Human livers "kept alive" by machine transplanted successfully for first time

By - March 18, 2013 5 Pictures
In a first for medical science, two livers have been successfully transplanted into patients following storage and transportation of the organs in a machine that keeps them warm and functioning. It's hoped that the machine, developed at the University of Oxford, could double the number of livers available for transplant at any given time, potentially saving thousands of lives every year.

Pressure-sensing surgical handle lights up like a real-life game of Operation

By - February 11, 2013 1 Picture
New technology may be ushering in the age of robotic surgery, but there is still a role for cutting-edge electronics to play in augmenting a surgeon's natural talents. The latest example of this comes from Germany, where researchers have proposed a way for doctors to operate using their own standard instruments by developing a special handle that fits on most surgical tools and lights up to indicate when enough pressure has been used during a procedure.

GE developing robotic system for hospitals

By - January 31, 2013 2 Pictures
Presently, when an operation is going to be performed at a hospital, people first locate all the instruments that the surgeon will require, inspect them, arrange them on a tray, sterilize them, and then deliver them to the operating room. According to General Electric’s GE Global Research division, however, robots could do all of those things better. To that end, the group has recently partnered with GE Healthcare and the U.S. Department of Veteran’s Affairs, in a US$2.5 million two-year project to develop just such robots. Read More

Sonic "invisible scalpel" could be used for non-invasive surgery

By - December 20, 2012 1 Picture
First of all, how can non-invasive surgery even be possible? After all, even in the case of minimally-invasive laparoscopic surgery, small incisions are still made in the skin. Nonetheless, that’s just what scientists from the University of Michigan are proposing. They believe that it could be achieved by using a beam of sound, which would be emitted through the skin to a highly-focused point within the body – and they’ve already created such a beam and used it.

DARPA foam fights internal bleeding

By - December 11, 2012 2 Pictures
The Defense Advanced Research Projects Agency (DARPA) is developing a foam that can be injected into the body cavities of battlefield wounded to protect them from internal abdominal bleeding. The agency hopes that when perfected, this polyurethane polymer foam will help the wounded to survive the critical minutes needed to transport them to proper surgical facilities for treatment.

SMART tool compensates for surgeons' hand tremors

By - September 28, 2012 1 Picture
No matter how steady you try to hold your hand, it will still tremble several times a second, moving a distance roughly the same as the thickness of a sheet of paper each time. While that might not matter much for the average person, it can be a very big deal to surgeons performing fine-scale surgery on things like eyes or nerve fibers. While there are experimental robotic devices to help smooth out the shakes, researchers from Johns Hopkins University have come up with something else – a surgical tool with a jiggling tip. Read More

HemoSep recovers blood during surgery to improve open-heart surgery prospects

By - September 6, 2012 1 Picture
A simpler, cheaper and more efficient method to recover blood lost during open heart and major trauma surgeries has been developed at the University of Strathclyde in Glasgow. Called HemoSep, the method has produced successful results during trials at the Kirikkale University Hospital in Ankara, Turkey, improving prospects for cardiac surgery patients. The technology is soon to be launched commercially. Read More

Student-designed surgical device could be the "future of suture"

By - August 20, 2012 2 Pictures
Just about every major operation on the chest or abdomen requires surgeons to cut through the fascia, which is a layer of muscle located immediately beneath the skin. Closing these wounds can be very difficult – sewing up an incision in the fascial layer has been likened to trying to push a needle through shoe leather. If proper care isn’t taken, however, potentially lethal complications can result. Now, a team of undergraduate students from Johns Hopkins University have created a device that should make the procedure easier and safer. Read More

Electronic fingertips could lead to smart surgical gloves

By - August 18, 2012 4 Pictures
Using industry-standard manufacturing technology, researchers have integrated ultrathin and stretchable silicon-based electronics, sensors and actuators on an artificial skin that can be worn on the tip of your fingers. The result is an artificial finger cuff that could be used to produce the ultimate hi-tech surgeon's glove, capable of sensing the electrical properties of tissue, removing it locally, or even performing ultrasound imaging with a simple touch.

Robot aids surgeons in catheter procedures, helps avoid radiation

By - July 28, 2012 3 Pictures
When we think about a heart operation, it’s only natural to be concerned about the risks faced by the patient. What is overlooked is that the surgeon often faces risks in the operating theater as well. All the modern surgical paraphernalia may make cardiac medicine tremendously more advanced than it was a generation ago, but some of that equipment uses radiation that can be very dangerous to be around ... and surgeons are around it a lot. To help alleviate this, Corindus Vascular Robotics of Natick, Massachusetts, developed the CorPath 200 System. It’s a robot-assisted catheter system for unblocking arteries that allows cardiac surgeons to operate from a protective lead-lined cockpit while carrying out cardiac stent and balloon procedures.
