Brazilian researchers have developed a new medical equipment using fluorescence detection, helping to grasp the metastasis route more accurately, improve the operation efficiency and provide patients with a more optimal treatment.
According to local media reports, the device is developed by the San Carlos Institute of Physics of University of Sao Paulo. The main components include two cameras, a group of infrared device used for detecting fluorescence and capturing images and a display. A mobile device is fixed to the bracket, and the doctor can conduct handle operation.
Some substances are irradiated with light of a specific wavelength, and fluoresce after absorbing energy. According to the researchers, the new equipment would deliver fluorescent powder. And using light with specific color to shine the cancer site, then the light send by fluorescent powder with different colors were captured by cameras. Thus surgery experts can determine the location of the sentinel lymph node in real time.
Lymph gland is a very important tissue in the body's immune system. Clinically, the first lymph node metastases must pass through is called the sentinel lymph node.
According to reports, the conventional pathological diagnosis depends on the doctor's subjective judgment on lymphoid tissue slice, but fluorescence detection technology shows higher sensitivity and accuracy and helps to improve surgical safety. Other advantages of this new device include that it can also generate color images and it can record the process of the surgery to be used for subsequent analysis and so on.
