In robotic surgery the surgeon uses a high-resolution 3D stereo viewer to watch a high magnification image of the operation, in natural color and with normal depth of field. The surgeon uses the a console whose master controls maneuver four robotic arms, which hold the patented flexibly jointed instruments and a high-resolution endoscopic camera. The instrumentsí jointed-wrist design exceeds the natural range of motion of the human hand; motion scaling and tremor reduction further refine the surgeonís hand movements. The patient is actually operated on by the patient-end instruments controlled by the surgeon.
This kind of surgery is usually performed with the surgeon outside the actual operating room. It reduces the size requirement of the incision and that means reduced trauma to surrounding nerve and muscle tissue. It permits microsurgery in places where a normal surgeonís hands and instruments are too large.
