Abstract:
1. A reamer head assembly, comprising: a) a body comprising an annular outer surface, a proximal body end extending to a distal body end along a longitudinal axis, at least two body slots, each body slot having a slot length and a slot depth, the slots positioned within the annular outer surface of the body such that the slot length is not parallel with the longitudinal axis as it extends from the proximal body end to the distal body end, each body slot having a first slot angle measured between the slot length and the longitudinal axis of the body; b) at least two continuous reamer blades, each reamer blade comprising a blade length extending from a proximal blade end adjacent to the proximal body end to a distal blade end adjacent to the distal body end, wherein each reamer blade comprises a reamer blade attachment portion and a reamer blade cutting portion partitioned between the proximal and distal blade ends by a reamer blade transition line that extends along the reamer blade length; and c) wherein the reamer blades are positioned about the body, spaced apart from each other by a blade separation distance with a blade separation area therebetween, such that each reamer blade attachment portion is positioned within its respective body slot, the reamer blade cutting portion extending outwardly from the outer surface of the body and wherein each reamer blade is bent at an angle along the transition line such that the blade cutting portion and the blade attachment portion are not coplanar.
