An Example of 3-D Printing for Expeditionary Medicine: The Air Force Retractor.

Introduction: Future challenges for the U.S. Department of Defense (DoD) include operating in a contested environment against near-peer adversaries. Providing casualty care in an anti-access/area denial (A2/AD) region would be potentially challenged by impaired logistical ability to reconstitute supplies or adapt to evolving needs. Additive manufacturing (AM), also known as 3D printing, offers an ability to regenerate stocked items as well as modify them or even create novel products de novo.
Materials and Methods: This article discusses relevant technology and applications for deployed medical forces. Additionally, as proof of concept, we outline our design process for a novel 3D-printed surgical retractor.
Results: Our "Air Force Retractor" prototype highlights the potential of using AM to create or augment surgical instruments downrange.
Conclusions: This paper encourages further investigation of the use of AM/3D printing downrange to create surgical instruments and medical supplies in austere, A2/AD, and other logistically challenging environments. Not only would this support regeneration of supplies, but also modification and even creation of novel products to adapt to changing needs. If 3D files could be created of common surgical instruments for print on designated resins downrange, and FDA approval obtained, an online library of files could be created for easy access to DoD members across the globe to support our nation's commitment to provide the best possible care for service members any time, any place.
