摘要： The present invention generally relates to connectors that connect bone screws with fusion rods for use in stabilizing surgery such as spinal fusion surgery, and to bone screw systems comprising such connectors. In particular, the present invention relates to poly axial screw systems configured to provide a stable but adjustable angular placement. Furthermore, embodiments of the present invention relate to tulip connectors which have a head and a collet, that are configured to rotatably and pivotably lock onto the ball head of a poly axial screw shaft into a manually adjustable locked position, to methods achieving this locked position with or without using a tulip assembly tool, and to the tulip assembly tool that has outer hooks to grab the tulip head and a center dowel to push the collet down into the locked position.
