Robotic surgery uses robotic arms controlled by a surgeon to perform surgery through small incisions. This allows 10x magnified high-definition 3D views and instruments with movements beyond what the human hand can do, increasing precision. The Da Vinci and Zeus systems are examples used for cardiac, gastrointestinal, gynecological and other procedures. Benefits include less scarring, faster recovery and shorter hospital stays, while disadvantages include safety questions and high costs compared to traditional surgery.
