Wauw! Is there anything Batman can't do? I mean, performing surgery with an insterile butcher's knife, that's incredible!
Holy Bat Fact! - It's one of the simplest surgical procedures there is. All you're doing is cutting a hole in someone's windpipe to allow them to breathe normally if their trachea has been crushed, say. What you typically do after that is stick a drinking straw in there. They can then breathe without using their nose or mouth.
