随着手术治疗的脑动脉瘤数量的减少和手术治疗复杂性的增加，需要基于模拟的工具来教授未来的神经外科医生动脉瘤夹闭术的手术技术。开发和评估一种新的基于触觉的虚拟现实（VR）模拟器在神经外科住院医师培训中的有用性。利用Immersive Touch平台开发了一个实时感觉触觉反馈虚拟现实动脉瘤夹闭模拟器。一个原型大脑中动脉瘤模拟创建的计算机断层扫描血管造影。在3-D沉浸式VR环境中提供动脉瘤和血管体积变形和触觉反馈。还模拟了术中动脉瘤破裂。来自三个住院医师项目的17名神经外科住院医师测试了模拟器，并就其实用性和与真实的动脉瘤夹闭手术的相似性提供了反馈。居民们认为，模拟将有助于为现实生活中的手术做准备。大约三分之二的住院医师认为三维沉浸式解剖细节提供了与真实的手术解剖非常相似的地方，并为决定手术入路提供了准确的指导。他们认为该模拟对于术前手术排练和神经外科培训很有用。三分之一的住院医生认为，目前形式的技术为动脉瘤手术提供了非常逼真的触觉反馈。神经外科住院医师认为，新颖的沉浸式VR模拟器对他们的培训很有帮助，特别是因为他们直到住院医师计划的后期才有机会进行动脉瘤切除术。
With the decrease in the number of cerebral aneurysms treated surgically and the increase of complexity of those treated surgically, there is a need for simulation-based tools to teach future neurosurgeons the operative techniques of aneurysm clipping. To develop and evaluate the usefulness of a new haptic-based virtual reality (VR) simulator in the training of neurosurgical residents. A real-time sensory haptic feedback virtual reality aneurysm clipping simulator was developed using the Immersive Touch platform. A prototype middle cerebral artery aneurysm simulation was created from a computed tomography angiogram. Aneurysm and vessel volume deformation and haptic feedback are provided in a 3-D immersive VR environment. Intraoperative aneurysm rupture was also simulated. Seventeen neurosurgery residents from three residency programs tested the simulator and provided feedback on its usefulness and resemblance to real aneurysm clipping surgery. Residents felt that the simulation would be useful in preparing for real-life surgery. About two thirds of the residents felt that the 3-D immersive anatomical details provided a very close resemblance to real operative anatomy and accurate guidance for deciding surgical approaches. They believed the simulation is useful for preoperative surgical rehearsal and neurosurgical training. One third of the residents felt that the technology in its current form provided very realistic haptic feedback for aneurysm surgery. Neurosurgical residents felt that the novel immersive VR simulator is helpful in their training especially since they do not get a chance to perform aneurysm clippings until very late in their residency programs.
