Abstract
A retractor system includes a frame and first and second retractor blades. The frame includes first and second securement features. At least one of the first and second securement features is movable with respect to the frame when the first and second securement features is mounted to the frame. Proximal portions of the first and second refractor blades are secured proximate the first and second securement features respectively. In a first position the first and second refractor blades are laterally opposed. Movement of the securement feature adjusts the angle of at least one of the retractor blades so that at least one of the retractor blades may be adjusted between an acute angle and an obtuse angle to horizontal.
