Claim Text:
1. A tissue retractor comprising: a pair of arms pivotally coupled to each other and each having a finger grip portion on a first end and a working portion arranged on an opposite second end, wherein each of the second ends comprises an elongated shaft having a longitudinal axis extending axially therethrough; and a pair of paddles each having a planar engagement body and a mounting portion pivotally coupled to a corresponding elongated shaft, the paddles being selectively rotatable about the respective longitudinal axes, wherein the paddles are coupled to the corresponding elongated shafts such that the paddles are rotationally unbiased relative to the elongated shafts, wherein an angle between the respective longitudinal axes changes as the arms pivot relative to each other, wherein rotation of the paddles around the respective longitudinal axes is limited to a predetermined range that is less than 360 degrees, and wherein each of the paddles includes a mounting hub, each mounting hub includes one of a slot or a pin and each of the elongated shafts includes the other of the slot or the pin, each slot includes terminal ends, and the pins are configured to ride along the corresponding slots and engage the terminal ends, thereby limiting pivoting motion of the paddles relative to the elongated shafts.
