Patent ID: 7799029

Claim:
An instrument for compacting bone material in preparation for inserting an implant, the implant having an outer periphery, said instrument comprising: a first component defining a longitudinal axis thereof, the first component including angled walls; and a second component and a third component, each of said second and third components moveably associated with said first component, said second component and said third component moveable at least partially in a radial direction outwardly from the longitudinal axis of said first component, wherein either said conical portion of said first component or both said second and third components define a groove and wherein the other of said conical portion of said first component said second and third components comprises a protrusion for cooperation with said groove, such that the protrusion extends into said groove, thereby coupling said first component to said second component and said third component, said second and third components slidingly engaged to said first component along said angled wall, such that as said angled wall is moved downwardly, said second and third components are pushed outwardly by said angled wall, said second component and said third component are completely separated from one another, such that said second component and said third component can move independently of one another; wherein said second and third components define an outer periphery, said outer periphery having a shape that generally replicates the outer periphery of the implant.
