ABSTRACT:
A tissue spreading forceps for gripping and spreading tissue include two gripping members which are secured to each other by a spring and are rotatable in relation to each other about a pivot. Initial pressure to the spring causes the gripping members to close and grip tissue at two locations. Additional pressure applied to the spring causes the gripping members to spread apart in relation to each other, thereby spreading the tissue.
