Abstract
A driver apparatus for implanting spinal rod fixation devices including an anchor member and a coupling member pivotable relative to the anchor member is disclosed. The driver apparatus generally immobilizes the anchor member and coupling member relative to each other and to the driver apparatus during insertion to minimize interference between the coupling member and tissues surrounding the implantation site, as well as to minimize the clearance required for implantation. The driver apparatus includes a driver portion engageable with the anchor member for effecting seating of the anchor member, such as by threadably driving the anchor member in the bone. The driver portion is closely fit between portions such as upstanding walls of the coupling member to prevent relative rotation therebetween. The driver apparatus further includes locking portions shiftable to secure the coupling member with the driver apparatus when the driver is engaged with the anchor member.
