Most guns are tools for doing harm, but a team of American and Korean scientists has developed one that does the opposite, helping to patch up bone injuries. It comes a bit short of the Medigun from Team Fortress 2 or Ana’s Biotic Rifle, which featured in Overwatch. But it’s probably one of the first shots we have at making healing guns real.
3D printing on the fly
In more complex bone problems like severe, irregular fractures or resections done as part of bone cancer treatment, the bone won’t heal on its own. The most common means of stabilizing the injured site and making recovery possible is metal-based grafts, implants usually made with titanium alloys.
The problem with such implants is that they are difficult and expensive to manufacture, and it’s very hard to make them patient-specific. “3D printing has been highlighted as a novel approach to make such personalized implants, but this also requires substantial time and money,” said Jung Seung Lee, a biomedical engineering researcher at the Sungkyunkwan University in Korea. So his team wanted to find a way to make bone implants that would be faster and cheaper than a 3D printer.
