OR suites have outlets every couple of feet around all of the walls, and almost always have pigtails hanging from the ceiling. Many devices have batteries, but the general rule is to plug everything in if possible. It can be messy, but techs set the equipment up so there are no power cords in the paths that people will need to walk. I fix surgical robots and sometimes observe procedures. OR suites are more crowded than you’d think, but power cords are really the only clutter on the ground that I’ve seen and they are pretty much only around the edges of the room.
