摘要： An end-effector configured to grasp tissue is disclosed herein. The end-effector includes an ultrasonic blade configured to transfer ultrasonic energy to the tissue and a clamp arm. The clamp arm includes a clamp arm pad including an electrically conductive material and an electrically non-conductive material. The clamp arm pad is configured as an electrode of a radiofrequency energy circuit, wherein the electrode is configured to transfer radiofrequency energy through the tissue to a return electrode of the radiofrequency energy circuit, and wherein the electrically non-conductive material is configured to reduce the possibility of an electrical short between the electrically conductive material and the ultrasonic blade as the clamp arm pad degrades throughout the usable life of the end effector.

摘要： An end-effector and a surgical instrument including the end-effector are disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and to electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw, a cantilever electrode configured to electrically couple to an opposite pole of the electrical generator and an electrically non-conductive clamp arm pad including a plurality of teeth. The surgical instrument includes a control circuit to detect a distal conductive element contact with the ultrasonic blade and adjust power applied to the ultrasonic blade based on detection of the contact.

摘要： An end-effector is disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw and an electrode configured to electrically couple to an opposite pole of the electrical generator. In one configuration, the electrode is segmented. In another configuration, the ultrasonic blade includes electrically insulative material deposited on selected areas to prevent electrical shorting in the event of the ultrasonic blade contacts the electrode. In another configuration, the clamp arm, the ultrasonic blade, or both include selectively coated components.

摘要： An end-effector is disclosed including an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and electrically couple to a pole of an electrical generator and a clamp arm including a clamp jaw and a cantilever electrode fixed to the clamp jaw. The cantilever electrode is configured to electrically couple to an opposite pole of the electrical generator. The clamp arm may include an I-beam shaped clamp arm pad and the cantilever electrode is disposed between the I-beam. The clamp jaw, the cantilever electrode, and the clamp arm pad may define recesses along a length coinciding with the ultrasonic blade. The clamp arm pad may be fixed to the clamp jaw and disposed between the clamp jaw and the cantilever electrode and may extend beyond the surface of the cantilever electrode. The clamp arm may include a stationary gap setting pad and movable floating gap setting pads.

The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and to electrically couple to a pole of an electrical generator. The clamp arm includes a clamp jaw, a plurality of variable longitudinal support elements, and a cantilever electrode configured to electrically couple to an opposite pole of the electrical generator, the cantilever electrode fixed to the clamp jaw at a proximal end and free to deflect at a distal end. The cantilever electrode is supported by the variable longitudinal support elements. The variable longitudinal support elements apply a variable force on the cantilever electrode from the proximal end to the distal end.
