The surgeon controls the instruments and the camera from the operating room using a
console. Putting his fingers in the master controls, the surgeon can operate every one of the
four arms of the da Vinci at the same time while glancing through a stereoscopic HD
monitor that truly puts him inside the patient, giving him a superior, more point by point 3-
D perspective of the operating area than that provided by the human eye. Each move he
makes with the master controls is recreated definitely by the robot. Whenever it is
mandatory, the surgeon can even change the size of the robot's moves: If the surgeon
chooses a three-to-one scale, the tip of the robot's arm will show movement only for one
inch for each three inches according to movement of the surgeon’s hand. Furthermore, due
to the design of console, the surgeon’s hands and eyes are in every case splendidly lined up
with his perspective of the surgical area, limiting fatigue of surgeon.
