On Earth, an infected abscess is fairly straightforward to treat: open and drain. On a spaceship headed to Mars or to an asteroid, however, the procedure could kill everyone onboard.
In zero gravity, blood and bodily fluids can’t be contained – making it impossible to perform surgery in space without contaminating the whole cabin. But for extended stays in deep space, trauma and other medical emergencies are very likely.
So researchers from Carnegie Mellon and University of Louisville began developing an astro-surgical tool that could help. It’s called the Aqueous Immersion Surgical System (AISS). New Scientist explains:
In order to determine if the system will actually keep blood inside the body and out of the surgeon’s field of view, the device is being tested aboard NASA’s zero-gravity C-9 aircraft -- where researchers will perform surgery on a pig heart and on an artificial coronary system filled with synthetic blood.
International Space Station astronauts might be increasing their stay from 6 months to a year. Right now, if a medical emergency happens, the only option is to evacuate the astronaut back to Earth.
