BioPen pen supports bone regeneration
When the bone breaks down due to accident or surgery the limb, the tissues inside them are injured, it is difficult to transplant new implants with full function. To solve this problem, Australian scientists have developed a portable 3D printer named BioPen that is capable of regenerating new bone tissue.

The prototype BioPen looks like a pen, designed by experts at the University of Wollongong and recently clinically tested at St. Vincent's Hospital in Melbourne. It works like a 3D printer, which imprints layers of tissue and alginate into the injured bone before covering it with a protective gel.
These two materials are mixed together in the pen and surgeons can use the mixture to fill the injured bone. Next, the doctor will shine ultraviolet light so it dries out and they can create layers of cells called skeletons. The cells then multiply and bind to the cells of real bone tissue, including the muscles and nerves.
According to the researchers, Biopen will "allow surgeons to control where to print bone regeneration materials and to reduce the length of time the surgery takes patients by directing live cells to the affected site." It hurts, thereby promoting effective bone and cartilage regeneration. "
