    摘要： An end effector for use with an ultrasonic surgical instrument. A body extends along a longitudinal axis. The body includes a proximal end and a distal end. The proximal end of the body is configured to couple to an ultrasonic transducer configured to produce vibrations at a predetermined frequency. A folded element includes a first end coupled to the distal end of the body at a predetermined region between a node and an antinode. The folded element extends along the longitudinal axis from the distal end to the proximal end of the body. The folded element comprises a second free acoustic end. A distal portion of the body and the folded element define a parallel acoustic path.

    摘要： An end effector includes a first portion having a first specific acoustic impedance value, and a second portion having a second specific acoustic impedance value less than the first specific acoustic impedance value. The first portion includes a proximal end segment of the end effector and a distal end segment of the end effector, and the proximal end segment and the distal end segment are composed of a first material. The second portion includes an insert segment of the end effector composed of a second material. The insert segment is located between the proximal end segment and the distal end segment along the longitudinal axis of the end effector. The insert segment functions to bridge or fill the nodal energy gap. A surgical instrument includes a transducer configured to produce vibrations along a longitudinal axis as a predetermined frequency. An ultrasonic blade extends along the longitudinal axis coupled to the transducer. An insert segment or a pad is positioned adjacent to the blade such that it engages the blade when the surgical instrument is in a closed position and generates heat filling the nodal energy gap.

    摘要： An ultrasonic surgical system includes an ultrasonic transmission member having a proximal end and a distal end. An ultrasonically actuated end-effector is attached at the distal end of the transmission member. A pressurized fluid delivery system includes a fluid nozzle in communication with at least one fluid source. The fluid nozzle is arranged and configured to deliver pressurized fluid to soft tissue at a rate to move the soft tissue away from the end-effector during use.
