This video demonstrates the Basic Demonstration of Da Vinci Robot - How Surgical Robot Works? Compared to traditional techniques of open surgery and laparoscopic surgery, the very small incisions created by robotic surgery drastically reduce patients' time in the hospital and their risk of infections. The use of high-definition 3D cameras allows surgeons close-up views of areas they aren't able to see during open surgery. Fully articulating robotic arms mimic the movement of hands, allowing surgeons to have greater dexterity and control than is possible with conventional laparoscopic instruments.
