Description

technical field [0001] The invention relates to a blood vessel diagnostic instrument, in particular to an intravascular ultrasonic diagnostic instrument with a rotating coupling structure. Background technique [0002] Intravascular Ultrasound (IVUS) is a new diagnostic method combining non-invasive ultrasound technology and minimally invasive catheter technology. Intravascular ultrasound is to use catheter technology to introduce a high-frequency micro-ultrasound transducer into the blood vessel cavity for detection, and obtain cross-sectional imaging of each layer of the blood vessel wall to assist clinicians in diagnosing intravascular lesions. [0003] An intravascular ultrasound imaging system consists of three main components, such as figure 1 As shown, an intravascular ultrasound catheter 1 equipped with an ultrasound probe, a retraction / driving device 2 and an ultrasound imaging system 3 are shown. There are two main designs of commercialized IVUS catheters: mechan...
