Summary
Augmented reality telestration significantly enhances minimally invasive surgery (MIS) training by improving trainee gaze behavior and reducing errors. This visual guidance system, iSurgeon, leads to better surgical performance and outcomes.
Area of Science:
- Surgical Education
- Medical Simulation
- Human-Computer Interaction
Background:
- Minimally invasive surgery (MIS) training requires trainees to interpret complex visual information.
- Current verbal guidance methods from experts are limited.
- A novel augmented reality (AR) telestration system, iSurgeon, offers real-time visual guidance.
Purpose of the Study:
- To analyze the effect of AR telestration on gaze behavior during MIS training.
- To evaluate the impact of telestration on surgical task performance.
- To compare AR telestration with traditional verbal guidance.
Main Methods:
- A randomized-controlled crossover study involving 40 MIS-naive medical students.
- Performance of 8 laparoscopic tasks under telestration and verbal guidance conditions.
- Eye-tracking (Pupil Core) to measure gaze latency, convergence, and collaborative gaze convergence.
- Assessment of errors and standardized performance scores (OSATS).
Main Results:
- Significant improvements in gaze latency, gaze convergence, and collaborative gaze convergence with iSurgeon.
- Markedly fewer errors in tasks performed with telestration (0.18 vs. 1.94).
- Higher performance scores in laparoscopic cholecystectomy with telestration (OSATS: 29/35 vs. 25/35).
Conclusions:
- AR-based telestration effectively improves surgical performance in MIS training.
- Telestration enhances trainee gaze behavior by reducing fixation time and increasing gaze convergence.
- This technology offers a promising approach to improve surgical training outcomes through gaze guidance.
