Portable 3D-printer will help the skin to "patch" the deep wounds
Scientists from the University of Toronto have developed a portable 3D printer-skin, which helps in the treatment of deep wounds. This is the first device capable of creating tissue to deposit and set in place for two minutes or less. A study conducted by the student Navid Hakimi headed by Associate Professor Axel Guenther, was published in Lab on a Chip journal.
when the image is a deep wound in the skin can be damaged by all three layers of skin - the epidermis, dermis and hypodermis. Currently, the preferred treatment is to take epidermopilyarnogo flap skin transplantation as part of a healthy donor skin grafted onto the surface of the epidermis and the underlying dermis.
Skin grafting for large wounds require a sufficient number of healthy donor skin to cover all three layers, so it is rarely possible to carry out on the spot. Most of the surface of the wound is "uncovered", leading to not be the best outcome.
Although there are quite a lot of leather substitutes, they are still not as widely used in the clinical setting. via GIPHY
"Most modern 3D-bioprinter cumbersome work at low speed, expensive and incompatible with clinical application," Guenther explains.
The scientists believe that their printer - it is a platform, able to overcome these barriers, improve the skin's healing process. Pocket printer skin similar to a toilet paper dispenser - but instead it microdevice roll forming fabric sheets. Vertical stripes "biochernil" consisting of protein biomaterials such as collagen and fibrin, in aggregate form each skin plate. The printer is very portable and promises to adapt to the specific characteristics of each patient and the wound.
A small device the size of a shoebox and weighs less than one kilogram requires minimal operator skills. Scientists hope that one day will be able to begin clinical trials in humans and fundamentally turn the traditional approach to the treatment of burns.
