基于虚拟现实（VR）的模拟技术为传统手术培训提供了一种高效、低成本的替代方案。本文介绍了一种用于腹腔镜直肠手术的VR培训和评估系统。方法提出了一种基于广义圆柱体的碰撞检测方法和多层质量-弹簧模型，使膜组织与手术工具之间的相互作用更加逼真。并设计了一种用于分层训练评价的动态评价模型。结果该模拟器可使受训者在虚拟直肠上同时获得视觉和触觉反馈。该系统还可以在发生不当操作时实时向外科医生提供指导。该模拟器已由10名受试者进行了测试和评估。该原型系统已通过试点研究得到结直肠外科医生的验证。他们相信视觉表现和触觉反馈是真实的。它展示了有效提高实习外科医生的手术技能并显着缩短他们的学习曲线的潜力。版权所有：John Wiley & Sons， Ltd。
BackgroundVirtual-reality (VR) based simulation techniques offer an efficient and low cost alternative to conventional surgery training. This article describes a VR training and assessment system in laparoscopic rectum surgery.MethodsTo give a realistic visual performance of interaction between membrane tissue and surgery tools, a generalized cylinder based collision detection and a multi-layer mass-spring model are presented. A dynamic assessment model is also designed for hierarchy training evaluation.ResultsWith this simulator, trainees can operate on the virtual rectum with both visual and haptic sensation feedback simultaneously. The system also offers surgeons instructions in real time when improper manipulation happens. The simulator has been tested and evaluated by ten subjects.ConclusionsThis prototype system has been verified by colorectal surgeons through a pilot study. They believe the visual performance and the tactile feedback are realistic. It exhibits the potential to effectively improve the surgical skills of trainee surgeons and significantly shorten their learning curve. Copyright (c) 2014 John Wiley & Sons, Ltd.
