Onkoknife, iKnife, or intelligent scalpel ( English: Jedi knife, onkoknife; Hungarian: onkokés, intelligens sebészi kés) is a surgical knife, which 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 removal of virtually all cancer cells. Electroknives have been in use since the 1920s and smart knife surgery is not limited only to cancer diseases, but the iKnife is limited to cancer cell detection in the vapor given off, however, since it can not properly detect and identify the type of bacteria found in tissues so well.
