摘　　要：颈静脉穿刺在临床应用广泛,针对传统训练方法训练资源短缺且不易重复的缺点,本文利用虚拟现实平台构建了一个颈静脉穿刺的初步系统。我们对可能的虚拟现实平台进行了调研,选择了SOFA(Simulation Open Framework Architecture)作为我们的基础平台。利用仿真框架SOFA实现对虚拟手术场景的可视化模型、行为模型和碰撞模型的定义,并将人体头部和手术器械的面模型和体模型导入到虚拟手术场景中,实现了虚拟手术场景的创建,并利用SOFA实现了变形求解。通过构建这个初步系统,证明了利用SOFA构建颈静脉穿刺虚拟手术系统的可行性。Jugular vein puncture is a common practice in clinic. Considering the shortage of traditional training methods and the lack of repetition, this paper constructed a preliminary system of the jugular vein puncture using the virtual reality platform. We surveyed the potential virtual reality platform and chose SOFA （simulation open framework architecture） as our base platform. We conducted a survey of possible virtual reality platforms, consequently chosed SOFA as our basic platform. The visualization model, behavior model and collision model of virtual surgery scene were realized by using the simulation framework SOFA. In addition, the surface model and body model of human head and surgical instruments were imported into the virtual operation scene, the virtual operation scene was created, and the deformation solution was realized by SOFA. The feasibility of using the SOFA to construct the virtual surgery system of jugular vein puncture was proved by this preliminary system.
