave electrode L1 is connected to the other end of the first energy storage capacitor C1, and both are connected to the first end of the second energy storage capacitor C2. The connection method of the subsequent shock wave electrodes is the same as the above solution, and no further elaboration is made here.

[0057] As Figure 5 shown, in an embodiment provided by the present invention, the second connection circuit of the previous discharge unit is adjacent to the first connection circuit of the adjacent discharge unit. In this embodiment, two adjacent discharge units are independent of each other, and at least one of the first connection circuit and the second connection circuit is provided with at least one electrode switch-type component, that is, there are the following three ways: First, at least one electrode switch-type component is provided on the first connection circuit, and no electrode switch-type component is provided on the second connection circuit; Second, no electrode switch-type component is provided on the first connection circuit, and at least one electrode switch-type component is provided on the second connection circuit; Third, at least one electrode switch-type component is provided on the first connection circuit, and at least one electrode switch-type component is also provided on the second connection circuit.

[0058] By cleverly configuring electrode switch-type components in the connection circuit of the discharge unit, the present invention realizes independent control between discharge units and flexible discharge combinations. This design not only enhances the system's ability to regulate the discharge process but also allows precise control of the working modes of each discharge unit through different combinations of switches, whether discharging alone or cooperating with adjacent units. Such a design improves the adaptability and operation flexibility of the system, enabling adjustment of the discharge strategy according to actual needs, optimizing the discharge efficiency and the characteristics of the output shock wave, and enhancing the controllability of the treatment effect and the overall performance of the power supply system.

[0059] As Figure 4As shown, in another embodiment, the second connection circuit of the previous discharge unit and the first connection circuit of the adjacent discharge unit are the same circuit. This configuration effectively simplifies the circuit layout, reduces the number of independent circuits required, thereby reducing the overall system complexity and manufacturing cost. At the same time, this design also increases the synergy between the discharge units, enabling the discharge process to be more coherent and synchronous, improving the working efficiency and stability of the shock wave generating device. In addition, this circuit layout helps to improve the efficiency of energy transmission, making the generation of shock waves more efficient and controllable, and further enhancing the effect and safety of shock wave therapy.

[0060] It should be noted that in the above two embodiments, at least one electrode switch type component is provided in all the first connection circuits, and at least one electrode switch type component is also provided in all the second connection circuits. The specific number selected can be chosen according to different working requirements, and other components can be provided between adjacent two electrode switch type components to meet different working needs, and no detailed examples will be given here.

[0061] In one embodiment of the present invention, each discharge unit includes at least one shock wave electrode. Specifically, the following embodiments are included:

[0062] If all the shock wave electrodes belonging to the same discharge unit are electrically connected to the second single circuit, one end of the second single circuit is electrically connected to one end of the corresponding energy storage unit through the first connection circuit, and the other end of the second single circuit is electrically connected to the other end of the corresponding energy storage unit through the second connection circuit.

[0063] As Figure 6 As shown, in this embodiment, a plurality of shock wave electrodes L1, L2, and L3 are included. The above L1 to L3 are connected end to end in sequence, and one end of L1 is connected to one end of the second single circuit, and the other end of L3 is connected to the other end of the second single circuit. Both ends of the first energy storage capacitor C1 are connected to both ends of the second single circuit, and both ends of the first voltage balancing resistor R1 are respectively connected to both ends of the first energy storage capacitor C1. The first electrode switch type component SW2 and the second electrode switch type component SW3 are respectively provided on the first connection circuit and the second connection circuit.

[0064] It should be noted that this embodiment includes: the first electrode switch type component SW2, the second electrode switch type component SW3... and the (n + 1)th electrode switch type component SWn+2. At the same time, a power switch type component SW1 is also included, and its specific installation position refers to the appendix Figures 4 to 9 As shown, no detailed description will be given here.

[0065] Of course, the present invention is not limited to the above embodiments. As Figure 4As shown, the present invention also provides an embodiment in which each energy storage unit corresponds to only one shock wave electrode. In an embodiment not shown, the above three embodiments can be combined, that is, in the same circuit, there can be a scheme in which one energy storage unit corresponds to one shock wave electrode, or a scheme in which one energy storage unit corresponds to multiple shock wave electrodes.

[0066] Preferably, the shock wave power supply of the present invention further includes a voltage-limiting type protection component, and the voltage-limiting type protection component and the shock wave electrode are electrically connected in the same single circuit; moreover, the voltage-limiting type protection component is in an open state when the voltage across its two ends does not reach the breakdown voltage, and the voltage-limiting type protection component is in a conducting state when the voltage across its two ends reaches the breakdown voltage.

[0067] Specifically, the voltage-limiting type protection component is a gas discharge tube or a varistor.

[0068] In the embodiment of the present invention, each discharge unit further includes at least one voltage balancing resistor.

[0069] Specifically referring to Figure 4 As shown, the embodiment of the present invention includes a first voltage balancing resistor R1, a second voltage balancing resistor R2... and an nth voltage balancing resistor Rn, where the first voltage balancing resistor R1 corresponds to the first energy storage capacitor C1, the second voltage balancing resistor R2 corresponds to the second energy storage capacitor C2, and the nth voltage balancing resistor Rn corresponds to the nth energy storage capacitor Cn. Here, taking the discharge unit where the first voltage balancing resistor R1 and the first energy storage capacitor C1 are located as an example: one end of the first voltage balancing resistor R1, one end of the first energy storage capacitor C1, and the first end of the first shock wave electrode L1 are all connected, and the other end of the first voltage balancing resistor R1, the other end of the first energy storage capacitor C1, and the other end of the first shock wave electrode L1 are all connected. Moreover, the connection points of both ends of the first voltage balancing resistor R1 with the first connection circuit and the second connection circuit are located between the first energy storage capacitor C1 and the corresponding electrode switch-type components (SW2 and SW3). The structures of other discharge units are the same as that of the above discharge unit, and thus will not be described in detail here.

[0070] Preferably, each energy storage unit includes at least one energy storage capacitor; when the same energy storage unit includes multiple energy storage capacitors, at least two energy storage capacitors belonging to the same energy storage unit are electrically connected in the same single circuit.

[0071] Electrically connecting multiple energy storage capacitors in the same single circuit can effectively increase the total working voltage of the energy storage unit, and at the same time ensure that the electric charges on each energy storage capacitor are consistent. This design not only increases the energy storage capacity and output voltage of the system, but also realizes the uniform distribution of the capacitor voltage through the voltage division effect, improving the energy conversion efficiency and the energy intensity of the shock wave.

[0072] Furthermore, the boost circuit includes a boost module, a power switch component SW1, and a rectifier diode D1 that are electrically connected to the same single circuit. Among them,

[0073] Among them, the boost module can use an AC power supply AC or a high-voltage power supply, and the power switch components are IGBT, GDT, SCR, or MOSFET. The electrode switch components are all IGBT, GDT, SCR, or MOSFET. In the embodiment of the present invention, IGBT is selected as the switch, and its action time is generally dozens of nanoseconds (ns).

[0074] As Figure 7 shown, the present invention also provides a charging method implemented by using the above-mentioned shock wave power supply. The shock wave power supply includes a first energy storage capacitor C1, a second energy storage capacitor C2, a first voltage balancing resistor R1, and a second voltage balancing resistor R2. The charging method includes:

[0075] Turn on the power switch component SW1 and turn off the electrode switch components SW2, SW3, and SW4;

[0076] When the first energy storage capacitor C1 finishes discharging and the second energy storage capacitor C2 has not started to discharge, in the charging state, the boost circuit forms a charging loop with the first energy storage capacitor C1 and the second voltage balancing resistor R2, as shown by the arrow in Figure 7 ;

[0077] When the first energy storage capacitor C1 has not started to discharge and the second energy storage capacitor C2 finishes discharging, in the charging state, the boost circuit forms a charging loop with the first voltage balancing resistor R1 and the second energy storage capacitor C2;

[0078] When the first energy storage capacitor C1 finishes discharging and the second energy storage capacitor C2 also finishes discharging, in the charging state, the boost circuit forms a charging loop with the first energy storage capacitor C1 and the second energy storage capacitor C2.

[0079] The above method is only one embodiment of the present invention and does not limit the present invention. When the energy storage capacitors and discharge units of the present invention are superimposed, and the corresponding embodiments are charged according to the above charging rules, then such embodiments should also be within the protection scope of this application.

[0101] It should be noted that in the embodiments of the present invention, the charging state and the discharging state are independent of each other, that is, when any energy storage capacitor is charging, other energy storage capacitors cannot be discharged. Similarly, when any energy storage capacitor is discharging, other energy storage capacitors cannot be charging.

[0102] After charging is completed, SW1 will disconnect to ensure the safety of the circuit.

[0103] Referring to Figure 7 As shown, the present invention also provides a discharging method implemented by using the above-mentioned shock wave power supply. The shock wave power supply includes a first shock wave electrode L1, a second shock wave electrode L2, a first electrode switch-type component SW2, a second electrode switch-type component SW3, and a third electrode switch-type component SW4. The discharging method includes:

[0104] When the first electrode switch-type component SW2 and the second electrode switch-type component SW3 are turned on and the third electrode switch-type component SW4 is turned off, the first shock wave electrode L1 discharges alone;

[0105] When the first electrode switch-type component SW2 is turned off and the second electrode switch-type component SW3 and the third electrode switch-type component SW4 are turned on, the second shock wave electrode L2 discharges alone;

[0106] When the first electrode switch-type component SW2, the second electrode switch-type component SW3, and the third electrode switch-type component SW4 are all turned on, the first shock wave electrode L1 and the second shock wave electrode L2 discharge in parallel;

[0107] When the first electrode switch-type component SW2 and the third electrode switch-type component SW4 are turned on and the second electrode switch-type component SW3 is turned off, the first shock wave electrode L1 and the second shock wave electrode L2 discharge in series.

[0108] The above method is only one embodiment of the present invention and does not limit the present invention. When the energy storage capacitors and the discharging units of the present invention are superimposed, and the corresponding embodiments discharge according to the above discharging rules, then such embodiments should also be within the protection scope of this application.

[0109] The following embodiments are provided for illustrative purposes (hereinafter, the first shock wave electrode is abbreviated as L1, the first electrode switch-type component SW2 is abbreviated as SW2, and so on).

[0110] Embodiment 3: Refer to Figure 8 As shown, the shock wave power supply includes L1, L2, and L3, and the corresponding electrode switch-type components include SW2, SW3, SW4, and SW5.

[0111] When SW2 and SW3 are conducting and SW4 and SW5 are off, L1 discharges alone.

[0112] When SW2 is off and SW3 and SW4 are conducting, L2 discharges alone.

[0113] When SW4 and SW5 are conducting and SW2 and SW3 are off, L3 discharges alone.

[0114] When SW2 and SW4 are conducting and SW3 and SW5 are off, L1 and L2 are connected to the same single circuit and discharge together.

[0115] When SW2, SW3, and SW4 are all conducting and SW5 is off, one end of L1 and L2 is electrically connected, and the other end of L1 and L2 is also electrically connected, and common discharge is achieved.

[0116] When SW2 and SW5 are conducting and SW3 and SW4 are off, L1, L2, and L3 are connected to the same single circuit and discharge together.

[0117] When SW2, SW3, and SW5 are all conducting and SW4 is off, L2 and L3 are connected to the same single circuit and discharge together. One end of L1 is connected to one end of L2, and the other end of L1 is connected to one end of L3, and L1 discharges together with the combination formed by L2 and L3.

[0118] When SW3 and SW5 are conducting and SW2 and SW4 are off, L2 and L3 are connected to the same single circuit and discharge together.

[0119] When SW3, SW4, and SW5 are all conducting and SW2 is off, one end of L2 and L3 is electrically connected, and the other end of L2 and L3 is also electrically connected, and common discharge is achieved.

[0120] When SW2, SW3, SW4, and SW5 are all conducting, one end of L1, one end of L2, and one end of L3 are electrically connected, and the other end of L1, the other end of L2, and the other end of L3 are electrically connected, and all the motors discharge together.

[0121] Refer to Figure 9As shown, the present invention also includes an embodiment with six shock wave electrodes. In this embodiment, every three shock wave electrodes form a module, and the two modules are independent of each other. The shock wave electrodes can be combined with each other. Of course, according to different needs, the present invention can also include more shock wave electrodes, which will not be explained one by one here.

[0122] It should be noted that when the discharge is completed, the corresponding electrode switch-type components will disconnect to ensure the safety of the circuit.

[0123] By the above method, the frequency of the generated shock wave can be controlled by controlling the time interval between the discharges of each shock wave electrode. Since all the energy storage capacitors have been charged before the shock wave electrodes discharge and break down, the frequency of the shock wave can be changed to a very high level without being limited by the charge and discharge time of the energy storage capacitors.

[0124] As described above, the above are only specific embodiments of the present invention, and the scope of the invention implementation cannot be limited by them. Therefore, the replacement of equivalent components or the equivalent changes and modifications made according to the protection scope of the present invention patent should still fall within the scope covered by this patent. In addition, the technical features in the present invention, between technical features, between technical features and technical solutions, and between technical solutions can be freely combined and used.
