Abstract
An apparatus and method is disclosed for determining the bending strength of curved surgical needles. The apparatus includes a means to releasably grip the butt end portion of the needle connected to a rotatable flywheel. A knife edge is positioned in the path of the rotating needle and engaged thereby, while a load cell to which the knife edge is connected, generates signals in dependence upon the bending movements applied to the needle. Such signals are transmitted to appropriate monitoring and recording instrumentation. The rotation of the needle with respect to a center of rotation and with respect to the knife edge are maintained to within precise limitations.
