Abstract

The invention discloses an intravascular ultrasonic diagnosis system and a magnetic driving method. The intravascular ultrasonic diagnosis system comprises a catheter component, an ultrasonic transducer disposed in the catheter component, a magnetic driving unit disposed in the catheter component, and an external portion arranged outside a diagnosed body. The magnetic driving unit connected with the ultrasonic transducer is used for driving the ultrasonic transducer to rotate. A plurality of magnets are stacked by rotating target magnetic poles at a preset angle to form the magnetic driving unit, and the stacking direction is along the axial direction of the rotating direction. The external portion comprises an alternating magnetic field generation unit formed by arraying a plurality of electromagnetic coils. The alternating magnetic field generation unit is used for generating an alternating magnetic field corresponding to the rotation speed of the ultrasonic transducer. The intravascular ultrasonic diagnosis system and the magnetic driving method have the advantages that the magnets are stacked by rotating the target magnetic poles at a preset angle to form the magnetic driving unit which drives the ultrasonic transducer to rotate synchronously, the magnetic driving unit drives the ultrasonic transducer to rotate smoothly, obtained echo signals are uniform, and the imaging effect is remarkably improved.

Description

technical field [0001] The present application relates to the technical field of intravascular ultrasonic echo imaging, in particular to an intravascular ultrasonic diagnostic system and a magnetic drive method. Background technique [0002] Intravascular ultrasound (intravenous ultrasound, IVUS) technology has brought unprecedented convenience and speed to the diagnosis and treatment of cardiovascular diseases, and has greatly improved the accuracy of judgments on the degree and nature of cardiovascular stenosis. The stent repair treatment plan has more detailed and reliable data parameters. In particular, the advantages in the composition of vulnerable plates in blood vessels and the severity of atherosclerosis are in-depth effects that cannot be achieved by other diagnostic techniques. [0003] The intravascular ultrasonic diagnostic system uses a metal wire hose of about 1.6 meters as the drive shaft, which is inserted into the blood vessel in the body from the lower li...
