项目摘要

DESCRIPTION (provided by applicant): IMMERSIVETOUCH(R) VIRTUAL REALITY-HAPTIC NEUROSURGERY SIMULATOR: CRANIOTOMY AND ANEURYSM CLIPPING Founded by principal investigator Dr. Pat Banerjee, ImmersiveTouch,(R) Inc. (Westmont, Illinois) is a small business that develops fully immersive, visio-haptic virtual reality software engineered into a hardware workstation for the training of surgical residents. The Company's simulator provides residents with repeated, collocated virtual reality-haptic practice needed to accelerate learning and impart skills for the operating room without risk to patients. Brain (intracranial) aneurysm rupture is common and is associated with high mortality and morbidity. The surgical treatment of aneurysms is challenging, requiring a long training period. Such training is mandated. The ACGME Residency Review Committee for Neurological Surgery stipulates that resident case load "should include craniotomies for trauma, neoplasms, aneurysms, and vascular malformations". Since the ImmersiveTouch simulator has already been educationally validated for ventriculostomy, we propose here to validate it for aneurysm clipping at the MCA (middle cerebral artery) bifurcation. There is increasing pressure on resident training in classic microneurosurgery by open craniotomy and aneurysm clipping. This is due to a reduction in resident work hours and a decreasing case load in aneurysm clipping, with more than half of simpler aneurysms treated with endovascular means. Additional means of training neurosurgeons to become competent at aneurysm clipping is now necessary. At University of Illinois at Chicago, which is a project partner along with University of Chicago, more than 90 percent of aneurysms requiring clipping form on arteries that arise from the internal carotid artery, including the MCA at the M1-M2 branch? This surgery is performed through a pterional craniotomy followed by dissection along the Sylvian fissure (where the MCA, its branches, and the aneurysm are located). The simulation will teach a pterional craniotomy, dural opening, navigation along a pre-dissected Sylvian fissure, clipping of the aneurysm and blood flow testing to ensure adequate clipping and patency of the adjacent vessels. Phase I converted patient CT voxel data into a 3D virtual reality-haptic model of an MCA bifurcation aneurysm and the Sylvian fissure, etc. We also modeled aneurysm clips in 3D. Phase II focuses on programming the simulator for craniotomy, dural opening, and aneurysm clipping, and on validation. PUBLIC HEALTH RELEVANCE: ImmersiveTouch Inc. develops innovative augmented virtual reality systems for training of neurosurgical residents. In collaboration with the University of Illinois at Chicago and University of Chicago, the Partnership proposes to conduct research to overcome some of the current technical barriers. If successful, following STTR Phases I and II, the ImmersiveTouch-Sensimmer Neurosurgical Trainer will overcome challenges leading to evaluation of craniotomy and cerebral aneurysm clipping and other derivative neurosurgical procedures,

描述（由申请人提供）：沉浸式（R）虚拟现实感受神经外科手术模拟器：由主要研究人员Pat Banerjee博士（Immersivetouch，Inc。（R）Inc。（Westmont，Illinois）建立的颅骨切开术和动脉瘤剪切，是为居民提供了全面的，vive的现实工具，该工具构成了一项艰难的现实工程，该工具构成了一项艰难的工程，该企业是一项全面的小型企业。该公司的模拟器为居民提供了重复的，相处的虚拟现实式示意练习，以加速学习室的学习和赋予患者风险的技能。脑（颅内）动脉瘤破裂很常见，并且与高死亡率和发病率有关。动脉瘤的手术治疗具有挑战性，需要长时间的训练期。要求这样的培训。 ACGME神经手术居住审查委员会规定，居民案件负荷“应包括用于创伤，肿瘤，动脉瘤和血管畸形的颅骨群”。由于沉浸式模拟器已经在心室造口术进行了教育验证，因此我们在这里提议在MCA（大脑中部动脉）分叉进行验证以进行动脉瘤剪切。通过开颅切开术和动脉瘤剪切，对经典微管外科手术的常驻训练压力越来越大。这是由于居民工作时间的减少以及动脉瘤剪切中的病例负荷减少，其中一半以上的简单动脉瘤用血管内平均值处理。现在需要训练神经外科医生在动脉瘤剪切上胜任的其他手段。在伊利诺伊大学的芝加哥大学，这是与芝加哥大学一起的项目合作伙伴，超过90％的动脉瘤需要在颈内动脉引起的动脉上进行剪裁，包括M1-M2分支的MCA？该手术是通过翼型颅骨切开术进行的，然后沿Sylvian裂缝（MCA，其分支和动脉瘤的位置）进行解剖。该模拟将教导颅骨切开术，硬脑膜开口，沿预先删除的Sylvian裂缝，动脉瘤和血流测试的剪断，以确保相邻船只的足够剪切和通畅。第一阶段将患者的CT Voxel数据转换为MCA分叉动脉瘤和Sylvian Fissure等的3D虚拟现实热模型。我们还以3D为模型。第二阶段的重点是编程颅骨切开术，硬脑膜开口和动脉瘤剪切以及验证的模拟器。公共卫生相关性：Immersivetouch Inc.开发了创新的增强虚拟现实系统，用于培训神经外科居民。与伊利诺伊大学芝加哥大学和芝加哥大学合作，该合作伙伴关系提议进行研究以克服一些当前的技术障碍。如果成功，遵循STTR阶段I和II，沉浸式感应器神经外科培训师将克服挑战，从而评估颅骨切开术和脑动脉瘤的剪切和其他衍生神经外科手术，，以及其他衍生神经外科手术程序，
