ANGLING INSERTER TOOL FOR EXPANDABLE VERTEBRAL IMPLANT

摘要

The present invention relates to a method of inserting an implant comprising providing an expandable vertebral implant. The method further may comprise providing an angling inserter tool. The angling inserter tool comprises a handle portion, a base portion, and a tip assembly, the base portion being disposed between the handle portion and the tip assembly. The method further may comprise distally advancing a central shaft of the tip assembly with rotation into an opening in the expandable vertebral implant to secure the angling inserter tool to the expandable vertebral implant. The method further may comprise positioning the expandable vertebral implant in a patient's spine. The method further may comprise for causing the tip assembly to angulate with respect to a longitudinal axis of the angling inserter tool, wherein the internal shaft is coaxial with an outer cylinder of the base portion.
