According to Xinhua news agency, Washington, July 17 (Reporter Lin Xiaochun) British researchers reported on July 17 that they have developed an "intelligent" scalpel that can tell doctors in a few seconds whether they are removing normal or cancerous tissue At present, doctors cannot judge whether the tumor has been completely removed by naked eyes In the case of breast cancer, about 20% of patients need to have a second operation, the researchers said Therefore, doctors often send patients' tissue samples for examination, which is time-consuming and may not be able to remove the cancerous tissue Zoltan taukchi of Imperial College of technology and others reported in the American journal Science Translational Medicine that many operations use electric knives, which burn tissues rapidly by electric current to reduce bleeding while cutting In this process, smoke will be generated Taokaqi et al Believe that these smog contain important tissue information, so they successfully developed an "intelligent" surgical knife (iknife) based on the electric knife, which is connected with a mass spectrometer the size of a refrigerator, and can carry out real-time mass spectrometry analysis on the smoke samples generated by surgery In the 81 patients tested, the accuracy of this "intelligent" scalpel was 100% Compared with the traditional postoperative diagnosis, the diagnosis time of this "intelligent" scalpel is only 3 seconds.
