Govt to aid in creation of robot surgery
Posted on AARS: June 29, 2014
The Japanese government will team with leading manufacturers and universities on joint development of a robot-assisted operating theater, aiming for its practical use within 10 years.
A domestic team comprised of leading manufacturers, including Hitachi, Ltd., Panasonic Corp. and Toshiba Corp., and five universities will vie for a leading position in the global medical equipment race with the United States, where robotic technologies are already being used in the field.
The planned technologies in the robot-assisted operating theater will enable doctors to perform operations with precision and simultaneously check magnetic resonance imaging (MRI) readings to monitor the condition of patients.
Developers aim to have robot arms, which can move with far greater accuracy than human hands, be interconnected with MRIs and other devices, enabling them to exchange related data.
MRIs are generally used in pre-operative examinations. In a robot-assisted operating theater, however, doctors can perform operations while using MRIs to examine such details as the spread of tumors, allowing for a more accurate examination of whether a cancer has been completely removed.
Having a device that can quickly ascertain the malignancy of tumors will also help doctors decide whether they need to be removed. By examining affected areas in tandem with test results shown on the monitor in the envisaged room, surgeons can carry out operations while keeping abreast of the condition of patients’ constantly changing conditions.
Five universities and 14 companies are to take part in the joint development, including Hitachi, a Toshiba-affiliated medical equipment maker and Tokyo Women’s Medical University.......continue reading
Prostate Cancer Radiation: What You Need to Know About Secondary Cancers
June 27, 2014
Important new findings about prostate cancer treatment highlight the increased risk of secondary cancers after radiation therapy. In a recently published study, researchers reported that men who underwent external beam radiation therapy increased their long-term risk of developing rectal cancer by 70 percent and bladder cancer by 40 percent versus the general population. External beam radiation therapy (EBRT) and robotic prostate surgery are leading treatment options for men with prostate cancer.
As in many other prostate cancer studies, researchers reviewed data from the Surveillance, Epidemiology, and End Results (SEER) program of population-based cancer registries. This particular study included data from more than 440,000 men who were diagnosed with prostate cancer between 1992 and 2010.
Interestingly, the study found that men with prostate cancer were less likely than the general population to develop secondary cancers overall. However, those that had EBRT were significantly more likely to be diagnosed with bladder or rectal cancer 10 years or more after their prostate cancer diagnosis......read complete article
From knife, to needle, to nothing at all, ultrasound offers the potential for completely bloodless surgery
From knife, to needle, to nothing at all, ultrasound offers the potential for completely bloodless surgery.
June 25, 2014
The patient, ready to have a malignant breast tumour removed, lies face down on a special operating table with a controlled integrated container of water. The water is the medium through which the surgery will be conducted.
Through an opening in the operating table, the affected breast, inside a latex shield, is suspended in the water. An instrument array comprising multiple robotically operated ultrasound transducers fires up under the guidance of the surgeon.
Using previously determined coordinates, the array precisely targets the cancer deep within the breast tissue. Within seconds the soundwaves travel through the water, unimpaired by air (which disperses sound) and converge, converting their energy to heat that sears away the cancerous tissue. The ultrasound transducers repeatedly refocus and refire, as directed, until all of the identified cancer tissue has been burned away.
These ultrasound waves are tightly focused so that no surrounding tissue is damaged. There are no cuts, no wounds to heal, no blood loss and no extended hospital stay.
This scenario, while not yet an actual clinical practice, is a realistic glimpse into the future of surgery being designed by Monash University systems engineer Professor Sunita Chauhan, a specialist in medical robotics......read more

Q&A: Surgeon, inventor Catherine Mohr pushes robotic surgery to new heights
June 13, 2014
She calls herself "a tinkerer at heart."
And ever since Catherine Mohr walked into a Boston-area bike shop looking for a high school job repairing drive trains and spokes, the New Zealand-born surgeon and inventor has taken tinkering to a mind-boggling high art here in Silicon Valley.
As director of research at Sunnyvale-based Intuitive Surgical, makers of a surgical robot called da Vinci, Mohr bridges the fields of medicine and technology as she tries to build upon the already amazing advances in robotic surgery. Like other new and disruptive technologies, the practice of surgeons remotely using robotic "surrogate" hands instead of their own to perform operations has generated controversy in some parts of the medical community. A spate of litigation and questions about cost-effectiveness have partially deflated Intuitive's stock price in the past year, but the company recently introduced its newest version of the da Vinci and plans to expand into new surgical areas.
Researchers Craft Surgical Tools Inspired by Octopus Tentacles
June 12, 2014
The octopus has captured human imagination for centuries. “To believe in the octopus, one must have seen it,” wrote Victor Hugo in 1866. “Compared with it, the hydras of old are laughable.” Today, the dance-like movements of the octopus serve as the muse for engineers of an innovative new project called STIFF-FLOP.
The project’s goal is to create a robotic surgical arm that will navigate the human body with the same grace that octopods use to navigate the ocean.
A team of researchers at Hebrew University of Jerusalem has recently solved an octopus enigma no one had previously tackled: How does the octopus keep its eight arms from sticking together or becoming entangled?
It turns out that chemical recognition is responsible for the tentacles’ selective sticking abilities. When an octopus’ suckers come in contact with its own skin, a chemical message is sent to momentarily stop them from working. “We were kind of amazed that this…was the answer,” explains Guy Levy, a researcher with the study. “We had to repeat it many times to convince ourselves that it was true.”
The new findings were received with enthusiasm by coordinators from the European Commission’s STIFF-FLOP project (STIFFness controllable Flexible and Learn-able manipulator for surgical OPerations). According to Kaspar Althoefer, a STIFF-FLOP project coordinator, the findings at Hebrew U. could help lead to a “biologically inspired solution to keep the tentacle-like robots apart while the tentacle tips are coordinated in their actions to perform an operation.".....read more

The Department of Defense has extended its grant funding to the Florida Hospital Nicholson Center for robotic surgery research.
DoD extends Fla. Hospital robotic surgery research grant funding
June 10, 2014
Florida Hospital Nicholson Center’s three-year research into remote surgery, also known as telesurgery, was funded with a $4.2 million Department of Defense grant to answer two questions: “Can it be done?” and “Is it safe?”
The center announced the results today: Yes.
In fact, the Department of Defense has chosen to extend the Nicholson Center’s funding to continue its robotic surgery research.
As part of the research done during the past three years, Roger Smith, chief technology officer at the Florida Hospital Nicholson Center, asked doctors to try telesurgery using a robotic surgery simulator developed by Mimic Technologies Inc. In a telesurgery environment, there's a communications delay between a surgeon in one location performing an operation and the patient in another location across the city, state or country.
The team researched how this delay would affect the surgeons during an operation, and determined that a 200 milliseconds delay (almost the speed of a blink) was imperceptible to surgeons and most of them could compensate for delays up to 500 milliseconds (half a second)......read more

Tiny £10m Robot Hand to Perform Surgery on Unborn Babies
June 1, 2014
A minuscule device is under development to provide 3D images of a foetus while it is still in the womb and act as an automated robotic hand.
Researchers are working on a £10 million project to create a tiny surgical robot hand that could transform treatment for children with spina bifida and other congenital conditions. It could also carry out surgery or deliver stem cells to an unborn infant's damaged organs.
The £10m research project is being carried out by engineers at University College London and KU Leuven in Belgium.
"The aim is to create less invasive surgical technologies to treat a wide range of diseases in the womb, with considerably less risk to both mother and baby," the project leader, Professor Sebastien Ourselin of the UCL centre for medical image computing, told the Observer.
The Wellcome-funded project is aimed at developing instruments based on the latest optics and robotics. A very thin, highly flexible probe would be inserted into the womb of a woman carrying a child with spina bifida......read more
