A minimally-invasive surgical (MIS) approach to cochlear implantation, if safe, practical, simple in surgical handling, and also affordable has the potential to replace the conventional surgical approaches. Our MIS approach uses patient-specific drilling templates (positioning jigs). While the most popular MIS approaches use robots, the robotic aspect is literally put aside, because our high-precision parallel kinematics is only used to individualize a positioning jig. This jig can then be mounted onto a bone-anchored mini-stereotactic frame at the patient's skull and used to create a drill-hole through the temporal bone to the patient's cochlea. We present the first clinical experience where we use sham drill bits of different diameters instead of drilling into the bone in order to demonstrate the feasibility and accuracy.
一种用于人工耳蜗植入的微创外科（MIS）方法，如果安全、实用、手术操作简单且成本可承受，就有可能取代传统的外科手术方法。我们的MIS方法使用针对患者的钻孔模板（定位夹具）。虽然最流行的MIS方法使用机器人，但机器人部分实际上被搁置一旁，因为我们的高精度并联运动学仅用于使定位夹具个性化。然后可以将该夹具安装在患者颅骨上的骨锚定微型立体定向框架上，并用于在颞骨上钻出一个通向患者耳蜗的钻孔。我们展示了首次临床经验，即我们使用不同直径的假钻头而不是钻入骨头，以证明其可行性和准确性。
