Exploring video recognition models for force estimation in small bowel surgical retractions

Vision-based force estimation based on the laparoscopic video feed is a promising way toward force estimation of tissue retraction. A novel use of computer vision models has been proposed with a low-cost data collection pipeline. Since the proposed clinical usage does not require customized equipment, seamless integration to the existing surgical framework is possible. The experimental results additionally demonstrate potentials in the approach to pave the way for real-time haptic feedback and quantitative skill assessment.
