摘要： 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.

摘要： A laparoscopic bipolar electrosurgical instrument can apply a large closure force between its jaws without damaging the small yoke assembly. The instrument comprises: a first jaw having a first flange with a first slot, and a second jaw having a second flange with a second slot, wherein the first and second jaws are located at a distal end of the instrument and comprise an electrically conductive material for conducting bipolar electrosurgical current therebetween; a yoke attached to a pushrod and positioned to electrically insulate the first flange from the second flange, the yoke having a first side facing the first flange and a second side facing the second flange, the yoke further comprising a first shoulder and a second shoulder, a first pin located on the first side and movably engaged with the first slot; a second pin located on the second side and movably engaged with the second slot; the first slot and the second slot shaped such that an angle, subtended by the first and second jaws, decreases with distal motion of the pushrod, and first and second cul-de-sacs positioned respectively in the first and second slots to relieve shear stresses on the first and second pins approximately when the first and second shoulders respectively engage the first and second flanges to provide a closure force between the first and second jaws.

摘要： 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. One embodiment of the forceps includes a pair of electrodes clamped on the inner facing surface of each jaw member for imparting electrosurgical energy to the tissue grasped therebetween.
