Most medical equipment stock – you go to the closet and choose a catheter or implant and just stick to it, but what about situations where you need a teenager tiny socket for a premature baby or a special form. prepare? You refer to 3D-printing.

Researchers at Northwestern began creating custom plastic and ceramic implants, which are tuned to a particular patient. This means physicians can prevent injuries delicate fabrics and to prevent damage during the insertion or implantation of different devices.

“On neonatal care, every child is different sizes, each child has a different set of challenges,” said Randall Erb, associate professor of the Northeast. “You can print the catheter, the geometry of which is specific to the individual patient, it is possible to insert up to a certain critical point, you can avoid puncturing the vein, and you can accelerate the delivery of content.”

The researchers describe their technique in a recent paper.

The system uses both plastic and ceramic fibers to create a rigid and very precise things. Ceramic fibers in various configurations in an object to make holes and curves in the object more durable. According to the researchers, this is the same system used by “bone in the tree” to create a strong natural objects.

The command uses stereolithography and magnetism to control the position of the ceramic fiber and the place where it should flow. They magnetize the fiber in the first place – a process approved by the FDA – and then they are applied “ultra-low magnetic fields in some areas of composite materials, ceramic fibers immersed in liquid plastic-lined fiber in accordance with the specifications of the discerning dictated by the products they are printed.” It’s a smart way Paste durable materials into an object without actually extruding them.

The system is still in testing, but expect the results to find their way into your body sooner rather than later.
