a first arm coupled to a rack;
a second arm coupled to the rack;
a first retractor blade coupled to the first arm;
a second retractor blade coupled to the second arm;
a second retraction assembly, the second retraction assembly including:
a carriage configured to engage a blade post having a blade coupled to a distal end and a handle coupled to a proximal end, the blade post adjustable relative to the carriage;
a third retractor blade coupled to the blade post; and
an adaptor having a first region configured to engage the rack and a second region configured to receive a portion of the carriage, wherein the second region permits the carriage to translate in a longitudinal direction of the rack while the first region remains engaged to the rack;
wherein the carriage includes a projection, and wherein the adaptor includes a groove configured to engage the projection such that the projection is configured to translate within the groove of the adaptor, and wherein translation of the projection within the groove of the adaptor moves the third retractor blade in a cranial-caudal direction relative to a patient.
