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. |

1. An angled surgical tool for removing tissue from within an intervertebral space, comprising an elongated handle that is substantially cylindrical in shape, a proximal end of said handle is configured to connect to a tubing for transmitting a gas or fluid from a gas or fluid source, a distal end of said handle is connected to a shaft, and said shaft having a head portion integral with a shaft distal end, the head portion including a distal tip located at a distal terminus of the head portion, said head portion being offset from the handle portion by an angle such that the head portion is angled towards the handle, said angle being tilted toward said shaft at an angle ranging from 5 to 45 degrees, so that the head portion may enter a disk space when an operating cannula is not at a right angle to the disk space, the head portion having a top surface consisting of two separate rows of rasp features comprising protrusions adapted to displace material, said two separate rows of rasp features having a flat portion between the rows for trapping of material distracted from the intervertebral space, said rasp features adapted to remove tissue and debris disposed within a vertebral endplate in an intervertebral space, said top surface being devoid of apertures. |
