背景：医学和外科正在转向模拟，以改善住院医师培训期间有限的患者互动。如今，许多模拟器使用具有增强触觉反馈的虚拟现实，几乎没有物理元素。在一项合作努力中，佛罗里达大学神经外科系和安全、模拟和高级学习技术中心创建了一种新颖的“混合”物理和虚拟模拟器，以模拟脑室造口术过程。该模拟器包含了所有的物理组件与叠加的3-D虚拟元素的neurosatomical structures.OBJECTIVE：介绍脑室造口术模拟器和它的验证作为一个必要的培训工具，在神经外科residence.METHODS：我们测试了模拟器在260多名居民。一种结合时间和准确性的算法被用来对性能进行分级。自愿事后调查被用来评估experience.RESULTS：结果表明，更有经验的居民有统计学意义上更好的成绩，并在更短的时间内完成程序比没有经验的居民。调查结果显示，大多数居民同意，在模拟器上的做法将有助于未来ventriculostomies.CONCLUSION：这种混合现实模拟器提供了一个真实的生活经验，并将成为一个工具，在培训下一代的神经外科医生。我们现在已经实施了一个标准，即新来的住院医生在与病人进行第一次互动之前，必须在模拟器上证明他们的效率和技能。
BACKGROUND: Medicine and surgery are turning toward simulation to improve on limited patient interaction during residency training. Many simulators today use virtual reality with augmented haptic feedback with little to no physical elements. In a collaborative effort, the University of Florida Department of Neurosurgery and the Center for Safety, Simulation & Advanced Learning Technologies created a novel "mixed" physical and virtual simulator to mimic the ventriculostomy procedure. The simulator contains all the physical components encountered for the procedure with superimposed 3-D virtual elements for the neuroanatomical structures.OBJECTIVE: To introduce the ventriculostomy simulator and its validation as a necessary training tool in neurosurgical residency.METHODS: We tested the simulator in more than 260 residents. An algorithm combining time and accuracy was used to grade performance. Voluntary postperformance surveys were used to evaluate the experience.RESULTS: Results demonstrate that more experienced residents have statistically significant better scores and completed the procedure in less time than inexperienced residents. Survey results revealed that most residents agreed that practice on the simulator would help with future ventriculostomies.CONCLUSION: This mixed reality simulator provides a real-life experience, and will be an instrumental tool in training the next generation of neurosurgeons. We have now implemented a standard where incoming residents must prove efficiency and skill on the simulator before their first interaction with a patient.
