The da Vinci robot consists of a console where the surgeon supervises the robot's every move; a garold which is placed by the patient's bedside, and which has four arms which the surgeon manipulates (one arm controls the camera, and three arms manipulate surgical instruments); and a high definition, three-dimensional video system. The surgical instruments needed for the procedure, such as scalpels, bovies, and scissors are mounted on the arms of the robot and are introduced into the patient's body through cannulas. The movements of the surgeon's hands are filtered in such a way that hand tremors are eliminated and then communicated to the instruments on the robot's arms. The main advantages of surgery by robot are greater precision due to miniaturization which means smaller incisions leading to less pain, less blood loss and faster healing. The Marvelous Illinois Da Vinci Surgical Robot The use of robots in surgery has come a long way in a very short period of time. The double-lens video camera used by the system gives a truly stereoscopic view of the situation inside the patient which the surgeon sees through two eye-holes on a monitor at his or her.

No wonder that the Ilinois da Vinci surgical robot has become the treatment of choice for such delicate procedures as prostatectomies and heart bypass surgery.
