Surgical positioning assembly and related systems and methods

摘要

Systems and methods for placing spinal implants within an intervertebral region. In some embodiments, a surgical positioning tool may be provided that allows for access to an implantation site to be gained along a first axis, and then allows a spinal implant to be repositioned from the first axis to a second axis at an angle with respect to the first axis. The spinal implant may, in some embodiments, comprise a recess comprising two adjacent bars configured to engage elements of the surgical positioning tool to allow for the aforementioned repositioning.

主权项

1. A spinal implant system, comprising:
a spinal implant, comprising:
a pivot bar; anda draw bar; and a surgical positioning tool, comprising:
a handle configured for holding the surgical positioning assembly along a first axis;a retention mechanism coupled with the handle and configured to selectively couple the spinal implant to the surgical positioning assembly, wherein the retention mechanism is further configured to position the spinal implant at least substantially along the first axis, and wherein the retention mechanism is configured to engage with the pivot bar on the spinal implant;a draw rod configured to selectively reposition the spinal implant relative to the surgical positioning assembly from at least substantially along the first axis to at least substantially along a second axis that is distinct from the first axis, wherein the draw rod comprises a hook structure configured to engage with the draw bar on the surgical positioning assembly;a draw knob coupled with the draw rod; anda rod received in a threaded channel, wherein the draw rod is configured to be actuated to reposition the spinal implant relative to the surgical positioning assembly from at least substantially along the first axis to at least substantially along a second axis by rotating the knob to cause the hook structure to move with respect to the retention mechanism.
