Abstract
A minimally invasive surgical access device that allows access to a pathology being treated while significantly reducing the risk of damaging anatomical structures proximate the pathology. The access device includes a base portion having a central bore extending therethrough, and retractor blades pivotably mounted to the base portion. An insertion handle is coupled to the base portion to thread the retractor blades into the patient. The insertion handle is removed from the base portion, and a core hollow screw is threaded into the base portion to separate the retractor blades to gain access to the pathology through the hollow screw.
