Claim 1
Independent Claim
178 words
Surgical forceps comprising a pair of cross members having securing means for pivotally securing the cross members to one another, said cross members having a first set of arms extending in a first direction from the securing means and a second set of arms secured to said first set of arms and extending in an opposite direction from said securing means, said first set of arms adapted with gripping means for pivoting said arms about the securing means, the second set of arms terminating with a set of equal length mating jaws extending in a plane substantially perpendicular to the plane containing the first set of arms and curved to the anatomical curve of the cervix and wherein the outer edge of each of the extending jaws has three spaced apart notches oriented such that when the jaws are in a closed mated position the jaws are disposed in parallel planes with the notches in abutting alignment, and said notches in each jaw being spaced apart from an adjacent notch by between about 3/8 and about 3/4 inch.
