This study introduces automated methods to objectively assess robotic surgery skills. These models accurately distinguish between expert surgeons and trainees, aiding skill development.

Area of Science:

  • Robotics
  • Surgical Education
  • Medical Technology

Background:

  • Robotic surgery use is increasing across medical specialties.
  • Current training methods struggle to differentiate operational and surgical skills.

Purpose of the Study:

  • To develop objective methods for assessing robotic surgery skills.
  • To track trainee progress in robotic surgery to proficiency.

Main Methods:

  • An automated system recorded instrument motion and video data monthly.
  • Statistical models were created to differentiate skill levels between experts and trainees.
  • Four basic surgical skills were analyzed: suturing, manipulation, transection, and dissection.

Main Results:
