UK developed a diagnostic cancer robot capsule
Release date: 2007-02-06
The UK has developed a capsule for diagnosing cancer. Recently, British scientists have invented a capsule-like device that can enter a person's body, detect a tumor, and then send the information to a computer outside the body. It can only eat and diagnose cancer. The study received £1.8 million in funding from the European Union and the results have been used in some large hospitals in the UK.
Robot capsules have many advantages over similar technologies. The miniature camera it carries will capture about 40,000 images of the intestines. Through these pictures, doctors can check the presence of tumors in the human stomach from a computer. In addition, because the picture taken by the camera can be instantly transmitted back to the computer, once the task is completed, the robot does not need to be recycled, and the patient can drain it to the toilet. The capsule is based on a capsule endoscopic image diagnostic system (pill-cam). Pillcam uses a capsule-like camera to see if it is inflamed in the colon, but only takes photos of inflammation, and the new robotic capsule detects the tissue in the intestine and distinguishes between cancerous tissue and healthy tissue. In addition, the device is capable of emitting light and relies on the reflection of light in the tissue of the intestine to find the tumor. Experts say that cancerous tissue usually absorbs more light because it creates a network of blood vessels to "feed" the tumor.
In addition, through the computer screen, the doctor can control the robot to stop and closely examine the suspicious organization. Previous photographic equipment could only be moved by the muscles of the digestive tract, and doctors could not control their movements outside the body. That is to say, just sitting in the train compartment and watching the scenery outside, you can't look back and look at it again. Researchers expect that this revolutionary device will free patients from painful biopsy and surgery. Prior to this, doctors must use these two methods to determine whether the gastrointestinal tract has cancer.
Professor Yan Guozheng, director of the Department of Information Detection Technology and Instrumentation at Shanghai Jiaotong University, has developed a “full gastrointestinal detection robot†for 4 years. The patient only needs to swallow a “robot pill†and have a bp machine on the waist. The data logger can go straight home to live, eat, and the digestive tract information will be monitored by the "pill" for 24 hours and sent to the recorder. After the entire digestive tract is monitored, the pill is discharged from the anus and is used for one-time use without recycling. —— Information from: Meditech Medical Network
