Abstract
A tissue retractor with an adjustable center claw. The retractor includes two pivoted retractor arms. An axially and angularly displaceable, spring biased clamping mechanism is positioned on the pivot axis. In a mounting position, a elongated clamping element aligns with a slot in the center claw. When the center claw is positioned and the clamp moves to its clamping position, the elongated clamping member clamps the center claw in position. The counterfacing surfaces of the center claw and the clamping member are toothed to provide a positive one-way ratchet clamp.
