Magnetic camera controlled by magnetic field
British and German researchers say they have successfully built the first control system for the endoscope.
When a patient swallows a camera larger than a candy, the device moves through the intestines and transmits the image to an external receiver worn on the patient's side. This device contains data, so doctors can analyze and detect hemorrhage or internal tumors.
If the camera is moved naturally, it is not suitable for the examination of the esophagus and stomach due to time travel so fast: the time the camera moves in the esophagus is only about 3-4 seconds, can only capture Get 2 or 4 images per second and when it reaches the stomach, it falls very quickly down the wall beneath the stomach.
With the new control system, physicians can stop the camera in the esophagus, move it up or down, adjust the camera rotation as required ... In addition, the doctor can also look at the picture. photo in the stomach wall.
The endoscope is no larger than a candy, the patient swallows it and the doctor controls its motion with a magnetic field.
But how to "drive" the camera as you want inside the body? According to the researchers, it is thanks to a device made of chocolate-sized magnetic field. When examining a patient, physicians may carry the device from the field in their hand, move it up or down along the patient's body, and the camera will move as required.
Tests show that magnetic-field cameras can be placed in the esophagus for 10 minutes even when the patient is sitting.
