目的：微创人工耳蜗植入术是一种从乳突面向耳蜗底弯方向钻取耳蜗管的手术方法。假设适当的钻孔策略的选择对可实现的目标精度具有显著影响。因此，提出了一种方法来分析的钻孔过程和钻孔工具的贡献，从其他误差源隔离的目标错误。MethodsThe实验设置，以评估钻孔精度包括一个钻头手机连接到一个线性滑块，以及一个高精度的坐标测量机（CMM）。根据微创耳蜗入路的具体要求，推导出三种以不同钻削工具为主要特征的钻孔策略。通过钻入含有充气腔以模拟乳突细胞的合成颞骨替代物来评估这些策略。从所需的钻头轨迹的偏差确定使用CMM.ResultsUsing的实验设置的测量值的基础上，共钻了144孔的精度评价。钻孔过程导致的误差取决于工具的特定几何形状以及钻头接触骨表面的角度。此外，有一个钻头偏转的风险，由于合成的乳突cells.ConclusionsA单槽枪钻结合相同直径的导钻提供了最好的结果，模拟微创人工耳蜗植入术，基于一种实验方法，可用于测试进一步的钻孔过程的改进。
PurposeMinimally invasive cochlear implantation is a surgical technique which requires drilling a canal from the mastoid surface toward the basal turn of the cochlea. The choice of an appropriate drilling strategy is hypothesized to have significant influence on the achievable targeting accuracy. Therefore, a method is presented to analyze the contribution of the drilling process and drilling tool to the targeting error isolated from other error sources.MethodsThe experimental setup to evaluate the borehole accuracy comprises a drill handpiece attached to a linear slide as well as a highly accurate coordinate measuring machine (CMM). Based on the specific requirements of the minimally invasive cochlear access, three drilling strategies, mainly characterized by different drill tools, are derived. The strategies are evaluated by drilling into synthetic temporal bone substitutes containing air-filled cavities to simulate mastoid cells. Deviations from the desired drill trajectories are determined based on measurements using the CMM.ResultsUsing the experimental setup, a total of 144 holes were drilled for accuracy evaluation. Errors resulting from the drilling process depend on the specific geometry of the tool as well as the angle at which the drill contacts the bone surface. Furthermore, there is a risk of the drill bit deflecting due to synthetic mastoid cells.ConclusionsA single-flute gun drill combined with a pilot drill of the same diameter provided the best results for simulated minimally invasive cochlear implantation, based on an experimental method that may be used for testing further drilling process improvements.
