结论：目前用于评估手术技能的大多数方法都是相当主观的，或者不适合显微神经外科手术。客观和定量的显微神经外科技能评估系统，能够准确的测量是必要的显微neurosurgery.METHODS的进一步发展：红外光学运动跟踪标记，惯性测量单元，和应变片被安装在镊子测量许多参数相关的仪器操作。然后，我们记录了23名神经外科医生的活动。评价了在0.7 mm人工血管吻合术中进行的三次缝合的任务完成时间、工具路径和针夹持力。活动的视频进行了评估，由三个盲专家surgeon.RESULTS：最近做了许多搭桥手术的外科医生表现出更好的技能。这些熟练的外科医生在更短的时间内完成吻合，使用更短的工具路径，并且在拔针时使用更小的力。结论：这些结果显示了该系统对显微外科技能评估的潜在贡献。手术任务的定量和详细分析有助于外科医生更好地了解所需技能的关键特征。
OBJECTIVES: Most methods currently used to assess surgical skill are rather subjective or not adequate for microneurosurgery. Objective and quantitative microneurosurgical skill assessment systems that are capable of accurate measurements are necessary for the further development of microneurosurgery.METHODS: Infrared optical motion tracking markers, an inertial measurement unit, and strain gauges were mounted on tweezers to measure many parameters related to instrument manipulation. We then recorded the activity of 23 neurosurgeons. The task completion time, tool path, and needle-gripping force were evaluated for three stitches made in an anastomosis of 0.7-mmartificial blood vessels. Videos of the activity were evaluated by three blinded expert surgeons.RESULTS: Surgeons who had recently done many bypass procedures demonstrated better skills. These skilled surgeons performed the anastomosis with in a shorter time, with a shorter tool path, and with a lesser force when extracting the needle.CONCLUSIONS: These results show the potential contribution of the system to microsurgical skill assessment. Quantitative and detailed analysis of surgical tasks helps surgeons better understand the key features of the required skills.
