Abstract
A surgical tool includes a proximal end, a distal end and a longitudinal axis extending from the proximal end to the distal end. The surgical tool has a fastener engagement tip having a spring extension extending substantially parallel to the longitudinal axis of the surgical tool. The spring extension is resiliently flexible and deflectable between a first arrangement, in which the spring extension is in a relaxed state, and a second arrangement, in which the spring extension is deflected to facilitate insertion of the fastener engagement tip into a fastener slot.
Claims16
A surgical tool for driving a fastener into bone, the surgical tool comprising a proximal end, a distal end and a longitudinal axis extending from the proximal end to the distal end, the surgical tool comprising a fastener engagement tip having at least two extensions for insertion into a slot in a head of a fastener, the at least two extensions extending substantially parallel to one another in a direction substantially parallel to the longitudinal axis of the surgical tool, at least one of the at least two extensions being resiliently flexible and deflectable between a first arrangement, in which it is in a relaxed state, and a second arrangement, in which it is deflected toward the other of the at least two extensions, the at least two extensions compressed together in the second arrangement so that the at least two extensions fit inside a slot in a head of a fastener, the fastener engagement tip forming a Philips head screw driver tip having four blades, with at least one of the four blades comprising the at least two extensions.
