Does training on a virtual reality robotic simulator improve performance on the da Vinci surgical system?

Area of Science:

• Robotics in Surgery
• Surgical Simulation
• Medical Education

Background:

• The da Vinci surgical system (dVSS) is widely used in minimally invasive surgery.
• Effective training methods are crucial for developing proficiency in robotic surgery.
• Surgical simulators offer a controlled environment for skill acquisition.

Purpose of the Study:

• To evaluate the effectiveness of the Mimic dV-Trainer (MdVT) simulator in improving surgical skills on the dVSS.
• To compare simulator-based training with traditional dVSS training for inanimate object exercises.

Main Methods:

• Twelve trainees underwent training with the MdVT simulator, while a control group (10 residents, 1 fellow) trained directly on the dVSS.
• Participants performed standardized exercises on the dVSS, with performance scored for timing and accuracy.
• Training protocols involved pre- and post-training assessments on the dVSS for the MdVT group.

Main Results:

• Both groups demonstrated significant improvements in Letter Board and String Running exercises (timing and accuracy).
• The MdVT group showed enhanced performance in Pattern Cutting and Peg Board times.
• The dVSS-only group achieved significant improvements in Knot Tying time and Peg Board accuracy.

Conclusions:

• The MdVT simulator training yielded comparable improvements to dVSS-only training across several exercises.
• The MdVT simulator can be a valuable tool for surgical residents and students.
• Simulator training may facilitate the transition from skill acquisition to proficient performance in robot-assisted surgery.
