Thousands of cancer patients across Wales could soon be operated on by robotic arms controlled by surgeons. The robotic arms will be used by the NHS to perform procedures for some prostate and gynaecological cancers, and some procedures on the digestive system, kidneys and bladder. The jointed arms with surgical instruments at the end are used to perform keyhole surgery, and are moved by a surgeon who controls them via a computer. Cameras on the arms let the surgeons see what is happening, and they can zoom in and magnify the area being operated on. How safe can it be to use Robots to operate human beings ?
