Patent ID: 7670343

Claim:
A tool for reaming a cavity in bone comprising: a longitudinal shaft having a distal end and a proximal end, said longitudinal shaft extending along a first axis; a cutting tool selectively attachable to said distal end opposite said proximal end; a guide having a body that defines a second axis through an elongated opening, the guide including a unitarily formed locator member extending therefrom, wherein said locator member includes a spherical outer engaging surface and defines a concave recess on an inner surface that accommodates said cutting tool, said locator member being engageable to a first portion of the bone providing a reference point relative to said cutting tool while said cutting tool engages a second portion of the bone during cutting; an arm operably connected between said body and said locator member, said arm having a first section that extends along a third axis that is parallel to and offset from said first axis; and wherein said body is slidably advanced onto said longitudinal shaft through said opening from said proximal end to an operating location intermediate said distal end and said proximal end in an assembled position, said first and second axes being collinear.
