Abstract
A midline retractor provides access for the placement of PARS screws and other surgical sites. A lower profile allows for better visualization of the patients anatomy and provides better access for surgical instruments. The retractor may include integrated lighting, such as fiber optic lighting or other suitable lighting. The blades of the retractor may include a textured profile, such as diamond plating, grooves, etching or any other desired textured treatment on the blades. The texture on the blades may keep tissue from migrating down the blades and may prevent the blades from slipping up and out of the patient. The PARS retractor may include a blade rotation locking mechanism and/or a blade toe feature that allows for ease of use and an adjustable blade toe. The retractor may also include a rack release that provides for free movement of the rack.
