Robot can perform 2-hr surgery in 2.5 min, scientists claim
US-based researchers have developed a machine they claim reduces the duration of two-hour manual skull drilling to 2.5 minutes. Using CT scan images, the robotic drill can be programmed to avoid touching nerves, veins and arteries. The procedure reduces anaesthesia given to patients and time the wound is open, thereby decreasing surgical cost and chances of infection, researchers said.
