Electrosurgical resection is a neurosurgery technique in which a surgeon uses an electric knife to burn body tissue. The process releases tissue molecules into the air in the form of smoke. A recent article from Tampere University of Applied Sciences says researchers have developed a measuring system that analyzes the smoke and distinguishes healthy from malignant tissue.
The device contains an electric knife that produces flue gases from the tissue and uses a machine learning system to analyze it. In a recent study, the device detected malignant tissue with 83% accuracy. The device could one day lead to more precise excision of tumors to stop the spread of cancer and save healthy tissue.
