Abstract: A modular, ergonomic training system designed to teach and evaluate laparoscopic surgical skills through a collapsible frame featuring adjustable trocar ports that simulate real-world surgical scenarios for both right- and left-handed users. It includes a pegboard for attaching various training modules to practice tasks like object manipulation, precision cutting, and suture tying. The system integrates augmented reality (AR) and artificial intelligence (AI) for real-time, step-by-step guidance and performance analysis. AR overlays on a live video feed from a tablet mounted on the frame offer visual instructions, while AI algorithms evaluate metrics such as precision and technique, providing personalized feedback and automated skill assessment. Additional features include a rechargeable light source that mimics clinical lighting and reflective surfaces for enhanced performance monitoring.

Abstract: Disclosed herein is a safety trench box for use in protecting workmen from cave-ins while operating within an excavated area. The device includes a barrier which surrounds the work area having a depth substantially that of the trench and an opening along one wall of the barrier that allows work to be sequentially fed therethrough. The safety device includes a pair of runners upon which the device is carried so that advancing the safety device can be easily accomplished.
