Robotic surgery, also called computer-assisted surgery or robot-assisted surgery, is designed to improve on advances in minimally invasive surgery by offering practitioners a high-tech view inside the body and more precision in the actual procedure. One of the most common robotic surgery products is the da Vinci Surgical System. Main drawbacks often cited include the high cost of the equipment and the steep learning curve for surgeons to become skilled at using the system. At the same time, surgeons say da Vinci offers several major advantages over traditional laparoscopic equipment. A stereo camera gives them a 3-D view of the organs, rather than the flat view of single-camera setups, and makes it easier to maneuver the instruments. Because the surgeon sits at a console several feet from the patient, procedures can be performed in relative comfort, and the computerized controls automatically compensate for hand tremors that can develop in a fatigued surgeon.
