3D printed windpipe improves girl's operation

A 3D-printed windpipe has been used to practise delicate surgery before an operation on a six-year-old girl at London's Great Ormond Street Hospital.



It meant doctors could pick the correct tools needed to wash her lungs.

And as a result, Katie Parke, from Northern Ireland, needed to spend less time under anaesthetic and being ventilated.

Doctors at the hospital say the technology could also be used to train other doctors.

Katie has pulmonary alveolar proteinosis, which means grainy deposits build up in the microscopic air sacs in her lungs making it hard to breathe.

Regularly washing the lungs with saltwater is the only way to remove the deposits.

During Katie's operation one of her lungs needed to be ventilated while the other was cleaned.

Normally, surgeons waste time on the operating table trying multiple combinations of different-sized tubes in order to perform the delicate surgery.

The team at Great Ormond Street Hospital used a CT scan of Katie to print out a 3D rubber model of Katie's trachea. They could then select the tools they needed ahead of the operation.

Katie's mum, Sharon Parke, said: "It's amazing to see what a tiny bit of kit can do. Katie's had brilliant treatment at Great Ormond Street and now she can even go horseriding, which was unthinkable before."

Owen Arthurs, a consultant radiologist who organised the study said: "We can look at a 3D reconstruction on a computer, but this takes it into a whole new dimension.

"Being able to hold it in your hand makes the procedure much easier and safer."

Doctors at Boston Children's Hospital, in the US, have also tried printing models of part of the brain ahead of surgery.

Dr Arthurs added: "It could also be used to make training better, being able to print a part of the anatomy is quite powerful. It's really important to train the next generation of doctors and make them better."

Commodore Ute to US: 100,000 votes needed!

According to The Age Drive and an article by Barry Park, we are again set to export our Commodore Ute to the US.

The article is as follows:

US website rallies to GM's Twitter call of 'If you ask for an El Camino ute, we'll do it'.

An off-the-cuff quip from General Motors' newly appointed chief marketing officer could be just the thing to help Holden's cause to sell the Commodore ute in the US.

Joel Ewanick, who made the jump from Hyundai to the US car maker late last year, recently joined the social networking service Twitter. He soon started interacting with Chevrolet fans, with many of them asking for the car maker to re-introduce a vehicle based on a cross between a truck (ute) and a car.

In response to one passionate request for a new-age El Camino, Ewanick wrote: ''Well, we need you and 100,000 more of your best friends.''

Canberra para-athlete Scott Reardon wins gold with 3D Printed Spike Plates

Canberra para-athlete Scott Reardon has sprinted his way to gold at the IPC Athletics World Championships in Doha with victory in the T42 100m for leg amputees.

The fastest qualifier coming into the finals, Reardon, using a 3D Printed Spike Plate, got his nose in front to stop the clock in a time of 12.13 seconds - a mere one-hundredth of a second in front of Russia's Anton Prokhorov.
It was sweet revenge for Reardon, the 25-year-old having to share the gold medal two years ago at the world championships in Lyon in 2013 with Germany's Heinrich Popow​.
"You come to championships to win championships and that's the most important thing," Reardon said.
"I probably didn't get the time I wanted, but when people look back, how I got there won't matter. "It will just show me as world champion, and that's so exciting."
The result is the culmination of more than a decade of determination and training.

The Spike Plates which Reardon used in the …
