[0006] The first shock wave component is used for expanding according to the applied pressure when positioned within the preset range of the impacted object, and converting the high pressure pulse emitted by the shock wave energy generator into shock wave energy under the condition of being connected with the shock wave energy generator, so as to act the shock wave energy on the impacted object.

[0007] The second shock wave component is used for expanding according to the applied pressure when positioned within the preset range of the impacted object after the shock wave energy acts on the impacted object and the first shock wave component has reached the sufficient expansion condition; wherein, when the expanded second shock wave component reaches the sufficient expansion condition, the impacted object reaches the preset breaking condition.

[0011] In a case where the shock wave energy generator is connected with the expanded first shock wave component, the shock wave energy generator is controlled to emit a preset number of pulses, and the pulses are converted into shock wave energy by the first shock wave component to act on the impacted object;

[0012] After the preset number of pulses are emitted, the first shock wave component is expanded according to a second preset pressure;

[0013] In a case where the expanded first shock wave component does not reach a sufficient expansion condition, the first shock wave component is contracted according to a reduced pressure, and after a preset time interval, the step of expanding the first shock wave component according to the first preset pressure is continued to be executed;

[0014] In a case where the expanded first shock wave component reaches the sufficient expansion condition, when a second shock wave component is positioned within a preset range of the impacted object, the second shock wave component is expanded according to a second preset pressure;

After the shock wave energy acts on the impacted object, at least part of the impacted object is broken. The expansion range corresponding to the first shock wave component is smaller, so that the broken condition of the impacted object cannot be accurately judged. Therefore, the second shock wave component is used for expanding according to the applied pressure when positioned in the preset range of the impacted object after the shock wave energy acts on the impacted object and the first shock wave component reaches the sufficient expansion condition. When the expanded second shock wave component reaches the sufficient expansion condition, the impacted object reaches the preset broken condition. The expansion range corresponding to the second shock wave component is larger, so that the broken condition of the impacted object can be more accurately judged compared with the first shock wave component, and the accuracy of the shock wave control is improved.

[0027] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0028] In one exemplary embodiment, as shown in Figure 1 a shock wave system 100 is provided, comprising: a first shock wave component 102, a second shock wave component 104 and a shock wave energy generator 106; the first shock wave component 102 and the second shock wave component 104 are expanded under the application of pressure, and the corresponding expansion range of the first shock wave component 102 is smaller than that of the second shock wave component.

[0029] The first shock wave component 102 is configured to expand according to the applied pressure when positioned within a preset range of the impacted object, and convert the high-pressure pulse emitted by the shock wave energy generator 106 into shock wave energy when connected to the shock wave energy generator 106, so as to act the shock wave energy on the impacted object.

[0030] In some embodiments, the first shock wave component 102 has a deformation characteristic, and the deformation of the first shock wave component 102 is caused after the application of pressure, thereby achieving the effect of expansion.

[0031] In some embodiments, the first shock wave component 102 comprises an expandable assembly. The morphology of the expandable assembly changes with pressure, and under the application of pressure, i.e., under the expansion pressure, the expandable assembly is in an expanded state and the volume increases. It can be understood that when the first shock wave component 102 is positioned within a preset range of the impacted object, it can be considered that the expandable assembly of the first shock wave component 102 reaches the impacted object, and the expandable assembly can be expanded according to the applied pressure.

[0032] In some embodiments, the first shock wave component 102 can be but is not limited to a balloon catheter. The expandable assembly can be but is not limited to a balloon.

[0033] In some embodiments, the expanded first shockwave component 102 can be in contact with at least a portion of the impacted object. It can be appreciated that the shockwave energy can be more precisely applied to the at least a portion of the impacted object in contact with the first shockwave component 102.

[0034] In some embodiments, the first shockwave component 102 is configured to expand according to a first preset pressure when positioned within a preset range of the impacted object, and to expand according to a second preset pressure after the shockwave energy is applied to the impacted object. The second preset pressure is greater than the first preset pressure. It can be appreciated that after the shockwave energy is applied to the impacted object, at least a portion of the impacted object is broken, and after the second preset pressure is applied and at least a portion of the impacted object is broken, the first shockwave component 102 expands more fully. At this time, if the expanded first shockwave component 102 does not reach a full expansion condition, the degree of breaking of the impacted object is not sufficient, and a second shockwave component with a larger expansion range does not need to be replaced. If the expanded first shockwave component 102 reaches the full expansion condition, the degree of breaking of the impacted object is sufficient, and a second shockwave component with a larger expansion range needs to be replaced.

[0035] In some embodiments, the first shockwave component 102 and the second shockwave component 104 each include an expandable assembly. The full expansion condition can be, but is not limited to, uniform expansion of the expandable assembly. It can be appreciated that if the degree of breaking of the impacted object is sufficient, the expandable assembly has sufficient space to expand, and at this time, the expandable assembly expands uniformly. If the degree of breaking of the impacted object is not sufficient, the expandable assembly does not have sufficient space to expand, and at this time, the expansion of the expandable assembly is limited by the impacted object, and the contacted portion of the impacted object cannot fully expand, which can cause the expandable assembly to expand non-uniformly.

[0036] In some embodiments, the second preset pressure is applied to the expandable assembly by injecting mixed saline and contrast medium, and it is determined whether the expandable assembly reaches the full expansion condition under the application of the second preset pressure. The expandable assembly that reaches the full expansion condition can be considered to have no or inconspicuous concave-convex features. The concave-convex features can be a middle segment waist drum or caused by narrow or obstructed tissue.

[0037] In some embodiments, the imaging subsystem of the shockwave system can include a contrast device. The contrast device can be used to determine whether the expandable assembly reaches the full expansion condition under the application of the second preset pressure.

[0038] In some embodiments, the second preset pressure includes two different sizes of expansion pressures. In the case that the expandable assembly morphology feature does not reach the preset judgment condition under the application of the smaller expansion pressure, the larger expansion pressure is applied to the expandable assembly, and in the case that the larger expansion pressure is applied, it is judged whether the expandable assembly reaches the sufficient expansion condition.

[0039] In some embodiments, the first shockwave component and the second shockwave component can be balloon catheters. The expandable assembly refers to a balloon. The second preset pressure can include an expansion pressure of 6 atm and an expansion pressure of 8 atm. The balloon is expanded by injecting a 1:1 mixed saline and contrast medium, and the expansion pressure is 6 atm. The position where the balloon is located is inspected, including but not limited to using a DSA angiography device, and the balloon morphology saturation is good, and there is no obvious feature of midsection waist drum or concave-convex caused by stenosis or obstructive tissue, and it is considered that the balloon reaches the sufficient expansion condition. If the feature is not obvious and is not conducive to observation, the pressure can be appropriately increased to 8 atm for observation.

[0040] In some embodiments, the expansion range includes a maximum expansion degree. The sufficient expansion condition can be but is not limited to that the expanded shockwave component reaches the maximum expansion degree.

[0041] In some embodiments, the expansion range includes a maximum expansion diameter. The sufficient expansion condition can be but is not limited to that the diameter of the expanded expandable assembly reaches the maximum expansion diameter. It can be understood that the maximum expansion diameter refers to the maximum diameter to which the expandable assembly in the shockwave component can expand.

[0042] In some embodiments, the first shockwave component 102 is used to contract according to a reduced pressure in the case that the sufficient expansion condition is not reached after expansion according to the applied second preset pressure, and is used to expand again according to the applied first preset pressure after a preset time interval, so as to convert the high-pressure pulse emitted by the shockwave energy generator 106 into shockwave energy to release a new round of shockwaves. It can be understood that in order to ensure the effect of the shockwave energy and improve the accuracy of the shockwave control, the first shockwave component 102 is not continuously used, but is used again after a preset time interval, so as to ensure the accuracy of the shockwave control.

[0043] In some embodiments, the impacted objects are distributed inside the cavity, and the size of the space inside the cavity is fixed. If the distribution area of the impacted objects is larger, it means that the remaining space inside the cavity is smaller, and at this time, the shock wave component with a smaller expansion range is more suitable for the impacted objects. After the shock wave energy acts on the impacted objects, at least part of the impacted objects is broken, the distribution area of the impacted objects becomes smaller, and the remaining space inside the cavity becomes larger, and at this time, the shock wave component with a larger expansion range is more suitable for the impacted objects. The above-mentioned impacted objects can be calcified tissue in the cavity or blood vessel, etc.

[0044] In some embodiments, the impacted objects are distributed inside the cavity of the target object. The operator can introduce the shock wave component into the cavity and position it within the predetermined range of the impacted objects.

[0045] In some embodiments, the impacted objects are distributed inside the tube or cavity of the target object. The operator can introduce the shock wave component into the tube or cavity and position it to the impacted objects.

[0046] In some embodiments, the entrance to the cavity requires passing through a narrow passage, so the shock wave component includes a component with an elongated structure.

[0047] In some embodiments, the main body of the first shock wave component 102 and the second shock wave component 104 can be an elongated tubular structure, i.e., an expandable component. It can be understood that in the initial state, the first shock wave component 102 and the second shock wave component 104 are elongated tubular structures, which can pass through the narrow passage to enter the cavity. When the first shock wave component 102 or the second shock wave component 104 is positioned to the impacted objects, the expandable component in the first shock wave component 102 or the second shock wave component 104 will deform, i.e., expand, according to the applied pressure. The positioning of the first shock wave component 102 or the second shock wave component 104 to the predetermined range of the impacted objects actually means that the expandable component with deformation characteristics of the first shock wave component 102 or the second shock wave component 104 is positioned to the impacted objects.

[0048] In some embodiments, the second shock wave component 104 corresponds to an expansion range matching a distribution area of the impacted object; the shock wave system comprises at least one preceding shock wave component; the expansion range corresponding to the preceding shock wave component is smaller than the expansion range corresponding to the second shock wave component 104; the preceding shock wave component is used as the first shock wave component 102 in ascending order of the expansion range; the second shock wave component 104 is used to expand according to the applied pressure when positioned within the preset range of the impacted object after the shock wave energy acts on the impacted object and the last preceding shock wave component reaches the sufficient expansion condition; the last preceding shock wave component refers to the preceding shock wave component with the largest expansion range among the at least one preceding shock wave component.

[0049] Wherein, the preceding shock wave component refers to the shock wave component used before the second shock wave component 104. It can be understood that before the second shock wave component 104 is positioned within the preset range of the impacted object, the at least one preceding shock wave component is respectively positioned within the preset range of the impacted object as the first shock wave component 102.

[0050] It can be understood that the expansion range corresponding to the second shock wave component 104 matches the distribution area of the impacted object, that is, after the second shock wave component 104 is fully expanded, it represents that the fragmentation degree of the impacted object within the corresponding distribution area is sufficient, and it can be considered that the fragmentation of the impacted object is completed. The larger the distribution area of the impacted object is, the more preceding shock wave components used before the second shock wave component 104. Each time the preceding shock wave component used is larger than the preceding shock wave component used last time, the expansion range corresponding to the preceding shock wave component is larger, which can gradually deliver the shock wave energy to a larger range, realize the shock wave energy acting on the impacted object in a larger range, and thus gradually and accurately fragment the impacted object in a larger range.

[0051] In some embodiments, the shock wave component can be but is not limited to being manually positioned to the impacted object by an operator. The shock wave component comprises at least one of the first shock wave component 102 or the second shock wave component 104.

[0052] The second shock wave component 104 is used to expand according to the applied pressure when positioned within the preset range of the impacted object after the shock wave energy acts on the impacted object and the first shock wave component 102 has reached the sufficient expansion condition; wherein, the impacted object reaches the preset fragmentation condition when the expanded second shock wave component 104 reaches the sufficient expansion condition.

[0053] In some embodiments, the impacted object can be located inside a cavity of the target object. The second shockwave component 104 matches the space inside the cavity. It can be understood that after the impacted object inside the cavity is broken, the space inside the cavity is released, at this time, the expandable component of the second shockwave component 104 can fully expand after being applied with pressure, and thus the second shockwave component 104 can be used to determine whether the impacted object reaches the preset breaking condition. The reaching of the preset breaking condition represents that the breaking of the impacted object is completed.

[0054] In some embodiments, in the case that the expanded second shockwave component 104 does not reach the full expansion condition after being applied with pressure, the second shockwave component 104, in the case of being connected with the shockwave energy generator 106, converts the high-pressure pulse emitted by the shockwave energy generator 106 into shockwave energy to act on the impacted object. It can be understood that both the second shockwave component 104 and the first shockwave component 102 can act on the impacted object with shockwave energy. After the second shockwave component 104 acts on the impacted object with shockwave energy, it will continue to expand according to the applied pressure. If the expanded second shockwave component 104 still does not reach the full expansion condition, in the case that the target number of pulses is not all emitted, after a preset time interval, the step of converting the high-pressure pulse emitted by the shockwave energy generator 106 into shockwave energy to act on the impacted object in the case of being connected with the shockwave energy generator 106 is continued.

[0055] In some embodiments, the first shockwave component 102 is configured to expand according to a first preset pressure when positioned within a preset range of the impacted object, and expand according to a second preset pressure after the shockwave energy acts on the impacted object; the second preset pressure is greater than the first preset pressure; the second shockwave component 104 is configured to expand according to the second preset pressure when positioned within the preset range of the impacted object in the case that the first shockwave component 102 reaches the full expansion condition after expanding according to the second preset pressure.

[0056] In some embodiments, in the case that the expanded second shockwave component 104 does not reach the full expansion condition after being applied with the second preset pressure, the second shockwave component 104 shrinks according to a reduced pressure, and expands again according to the first preset pressure after a preset time interval, and converts the high-pressure pulse emitted by the shockwave energy generator 106 into shockwave energy to act on the impacted object in the case of being connected with the shockwave energy generator 106.

[0057] In some embodiments, the first preset pressure ranges from 4 to 5 atmospheres, and the second preset pressure ranges from 6 to 8 atmospheres. Atmospheres (atm) are the unit of atmospheric pressure. 1 atm equals 101.325 kPa (kilopascal).

[0058] In some embodiments, the second shock wave component 104 may be, but is not limited to, a balloon catheter.

[0059] In some embodiments, the first shock wave component 102 and the second shock wave component 104 are both balloon catheters; wherein the balloon diameter of the first shock wave component 102 ranges from 4 mm to 8 mm; and the balloon diameter of the second shock wave component 104 ranges from 10 mm to 12 mm.

[0060] In some embodiments, when the first shock wave component 102 expands to a sufficient expansion condition under the applied second preset pressure, the operator can replace the first shock wave component 102 with a second shock wave component 104, which is positioned against the impacted object. At this time, the first shock wave component 102 is removed. It can be understood that the applied first preset pressure is used to control the first shock wave component 102 or the second shock wave component 104 to contact at least a portion of the impacted object after expansion. The applied second preset pressure is used to determine whether the first shock wave component 102 or the second shock wave component 104 has expanded sufficiently.

[0061] Shock wave energy generator 106 is used to generate high-voltage pulses when connected to the expanded first shock wave component 102.

[0062] In some embodiments, the high-voltage pulse includes a preset number of pulses; the shock wave energy generator 106 is used to release the preset number of pulses when connected to the expanded first shock wave component 102 or the expanded second shock wave component 104.

[0063] In some embodiments, such as Figure 2 As shown, another shock wave system 100 is provided. The shock wave system may include a third shock wave component 108. The third shock wave component 108 is smaller than the first shock wave component 102 and the second shock wave component 104. The third shock wave component 108, when positioned within a preset range of the impacted object and connected to a shock wave energy generator 106, converts the high-voltage pulse emitted by the shock wave energy generator 106 into shock wave energy, so as to apply the shock wave energy to the impacted object, resulting in at least partially broken impacted object; the first shock wave component 102, when positioned within a preset range of the at least partially broken impacted object, expands according to the applied pressure.

[0064] In some embodiments, the third shockwave component 108 does not have an expandable assembly, and the size of the third shockwave component 108 can be fixed.

[0065] In some embodiments, the third shockwave component 108 can be, but is not limited to, a shockwave microcatheter. The first shockwave component 102 and the second shockwave component 104 can be, but are not limited to, balloon catheters. Before using a balloon catheter, a balloon microcatheter can be used to apply shockwave energy to the impacted object, and after at least part of the impacted object is broken, a balloon catheter with a larger size can be used.

[0066] In some embodiments, an electrode is provided in the shockwave component. Through the electrode in the shockwave component, electrical energy is released and converted into acoustic mechanical energy, which is propagated to the impacted object.

[0067] In some embodiments, the shockwave energy generator 106 includes an energy host. The energy host can be used to generate high-voltage current.

[0068] In some embodiments, the shockwave energy generator 106 includes a cable. The cable can be used to transmit high-voltage current to the electrode.

[0069] In some embodiments, the shockwave energy generator can include an energy host, a handle cable, and a catheter cable. The energy host is used to generate high-voltage energy, and the handle cable and the catheter cable are used for high-voltage energy transmission. The shockwave energy generator can be used for different specifications of shockwave components for different purposes, and at least one energy parameter such as voltage, current, or output power is adjusted to achieve the purpose of accurately outputting shockwaves. For example, for a shockwave component used to eliminate heart valve calcification, the output voltage range is 4KV to 8KV. For a shockwave component used to eliminate vascular calcification, the output voltage range is 1.5KV to 4KV.

[0070] In some embodiments, different shockwave components can correspond to different energy parameters. The energy parameters can include at least one of voltage or current or output power. It can be understood that the shockwave energy generator 106 can adjust at least one energy parameter such as voltage or current or output power for each shockwave component to achieve the purpose of accurately emitting shockwaves through each shockwave component, respectively.

[0071] In some embodiments, the same shockwave component corresponds to multiple energy parameters, and different energy parameters are suitable for different impacted objects. It can be understood that the shockwave system can be applied to multiple impacted objects, and different energy parameters are required for different impacted objects.

[0072] In some embodiments, the shockwave energy generator 106 is configured to emit high pressure energy according to an energy parameter in the case that the shockwave component is in contact with the impacted object.

[0073] In some embodiments, the shockwave energy generator 106 can obtain the energy parameter. It can be understood that the operator can select the energy parameter set for different shockwave components and different impacted objects, or manually input the energy parameter.

[0074] In the shockwave system, the shockwave system comprises a first shockwave component, a second shockwave component and a shockwave energy generator; the first shockwave component and the second shockwave component are expanded under the application of pressure, and the expansion range corresponding to the first shockwave component is smaller than the expansion range corresponding to the second shockwave component. The first shockwave component is configured to expand according to the applied pressure when positioned within a preset range of the impacted object, and convert the high pressure pulse emitted by the shockwave energy generator into shockwave energy to act on the impacted object in the case that the first shockwave component is connected with the shockwave energy generator; the shockwave energy generator is configured to emit a high pressure pulse in the case that the first shockwave component is connected with the shockwave energy generator after expansion. After the shockwave energy acts on the impacted object, at least part of the impacted object is broken, the expansion range corresponding to the first shockwave component is smaller, and the first shockwave component cannot be used to accurately determine the breaking condition of the impacted object, so the second shockwave component is configured to expand according to the applied pressure when positioned within a preset range of the impacted object after the shockwave energy acts on the impacted object and the first shockwave component has reached a sufficient expansion condition; wherein the impacted object reaches a preset breaking condition in the case that the second shockwave component reaches a sufficient expansion condition after expansion; the expansion range corresponding to the second shockwave component is larger, and compared with the first shockwave component, the second shockwave component can more accurately determine the breaking condition of the impacted object, thereby improving the accuracy of shockwave control.

[0075] In some embodiments, the shockwave system further comprises an imaging subsystem. The imaging subsystem is configured to assist in positioning the shockwave component to the impacted object. It can be understood that the operator can gradually send the shockwave component to the lesion site under the guidance of the imaging subsystem. During the delivery process, the position and direction of the shockwave component need to be constantly adjusted to ensure that it accurately reaches the position of the impacted object. The shockwave component can be the first shockwave component, the second shockwave component or the third shockwave component.

[0076] In some embodiments, the shockwave system can position the shockwave component within a preset range of the impacted object after the shockwave component is guided into the cavity by the imaging subsystem.

[0077] In some embodiments, the shockwave system can position the shockwave component within the preset range of the impacted object based on the imaging subsystem after the shockwave component is introduced into the tube.

[0078] In some embodiments, the shockwave system can further include a computer subsystem and a pressure subsystem. The computer subsystem is configured to receive an input instruction, control the high-pressure energy generator to emit high-pressure energy according to the input instruction, and control the pressure subsystem to apply pressure or decompression to the first shockwave component or the second shockwave component.

[0079] In some embodiments, the instruction can be input by an operator. The instruction can include at least one of an energy parameter or a pressure parameter. It can be understood that the pressure subsystem is configured to apply pressure or decompression to the first shockwave component or the second shockwave component according to the pressure parameter.

[0080] In some embodiments, the first shockwave component expands according to the applied pressure, and the expanded first shockwave component contacts at least part of the impacted object. Then, the computer subsystem sends a first control signal to the high-pressure energy generator according to the input first instruction, the high-pressure energy generator emits high-pressure current according to the energy parameter carried by the first control signal, the cable transmits the high-pressure current to the electrode in the first shockwave component, and the electrode in the first shockwave component converts the released electrical energy into acoustic mechanical energy. The shockwave is transmitted in the expanded first shockwave component, and since the expanded first shockwave component contacts at least part of the impacted object, the shockwave can accurately act on the impacted object. This process is the release of shockwave energy.

[0081] After the acoustic mechanical energy acts on the impacted object, i.e., after the shockwave energy is completely released, the first shockwave component 102 expands according to the applied pressure, and shrinks according to the reduced pressure when the expanded first shockwave component 102 does not reach the fully expanded condition. It can be understood that the alternation of pressure increase and pressure decrease can ensure that the over-pressing condition is avoided, and the uniform contact between the first shockwave component and the region where the impacted object is located is ensured, so that the shockwave can more uniformly and effectively act on the impacted object.

[0082] The computer system sends a second control signal to the pressure subsystem according to the input second instruction after a preset time interval, the pressure subsystem applies pressure to the first shockwave component according to the pressure parameter carried by the second control signal, and then the first shockwave component expands again according to the applied pressure. The above operation is repeated until the requirements for reaming or impacting the impacted object are met.

[0083] In some embodiments, after the shock wave energy is released, the computer subsystem sends a third control signal to the pressure subsystem according to the input third instruction, and the pressure subsystem applies pressure to the first shock wave component according to the pressure parameter carried by the third control signal. The pressure parameter carried by the third control signal is not less than the pressure parameter carried by the second control signal. It can be understood that after the action of the shock wave, at least part of the impacted object is softened, loosened, differentiated or broken, etc., so that the expandable space of the first shock wave component is larger, at this time, a larger pressure is applied to the first shock wave component, so that the first shock wave component is more fully expanded, if the first shock wave component cannot be fully expanded, i.e. the fully expanded condition is not reached, then the first shock wave component is not replaced and is used for the next shock wave release, until the first shock wave component is fully expanded. If the first shock wave component is fully expanded, i.e. the fully expanded condition is reached, then the first shock wave component completes the hole expansion or impact on the impacted object, and the first shock wave component is replaced by a second shock wave component with a larger expansion range.

[0084] In some embodiments, after the computer subsystem obtains the input instruction, the instruction is parsed to obtain the corresponding control parameter, and then a notification signal carrying the control parameter is generated. The control parameter can include at least one of the energy parameter or the pressure parameter.

[0085] In some embodiments, by controlling the number and parameters of the pulses emitted by the shock wave energy generator, the release times and intensity of the shock wave can be controlled. For example, the energy parameter carried by the first control signal can include a preset number of pulses. For example, the operator selects 10 pulses for a cycle, then the shock wave energy generator can release 10 pulses each time. The shock wave energy generator is used to release the preset number of pulses carried by the first control signal when the first shock wave component or the second shock wave component is in contact with the impacted object.

[0086] In some embodiments, the pressure subsystem is a hydraulic system, and pure water, developer or physiological saline is pumped into the expandable assembly of the first shock wave component or the second shock wave component through the hydraulic system to expand it to the first preset pressure or the second preset pressure.

[0087] In some embodiments, the pressure subsystem is used to apply the first preset pressure to the first shock wave component or the second shock wave component according to the pressure parameter carried by the second control signal. It can be understood that the pressure parameter carried by the second control signal is used to represent the first preset pressure. The pressure subsystem is also used to apply the second preset pressure to the first shock wave component or the second shock wave component according to the pressure parameter carried by the third control signal. The pressure parameter carried by the third control signal is used to represent the second preset pressure.

[0088] In some embodiments, when the second shockwave component does not reach the fully expanded condition after expanding according to the applied second preset pressure, the second shockwave component expands according to the applied first preset pressure and contacts at least part of the impacted object, and then the computer subsystem sends a first control signal to the shockwave energy generator according to the input first instruction, the shockwave energy generator emits a high pressure pulse according to the energy parameter carried by the first control signal, the cable transmits the high pressure pulse to the electrode in the second shockwave component, and the electrode in the second shockwave component converts the high pressure pulse into shockwave energy. After the shockwave energy acts on the impacted object, i.e. after the shockwave energy is completely released, the second shockwave component expands according to the applied second preset pressure, and when the expanded second shockwave component reaches the fully expanded condition, the expansion or impact of the impacted object is completed.

[0089] In some embodiments, the computer subsystem sends a fourth control signal to the pressure subsystem according to the input fourth instruction. The pressure subsystem is used to depressurize the first shockwave component or the second shockwave component according to the fourth control signal, so that the expansion degree of the first shockwave component or the second shockwave component decreases and moves away from the impacted object.

[0090] In some embodiments, the first shockwave component and the second shockwave component are both balloon catheters. The shockwave system includes a first shockwave component A1 with a balloon diameter of 6mm, a first shockwave component A2 with a balloon diameter of 8mm, a first shockwave component A3 with a balloon diameter of 10mm, a first shockwave component A4 with a balloon diameter of 12mm, a first shockwave component A5 with a balloon diameter of 12mm, and a second shockwave component B1 with a balloon diameter of 18mm.

[0091] The impacted object is inside the target object. First, A1 is determined as the first shock wave component, and A1 is positioned to the impacted object. The balloon is filled with a mixture of developer and / or physiological saline. After expansion, A1 is in full contact with the impacted object. The shock wave energy generator 104 emits high pressure energy. The high pressure energy is transmitted through the handle cable and / or catheter cable. The shock wave energy is released in the electrode inside A1. The released shock wave energy is converted into acoustic mechanical energy. The energy is transmitted to the impacted object, softening / loosening / differentiating the impacted object. By further pressurizing A1, the expansion of A1 is achieved, and the expansion of the target object inside which the impacted object is located is achieved. After A1 is fully expanded, A2 with a larger balloon diameter is selected as the first shock wave component to repeat the above steps, and the target object inside is expanded again. After A2 is fully expanded, A3, A4, and A5 are selected in turn as the first shock wave component. After A5 is fully expanded, B1 is selected to repeat the above steps, and B1 is fully expanded to represent that the impacted object reaches the preset breaking condition. The shock wave energy release can be achieved through liquid-electric reaction. It can be understood that the target object inside can be a cavity or a tube. If the distribution area of the impacted object inside the target object is smaller, the remaining space inside the target object is larger, and A1 with a too small balloon diameter as the first shock wave component may not be in contact with at least part of the impacted object. Therefore, A2 or A3 or A4 or A5 with a larger balloon diameter can be directly selected as the first shock wave component, and the above steps are performed from A2 or A3 or A4 or A5 with a larger balloon diameter.

[0092] In some embodiments, the shock wave system can be used to eliminate the impacted object in the cavity. The shock wave system can be used to eliminate the calcification of the heart valve. At this time, the first shock wave component and the second shock wave component used are balloon catheters. After the balloon catheter is filled with liquid, the balloon diameter ranges from 5mm to 20mm, and the balloon length ranges from 15mm to 65mm.

[0093] In some embodiments, the balloon in the shock wave component can be filled with a mixture of physiological saline and developer to a first preset pressure or a second preset pressure.

[0094] In some embodiments, the shock wave system can also be used to eliminate the impacted object in the tube. For example, the shock wave system can be used to eliminate the calcification of the blood vessel. At this time, the first shock wave component and the second shock wave component used are balloon catheters. After the balloon catheter is filled with liquid, the balloon diameter ranges from 2mm to 5mm, and the balloon length ranges from 5mm to 15mm.

[0095] In some embodiments, the shockwave system, in the process of eliminating calcification in blood vessels: the balloon in the shockwave component enters the calcification lesion site -> the balloon is inflated by injecting a contrast solution and / or a physiological saline mixed liquid -> the inflated balloon is in full contact with the calcification lesion site -> the shockwave energy generator emits high-voltage energy -> voltage or current pulse energy transmission is performed through the handle cable and / or the catheter cable -> high-voltage voltage or current energy is released (liquid-electric reaction) by the balloon electrode -> the released electric energy is converted into acoustic mechanical energy -> the energy is transmitted to the calcification lesion site to soften / loosen / differentiate the calcification part.

[0096] In some embodiments, the shockwave system comprises a generator start button; the generator start button is used to trigger the shockwave energy generator to emit a high-voltage pulse.

[0097] In some embodiments, the computer subsystem can send a first control signal to the shockwave energy generator to control the shockwave energy generator to emit a high-voltage pulse in response to the triggering operation of the generator start button.

[0098] In some embodiments, the computer subsystem can determine that the generator start button is effective in response to the enabling operation of the generator start button, and in the case that the generator start button is effective, the computer subsystem can respond to the triggering operation of the generator start button. It can be understood that the operator can enable the generator start button, and then trigger the generator start button to quickly and conveniently input the first instruction. The generator start button is a human-computer interaction element for inputting the first instruction.

[0099] In some embodiments, the computer subsystem can obtain the triggering operation of the generator start button in the case that the generator start button is pressed.

[0100] The above-mentioned various components of the shockwave system can be realized by software, hardware, and combinations thereof, in whole or in part. The above-mentioned various components can be embedded in or independent of the processor in the computer device in hardware form, or stored in the memory in the computer device in software form, so as to be called and executed by the processor to perform the operations corresponding to the above-mentioned various components.

[0101] Based on the same inventive concept, the embodiments of the present application also provide a shockwave control method. The implementation scheme for solving the problem provided by the method is similar to the implementation scheme described in the above system, so the specific limitations in one or more shockwave control method embodiments provided below can be referred to the limitations of the shockwave system in the above, which will not be repeated here.

[0102] In one exemplary embodiment, as Figure 3As shown, a shock wave control method is provided, and the method is described by taking the application of the shock wave system as an example, including the following steps 302 to 312.

[0103] Step 302, in the case where the first shock wave component is positioned within the preset range of the impacted object, expanding the first shock wave component according to a first preset pressure.

[0104] Step 304, in the case where the shock wave energy generator is connected to the expanded first shock wave component, controlling the shock wave energy generator to emit a preset number of pulses, converting the pulses into shock wave energy through the first shock wave component, and applying the shock wave energy to the impacted object.

[0105] Step 306, after the preset number of pulses are emitted, expanding the first shock wave component according to a second preset pressure.

[0106] Step 308, in the case where the expanded first shock wave component does not reach a sufficient expansion condition, contracting the first shock wave component according to a reduced pressure, and after a preset time interval, returning to the step of expanding the first shock wave component according to the first preset pressure for continuous execution.

[0107] Step 310, in the case where the expanded first shock wave component reaches the sufficient expansion condition, when the second shock wave component is positioned within the preset range of the impacted object, expanding the second shock wave component according to a second preset pressure.

[0108] Step 312, in the case where the expanded second shock wave component reaches the sufficient expansion condition, determining that the impacted object reaches a preset fragmentation condition.

[0109] In some embodiments, before expanding the first shock wave component according to the first preset pressure in the case where the first shock wave component is positioned within the preset range of the impacted object, the method further includes a step of obtaining an at least partially fragmented impacted object. For example, Figure 4 As shown, a flowchart of the step of obtaining an at least partially fragmented impacted object is provided, including the following steps 402 to 404.

[0110] Step 402, in the case where the shock wave microcatheter is positioned within the preset range of the impacted object and the shock wave microcatheter is connected to the shock wave energy generator, controlling the shock wave energy generator to emit a high-pressure pulse.

[0111] Step 404, converting the high-pressure pulse into shock wave energy through the shock wave microcatheter, applying the shock wave energy to the impacted object, and obtaining an at least partially fragmented impacted object.

[0112] In some embodiments, the method further comprises: determining, in ascending order of the expansion range, the shock wave components in the at least one preceding shock wave component as a first shock wave component; the expansion range corresponding to the preceding shock wave component is smaller than the expansion range corresponding to a second shock wave component; in the case that the expanded first shock wave component reaches the sufficient expansion condition, when the second shock wave component is positioned within the preset range of the impacted object, expanding the second shock wave component according to the second preset pressure, comprising: in the case that the expanded first shock wave component reaches the sufficient expansion condition, if the first shock wave component is the last preceding shock wave component, when the second shock wave component is positioned within the preset range of the impacted object, expanding the second shock wave component according to the second preset pressure.

[0113] In some embodiments, after the preset time interval, the step of expanding the first shock wave component according to the first preset pressure is continued to be executed, comprising: in the case that the target number of pulses is not all emitted, after the preset time interval, the step of expanding the first shock wave component according to the first preset pressure is continued to be executed; the target number is an integer multiple of the preset number.

[0114] In some embodiments, the preset number of pulses refers to one cycle number of pulses. For example, if the target number is 10 times the preset number, in the case that 10 cycle numbers of pulses are not all emitted, after the preset time interval, the step of expanding the first shock wave component according to the first preset pressure is continued to be executed.

[0115] In some embodiments, the shock wave system can stop continuing to execute the step of expanding the first shock wave component according to the first preset pressure in the case that the expanded first shock wave component does not reach the sufficient expansion condition and the target number of pulses are all emitted. It can be understood that after a shock wave component is used for multiple times, that is, after the target number of pulses are emitted by the same shock wave component, the fragmentation degree of the impacted object is still not enough, and the shock wave component cannot reach the sufficient expansion condition, the shock wave component can be stopped for use, so as to avoid waste of energy resources.

[0116] In some embodiments, the shock wave system can stop continuing to execute the step of expanding the first shock wave component according to the first preset pressure in the case that the expanded first shock wave component does not reach the sufficient expansion condition and the target number of pulses are all emitted. It can be understood that after a shock wave component is used for multiple times, that is, after the target number of pulses are emitted by the same shock wave component, the fragmentation degree of the impacted object is still not enough, and the shock wave component cannot reach the sufficient expansion condition, the shock wave component can be stopped for use, so as to avoid waste of energy resources.
