Area of Science:

  • Pediatric Surgery
  • Surgical Simulation
  • Medical Device Development

Background:

  • Minimally invasive pediatric surgery is increasing.
  • Quantitative assessment of pediatric surgical skills is lacking.

Purpose of the Study:

  • Develop and validate a pediatric chest model for surgical skill assessment.
  • Quantify pediatric-specific surgical skills.

Main Methods:

  • Created a 3D-printed pediatric chest model with realistic anatomy.
  • Incorporated force-sensing and motion-tracking technologies.
  • Assessed 30 surgeons (16 inexperienced, 14 experienced) performing suturing tasks.

Main Results:

  • Experienced surgeons showed superior performance in task completion time, instrument path length, and applied force.
  • The pediatric chest model presented greater challenges than the conventional box trainer.
  • Sensor failures impacted motion measurement in 10 participants.

Conclusions:

  • The developed pediatric chest model is a valid tool for assessing pediatric surgical skills.
  • Further analysis of collected data will refine understanding of pediatric-specific competencies.
