A bizarre ‘magnetic tentacle robot fire‘ that can pass into the narrow tubes of the lungs to take tissue samples could help save lives, a new study shows.
Experts at the University of Leeds have created the device, which consists of external magnets and a ‘tentacle’ — a thin polymer tube containing metallic particles.
The so-called ‘tentacle’ is highly flexible and measures just 0.07 of an inch (2 mm) in diameter, about twice the size of the tip of a ballpoint pen.
Like something from a horror film, the tentacle would slowly enter the mouth or nose of a patient while they are under general anaesthetic.
Guided by the external magnets, it could reach some of the smallest bronchial tubes in the lungs — and could be used to take tissue samples or deliver cancer therapy.
