Design of a Force Measurement Table, providing objective force feedback during arthroscopic training on cadaver specimen

To improve arthroscopic skills, orthopaedic residents train on medical simulators and cadaveric training courses. Some medical simulators provide feedback while cadaveric specimen offer the most realistic training environments. Providing objective feedback while training on cadaveric specimen will be an major improvement to the cadaveric training courses. The goal of this project is to develop a system that allows for objective force feedback during arthroscopic skills training on cadaveric specimen. To accomplish this we follow three basic steps: an analysis of the procedure is made, a theoretical model is developed, and from multiple concepts a 6DOF force sensor method is chosen. We developed a 6DOF force platform Force Measurement Table (FMT), which measures forces and torques in the range of 0-750N, with an accuracy of ±0.32N. The FMT was calibrated, and has proven to be able to distinguish between two statically provided independent forces. A pilot study with two intermediates showed a significant difference between the average forces exerted by the arthroscope (2.4 ±1.2N) and by the instrument with arthroscope (4.5 ±2.4N). This difference in force deviations indicates that the highest loads are mostly exerted by the probing instrument. The technology of the FMT shows high potential for the use of force measurements during cadaveric training courses. For exact dynamical measurements, an accurate tracking system can be to be added to the FMT.
