The future of medical robotics

There is a quiet robotic revolution occurring in the health sector that will prove crucial in an age of austerity, ageing and expanding populations, and medical staff shortages.

With its once sky-high cost, the economics of advanced medical technology did not allow for any fast integration into our cash-strapped public hospitals or even the better-off private institutions.

But with gradually-declining running costs and healthcare leaders searching for new means of efficiency, we can expect to see more and more robotic systems in our hospitals.

In fact, if you experience surgery in the future, chances are that your surgeon will be accompanied by a robotic assistant. With pinpoint precision, remarkable Artificial Intelligence (A.I.) and advanced algorithms, the presence of a robot will make your operation safer, faster and more hygienic.

By providing surgical and other assistance to hospitals, medical robotics are already bringing down the cost of healthcare, eliminating human error, streamlining operating theatres, reducing operating time, and, crucially, freeing-up staff for more pressing matters.

However, the uptake of such technology must be accelerated.

Should current trends continue, the global needs-based shortage of health-care workers is projected to be still more than 14 million in 2030, according to World Health Organization estimates.

But thought leaders like Dr. Bertalan Mesko, PhD, founder of the Medical Futurist website believe that technology will be the key to such challenges. Mesko predicts that methods of automation – such as A.I. robotics and 3D printing – will help to make healthcare sustainable and much more efficient in the future.

In England alone, recent research showed that NHS hospitals could undertake 17 per cent (280,000) more non-emergency operating procedures every year with better-organised operating theatre schedules.

The research, which analysed 2016 data collected from operating theatres in 100 NHS Trusts in England revealed that more than two hours a day are wasted on average.

This suggests that operating theatres are significantly underutilised, with each procedure becoming costlier as a result.

Such under performance can be devastating in rocky periods. Leading medics recently warned that thousands of NHS operations could be cancelled for months this winter due to bed and staff shortages.

So how fast will the medical sector embrace these technologies? And, what might they look like?

Mechanical medical assistants, of course, do already exist, and in many different incarnations. For example, UWE Bristol researchers in the University of Bristol’s Robotics Laboratory (BRL) are creating new robotic tools and devices to be used semi-automatically under the supervision of surgeons during invasive medical procedures.

BRL’s Dr Sanja Dogramadzi, who researches the use of robotic technologies to repair complex joint fractures, believes these tools have the potential to aid orthopaedic, abdominal and cardiovascular surgery. “By using minimally invasive access to organs and tissues, robotic tools can help to reduce trauma, speed up recovery and minimise costs.” she said.

In her field, small robotic tools can be used to perform closed-joint reduction “with minimal invasion”. This alternative to the current open-joint surgery used to treat these types of fractures avoids the increased risk of infections and tissue failures, which can be a major risk with such invasive surgery.

On a larger scale, Google is now working with Johnson and Johnson’s medical device company, Ethicon to develop A.I. surgical robots to assist surgeons during invasive operations. The tech giant, which will provide the software, believes it can use the machine vision and image analysis it has developed for self-driving cars and other ventures.
