SPINAL STABILIZATION CAM-LOCKING CROSS-CONNECTOR

摘要

An adjustable spinal implant device including a first member and a second member, the first member adapted to receive the second member and to lock the second member in position relative to the first member. The first and second members may each comprise coupling portions adapted to couple to a spinal stabilization rod with a snap-fit. Cam locks may be adapted to be rotatably positioned in each member, wherein each member comprises a cam bore configured to receive a cam lock. The first cam lock and second cam lock may be each rotatable between a locked position and an open position.

1. An adjustable spinal implant device, comprising:
a first member and a second member, the first member adapted to receive the second member and to lock the second member in position relative to the first member; wherein the first member comprises a first coupling portion adapted to couple to a first spinal stabilization rod with a snap-fit; wherein the second member comprises a second coupling portion adapted to couple to a second spinal stabilization rod with a snap-fit; wherein the first coupling portion comprises a first rod recess adapted to receive the first spinal stabilization rod; wherein the second coupling portion comprises a second rod recess adapted to receive the second spinal stabilization rod; a first cam lock adapted to be rotatably positioned in the first member, a second cam lock, adapted to be rotatably positioned in the second member; wherein the first member comprises a first cam bore configured to receive a first cam lock; wherein the second member comprises a second cam bore configured to receive a second cam lock; wherein the first cam lock and second cam lock are each rotatable between a locked position and an open position; wherein the first rod recess of the first coupling portion is adapted to receive the first spinal stabilization rod when the first cam lock is in an open position; wherein the first member is adapted to block the first spinal stabilization rod from exiting the rod recess of the first coupling portion when the first cam lock is in a locked position; wherein the second rod recess of the second coupling portion is adapted to receive the second spinal stabilization rod when the second cam lock is in an open position; and wherein the second member is adapted to block the second spinal stabilization rod from exiting the rod recess of the second coupling portion when the second cam lock is in a locked position.
