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

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"

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

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

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.

"Desperate Debra" preps surgeons for tricky C-sections

Though its makers describe Desperate Debra as "the world's first impacted fetal head simulator," it's perhaps simpler to describe it as a practice dummy for caesarean sections carried out due to the baby's head having become wedged in the mother's pelvis: a situation known as impaction. It's a potentially life-threatening complication and one that is tricky to rectify. Manufacturer of medical simulators Adam,Rouilly has come up with Desperate Debra so that surgeons may practice the procedure. Read More

Nerve detour restores partial hand function in quadriplegic patient

It's been a good news week for those suffering debilitating spinal injuries. First we looked at a breakthrough that enables quadriplegic patients to move robotic arms using just their thoughts and now, in related news, surgeons at the Washington University School of Medicine have reported the successful rerouting of working nerves in the upper arms of a quadriplegic patient, restoring some hand function.

Prototype device could take a load off of obese patients during surgery

When an anesthetized obese patient is lying on their back on an operating table, the weight of their abdominal fat can make it difficult for them to breathe. It can also press down on and displace their organs, making certain procedures more challenging. Mehdi Razavi, director of electrophysiology clinical research at the Texas Heart Institute, had encountered such problems first-hand, with patients of his own. He decided to turn to Houston’s Rice University, to see if its students could come up with a solution. In response, a group of bioengineering seniors created something called the R-Aide, which uses vacuum-powered suction cups to lift up patients’ bellies. Read More

Femtosecond laser used in ultra-fast, ultra-accurate laser scalpel

The practice of surgically removing diseased or damaged tissue within the body is something of a trade-off – quite often, some of the surrounding healthy tissue will also end up being removed in the process. In highly-sensitive areas such as the brain or spinal cord, where a fraction of a millimeter either way can have huge consequences, sometimes surgery is deemed to be just too risky. A newly-developed endoscopic laser “scalpel,” however, looks like it could lower those risks considerably. Read More

Magnetically-controlled "growing rods" promise less surgery for children with scoliosis

Scoliosis is a lateral deformity of the spine, that most often shows up in young children and adolescents. Besides resulting in disfigurement, in some cases it can also cause breathing problems. In severe cases, if the child is still growing, telescoping steel rods are surgically implanted alongside the deformed section of the spine, in order to straighten it. Unfortunately, repeat surgeries are necessary every six months, in order to lengthen the rods as the child grows. Now, however, scientists from the University of Hong Kong are reporting success in the first human trials of a system that incorporates rods which can be lengthened using magnets instead of surgery.
