NASA Performs Zero-G Robot Surgery for Mars, Iraq

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.'"

      You're already in trouble if you need open heart surgery. The risks are "acceptable", considering the alternatives.

      The mars scenario, on the other hand - the idea of scanning someone and waiting for advice won't work. Even if they could be scanned in zero seconds, and a diagnostic reached in zero seconds, the time delay is between 10 and 50 minutes..Heck, look what happens with only a 4 minute delay http://www.jamesoberg.com/2004marsconquest.html [jamesoberg.com]

    • On a serious but related side when using those robots on battlefield, a robot does not suffer from stress in a dangerous environment and will therefore stay at 100% efficiency until actually damaged (at this point, a human doctor won't be very usefull either).
      • Worse, a damaged human surgeon is likely to take out two surgeons (IE him and somebody to work on him), while you discard the robot and stick a spare(that you hopefully have) in.

    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.

      Surgeons are becomming specialized - what if the operation is a complicated one? A telepresence capable robot would be a better option.

      Given enough development, a robotic surgeon can do more complex tasks faster than a human. Like the one designed to be able to work on a mobile human eye. A heart would be easy after that. Imagine, open-heart surgury while the heart is still beating.

    • 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?

      Not really - because after months-to-years of no surgical practice, he isn't going to be a highly skilled physician anymore. On top of which, there isn't going to be enough room on the crew who isn't wearing at least two hats, which mitigates against having more than average skill (if that) as a surgeon.

    I'll wait until Amazon rolls out the sequel to its Mechanical Turk concept, the Mechanical Doc. You pay thousands of people $1 each to perform incisions, clamp stuff, remove this, stitch up that, and voila! Open source surgery! After all, one pair of eyes may not be able to spot a problem but thousands of eyes should be able to correct any ailment.
     
  • They can't be doing this in that big ol' fancy space station they got up there? Hmm, I thought this was the kind of stuff it was built for.
  • One of the problems that human surgeons sometimes have when working from CAT scans is that the organs inside the body tend to move around and change shape after you cut it open. As the incision spreads, pressure is relieved and of course fluids can be released, changing the internal geometry. Are they really going to steer the scalpel with the pre-incision geometry?

    I suppose for massive trauma injuries, it might be OK, but it seems like interactivity is a pretty strong general requirement for 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.

    • >" 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. Things happen quickly, the surgeon needs feedback, etc. "

      The delay isn't 10 seconds - its between 10 and 50 minutes, depending on the relative positions of the two planets. By the time they see the cuts not in the right place, the problem will have solved itself - the patient will be dead.
