1. A discharge controllable shock wave balloon catheter system, comprising:
a shock wave therapy main unit (1),
a balloon (2),
a catheter, and
a plurality of electrode pairs (6);
wherein an end of the catheter is arranged passing through the balloon (2), and an other end of the catheter is connected to the shock wave therapy main unit (1); the plurality of electrode pairs (6) are accommodated in the balloon (2) and mounted on the catheter; the plurality of electrode pairs (6) are arranged to be spaced apart along a length direction of the catheter; each of the plurality of electrode pairs (6) is independently connected to the shock wave therapy main unit (1), and the plurality of electrode pairs (6) are not connected to each other;
wherein the shock wave therapy main unit (1) comprises a plurality of pulse switch modules, each of the plurality of pulse switch modules is independently connected, and a number of the plurality of pulse switch modules is less than or equal to a number of the plurality of electrode pairs (6); one of the plurality of pulse switch modules is electrically connected to one of the plurality of electrode pairs (6) by a metal wire in a one-to-one correspondence, or one of the plurality of pulse switch modules is electrically connected to two or more of the plurality of electrode pairs (6) by metal wires; and a magnitude and a frequency of a shock wave energy released by each of the plurality of electrode pairs controlled by a corresponding pulse switch module are different.
