The invention relates to the technical field of medical equipment, and discloses blood vessel expansion equipment. The blood vessel expansion equipment comprises an expansion stent, a monitor, a dataprocessor and an electromagnetic suspension driving assembly; the expansion stent has the shrinkage form and the expansion form and is used for excising thromboses and expanding the blood vessels; themonitor is used for detecting the position and the form of the expansion stent, and generating data signals according to the detected position and form; the data processor is in signal connection with the monitor and is used for generating control signals according to the data signals; the electromagnetic suspension driving assembly is in signal connection with the data processor and is used fordriving the expansion stent to move according to the control signals and driving the expansion stent to be switched into the expansion form from the shrinkage form according to the control signals. The diameter of the expansion stent in the blood vessel expansion equipment in the shrinkage form can be made smaller, the blood vessel expansion equipment can be applied to thrombosis treatment of medium and small arteries and veins, and the influence of the initial guiding-in position of the expansion stent on a patient is smaller.
