SurgicalMamba: Dual-Path SSD with State Regramming for Online Surgical Phase Recognition

In three linesSurgicalMamba, a Mamba2-based model, performs online surgical phase recognition with O(d) per-frame cost. Three components address domain-specific challenges: dual-path SSD separating long/short-term regimes, intensity-modulated stepping adapting effective rate, and state regramming enabling cross-channel mixing. SOTA results: 94.6%/82.7% on Cholec80, 89.5%/68.9% on AutoLaparo, 238.74 fps on single GPU.
