ELECTROSURGICAL DEVICE HAVING CONTROLLABLE CURRENT PATHS

摘要

An electrosurgical instrument. The electrosurgical instrument includes an end effector movable between a first position and a second position, a first jaw member which includes first and second electrically conductive members, and a second jaw member which includes a third electrically conductive member. The first jaw member is movable relative to the second jaw member from an open position to a closed position to grasp a tissue positioned between the first and second jaw members. At least one of the first and second jaw members is adapted to connect to an electrosurgical energy source such that electrosurgical energy can be selectively communicated through the tissue positioned between the first and second jaw members to effect a tissue seal. A distance between the first electrically conductive member and the third electrically conductive member is less than a distance between the second electrically conductive member and the third electrically conductive member.
