ABSTRACT:
An apparatus for determining the bending characteristics of a curved surgical needle having a butt end portion and a tip portion including a base support, a clamp for releasably gripping the butt end portion of the needle. A system of stepper motors and related plates is provided for moving the gripped needle along a predetermined path. A load cell is positioned within the predetermined path for engagement by the tip of the needle and for sensing the forces generated by the moving needle tip, and a minimal friction support plate is provided for the load cell to maintain the needle tip at a predetermined location on the load cell while moving the gripped needle.
