Abstract:
A tool set for implanting bone screws in a human spine, followed by the implantation of a rod into the bone screws includes end guide tools having flexible back wall flaps that receive opposite ends of the rod and intermediate guide tools that hold the rod in intermediate locations between the end guide tools. Both the end and intermediate guide tools include an attachment structure for operably connecting the guide tool to a bone screw. The attachment structure includes an undercut and/or recess so as to resist splaying and separation of the guide tool from an attached bone screw.

Claim (Index 1):
A pivotal bone anchor assembly for securing an elongate rod to a bone, the bone anchor assembly comprising:\n a receiver having a longitudinal axis, a base, and a pair of upstanding arms extending upwardly from the base with opposed inner surfaces defining an open channel for receiving the elongate rod, the arm inner surfaces having a closure top mating feature formed thereon, the base including a cavity in communication with the open channel and with a bottom surface of the base through a bottom opening to define a receiver bore centered about the longitudinal axis, the cavity having a lower seating region defined by a curvate seating surface proximate the bottom opening and an upper capture region, the receiver including an inwardly sloping and protruding rigid structure machined into interior surfaces of the bore below the closure top mating feature and having an underside surface defining a ceiling surface of the upper capture region; and a bone anchor having an upper portion and an integral lower portion extending distally from the upper portion for fixation to the bone, the upper portion being disposed within the receiver cavity with the lower portion extending downwardly through the bottom opening, the upper portion having an at least partial spherical top surface having a first diameter, an at least partially spherical lateral surface having a second diameter greater than the first diameter, and an upward-facing facing surface between the top surface and the lateral surface configured to engage the receiver cavity ceiling surface to inhibit upward movement of the bone anchor upper portion within the receiver bore, wherein sliding engagement between the receiver cavity curvate seating surface and the bone anchor at least partially spherical lateral surface provides for pivotal motion of the bone anchor relative to the receiver, and wherein the at least partial spherical top surface of the bone anchor extends above the receiver inwardly sloping and protruding rigid structure to engage the elongate rod when the elongate rod is secured within the receiver open channel.
