Total Claims: 18
Claim 1
Independent Claim
199 words
A surgical forceps comprising a pair of cross members having securing means for pivotally securing the 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 first set of arms and said second set of arms about the securing means; the second set of arms comprising a pair of end members substantially disposed in a plane containing the first set of arms and directed away from the longitudinal axis of the first set of arms, and the extremity of the end members terminating with a set of mating jaws disposed in a plane substantially perpendicular to the plane containing the securing means, said set of jaws comprising a first jaw having spaced-apart notches disposed in its outer lengthwise edge and a second jaw having a like number of notches disposed in its outer lengthwise edge such that when the jaws are in a closed mated position, the notches are in abutting alignment.
Claim 2
Dependent Claim
199 words
A surgical forceps comprising a pair of cross members having securing means for pivotally securing the 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 first set of arms and said second set of arms about the securing means; the second set of arms comprising a pair of end members substantially disposed in a plane containing the first set of arms and directed away from the longitudinal axis of the first set of arms, and the extremity of the end members terminating with a set of mating jaws disposed in a plane substantially perpendicular to the plane containing the securing means, said set of jaws comprising a first jaw having spaced-apart notches disposed in its outer lengthwise edge and a second jaw having a like number of notches disposed in its outer lengthwise edge such that when the jaws are in a closed mated position, the notches are in abutting alignment.
