Prepping robots to perform surgery

Robots are a fast-growing, diversifying $1 billion segment of the medical device industry. For example, many urologists performing prostate surgery view the movements of a robot as the best way to spare nerves crucial to bladder control and sexual potency. A robot's ability to deftly handle small tools also may lead to a less invasive procedure and faster recovery for a patient. In addition, robots can protect surgeons from physical stress and exposure to X-rays that may force them into premature retirement.
