The invention discloses an arterial rotary grinding interventional device, which relates to the technical field of arterial rotary grinding. The invention comprises a controller, an electric motor, aspeed regulator, an air pump, a waste liquid tank, a cleaning box and a water pump, wherein the water outlet of the water pump is fixed with a first water pipe, the air outlet of the air pump is fixedwith an air pipe, a rotating thread is fixed at one end of the output shaft of the electric motor, and a liquid discharge pipe is fixed at the liquid inlet of the waste liquid tank. The cleaning liquid in the cleaning box is pumped to a polishing place by a water pump, the flushed waste liquid will flow into the waste liquid tank along the drain pipe, so that the ground debris can be discharged out of the body in time, the air is introduced into the air bag through the air pump along the air pipe. The constricted air bag is stuck on the blood vessel wall, and the conical grinding head is supported and fixed. The sliding key in the speed governor is controlled by hand, so that the motor is adjusted to the proper rotational speed. The surface of the speed governor is scaled, so that the rotational speed of the motor can be known in time, and the arterial rotary grinding intervene device is convenient to operate.
