Inter-cervical facet implant distraction tool
First Claim
1. A distraction tool to distract adjacent facets in a spine for insertion of an implant comprising:
- a. a distraction head having a first head component and a second head component;
b. Two or more fingers extending from the first head component and one or more fingers extending from the second head component;
wherein the two or more fingers of the first head component inter align with the one or more fingers of the second head component allowing the first head component and the second head component to be coplanar in the closed position; and
c. an actuatable handle coupled to the distraction head, wherein the plurality of fingers of the first head component and the plurality of fingers of the second head component are non-coplanar when the handle is operated to actuate the first and second head components to an open position.

Abstract
A distraction tool is disclosed which distracts, and preferably sizes, adjoining facets of a spine for an implant. The tool preferably includes a distraction head that has a first and a second head component. The first head component and the second head component preferably include inter-digitated fingers when the distraction head is in a non-distracted position. The tool includes a handle which is actuatable to move the distraction head to a distracted position, whereby the first set and second set of fingers are separated from one another. The tool can include a distraction gauge as well as a locking mechanism. The tool can also include a movement limitation mechanism to control the amount of distraction which the tool undergoes when actuated. The tool can include an insertion feature to allow the implant to be inserted into the facet joint while the tool is distracting the facets apart.
