The invention discloses a device, system and method for simultaneously carrying out OCT imaging and pressure measurement in a blood vessel. The device comprises an imaging and pressure measurement catheter and a driving control mechanism, wherein the imaging and pressure measurement catheter comprises a catheter optical fiber and an optical fiber probe which are connected, a transmission shaft is arranged outside the catheter optical fiber, an optical fiber end surface of the optical fiber probe is provided with a spherical lens and a light-permeable element, and a pressure sensor is arranged at an end of the optical fiber probe; the driving control mechanism comprises a rotary control unit and a retracement unit, and the rotary control unit is connected with the catheter optical fiber and an external optical fiber and controls the transmission shaft to drive the optical fiber probe to rotate; the retracement unit controls the optical fiber probe to move in the radial direction of the blood vessel through the transmission shaft. The device, system and method for simultaneously carrying out OCT imaging and pressure measurement in the blood vessel can measure blood vessel inner wall morphology images and pressure in the blood vessel in the same catheter.
Description
technical field [0001] The invention relates to the field of cardiovascular detection, in particular to a device, system and method for simultaneously performing OCT imaging and pressure measurement in blood vessels. Background technique [0002] Coronary artery disease (CAD) is the number one cause of death worldwide. Coronary artery disease (CAD) can cause chest pain (angina), myocardial ischemia, and sudden cardiac death due to the buildup, rupture, and thrombus of atherosclerotic plaque. For those patients without sudden death or symptoms of chronic angina, appropriate plaque therapy includes percutaneous coronary intervention (PCI). Interventional cardiologists place stents through PCI to treat lesions. However, in recent years, many studies have concluded that cardiac stents have been abused, or at least overused, causing a lot of controversy. Doctors are more cautious and picky when considering only using stents. In addition, as less costly drug treatments have been...
