1. A surgical retractor comprising: a laterally extending rack having a proximal and distal portion; a first arm connected to the rack at a first location and extending longitudinally from the first location, said first arm having a first segment, a middle hinged segment, and a third segment, said middle hinged segment connected intermediate to the first segment at a first pivot extending along a first axis and third segment at a second pivot extending along a second axis, said first and second axes extending parallel to the rack; a moveable second arm having a housing for slidably engaging a portion of the rack, said second arm extending longitudinally from the housing; said housing having an adjustment mechanism for allowing the positioning of the housing relative to the rack at a desired location and the at least temporary fixation of the housing at the desired location; and wherein said middle segment of said first arm extends both longitudinally and laterally toward the second arm thereby laterally displacing the third segment relative to the first segment toward the second arm, wherein the middle hinged segment and the third segment are capable of rotating about their respective axes while the third segment remains laterally offset from the middle hinged segment, and wherein the second pivot is laterally displaced relative to the first pivot closer to the second arm.
