The purpose of the development of Virtual Airway Skill Trainer (VAST)  is to provide a safe training environment for clinicians to learn the airway management techniques without risk to actual patients, standardize the process of skill training and allow automatic quantification of performance. The virtual simulator, equipped with visual as well as haptic interfaces provides an immersive environment that enables the users to touch, feel and manipulate virtual anatomies. We use Oculus Rift for immersive visual display to simulate operating room experience. Furthermore, to determine the critical procedural steps in airway procedure and metrics for assessing users’ performance such as operation accuracy and tasks completeness, we have conducted a hierarchical task analysis .
Working closely with the Fundamentals in Laparoscopic Surgery (FLS) committee, Harvard Medical School and Tufts University, this project aims at developing and validating a virtual reality simulator for the FLS tasks (peg transfer, pattern cutting, ligating loop, suturing with intracorporeal and extracorporeal knot tying).
This project aims to design, develop and validate a Virtual Endoluminal Surgical Simulator (VESS) that can be used to train endoscopists in Endoscopic Submucosal Dissection (ESD). A virtual reality (VR)-based simulator with visual and haptic feedback for training in colorectal ESD is being developed, which the aim to allow trainees to attain competence in a controlled environment with no risk to patients. In this work, a newly developed application of the virtual simulator that promotes the endoscopists to perform and assess technical skills in ESD is being developed. Training tasks will be built based on physics-based computational models of human anatomy with tumors.
This project aims at developing and validating a virtual reality-based simulator for the laparoscopic gastric banding procedure. Preliminary clinical validation studies have been performed in 2010 at Harvard Medical School.
Natural Orifice Translumenal Endoscopic Surgery (NOTES) is an emerging surgical paradigm, where peritoneal access is achieved through one of the natural orifices of the body. It is being reported as a safe and feasible surgical technique with significantly reduced external scarring. Virtual Translumenal Endoscopic Surgical Trainer (VTEST™) is the first virtual reality simulator for the NOTES. Through collaboration with clinical leaders in the NOTES field, the VTEST™ simulator was designed to train surgeons to successfully complete a hybrid transvaginal NOTES cholecystectomy procedure.
