Robotic Surgical Educational Training

Nelson-Siu Collaboration: Portable Camera Aided Simulator (PortCAS) for Minimally Invasive Surgical Training

We present a portable and inexpensive laparoscopic simulator called PortCAS (Portable Camera Aided Surgical Simulator), which allows training to be performed via a web-based interface and blend in the advantages of learning management systems as well. A computer-vision based approach (a binocular vision system using two webcams) is used to detect the position of surgical graspers within a workspace that folds away and stows inside a briefcase. All tool movements are streamed to a server, and trainees perceive their motions in real time in a browser-based virtual environment that simulates the surgical task. Presently, three different virtual tasks have been designed to help trainees learn specific laparoscopic skills.
