On November 27th, nearly one-third of the operations for removing breast cancer tumors were unable to completely eradicate the tumor. This ratio proves one thing: how difficult it is to remove a cancerous tumor if the surgeon relies heavily on medical images and other information collected before surgery. Zoltan Takats, a professor at Imperial College, said that trying to remove cancer tissue is as difficult as driving a closed eye. “For now, the information that surgeons can access is not direct information, but indirect information from preoperative tasks. And that means they will never know exactly what they are cutting.†For this medical problem, Takats provides an "answer", the so-called "iKnife", a surgical instrument that allows surgeons to know if the tissue they are removing is cancerous. The iKnife is an electronic scalpel that uses a charge to burn through human tissue. Electronic scalpels have been in use since the 1920s, but unlike previous electronic scalpels, iKnife has found a way to extract useful information from the volatilized body tissue. Traditional electronic scalpels simply absorb this vapor, and iKnife can introduce it into a mass spectrometer to analyze its chemical composition. By comparing the chemical characteristics of vapors with the characteristics of thousands of human cancerous and non-cancerous tissues, iKnife allows surgeons to know which type of human tissue they are removing. Typically, this analysis is done in a very short time of less than two seconds. The instrument is equipped with a touch screen monitor to display the results of the analysis and to inform the doctor via audio signals. Early tests have shown that this instrument can accurately identify other types of tissue in the surgical ward environment, and its R&D team is currently working on a medical -grade mass spectrometer that can be used in the operating room. According to Takats, clinical trials have shown that iKnife can help surgeons remove more cancerous tissue compared to existing electronic scalpel procedures, while also reducing damage to healthy human tissue surrounding the tumor. "This instrument will definitely reduce the rate of reoperation, but I don't know if it can reduce this ratio by 10%, 30% or 90%," he said. Takats pointed out that the benefits of removing more cancerous tissue are self-evident, such as reducing the chance of cancer recurrence. He said: "In the case of breast cancer, 30% of (surgical) cases have residual tumor tissue, and these tissues will develop into new tumors." He also said: "This is a very simple truth: you don't want cancer tumors to remain in the patient, and you don't want too much healthy tissue to be removed." He exemplified that in neurosurgery If the healthy tissue near the tumor is harmed, the result may be the patient's ability to "lose normal life." Takats said that the random human trial of iKnife is expected to begin in early 2016. Swabs are ideal for collecting large numbers of samples and quickly eluting samples. It immediately releases specimens into transport media and is widely used in molecular genetics, forensic science, clinical laboratories, and more.
