That is not how ai works. Such algorithm would not make it to an actual surgery. Even humans make mistakes. The advantage The point is to get the model to perform better than humans.
Surgical robots -- at least the ones that actually exist and work today -- are designed more like traditional safety-critical robotics platforms and less like a one-off case study for a nice visualization/table for an end-to-end deep RL paper. There is no "the model".
