Abstract:
1. A surgical retractor system, comprising: a substantially rigid frame having an upper surface and a lower surface, the substantially rigid frame defining a horizontal plane, a plurality of arms connected to the frame, each arm having a longitudinal axis extending from a proximal end to a distal end, wherein at least one arm is moveable relative to the frame, and wherein the relative movement is constrained to a direction along the longitudinal axis of the arm, at least one retractor blade removably connected to each of the plurality of arms adjacent the distal end, the blade extending generally perpendicular to the longitudinal axis and being fixably rotatable about the longitudinal axis of the arm to which it is connected and a bar clamp mechanism received within the frame and associated with at least one arm to releasably clamp the arm in a fixed position relative to the frame, wherein the bar clamp mechanism includes a latch member and a biasing member, the latch member is biased in a first position to clamp the arm in a fixed position relative to the frame and is not biased in a second position to allow the arm to move relative to the frame, wherein at least a portion of the latch member extends beyond the frame allowing direct actuation of the latch member from the first position to the second position, and wherein the frame includes an opening extending from the upper surface to the lower surface providing access to the latch member allowing actuation of the latch member from the first position to the second position through the use of a manual retraction tool.
