During cochlear implantation, hearing preservation is a concern. Minimizing disturbances to the cochlea and protection of the underlying endosteal membrane during the formation of a cochleostomy are considered important factors. The robotic micro-drill system tested in this article is the first example of an autonomous surgical drill successfully producing a cochleostomy, which keeps the underlying endosteal membrane intact. This study compares induced disturbances within the cochlea during formation of cochleostomy using the robotic micro-drill with that of conventional manual drilling. The disturbance of the endosteal membrane is measured using a Microscope Scanning Vibrometer at a third window, produced in the cochlea. Results show that the highest velocity amplitude measured was associated with manual drilling technique. The robotic micro-drill technique produced only about 1% of the peak velocity amplitude seen in manual drilling and exhibited much more uniform behaviour, while keeping the underlying membrane intact. The technique applied when using the robotic drill could be a major step in reducing the trauma to the cochlea, by reducing disturbance levels.
在人工耳蜗植入过程中，听力保留是一个值得关注的问题。在形成耳蜗造口术时，尽量减少对耳蜗的干扰并保护其下方的骨内膜被认为是重要因素。本文测试的机器人微型钻孔系统是成功制造出耳蜗造口术且能保持其下方骨内膜完整的自主手术钻孔设备的首个实例。本研究比较了使用机器人微型钻孔与传统手动钻孔形成耳蜗造口术时耳蜗内产生的干扰情况。使用显微镜扫描振动计在耳蜗产生的第三个窗口测量骨内膜的干扰情况。结果表明，测得的最高速度幅值与手动钻孔技术相关。机器人微型钻孔技术产生的峰值速度幅值仅约为手动钻孔的1%，并且表现出更均匀的特性，同时保持下方膜的完整。使用机器人钻孔时应用的技术通过降低干扰水平，可能是减少耳蜗创伤的重要一步。
