Description

technical field [0001] The invention relates to an intravascular ultrasonic imaging retraction device, which belongs to the technical field of medical devices. Background technique [0002] Intravascular ultrasound (IVUS) refers to the combination of non-invasive ultrasound technology and invasive catheter technology, using a special catheter with an ultrasound probe attached to the end of the medical imaging technology. Intravascular ultrasound is to place a miniaturized ultrasonic transducer into the cardiovascular cavity through a cardiac catheter to display the cross-sectional shape of the cardiovascular system and (or) blood flow patterns, mainly including ultrasound imaging technology and Doppler blood flow measurement . On the basis of angiographic examination, select the blood vessel and lesion site to be examined, take the coronary artery as an example, guide the catheter to the coronary artery, send the guide wire to the distal end of the target blood vessel, and ...
