技术领域technical field
本发明涉及OCT领域，尤其是一种新型OCT导管用接口。The invention relates to the field of OCT, in particular to a novel interface for OCT catheters.
背景技术Background technique
随着激光技术的不断发展，尤其是超快激光技术的发展，一种新的断层扫描成像技术—OCT（optical coherence tomography）发展起来。其利用红外弱光相干光照射待测组织，依据光的相干性产生干涉，采用超外差探测技术，测量反射回来的光强，用于组织表层成像。具有无辐射、非侵入、高分辨率及高探测灵敏度的特点。在心血管系统中，用于活体获得与心脏结构和功能有关的定性、定量信息，如节拍率、室壁位置、心脏收缩和舒张期间心室容积等；还可用于临床鉴别动脉粥样硬化及用于诊断血管内由于动脉粥样硬化而导致的血管堵塞及破裂情况。在临床应用中OCT设备需搭配OCT导管使用，导管一端连接OCT设备的旋转回撤装置，另一端进入血管等病灶区域进行扫描，获得血管壁的成像特征以进行疾病的诊断。With the continuous development of laser technology, especially the development of ultrafast laser technology, a new tomographic imaging technology—OCT (optical coherence tomography) has been developed. It uses weak infrared coherent light to irradiate the tissue to be tested, and generates interference based on the coherence of the light, and uses superheterodyne detection technology to measure the reflected light intensity for tissue surface imaging. It has the characteristics of no radiation, non-invasive, high resolution and high detection sensitivity. In the cardiovascular system, it is used to obtain qualitative and quantitative information related to cardiac structure and function in vivo, such as beat rate, ventricular wall position, ventricular volume during systole and diastole, etc.; it can also be used for clinical identification of atherosclerosis and for Diagnosis of blood vessel blockage and rupture caused by atherosclerosis in blood vessels. In clinical applications, OCT equipment needs to be used with OCT catheters. One end of the catheter is connected to the rotary retraction device of the OCT equipment, and the other end enters the lesion area such as blood vessels for scanning, and the imaging characteristics of the blood vessel wall are obtained for disease diagnosis.
OCT导管接口作为导管结构中的一部分，用来与设备接口连接，并使得导管被设备识别，从而利用设备驱动导管探头进行扫描成像。但目前现有的OCT导管接口存在与设备接口、旋转芯轴配合不良的现象，致使扫描成像过程中导管因驱动设备高速旋转而发生较大物理性抖动，影响成像质量的同时也给患者造成不适感。另外，手术过程中医生手持OCT导管接口，将导管接口插入设备接口，顺时针旋转一定角度使导管固定，目前由于医生戴手套操作，极易发生手持导管接口旋转打滑现象。这些问题，均限制了OCT导管使用效果，为此我们提出了一种新型OCT导管用接口。As a part of the catheter structure, the OCT catheter interface is used to connect with the device interface and make the catheter recognized by the device, so that the device can be used to drive the catheter probe for scanning and imaging. However, the existing OCT catheter interface has poor coordination with the equipment interface and the rotating mandrel, which causes the catheter to vibrate physically due to the high-speed rotation of the driving device during the scanning imaging process, which affects the imaging quality and causes discomfort to the patient. sense. In addition, during the operation, the doctor holds the OCT catheter interface, inserts the catheter interface into the device interface, and rotates the catheter at a certain angle clockwise to fix the catheter. Currently, because the doctor wears gloves to operate, it is very easy to rotate and slip the handheld catheter interface. These problems limit the use effect of OCT catheters, so we propose a new interface for OCT catheters.
