One of the most common procedures in neurosurgery is the trepanation of the skull. In this paper, a synergistically controlled handheld tool for trepanation is introduced. This instrument is envisioned to reduce problems of dural tears and wide cutting gaps by combining a soft tissue preserving saw with an automatic regulation of the cutting depth. Since usability and safety of the semi-automatic handheld device are of utmost importance, the complex interaction between the user and the system has been analyzed extensively. Based on prospective usability evaluation the user interaction design and the corresponding user-interface were developed. The compliance with the relevant factors effectiveness, efficiency, error tolerance, learnability and user satisfaction was measured in user-centered experiments to evaluate the usability of the semiautomatic trepanation system. The results confirm the user interaction design of the semiautomatic trepanation system and the corresponding safety strategy. The system seems to integrate itself smoothly into the existing workflow and keeps the surgeon aware of the process.
颅骨环锯术是神经外科最常见的手术之一。本文介绍了一种用于颅骨环锯术的协同控制手持工具。该器械旨在通过将软组织保护锯与切割深度自动调节相结合，减少硬脑膜撕裂和宽切割间隙的问题。由于半自动手持设备的可用性和安全性至关重要，因此对用户与系统之间的复杂交互进行了广泛分析。基于前瞻性可用性评估，开发了用户交互设计和相应的用户界面。在以用户为中心的实验中测量了与有效性、效率、容错性、可学习性和用户满意度等相关因素的符合程度，以评估半自动环锯系统的可用性。结果证实了半自动环锯系统的用户交互设计和相应的安全策略。该系统似乎能顺利融入现有的工作流程，并让外科医生随时了解手术进程。
