Abstract
A surgical staple extractor which has a gripping portion and a pair spaced-apart jaws and an anvil associated with the gripping portion. Structures are provided with the gripping portion for moving the anvil and the jaws in a scissor action to transfer forces from the anvil and jaws to a staple retained therebetween in order to mechanically deform or reform the staple for extraction from a patient. Cams are positioned between the jaws and the anvil for positively camming or displacing the jaws outwardly when the anvil jaws and jaws are operated. Actuation of the gripping portion results in moving the anvil and jaws with the cams interacting between the anvil and jaws for positively displacing the jaws outwardly in relation to the anvil for promoting controlled deformation of the staple in a removal path approximating the entry path thereby disengaging the staple from the patient.
