Abstract

A bipolar electrosurgical instrument has a pair of pivotable juxtaposed jaw members and a locking mechanism operatively associated with a second of the jaw members. The locking mechanism has a first position engaged with the second jaw member for preventing movement of the second jaw member between an axially aligned orientation and at least one angled orientation, and a second position. The second position is disengaged from the second jaw member allowing for movement of the second jaw member between the axially aligned orientation and the at least one angled orientation. The instrument has an actuation mechanism operatively connected to a first of the jaw members with the actuation mechanism operable to move the first jaw member between an axially aligned first orientation and at least one angled orientation. An articulation knob is operatively associated with the locking mechanism and effectuates independent operation of the locking and actuation mechanisms.
