摘要:
A retractor device for cervical spinal fusion surgery. The retractor device includes a first post assembly having a first pin for mounting the first post assembly to a first vertebral body and a first rod coupled thereto in a multi-axial manner so that the first rod can be pivoted relative to the first pin. The retractor device also includes a second post assembly having a second pin for mounting the second post assembly to a second vertebral body and a second rod coupled thereto in a multi-axial manner so that the second rod can be pivoted relative to the second pin. The retractor device also includes a first retractor blade having a first retractor blade arm slideably engageable to the first rod, and a second retractor blade having a second retractor blade arm slideably engageable to the second rod. The first retractor blade is slid down the first rod and the second retractor blade is slid down the second rod to be positioned and separate the anatomical structures.
