Application of non-linear access paths for MUKNO

本项目的目的是为应用耳基非线性微创通路创造前提条件。一个重要的方面是开发一个钻，可以应用非线性路径在头骨。目前，用于外科手术的现有钻头系统只建议采用线性钻头路径，因为到目前为止，即使使用灵活的驱动概念，也不可能在非线性部分后面定位和固定钻头。因此，该项目的一个目标是开发一种可以在钻道的任何地方固定自己的钻头胶囊，并具有进给和对准机制。为了允许模拟规划数据的路径钻孔，必须初始定位钻孔胶囊。此外，定位单元必须适应产生非线性钻孔路径的任务所产生的要求，例如，钻孔胶囊的定位和对准。为了确保使用新开发的钻孔胶囊进行的钻孔过程，并进一步降低损坏敏感结构的风险，将对测量概念进行检查。因此，对骨密度、温度和到下一个敏感结构的距离等参数进行分析，以确定它们与过程安全性的相关性，以及捕获这些参数的方法，这些参数可以集成到钻囊中。

The objective of this project is to create the preconditions for applying non-linear minimally invasive access paths at the otobasis. An important aspect is to develop a drill which can apply non-linear paths in the scull. Existing drill systems for surgery nowadays only suggest linear drill paths as it is not possible to position and to fix the drills behind non-linear sections so far, even when using flexible drive concepts. One objective of this project is therefore to develop a drill capsule that can anchor itself anywhere in the drill canal and which has a feed and alignment mechanism. To allow the drilling of the path analog the planning data it is essential to initially position the drill capsule. Furthermore, the positioning unit has to be adapted to demands resulting from the task to generate non-linear drill paths, e.g. the positioning and alignment of the drill capsule.To secure the drill process carried out with the newly developed drill capsule and to reduce the risk of damaging sensitive structures further, measurement concepts will be examined. Therefore, parameters like bone density, temperature and the distance to the next sensitive structure are analyzed regarding their relevance for the safety of the process and regarding methods to capture these parameters which can be integrated into the drill capsule.
