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.

摘要： A method is disclosed. The method includes providing a plurality of blades, movably connecting the plurality of blades to an outer member via a plurality of arm members, disposing the plurality of blades in a human or animal body, and moving the plurality of blades from a first position outward to a second position when the plurality of blades are disposed in the human or animal body. The plurality of blades are disposed further from each other in the second position than the first position. Moving the plurality of blades outward from the first position to the second position includes moving the plurality of arm members. Moving the plurality of blades includes maintaining equidistance between the plurality of blades as the plurality of blades move from the first position to the second position.

摘要： An implant is disclosed. The implant has a base including an extension arm cavity and a ratchet block cavity that intersects the extension arm cavity, an extension arm that is movably disposed in the extension arm cavity, and a ratchet block that is movably disposed between a first position and a second position in the ratchet block cavity. The ratchet block when disposed in the first position allows movement of the extension arm in an upward direction out of the extension arm cavity and blocks movement of the extension arm in a downward direction into the extension arm cavity. The ratchet block when disposed in the second position allows movement of the extension arm both in the upward direction out of the extension arm cavity and the downward direction into the extension arm cavity.

摘要： A pedicle screw device for fixating at least two adjacent vertebral bodies is presented. The device consists of a bone screw which is implanted into the pedicle of a vertebral body. A second bone screw is implanted into the pedicle of a second vertebral body. A polyaxial head is then inserted over each bone screw. The polyaxial heads can then be slid into a retaining position on the bone screw, allowing them to rotate about the spherical portion of the bone screw. The polyaxial heads are then attached to one another with a rod. Finally, a locking screw is inserted into the polyaxial heads to force the rod against the bone screw as well as the polyaxial head, locking them in place. The rod also serves to prevent the polyaxial head from disconnecting from the bone screw.

摘要： An adjustable spinous process implant configured with one or more flexible members that extend from the implant and are further attachable to anchors implanted in adjacent vertebrae. The adjustable spinous process implant comprises a spacer that is shaped to fit between two adjacent spinal processes. The flexible members extend from one or more points on the adjustable spinous process implant and attach the anchors to provide tension and stability to the overall implant construct. The anchors are configured with a tensioning mechanism that enables the flexible members to be tensioned within the anchor.

摘要： The present invention generally relates to an expandable interbody implant. Specifically, the present invention is an expandable interbody implant having an anterior and posterior wedge and opposing endplates. In some embodiments, a slot parallel to the wedge face may be located on each endplate, with a pin holding the endplates to the respective wedges. Additionally, in some implementations, lateral rails may extend from the anterior wedge to the posterior wedge. Furthermore, the expandable implant may include a locking mechanism configured to prevent unwanted collapse.
