Cambridge Robotics news

A nice article appeared recently, telling a little more about the daily business of Cambridge Robotics.
"Fast-growing tech firm Cambridge Medical Robotics isn't afraid to think big. Matthew Gooding went to meet chief executive Martin Frost and learn more about the company's modular robotic system that could transform surgery.
Describing a company's office as a pig-sty isn't usually the best way to make friends, but Cambridge Medical Robotics probably wouldn't take offence. "Our building is where they used to keep the pigs," explains chief executive Martin Frost, as we take a walk around the firm's premises at Crome Lea Business Park, a converted farm off Madingley Road which overlooks the rolling fields of south Cambridgeshire.
"When we got here it was just an empty shed with a concrete slab for a floor, so we've had to build it almost from the ground up. It's a brilliant space, though, and we love the view."
ARM famously started life in a Swaffham Bulbeck barn, so CMR is in good company. The firm, which was founded two years ago by Frost and a group of pals, is developing a modular robotic system which it believes can make minimal access surgery more, er, accessible to patients around the world.
"For surgeons, keyhole surgery is like trying to perform a difficult procedure using a knitting needle with a fine instrument attached to the end of it," says Martin, as he demonstrates one of these instruments, a terrifying-looking thing that's about a foot long. "You can only achieve movements of 180 degrees, and the process is very strenuous for the surgeon involved as they have to stand over a patient for hours at a time."
As someone who still bears the scars of having my gall bladder removed 18 months ago, it's enough to make me wince. But I should probably be grateful I live within hobbling distance of one of the country's most prestigious hospitals, otherwise those scars would be a lot larger.
"Obviously it's a lot better for you to have your gall bladder out using keyhole," Martin says. "But hospitals can't always find experienced keyhole surgeons, there might not be any in the area at all. There are 12 million procedures a year carried out which should be done by keyhole surgery, but only half of them are.
"Why use a robot? Well, it's more flexible and can be more precise and less invasive, meaning patients can recover quicker, have a shorter stay in hospital and health care providers can save money."
Surgical robots already exist, but their scope is limited, meaning they spend a lot of time gathering dust. CMR believes its system will be able to carry out 90 per cent of minimal access procedures, making it much more cost-effective.
Frost has form when it comes to device development, having spent 11 years with Sagentia, as CFO and CEO. His co-founders also worked at the Harston business, but he insists CMR is not a spin-out.
"We all share common DNA," he says. "Dr Mark Slack is chairman of our medical advisory board and head of pelvic reconstructive surgery at Addenbrooke's. He's a fantastic surgeon and would love to be able to use robotics as part of what he does, but he can't make the argument when the robot is expensive and won't be very busy.
"We want our system to be something that you can put in the hands of great surgeons and extend their capabilities.
"It's very different to everything else on the market. The control system is similar to that of a games console so it's much easier to learn and we think surgeons will be able to be trained on it in a matter of weeks."
Martin isn't keen to go into much other detail about the robot, with various patents pending (the company has already filed 50), but CMR has attracted plenty of interest from investors. It raised £4 million in seed funding in 2014, and earlier this year closed a £15 million Series A round. But more cash will be needed, lots more.
"When you're developing devices everything you do is big," says Martin. "We're a rare company in Cambridge in that we're actually making something, and realistically that means we need £35-£40 million.
"It can be a challenge because investors perceive devices as much riskier than biotech. I think it's because you have to build something then get it into the market before you get the return.
"We plan to double in size in the next 18 months, so we'll be up to 100 people by the end of 2017. That needs serious commitment and serious shareholders. It's a bit scary, but that's what you need to do to be successful with devices."
Indeed, speed is of the essence for CMR, not least because some industry big names are planning surgical robots of their own, with Google and Johnson & Johnson among those to have announced they plan to try to grab a slice of a worldwide market which is already worth $3 billion. The company has reported success in trials on human cadavers, and now plans to ramp up testing.
Dr Slack believes surgical robots will become a standard feature in operating theatres over the next decade, and Martin is confident CMR will be in prime position to take advantage of this growing trend. "Most predictions suggest the market for these robots will grow fivefold in the next decade," he says.
"The last revolution in surgery was when keyhole techniques were developed in the 1970s and 1980s, and beyond that you have to go back to the introduction of anaesthesia. Robotics has the potential to completely transform surgery, almost like when the first PCs were put into offices.
"I do believe we'll be ahead of the competition and be able to build a large market for our products. We want to be Cambridge's next billion dollar company, and we're not shy of saying it."

CRAS 2016 report

 Guest post by Renata Elek
This year, CRAS (Joint Workshop on New Technologies for Computer/Robot Assisted Surgery) was held in Pisa, Italy. The workshop “seeks to give a clear view on the status and recent trends of assistive surgical robotic technologies. It aims to support and propose concrete measures to accelerate research and innovation in this field. CRAS originates from efforts to collaborate among European groups to achieve a critical mass in surgical robotics. As such the workshop continue on discussions started at ERF in Lyon and at ICRA in Karlsruhe, and previous meetings at Verona and Genoa. More in particular CRAS attempts to identify the steps necessary to stimulate cooperation between research and industry, across national borders and different surgical robotic projects to take advantage of the growing attention and support for research and exploitation in this interesting and growing field”.
CRAS included:

  • 5 keynote speeches: the speakers were Paolo Dario from Scuola Superiore Sant'Anna,
  • Joel W. Burdick from California Institute of Technologies, Brian Davies from Imperial College London, Michel Brochard from European Commission, Franca Melfi from Robotic  Multispeciality  Center for Surgery, University Hospital of Pisa;
  • 7 sessions with the following topics: microsurgery, endoscopy, training, interfaces and tools, novel robotic hardware, sensing & classification, segmentation and algorithms, and safety and novel applications;
  • 3 poster sessions with various topics;
  • 3 special events: a COSUR event, a round table and the first European meeting of the DVRK community.

Our group submitted an extended abstract to CRAS: “Feature extraction-based automated camera motion for surgical endoscopy support”, which was accepted as poster presentation. See it below!  I had to make a poster teaser about our work and the poster was shown for one full day. CRAS will be held in Montpellier, France next year.
