European scientists developing new Augmented Reality visor to improve accuracy of surgical interventions

Posted on Updated on

imageEmploying new photonics technology, European scientists are developing a new Augmented Reality surgical visor in a bid to improve accuracy of interventions, showing anaesthetic and medical data while superimposing a patient’s x-ray in perfect unison with their body, meaning surgeons never having to look away during an operation and surgery times reduced by over 20 minutes for every 3 hours.

The VOSTARS (‘Video Optical See-Through Augmented Reality surgical System’) medical visor is a head-mounted display (HMD) system that is capable of superimposing the patient’s x-ray images in perfect 3D unison with their anatomy.

The visor also presents a patient’s anaesthetic data, heart rate, body temperature, blood pressure, and breathing rates, conveniently into the surgeon’s field of vision, in a drive to increase accuracy by focusing on the operation and reduce time by never having to look away.

Here’s What Convinced a Heart Surgeon to Use 3D Printing

Posted on

C6a-4YPWQAAYg6KDr. Sloane Guy thought 3D printing models was just a gimmick, until he held one in his hands.

When I walked into Dr. Sloane Guy’s office Tuesday morning, he and a cardiac surgery nurse practitioner were surveying a detailed 3D image on his computer screen. It was a CT scan of a patient’s heart. As Guy, an open heart surgeon, manipulated the image on the screen he and Amber Lennon, the nurse practitioner, discussed whether the patient would be a good candidate for robotic surgery, Guy’s specialty. The other option would be the old-fashioned way, which would require a sternotomy, colloquially known as “cracking open the ribcage.” They opted for the latter.

“We’ll just have to let him know that this is the reason we do these studies, to look for things that may make him non ideal [for robotic surgery],” said Guy, who’s also an associate professor at Weill Cornell Medicine in New York. “There’s nothing wrong with a sternotomy. What’s important is that we get him through surgery safely.”

Queens teen sings again after Mt. Sinai doctors remove rare golf ball-sized tumor

Posted on Updated on

surgery16n-3-webA Queens teen’s hope of singing are back thanks to an innovative brain surgery. Galahad Abella, 17, became worried when he began to see double the day after Christmas. A CT scan revealed that he had a rare golf ball-sized tumor. The tumor, called Clival Chordoma, is mainly found in patients aged 20-40. The teen from Elmhurst, Queens dreams of becoming a professional opera singer and has already performed at Carnegie Hall. Thankfully, his medical team at Mt. Sinai Hospital was able to remove the tumor, after breaking it up into pieces, through his nose. During the surgery, Dr. Anthony Del Signore used a virtual reality like technique called “Surgical Theater” which captures a 3D image of the skull and tumor.

Doctors Gave This Man a New Face

Posted on

transplant1In 2006, a 21-year old Andy Sandness unsuccessfully attempted suicide. He had aimed a bullet at his chin, which ended up destroying the lower half of his face. He was rushed to Mayo Clinic in Rochester, Minnesota where doctors finally stabilized him, but nothing could be done about his missing jaw, teeth, and nose.

Sandness went back to his home and job in Wyoming, but six years later, the Mayo Clinic delivered some hopeful news. In 2012, the hospital proposed the idea of a face transplant, a procedure with many risks and possible complications following the final surgery. But, Sandness accepted the dangers, staying hopeful, and agreed to the operation.

How 3D printing could revolutionise surgery

Posted on

p04qz7y1Several years ago Edward Evans fell seriously ill when an infection began eating away at his sternum – the bone at the centre of the ribcage that protects the vital organs in the chest. Medication failed to eradicate the problem, so Edward had to undergo surgery to have the infected sternum and parts of his adjacent ribs removed.

At the time, it was impossible for the surgeons to do anything more than cover the resulting defect with Edward’s own muscle, because putting any foreign object into his chest when infection was rampant would almost certainly have resulted in that foreign material also becoming infected.

Edward recovered well from this surgery, but the absence of a solid sternum meant that his heart and lungs were extremely vulnerable, and his quality of life was limited. So doctors at Heartlands Hospital in Birmingham arranged for Edward to undergo another operation to have a new sternum implanted.

Virtual Reality Can Make the Pain of Surgery Easier to Bear

c3kk28lwqaathvcAna Maria has never been to Machu Picchu. The 61-year-old always wanted to visit the mountain ruins but she suffers from hypertension, and doctors warned that the extreme altitude could cause her blood pressure to rise dangerously high. Today, dressed in a white gown and hairnet, she will explore its ancient walls and pyramids for the first time.

She’s in a private medical clinic in Mexico City, and laughs nervously as she’s wheeled into a windowless operating room. The surgeon takes a Sharpie and draws a large circle on her left thigh, paints on several layers of iodine, then injects a local anesthetic into the skin. Inside the circle is a fatty lump, a lipoma around six centimeters across, which he is about to remove.

Philips Announces New Augmented Reality Spine Surgery Navigation Tech

Posted on

philips-surgical-navigation-technology-based-on-augmented-reality-2Philips today announced a rather interesting new breakthrough navigation technology meant for minimally invasive spine surgery for use in their “hybrid ORs.” The ORs themselves are specialized for procedures like spine surgery and contain an integrated fluoroscopy unit with 3D reconstructions like that seen in technologies like the O-arm.

The new navigation technology combines an optical tracking system with the CT-like functionality of the fluoro unit. This provides 3-dimensional navigation functionality much like that seen in Medtronic‘s Stealth station or Brainlab‘s large library of products.

The specific feature Philips is promoting is its “augmented reality” functionality. There are additional cameras attached to the fluoroscopy unit that combine images of the patient’s anatomy with the 3-dimensional imaging, outputting the result on a high resolution monitor. This theoretically gives the surgeon a better idea of where in the patient’s anatomy he should be initiating his pedicle screw placement while also taking advantage of the 3D navigation to ensure screw accuracy through the pedicle.
