The utility model relates to a multifunctional balloon dilatation catheter which comprises an internal catheter internally provided with a guide wire passage, an external catheter coaxially arranged with the internal catheter and a dilatation balloon and further comprises occlusion balloons arranged at intervals from the dilatation balloon and fixed on the external catheter, wherein a low-pressure transfer passage, a high-pressure transfer passage and a suction passage are radially formed between the external catheter and the internal catheter; and Luer fittings are mounted at outlet ends of the low-pressure transfer passage, the high-pressure transfer passage, the suction passage and the guide wire passage respectively. According to the catheter, balloon dilatation is performed in a PCI (Percutaneous Coronary Intervention) operation, and at the same time, fine plaques falling from a lesion are trapped in a sealed space formed by the occlusion balloons, the dilatation balloon and a blood vessel wall and extracted timely; during the operation, the balloon dilatation and thrombus suction are accomplished at one time without replacing a device; and the exchange frequency of the medical device in a patient body is reduced, so that complications caused by blood vessel injuries of a patient are reduced.
