LASER ORTHOSCOPE FOR REVISION ARTHROPLASTY

THE LASER ORTHOSCOPE IS DESIGNED FOR THE AUTOMATED PRECISIONREMOVAL OF RESIDUAL POLYMETHYLMETHACRYLATE (PMMA) BONE CEMENT ENCOUNTERED DURING REVISION ARTHROPLASTY. THE EXISTING TECHNOLOGY FOR THE REMOVAL OF PMMA CONSISTS OF MANUAL TOOLS AND HIGH-SPEED DRILLS THAT ARE ASSOCIATED WITH COMPLEX, PROTRACTED SURGICAL OPERATIONS AND HIGH PATIENT MORBIDITY. THE PURPOSE OF THIS PROJECT IS TO DEVELOP THE LASER ORTHOSCOPE AND TO DEMONSTRATE ITS EFFICACY FOR THE REMOVAL OF PMMA IN A REALISTIC MODEL. THIS SYSTEM IS DESIGNED TO BECOST EFFECTIVE, EASY TO OPERATE, AND EFFICIENT. BY INCORPORATING AN INTRAOPERATIVE COMPUTER-AUTOMATED LASER GUIDANCE SYSTEM, STATE-OF-THE-ART VIDEO IMAGING, AND A CLOSED SURGICAL FIELD COOLED BY NITROGEN GAS, THE LASER ORTHOSCOPE SYSTEM WILL OFFER THE RECONSTRUCTIVE ORTHOPEDIC SURGEON THE NEXT GENERATION OF REVISION ARTHROPLASTY EQUIPMENT.
