Robotic surgery is a minimally-invasive surgery technique using a computer that remotely controls small instruments attached to robotic arms. The small instruments mean that incisions in your body can be much smaller than those needed for standard surgery using hand-held tools.
 
Once inside your body, a thin tube with a camera attached allows your surgeon to view magnified images of the inside of your body in real-time. He can then make the necessary movements and cuts using the computer to translate his hand motions into very precise actions.
