Abstract

The invention provides a guide pipe quick fixing and unloading structure which comprises a guide pipe and a mounting seat, and the guide pipe can be inserted into an insertion hole in the mounting seat; an insertion hole is formed in the mounting base, a lock hole is formed in the side wall of the mounting base and communicated with the insertion hole, a lock pin is inserted into the lock hole, and after the guide pipe is inserted into the insertion hole, the lock pin can lock the guide pipe; the lock pin is fixed to a sliding switch, and a reset spring abuts against the lock pin or the sliding switch so as to apply elastic force towards the radial inner side direction of the installation base to the lock pin or the sliding switch. By the adoption of the technical scheme, the quick fixing and dismounting structure for the guide pipe can achieve quick mounting, fixing and dismounting of the guide pipe on the mounting base.

Description

technical field [0001] The invention relates to a fast fixing and unloading structure of a catheter, which belongs to the technical field of medical imaging. 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 pl...
