    Area of Science:

    • Robotics in Surgery
    • Motor Learning Theory
    • Surgical Training Simulation

    Background:

    • Robot-assisted minimally-invasive surgery (RAMIS) presents advantages over open surgery but requires optimized training methods.
    • Current motor learning theories offer potential for RAMIS training, yet a gap exists between simple movement studies and complex surgical tasks.
    • Understanding how surgeons adapt to dynamic challenges is crucial for effective RAMIS training.

    Purpose of the Study:

    • To investigate the impact of time-dependent force and motion perturbations on learning a surgical pattern-cutting task.
    • To evaluate the effectiveness of perturbation-based training in enhancing surgical skill acquisition and adaptability.

    Main Methods:

    • Utilized the da Vinci Research Kit for a circular pattern-cutting task with 54 participants.
    • Two experiments were conducted: one with force perturbations and another with motion perturbations.
    • Participants were divided into control (no perturbations) and experimental (1 Hz perturbations) groups.

    Main Results:

    • Training with perturbations allowed participants to overcome challenges and improve performance during practice.
    • Post-training performance was not negatively impacted after perturbations were removed.
    • Motion perturbation training conferred an advantage in adapting to subsequent perturbations.

    Conclusions:

    • Periodic perturbations can effectively enhance robot-assisted minimally-invasive surgery (RAMIS) training.
    • This training approach improves adaptability without compromising the learning of the core surgical task.
