Roland Piquepaille writes "In a few years, telesurgery performed by multi-armed robots remotely controlled by real surgeons located hundreds or thousands of kilometers away will become commonplace. Today, Canadian doctors from the Centre for Minimal Access Surgery (CMAS) are developing the technology for NASA. Their goal is to build a portable robotic unit that would be used in space missions, war zones and remote areas within five years. So far, the experiments already done in Canada and for NASA are extremely encouraging. But read more for additional details and pictures of a real surgeon controlling such a robot."

      That's a HUGE user interface problem, actually.

        Light moves 300.000 km/s and the distance from western Europe to eastern USA is on the order of 6000 km, so minimum physically possible pingtimes would be about 40ms.

        What the they thinking of when they talk about doing this in OUTER SPACE for God's sake? Where would it be sensible to do this? In low-earth orbit they should be able to de-orbit in a few hours in an emergency. Further out, near the moon it's 3 seconds round trip. En-route to Mars; forget it.

        Wait till they can build a Known-Space-style autodoc.

    • This has really got nothing to do with NASA and space stations. Consider the potential for offshoring surgery. Indian/Chinese/whatever surgeons operating telepresence remote bots. All the hospitals will need are a few low-skill orderlies to strap the victims to the tables and give the bot a squirt of oil now and then. Should make for cheaper surgery and better profits for the health insurance companies.

      Sounds like whoring for a funny rating, but not so. There are millions to be saved in surgery bills $20/hr

    This is a very strong argument for tiered bandwidth - so ISPs can guarantee that surgical waldo packets take priority over, say, downloads of the latest release of an OS or a new movie.

        You take everything as a single indivisible step and don't rush until you know the outcome of the previous one.


        That doesn't work when you're doing surgery. The patient is under stresses that increase the damage to his body and the risk of unsatisfactory outcome (failure of the operation's goal, post-op infection, temporary or permanent impairment, or death) increase with every extra minute the operation takes.

        Surgery: Miniscule accurate movements. If something unexpected happens and the patient starts to bleed getting one thing even slightly wrong kills the patient.

        Only on /.

      • Mars doesn't move so much. Patients do. The heart beats, which makes EVERYTHING else pulsate. You know how on TV they open up the skull and the brain is just sitting there? Yeah, it doesn't do that.

        If you'd ever watched a surgeon you'd know how important instant feedback is. Surgeons operate by touch and sound as much as sight. "Okay, I'm feeling that I've cut through the dura and have reached brain... oops, that was a second and a half ago."
      • "OK, the cut went well. CLAMP!"

        "Uh, Doctor, blood pressure went to zero between the cut and the clamp."

    • Well, since the unit is being developed to perform surgery in space, as well, I imagine they'll be using dedicated video/data links. There's no real mention of what exactly they will be using, but I'd bet that "advanced telecommunications technology" doesn't mean internet.

      • The space application doesn't guarantee immunity from a big time lag--just the opposite. If NASA wants to use this for missions to the Moon or Mars, there will be a lag, and it will be quite noticible irregardless of how much they pay for their bandwidth.
        • The system would be totally impractical for earth-bound surgeons to use for Mars trips. Even the moon, with a second and half lag one way, would introduce some bad problems.

          But it seems obvious to me, at least, that this would only be usable with dedicated links, and not over the internet, which is what a lot of others seem to be saying here. I doubt very much that any of the engineers involved have even considered using the public internet (at least I hope they haven't! :-)

        • The space application doesn't guarantee immunity from a big time lag--just the opposite.

          The problem isn't just the lag.

          The problem is lag VARIABILITY and GAPS in data transmission.

          A space application has a fixed time lag and very low packet loss (through forward error correction - to an extreme degree if necessary). In the absense of jitter and the virtual absense of dropped packets, some degree of fixed lag can be taken into account.

          But removing jitter means enough buffering that your resulting fixed lag

        A QoS-enabled Internet would work just fine. And it's coming - unless misguided "Net Neutrality" laws throw the baby out with the bathwater.

        There are two aspects to "neutrality" and tiered bandwidth.

      I highly doubt that surgery would ever take place over the internet. It's just too unreliable to put someones life dependent on it. This kind of thing is far more likely to be used on dedicated point to point links.

    • What the maximum allowed network latency and thereby the maximum allowed operation distance be? Could somebody come with an answer?

      I wonder if it would depend on the doctor. Network FPS games seem to be a decent analogue to this with regards to latency. Some players adapt just fine, and others never really get it.

      It's not such a big deal now that all of them implement client-side prediction (which a surgical system might be able to do), but back in the days of Quake 1, it was a huge differentiator.

These systems would provide trauma-mitigation care during transport to a facility where more advanced care can be given.

    Advantages: robotics can be extremely precise. If programmed properly, it can compensate for any twitchiness on the part of the operator.

    But the disadvantages are significant: the feel isn't the same as performing the surgery for real. Now, for certain types of surgery that problem isn't a problem, but the human hand is actually quite sensitive to pressures and other types of feedback that I'm sure are quite invaluable to a surgeon (IANAS, however). A machine can provide some of that feedback through the link but the amount of feedback will be limited by the sensory capability of the machine.

    So, like many things, I can see this being useful for a relatively limited set of surgical operations, while for others "being there" will remain necessary.

    That said, if I have to choose between having this and having nothing at all (a battlefield comes to mind for such a situation), I'd rather have this and I'll take my chances with the limitations...

    • The problem of "feel" is being solved simultaneously to this remote manipulation technology, though the article may not mention it. Haptic [wikipedia.org] interfaces give mechanical feedback to the controls to convey sensations like texture and viscosity. Using a tool like this [sensable.com] I have virtually stirred syrup and cut open a human kidney. The former I can vouch as feeling almost indistinguishable from reality; you might have to find a more educated or psychotic person than myself to vouch for the latter.
