An intelligent surgical knife has been developed that can detect cancerous tissue as it cuts through it in less than three seconds. The iKnife has been developed by researchers at Imperial College London, and uses smoke from tissue to sense whether or not it is cancerous.
The smoke, which is usually extracted away, is caused by heat from electrosurgical knives that vaporise the tissue as they cut through it. Imperial's Dr Zoltan Takats realised this smoke would be rich in the biological information and so connected an electromagnetic knife to a device which can sense the chemicals that hold information about the state of the tissue.
