Filed:

Aug 26, 2009

Appl. No.:

12/548031

Inventors:

Peter M. Mueller - Frederick CO, US
Sara E. Anderson - Erie CO, US

Assignee:

TYCO Healthcare Group LP - Mansfield MA

International Classification:

A61B 18/12

US Classification:

606 51, 606 46

Abstract:

The present disclosure relates to an end effector assembly for use with a forceps. The end effector assembly includes a pair of jaw members and a cutting element. The pair of jaw members having at least one jaw member that is moveable relative to the other from a first, open position to a second, closed position for grasping tissue. Each of the jaw members includes a cutting channel that is defined therein and extends therealong. The cutting element includes a fixed end and a movable end. The fixed end is disposed within the cutting channel of one of the jaw members and the moveable end is disposed within the cutting channel of the other of the jaw member. The cutting element defines a movable cutting loop disposed between the cutting channels and between the fixed end and the movable end. The cutting loop has an arcuate portion that is reciprocatable to cut tissue.

International Classification:

A61B 18/14

US Classification:

606 45

Abstract:

An end effector assembly includes opposed jaws moveable from an open to a closed position for grasping tissue therebetween. Each jaw includes an electrically conductive surface adapted to conduct electrosurgical energy through tissue disposed between the jaws. A static bipolar cutting portion including at least one electrically conductive cutting element and at least one insulating element having a first configuration is disposed on at least one of the jaws. The static cutting portion is configured to electrically cut tissue disposed between the jaws upon activation of the cutting element and at least one of an opposing sealing surface and an opposing cutting element. A dynamic cutting portion including at least one electrically conductive cutting element and at least one insulating element having a second configuration is disposed on at least one of the jaws. The dynamic cutting portion electrically transects tissue during movement relative to tissue.

Assignee:

TYCO Healthcare Group LP - Boulder CO

International Classification:

A61B 17/28

US Classification:

606205

Abstract:

An end effector of a forceps includes first and second jaw members movable between spaced-apart and approximated positions for grasping tissue. Each jaw member includes a tissue sealing plate that is selectively energizable. The tissue sealing plates are configured to conduct energy therebetween and though tissue to seal tissue. A knife includes a distal surface and an upper surface. The knife is selectively translatable between a retracted position and an extended position wherein the knife extends between the jaw members. The distal surface is configured for dynamic tissue cutting upon translation of the knife from the retracted to the extended position. The upper surface is configured for static tissue cutting with the knife in the extended position. The knife is selectively energizable and is configured to conduct energy between the knife and one or both of the tissue sealing plates and through tissue to electrically cut tissue.
