Pulling his face away from an immersive 3D headset looking deep inside a patient's lung, doctor Sasha Stamenković recounted the final steps of an operation using robots to remove a tumour.
"We've done some very, very intricate operating today," said the 60-year-old consultant thoracic surgeon.
"We've saved a lot of lung, we've gone around some really, really small vessels and really small airways."
He was addressing three surgeons from another English hospital observing Stamenković using the new da Vinci 5 robotic-assisted surgical system, made by US company Intuitive.
The equipment will arrive in their operating theatre later this year, part of a drive to increase the use of robotics in keyhole surgery across the UK's National Health Service.
