Abstract
A surgical dissector has two sets of dissecting jaws with serrated inner surfaces to firmly grasp and dissect tissue. The second set of jaws projects transversely from the first set of jaws. Both sets of jaws are curved, and in one alternative, curvature of the second set of jaws is in a direction opposite to the curvature of the first set of jaws, while in the second alternative, the curvature of the second set of jaws is in the same direction as the curvature of the first set of jaws. In a first embodiment, for use during laparoscopic surgery, the dissector is positioned within a trocar for insertion into the body. In a second embodiment, for use during open surgery, a forceps type of dissector is disclosed.
