Abstract
In the past few years a novel area of research and development - Computer Assisted Orthopaedic Surgery (CAOS) - has been established. Its primary goal is to provide a direct link between preoperative planning and intraoperative surgical action. Key elements to this link are surgical trackers allowing precision image-interactive surgical procedures. Trackers can be either freehand based on optoelectronic or electro-magnetic concepts or robots operating in semi-constraint (surgeon-driven) or autonomous modes. Associated surgical modules have emerged from the laboratory and are being clinically used in various orthopaedic subspecialties on a routine basis, such as joint replacements, spinal and trauma interventions, etc. In combination with advanced intraoperative imaging devices, fast and reliable percutaneous registration and referencing techniques as well as virtual und augmented realities the "transparent patient" may soon become reality. Part of such a scenario the development of new surgical devices, i.e. instruments and implants should be seen. In this field a rather conservative attitude of orthopaedic device manufacturers and surgeons can be identified. This is in contrast to related pure technological areas, where a quantum leap of innovation has been observed in the past decades. In particular there have been groundbreaking developments in fields such as mechatronics, micro-sensor and actuator technology, microelectronics, systems technology, etc. In addition, material science research has brought forward revolutionary options for technology developers. A vast number of corresponding laboratory prototypes have emerged into successful engineering products in large scale markets, such as consumer electronics, automotive industry, etc. Transfer of these engineering technologies into the medical arena may provide novel opportunities for medical applications. In the future they hold potential to further optimize the treatment loop, i.e. the way we diagnose, plan, simulate, execute, document and evaluate a surgical procedure. In this presentation an overview is given of the state of the art in research and development on smart surgical device technology, i.e. instruments and implant involving advanced sensor and actuator technology. Special focus is on their use in orthopaedic interventions.
Bio
Lutz-Peter Nolte is professor for Surgical Technology and Biomechanics at the University of Bern, Switzerland. He received the M.Sc. and Ph.D. degrees from the Ruhr-University Bochum, Germany in 1980 and 1983. During 1984-87 he headed the Nonlinear Shell Research Group at the Institute of Mechanics of the Ruhr-University Bochum, working in the field of elastic and elasto-plastic deformations of thin-walled engineering structures. From 1987 to 1990 he established the Orthopaedic Research Group at the Ruhr-University Bochum focussing his work on spinal biomechanics. In 1990 Dr. Nolte joined the Bioengineering Center at Wayne State University in Detroit, MI, USA as an Associate Professor of Mechanical Engineering. In collaboration with the Department of Neurosurgery he extended the scope of his research to computer aided surgery. In 1993 he took over the Orthopaedic Biomechanics Division at the MEM Institute for Biomechanics in Bern. Since 2001 Dr. Nolte is co-director of the Swiss National Center for Competence in Research Computer Aided and Image Guided Medical Interventions (http://co-me/) located at the ETHZ. In 2002 he became the co-director of the MEM Research Center for Orthopaedic Surgery and the director of the Institute for Surgical Technology and Biomechanics at the Medical Faculty of the University of Bern. Since 2007 he is the director of the newly founded ARTORG Center for Biomedical Engineering Research at the same institution (www.artorg.unibe.ch).
