Head-to-Head Comparison of Three Virtual-Reality Robotic Surgery Simulators

BACKGROUND AND OBJECTIVES: There are several different commercially available virtual-reality robotic simulators, but very little comparative data. We compared the face and content validity of 3 robotic surgery simulators and their pricing and availability. METHODS: Fifteen participants completed one task on each of the following: dV-Trainer (dVT; Mimic Technologies, Inc. , Seattle, Washington, USA), da Vinci Skills Simulator (dVSS; Intuitive Surgical Inc. , Sunnyvale, California, USA), and RobotiX Mentor (RM; 3D Systems, Rock Hill, South Carolina, USA). Participants completed previously validated face and content validity questionnaires and a demographics questionnaire. Statistical analysis was then performed on the scores. RESULTS: =. 99). CONCLUSION: All simulators demonstrated evidence of face and content validity, with significantly higher scores for the dVSS; it is also the least costly (80, 000 for the simulator), although it is frequently unavailable because of intra-operative use. The dVT and RM have similar face and content validity, are slightly more expensive, and are readily available.
