<P>PROBLEM TO BE SOLVED: To provide a tool set for implanting bone screws in a human spine, followed by the implantation of a longitudinal connecting member into the bone screws. <P>SOLUTION: A tool set includes a pair of independently mountable and manipulatable elongate guide tools 1 that form a unitary tool guide when desired. Each guide tool includes attachment structure for independent operable connection of the guide tool to an arm of the bone screw 4. The bone screw/guide tool attachment structure includes an undercut and/or recess so as to resist separation of the guide tool member from an attached bone screw. A removable stabilizer cooperating with the pair of guide tools places such tools in a set spaced relation to one another when desired. <P>COPYRIGHT: (C)2012,JPO&INPIT |
