Abstract:
1. A corpectomy device, comprising: an outer tubular member having a longitudinal axis and a passage; an inner tubular member that is axially moveable with respect to said longitudinal axis and non-rotatable in said passage of said outer member, said inner member defining a chamber with said outer member; and a locking clip engagable with said outer member and said inner member and moveable between an unlocked position and a locked position for locking said outer member and said inner member in a relative axial position with respect to one another, said locking clip having an inner surface including a first longitudinally extending surface portion and a second longitudinally extending surface portion, at least said second surface portion being curvilinear, and said first surface portion being spaced further from said longitudinal axis than said second surface portions wherein an outer surface of said inner member defines a polygonal cross-sectional shape, including sides and corners and wherein said unlocked position is defined by said corners of said inner member being aligned with said first surface portions of said locking clip, thus facilitating axial movement of said inner member with respect to said outer member.
