A robot surgeon

NeuroArm, a robot has helped surgeons in Canada  to remove a tumour from page  Nickason, a 21 year-old woman' brain. Doctors controlled the NeuroArm from a computer workstation to guide the two-armed device through Paige's brain during a nine-hour operation. the NeuroArm is more precise and works with a magnetic resonance imaging (MRI) scan. It is able to move in far smaller increments than a surgeon's hand. According to DL Garnette Suther­land, who led the University of Calgary team that developed the robot, "Neu­roArm will improve surgical outcomes as it is less invasive and more delicate in its touch."
