Area of Science:

  • Surgical Simulation Technology
  • Pediatric Surgery Training
  • Minimally Invasive Surgery (MIS)

Background:

  • Surgical simulation is vital for surgeon training and evaluation.
  • A gap exists in simulators specific to pediatric minimally invasive surgery (MIS).
  • Pediatric MIS requires distinct fine motor skills compared to adult MIS due to motion scaling differences.

Purpose of the Study:

  • To test if motion scaling differences in a virtual reality simulator can differentiate skill proficiency between pediatric and general surgeons.
  • To validate a novel surgical simulator for pediatric MIS training.

Main Methods:

  • Developed a virtual reality intracorporeal suturing simulator with adjustable motion scaling for adult and pediatric MIS conditions.
  • Recruited pediatric and general surgeons as participants.
  • Measured performance using metrics like time, errors, movement smoothness, and gesture proficiency.

Main Results:

  • Pediatric surgeons significantly outperformed general surgeons in pediatric simulation conditions (P < .05).
  • No significant performance difference was observed between groups in adult simulation conditions.
  • Motion scaling effectively differentiated skill levels based on surgical specialty.

Conclusions:

  • Pediatric surgeons possess specialized skills for MIS, necessitating dedicated training simulators.
  • The developed simulator and its motion scaling feature are validated as effective training and evaluation tools for pediatric MIS.
