Researchers at the Sant'Anna School of Advanced Studies in Italy are developing a surgical tool that can squirm its way between organs and hold them in place while operating. This flexible arm is inspired by the arms of octopi.
The tool is flexible enough to find its way around organs but isn't too flexible -- it has an interior membrane that contains ground coffee, allowing it to stay pliable.
Many surgical tasks require the use of multiple instruments such as graspers, retractors, vision systems and dissectors. However these octopus arm-inspired surgical tools could give way to the creation of a surgical instrument that can be used to perform all of these tasks and more.
Bio-inspired technology is nothing new, but the innovation of life-saving surgical tools inspired by the earth's creatures is heartening to see.
