摘要：An apparatus (10) for determining the bending characteristics of a curvedsurgical needle (17) having a butt end portion and a tip portion (17a) including a basesupport (12), a clamp (15) for releasably gripping the butt end portion of the needle. A
system of stepper motors (24, 26, 28) and related plates (18, 20, 22) is provided formoving the gripped needle along a predetermined path. A load cell (16) is positionedwithin the predetermined path for engagement by the tip of the needle and for sensingthe forces generated by the moving needle tip, and a minimal friction support plate (14)is provided for the load cell to maintain the needle tip at a predetermined location onthe load cell while moving the gripped needle.
