Bundled shock wave balloon dilatation catheter with multiple balloons

The multi-balloon cluster shock wave balloon dilatation catheter sequentially comprises a tip, balloons, a dilatation catheter body and a handle base from the far end to the near end, each balloon is composed of three annularly-distributed balloon bodies, the three balloon bodies are attached to one another, a concave part is formed between the peripheries of every two adjacent balloon bodies, the concave parts form a blood circulation channel, and the dilatation channel is communicated with the tip. The far end of the dilation catheter penetrates through the three sacculus bodies and is connected with the tip end of the far end, supporting rods are arranged at the near end and the far end of each sacculus body, the supporting rod at the far end is inserted between the tip end and the dilation catheter and is fixed, and the supporting rod at the near end is fixedly connected with the outer wall of the dilation catheter. Compared with the prior art, after the balloon is filled, a calcified part is crushed thro
