System for implanting a rod implant along a spine of a patient

摘要

A tool set for implanting a rod in a human spine in conjunction with bone screws. The tool set includes a pair of end guide tools that receive opposite ends of the rod in channels and under manipulation by a surgeon facilitate transport of the rod toward the bone screws attached to the guide tools. Intermediate guide tools having guiding pass through slots are utilized to guide intermediate locations along the rod toward associated bone screws. An attachment structure operably connects the guide tools to the bone screws. The guide tools each include a lower guide and advancement structure to allow a closure top with mating structure to be rotated and driven downward against the rod and to cooperate with similar structure in the bone screw to seat and lock the rod therein. A method utilizing the tool set allows a surgeon to percutaneously implant the rod in the patient.

主权项

1. A surgical system for implanting an implantable rod adjacent a bone of a spine of a patient, the surgical system comprising:
a) an implantable anchor comprising:
i) a head comprising a first attachment structure and a rod receiving channel; andii) a distal portion distally extending from the head and configured to be received in an anchoring fashion in the bone; and b) an elongated guide tool comprising:
i) a proximal end comprising a proximal opening extending around a longitudinal axis of the elongated guide tool;ii) a distal end opposite the proximal end, the distal end comprising a distal opening extending around the longitudinal axis of the elongated guide tool, the distal and proximal openings opening in opposite directions from each other;iii) a wall comprising an interior surface;iv) a channel radially inward of the wall, the interior surface of the wall defining the channel;v) a side opening through the wall to the channel, the side opening extending longitudinally along the elongated guide tool from the distal opening toward the proximal opening; andvi) a second attachment structure distal the proximal end and releasably attachable to the first attachment structure so as to releasably attach the head to the elongated guide tool near the distal end.
