In this paper we describe our efforts to develop a new strategy for providing assistance using haptics in a virtual environment when training for a motor skill. Using a record and play strategy, the proposed assistance method will provide closest possible replication of expert’s skill. We have defined a new paradigm called “Haptic Attributes” where we(More)
OBJECTIVE To develop and establish effectiveness of simulation-based robotic curriculum--fundamental skills of robotic surgery (FSRS). METHODS FSRS curriculum was developed and incorporated into a virtual reality simulator, Robotic Surgical Simulator (RoSS). Fifty-three participants were randomized into an experimental group (EG) or control group (CG).(More)
BACKGROUND A standardized scoring system does not exist in virtual reality-based assessment metrics to describe safe and crucial surgical skills in robot-assisted surgery. This study aims to develop an assessment score along with its construct validation. MATERIALS AND METHODS All subjects performed key tasks on previously validated Fundamental Skills of(More)
OBJECTIVES To assess the face validity of Robotic Surgery Simulator (RoSS), a novel virtual reality training platform for the da Vinci Surgical System (DVSS). METHODS Urologic surgeons, fellows, and residents attending the 2009 American Urologic Association Annual Meeting in April 2009 were invited to an orientation session with RoSS. Participants(More)
BACKGROUND Recent incorporation of simulation in surgical training necessitates developing validated platforms for training and assessment. A tool should fulfill the fundamental criteria of validation. OBJECTIVE To report the ability of a simulation-based robotic training curriculum-Fundamental Skills of Robotic Surgery (FSRS)-to assess and distinguish(More)
OBJECTIVE To determine the overall cost effectiveness of surgical skills training on Robotic Surgical Simulator (RoSS). METHODS This study evaluates the cost analysis of utilizing RoSS for robot-assisted surgical training, at Roswell Park Center for Robotic Surgery. Trainees were queried for time spent on the RoSS console over a period of 1 year, starting(More)
OBJECTIVE To validate robot-assisted surgery skills acquisition using an augmented reality (AR)-based module for urethrovesical anastomosis (UVA). METHODS Participants at three institutions were randomised to a Hands-on Surgical Training (HoST) technology group or a control group. The HoST group was given procedure-based training for UVA within the(More)
Recent growth of daVinci Robotic Surgical System as a minimally invasive surgery tool has led to a call for better training of future surgeons. In this paper, a new virtual reality simulator, called RoSS is presented. Initial results from two studies - face and content validity, are very encouraging. 90% of the cohort of expert robotic surgeons felt that(More)
