A 3-D printer has created a 3D model of a child's trachea that could one day be used for tracheal surgery, the Seattle Times reports.
Seattle Children's Innovation Lab, which created the model with the help of a grant from the National Institutes of Health, says it's the first time a 3D model of a child's trachea has been used for tracheal surgery.
The trachea is a tube that runs from one end of a child's body to the other, and it needs to be strong enough to support the child's weight.
The model, which can be viewed here, shows how the child's windpipe would be attached to his or her body.
It also shows how the child's windpipe would be attached to his or her chest, which is needed for a successful surgery.
