High-tech scalpel makes brain surgery less risky
The "smart scalpel" developed by a researcher named David Oliva Uribe in Brussels, Belgium doesn't look or even work like a conventional scalpel. It has no edge, has a sensor-rich sphere at the tip, and instead of having the capability to cut people open, it can differentiate between cancerous tumors and normal brain tissue. A surgeon simply has to swipe it across the brain's surface to get a visual or an auditory result about the tissue's status in half a second. The tool's especially useful when locating early stage tumors, which still look similar to healthy tissue.
