AI总结：
针对胸外科VATS套管针放置依赖经验易致方案欠佳的问题，研究推出首款遵循外科原则的VR术前规划工具，经初步验证其高效易用，有临床应用潜力并可为相关系统开发提供参考。
摘要：
电视辅助胸腔镜手术（VATS）是治疗早期非小细胞肺癌的微创术式。VATS术中最优的套管针放置可确保全面进入胸腔、提供全景内镜视野并避免器械拥挤。尽管已有棒球钻石原则（BDP）、三角靶点原则（TTP）等既定原则，外科医生主要依靠经验和患者特异性解剖结构进行套管针放置，可能导致手术方案欠佳，增加手术时间和医生疲劳度。为解决这一问题，我们遵循既定外科原则并经资深外科医生咨询，推出首款基于虚拟现实（VR）的术前规划工具，其配备定制化数据可视化与交互设计，可实现高效、最优的VATS套管针放置。在初步研究中，我们展示了该系统在右上肺叶切除术（一种通常使用三根套管针的常见胸外科手术）中的应用。针对该系统的初步用户研究表明，它在规划最优套管针放置方面高效、稳健且易用，具有良好的临床应用前景，同时可为其他外科VR系统的开发提供潜在的宝贵见解。
英文摘要：
Video-assisted thoracic surgery (VATS) is a minimally invasive approach for treating early-stage non-small-cell lung cancer. Optimal trocar placement during VATS ensures comprehensive access to the thoracic cavity, provides a panoramic endoscopic view, and prevents instrument crowding. While established principles such as the Baseball Diamond Principle (BDP) and Triangle Target Principle (TTP) exist, surgeons mainly rely on experience and patient-specific anatomy for trocar placement, potentially leading to sub-optimal surgical plans that increase operative time and fatigue. To address this, we present the first virtual reality (VR)-based pre-operative planning tool with tailored data visualization and interaction designs for efficient and optimal VATS trocar placement, following the established surgical principles and consultation with an experienced surgeon. In our preliminary study, we demonstrate the system's application in right upper lung lobectomy, a common thoracic procedure typically using three trocars. A preliminary user study of our system indicates it is efficient, robust, and user-friendly for planning optimal trocar placement, with a great promise for clinical application while offering potentially valuable insights for the development of other surgical VR systems.
