Cerebral Aneurysm Clipping Training Simulator using Virtual Reality and Haptics

描述(由申请人提供)：IMMERSIVETOUCH(R)虚拟现实-触觉神经外科模拟器：由首席研究员Pat Banerjee博士(ImmersiveTouch，(R)Inc.(伊利诺伊州韦斯特蒙特))创立的开颅手术和动脉瘤夹闭手术是一家小型企业，开发完全沉浸式、视觉触觉的虚拟现实软件，设计成一个硬件工作站，用于外科住院医师的培训。该公司的模拟器为住院医生提供重复的、并置的虚拟现实-触觉练习，以加速学习和传授手术室技能，而不会给患者带来风险。脑(颅内)动脉瘤破裂是一种常见的疾病，死亡率和发病率都很高。动脉瘤的外科治疗是具有挑战性的，需要很长的训练期。这样的培训是强制性的。ACGME神经外科住院医师审查委员会规定，住院病例负荷“应包括创伤、肿瘤、动脉瘤和血管畸形的开颅手术”。由于ImmersiveTouch模拟器已经被用于脑室造口的教育验证，我们建议在这里验证它在大脑中动脉(MCA)分叉处夹闭动脉瘤的有效性。在传统的显微神经外科手术中，通过开颅手术和动脉瘤夹闭术，住院医师培训的压力越来越大。这是由于住院工作时间的减少和动脉瘤夹闭术中病例负荷的减少，超过一半的简单动脉瘤采用血管内治疗方法。现在有必要对神经外科医生进行更多的培训，使他们能够胜任动脉瘤夹闭手术。在伊利诺伊大学芝加哥分校和芝加哥大学是一个项目合作伙伴，超过90%的需要夹闭的动脉瘤形成于来自颈内动脉的动脉，包括位于M1-M2分支的大脑中动脉？这种手术是通过翼点开颅手术，然后沿着侧裂(大脑中动脉及其分支和动脉瘤所在的地方)进行解剖。该模拟将教授翼点开颅手术、硬脑膜开口、沿预先解剖的侧裂导航、动脉瘤夹闭和血流测试，以确保充分夹闭和开放邻近血管。阶段I将患者CT体素数据转换为大脑中动脉分叉部动脉瘤和侧裂等的3D虚拟现实-触觉模型。我们还在3D中建模了动脉瘤夹层。第二阶段侧重于为开颅手术、硬脑膜切开和动脉瘤夹闭的模拟器编程，并进行验证。 与公共健康相关：ImmersiveTouch公司开发创新的增强虚拟现实系统，用于培训神经外科住院医生。该伙伴关系与伊利诺伊大学芝加哥分校和芝加哥大学合作，提议进行研究，以克服目前的一些技术障碍。如果成功，在STTR第一和第二阶段之后，ImmersiveTouch-Sensimmer神经外科训练器将克服导致评估开颅手术和脑动脉瘤夹闭以及其他衍生神经外科手术的挑战，

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,
