  1. IKnife Vi Tran BME 281 November 20, 2013

  2. Challenges of Tumor Removal -Difficulty in establishing exact boundaries of cancerous tissue -Any uncertain tissue is sent to laboratory to analyze -30 minute process, time consuming

  3. IKnife • “Intelligent” Knife • Surgical knife that instantly identifies cancerous tissue as it cuts through tissue • Takes about 1 to 3 seconds • Designed by ZoltanTakatas, a Hungarian chemist at Imperial College in London in 2013

  4. How It Works -Consists of a electrosurgical knife that is connected to mass spectrometer -Heat is generated through knife as it cuts through tissue -Smoke is produced and is analyzed by mass spectrometer -Since cancerous tissue has more phospholipids and different ion composition than healthy tissue the machine analyzes the chemical composition of the smoke to differentiate between the two tissues

  5. Results -Results highly successfully -Tested products in two ways -Researchers took tissue samples from 302 patients and performed an analysis using Iknife -Was able to correctly differienate tissue -Used in operating room on 91 random patients -Results highly accurate

  6. Benefits and Future -Able to instantly identify cancerous tissue in operating room -Eliminates need to send tissue to laboratory for analysis -Minimizes surgery time -Costs 200,000 pounds(approximately $380,000 US currency) to make this device -Price will drop once it becomes commercially produced -Researchers are currently working to improve this device -Clinical trials will probably occur in 2 to 3 years -As newer developments are being made, this will help lives of many people
