abstract: Automatic surgical video analysis is pivotal in enhancing the effectiveness and safety of robot-assisted minimally invasive surgery. This study introduces a novel procedure planning task aimed at predicting target-conditioned actions in surgical videos to achieve desired visual goals, thereby addressing the question of ``What to do to achieve a desired visual goal?”. Leveraging recent advancements in deep learning, particularly diffusion models, our work proposes the Multi-Scale Phase-Condition Diffusion (MS-PCD) framework. This innovative approach incorporates multi-scale visual features into the diffusion process, conditioned by phase class, to generate goal-conditioned plans. By cascading multiple diffusion models with inputs at different scales, MS-PCD adaptively extracts fine-grained visual features, significantly enhancing procedure planning performance in unstructured robotic surgical videos. We establish a new benchmark for procedure planning in robotic surgical videos using the publicly available PSI-AVA dataset, demonstrating that our method notably outperforms existing baselines on several metrics. Our research not only presents an innovative approach to surgical video analysis but also opens new avenues for automation in surgical procedures, contributing to both patient safety and surgical training.
