Abstract: A plurality of the elongated grippers are mounted in spaced apart, axially parallel, relation to project perpendicularly from opposing, substantially semi-circular, jaws of a pair of blades pivoted at a midportion thereof in scissor-fashion. A pair of lever arms are pivotally connected at one end and have handle portions formed at opposite ends thereof, said blades being symmetrically mounted between said lever arms with one end of each of the blades opposite said jaws pivotally attached to one of the lever arms for actuation thereby and for providing a mechanical advantage to close the jaws on application of a manual force applied to the handle portions. This closing brings the grippers of each jaw toward each other providing a compressive force on a breast requiring closed compression rupture when positioned therebetween.
