Back in 2015, I wrote about where surgical technology is headed.
New evidence to support that prediction comes from Todaysmedicaldevelopments.com
The story is about tiny, origami-like robots, folded in ice. When the ice capsule is ingested, the ice melts and the device unfolds, whereupon it can be propelled and manipulated by external magnetic force.
This technology is obviously in its very early, formative stages. But I would bet that the technical hurdles will be overcome and that this type of robotic surgery could be widespread in the future.
