介绍了一种基于计算机的环形撕囊仿真系统--虚拟超声乳化训练器。感兴趣的居民和外科医生可以使用该系统导航撕囊手术并练习他们的技能。性能数据在每次实践后都有客观的性能评估指标。该系统作出了一些重要贡献，一个质量弹簧模型为基础的各向异性网格被用来模拟可变形的胶囊模型沿着与光滑的曲线撕囊路径。为了精确导航，幻影触觉设备被用来跟踪位置以及提供无障碍的触觉反馈。解决了高密度网格更新频率和高触觉反馈更新频率之间的冲突要求。提出并讨论了一组眼科住院医师和主治外科医生的有前途的评价结果。
A computer based curvilinear capsulorrhexis simulation system known as Virtual Phaco Trainer is presented. Interested residents and surgeons can use this system to navigate through the capsulorrhexis procedures and practice their skills. Performance data is presented after each practice with built in objective performance evaluation metrics. The system makes a number of important contributions A mass-spring model based anisotropic mesh is used to simulate a deformable capsule model along with a smooth curvilinear capsulorrhexis path. To navigate precisely, a phantom haptic device is used to track positions as well as to provide snag-free haptic feedback. Solutions to conflicting requirements between a high density mesh update frequency and a high haptic feedback update frequency are addressed. Promising evaluation results from a group of ophthalmology residents and attending surgeons are presented and discussed.
