摘　　要：目前标准的左心耳封堵主要使用X线透视影像和经食道心脏超声等二维成像方式来指导手术进行,这会导致术者对左心耳与周围组织的三维结构信息估计不足,影响手术效果。为解决这一问题,该研究设计了一套基于心脏CT影像的左心耳封堵三维辅助软件系统。该软件系统实现了基于心脏CT影像数据的左心耳参数测量、并在一种全新的输送鞘运动模型的基础上实现了最优输送鞘运动轨迹计算和输送鞘运动三维模拟。该系统有望为左心耳封堵的手术过程提供更加精准的指导,提高手术的成功率和安全性,同时有助于降低手术的学习难度,促进左心耳封堵技术的临床推广应用。At present,the standard left atrial appendage occlusion procedure mainly involves two-dimensional imaging methods such as X-ray fluoroscopy and transesophageal echocardiography to guide the operation,which will lead to underestimation of the three dimensional structure of the left atrial appendage and the surrounding tissue,thus adversely affects the surgery.To solve this problem,a surgery assist system for left atrial appendage occlusion based on preoperative cardiac CT images is developed.The proposed system realizes the left atrial appendage parameter measurement based on cardiac CT image,and realizes the calculation of optimal delivery sheath trajectory and three-dimensional simulation of the delivery sheath movement on the basis of a novel delivery sheath trajectory model.The system is expected to provide precise guidance for left atrial appendage occlusion,improve the success rate and safety of the operation,and at the same time help reduce the difficulty of learning the operation,and facilitate the promotion of left atrial appendage occlusion.
