Human-controlled robot "surgeons" have been assisting doctors in operating rooms since 2000. However, the Single Site "wristed needle driver" that was created by Intuitive Surgical takes robotic precision to a whole new level. That's because its flexible "wrist" allows the instrument tip to move up to 45 degrees in all directions, enabling doctors to operate on organs like the uterus, without making large incisions that result in unsightly scars.
