Early design concepts and early production units of this multi-planer positioning system were built using metal fabrications – fast, low cost from a tooling and lead time stand point. Ultimately not cost effective for long term production.
A change eas needed to ensure future profitability and ease of assembly and use by the physician. NT staff went to work with an extensive redesign which incorporated state of the art rigid materials, slip lock connections, ease of use and adjustment.
Engineering:
Develop rigid, precision, adjustable bone fixture device
Challenge:
