Surgical blades 'Smart' Cancer Detection Network

 
VIVAlife - Scientists at Imperial College London has created a scalpel that can detect within seconds whether the dissected tissue is cancer or not. As reported by Reuters news agency, the discovery of the so-called iKnife scalpel surgery promises a more effective and accurate in the future.
The presence of iKnife allow doctors to cut an additional surgery to remove the cancerous tumor remaining. Tools that effectively combines electrosurgical knife-cut tissue engineering using hot-with Rapid Evaporative Ionization Mass Spectrometry (REIMS) has even been shown to distinguish between beef with horse meat.
Previously surgeons consider it impossible to see by naked eye where the tumor ends and the healthy tissue starts. As a result a number of cancer cells are left behind. One-fifth of breast cancer patients who underwent lumpectomy surgery are known to require a second operation.
The iKnife designed to overcome these problems by instantly providing an example of smoke from the dissected tissue using an electric current to see if it is cancerous or not. In the first study, published in Science Translational Medicine, iKnife tissue samples of 91 patients diagnosed with 100 percent accuracy rate.
Currently, tissue is removed and then sent to a laboratory for analysis with the patient's condition was still under the influence of drugs. However, analysis or test that takes about a half hour.
While iKnife provide feedback within three seconds. iKnife analyze biological information that is released from the burning of the network and compare the results with the analysis of biological fingerprint database tumors and healthy tissue.
One of the researchers from Imperial College, Zoltan Takats stated that it plans iKnife tested in a study involving approximately 1,000-1,500 patients with various types of cancer.
Takats itself has established firm based in Budapest Medimass to develop these products. He hopes to reach a partnership agreement with major healthcare technology companies to market iKnife to North America and Europe.
In making iKnife, Takats and his colleagues at Imperial College London spent about 200,000 pounds, or about U.S. $ 300 thousand. Takats explains, the cost will go down so iKnife produced commercially.
iKnife, Takats said, also has the advantage besides detecting cancerous tissue, which can identify the network with an inadequate blood supply as well as identify the type of bacteria in the tissue.
Received a positive
Meanwhile, Head and Neck Surgeons Hospital Southampton, England, Emma King, who was not involved in the study assessed, iKnife an interesting innovation and promising technique for any kind of surgery. Nevertheless, he still wanted to see what if iKnife used in randomized clinical trials.
Positive response came from the UK Health Minister, Lord Howe. He said that could be useful iKnife how patients and care by reducing the number oranag kesehataan requiring cancer surgery a second time. (Adi)
