They once play remotely restrained functionings now robots seem set to be the physicians of the future. Tim Adams investigates

Like all everyday supernaturals of technology, the longer you watch a robot act surgery on a human being, the more it begins to look like an inevitable natural wonder.

Earlier this month I was in an operating theatre at University College Hospital in center London watching a 59 -year-old man from Potters Bar having his cancerous prostate gland removed by the four dexterous metal arms of an American-made machine, in what is likely a glimpse of the future of most surgical procedures.

The robot was being controlled by Greg Shaw, a consultant urologist and surgeon sitting in the far reces of the chamber with his head under the pitch-black hood of a 3D observer, like a Victorian marry photographer. Shaw was steering the weapons of the remote surgical tool with a fluid smorgasbord of joystick assure and foot-pedal pressure and amplified instruction to his theatre unit standing at the patient's place. The surgeon, 43, has performed 500 such procedures, which are particularly useful for pelvic activities; those, he does, in which you are otherwise” searching down a penetrating, dark loophole with a flashlight “.

The first part of the process has been to” dock the cart on to the human “. After that, three surgical tools and a video camera, each on the end of a 30 cm examination, have been inserted through small incisions in the patient's abdomen. Over the course of an hour or more Shaw then talks me through his actions.

” I'm just going to clip his vas deferens now ,” he speaks, and I involuntarily wince a little as a insignificant robot pincer side, amplified 10 seasons on screens all over the operating theatre, comes into view to permanently cut off sperm quantity.” Now I'm trying to find that sweet discern where the bladder participates the prostate ,” Shaw speaks, as a weaken probe gently strokes aside blood vessels and finds its acces across the surface of the burly part on the screen, with very human delicacy.

After that, a mesmerising rhythm develops of clip and cauterise and slouse as the velociraptor pairing of” monopolar arcked scissors” and” fenestrated bipolar forceps” is run in tandem- the amazingly overdone movements of Shaw's entrusts and arms dividing and closing tiny blood vessels and ruby-red connective material deep within the patient's pelvis 10 ft away. In this mode, slowly, the opaque walnut of the prostate surfaces on screen through tiny plumes of smoke from the cauterising process.

This operation is an example of a clinical visitation of a procedure pioneered in German hospices that aims to preserve the fine building of tiny guts around the prostate- and with them the patient's sexual purpose. With individual patients still under anaesthetic, the prostate, pocketed up internally and removed, is likely to be frozen and couriered to a lab at the main infirmary area a mile away required to determine whether cancer exists at its sides. If it does, it may be necessary for Shaw to cut away some of these critical nerves to make sure all find of malignancy is removed. If no cancer is found at the prostate's perimeters the nerves can be saved. While the prostate is dispatched across township, Shaw expends a minuscule fish hook on a robot arm to deftly sew bladder to urethra.

The Da Vinci robot that Shaw is squandering for the purposes of our operation, made by the American firm Intuitive Surgical, is about as “cutting edge” as robotic state currently get. The PS1. 5m machine facilitates the UCH team to do 600 prostate actions a year, a four-fold raise on previous, less accurate, manual laparoscopic techniques.

Mostly, Shaw does three functionings one or two days a week, but there have been goes, with collaborators absent, when he has done five or six epoches straight-from-the-shoulder.” If you attempted to do that with old-fashioned pelvic surgery, craning over individual patients, you would be really hurting, your shoulders and your back would grab up ,” he says.

There are other collateral advantages of the technology. It lends itself to accelerated and efficient set both because it holds a 3D movie of all the operations conducted, and enables a virtual-reality collection to be plugged in- like discovering to fly an aircraft exerting a simulator. The most important help nonetheless is the greater safety and fewer complications the robot delivers.

I wonder if it changes the mental concerning the relationship between surgeon and patient, that tangible intimacy.

Shaw does not believe so.” The skill itself feels like driving ,” he adds.” But that 3D imagination is very immersive. You are get lots of information and very little distraction and you are seeing inside the patient from 2cm apart .”

There are, he adds, still diehards doing prostatectomies as open surgery, but he experiences it hard to believe that their patients are fully informed about the alternatives.” Most people come in these days asking for the robot .”

If a report produced this month on the future of the NHS is anything to go by, it is likely that” asking for the robot” could increasingly be the norm in hospices. The interim conclusions by the Institute for Public Policy Research's long-term investigate into the future of health- was presided over by Lord Darzi, the discriminated surgeon and former ambassador in Gordon Brown's government- was of the view that many affairs traditionally performed by doctors and harbours could be substituted by technology.

” Bedside robots ,” research reports hinted, may soon be employed to help feed patients and move them between wards, while” rehabilitation robots” would assist with physiotherapy after surgery. The centuries-old hands-on concerning the relationship between physician and patient would unavoidably change. “Telemedicine” would monitor vital signs and chronic conditions remotely; on-line consultation would be routine, and someone arriving at A& E” may begin by undergoing digital triage in an automated rating collection “.

Even the consultant's increased wisdom will be annulled. Machine-learning algorithms fed with” big data” would soon be employed to” utter more accurate diagnosings of diseases such as pneumonia, breast and surface cancers, heart diseases and mind cases “. By cuddling a process to achieve” full automation” Lord Darzi's report is planned that PS12. 5bn a year merit of NHS staff time( PS250m a week) would be saved” for them to deplete interacting with patients”- a notion that sounds like it would be better written on the side of a bus.

While some of these estimates may sound far more than the imagined decade apart, others are already a reality. Increasingly, the data from sensors and implants quantifying blood sugars and stomach rhythms is collected and fed instantly to remote checks; in London, the contentious aviator strategy GP @Hand has viewed more than 40,000 people make the first steps toward a” digital health interface” by signing up for on-line consultation accessed through an app- and in the process, de-registering from their bricks-and-mortar GP surgery. Meanwhile, at the sharpest intention of healthcare- in the operating theatre – robotic systems like the one used by Greg Shaw are already attesting the report's prediction that machines will carry out surgeries with greater finesse than humans. As a founder of robotic surgical skills, Lord Darzi knows this better than most.

In a way, it is surprising that it has taken so long to reach this part. Hands-off surgery was firstly developed by the Military members at the end of the past century. In the 1990 s the Pentagon wanted to explore ways in which enterprises at M* A* S* H -style field hospitals might be performed by robots controlled by surgeons at a safe interval from the battleground. Their investment in Intuitive Surgical and its Da Vinci prototype has given the Californian firm- evaluated at $62 bn- a virtual monopoly, strenuously policed, with 4,000 robots now operating around the world.

Jaime Wong MD is the consultant lead on the R& D program at Intuitive Surgical. He is also a urologist who has been using a Da Vinci robot for more than a decade and watched it derive from original 2D showings that involved more spatial guesswork, to the current much more manoeuvrable and all-seeing version.

Wong still enjoys examining traditional open surgeons witnessing a robotic functioning for the first time and” watching the admiration on their fronts at all the things they did not quite realise are located in that area “.

In the next stage of development, he insures artificial intelligence( AI) and machine learning representing an important role in the techniques.” Surgery is becoming digitised, from likeness to fluctuation to sensors ,” he alleges,” and everything is decoding into data. The organizations have a tremendous amount of computational ability and we have been looking at segmenting procedures. We trust, for example, we can use these processes to shorten or abolish accidental traumata .”

Up until very recently , Da Vinci, having plagiarized a march on any rivalry, has had this field practically to itself. In the coming year, that is about to change. Google has, naturally, developed a adversary( with Johnson& Johnson) called Verb. The digital surgery scaffold- which promises to” compound the ability of robotics, advanced instrumentation, enhanced visualisation, connectivity and data analytics”- aims to” democratise surgery” by bringing the percentage of robot-assisted surgeries from the present 5% up to 75%. In Britain, meanwhile, a 200 -strong company called Cambridge Medical Robotics is close to approval for its pioneering method, Versius, which it hopes to launch this year.

Wong says he accepts the event:” I tend to think it validates what we have been doing for two decades .”

The recent architects of robot surgeons view ways to move the technology into new areas. Martin Frost, CEO of the Cambridge company, tells me how the developing Versius has involved the input of hundreds of surgeons with various soft-tissue specialities, to create a portable and modular arrangement that could operate not only in pelvic spheres but in more impassable regions of the president, cervix and chest.

” Every operating theater in the world currently owns one essential element, which is the surgeons' limb and pas ,” Frost supposes.” We have taken all of the advantages of that structure to move something that is not only bio-mimicking but bio-enhancing .” The debate for the superiority of minimally invasive surgery is pretty much won, Frost hints:” The robotic genie is out of the bottle .”

And what about that next stage- does Frost view a future in which AI-driven procedures are involved in the operation itself?

” We see it in small steps ,” he articulates.” We think that it is possible, within a few years, that a robot may do part of certain procedures' itself ‘, but we are obviously a very long way from a machine doing diagnosis and panacea, and there being no human implied .”

The other holy grail of telesurgery- the possibility of remote “battlefield” enterprises- is closer to being a reality. In a celebrated instance, Dr Jacques Marescaux, a surgeon in Manhattan, exerted a protected high-speed communication and remote controls to successfully remove the gallbladder of a patient 3,800 miles away in Strasbourg in 2001. Since then there have been isolated instances of other remote enterprises but no regular programme.

In 2011, the US military funded a five-year study project to determine how workable such a programme might be with existing engineering. It was led by Dr Roger Smith at the Nicholson Center for advanced surgery in Florida.

Smith to present to me how his examine was primarily to determine two things: first, latency- the insignificant time lag of high-speed connects over big intervals- and second, how that lag interfered with a surgeon's moves. His studies found that if the slowdown rose above 250 milliseconds” the surgeon begins to see or sense that something is not quite right “. But also that using existing data bonds, between major municipalities, or at the least between major hospital structures,” the latency was always well below what a human surgeon could perceive “.

The problem lay in the risk of unreliability of the connection.” We all live on the internet ,” Smith pronounces.” Most of the time your internet bond is fantastic. Just occasionally information and data hinders to a slither. The questions is you don't know when that will happen. If it exists during a surgery you are in disturbance .” No surgeon- or patient- are looking forward to a buffering token on their screen.

The styles around that would involve dedicated systems- five strands of connectivity with a action level at least two times what you would ever hunger, Smith announces,” so that the chances of having an issue was exactly one in a million “.

Those kinds of connections are available, but the lack of investment is more one of regulation and drawback than expense. Who would bear the risk of acquaintance failure? The district in which the surgeon was located, or that in which individual patients was anaesthetised- or the two countries through which the cable guided? As a make, Smith replies:” In the civilian nature, there are few situations where you would say this is a must-have happening .”

He foresees three probable advocates of telesurgery: the military,” If you could, respond, create a contact where the surgeon could be in Italy and individual patients in Iraq “; medical preachers,” Where surgeons in the developed world driven through robots in places without advanced surgeons “; and Nasa,” At a part where you have enough people in space that you need to set up a route to do surgery .” For the time being the technology is not robust enough for any of these three.

For Jaime Wong health risks are likely to remain too great. Intuitive Surgical is engaging the concepts of “telementoring” or “teleproctoring” rather than telesurgery.” The neighbourhood surgeon would be performing the surgery, while our observe would be remote ,” he hints,” and a specialist mentor “couldve been” looking at different camera sentiments, providing second rulings. It will be like' telephone a sidekick ‘.”

True telesurgery, Roger Smith intimates, too begs a further question, one which we may yet hear in the coming decade or so.” Would you have an operation without a surgeon in the chamber ?” For the time being, the answer is still a no-brainer.
