Robot-Assisted Laparoscopy in Minimally Invasive Surgery

Laparoscopic surgery is minimally invasive, which offers the advantages of reduced pain, shorter hospital stay, and quicker convalescence for the patients. Unlike open surgery, laparoscopic surgery needs only several small incisions in the abdominal wall to introduce instruments like scalpels, scissors, etc., and a laparoscopic camera, such that the surgeon can operate using camera visual feedback only. The inconveniences of laparoscopic operations lie mainly in the difficulties in mutual understanding between the surgeon and the camera assistant who maneuvers the laparoscope according to the surgeon's instructions. Another problem with laparoscopic surgery is that the camera image may become unstable in a long operation due to fatigue of the camera assistant.
