[0016] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope. After reading the present invention, modifications of various equivalent forms of the present invention by those skilled in the art all fall within the scope defined in this application.

[0017] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0018] The following will be combined Figures 1 to 6The shock wave balloon catheter device and medical device of the embodiment of this specification are explained and described. It should be noted that in the embodiment of the utility model, the same reference numerals represent the same components. For the sake of brevity, the detailed description of the same components is omitted in different embodiments, and the descriptions of the same components can be referenced and quoted to each other.

[0019] As heart disease patients age and the disease progresses, plaques in peripheral blood vessels and coronary arteries gradually calcify. This bone-like structure can cause narrowing of the vessels, reduce blood flow in the vessels, and may eventually lead to complete occlusion of the vessels.

[0020] The indications of the shock wave balloon catheter device include interventional treatment of vascular calcification lesions. The shock wave balloon catheter device includes a catheter, a balloon sealed around the outer circumference of the catheter, and at least one electrode pair arranged in the balloon; the balloon can be filled with fluid; each of the electrode pairs includes a first electrode and a second electrode; when a voltage is applied between the first electrode and the second electrode, a plasma arc is formed in the fluid in the balloon between the first electrode and the second electrode, thereby generating bubbles in the fluid, which expand and collapse, and then forming a mechanical shock wave in the balloon, which is mechanically transmitted through the fluid and the balloon to apply mechanical force or pressure to split any calcified plaque on or in the wall of the vascular system.

[0021] During treatment, the balloon on the catheter is pushed into the calcified area of ​​the blood vessel; the doctor then operates the charging device to expand and pressurize the balloon; the doctor operates the pulse power supply to apply high-voltage pulses to the electrode pairs in the balloon, causing the electrode pairs to discharge and generate shock waves in the fluid; the shock waves hit the balloon wall, causing the calcified plaque to rupture; after the calcified plaque ruptures, the doctor operates the charging device to expand and pressurize the balloon a second time to open the blood vessel.

[0022] In one optional solution, the pulse power supply and electric balloon inflation pump used in conjunction with the shock wave balloon catheter are two completely independent devices; when performing treatment with the shock wave balloon catheter, it is necessary to purchase and store the pulse power supply and electric balloon inflation pump that can be used in conjunction with the catheter separately; during treatment, it is necessary to prepare the pulse power supply and electric balloon inflation pump in the operating room; in addition, it is also necessary to consider the compatibility of the shock wave balloon catheter with the pulse power supply and the electric balloon inflation pump; this brings inconvenience to many links in the application process of the shock wave balloon catheter.

[0023] A medical device provided by an embodiment of the present application is Figure 1 , Figure 2 and Figure 3As shown, it includes a host 1 and a control end; the host 1 includes an integrated pulse power supply 101 and an electric balloon inflation pump 102; the electric balloon inflation pump 102 is used to inflate the balloon 2; the pulse power supply 101 is used to deliver a pulse voltage to the electrode pair in the balloon 2; the control end is used to control the start and stop of the pulse power supply 101, and the start and stop of the electric balloon inflation pump 102.

[0024] The pulse power supply 101 and the electric balloon inflation pump 102 are integrated to form a host 1. One host 1 can simultaneously provide the pulse voltage required for the shock wave balloon catheter and the inflation and relief of the balloon 2, making the purchase, transportation, carrying and operation of the equipment easier, and the equipment at the shock wave treatment operation site is more integrated and simpler.

[0025] Optionally, the host 1 includes a shell; the pulse power supply 101 is fixed inside the shell or on the outer wall of the shell; the electric balloon inflation pump 102 is fixed inside the shell or on the outer wall of the shell.

[0026] In an optional solution, the pulse power supply and electric balloon inflation pump used in conjunction with the shock wave balloon catheter are two completely independent devices, and the switch control buttons of the two are respectively set on their respective devices; for example, the pulse power supply has a control handle, and the one control handle is provided with a pulse power switch key; the electric balloon inflation pump has another control handle, and the other control handle is provided with a switch key of the electric balloon inflation pump. This makes the doctor's operation more cumbersome, requiring multiple switching between the two handles, and also increases the risk of operational errors.

[0027] The medical device in the embodiment of the present application provides an optional solution, such as Figure 1 and Figure 2 As shown, the control end includes an operating platform, and a pulse power control key and an electric balloon inflation pump control key integrated on the operating platform; the pulse power control key is operated by the user to control the start and stop of the pulse power; the electric balloon inflation pump control key is operated by the user to control the start and stop of the electric balloon inflation pump.

[0028] Optionally, the operating platform may be a handle 103, and the pulse power control key 1031 and the electric balloon inflation pump control key 1032 are mechanical keys integrated on the handle 103; or the operating platform may be a display screen 104, and the pulse power control key 1031 and the electric balloon inflation pump control key 1032 are virtual keys integrated on the display screen 104. The pulse power control key 1031 and the electric balloon inflation pump control key 1032 may be in the form of a key, a knob, a sliding push button, etc.

[0029] The controller is configured to perform Figure 4 The following steps are shown:

[0030] S1. In response to a start instruction issued by the user through the electric balloon inflation pump control key 1032, the controller starts the electric balloon inflation pump 102 to inflate the balloon in the folded state; when the pressure of the balloon 2 reaches a first pressure threshold, the electric balloon inflation pump 102 is turned off; the first pressure threshold can be set as needed, such as 4atm (atmospheric pressure);

[0031] S2, in response to the start instruction issued by the user through the pulse power control key 1031, the controller starts the pulse power supply 101 and sends a pulse voltage; when the pulse power supply 101 sends a preset number of pulse voltages, or the duration of the pulse power supply 101 sending the pulse voltage reaches a first preset duration, the pulse power supply is turned off; for example, after the pulse power supply 101 sends 10 pulse voltages, the pulse power supply 101 is turned off;

[0032] S3, start the electric balloon inflation pump 102 to inflate the balloon 2; when the pressure of the balloon 2 reaches a second pressure threshold, turn off the electric balloon inflation pump 102; wherein the second pressure threshold is greater than the first pressure threshold; the first pressure threshold can be set as needed, for example, 6atm;

[0033] S4. When the time after the balloon pressure reaches the second pressure threshold is longer than the second preset time, start the electric balloon inflation pump 102 to relieve the pressure of the balloon to a folded state, and then turn off the electric balloon inflation pump; alternatively, the medical device also includes a pressure relief valve connected to the inner cavity of the balloon 2; when the time after the balloon 2 pressure reaches the second pressure threshold is longer than the second preset time, open the pressure relief valve to relieve the pressure of the balloon 2 to a folded state; the second preset time can be set as needed, for example, 10 seconds.

[0034] In the optional scheme of this embodiment, some operations with higher risks are performed by doctors; for example, in step S1, the doctor starts the electric balloon inflation pump 102 through the electric balloon inflation pump control key 1032, and in step S2, the doctor starts the pulse power supply 101 through the pulse power supply control key 1031, while steps S3, S4, and starting the electric balloon inflation pump 102 in step S1 and starting the pulse power supply 101 in step S2 are automatically executed by the controller.

[0035] The optional solution provided in the present application performs the inflation and depressurization of the balloon 2 and the start and stop of the pulse power supply 101 according to preset steps by integrating the pulse power supply control key 1031 and the electric balloon inflation pump control key 1032 installed on the operating platform, thereby completing the shock wave therapy, which is easy to operate and highly safe.

[0036] Optionally, the medical device further includes a pressure sensor; the pressure sensor is used to detect the pressure of the balloon 2 and transmit the pressure signal to the controller.

[0037] In step S1 of the optional scheme of this embodiment, optionally, after the doctor (operator) confirms that the balloon 2 has been delivered to the lesion location and meets the treatment conditions, the doctor issues a start command by operating the controller to start the electric balloon inflation pump 102 to inflate the balloon 2 in the folded state.

[0038] In step S1, another optional method is to identify the position of the balloon 2 by a machine, and after the balloon 2 is delivered to the lesion location and is pressurized for the first time, the machine sends a startable signal to the controller, and after the controller receives the startable signal, the controller issues a start command to start the electric balloon inflation pump 102 to inflate the folded balloon 2; wherein the machine identifies the position of the balloon 2 by an image processing algorithm, or the machine is a vascular interventional surgery robot, which can deliver the balloon 2 and identify the position of the balloon 2.

[0039] In step S2 of the optional solution of this embodiment, the method of starting the pulse power supply 101 includes one of the following:

[0040] Method 1: In response to the start-up instruction of the pulse power supply 101 issued by the operator, the controller starts the pulse power supply 101; Method 2: Considering that starting the pulse power supply 101 is relatively risky, a doctor is required to make a comprehensive judgment on whether it can be started, so the operation is performed by the doctor.

[0041] Method 2: In response to the pressure of the balloon 2 in the folded state reaching a first pressure threshold and the electric balloon inflation pump 102 being in the off state, the controller sends a signal that the pulse power supply 101 can be started; in response to the start instruction of the pulse power supply 101 issued by the operator, the controller starts the pulse power supply 101; Method 2: First, the controller determines whether the start condition of the pulse power supply 101 is met, and then sends a signal that the pulse power supply 101 can be started. The signal can be in the form of sound and light prompts, or text prompts on a display; after receiving the above signal, the doctor further determines whether to start the pulse power supply 101; this helps doctors make more accurate judgments faster and simplifies the doctor's operation.

[0042] In another optional solution of the medical device in the embodiment of the present application, Figure 3 As shown, the control end includes an operating platform and a main control key arranged on the operating platform; in response to a start instruction issued by the user through the main control key, the pulse power supply and the electric balloon inflation pump are in an enabled state.

[0043] Optionally, the operating platform may be a handle 103, and the main control key 1033 is a mechanical key integrated on the handle 103; or the operating platform may be a display screen 104, and the main control key 1033 is a virtual key integrated on the display screen 104. The main control key 1033 may be in the form of a button, a knob, a sliding button, etc.

[0044] In another optional scheme of this embodiment, optionally, in response to the start instruction issued by the user through the main control key 1033, the pulse power supply 101 and the electric balloon inflation pump 102 are in an enabled state, and the controller automatically operates to complete the shock wave treatment; for example, when the balloon is in a folded state, in response to the start instruction issued by the user through the main control key 1033, the controller automatically executes the following in sequence: Figure 5 The following steps are shown:

[0045] S1, start the electric balloon inflation pump 102 to inflate the balloon 2 in the folded state; when the pressure of the balloon 2 reaches a first pressure threshold, turn off the electric balloon inflation pump 102;

[0046] S2, starting the pulse power supply 101 to send a pulse voltage; when the pulse power supply 101 sends a preset number of pulse voltages, or the duration of the pulse power supply 101 sending the pulse voltage reaches a first preset duration, turning off the pulse power supply 101;

[0047] S3, starting the electric balloon inflation pump 102 to inflate the balloon 2; when the pressure of the balloon 2 reaches a second pressure threshold, shutting down the electric balloon inflation pump 102; wherein the second pressure threshold is greater than the first pressure threshold;

[0048] S4. When the time after the balloon pressure reaches the second pressure threshold is greater than the second preset time, the electric balloon inflation pump 102 is started to release the pressure of the balloon 2 to a folded state, and then the electric balloon inflation pump 102 is closed; or, the medical device also includes a pressure relief valve connected to the inner cavity of the balloon 2; when the time after the balloon 2 pressure reaches the second pressure threshold is greater than the second preset time, the pressure relief valve is opened to release the pressure of the balloon 2 to a folded state.

[0049] In another optional scheme of this embodiment, in response to a start instruction issued by the user through the main control key 1033, the pulse power supply 101 and the electric balloon inflation pump 102 are in an enabled state, part of the shock wave treatment operation is automatically performed by the controller, and the other part of the operation with higher risk is performed after the doctor issues an instruction; for example, the controller is configured to perform the following steps: Figure 6 The following steps are shown:

[0050] S1, the balloon 2 is in a folded state, and in response to the start instruction issued by the user through the main control key 1033 for the first time, the controller starts the electric balloon inflation pump 102 to inflate the balloon 2 in the folded state; when the pressure of the balloon 2 reaches a first pressure threshold, the electric balloon inflation pump 102 is turned off;

[0051] S2, in response to the start instruction issued by the user for the second time through the main control key 1033, the controller starts the pulse power supply 101 and sends the pulse voltage; when the pulse power supply 101 sends a preset number of pulse voltages, or the duration of the pulse power supply 101 sending the pulse voltage reaches a first preset duration, the pulse power supply 101 is turned off; in this scheme, after the step S1 is completed, the step S2 needs to start the pulse power supply 101, which is relatively risky and requires a doctor to comprehensively judge whether it can be started. Therefore, the doctor performs this operation, and the operator sends a start instruction for the second time through the main control key 1033, and the controller executes the step S2;

[0052] S3, starting the electric balloon inflation pump 102 to inflate the balloon; when the pressure of the balloon 2 reaches a second pressure threshold, shutting down the electric balloon inflation pump 102; wherein the second pressure threshold is greater than the first pressure threshold;

[0053] S4. When the time after the balloon pressure reaches the second pressure threshold is greater than the second preset time, the electric balloon inflation pump 102 is started to release the pressure of the balloon 2 to a folded state, and then the electric balloon inflation pump 102 is closed; or, the medical device also includes a pressure relief valve connected to the inner cavity of the balloon 2; when the time after the balloon 2 pressure reaches the second pressure threshold is greater than the second preset time, the pressure relief valve is opened to release the pressure of the balloon 2 to a folded state.

[0054] Another optional solution of this embodiment is to integrate the pulse power supply control key and the electric balloon inflation pump control key into a main control key 1033, through which the operator can control the pulse power supply 101 and the electric balloon inflation pump 102; specifically, by issuing a start command through the main control key 1033, steps S1, S2, S3, and S4 can be completed; this greatly reduces the difficulty of operation and reduces the risk of human operation errors. Optionally, the main control key 1033 is a mechanical key set on a handle 103; or the main control key 1033 is a virtual key set on a display screen 104. The main control key 1033 can be in the form of a button, a knob, a sliding push button, etc.

[0055] Optionally, the controller of the above embodiment has an automatic mode and a manual mode;

[0056] When placed in manual mode, at least some of the operations with higher risks in the above steps S1, S2, S3, and S4 are performed after the doctor issues an instruction; for example, starting the electric balloon inflation pump 102 in step S1 and starting the pulse power supply 101 in step S2 are performed after the doctor issues an instruction, while steps S3, S4, and starting the electric balloon inflation pump 102 in step S1 and starting the pulse power supply 101 in step S2 are automatically performed by the controller. Alternatively, in manual mode, all operations in the above steps S1, S2, S3, and S4 are performed after the doctor issues an instruction.

[0057] When placed in automatic mode, after the controller issues a start command, the above steps S1, S2, S3, and S4 can all be automatically operated by the controller; for example, in step S2, in response to the pressure of the balloon 2 in the folded state reaching a first pressure threshold and the electric balloon inflation pump 102 being in the off state, the controller starts the pulse power supply 101.

[0058] The balloon decompression described in this embodiment provides two implementation methods:

[0059] Mode 1: The electric balloon pressure pump 102 can complete the inflation and depressurization of the balloon 2; the electric balloon pressure pump 102 has a first operating state and a second operating state; in the first operating state, the electric balloon pressure pump 102 is used to inflate the balloon 2; in the first operating state, the electric balloon pressure pump 102 is used to depressurize the balloon 2;

[0060] Mode 2: The electric balloon inflation pump 102 is used to inflate the balloon 2 ; the pressure relief valve is used to discharge the fluid in the balloon 2 .

[0061] The electric balloon inflation pump 102 may be driven by a motor, hydraulically, or pneumatically, and may be a syringe pump, a screw pump, or others, which is not limited in this application.

[0062] Optionally, the pressure relief valve is also used for pressure protection of the balloon 2. In response to the pressure of the balloon 2 being greater than a fourth pressure threshold, the pressure relief valve is switched from a closed state to an open state; wherein the fourth pressure threshold is greater than the second pressure threshold. For example, if the bursting pressure of the balloon 2 is 30 atm, the fourth pressure threshold can be set to 27 atm; in response to the pressure of the balloon 2 being greater than 27 atm, the pressure relief valve is automatically switched from a closed state to an open state, so that the balloon 2 is depressurized.

[0063] In this embodiment, the completion of step S1, step S2, step S3, and step S4 is considered to complete a round of shock wave therapy. The pulse power supply 101 applies a pulse voltage to the electrode pair, so that the electrode pair discharges in the liquid of the balloon 2; the discharge generates bubbles in the liquid of the balloon 2, and the bubbles generated after multiple discharges accumulate in the liquid, causing the impedance of the liquid to change, thereby hindering the effective transmission of the shock wave, making it difficult for the shock wave to break up the calcified plaque, and the treatment effect is not ideal.

[0064] Therefore, in step S2 of this embodiment, the pulse power supply 101 sends a preset number of pulse voltages, or the duration of the pulse voltage sent by the pulse power supply 101 reaches a first preset duration, and the pulse power supply 101 is turned off; and in step S4, the electric balloon inflation pump is started to discharge the liquid in the balloon 2, so that the balloon 2 is depressurized to a folded state.

[0065] After step S4 is completed, the doctor evaluates the treatment effect. If the expected treatment effect is achieved, the balloon 2 can be withdrawn and the treatment is terminated. If the expected treatment effect is not achieved, the doctor sends a start command through the controller, and the controller executes step S1, injects new liquid into the folded balloon 2 to pressurize it, and then performs another round of shock wave treatment.

[0066] Specifically, when the controller includes a pulse power control key 1031 and an electric balloon inflation pump control key 1032, after step S4 is completed, the doctor operates the electric balloon inflation pump control key 1032 to make the controller start to execute step S1.

[0067] When the controller includes a main control key 1033, after step S4 is completed, the doctor operates the main control key to make the controller start executing step S1.

[0068] In order to improve the safety of the device, this embodiment also provides the following optional solutions:

[0069] In step S1 of this embodiment, optionally, the electric balloon pressure pump 102 is started, and after the time for charging the balloon 2 in the folded state reaches the third preset time, if the pressure of the balloon 2 does not reach the first pressure threshold, there may be leakage of the balloon 2 or other fault conditions, and the controller stops the electric balloon pressure pump 102 from charging the balloon 2 to facilitate the doctor to check the equipment or end the treatment. For example, under normal conditions, the electric balloon pressure pump 102 is started, and after charging the balloon 2 in the folded state for 5 seconds, the balloon 2 can reach the first pressure threshold; the third preset time can be set to 10 seconds, and after starting the electric balloon pressure pump 102, after charging the balloon 2 in the folded state for 10 seconds, if the balloon 2 still does not reach the first pressure threshold, the controller automatically starts the electric balloon pressure pump 102 to depressurize the balloon 2 to the folded state, or stops the electric balloon pressure pump 102 from charging the balloon 2.

[0070] In step S2 of this embodiment, optionally, when the pressure of the balloon 2 is lower than a third pressure threshold, the controller disables the pulse power supply 101; wherein the third pressure threshold is less than the first pressure threshold. For example, if the first pressure threshold is 4atm, the third pressure threshold is set to 3atm; when the pressure of the balloon 2 is lower than 3atm, the balloon 2 may have a fault such as leakage, and the risk of discharging by turning on the pulse power supply 101 is very high, so the controller disables the pulse power supply 101.

[0071] In step S3 of this embodiment, the electric balloon inflation pump is started. After the duration of inflation of the balloon 2 reaches a fourth preset duration, if the pressure of the balloon 2 does not reach the second pressure threshold, the controller stops the electric balloon inflation pump 102 from inflation of the balloon 2.

[0072] Optionally, the controller further includes a reset button; in response to a reset instruction issued by the operator through the reset button, the controller turns off the pulse power supply 101 and depressurizes the balloon 2 to a folded state. In the event of an abnormal situation, the doctor can quickly turn off the pulse power supply 101 through the reset button to minimize the risk; the balloon 2 can also be depressurized to a folded state to withdraw the balloon 2 from the patient's body to end the treatment or prepare for the next round of treatment.

[0073] Another embodiment of the present application provides Figures 1 to 3A shock wave balloon catheter device is shown, comprising a catheter, a balloon 2 sealed around the outer circumference of the catheter, and at least one electrode pair arranged in the balloon 2; the device also includes the above-mentioned medical equipment; the pulse power supply 101 is used to send a pulse voltage to the electrode pair; the electric balloon inflation pump 102 is used to deliver liquid to the balloon 2 for inflation, and to discharge the liquid in the balloon 2 for pressure relief; when the pulse power supply 101 applies voltage to the electrode pair, the electrode pair can generate a discharge arc in the liquid in the balloon 2.
