ELECTROSURGICAL INSTRUMENT JAW STRUCTURE WITH CUTTING TIP
First Claim
1. An electrosurgical instrument for scoring, welding, and transecting tissue, the electrosurgical instrument comprising:
- first and second openable-closeable jaws, the first and second openable-closeable jaws comprising first and second conductive tissue engaging surfaces, respectively, and first and second insulating members, respectively; and
at least one scoring electrode extending from a distal end of at least one of the first and second openable-closeable jaws, the scoring electrode coupled with at least one of the first and second insulating members.

Abstract
An electrosurgical instrument for scoring, welding and transecting tissue is provided. The electrosurgical instrument comprises first and second openable-closeable jaws and at least one scoring electrode extending from a distal end of at least one of the first and second openable-closeable jaws. The first and second openable-closeable jaws comprises first and second conductive tissue engaging surfaces, respectively, and first and second insulating members, respectively. The scoring electrode is coupled with at least one of the first and second insulating members. The at least one scoring electrode can be activated independently from the first and second openable-closeable jaws so that the electrosurgical instrument can independent score tissue and weld tissue.

21. A method for scoring, welding, and transecting a target tissue volume using a electrosurgical jaw, the method comprising:
-
scoring a tissue structure adjacent the target tissue volume with a scoring electrode extending distally from at least one of a first openable-closeable jaw and a second openable-closeable jaw; clamping the target tissue volume between a first tissue engaging surface and a second tissue engaging surface of the first openable-closeable jaw and second openable-closeable jaw, respectively; delivering RF energy to the target tissue volume to weld at least a portion of the target tissue volume. - View Dependent Claims (22, 23, 24, 25)
