Reverse Engineering of Kerrison Rongeurs and Medical Instruments

This project involved the reconstruction and engineering modeling of Kerrison rongeurs and a range of mechanical medical instruments. The work included analysis of component geometry, functional relationships, moving interfaces, working elements, handles, connecting parts, and assembly structure. The reconstruction process focused on preserving the functional intent of the instruments while creating editable and technically consistent CAD geometry. The project included: • Reconstruction of individual components • Assembly relationship analysis • Functional interface verification • Modeling of working and supporting elements • Geometry consistency checks • Preparation of STEP models • Organization of multiple product variants • Manufacturing-oriented model structure The project required careful attention to small mechanical features and interaction between components. The resulting models were prepared for further engineering review, manufacturing documentation, product modification, and controlled production use.
