Doctors printed on 3D-printer trachea suitable for human implantation

Scientists from the Medical Research Institute Feinstein used modified 3D-printer MakerBot to print human cartilage in order to eliminate Damage in the trachea. Scientists printed frame of polylactic acid and collagen cartilage cells. The cells survived and formed a printing process suitable for transplantation trachea.





Tracheal injury can be caused by cancer, other diseases or trauma. Restore the trachea in two ways: pull the damaged segments to each other and sew them, or take cartilage from another part of the body to compensate for the missing tissue. On словам one of the doctors every year in North Shore-LIJ Health System comes at least one patient who does not fit into any one of these methods of treatment. The researchers decided to find a third solution, which used an experimental 3D-printer MakerBot Replicator 2X.

The printer can print frame polylactic acid biopolymer used in surgical implants. The team modified the printer to print over the carcass living cells. A mixture of healthy cartilage cells and collagen taken the form of the trachea, which can be implanted patient. The cells survived the printing process and have continued to grow, both in the human body.

3D-press used in medicine to create bones, including the vertebrae, scapula, hip bone of the skull. Doctors use 3D-models of their patients to prepare for operations, sometimes this method allows preserve vision or even human life, as it was with twelve year old girl, survived the removal of an inoperable tumor.
