Surgical simulators are powerful tools that assist in providing advanced training for complex craniofacial surgical procedures and objective skills assessment such as the ones needed to perform Bilateral Sagittal Split Osteotomy (BSSO). One of the crucial steps in simulating BSSO is accurately cutting the mandible in a specific area of the jaw, where surgeons rely on high fidelity visual and haptic cues. In this paper, we present methods to simulate drilling and cutting of the bone using the burr and the motorized oscillating saw respectively. Our method allows low computational cost bone drilling or cutting while providing high fidelity haptic feedback that is suitable for real-time virtual surgery simulation.
手术模拟器是强大的工具，有助于为复杂的颅面外科手术提供高级培训，并进行客观的技能评估，例如进行双侧矢状劈开截骨术（BSSO）所需的技能评估。模拟BSSO的关键步骤之一是在颌骨的特定区域精确切割下颌骨，在此过程中外科医生依赖高保真视觉和触觉线索。在本文中，我们分别介绍了使用磨头和电动摆锯模拟骨钻孔和切割的方法。我们的方法允许以低计算成本进行骨钻孔或切割，同时提供适用于实时虚拟手术模拟的高保真触觉反馈。
