With patients becoming so demanding and fussy that even small slip ups by surgeons resulting into scarring is not acceptable. Paige Nickason, a 21-year-old Canadian woman with an egg-shaped brain tumor, found out first hand how robotic surgery assistants are allowing surgeons to perform the most delicate operations with quick accuracy. The successful removal of her tumor signifies a first for an image-guided robotic assistant in this kind of operation, and has patients at the University of Calgary lining up for related treatments.

A guiding a pair of robotic hands during a surgery enables an operating window microns-wide — 50 microns, in the case of the NeuroArm robotic surgeons used for Nickason's operation.
