This document discusses robotic surgeries. It begins with an introduction that defines robotic surgery as using robots in the operating room to assist surgeons. It then covers the history and classifications of robotic surgery systems. The three major robotic surgery systems - da Vinci, Zeus, and AESOP - are described in detail. The applications of robotic surgery are discussed, including cardiac surgery, gastrointestinal surgery, gynecology, and others. The advantages of robotic surgery for both patients and surgeons are provided. Some disadvantages like cost and safety questions are also mentioned. In conclusion, the document states that while feasibility has been shown, more randomized trials are needed to fully evaluate the efficiency and safety of robotic surgeries.
