Robots Approved For Cardiac Surgery

An anonymous reader writes "CNN has an article up on a new robotic heart-surgery system. By making 4 relatively small incisions into the patients chest the da Vinci Surgical System, guided by real surgeons, uses its pencil sized "tools" to conduct several different heart procedures including closed-chest coronary bypass surgery. By operating on a patient with their chest closed, patient recovery times have reduced from weeks to just days. Despite the robotic surgery taking longer than traditional operations, this reduced recovery times makes the robotic surgery cost less overall than traditional open heart surgery. Fortunately, if anything goes wrong with the robot, the human surgeons can jump right in and pick up where the robot has stopped. Already the robot (in place in over 130 hospitals world wide) has been FDA approved for Mitral Valve repair surgery. More insightful info on the da Vinci System here." It's not the first such system, either.

      Is this a robot? Or is this a human surgeon performing surgery with a very sophisticated set of tools?

      From the topic description:
      ...if anything goes wrong with the robot, the human surgeons can jump right in and pick up where the robot has stopped...
      From the CNN article:
      ...totally robotic operation...

      These imply the human surgeons can just sit and watch while the robot goes about its work, but Da Vinci's web site says otherwise. I don't think there's any artificial intelligence involved, but I see where the confusion lies.

      "but think about it, how many times have you screwed up a math problem? now how many times has you TI83?"

      First off, I don't have a TI-83. Real men have TI-92+s. Or a slide rule. Which I also have.

      Secondly, what if the robot was running off, say, one of those famously screwy Pentium 90's or 100's with the floating point bug?

      Third, what if it runs on Windows 95?

      That being said, I'd still rather have the robot than some med school flunky that got his or her degree from some small Caribbean country.

    A lot of times when doctors go to operate on someone with heart problems, they discover other defects or abnormalities with the heart and surrounding vessels. Will a robotic system that is minimally invasive create "tunnel vision" so that doctors are unable to see other potential problems?

    ...or else we will have a new generation of assassins who hack in the hospital network and just accidentally puncture your heart. I mean really, this is a bit scary - especially because based on my experience many doctors do not exactly know what is happening on their computer and how to keep it secure - and to make sure no-one plugs any device on their network or any software on their computer during the visit....and even if the computer is not networked, do you really think it would be impossible for someone to slip in a device providing wireless access to that machine. Has anyone noticed any articles on these issues?

    What do you think is scarier, having your chest peeled open like a book, or the alternative. As someone whose father just recently went through open heart surgery, I can say the process would be nerve racking either way.

    And while the surgery is bad, the recovery is probably worse. Painful, long, and frustrating. Anything that can shorten the recovery process is a wonderful thing, IMHO.

    When it comes to something that needs to be that robust, I want a control system consisting of highly reliable real-time (not pseudo-realtime like embedded distros) microcontrollers.

    I want parts designed to last 20 years, not something that could fail in one due to a motherboard failure, or at any time due to a hard drive failure. Software just doesn't cut it here.

    It is of course horrible that someone was killed by this less intrusive surgery, when they might have lived with the more intrusive and more often performed traditional sternum-cracking surgery.

    IANAMD, however I am certain it is not the first time that a new surgical technique designed to be less risky for the patient was actually more risky because of the novelty it presented the surgeons performing it. There's no way to leapfrog the novelty of the technique, but in the long run, for the general public, it will be less risky because it is less intrusive.

    We don't know anything about the trial - so let's not guess about rates. I'm just saying it's very bad when such an accident (occurring just a few weeks ago) is not worthy of mention in a long news article or TV program covering the device. Especially when it clearly appears to be the result of procedural error - this isn't someone's hand slipping. It should (rightly) draw new attention to the doctor, the device, and the underlying techniques, so it's very spooky when the news covers the device without ever mentioning it's just been involved in a patient death under questionable circumstances.

  13. Lower risk of Staf Infections? by wideBlueSkies · · Score: 4, Insightful

    My wife lost her father a couple of years ago.

    He had a triple bypass, and was up and around his room the next day. We were like "way to go dad!".

    The day after that he had a fever. Within a week he was in a coma, and 2 1/2 months after the operation he was gone. It was horrible. And all because he caught a Staf infection.

    It could be that maybe a surgical implement wasn't as clean as it sould be... more than likely, he just caught it from bacteria floating around in the air. He was on the table for more than a few hours.

    I hope to god that advances like this can keep someone else from going through the hell that he (and we) went through. The way I see it, the less invasive the procedue it, the less likely it is that an infection will occur.

    The article you cite states unequivocally that preliminary investigations found no mechanical fault in the device. If the reports indicated that the robot's arms spontaneously began making stabbing motions without input from the surgeon, then it would be important for the news outlets to report this incident. Surgeons can make mistakes, whether they are working with their own hands or controlling robotic ones.

    I, for one, would much prefer to be operated on using this new system--the electronics damp out tremors, and I don't have to worry about a surgeon sneezing and lacerating my intestine. The trauma of major incisions is eliminated, saving me from weeks of hospital food, pain meds, and severe scarring.

    Surgeons will take time to become accustomed to this new system. Without a gaping incision, it is harder to see what's going on. There are new failure modes possible. A nick in the aorta is immediately obvious in conventional surgery, not so much so under these conditions. There may also be a 'novelty' penalty. This is a new technique, so there aren't really any experts in the field who have performed thousands of procedures with these devices. There is a learning curve.

    Nevertheless, medical decisions are usually made on the basis of a risk calculation. If there are fewer overall complications and deaths, then I'll accept 10 robot-related deaths per year in exchange for the prevention of 100 lethal post-op infections due to poor wound healing.

    That case clearly shows the flaws with this technology... It made the surgeon lazy. He expected the robot to just 'do what it should' with no problems. He didn't check for internal bleeding. The patient died because of it.

    You're joking, right?

    Look, this thing isn't a "robot" in any real sense -- it's not taking away control from the doctor, it's a sophisticated tool which has the potential to do as much for surgery in the next few decades as the laproscope did in the last few.

    If the doctors start skipping steps, it's their fault, not the tool's. Like certain other people in this thread, you're applying Windows logic ("It should have done this for me and covered my ass!") in a UNIX situation -- the tool is meant to be used by someone who understands it and knows what they're doing.

    If some newbie rm -rf's his filesystem, it's his fault, not the OS's.
