Adaptation to a dynamic visual perspective in laparoscopy through training in the cutting task.

Area of Science:

• Medical Training
• Surgical Simulation
• Mechatronics

Background:

• Laparoscopic surgery requires specialized skills developed through practice.
• Traditional laparoscopic training systems have fixed optical perspectives, hindering skill acquisition.
• Dynamic visual perspective is crucial in actual surgery but limited in conventional training.

Purpose of the Study:

• To propose and evaluate a mechatronic system for dynamic optical control in laparoscopic training.
• To enhance trainee adaptation to real-time visual perspective changes during surgical tasks.

Main Methods:

• A two-phase study comparing fixed optics with a mechatronic system for a cloth-cutting task.
• Trainees performed the cutting task with static and dynamically controlled visual perspectives.

Main Results:

• The dynamic optics system significantly improved trainees' ability to handle tasks with real-time perspective changes (p < 0.0025).
• Task quality and user performance were enhanced with the mechatronic assistant (p < 0.0001).

Conclusions:

• A new laparoscopic training method utilizing real-time dynamic optics via a mechatronic device was developed.
• This tool enables faster adaptation to dynamic visual environments, improving surgical readiness.
