腹腔镜手术是一种复杂的微创手术，新学员需要较长的学习曲线才能拥有足够的经验才能成为一名合格的外科医生。随着虚拟现实技术的发展，基于虚拟现实的手术模拟在手术训练中发挥着越来越重要的作用。腹腔镜手术的模拟具有较大的非线性软组织变形、频繁的手术工具相互作用和复杂的解剖环境，因此具有挑战性。目前的研究主要集中在非常具体的主题（例如变形和碰撞检测），而不是一致且有效的框架。直接使用现有方法无法同时获得较高的视觉/触觉质量和令人满意的刷新率，特别是对于复杂的手术模拟。在本文中，我们提出了一套量身定制的腹腔镜手术模拟关键技术，从不同属性的软组织的模拟，到手术工具与软组织之间的相互作用，再到复杂解剖环境的渲染。与现有方法相比，我们定制的算法旨在从准确性、稳定性和效率的角度提高性能。我们还抽象并设计了一组直观的参数，可以为开发人员提供高度的灵活性来开发自己的模拟器。版权所有 (C) 2016 约翰·威利父子有限公司
Laparoscopic surgery is a complex minimum invasive operation that requires long learning curve for the new trainees to have adequate experience to become a qualified surgeon. With the development of virtual reality technology, virtual reality-based surgery simulation is playing an increasingly important role in the surgery training. The simulation of laparoscopic surgery is challenging because it involves large non-linear soft tissue deformation, frequent surgical tool interaction and complex anatomical environment. Current researches mostly focus on very specific topics (such as deformation and collision detection) rather than a consistent and efficient framework. The direct use of the existing methods cannot achieve high visual/haptic quality and a satisfactory refreshing rate at the same time, especially for complex surgery simulation. In this paper, we proposed a set of tailored key technologies for laparoscopic surgery simulation, ranging from the simulation of soft tissues with different properties, to the interactions between surgical tools and soft tissues to the rendering of complex anatomical environment. Compared with the current methods, our tailored algorithms aimed at improving the performance from accuracy, stability and efficiency perspectives. We also abstract and design a set of intuitive parameters that can provide developers with high flexibility to develop their own simulators. Copyright (C) 2016 John Wiley & Sons, Ltd.
