Re: More a tele-operated manipulator.
"Not really - for the 'hands-on' philosophy, the surgeon's hands are on the surgical tool itself, so the surgeon maintains direct contact with the tools and patient. Since the tool is connected to the robot, as the surgeon manipulates it, it backdrives the robot and the robot senses the position of the tool and forces applied to determine whether and how much it should push back to keep the tool within the correct area."
My use of terminology has been inexact. I had presumed there was some kind of force feedback built into the system.
For those of a certain generation we'd call this a Waldo. A force-feedback teleoperator (now with added computerized limit stops).
"Surgical planning can be done from scans of the patient for true patient specific surgery to take into account the variation in shapes and sizes and bits not conforming to the standard model. And, yes, bits of patient do move during surgery, but there are tracking devices that can monitor that and update the plan to take into account the movement (admittedly easier for orthopaedic surgery where we're talking about solid objects than for soft tissue which can distort)."
That's sort of my point. While those points *could* have been used to argue "Robots are just not flexible enough to handle the real time problems of internal surgery in real time." But I'm not current on the SoA and was not certain this was the case yet.
You seem to be saying that those factors can be taken into account *today*.
No one denies that a modern Surgeon is a highly skilled (and highly rewarded) medical professional.
It's perfectly clear that the ability to deliver *consistent* reliable surgical procedures at reasonable speed and cost will bring about a revolution in the profession. This is obvious to anyone thinking about the social consequences of new technology.
I'm quite sure the surgical community is fully aware of what has happened historically to jobs whose core skills are manual dexterity and eye/hand co-ordination and been de-skilled by automation. The core skill of a printer was their ability to read a page of hot lead set text back to front and upside down (or not if they worked for the Guardian). Now it's a niche skill used by a small group of people who still do things that way for customers who still *want* it done that way.
It's a clever bit of mechanical engineering and (to a layman) very non-intuitive in design, which *might* reduce surgical trauma and improve stay times in hospital.
However had the goal of full automated surgery been pursued from the project in 1997 I would expect they would have a working robot surgeon by now.
I remain a pessimist about the *full* application of the technology. My original point stands. Surgeons will resist *full* person-out-of-loop fully computer controlled surgery more vigorously and longer than the Fleet Street print unions resisted the introduction of journalists being able to set their own type.
No one wants to take a status or pay cut but you don't see much hot metal being used in *any* newspaper anywhere these days.
I'll get excited when a person can be handed over to surgical team *minus* the surgeon and they run a full operation. I'd settle for one that takes 2x as long as a human (to begin with) but has a higher *average* success rate due to its better consistency.
To anyone thinking such resistance is unethical as a violation of their training to do the best for their patient I would point out that a robot surgeon eliminates the need to *be* a patient of a human surgeon so it's not like they are blocking an improvement to patient care or more cynically Turkeys don't vote for Christmas.
