The medical industry currently offers a wide range of engineered products including a quick connect for surgical drills. A drawback associated with the quick connect is that the coupler does not offer a rigid connection between the drill and the cutting tool. This results in wobble of the cutting tool felt by the surgeon. The team was tasked with fixing the perceived problem of vibrations affecting the quality of the reamed Acetabular Socket. The project began by benchmarking the quick connects currently offered by Stryker and their competitors. After completion of benchmarking, the team moved into the design and simulation phase. Several designs were considered and 3D printed before moving into the machining phase. To simplify machining and reduce cost, the design was simplified, with all non-critical features removed. Next, the team tested the machined prototype for wobble reduction using a high speed camera and tested the ability to transmit torque by subjecting it to a load. The tests data was analyzed and the prototype design was updated based on the knowledge obtained through testing. Through multiple redesigns, use of finite element analysis (FEA), and testing of a prototype to validate performance the Total Indicated Runout (TIR) and wobble were reduced.
