A probe integrating optical coherence tomography and intravascular ultrasound

Abstract

The invention discloses a probe integrating optical coherence tomography and intravascular ultrasound, which belongs to the field of diagnosis; it includes: a catheter, an integrated probe and a spring tube, wherein the proximal end of the casing in the integrated probe is fixedly connected to the spring tube, an optical fiber connector, The integrated frame of the spacer block and the reflector sensor is sequentially fixed in the sleeve from the proximal end to the distal end, and the optical fiber enters the fiber optic connector from the proximal end of the sleeve tube to center the optical fiber; the fiber end face of the optical fiber is bonded to the surface of the proximal end of the spacer block. Fixed connection, the proximal end of the optical fiber is connected to the optical fiber connector in the patient interaction unit, and the lead wire passed by the ultrasonic probe installed in the reflector sensor integrated frame is connected to the ultrasonic connector in the patient interaction unit. In the present invention, the relative positions of the OCT probe and the IVUS sensor are consistent during mass production, which ensures the registration of the two images. And the problem that the relative position is difficult to directly match due to the difference in the way of acousto-optic emission and collection is solved by a single reflector-sensor integrated frame.

Description

Technical field [0001] The present invention belongs to the multi-mode diagnostic techniques, and in particular coherence tomography and intravascular ultrasound probe is an integrated optics, to implement optical coherence tomography (Optical Coherence Tomography, OCT) and IVUS (Intravascular Ultrasound, IVUS) of modality imaging. Background technique [0002] Intravascular Imaging of atherosclerotic coronary heart disease in particular has been widely used, wherein the imaging system is most commonly used intravascular ultrasound (IVUS), and optical coherence tomography (OCT). Both of which are applied within the coronary imaging catheter to image coronary artery cross-section, the two different imaging principles advantage to have different imaging. Since IVUS tissue penetration ability is superior OCT, identification of blood vessels can be achieved in the wall thickness, the axial resolution of the OCT IVUS is 10 times, the identification plaque microstructure can be realize...
