The iKnife is a new intelligent surgical knife that can detect, within seconds, whether cells are cancerous. Developed by Zoltan Takats from Imperial College, London, the iKnife uses electrosurgery to heat up tissue quickly and minimize blood loss and a mass spectrometer that analyzes chemicals in the tissue. In the study, the iKnife was tested on samples collected from 302 patients who had undergone surgery. The tissues contained both malignant and benign samples and the iKnife was able to determine the type within 3 seconds of each surgical cut. The technology will reduce surgical time and the need for follow-up procedures since it will help surgeons determine and remove all of the cancer cells in one visit.
