CELTS
A Computer Enhanced Laparoscopic Training System Metrics are widely employed in virtual environments and provide a yardstick for performance measurement. The current method of defining metrics for medical simulation remains more an art than a science. CELTS offers a practical scientific approach to defining metrics, specifically aimed at computer-assisted laparoscopic skills training. The metrics are defined in an explicit way based on the relevant skills that a laparoscopic surgeon should master. The system utilizes a five degree-of-freedom device and a software platform capable of 1) tracking the motion of two laparoscopic instruments 2) real time information processing and feedback provision. A validation study was performed. The results show that our metrics and scoring system represent a technically sound approach that can be easily incorporated in a computerized trainer for any task, enabling a standardized performance assessment method. CELTS is the foundation for a standardized global scoring system usable across different laparoscopic trainers and tasks. |
