Abstract

A surgical instrument suitable for preparing an intervertebral disc space includes an outer sleeve, an instrument head, an inner shaft, a handle, a universal joint, a coupling member, and a drive mechanism. The outer sleeve includes a proximal end, a distal end and a longitudinal axis. The instrument head defines a longitudinal axis and is disposed at the distal end of the outer shaft. The inner shaft is slidably disposed within the outer sleeve and includes a proximal end, a distal end and a longitudinal axis coaxially aligned with the longitudinal axis of the outer sleeve. The drive mechanism is coupled between the outer sleeve and the inner shaft and actuates the outer sleeve axially relative to the inner shaft, thereby setting an angle of the longitudinal axis of the instrument head in relation to the longitudinal axis of the inner shaft.
