Abstract
Hip surgery is among the most common inpatient surgeries. In order to introduce and anchor the implant in the femur, an implant fitting cavity is created, mostly manually, utilizing a set of differently sized rasps, which can be time consuming. A simple tool that creates cavities in final size fast and reproducible in an easy to handle process without inflicting high forces to the patient would be desirable. Due to the cavity’s shape, rotatory methods (drilling) are not applicable. The Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) is working on tools designated for the creation of non-round holes in various substrates, possibly also suitable for the creation of cavities in bone. In the development of such a tool a biomimetic approach was chosen, which is presented together with first evaluation tests in the following sections.
