Abstract:
1. An implant inserter device, comprising an outer collar having a proximal end, a distal end, an aperture extending from said proximal end to said distal end, an interior surface, and a plurality of cammed surfaces formed on said interior surface extending proximate from said distal end; an inner sleeve having a proximal end, a distal end, an aperture extending from said proximal end of said inner sleeve to said distal end of said inner sleeve, an exterior surface, and a plurality of ribs projecting outwardly from said exterior surface proximate to said distal end of said inner sleeve, said inner sleeve being slidably and rotatably received within said aperture of said outer collar such that said inner sleeve and said outer collar are arranged substantially coaxially relative to each other, each of said plurality of ribs being releasably engageable with a corresponding one of said plurality of cammed surfaces when said inner sleeve is rotated relative to said outer collar, whereby when said plurality of ribs releasably engages said plurality of cammed surfaces, said distal end of said inner sleeve collapses from an undeformed position, in which said distal end of said inner sleeve does not grip an implant housed within said inner sleeve proximate to said distal end of said inner sleeve, and a deformed position, in which said distal end of said inner sleeve grips the implant; and a push rod slidably received within said aperture of said inner sleeve, said push rod being movable between an extended position and a retracted position.
