摘　　要：本研究旨在开发一款基于虚拟现实技术的先天性心脏病手术模拟器,并对其在提高医生和医学生手术技能方面的有效性进行评估。首先,详细介绍了模拟器的设计原则、虚拟现实技术选型以及具体实现方法,包括基于解剖学的心脏模型构建、手术器械与手术操作的建模、手术过程的动态模拟以及交互界面与用户体验设计。接着,设计了一套评估方法,包括评估目标、实验设计、数据收集与处理以及结果分析方法。实验结果显示,在模拟器操作后,参与者在手术技能评估分数上均有显著提高,特别是对于医学生群体。此外,模拟器在处理不同类型的先天性心脏病手术时都表现出较好的适用性。然而,模拟器在虚拟现实技术本身的局限、部分组织材料属性和生物力学模型的不完善等方面仍存在一些不足。未来研究可从改进硬件性能、生物力学模型、手术类型和病例以及与远程教育和协作系统相结合等方面进行优化,进一步提高模拟器在医学教育和医疗行业的应用价值。The aim of this study is to develop a virtual reality-based congenital heart disease surgery simulator and to evaluate its effectiveness in improving the surgical skills of physicians and medical students.First,the paper discusses in detailed the design principles,virtual reality technology selection and specific implementation methods of the simulator,including anatomy-based heart model construction,modeling of surgical instruments and surgical operations,dynamic simulation of surgical procedures,and interactive interface and user experience design.Then,the paper designs a set of evaluation methods,including evaluation objectives,experimental design,data collection and processing,and result analysis methods.The experimental results show that after the simulator operation,their surgical skill assessment scores of the participants have been significantly improved,especially for the medical student group.In addition,the simulator shows good applicability in handling different types of congenital heart surgery.However,the simulator still has limitations in terms of the limitations of the virtual reality technology itself,the properties of some tissue materials and the imperfections of the biomechanical model.Future research can be optimized in terms of improved hardware performance,biomechanical models,types of surgeries and cases,and integration with distance education and collaboration systems to further improve the value of the simulator for applications in medical education and the healthcare industry.
