    摘要: Disclosed are devices, methods and systems for manipulating a pedicle screw assembly and for inserting and reducing a rod relative to the pedicle screw assembly. The system can include a cannula assembly having a reduction cannula with an internal bore extending between a proximal region and a distal region and an insertion cannula co-axially positioned within the internal bore of the reduction cannula. The insertion cannula includes a pair of opposed prongs extending distally from a distal region of the insertion cannula, wherein each prong is interposed between a pair of flexible projecting elements. The pair of opposed prongs of the insertion cannula and the distal region of the reduction cannula are aligned to collectively define an opening that is sized and shaped for receiving a spinal rod. The device also can include an annular collar mounted on the proximal region of the reduction cannula and rotatably coupled to a proximal region of the insertion cannula. The cannula assembly can also be a pivoting cannula assembly.

    摘要: Disclosed are embodiments of a removable tip device, which include a bone penetration feature at a distal end and a securing feature that allows the removable tip device to be removably secured to a distal end of various embodiments of a bone coring device. Some embodiments of the removable tip device include features that assist in transmitting torsional loads from the bone coring device to the bone removal feature. In addition, some embodiments of the removable tip device include a protective element that is configured to provide a protective surface for a distal feature of the bone coring device.

    摘要: Disclosed is a spinal stabilization device having a plurality of elongate arms having a distal end portion and a proximal end portion, wherein the elongate arms define an interior volume between the distal end portion and the proximal end portion; at least one limit band coupled circumferentially to one or more of the plurality of elongate arms; and a tensioning element positioned within the interior volume. The plurality of elongate arms can transition from a constrained, delivery configuration that is radially contracted and axially elongated to a relaxed, deployment configuration that is radially expanded and axially shortened.
