NASA Performs Zero-G Robot Surgery for Mars, Iraq 106

Posted by Zonk from the not-sure-i'd-trust-that dept.
An anonymous reader writes "With rapid-response surgery needed in Iraq and super-long-distance medicine a far-off necessity for a manned trip to Mars, NASA recently sent eight astronauts, roboticists and surgeons on its 'Vomit Comet,' pitting real doctors against new robotic ones. As if the prospect of a portable robo-OR deploying to Iraq by 2009 weren't enticing enough, one of the surgeons on board promised this in his flight blog: 'So far, surgery by hand is still the most efficient way to get the job done in a mobile, extreme environment. But robots are advancing rapidly... The solution that roboticists are working on now is to CAT scan a patient's entire body and beam the results back to Earth. Then a surgeon could program an operation and beam it back to upload into a robo-surgeon, which could carry out procedures like a player piano.'"

    How do they plan on performing surgery to someone on mars? There is a rather large prorogation delay, even if data is sent at the speed of light, this is not fast enough to perform surgery.

        Right, but the idea is that simply recording motions from the doctor and playing them back with a robot won't work.

        The player piano only works because a piano is a predictable, static thing. It responds in exactly the same way to the same stimulus, every time. The body is not. Fast-acting feedback mechanisms are important for all sorts of things, from maintaining balance to doing surgery.

        If we're using musical metaphors: if you take a choir and teach them a piece, then give them earplugs and ask them to perform it, they'll drift out of tune rather quickly; singers rely on constant aural feedback to stay in tune with each other.
        • So it's tough. Preferably the computer would be programmed to recognize things like bleeders and react accordingly.

          We're working on machines that can operate on an unrestrained eyeball - lids are clamped out of the way, but the eye is free to move. That's pretty awesome right there.
          • That machine is still only having to compensate for two degrees of freedom (phi, theta), though. It's frickin' cool, but not something I'd want doing general-purpose surgery where any number of things can happen.

    Forgive me for possibly being naive, but wouldn't it possibly be a LOT more practical to simply keep a highly-skilled physician on board the mission?

    After all, ocean ships have been doing this for hundreds of years. Today, Antarctic expeditions usually have a surgeon on hand, along with a minimally stocked OR, because it's virtually impossible to get anything to or from the interior regions of the continent in the wintertime.

    Given that a good portion of the research NASA does is biological in nature, I imagine that there are quite a few individuals who are already qualified for this role. Sending a trained doctor to Mars seems like a no-brainer.

    On the other hand, sending a CAT Scan machine up into orbit (and then to Mars) seems hilariously over the top. On the list of big and bulky machinery, CAT Scan machines are pretty high up there. Why not send a locomotive and some track up so that we can drive around on the surface once we get to Mars? After all, they're fast and energy-efficient!

    On the other hand, if they were developing a similar technology, but remained focused on keeping it cheap and portable, the applications for it would be HUGE. It'd still be fantastic on the battlefield, and could also be used in remote regions (especially in developing nations) where the local population cannot support having highly-specialized doctors in their area.
