About Intuitive’s Products:

The da Vinci^® Surgical System consists of a surgeon’s viewing and control console having an integrated, high-performance InSite^® 3-D, high definition vision system, a patient-side cart consisting of three or four robotic arms that position and precisely maneuver endoscopic instruments and an endoscope, and a variety of articulating EndoWrist^® Instruments. By integrating computer-enhanced technology with surgeons’ technical skills, Intuitive believes that its system enables surgeons to perform better surgery in a manner never before experienced. The da Vinci^® Surgical System seamlessly and directly translates the surgeon’s natural hand, wrist and finger movements on instrument controls at the surgeon’s console outside the patient’s body into corresponding micro-movements of the instrument tips positioned inside the patient through small puncture incisions, or ports.
