The standard inkjet printer found in offices around the world is the inspiration for a new medical device that can help patients with severe burns. Researchers at Wake Forest University rigged up a device that can spray skin cells directly onto a burn victim's wounds, and animal trials showed that the treatment healed wounds quickly and safely. The team says this printing method could be an improvement over traditional skin grafts, which often leave serious scars. The researchers explain that the device is mounted in a frame that can be wheeled over a patient in a hospital bed. A laser then takes a reading of the wound's size and shape so that a layer of healing cells can be precisely applied, Reuters reports.
"We literally print the cells directly onto the wound," said student Kyle Binder, who helped design the device. "We can put specific cells where they need to ...
