A flexible shaft includes a tubular body extending along a central longitudinal axis and having proximal and distal ends opposite one another. The flexible shaft also includes a slot defined by the tubular body and extending along a helical path around and along at least a portion of the body between the proximal and distal ends. The helical path extends around the portion of the body for a plurality of rotations. The slot defines at least two teeth adjacent one another along a direction parallel to the central axis. Each tooth of the two teeth has a feature. In some implementations, a line extending through center points of the features on the two teeth is angularly offset from the central longitudinal axis. In some implementations, a line parallel to the central longitudinal axis intersects a different point on each feature of the two teeth.

Rotationally balanced slot pattern for flexible shafts

A reamer shaft extension includes a shaft positioned between a first end having a first coupling and a second end having a second coupling. The first coupling of each reamer shaft extension is selectively couplable with the second coupling of another reamer shaft extension such that a select amount of reamer shaft extensions are assembled together to form a reamer shaft extension assembly for use in a reaming procedure. Each reamer shaft extension further has a sufficiently short enough length such that each reamer shaft extension is insertable within a sterilization tray for use in a sterilization procedure.
