A vortex catheter thrombolytic system comprises an ultrasonic transducer; and a probe for transmitting a vortex acoustic field as well as a catheter, wherein the catheter is arranged in the probe for transmitting the vortex acoustic field, is connected to the ultrasonic transducer and is provided with a first inner channel and a second inner channel, the first inner channel is used for delivering drugs, and the second inner channel is used for vortex driving. A thrombolytic method comprises: performing an ultrasonic execution step through the vortex catheter thrombolytic system so as to generate an acoustic vortex; executing a focusing step so as to focus a drug delivery carrier to the center of the acoustic vortex; and executing a manipulation step so as to manipulate the drug delivery carrier to a lesion area.
