Technology is transforming what our hospitals and medical practices will look like in years to come. Ask anyone on the street how they imagined the future of medicine to be in, say, one hundred years, and they are likely to say 'robots'. And they'd be right. But we don't have to wait a hundred years. They're already here, operating on people. This new three-part series sees Professor Robert Winston look at the new, cutting edge surgical robots in the UK and around the world. He questions how useful they are; whether they are just big, expensive toys, or whether they are really providing patients with a useful service. Professor Winston begins his journey as a very cynical observer; how could a robot ever take over that sacred, very human, relationship between a doctor and patient? But he has an open mind, and is willing to be convinced. The first installment features the extraordinary Canadian Neuroarm robot, which specialises in brain tumours. Not only can the surgeon see exactly what's going on inside the patient's brain without having to take the skull off, but they can feel it as well. The robot has a sense of touch.
