摘要： An embodiment of a method includes selecting a countersink depth setting with a linear countersink adjustment mechanism of a distractor-inserter, positioning distal ends of blades of the distractor-inserter between the two vertebral bodies to be separated, driving a head block assembly of the distractor-inserter forward until the retraction members of the distractor-inserter engages respective outer faces of the vertebral bodies, and retracting the distal ends of the blades and the tip from between the vertebral bodies, wherein the vertebral bodies compress the disc implant and hold the disc implant between the vertebral bodies at the countersink depth. A distractor-inserter includes first and second retraction members disposed within channels of the blades, and a countersink adjustment mechanism configured to linearly adjust a distance between a tip and the retraction members to thereby linearly adjust a countersink depth of an implantable element inserted between two distracted elements.
