Abstract

The invention belongs to the field of vascular endoscopic imaging, and discloses a rapid plug type photocoupling joint for a photoacoustic ultrasonic intravascular imaging system. The joint structurally comprises a pre-embedded rapid optical fiber cold joint, a pin jack type joint, a plug type joint housing, a metal shielding housing and a bearing. The pre-embedded rapid optical fiber cold joint is used for coupling transmission of a photoacoustic excitation optical path; the pin jack type joint is used for coupling transmission of an ultrasonic transmission receiving / photoacoustic signal receiving circuit; the plug type joint housing is used for integrating the pre-embedded rapid optical fiber cold joint and the pin jack type joint to implement a trinity synchronous plug function; the metal shielding housing is used for protecting the joint and shielding signal interference of noise to circuit coupling; and the bearing is used for implementing coaxial rotation of the joint and reducing mechanical friction when the joint and a rotating scanning device are matched for use.

Description

technical field [0001] The invention relates to the technical field of vascular endoscopy, and relates to a quick plug-in photoelectric coupling joint used in a photoacoustic ultrasound intravascular imaging system. Background technique [0002] Entering the 21st century, cardiovascular and cerebrovascular diseases have become the number one killer affecting human health, and the rupture of atherosclerotic plaques is the main cause of acute cardiac vascular events. Ultrasound imaging, intravascular optical coherence tomography, intravascular photoacoustic imaging, etc.) have also developed rapidly. Among them, intravascular ultrasonic imaging and intravascular optical coherence tomography have a relatively mature imaging system. An ultrasonic signal coupling transmission joint and a laser coupling transmission joint are respectively arranged between the rotating scanning device and the rotating scanning device, so as to realize the transfer coupling of the electrical signal ...
