Robotics: How It Works

The da Vinci Surgical Robot allows the surgeons hand movements to be translated into more precise movements of micro-instruments. The robot cannot be programmed nor can it make decisions on its own. It is under the complete control of the surgeon at all times. Use of the robot also significantly reduces surgeon fatigue by allowing the surgeon to remain seated in a natural, comfortable position while operating.

3-Dimensional Optics

Standard laparoscopic surgery uses one single camera and limits a surgeon's vision to a 2-D view similar to watching your television. The da Vinci robotic camera consists of two high resolution fiber optic cameras which, like your eyes, produce a true 3-dimensional color picture available to the surgeon seated at the da Vinci console. Magnification of up to 12x can be achieved with these cameras whose position is precisely controlled by the surgeon. 

Robotic Micro-Instruments

Although visually similar to standard laparoscopic instruments, the robotic instruments have the additional advantage of being articulated. This means the instruments not only open and close but also fully turn and twist, allowing 7 degrees of motion. Unlike standard open surgical instruments these instruments are much smaller. Many of the jaws of the tools are shorter in length than your fingernail. This allows very small and precise movements and surgical cuts to carefully dissect out the prostate.
