Active and Passive Haptic Training Approaches in VR Laparoscopic Surgery Training

Area of Science:

• Medical Simulation
• Surgical Training
• Human-Computer Interaction

Background:

• Laparoscopic surgery is a common minimally invasive procedure requiring precise instrument control.
• Current training relies on expert supervision, which is time-intensive and limited.
• Ensuring instrument power control is critical to prevent internal organ damage.

Purpose of the Study:

• To develop and evaluate VR-based haptic training approaches for laparoscopic surgery.
• To transfer expert surgical hand movements to trainees using a VR simulator with force feedback.
• To compare the effectiveness of active versus passive haptic training methods.

Main Methods:

• Development of a VR laparoscopic surgery simulator with a guidance force display.
• Implementation of two haptic training approaches: active (error-triggered guidance) and passive (continuous guidance).
• Validation of training approaches through simulated laparoscopic surgery tasks.

Main Results:

• Both active and passive haptic training approaches were validated in the VR simulator.
• The study identified distinct differences in skill transfer between the active and passive training methods.
• The VR simulator effectively demonstrated the applicability of the proposed training strategies.

Conclusions:

• VR-based haptic simulators offer a viable solution for laparoscopic surgery training.
• Active and passive training methods provide different mechanisms for skill acquisition.
• Further research is needed to fully understand the implications of each training approach for surgical proficiency.
