How do you do surgery in zero gravity?
Very carefully. And it helps to have NASA’s latest toy.
You’ve probably seen videos of astronauts playing with water in space. No dripping or dropping here. Due to their inherent surface tension and the lack of gravity applying any external force, liquids tend to form into spheres and float around. Fun stuff.
But what about blood? Of gall bladder fluid? Or, yuck, pus from an infected wound? These are not materials you want floating around in your space capsule, or your face.
The Aqueous Immersion Surgical System (AISS) just might solve this problem. It is a saline-filled transparent box with airtight ports through which orthoscopic surgical tools can be passed.
Very clever and very cool.
