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 at least one of the first and second securement features is mounted to the frame. The first and second retractor blades each have a distal portion and a proximal portion. The proximal portions of the first and second retractor blades are configured to be secured proximate to the first and second securement features respectively, such that the first and second retractor blades may be positioned in a first position wherein the first and second retractor blades are laterally opposed. A movement of the at least one securement feature that is movable with respect to the frame adjusts the angle of at least one of the retractor blades, wherein the at least one of the retractor blades may be adjusted between a first angle less than 90 degrees to horizontal and second angle greater than 90 degrees to horizontal.
