Interbody fusion device and method of operation

摘要

An interbody fusion device is provided that includes an interbody cage, a fixation system and an actuation mechanism to deploy one or more blades. The cage acts as an intervertebral spacer and provides resistance to the compressive loads in the spinal column. The fixation system includes an anchor and a ramp. These components could be manufactured from various medical grade materials.

1. An interbody fusion device comprising:
a cage having a first contact surface and a second contact surface opposite said first contact surface; a ramp fixedly coupled to said cage, said ramp having a curved surface thereon; and an anchor having a body movably coupled within said cage, said body being linearly movable between a first position and a second position, wherein said first position and said second position are positioned within said cage, said anchor having at least one blade extending from said body and having an end adjacent said ramp, wherein said at least one blade cooperates with said curved surface to direct said at least one blade from said first contact surface when said body moves from said first position to said second position, wherein a curvature of said at least one blade is curved in a direction toward said first position when said body is in said second position; wherein said at least one blade includes at least one slot; wherein said at least one blade includes a pair of opposing semi-circular surfaces and a pair of opposing sides between said end and said body and transverse to said pair of opposing surfaces, wherein at least one of said opposing sides includes an edge, said at least one slot being positioned on said edge.
