Abstract
The Nuss procedure is a minimally invasive procedure for the correction of pectus excavatum - a chest wall deformity which results in the placement of a metal bar inside the chest cavity. The bar is removed after approximately two years. Surgeons have been reporting that the currently available tools for the extraction of the bar do not provide the most optimal functionality. Previously, we had proposed a novel design of the tool which showed deficiencies when experimentally tested. With the aid of CAD and finite element analysis, modifications to the original design were adopted to drastically increase the factor of safety. The improved tool is prototyped and will be clinically evaluated by the surgeon.
