Abstract
The invention relates to a device for attaching fixation elements to bone, having a longitudinal member with a channel extending therein adapted for receiving at least one fixation element. A shaft extends within the channel and is positioned coaxially within at least a portion of the longitudinal member and at least a portion of the shaft is retained within the longitudinal member and a distal end of the shaft is configured and adapted to contact at least a portion of the fixation element received within the longitudinal member. A spring is positioned adjacent the shaft for resiliently biasing the shaft in an axial direction and the shaft is moveable with respect to the longitudinal member to drive the fixation element into bone.
