Abstract

See full text

A threaded fastener driving tool includes a proximal end portion, a distal driving head, and a torsion zone extending proximally from the driving head, The distal driving head has a central portion and a plurality of driving surfaces. Each pair of adjacent driving surfaces define a driving space therebetween. The driving surfaces and driving spaces are configured to engage a threaded fastener. The torsion zone includes a plurality of helical grooves bounded by non-cutting surfaces, each helical groove in communication with and extending proximally from at least one of the driving spaces. The helical grooves are configured to untwist and cause lengthening of the torsion zone when an input torque applied to the proximal end portion is insufficient to overcome an output resistance torque at the driving head. The torsion zone may comprise a plurality of twisted wires or cables. A method of manufacturing the driving tool is disclosed.
