Abstract
A manually actuated surgical staple extractor comprising upper and lower handles pivotally joined together and swingable between open and closed positions. The upper handle terminates at its forward end in a pair of thin, flat, laterally extending stops separated by a blade-receiving slot. The forwardmost portions of the stops lie in an obtuse angle to the upper handle and are joined together by a thin, coplanar, forwardly projecting, U-shaped anvil. The lower handle terminates in a thin blade. When the handles are in their open positions, the blade is located in the above noted slot with its lower edge above the anvil. When the handles are shifted toward each other to their closed positions, the blade pivots downwardly so that it passes through the U-shaped anvil to a position therebelow. The blade and the anvil are so configured that, as the blade passes through the anvil, there is clearance therebetween to either side of the blade, the clearance being at least equal to the diameter of the crown portion of the staple.
