The surgical robotic device enhances the interaction between the surgeon, the surgical instruments, and the patient. Complex maneuvers not possible with either a traditional laparoscopic approach or with open techniques are easily accomplished with this technology. During robotic surgery, the surgeon is seated usually a few feet away from the operating table. The surgeon views the patient's anatomy through a screen that produces 3-D images in high resolution. The robot that operates on the patient is controlled by the surgeon who carefully maneuvers a pair of instrument controls. On the patient side, two robotic surgical arms are fitted with small 5 to 8 mm instruments and a small camera that can provide a detailed view of the patient.
