BACKGROUND: A virtual reality neurosurgery simulator with haptic feedback may help in the training and assessment of technical skills requiring the use of tactile and visual cues. OBJECTIVE: To develop a simulator for craniotomy-based procedures with haptic and graphics feedback for implementation by universities and hospitals in the neurosurgery training curriculum. METHODS: NeuroTouch was developed by a team of more than 50 experts from the National Research Council Canada in collaboration with surgeons from more than 20 teaching hospitals across Canada. Its main components are a stereovision system, bimanual haptic tool manipulators, and a high-end computer. The simulation software engine runs 3 processes for computing graphics, haptics, and mechanics. Training tasks were built from magnetic resonance imaging scans of patients with brain tumors. RESULTS: Two training tasks were implemented for practicing skills with 3 different surgical tools. In the tumor-debulking task, the objective is complete tumor removal without removing normal tissue, using the regular surgical aspirator (suction) and the ultrasonic aspirator. The objective of the tumor cauterization task is to remove a vascularized tumor with an aspirator while controlling blood loss using bipolar electrocautery. CONCLUSION: NeuroTouch prototypes have been set up in 7 teaching hospitals across Canada, to be used for beta testing and validation and evaluated for integration in a neurosurgery training curriculum.
背景:具有触觉反馈的虚拟现实神经外科模拟器可能有助于培训和评估需要使用触觉和视觉线索的技术技能。
目的:为基于颅骨切开术的手术开发具有触觉和图形反馈的模拟器,供大学和医院在神经外科培训课程中实施。
方法:NeuroTouch 由来自加拿大国家研究委员会的 50 多名专家团队与来自加拿大 20 多所教学医院的外科医生合作开发。它的主要组件是立体视觉系统、双手触觉工具操纵器和高端计算机。模拟软件引擎运行 3 个用于计算图形、触觉和力学的进程。培训任务是根据患有脑瘤的患者的磁共振成像扫描构建的。
结果:实施了 2 个训练任务,使用 3 种不同的手术工具来练习技能。在肿瘤切除任务中,目标是在不切除正常组织的情况下完全切除肿瘤,使用常规手术吸引器(抽吸)和超声吸引器。肿瘤烧灼任务的目标是使用吸引器去除血管化肿瘤,同时使用双极电灼术控制出血。
结论:NeuroTouch 原型已在加拿大的 7 所教学医院中建立,用于进行测试和验证,并评估其在神经外科培训课程中的整合。
