Robot performs surgery without help from humans

A robot has operated on a pig without human help. The machine successfully performed keyhole surgery on a pig, attaching organs in a range of different animals. And it did so without the help of a human, for the first time. Scientists hope that it can help bring about fully automated operations on humans by similar robotic systems. The Smart Tissue Autonomous Robot (Star) carried out the delicate keyhole - laparoscopic - surgery, which involved connecting two ends of an intestine, in four animals.
