U.S. develops miniature esophagus scanner to detect cancerous lesions in advance
Recently, American scientists have developed a new type of miniature esophagus scanner. It is hoped that this technology developed in the United States will become a simpler way to scan the symptoms of Barretts oesophagus, so that the disease that can cause cancer can be discovered early. Unlike current imaging technology, this device can be used when the patient is conscious, and it only takes a few minutes.
So far this device has only been tested in a small number of patients. When people suffer from Barretts oesophagus disease, cells in the lower part of the esophagus will become abnormal due to long-term acid reflux, which puts them at a high risk of developing esophageal cancer. The doctor can scan those symptoms with an endoscope, but it must be done in a sedated state.
This scanner uses infrared imaging
Doctors can use this to look for signs of Barretts oesophagus disease
This new device is contained in a capsule the size of a vitamin pill, with a thin wire attached to the outside. Inside the capsule is a rapidly rotating laser probe, and the infrared rays it emits are reflected back from the inside of the esophagus. Doctors can see 3D images of the esophagus on the screen, and the microscopic details far exceed the endoscope effect. When a patient swallows this capsule, it enters the stomach in the same way as taking pills, and can then be pulled back into the esophagus using a thin thread. The device was tested on 6 patients known to have symptoms of Barretts oesophagus and 7 healthy volunteers. The researchers said the images clearly showed the changes in cells in those patients.
Professor Gary Tirner, one of the study ’s collaborators, said that this technique is cheaper than endoscopy, and avoids the need for sedatives, special equipment, and professional training, and the microscopic details shown in the pictures can avoid living tissue slice . Professor Tilner said: "The pictures of the esophagus produced by this device are some of the best pictures we have ever seen. We were initially worried about losing a lot of data, but we were pleasantly surprised to find that it brought us a complete esophageal wall. Microscopic images. "Professor Tierna added that this device can help doctors determine who is at risk and may find cancer at an early stage that is easier to handle.
Slicer and dicer(meat dicer) are used in different fields of food industrial such as for meat, cheese, vegetables, fruits etc. Helper`s slicer and dicer seies are applied in both restaurant and industrial plant. To produce portioned bacon, the Rib chopper will help. To make vegatable and meat mixture for dumpling production, QD02 vegetable dicer will be the best choice.
In addition to them,we also supply the cubing machines.
