Navigated control (NC) is an advanced image-guided navigation system that provides an additional control function to enhance patient safety. It automatically stops the surgical instrument if it comes close to critical anatomical structures that need to be protected during surgery. The purpose of this study was to explore the human performance consequences of computer-based navigated control assistance.
Seven experienced surgeons conducted a simulated mastoidectomy manually and with support of the NC system. The impact on surgical performance, workload and situation awareness was analysed.
NC support led to a better quality of surgical outcome and a lower level of physiological effort during surgery. Cost effects were reflected in reduced time efficiency and an increased subjectively experienced workload.
The results demonstrate the potential of NC support in terms of lower workload and enhanced patient safety. Cost effects might be reduced by remodelling the control function.
导航控制（NC）是一种先进的图像引导导航系统，它提供了额外的控制功能以提高患者安全性。如果手术器械接近手术过程中需要保护的关键解剖结构，它会自动停止。本研究的目的是探讨基于计算机的导航控制辅助对人体操作的影响。
七名经验丰富的外科医生分别在手动操作和NC系统支持下进行了模拟乳突切除术。分析了其对手术操作、工作量和态势感知的影响。
NC支持带来了更好的手术效果质量，且手术期间生理应激水平更低。成本影响体现在时间效率降低和主观感受的工作量增加上。
结果表明NC支持在降低工作量和提高患者安全性方面具有潜力。通过重新设计控制功能可能会降低成本影响。
