1. An adjustable surgical retractor frame comprising:
a first frame segment including a middle section disposed between a first end and a second end;
a second frame segment including an intermediate section and a pair of end sections projecting from the same side of the intermediate section, said pair of end sections maintaining a substantially parallel orientation with respect to each other, each of said pair of end sections including a top surface and a bottom surface;
a pair of connectors, the pair of connectors being configured for coupling the first frame segment to the second frame segment so as to form said adjustable surgical retractor frame, each of the pair of connectors comprising:
a ratchet housing configured for connecting to said first frame segment;
a channel formed within the ratchet housing, the channel being configured to receive one of the pair of end sections of said second frame segment when the channel is aligned about parallel with said one of the pair of end sections but vertically offset therefrom and then the relative vertical position between the channel and said one of the pair of end sections is changed so that said one of the pair of end sections is received within the channel; and
a ratchet fastener configured for releasably holding the one of the pair of end sections of said second frame segment within said channel.
