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 having a proximal end configured to be connected to a tubing for transmitting a gas or fluid from a gas or fluid source and a distal end connected to a shaft, said shaft having a head portion including a distal tip located at a distal terminus of the head portion, said head portion being offset by an angle such that the head portion is angled towards the shaft at an angle ranging from 5 to 45degrees, the head portion having a top surface consisting of rasp features adapted to remove tissue and debris disposed within a vertebral endplate in an intervertebral space, said top surface being devoid of apertures. 2. The surgical tool of claim 1, wherein said shaft further comprises an internal conduit for conveying a pneumatic pressure through said shaft. 3. The angled surgical tool of claim 1, wherein vacuum pressure is supplied to the shaft, thereby drawing debris toward said shaft distal end. 4. The angled surgical tool of claim 1, wherein a quantity of said fluid or gas is directed through a portion of said tool. 5. The angled surgical tool of claim 1, wherein a positive or negative pressure is transmitted through said shaft. 6. The angled surgical tool of claim 1, wherein said shaft is disposable. 7. The angled surgical tool of claim 1, wherein said shaft is detachably anchored to said head portion. 8. The angled surgical tool of claim 1, wherein said head is detachably anchored to said shaft and wherein the head is disposable. 9. The angled surgical tool of claim 1, wherein said tool facilitates the removal of at least an outer most cell layer of bone to gain access to vascular bone tissues within the intervertebral space. 10. The angled surgical tool of claim 1, wherein said head portion comprises peripheral outer surfaces capable of dislodging, scraping or cutting materials in the intervertebral space. 11. The angled surgical tool of claim 1, wherein said head portion includes flutes for guiding materials that have been dislodged from portions of the intervertebral space. 12. The angled surgical tool of claim 1, wherein said fluid or gas blasts or clears the intervertebral space of debris. 13. The angled surgical tool of claim 1, wherein said fluid comprises one of ambient air, inert gasses, oxygen, water, or saline. 14. The angled surgical tool of claim 1, wherein said head portion is selectively rotatable. 15. The angled surgical tool of claim 1, wherein a quantity of said fluid or gas is directed through a portion of said tool. 16. An angled surgical tool for removing tissue from within an intervertebral space, comprising an elongated handle having a proximal end configured to be connected to a tubing for transmitting a gas or fluid from a gas or fluid source and a distal end connected to a shaft, and said shaft having a head portion including a distal tip located at a distal terminus of the head portion, said head portion being offset by an angle such that the head portion is angled towards the shaft at an angle ranging from 15 to 25 degrees, the head portion having a top surface consisting of rasp features adapted to remove tissue and debris disposed within a vertebral endplate in an intervertebral space, said top surface being devoid of apertures. 17. An angled surgical tool for removing tissue from within an intervertebral space, comprising an elongated handle having a proximal end and a distal end connected to a shaft, said proximal end configured to be connected to a tubing to convey vacuum pressure to the shaft, thereby drawing debris through said shaft, said shaft having a head portion including a distal tip located at a distal terminus of the head portion, said head portion being offset by an angle such that the head portion is angled towards the shaft at an angle ranging from 5 to 45 degrees, the head portion having a top surface consisting of rasp features adapted to remove tissue and debris disposed within a vertebral endplate in an intervertebral space, said top surface being devoid of apertures. 18. The angled surgical tool of claim 17, wherein said head portion is selectively rotatable. 19. The angled surgical tool of claim 17, wherein said head is detachably anchored to said shaft. 20. The angled surgical tool of claim 17, wherein said head is disposable.
