Devices and Methods for Preparing an Intervertebral Workspace

摘要

Tools adapted for spinal distraction are provided. More specifically, tools having an elongate shaft connected to a head portion are provided for imparting a force for displacing vertebral bodies. The tools may comprise features, such as textured surfaces or the ability to transmit pressure, for cleaning and preparing a spinal disc space for subsequent tools and procedures. A plurality or set of distraction tools is contemplated where the plurality of tools is made up of tools having various distinctions from one another. Such distinctions may be in the way of length, width, angle, and other geometric features or may comprise differences in materials or additional features.
