    Area of Science:

    • Surgical Technology
    • Medical Simulation
    • Robotics in Medicine

    Background:

    • Robotic surgery adoption is increasing in general surgery.
    • Current training requires simulator tasks and minimum scores.
    • Limited data exists on task proficiency and time investment.

    Purpose of the Study:

    • To analyze critical robotic surgery tasks for injury prevention.
    • To develop predictive models for task mastery based on initial attempts.
    • To estimate the number of simulator attempts needed for proficiency.

    Main Methods:

    • Used de-identified data from dV-Trainers® simulator over 12 months.
    • Analyzed camera manipulation and energy use tasks (Camera Targeting, Energy Dissection, Energy Switching).
    • Extracted metrics: Time to Complete, Economy of Motion, Misapplied Energy Time, Blood Volume Loss. Used mixed linear models.

    Main Results:

    • Over 26,000 minutes of simulator use by 30+ users.
    • Average of 8 attempts per exercise per user.
    • Models predict 4-5 attempts needed for 80% proficiency in key metrics.

    Conclusions:

    • dV-Trainer® virtual reality simulators aid general surgeons in robotic surgery.
    • Simulator data can predict time and effort for proficiency in critical tasks.
    • Surgeons needing more attempts may benefit from additional training like proctoring.
