Abstract: An orthopaedic reamer includes a shell and a cutting tooth arrangement formed in the shell. The cutting tooth arrangement includes a cutting tooth having a predefined profile with a cutting edge having a cutting depth, and a depth-of-cut feature positioned forward of the cutting tooth, relative to a direction of movement of the shell at the location of the cutting tooth. The depth-of-cut feature has a control depth which controls a cutting depth of the cutting tooth during surgery.

Abstract: A driver for an orthopaedic reamer includes a drive shaft defining an axis of rotation; a reamer connector connected to the drive shaft and having at least one first annular portion about the axis of rotation and at least one second annular portion about the axis of rotation radially spaced from the at least first annular portion to define at least one holding recess therebetween; and a collar associated with the reamer connector and slidable in a direction of the axis of rotation between a first position and a second position, the collar being unaligned with the at least one holding recess circumferentially about the axis of rotation in the first position and, in the second position, being rotatably locked to the reamer connector and having a portion aligned with the at least one holding recess circumferentially about the axis of rotation.

Abstract: An angular surgical driver including a first rotatable member, a second rotatable member, an angled housing and a plurality of pins. The first rotatable member and second rotatable member are angularly associated with each other. The angled housing is rotatably connected to the first rotatable member and the second rotatable member. A plurality of pins drivingly connecting the first rotatable member to the second rotatable member.

Abstract: An orthopaedic reamer, including a generally hemispherical shell rotatable about an axis having a plurality of tongues. Each tongue partially defines a corresponding C-shaped opening with a substantially constant width. Each tongue includes a cutting segment. The cutting segment includes at least one notch and a plurality of cutting teeth. Adjacent cutting teeth are separated by a corresponding notch. Each notch of each tongue has a corresponding cutting tooth of another tongue overlapping a cutting position of the notch during rotation of the orthopaedic reamer about the axis.

Abstract: An orthopaedic reamer assembly includes a reamer with a generally hemispherical shell having a concave side and at least one attachment feature associated with the concave side. A driver is attachable to the reamer. The driver includes a shaft with a reamer end. The reamer end removably attaches to at least one attachment feature.

Abstract: An orthopedic reamer assembly for minimally invasive surgery including a reamer and a driver.

Abstract: A method of manufacturing an orthopaedic reamer includes the steps of: forming a shell having a cutting face; cutting a plurality of openings in the shell, each opening defining a cutting edge of a tooth and a pair of relief cuts extending transverse from opposite ends of the cutting edge, each relief cut terminating at a base end; and bending each cutting tooth in a single bending operation about an axis extending between the base ends, with each cutting edge having a shape after the bending step which is predefined by the cutting step.
