DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0040] Please refer to Figure 1-7 A shock wave system provided in an embodiment of the present application includes at least one shock wave transmitter 20, at least one transmitter sensing device 30, at least one shock wave generator 50 and a transmitter monitoring module 150; the relative position between the transmitter sensing device 30 and the shock wave transmitter 20 is fixed; the shock wave transmitter 20 is electrically connected to the shock wave generator 50, and the transmitter monitoring module 150 is electrically connected to the transmitter sensing device 30 and the shock wave generator 50 respectively; the transmitter sensing device 30 is used to collect target state parameters of the shock wave transmitter 20 under the working state, and there is a preset corresponding relationship between the target state parameters and the discharge energy of the shock wave transmitter 20; the transmitter monitoring module 150 is used to receive the target state parameters transmitted by the transmitter sensing device 30, and when the target state parameters do not meet the preset discharge conditions, output a generator negative feedback signal to the shock wave generator 50, and the generator negative feedback signal is used to instruct the shock wave generator 50 to stop charging.

[0041] In some embodiments, the shock wave transmitter 20 is placed in the body at the calcified lesion that needs to be treated, such as the calcified lesion in the heart valve and blood vessels, and the shock wave generator 50 is placed outside the body. The shock wave transmitter 20 in the body and the shock wave generator 50 outside the body are electrically connected through a cable. The shock wave transmitter 20 in the body receives the voltage or current pulses emitted by the shock wave generator 50 outside the body to generate shock waves. The energy of the shock wave can loosen and rupture the calcified plates in the heart valve and blood vessels to achieve the treatment effect.

[0042] Furthermore, during the discharge process of the shock wave transmitter 20, the target state parameter of the shock wave transmitter 20 is used to indicate the discharge energy size of the shock wave transmitter 20 under the current working state. The transmitter sensing device 30 corresponding to the shock wave transmitter 20 collects the target state parameter generated by each discharge of the shock wave transmitter 20 and transmits it to the transmitter monitoring module 150; the transmitter monitoring module 150 receives the target state parameter and determines whether the target state parameter satisfies the preset discharge condition. If the target state parameter does not satisfy the preset discharge condition, it indicates that the current working state of the shock wave transmitter 20 is The previous discharge is invalid. When the current discharge of any shock wave transmitter 20 is invalid, the transmitter monitoring module 150 transmits a generator negative feedback signal to the shock wave generator 50, and the shock wave generator 50 stops charging in response to the generator negative feedback signal. If the target state parameter satisfies the preset discharge condition, it means that the current discharge of the shock wave transmitter 20 is valid. When the current discharge of all shock wave transmitters 20 is valid, the transmitter monitoring module 150 transmits a generator positive feedback signal to the shock wave generator 50, and the shock wave generator 50 charges in response to the generator positive feedback signal. Specifically, satisfying the preset discharge condition may be that each parameter in the target state parameter is within a preset range of each parameter.

[0043] In one embodiment, when the shock wave transmitter 20 fails to discharge, it indicates that the shock wave system is abnormal, and the shock wave transmitter 20 is controlled to stop working. Optionally, when the shock wave transmitter 20 fails to discharge, a fault warning message is generated and displayed. Specifically, the fault message is displayed by the display device of the shock wave generator 50, or the fault light of the shock wave generator 50 flashes.

[0044] The present application provides a transmitter sensing device on the shock wave transmitter and electrically connects it to the transmitter monitoring module, so as to monitor the target state parameters of the shock wave transmitter in real time under the working state, and then judge whether to output a generator negative feedback signal to the shock wave generator based on the target state parameters and the preset discharge conditions, so as to realize the real-time monitoring and feedback of the energy output of the shock wave transmitter, and then timely control the charging state of the shock wave generator, thereby significantly improving the safety and controllability of the system.

[0045] In the embodiment of the present application, the shock wave system also includes at least one balloon 40, in which a shock wave transmitter 20, a transmitter sensing device 30 and a positioning inner tube 10 are arranged; the shock wave transmitter 20 is fixedly connected to the positioning inner tube 10, and the transmitter sensing device 30 is fixedly connected to the positioning inner tube 10; in the axial direction of the positioning inner tube 10, there is a preset distance between the detection point of the transmitter sensing device 30 and the discharge point of the shock wave transmitter 20, and the preset distance is determined based on the effective sensing area of ​​the transmitter sensing device 30 and the discharge capacity of the shock wave transmitter 20. When the distance between the detection point of the transmitter sensing device 30 and the discharge point of the shock wave transmitter 20 meets the preset distance, the shock wave generated when the discharge point of the shock wave transmitter 20 discharges can be accurately collected by the transmitter sensing device 30, and the discharge energy value of the shock wave signal received by the transmitter sensing device 30 is less than the preset warning value, and the preset warning value represents the lower limit of the discharge energy that the transmitter sensing device 30 can withstand when it is damaged.

[0046] At the same time, by setting a corresponding transmitter sensing device 30 for each shock wave transmitter 20 and collecting the sensing signals of each transmitter sensing device 30 respectively, the accurate collection and feedback of the shock wave energy of each shock wave transmitter 20 is ensured, and at the same time, the shock wave transmitter 20 with abnormal working status can be accurately located.

[0047] Furthermore, the balloon 40 is filled with an electrolyte liquid, and the electrolyte liquid is used to conduct the shock wave emitted by the shock wave transmitter 20. Specifically, the electrolyte liquid includes but is not limited to heparin saline and contrast agent.

[0048] Furthermore, the fixed connection methods between the shock wave emitter 20 and the positioning inner tube 10 include but are not limited to gluing, riveting, heat shrink tube fixing and welding, and the fixed connection methods between the emitter sensing device 30 and the positioning inner tube 10 include but are not limited to gluing, riveting, heat shrink tube fixing and welding.

[0049] In some embodiments, see Figure 4 and Figure 5 The shock wave system includes a plurality of balloons 40 , and the shock wave system also includes an interventional catheter 250 . The plurality of balloons 40 are adjacently and parallelly arranged on the periphery of the interventional catheter 250 .

[0050] Specifically, driven by the interventional catheter 250, the balloon 40, the shock wave transmitter 20, the transmitter sensing device 30 and the positioning inner tube 10 can enter the calcified lesion that needs to be treated in the human body.

[0051] For further information, see Figure 2 and Figure 3In the case where the shock wave system includes a balloon 40, the interventional catheter 250 extends into the balloon 40, and the portion of the catheter of the interventional catheter 250 extending into the balloon 40 is the positioning inner tube 10. Specifically, the shock wave transmitter 20 is fixedly connected to the portion of the catheter of the interventional catheter 250 extending into the balloon 40, and the transmitter sensing device 30 is fixedly connected to the portion of the catheter of the interventional catheter 250 extending into the balloon 40. In this way, the number of parts of the shock wave system can be reduced, thereby reducing the structural complexity of the shock wave system.

[0052] In the embodiment of the present application, the preset distance is greater than or equal to 3 mm and less than or equal to 5 mm. Specifically, the setting of the preset distance needs to take into account the discharge energy of the shock wave transmitter 20, so that the target state parameters generated by the shock wave transmitter 20 can be accurately collected, and the high-energy shock wave can be prevented from damaging the transmitter sensing device 30, thereby extending the service life of the transmitter sensing device 30.

[0053] In the embodiment of the present application, the transmitter sensing device 30 includes at least one of a pressure sensor, a photoelectric sensor and a temperature sensor, and the target state parameter includes at least one of an acoustic wave pressure parameter in the balloon, a discharge spark intensity parameter and a temperature parameter.

[0054] In one embodiment, the transmitter sensing device 30 includes a pressure sensor, and accordingly, the target state parameter includes the acoustic wave pressure parameter in the balloon. When the shock wave transmitter 20 is discharged, if the acoustic wave pressure parameter generated by the current discharge of the shock wave transmitter 20 collected by the pressure sensor is greater than or equal to the preset pressure, it means that the current discharge of the shock wave transmitter 20 meets the first preset discharge condition, and the current discharge of the shock wave transmitter 20 is valid. Otherwise, it means that the current discharge of the shock wave transmitter 20 does not meet the first preset discharge condition, and the current discharge of the shock wave transmitter 20 is invalid. Specifically, the sampling frequency of the pressure sensor can be greater than or equal to 1MHz; the preset pressure can be 7-9MPa, and preferably, the preset pressure can be 8MPa.

[0055] In another embodiment, the transmitter sensing device 30 includes a photoelectric sensor, and correspondingly, the target state parameter includes a discharge spark intensity parameter. The delay of the photoelectric sensor needs to be less than or equal to the discharge time of the shock wave transmitter 20. Specifically, the discharge time of the shock wave transmitter 20 is 1 μs, and correspondingly, the delay of the photoelectric sensor needs to be less than or equal to 1 μs. In the case of the shock wave transmitter 20 discharging, if the discharge spark intensity parameter generated by the current discharge of the shock wave transmitter 20 collected by the photoelectric sensor is greater than or equal to the preset discharge spark intensity, it means that the current discharge of the shock wave transmitter 20 meets the second preset discharge condition, and the current discharge of the shock wave transmitter 20 is valid. Otherwise, it means that the current discharge of the shock wave transmitter 20 does not meet the second preset discharge condition, and the current discharge of the shock wave transmitter 20 is invalid. Specifically, the preset discharge spark intensity can be 100 cd.

[0056] In another embodiment, the transmitter sensing device 30 includes a temperature sensor, and accordingly, the target state parameter includes a temperature parameter in the balloon. When the shock wave transmitter 20 is discharged, if the temperature parameter of the electrolyte liquid in the balloon under the current discharge of the shock wave transmitter 20 collected by the temperature sensor is within the preset temperature range, it means that the current discharge of the shock wave transmitter 20 meets the third preset discharge condition, and the current discharge of the shock wave transmitter 20 is valid; if the temperature parameter is lower than the minimum value of the preset temperature range, it means that the current discharge of the shock wave transmitter 20 does not meet the third preset discharge condition, and the current discharge of the shock wave transmitter 20 is invalid; if the temperature parameter is higher than the maximum value of the preset temperature range, it means that the current discharge of the shock wave transmitter 20 does not meet the third preset discharge condition, indicating that the shock wave system stops working. Specifically, the preset temperature range can be 20-40°C.

[0057] In the present application, please refer to Figure 7The shock wave system also includes a regulating voltage monitoring module 60, a charging voltage monitoring module 70 and a first voltage comparison module 80, and the first voltage comparison module 80 is electrically connected to the regulating voltage monitoring module 60 and the charging voltage monitoring module 70 respectively; the shock wave generator 50 includes an electrically connected voltage regulating module 90, a charging module 100 and a high-voltage energy storage module 110; the regulating voltage monitoring module 60 is electrically connected to the voltage regulating module 90, and the charging voltage monitoring module 70 is electrically connected to the high-voltage energy storage module 110; the regulating voltage monitoring module 60 is used to detect the voltage setting signal output by the voltage regulating module 90, and transmit the voltage setting signal to the first voltage comparison module 80; the charging voltage monitoring module 70 is used to detect the current voltage signal of the high-voltage energy storage module 110, and transmit the current voltage signal to the first voltage comparison module 80; the first voltage comparison module 80 is used to compare and process the voltage setting signal and the current voltage signal to generate a voltage comparison feedback signal, and the voltage comparison feedback signal is used to indicate the on-off state between the charging module 100 and the high-voltage energy storage module 110.

[0058] Specifically, in response to the control signal sent by the first control module of the shock wave generator 50, the voltage regulating module 90 adjusts and outputs a voltage setting signal, which represents the upper voltage limit of the currently set charging module 100 charging the high-voltage energy storage module 110.

[0059] In one embodiment, the voltage regulating module 90 includes a first isolation amplifier circuit and a first voltage regulating circuit that are electrically connected. Specifically, the first voltage regulating circuit includes a first adjustable resistor.

[0060] Specifically, the charging module 100 charges or stops charging the high-voltage energy storage module 110 in response to the voltage comparison feedback signal.

[0061] Further, when the current voltage signal is less than the voltage setting signal, the first voltage comparison module 80 generates a first voltage comparison positive feedback signal, and the first voltage comparison positive feedback signal is used to instruct the charging module 100 to charge the high-voltage energy storage module 110; when the current voltage signal is greater than or equal to the voltage setting signal, the first voltage comparison module 80 generates a first voltage comparison negative feedback signal, and the first voltage comparison negative feedback signal is used to instruct the charging module 100 to stop charging the high-voltage energy storage module 110. In this way, the charging and discharging safety of the shock wave system can be guaranteed.

[0062] In the embodiment of the present application, the high-voltage energy storage module 110 includes a high-voltage energy storage capacitor 190, and the first voltage comparison module 80 includes a first comparator.

[0063] In the embodiments of this application, please refer to Figure 7The shock wave system further includes a second voltage comparison module 120, which is electrically connected to the voltage adjustment monitoring module 60; the second voltage comparison module 120 is used to receive the voltage setting signal transmitted by the voltage adjustment monitoring module 60, and compare the voltage setting signal with the output voltage threshold to generate an output voltage feedback signal, which is used to indicate the on / off state between the charging module 100 and the high-voltage energy storage module 110. The output voltage threshold represents the upper limit of the safe voltage for the charging module 100 to charge the high-voltage energy storage module 110 in the shock wave system.

[0064] Furthermore, the shock wave generator 50 further includes a threshold voltage adjustment module 240, which is electrically connected to the second voltage comparison module 120. Specifically, in response to the control signal sent by the first control module of the shock wave generator 50, the threshold voltage adjustment module 240 adjusts and outputs the output voltage threshold.

[0065] In one embodiment, the threshold voltage adjustment module 240 includes a second isolation amplifier circuit and a second voltage adjustment circuit that are electrically connected. Specifically, the second voltage adjustment circuit includes a second adjustable resistor.

[0066] Further, the second voltage comparison module 120 receives the voltage setting signal transmitted by the voltage adjustment monitoring module 60 and the output voltage threshold transmitted by the threshold voltage adjustment module 240. When the voltage setting signal is less than the output voltage threshold, the second voltage comparison module 120 generates a first output voltage feedback signal, and the first output voltage feedback signal is used to instruct the charging module 100 to charge the high-voltage energy storage module 110; when the voltage setting signal is greater than or equal to the output voltage threshold, the second voltage comparison module 120 generates a second output voltage feedback signal, and the second output voltage feedback signal is used to instruct the charging module 100 to stop charging the high-voltage energy storage module 110. In this way, the charging and discharging safety of the shock wave system can be further guaranteed.

[0067] Preferably, the second voltage comparison module 120 includes a second comparator.

[0068] In the embodiment of the present application, the charging voltage monitoring module 70 at least includes a first charging voltage monitoring circuit and a second charging voltage monitoring circuit which are provided as backup for each other.

[0069] Furthermore, both the first charging voltage monitoring circuit and the second charging voltage monitoring circuit can detect the current voltage signal of the high-voltage energy storage module 110, and transmit the current voltage signal to the first voltage comparison module 80. In this way, it can be ensured that when one of the first charging voltage monitoring circuit and the second charging voltage monitoring circuit fails, the other of the first charging voltage monitoring circuit and the second charging voltage monitoring circuit can still detect the current voltage signal of the high-voltage energy storage module 110, thereby increasing the circuit safety of the shock wave system.

[0070] In one embodiment, the first charging voltage monitoring circuit includes a first voltage-dividing resistor connected in series with the high-voltage energy storage module 110, so that the high-voltage signal at both ends of the high-voltage energy storage module 110 is converted into a weak-current signal. Specifically, the ratio of the high-voltage signal to the weak-current signal can be at least 10000:3, so that the high-voltage signal at both ends of the high-voltage energy storage module 110 can be prevented from damaging the first charging voltage monitoring circuit. In addition, the first charging voltage monitoring circuit also includes a signal processing circuit. Specifically, the signal processing circuit includes a transient voltage suppressor (TVS), a voltage follower, an inverter, and an amplifier. The transient voltage suppressor (TVS) is used to clamp the voltage of the circuit signal to avoid possible damage to the subsequent circuit by the spike voltage; the voltage follower and the inverter are used to stabilize the circuit signal; the amplifier is used to amplify the circuit signal, and the amplified circuit signal is the current voltage signal detected by the first charging voltage monitoring circuit. The second charging voltage monitoring circuit and the first charging voltage monitoring circuit are backed up for each other.

[0071] In the embodiment of the present application, the shock wave system further includes a trigger signal monitoring module 160 , which is used to generate a trigger feedback signal based on whether a generator trigger signal is received, and the trigger feedback signal is used to indicate the working state of the high-voltage energy storage module 110 .

[0072] Further, in response to the closing of the foot switch or the handle switch, the second control module of the shock wave generator 50 generates a generator trigger signal.

[0073] Further, the high-voltage energy storage module 110 includes a high-voltage energy storage capacitor 190 and a high-voltage trigger switch 200 that are electrically connected. When the high-voltage trigger switch 200 is closed, the high-voltage energy storage capacitor 190 discharges to the shock wave transmitter 20. When the high-voltage trigger switch 200 is disconnected, the high-voltage energy storage capacitor 190 cannot discharge to the shock wave transmitter 20. When the trigger signal monitoring module 160 receives the generator trigger signal, the trigger signal monitoring module 160 generates a first trigger feedback signal, the first trigger feedback signal controls the high-voltage trigger switch 200 to close, and the high-voltage energy storage capacitor 190 discharges to the shock wave transmitter 20; when the trigger signal monitoring module 160 does not receive the generator trigger signal, the trigger signal monitoring module 160 generates a second trigger feedback signal, the second trigger feedback signal controls the high-voltage trigger switch 200 to disconnect, and the high-voltage energy storage capacitor 190 cannot discharge to the shock wave transmitter 20.

[0074] In an embodiment of the present application, the shock wave system also includes a generator temperature monitoring module 130 and a generator sensing device 140 arranged on the shock wave generator 50, and the generator sensing device 140 is electrically connected to the generator temperature monitoring module 130; the generator sensing device 140 is used to collect the operating temperature of the target components in the shock wave generator 50, and transmit the operating temperature to the generator temperature monitoring module 130; the generator temperature monitoring module 130 is used to generate a generator temperature feedback signal based on the operating temperature and a preset operating temperature threshold, and the generator temperature feedback signal is used to indicate the on / off state between the charging module 100 and the high-voltage energy storage module 110.

[0075] Specifically, the target components include heat-prone components in the shock wave generator 50, and accordingly, the generator temperature monitoring module 130 includes a plurality of generator temperature monitoring circuits. The generator temperature monitoring module 130 is configured to monitor the operating temperature of the heat-prone target components in real time, so that the circuit risk caused by overheating of the heat-prone target components can be avoided, thereby increasing the circuit safety of the shock wave system.

[0076] Furthermore, when the operating temperature of the target component is less than or equal to the preset operating temperature threshold, the generator temperature monitoring module 130 generates a generator temperature positive feedback signal, and the generator temperature positive feedback signal is used to instruct the charging module 100 to charge the high-voltage energy storage module 110; when the operating temperature of the target component is greater than the preset operating temperature threshold, the generator temperature monitoring module 130 generates a generator temperature negative feedback signal, and the generator temperature negative feedback signal is used to instruct the charging module 100 to stop charging the high-voltage energy storage module 110.

Otherwise, the charging module 100 stops charging the high-voltage energy storage module 110. In this way, not only the circuit safety of the shock wave system is increased, but also the treatment effect of the shock wave system can be improved.

[0084] The following introduces specific embodiments of the present application based on the above technical solution.

[0085] Example 1

[0086] Please refer to Figure 1-3 and Figure 6-7Embodiment 1 provides a shock wave system, comprising at least one shock wave transmitter 20, at least one transmitter sensing device 30, at least one shock wave generator 50 and a transmitter monitoring module 150; the relative position between the transmitter sensing device 30 and the shock wave transmitter 20 is fixed; the shock wave transmitter 20 is electrically connected to the shock wave generator 50, and the transmitter monitoring module 150 is electrically connected to the transmitter sensing device 30 and the shock wave generator 50 respectively; the transmitter sensing device 30 is used to collect target state parameters of the shock wave transmitter 20 under the working state, and there is a preset corresponding relationship between the target state parameters and the discharge energy of the shock wave transmitter 20; the transmitter monitoring module 150 is used to receive the target state parameters transmitted by the transmitter sensing device 30, and when the target state parameters do not meet the preset discharge conditions, output a generator negative feedback signal to the shock wave generator 50, and the generator negative feedback signal is used to instruct the shock wave generator 50 to stop charging.

[0087] Furthermore, the shock wave system includes a balloon 40 and a positioning inner tube 10, a shock wave transmitter 20 and a transmitter sensing device 30 are arranged in the balloon 40, the positioning inner tube 10 extends into the balloon 40, the shock wave transmitter 20 is fixedly connected to the part of the catheter where the positioning inner tube 10 extends into the balloon 40, and the transmitter sensing device 30 is fixedly connected to the part of the catheter where the positioning inner tube 10 extends into the balloon 40.

[0088] The shock wave transmitter 20 is fixedly connected to the part of the catheter where the positioning inner tube 10 extends into the balloon 40 by gluing, and the transmitter sensing device 30 is fixedly connected to the part of the catheter where the positioning inner tube 10 extends into the balloon 40 by gluing.

[0089] In the axial direction of the positioning inner tube 10, the distance between the detection point of the transmitter sensing device 30 and the discharge point of the shock wave transmitter 20 is 4 mm. In this way, the target state parameters generated by the shock wave transmitter 20 can be accurately collected, and the damage to the transmitter sensing device 30 by the high-energy shock wave can be prevented, thereby extending the service life of the transmitter sensing device 30.

[0090] Furthermore, the shock wave system also includes a first voltage comparison module 80, a second voltage comparison module 120, a first generator temperature monitoring module, a second generator temperature monitoring module and a start signal monitoring module 170, and the shock wave system also includes a regulating voltage monitoring module 60, a charging voltage monitoring module 70, a voltage regulating module 90, a charging module 100, a high-voltage energy storage module 110, a first generator sensing device, a second generator sensing device and a threshold voltage adjustment module 240.

[0091] Further, the transmitter sensing device 30 is a pressure sensor, and accordingly, the target state parameter includes the acoustic wave pressure parameter in the balloon. When the shock wave transmitter 20 is discharged, if the acoustic wave pressure parameter generated by the current discharge of the corresponding shock wave transmitter 20 collected by the pressure sensor is greater than or equal to the preset pressure, it means that the current discharge of the shock wave transmitter 20 meets the first preset discharge condition, and the current discharge of the shock wave transmitter 20 is valid. When the current discharge of all shock wave transmitters 20 is valid, the transmitter monitoring module 150 transmits the generator positive feedback signal to the shock wave generator 50, and the shock wave generator 50 charges in response to the generator positive feedback signal; otherwise, it means that the current discharge of the shock wave transmitter 20 does not meet the first preset discharge condition, and the current discharge of the shock wave transmitter 20 is invalid. When the current discharge of any shock wave transmitter 20 is invalid, the transmitter monitoring module 150 transmits the generator negative feedback signal to the shock wave generator 50, and the shock wave generator 50 stops charging in response to the generator negative feedback signal. Specifically, the sampling frequency of the pressure sensor may be greater than or equal to 1 MHz, and the preset pressure may be 8 MPa.

[0092] At the same time, the first voltage comparison module 80 is electrically connected to the regulating voltage monitoring module 60 and the charging voltage monitoring module 70 respectively, the voltage regulating module 90, the charging module 100 and the high-voltage energy storage module 110 are electrically connected, the regulating voltage monitoring module 60 is electrically connected to the voltage regulating module 90, and the charging voltage monitoring module 70 is electrically connected to the high-voltage energy storage module 110.

[0093] Further, in response to the control signal sent by the first control module of the shock wave generator 50, the voltage regulating module 90 adjusts and outputs a voltage setting signal, and the voltage setting signal represents the upper limit of the voltage of the charging module 100 charging the high-voltage energy storage module 110. The voltage regulating monitoring module 60 is used to detect the voltage setting signal output by the voltage regulating module 90, and transmit the voltage setting signal to the first voltage comparison module 80; the charging voltage monitoring module 70 is used to detect the current voltage signal of the high-voltage energy storage module 110, and transmit the current voltage signal to the first voltage comparison module 80; the first voltage comparison module 80 is used to compare and process the voltage setting signal and the current voltage signal. When the current voltage signal is less than the voltage setting signal, the first voltage comparison module 80 generates a first voltage comparison positive feedback signal, and the first voltage comparison positive feedback signal is used to instruct the charging module 100 to charge the high-voltage energy storage module 110; when the current voltage signal is greater than or equal to the voltage setting signal, the first voltage comparison module 80 generates a first voltage comparison negative feedback signal, and the first voltage comparison negative feedback signal is used to instruct the charging module 100 to stop charging the high-voltage energy storage module 110.

[0094] Furthermore, the charging voltage monitoring module 70 includes a first charging voltage monitoring circuit and a second charging voltage monitoring circuit which are backed up to each other. Both the first charging voltage monitoring circuit and the second charging voltage monitoring circuit can detect the current voltage signal of the high-voltage energy storage module 110 and transmit the current voltage signal to the first voltage comparison module 80. In this way, it can be ensured that when one of the first charging voltage monitoring circuit and the second charging voltage monitoring circuit fails, the other of the first charging voltage monitoring circuit and the second charging voltage monitoring circuit can still detect the current voltage signal of the high-voltage energy storage module 110.

[0095] At the same time, the threshold voltage adjustment module 240 is electrically connected to the second voltage comparison module 120. In response to the control signal sent by the first control module of the shock wave generator 50, the threshold voltage adjustment module 240 adjusts and outputs the output voltage threshold; the second voltage comparison module 120 is electrically connected to the adjustment voltage monitoring module 60; the second voltage comparison module 120 is used to receive the voltage setting signal transmitted by the adjustment voltage monitoring module 60 and the output voltage threshold transmitted by the threshold voltage adjustment module 240, and compare the voltage setting signal with the output voltage threshold. When the voltage setting signal is less than the output voltage threshold, the second voltage comparison module 120 generates a first output voltage feedback signal, and the first output voltage feedback signal is used to instruct the charging module 100 to charge the high-voltage energy storage module 110; when the voltage setting signal is greater than or equal to the output voltage threshold, the second voltage comparison module 120 generates a second output voltage feedback signal, and the second output voltage feedback signal is used to instruct the charging module 100 to stop charging the high-voltage energy storage module 110.

[0096] At the same time, the high-voltage energy storage module 110 includes an electrically connected high-voltage energy storage capacitor 190 and a high-voltage trigger switch 200, the first generator sensing device is arranged on the high-voltage energy storage capacitor 190 in the shock wave generator 50, and the first generator temperature monitoring circuit is electrically connected to the first generator sensing device; the first generator sensing device is used to collect the first operating temperature of the high-voltage energy storage capacitor 190 and transmit the first operating temperature to the first generator temperature monitoring circuit; when the first operating temperature is less than or equal to the first preset operating temperature threshold, the first generator temperature monitoring circuit generates a first generator temperature positive feedback signal, and the first generator temperature positive feedback signal is used to instruct the charging module 100 to charge the high-voltage energy storage capacitor 190, and when the first operating temperature is greater than the first preset operating temperature threshold, the first generator temperature monitoring circuit generates a first generator temperature negative feedback signal, and the first generator temperature negative feedback signal is used to instruct the charging module 100 to stop charging the high-voltage energy storage capacitor 190.

[0097] At the same time, the second generator sensing device is arranged on the transformer in the charging module 100, and the second generator temperature monitoring circuit is electrically connected to the second generator sensing device; the second generator sensing device is used to collect the second operating temperature of the transformer and transmit the second operating temperature to the second generator temperature monitoring circuit; when the second operating temperature is less than or equal to the second preset operating temperature threshold, the second generator temperature monitoring circuit generates a second generator temperature positive feedback signal, and the second generator temperature positive feedback signal is used to instruct the charging module 100 to charge the high-voltage energy storage module 110, and when the second operating temperature is greater than the second preset operating temperature threshold, the second generator temperature monitoring circuit generates a second generator temperature negative feedback signal, and the second generator temperature negative feedback signal is used to instruct the charging module 100 to stop charging the high-voltage energy storage module 110.

[0098] At the same time, in response to the start switch of the shock wave system, the third control module of the shock wave generator 50 generates a generator start signal; the start signal monitoring module 170 is used to receive the generator start signal, and generate a start feedback signal when the generator start signal is received, and the start feedback signal is used to indicate the working status of the shock wave generator 50.

[0099] In the shock wave system of Example 1, the charging module 100 charges the high-voltage energy storage module 110 only when the transmitter monitoring module 150 generates a generator positive feedback signal, the first voltage comparison module 80 generates a first voltage comparison positive feedback signal, the second voltage comparison module 120 generates a first output voltage feedback signal, the generator temperature monitoring module 130 generates a generator temperature positive feedback signal, and the start signal monitoring module 170 generates a generator start signal. Otherwise, the charging module 100 stops charging the high-voltage energy storage module 110. In this way, not only the circuit safety of the shock wave system is increased, but also the therapeutic effect of the shock wave system can be improved.

[0100] Example 2

[0101] The difference between Example 2 and Example 1 lies in the number of shock wave transmitters 20 and transmitter sensing devices 30, and the shock wave system in Example 2 includes a trigger signal monitoring module 160. The similarities between Example 2 and Example 1 are not repeated here, and only the differences between Example 2 and Example 1 are described.

[0102] See also Figure 4 and Figure 5The shock wave system in Example 2 includes three balloons 40 and an interventional catheter 250. A shock wave transmitter 20, a transmitter sensing device 30 and a positioning inner tube 10 are arranged in a single balloon 40; the shock wave transmitter 20 is fixedly connected to the positioning inner tube 10, and the transmitter sensing device 30 is fixedly connected to the positioning inner tube 10; the three balloons 40 are adjacently and parallelly arranged on the periphery of the interventional catheter 250.

[0103] The shock wave transmitter 20 and the positioning inner tube 10 are fixedly connected by adhesive bonding, and the transmitter sensing device 30 and the positioning inner tube 10 are fixedly connected by adhesive bonding.

[0104] In the axial direction of the positioning inner tube 10, the distance between the detection point of the transmitter sensing device 30 and the discharge point of the shock wave transmitter 20 is 4 mm. In this way, the target state parameters generated by the shock wave transmitter 20 can be accurately collected, and the damage to the transmitter sensing device 30 by the high-energy shock wave can be prevented, thereby extending the service life of the transmitter sensing device 30.

[0105] Meanwhile, the transmitter sensing device 30 is a photoelectric sensor, and accordingly, the target state parameter includes a discharge spark intensity parameter. The delay of the photoelectric sensor needs to be less than or equal to the discharge time of the shock wave transmitter 20. Specifically, the discharge time of the shock wave transmitter 20 is 1 μs, and accordingly, the delay of the photoelectric sensor needs to be less than or equal to 1 μs. When the shock wave transmitter 20 is discharged, if the discharge spark intensity parameter generated by the current discharge of the corresponding shock wave transmitter 20 collected by the photoelectric sensor is greater than or equal to the preset discharge spark intensity, it means that the current discharge of the shock wave transmitter 20 meets the second preset discharge condition, and the current discharge of the shock wave transmitter 20 is valid. When the current discharge of all shock wave transmitters 20 is valid, the transmitter monitoring module 150 transmits the generator positive feedback signal to the shock wave generator 50, and the shock wave generator 50 charges in response to the generator positive feedback signal; otherwise, it means that the current discharge of the shock wave transmitter 20 does not meet the second preset discharge condition, and the current discharge of the shock wave transmitter 20 is invalid. When the current discharge of any shock wave transmitter 20 is invalid, the transmitter monitoring module 150 transmits the generator negative feedback signal to the shock wave generator 50, and the shock wave generator 50 stops charging in response to the generator negative feedback signal. Specifically, the preset discharge spark intensity can be 100cd.

[0106] At the same time, when the high-voltage trigger switch 200 is closed, the high-voltage energy storage capacitor 190 discharges to the shock wave transmitter 20, and when the high-voltage trigger switch 200 is disconnected, the high-voltage energy storage capacitor 190 cannot discharge to the shock wave transmitter 20. When the trigger signal monitoring module 160 receives the generator trigger signal, the trigger signal monitoring module 160 generates a first trigger feedback signal, the first trigger feedback signal controls the high-voltage trigger switch 200 to close, and the high-voltage energy storage capacitor 190 discharges to the shock wave transmitter 20; when the trigger signal monitoring module 160 does not receive the generator trigger signal, the trigger signal monitoring module 160 generates a second trigger feedback signal, the second trigger feedback signal controls the high-voltage trigger switch 200 to disconnect, and the high-voltage energy storage capacitor 190 cannot discharge to the shock wave transmitter 20. In this way, the safety of the shock wave system can be further improved.

[0107] In the shock wave system of Example 2, the charging module 100 charges the high-voltage energy storage module 110 only when the transmitter monitoring module 150 generates a generator positive feedback signal, the first voltage comparison module 80 generates a first voltage comparison positive feedback signal, the second voltage comparison module 120 generates a first output voltage feedback signal, the generator temperature monitoring module 130 generates a generator temperature positive feedback signal, and the start signal monitoring module 170 generates a generator start signal. Otherwise, the charging module 100 stops charging the high-voltage energy storage module 110. In this way, not only the circuit safety of the shock wave system is increased, but also the therapeutic effect of the shock wave system can be improved.
