Patent ID: 8454623

Claim:
A surgical instrument for inserting a spinal implant comprising: a first shaft having an axial bore and including a distal end configured to engage and actuate a first feature of the spinal implant; and a second shaft extending through the axial bore of the first shaft and including a distal end configured to engage and actuate a second feature of the spinal implant, wherein rotation of the first shaft in a first direction actuates the first feature and causes rotation of the second shaft in a second direction to actuate the second feature, wherein the first direction is opposite from the second direction; a drive gear that rotates with the first shaft and a follower gear that rotates with the second shaft, wherein a transfer gear transfers torque from the drive gear to the follower gear; and the distal end of the first shaft and the distal end of the second shaft each include at least one of a splined projection and a hexagonal projection.
