    it's more fun to do an endoscopy with a controller-it's a robot, technically, but when you're performing the procedure, you can pretend you're playing "Small Intestine Wars." (for doctors only of course)

  2. Three Dimensional Robot? by NitsujTPU · · Score: 3, Funny

    This is TRUELY revolutionary by relation to all of those 2 dimensional robots I see around.

    So, how does the doctor work with a 3 dimensional robot? Do you draw funny glasses on him?

  3. College paper has further coverage of Zeus company by jasonla · · Score: 3, Informative

    I attend UC Santa Barbara, and I work on the student newspaper, the Daily Nexus. We did an article on the technology and the company responsible for it a long time ago when Computer Motion made it's first attempt at telesurgery. Here's the article, yes, that's my name in the byline.

    We use these at work and they are very good -- Intuitive Surgical and Computer Motion both have systems that are getting use in ORs all over the place.

    The only drawback is the cost and training, but once you've spent the million dollars to get it, you open up a lot of opportunities for surgical education and easing the burdon on doctors (as well as removing all notions of "distance" from the question of timely assistance).

    For those wondering about the voice control, it only recognizes a dozen commands, and is totally speaker-independant. You'd say "Aesop...Move in" and it will move the camera in a few millimeters. The nice thing is that you can save positions and pricisely jump back and forth at looking in different areas in a half-second. It does have pressure sensors, so you can't do too much acidentally.

    Also, realize that sometimes you can spend literally 16+ hours on one surgery -- having the robot do the direct manipulation means you can switch surgeons every few hours or get up and walk around without letting go of the surgical instruments and possibly abrading something while handing them off.

    After watching a few dozen of these surgeries, i'd honestly say that i'd rather have my gall bladder removed by hermes/aesop/Zeus/daVinci than by a surgeon's hands...

      According to the article, the size of the incision required is much smaller that you could ever have if you needed to fit your hand in the opening.

      They are the same size as any other laparoscopic openings -- about big enough for two fingers. The robot isn't making any difference to the recovery time or incision, it is mostly an aid to the surgeon who is already doing laparoscopic procedures (and is already used to doing surgery from a 2d TV image).

      You're right about scaling of motions -- right now it isn't such a HUGE deal (although the fine control is handy as I said in being able to rest wihtout moving instruments) but in the future the same tech will be used for more and more precise surgeries that aren't even attempted today...

  5. 2nd Hand Experience by Pave+Low · · Score: 4, Informative

    My girlfriend is a PHD student, and she is currently doing research in medical technology. Recently she's had a demonstration of this device. After that demonstration, they were allowed to handle the machine and try some manipulations.

    From what I understood:
    1. This is not an intelligent robot, but a tool for the surgeon. Sensors are connected to the surgeons hands and arms, and they are transmitted to the operational device. It still is the surgeon which does the operation.

    2. Resistance, which I saw mentioned in one of the other responses, is simulated to the surgeon doing the operation. Thus, a more 'natural' feel is created.

    3. This device and devices like it are great tools for Minimal Invasive Surgery (MIS). Because the opening doesn't have to be large at all, and devices can be sterilized, this greatly reduces the risk of infection.

    4. If developments continue along this line, and there is no reason to believe they won't, operation rooms may become obsolete for many operations: a closed sterile device is pressed against the area where the opening has to come. All that has to be sterile is the insides of the operation device.

  6. What exactly is a "Robot"? by timeOday · · Score: 3, Insightful

    To me this machine sounds very much like a back-hoe, except that it makes motions smaller and more precise instead of larger and more powerful.

    Why can't they put something like this in the International Space Station to do experiments instead of expensive, risky humans?

    Actually, a robot can have limitless degrees of freedom. Your fourth degree would be wrist rotation, for example. A fifth would be forearm extension, etc.
