This Snakelike Robot Slithers Down Your Lungs and Could Spot Cancer

"Researchers in the United Kingdom have developed an autonomous, snakelike robot designed to slither down human lungs into places that are difficult for medical professionals to reach," reports the Washington Post. The tool "could improve the detection and treatment of lung cancer and other pulmonary diseases."In a medical paper released in the journal of Soft Robotics last week, scientists from the University of Leeds unveiled a new "magnetic tentacle robot," which is composed of magnetic discs and is roughly 2 millimeters thick — about double the size of a ballpoint pen tip — and less than a-tenth-of-an-inch long. In the future, the robot's use could be expanded to help doctors better, and more thoroughly, investigate other organs, such as the human heart, kidney or pancreas, they said.... The robot is still 5 to 10 years away from showing up in a clinical setting, researchers said, but the device comes on the heels of a fleet of other robotic innovations allowing doctors the ability to better scan a patient's lungs for cancerous tissue. They are designed to ease a task doctors have long struggled with: reaching the inner recesses of the human body, for diagnostic and treatment purposes, without causing damage or using invasive procedures.... [I]ts smaller size and magnetic composition would allow it to shape-shift more easily and better navigate the intricate shape of a lung's network of airways, which can look like a tree.... Once at its desired location, the robot could ultimately have the capability to take a tissue sample or deliver a clinical treatment.... Nitish V. Thakor, a professor of biomedical engineering at Johns Hopkins University, said the autonomous robot is "very novel and interesting technology" that could become potentially useful in areas outside the lungs, most notably the heart. The device's autonomous capability is its unique factor, he said, and has the capability to change invasive surgeries. "I can imagine a future," he said, "where a full [cancer-screening] CAT scan is done of the lungs, and the surgeon sits down on a computer and lays out this navigation path of this kind of a snake robot and says: 'Go get it.'
