Micropick fenestration of the stapes footplate, a difficult step in stapedotomy, was selected for trials evaluating the potential for robotic assistance (RA) to improve clinical measures of surgical performance.
In a surgical model of stapedotomy, we measured accuracy of fenestration to a desired point location and force applied to the stapes footplate. Performance variables were measured for 3 experienced and 3 less-experienced surgeons.
RA significantly reduced the maximum force applied to the stapes footplate. For fenestration targeting, RA significantly improved accuracy for less-experienced surgeons and significantly worsened targeting for more-experienced surgeons.
RA significantly improves performance for micropick fenestration in a surgical model of stapedotomy. For certain tasks, RA differentially affects performance for users of different experience levels.
These are the first results showing quantitative improvements in performance during simulated ear surgery using RA and differential effects of RA on performance for users of different experience levels.
镫骨足板微开窗是镫骨手术中的一个难点步骤，本研究选择该步骤来评估机器人辅助（RA）改善手术操作临床指标的潜力。
在镫骨手术的手术模型中，我们测量了开窗到指定点位置的准确性以及施加在镫骨足板上的力。对3名经验丰富的外科医生和3名经验较少的外科医生的手术操作变量进行了测量。
机器人辅助显著降低了施加在镫骨足板上的最大力。对于开窗定位，机器人辅助显著提高了经验较少的外科医生的准确性，而显著降低了经验丰富的外科医生的定位准确性。
在镫骨手术的手术模型中，机器人辅助显著提高了微开窗的操作性能。对于某些任务，机器人辅助对不同经验水平的使用者的操作性能有不同影响。
这些是首次显示在模拟耳部手术中使用机器人辅助后操作性能有定量改善以及机器人辅助对不同经验水平使用者的操作性能有不同影响的结果。
