Method and apparatus for performing spinal surgery

摘要

Implants, instruments, and methods for performing surgical procedures on the spine, including one or more of creating an operative corridor to the spine, delivering implants to the spine, fusing one or more segments of the spine, and fixing one or more segments of the spine. A method for attaching a fixation system to the spine of a patient, the fixation system including at least two bone anchors and a spinal rod linking the at least two bone anchors.

主权项

1. A posterior spinal retractor for a maintaining an access corridor to a site along the posterior spinal column on which a surgical procedure is performed, the surgical procedure including the use of first and second bone anchors anchorable into first pedicle of a first vertebra and a second pedicle of a second vertebra, respectively, comprising:
a retractor having a first arm, a first retractor blade attachable to the first arm and having a distal end and a proximal end, a second arm, and a second retractor blade attachable to the second arm and having a distal end and a proximal end, the first arm and the second arm being movable relative to each other in a first direction, wherein the distal end of the first retractor blade is temporarily anchorable in position relative to the first pedicle via coupled engagement with the first bone anchor, the coupled engagement permitting angular adjustability of the distal end relative to the first bone anchor and the proximal end of the first retractor blade is pivotable relative to the first arm, and wherein the distal end of the second retractor blade is temporarily anchorable in position relative to the second pedicle via coupled engagement with the second bone anchor, the coupled engagement permitting angular adjustability of the distal end relative to the second bone anchor and the proximal end of the second retractor blade is pivotable relative to the second arm; and a third retractor blade moveable relative to the first and second retractor blades in a second direction orthogonal to the first direction.
