ELECTROSURGICAL INSTRUMENT JAW STRUCTURE WITH CUTTING TIP

摘要

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.
