Hands-free system puts surgeons in control of their operating rooms
March 2011. Sunnybrook Hospital, Toronto. A surgical oncology team is working to remove a complex tumour entwined around the patient’s adrenal glands and pancreas.
At one point in the delicate procedure, Dr. Calvin Law puts down his scalpel, turns to a computer screen displaying an image of the tumour and, without touching anything, makes a gesture with his gloved hands. The image rotates, and three Waterloo Engineering grads in the operating room exhale in unison.
