Innovative revolving biopsy device design supported by additive manufacturing

Abstract

Additive manufacturing is widely used in the meantime for medical device developments. Specially the BioDesign process with strong user integration and feedback loops benefits from fast prototyping. In this work, an innovative conceptual design of revolving biopsy needle is CAD modelled using SolidWorks software and subsequently 3D printed. The material properties of the resins were fit to use for fabrication of the different mechanisms that the prototype requires. 3D printing is a very good method of quickly checking different design ideas, to present functionalities to clinical partners, to optimize and define the ideal design. Even delicate structures are possible.
