The goal of this study was to enhance robotic surgical training via real-time augmented visual feedback. Thirty novices (medical students) were divided into 5 feedback groups (speed, relative phase, grip force, video, and control) and trained during 1 session in 3 inanimate surgical tasks with the da Vinci Surgical System. Task completion time, distance traveled, speed, curvature, relative phase, and grip force were measured immediately before and after training and during a retention test 2 weeks after training. All performance measures except relative phase improved after training and were retained after 2 weeks. Feedback-specific effects showed that the speed group was faster than other groups after training, and the grip force group applied less grip force. This study showed that the real-time augmented feedback during training can enhance the surgical performance and can potentially be beneficial for both training and surgery.
本研究的目的是通过实时增强视觉反馈来加强机器人手术训练。30名新手（医学生）被分为5个反馈组（速度、相对相位、握力、视频和对照组），并使用达芬奇手术系统在1次训练中对3项无生命的手术任务进行训练。在训练前后以及训练后2周的留存测试期间，测量任务完成时间、移动距离、速度、曲率、相对相位和握力。除相对相位外，所有性能指标在训练后均有所改善，并在2周后得以保持。特定反馈效应表明，训练后速度组比其他组更快，握力组施加的握力更小。本研究表明，训练期间的实时增强反馈可提高手术操作表现，并且可能对训练和手术都有益。
