Technology over time has evolved so drastically, that things that were not just a part of a sci-fi movie few years back is now practice daily. It might seem another plot of a sci-fi movie in which robots are injected in your body to perform surgery. But it is not science fiction, but a reality. With the advancements in nanotechnology, the doctors are able to do use snake robots that carry tiny cameras, scissors and forceps in order to perform a surgery.
Scientists and doctors are using the creeping metallic tools to perform surgery on hearts, prostate cancer, and other diseased organs. These snakebots are powered by tethers that humans control. But experts say the day is coming when some robots will roam the body on their own.
According to Dr. Michael Argenziano, the cardiac surgery chief at New York-Presbyterian Hospital and Columbia University Medical Center, “It won't be very long before we have robots that are nanobots, meaning they will actually be inside the body without tethers. It's like the ability to have little hands inside the patients, as if the surgeon had been shrunken, and was working on the heart valve”. He is one of those that pioneered robotic heart surgery more than 10 years ago.
