Kryptonite provides five to ten times the mechanical strength of the breastbone closure of...

Stories about Kryptonite are sure to pique interest, and this one has both a "super" and a scientific angle. Canadian researchers are using a super glue called Kryptonite to create a stronger closure of the breastbone for heart patients after open chest surgery. This means faster recovery time, fewer complications and less post-operative pain.  Read More

The SpectroPen could help surgeons see the edges of tumors in human patients in real time ...

Statistics indicate that complete removal, or resection, of a tumor is the single most important predictor of patient survival for those with solid tumors. So, unsurprisingly, the first thing most patients want to know after surgery is whether the surgeon got everything. A new hand-held device called the SpectroPen could help surgeons provide a more definite and desirable answer by allowing them to see the edges of tumors in human patients in real time during surgery.  Read More

Robot-assisted surgery has a number of advantages over traditional surgery – it’s steadier, more precise, less invasive, plus the surgeon doesn’t even have to be in the same room (or continent) as the patient. One of its drawbacks, however, is the fact that surgeons can’t feel any of the resistance put up by the patients’ tissues – essentially, the controls provide no sense of touch. To address this problem, Linda van den Bedem from Eindhoven University of Technology (TU/e) has created a prototype surgical robot that does provide tactile feedback, and its name is Sofie... or Surgeon’s Operating Force-feedback Interface Eindhoven.  Read More

More than 1,000 tons (2.2 million pounds) of titanium devices are implanted in patients worldwide every year with joint replacements one of the more common procedures. Light, strong and totally biocompatible, titanium is one of the few materials that naturally match the requirements for implantation in the human body. Researchers have now developed an improved coating technique that could strengthen the connection between titanium joint-replacement implants with a patient’s own bone. The stronger connection – created by manipulating signals the body’s own cells use to encourage growth – could allow the implants to last longer.  Read More

Laparoscopic gastric banding is a common surgical treatment for morbid obesity and the most critical factor in the success of the operation lies in the hands of the surgeon - who needs the proficiency and skill to insert slender, handheld tools into the body of the patient. A team of interdisciplinary researchers, led by Rensselaer Polytechnic Institute, has recently won a US$2.3 million federal grant to develop a touch-sensitive virtual reality simulator that will realistically replicate how performing a gastric band operation feels - making it ideal for developing and teaching fundamental surgical skills and for assessing physicians wanting to be certified as a laparoscopic surgeon.  Read More

A robot guided by 3-D ultrasound and artificial intelligence has demonstrated it can locate lesions in simulated breast and prostate tissue and take biopsies without human assistance. A team of bioengineers at Duke University, North Carolina, 'souped up' an existing robot arm with a purpose-built ultrasound system which acts as the robot's 'eyes' by collecting data from its scan and locating its target. An artificial intelligence program processes the real-time 3D information from the ultrasound and gives the robot specific commands to perform using a mechanical 'hand' that can manipulate the same biopsy plunger device used by doctors.  Read More

It might be OK to see a trainee tag affixed to the chest of someone serving you a burger, but quite another to see the same tag on the chest of your surgeon as you’re put under before an operation. Of course that’s not the reality with trainee surgeons getting practice alongside more experienced surgeons and on cadavers. But cadavers don’t grow on trees – thankfully – and practicing on live patients exposes them to some risk. Now two Buffalo scientists have paired up to create a new procedure-based, hands-on surgical training software system that promises to deliver effective training in emerging robot-assisted surgical techniques.  Read More

The use of remotely-controlled robots to perform delicate surgery is growing. The approach offers benefits to both patients and doctors including reduced fatigue, quicker recovery times and a reduced risk of infection. Now another breakthrough in the field has been reported in the U.K., where doctors have performed a first in remote-controlled heart surgery.  Read More

Anesthetists cannot take their responsibilities lightly. Too little anesthetic and a patient may feel the whole procedure, too much and a patient might shuffle off this mortal coil. Researchers in the Canary Islands have taken the guesswork out of this thorny dilemma and developed a computer-controlled system that measures a patient's hypnotic state and applies the appropriate dose of anesthetic.  Read More

Natural platelets - seen here clumping from a blood smear - could soon get a helping hand ...

Blood clotting is a complex cascade of events that works well for normal cuts and scrapes, however, more serious injuries can overwhelm the body’s natural blood-clotting process. With traumatic injury the leading cause of death for people aged 4 to 44, a team of researchers has sought a way to enhance the natural blood-clotting process by creating synthetic platelets that show promise in halting internal and external bleeding.  Read More
