Abstract

Bone drilling is a surgical action required for bone fixation using plates. The holes are currently drilled using a large, conventional drill. This causes problems when limited space is available, de to the size of the drill. For that reason a new, small Compact Drilling System is proposed. In earlier research a compact self-feeding mechanism was introduced, various implementations of that mechanism are presented here. A module, to be used in combination with a conventional drill, is used as a bridging step towards a fully redesigned device. An example locking mechanism is designed, used to lock the module in place during the drilling. FEM techniques are used to validate the design, and adapt it where necessary.
