Assignee:
Covidien AG - Neuhausen am Rheinfall
International Classification:
A61B 18/14
US Classification:
606 51, 606205, 606 45
Abstract:
An open electrosurgical forceps for sealing tissue includes a pair of first and second shaft members each having a jaw member disposed at a distal end thereof. The jaw members are movable from a first position in spaced relation relative to one another to a subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes an electrically conductive sealing plate for communicating electrosurgical energy through tissue held therebetween. At least one of the jaw members includes a cutting slot defined along a length thereof which is dimensioned to reciprocate a cutting instrument therealong for cutting tissue disposed between jaw members. An actuator advances the cutting instrument from a first position wherein the cutting instrument is disposed proximal to tissue held between the jaw members to at least one subsequent position wherein the cutting instrument is disposed distal to tissue held between the jaw members.

International Classification:
A61B 18/14
US Classification:
606 51, 606 52
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.

US Classification:
295921, 29825, 29874, 29876, 606 49, 606 30, 606 51
Abstract:
A method for manufacturing an end effector assembly for sealing tissue includes the initial step of providing first and second electrically conductive sealing plates. The method also includes the steps of: encasing at least one of the electrically conductive sealing plates in a substantially moldable insulative material; applying a load to the electrically conductive sealing plates; allowing the insulative material to deform to create a gap between the sealing plates between about 0. 001 inches to about 0. 010 inches; and allowing the insulative material to cure.
