Aren’t you glad that in this day and age, you are able to enjoy advances in the world of medicine as well as surgery, so much so that the average life expectancy for most humans across many countries have increased by a significant number of years? Of course, the more modern and sedentary lifestyle would also mean we tend to pile on the pounds around our waists easier than ever before, which is definitely not something that doctors recommend we do. Having said that, you can be a fitness buff and eat the most organic diet possible, and yet fall foul of a divine master plan when the doctor calls you and asks, “Do you have a moment to meet up with me in private?” Not everyone will have to go through a similar fate though, and for those of us who need to undergo surgery, how about having some robots crawling around on your body?
Researchers in Zurich intend to do that by working on near microscopic robots that are said to assist surgeons in delicate surgeries. This particular robot would feature a retractable needle that will allow it to probe around, and the body of this particular robot measures all of a mere quarter-millimeter in diameter, and if you were to take that into a relative comparison, it would be roughly equal to 4 human hairs or so. In other words, this unique robot is as thin as a surgical scalpel, with a needle that is just as sharp.
Considering this robot’s size, it is safe to assume that with this robot running the show (albeit as an assistant), any surgery could eventually end up as non-invasive, and of course, minimal. It will be different from a conventional robot, as it is far too small to carry a battery to power itself, and neither can it tote a “drive” to get around. “The OctoMag” is what powers this robot, as it uses a bunch of electromagnets around the patient’s head to get the job done. Increasing or decreasing the force of the electromagnets by minute amounts would push or pull the robot through the body. Of course, additional research needs to be done before this robot is deemed worthy to be used on humans.
