    摘要： The present disclosure relates to electrosurgical instruments for use in sealing various tissues. The instrument includes a housing having a shaft attached thereto and an end effector assembly attached to a distal end of the shaft, wherein the end effector assembly includes first and second jaw members attached thereto. The jaw members are movable relative to one another from a first position for approximating tissue to at least one additional position for grasping tissue therebetween. The jaw members have an elastomeric material disposed on an inner facing tissue contacting surface thereof with the elastomeric materials including an electrode disposed therein. The electrodes are offset a distance X relative to one another such that when the jaw members are closed about the tissue and when the electrodes are activated, electrosurgical energy flows through the tissue in a generally coplanar manner relative to the tissue contacting surfaces.

    摘要： 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.
