在颅底手术中，外科医生对病人个体解剖结构的了解是至关重要的。培训生和经验丰富的外科医生可以受益于手术模拟；然而，目前的模型价格昂贵，难以广泛使用。在这项研究中，我们报告了下一代混合现实手术模拟器。我们将关键解剖结构分割成三维（3D）模型，以开发模块化教学工具。然后，我们开发了一个导航跟踪系统，利用3d打印内窥镜作为可跟踪的虚拟现实（VR）控制器，并验证了VR和3d打印头骨模型在1厘米内的准确性。我们将虚拟现实和增强现实视觉线索与我们的3D物理模型结合起来，模拟鼻窦内窥镜并实时突出分割结构。该报告提供的证据表明，结合VR和3d打印模型的混合现实模拟器是可行的，并且可能被证明是一种低成本和可定制的教育工具。
The surgeon's knowledge of a patient's individual anatomy is critical in skull base surgery. Trainees and experienced surgeons can benefit from surgical simulation; however, current models are expensive and impractical for widespread use. In this study, we report a next-generation mixed-reality surgical simulator. We segmented critical anatomic structures for 3-dimensional (3D) models to develop a modular teaching tool. We then developed a navigation tracking system utilizing a 3D-printed endoscope as a trackable virtual-reality (VR) controller and validated the accuracy on VR and 3D-printed skull models within 1 cm. We combined VR and augmented-reality visual cues with our 3D physical model to simulate sinus endoscopy and highlight segmented structures in real time. This report provides evidence that a mixed-reality simulator combining VR and 3D-printed models is feasible and may prove useful as an educational tool that is low cost and customizable.
