Abstract: A surgical instrument can comprise an end effector including a plurality of jaws which can be configured to compress tissue therebetween. The end effector can further comprise one or more electrodes which can be configured to direct a flow of electrical current through the tissue in order to heat the tissue and denature collagen and/or other proteins within the tissue. As the tissue cools, the collagen and/or other proteins can renature and thereby seal the tissue. In certain embodiments, the end effector of the surgical instrument can further comprise movable portions which can apply a tension force to the tissue surrounding the tissue being sealed. In various circumstances, the tension force can reduce the over-denaturation, shrinkage, and/or other damage to the surrounding tissue caused by heat flowing from the end effector during the sealing process.

Abstract: The limbs of a bipolar forceps for RF coagulation are produced from a bimetal material, wherein an outer layer (18) consists of stainless steel and determines the mechanical properties of the forceps, while an inner layer (20) consists of a sliver alloy.

The inner layer (20) brings about good heat dissipation from the electrodes (30) and prevents the tissue from sticking thereto during coagulation.

Abstract: An end effector comprises a first jaw, a second jaw, a firing beam, and a lockout feature. The second jaw pivots relative to the first jaw from an open position to a closed position. The firing beam has a sharp distal end and translates between the first and second jaws.

The end effector applies bipolar RF energy when the firing beam is in the first distal position. The firing beam then translates to a second distal position to sever tissue captured between the first and second jaws. The lockout feature prevents the firing beam from advancing from the first distal position to the second distal position until the lockout feature is actuated.
