Area of Science:

  • Surgical Technology
  • Medical Simulation
  • Robotic Surgery Training

Background:

  • Telementoring in robot-assisted minimally invasive surgery (RMIS) is crucial for skill development.
  • Current training methods may not fully leverage advanced visualization and guidance technologies.

Purpose of the Study:

  • To evaluate the use and effectiveness of three-dimensional (3D) proctoring tools, or 'ghost tools,' in realistic surgical training scenarios.
  • To develop quantitative metrics for assessing how proctors utilize the capabilities of these 3D ghost tools.

Main Methods:

  • Seven proctor-trainee pairs performed surgical tasks (dissection, suturing) using 3D ghost tools on the da Vinci Xi Surgical System in a porcine model.
  • Proctor performance was objectively measured via hand movements and button presses, supplemented by post-study questionnaires.

Main Results:

  • Proctors actively utilized advanced ghost tool features, including 3D hand movements, wrist movements, finger gestures, and bimanual motions (p < 0.001).
  • Median ghost tool excursion distances were 57.6mm (x-axis), 31.9mm (y-axis), and 50.7mm (z-axis).
  • Both proctors and trainees rated ghost tools as effective mentoring tools, with trainees finding them more helpful (p < 0.05).

Conclusions:

  • Proctors effectively leverage the augmented capabilities of 3D ghost tools in simulated clinical training.
  • 3D ghost tools are confirmed as effective mentoring tools, supporting prior findings.
  • Advanced technologies like 3D ghost tools show significant potential to enhance RMIS telementoring and training.
