Abstract

Disclosed is an electrode of a shock wave balloon apparatus, comprising a first electrode set and a wire for electrically connecting the first electrode set. The first electrode set comprises a first electrode, a second electrode, and a third electrode that are sequentially arranged apart side by side. The wire is further electrically connected to an electrode control module to form a shock wave between the first electrode and the second electrode and a shock wave between the second electrode and the third electrode. Embodiments of the present invention use the electrode of the shock wave balloon apparatus composed of the first electrode, the second electrode, and the third electrode that are arranged apart side by side. The shock wave gap is formed by the arrangement of an axial distance of the electrodes, thereby greatly reducing the contour of the folded balloon and avoiding the issue that the radial gap arrangement used in existing shock wave balloon apparatuses causes the contour of the folded balloon to be too large to pass through a lesion with a large degree of stenosis. The present invention is ingeniously designed.

TECHNICAL FIELD

[0003] The present application relates to the field of medical technology, and relates to but is not limited to an electrode of a shockwave balloon device, an electrode manufacturing method and a shockwave balloon device. BACKGROUND

[0004] At present, the treatment of arterial calcified plaque leading to vascular stenosis often uses shockwave balloon for pretreatment. The shockwave balloon can effectively crack and push the calcified plaque into the arterial wall, thereby providing more space for subsequent stent implantation and ensuring the complete opening of the stent, effectively reducing the rate of vascular restenosis and improving the success rate of surgery. Therefore, shockwave balloon treatment for severe calcified vascular recanalization has significant clinical significance. However, the existing electrodes of the shockwave balloon are arranged in a radial superposition, which greatly increases the folding profile of the balloon catheter, making it unable to pass through lesions with a large degree of stenosis. In order to enable the shockwave balloon catheter to effectively pass through the lesion site, a grinding device is often needed to grind part of the stenosis plaque, which also increases the difficulty and complications of the surgery. At the same time, the existing shockwave balloon is designed to be very thin to reduce the folding profile of the balloon, which greatly reduces the corrosion resistance of the electrode, resulting in poor shockwave stability and low efficiency of calcified plaque fragmentation. In addition, the shockwave balloon needs to be used with a pulse generator, which is large in size and relatively fixed in position, which is not conducive to the movement and operation of the doctor, thereby increasing the operation time and risk.

[0090] In an embodiment, the first switch tube Q11 and the second switch tube Q12 can be N-type MOS tubes, in which case the first end of the first switch tube Q11 and the second switch tube Q12 is the gate, the second end is the drain, and the third end is the source.

[0091] Exemplarily, referring to FIG. 14, the first end of the first switch tube Q11 is electrically connected to the power module 101 through the parallel connection of the voltage dividing resistor R51 and the voltage dividing resistor R54; and the first end of the second switch tube Q12 is electrically connected to the power module 101 through the parallel connection of the voltage dividing resistor R52 and the voltage dividing resistor R55.

[0092] In the embodiment of the present application, the power module 101 is connected to the first end of the first switch tube Q11 and the second switch tube Q12, and is configured to control the working state of the first switch tube Q11 and the second switch tube Q12. Exemplarily, the power module 101 outputs a PWM control signal to the first switch tube Q11 and the second switch tube Q12, and the first switch tube Q11 and the second switch tube Q12 are in a closed state when the PWM control signal is at a high level, and are in an open state when the PWM control signal is at a low level.

[0093] In some embodiments, referring to FIG. 14, the drive circuit 102 further comprises a feedback circuit, which comprises a comparator U1, the positive input end of the comparator U1 being connected to the input end of the current sensing resistor R53 (corresponding to I_T in FIG. 10), the negative input end being connected to a reference voltage VREF, and the output end being connected to the power module 101. Exemplarily, the reference voltage VREF is a reference voltage provided by a power management chip in the power module 101; the negative input end of the comparator U1 is connected to the reference voltage VREF, that is, the voltage at the negative input end of the comparator U1 is the reference voltage VREF.

[0094] Exemplarily, as can be seen from FIG. 14, when the first switch tube Q11 and the second switch tube Q12 are in a closed state, the source current of the first switch tube Q11 and the second switch tube Q12 flows through the current detection resistor R53, a voltage is generated on the current detection resistor R53, and the voltage is the positive input voltage of the comparator U1; after obtaining the positive input voltage, the comparator U1 compares the positive input voltage with the reference voltage VREF, and controls the level state of the voltage signal output to the power module 101 according to the comparison result; and the power management chip in the power module 101 can control whether to cut off the output of the PWM control signal according to the level state of the voltage signal.

[0095] Understandably, when the current flowing through the current detection resistor R53 is abnormally large, the voltage generated on the current detection resistor R53 will also increase, that is, the positive input voltage of the comparator U1 will increase, at this time, the positive input voltage of the comparator U1 is greater than the reference voltage VREF, the voltage signal output to the power module 101 by the comparator U1 will be flipped from low level to high level, and the power management chip will cut off the output of the PWM control signal when detecting that the voltage signal is flipped from low level to high level, thereby protecting the first boost circuit 10; at this time, the first switch tube Q11 and the second switch tube Q12 cannot receive the PWM control signal output by the power module 101.

[0096] As can be seen, in the embodiment of the present application, by arranging the current detection resistor R53 and the feedback circuit in the first boost circuit, the circuit can be quickly switched when the first boost circuit 10 is in an abnormal condition, and the safety of the boost process is ensured.

[0097] In the embodiment of the present application, the power module 101, the first switch tube Q11, the second switch tube Q12 and the transformer 103 constitute a push-pull boost circuit. In some embodiments, referring to FIG. 14, the transformer 103 includes a primary coil and a secondary coil, the primary coil includes a first coil T1 and a second coil T2, the second end of the first coil T1 is connected to the second end of the first switch tube Q11 with respect to the same name end of the secondary coil, and the opposite name end of the first coil T1 is connected to the input voltage VCC with respect to the secondary coil; the second end of the second coil is connected to the second end of the second switch tube with respect to the opposite name end of the secondary coil, and the same name end of the second coil is connected to the input voltage VCC with respect to the secondary coil.

[0098] In the embodiment of the present application, when the first switch tube Q11 and the second switch tube Q12 are in a closed state, a driving signal can be generated according to the PWM control signal, and the driving signal is sent to the primary coil of the transformer 103, at this time, the primary coil of the transformer 103 generates a voltage, so that the secondary coil of the transformer 103 generates a voltage, therefore, by controlling the frequency and duty cycle of the PWM control signal, the input voltage VCC can be boosted to different amplitudes.

[0099] In some embodiments, referring to FIG. 14, the first voltage boosting circuit includes a rectifier circuit 105, an input end of the rectifier circuit 105 is connected with the secondary coil, and an output end of the rectifier circuit 105 is connected with an input end of the second voltage boosting circuit 11; for example, the rectifier circuit 105 is arranged between the secondary coil of the transformer 103 and the second voltage boosting circuit 11, and can include a plurality of rectifier tubes; the rectifier circuit 105 is used to rectify the alternating current boosted by the transformer 103 into direct current, so as to complete the first-stage voltage boosting process; wherein, the output voltage of the rectifier circuit 105 is the intermediate voltage.

[0100] In some embodiments, referring to FIGS. 13 to 15, the second voltage boosting circuit 11 includes a Marx generator circuit 104, the Marx generator circuit 104 includes a plurality of parallel capacitor branches, one end of each circuit branch is connected with an output end (corresponding to HV in FIG. 14) of the rectifier circuit 105, and the other end is grounded. For example, the Marx generator circuit 104 can further include a plurality of switches respectively connected in parallel with the plurality of capacitor branches; referring to FIG. 15, in the case that the Marx generator circuit 104 includes three parallel capacitor branches, the Marx generator circuit further includes a switch S1, a switch S2 and a switch S3.

[0101] Further, when the switch S1, the switch S2 and the switch S3 are in an open state, the intermediate voltage boosted and rectified by the first voltage boosting circuit 10 charges the capacitor C86, the capacitor C87 and the capacitor C88 in the Marx generator circuit 104 respectively, and the charging voltage value is the intermediate voltage output by the rectifier circuit 105 of the first voltage boosting circuit 10; when the Marx generator circuit 104 works, the switch S1, the switch S2 and the switch S3 are in a closed state, at this time, the capacitor C86, the capacitor C87 and the capacitor C88 are discharged in series, the intermediate voltage is superimposed to three times and output, so as to complete the second-stage voltage boosting process. For example, in the case that the intermediate voltage is 1000V, the intermediate voltage is second-stage boosted by the Marx generator circuit 104 shown in FIG. 15, and the target voltage obtained is 3000V.

[0102] It should be noted that the Marx generator circuit 104 can select a capacitor with a smaller capacitance value, so as to ensure that the second-stage voltage boosting process can be completed, the released energy is not too high, and the stability and reliability of the voltage boosting process are ensured.

[0103] The application provides a high-voltage pulse generation circuit, which comprises a first voltage boosting circuit and a second voltage boosting circuit arranged in cascade, the first voltage boosting circuit comprises a power supply module, a driving circuit and a transformer, one end of the driving circuit is connected with the power supply module, the other end is connected with an input end of the transformer, an output end of the transformer is connected with an input end of the second voltage boosting circuit, and the input end of the transformer is also connected with an input voltage; the driving circuit is configured to receive a PWM control signal output by the power supply module, generate a driving signal according to the PWM control signal, and send the driving signal to the transformer; the transformer is configured to boost the input voltage according to the driving signal, obtain an intermediate voltage, and send the intermediate voltage to the second voltage boosting circuit; and the second voltage boosting circuit is configured to boost the intermediate voltage to obtain a target voltage.

[0104] It can be seen that the high-voltage pulse generation circuit realizes the boosting of the input voltage through a two-stage boosting process, that is, the input voltage is first boosted to an intermediate voltage by the first voltage boosting circuit, and then the intermediate voltage is further boosted to a target voltage by the second voltage boosting circuit; compared with directly using a high-voltage pack or using a large-power transformer to boost the input voltage to the target voltage, the two-stage boosting process can reduce power loss to solve the problem of heating of components, and also improve the stability of the boosting process, effectively improving the reliability and safety of the circuit.
