Summary
This study validated the dV-Trainer, a virtual reality simulator for robotic surgery training. It proved effective, with experts outperforming novices, establishing its utility for surgical education.
Area of Science:
- Surgical Simulation
- Medical Education Technology
- Robotic Surgery
Background:
- Robotic-assisted laparoscopic surgery is increasing, driving demand for effective training.
- Novel training methods are crucial to meet the growing need for skilled surgeons.
Purpose of the Study:
- To establish face and construct validity of the dV-Trainer, a virtual reality simulator.
- To assess the simulator's suitability for training robot-assisted surgery.
Main Methods:
- A comparative cohort study with 42 participants divided by robotic experience.
- Participants performed exercises twice to measure performance parameters for construct validity.
- Face validity was assessed via participant questionnaires post-exercise.
Main Results:
- Experts significantly outperformed novices in "time to complete" and "economy of motion".
- The simulator's training capacity received a high rating (4.6/5).
- High realism ratings were given for graphics, instrument movement, interaction, and depth perception.
Conclusions:
- The dV-Trainer virtual reality simulator demonstrated established face and construct validity.
- It is considered a highly useful tool for training residents and specialists in robotic surgery.
