VR surgery (ie remote) was done already in the 90ies, as esp. need by the US navy in its submarines. This used "robots" of course.

AI assisted surgery is the current state of the art. The AI sees much more than the human eye.

And the robot is much better and smaller than the human hand. See microsurgery

I'm pretty sure full AI robot surgery can be done right now already. There's no technical gap missing.
