Iknife

Medical device

An onkoknife, iKnife, or intelligent scalpel is a surgical knife that tests tissue as it contacts it during an operation and immediately gives information as to whether that tissue contains cancer cells. During a surgery this information is given continuously to the surgeon, significantly accelerating biological tissue analysis and enabling identification and removal of cancer cells. Electroknives have been in use since the 1920s and smart knife surgery is not limited only to cancer detection. In clinical studies the iKnife has shown impressive diagnostic accuracy - distinguishing benign ovarian tissue from cancerous tissue, breast tumour from normal breast tissue and recognises histological features of poor prognostic outcome in colorectal carcinoma. Furthermore, the technology behind iKnife - rapid evaporative ionisation mass spectrometry (REIMS) - can identify Candida yeasts down to species level.
