The future is nearly here

Nanobots to clean out your systems.

Directly attacking cancer cells and the like.

Tool-wielding robots crawl in bodies for surgery

PITTSBURGH (AP) — Imagine a tiny snake robot crawling through your body, helping a surgeon identify diseases and perform operations.

It's not science fiction. Scientists and doctors are using the creeping metallic tools to perform surgery on hearts, prostate cancer, and other diseased organs. The snakebots carry tiny cameras, scissors and forceps, and even more advanced sensors are in the works. For now, they're powered by tethers that humans control. But experts say the day is coming when some robots will roam the body on their own.

"It won't be very long before we have robots that are nanobots, meaning they will actually be inside the body without tethers," said Dr. Michael Argenziano, the Chief of Adult Cardiac Surgery at New York-Presbyterian Hospital and Columbia University Medical Center in New York.
