Abstract: A forceps for clamping, grasping, manipulating, coagulating/desiccating and cutting tissue includes a shaft portion having a proximal end, a distal end and first and second jaw members pivotally attached to the distal end of the shaft by a pivot assembly. Each of the jaw members including an opposing inner facing surface having a plurality of wave forms disposed thereon for engaging tissue therebetween. The wave forms disposed on the inner facing surface of the second jaw member being complimentary to the wave forms on the inner facing surface of first jaw member. A handle portion having an actuating assembly is attached to the proximal end of the shaft for imparting movement of the first and second jaw members from a first open position wherein the jaw members are disposed in spaced relation relative to one another to a second clamping position wherein the jaw members cooperate to grasp tissue therebetween.

Abstract: A bipolar electrosurgical instrument for clamping, grasping, manipulating, and sealing tissue includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof. The handle being operable to effect movement of the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The bipolar instrument is connectable to a source of electrical energy having a first electrical potential connected to one of the jaw members and a second electrical potential connected to the other of the jaw members such that the jaw members are capable of selectively conducting energy through tissue held therebetween to effect a seal. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.

Abstract: A laparoscopic bipolar electrosurgical instrument can apply a large closure force between its jaws without damaging the small yoke assembly.
