Ablation catheter, laser ablation system and intravascular laser plaque ablation method

The invention is suitable for the technical field of blood vessel ablation, and provides an ablation catheter, a laser ablation system and an intravascular laser plaque ablation method. The ablation catheter comprises a catheter body and an optical fiber bundle installed in the catheter body, the ablation catheter further comprises a plurality of optical coherence tomography probes, and the optical coherence tomography probes are distributed in the optical fiber bundle at intervals in the circumferential direction of the optical fiber bundle so as to be matched with one another to obtain front signals of the catheter body. The laser ablation system comprises a control module, a coupling module and the ablation catheter connected with the coupling module. The invention further provides an intravascular laser plaque ablation method. According to the ablation catheter, the laser ablation system and the intravascular laser plaque ablation method, plaque ablation can be rapidly and accurately completed, meanwhile,
