    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: A composite end effector for an ultrasonic surgical instrument is provided and includes a first portion formed from a first material that exhibits a first characteristic value when excited by an ultrasonic energy input and a second portion formed from a second material that exhibits a second characteristic value when excited by the ultrasonic energy input. The composite end effector exhibits a composite characteristic value different from the first and second characteristic values when excited by the ultrasonic energy input.

    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: Various embodiments are directed to a surgical instrument comprising, a shaft, and an end effector. The shaft may be coupled to the handle and may extend distally along a longitudinal axis. The end effector may be positioned at a distal end of the shaft and may comprise first and second jaw members and a reciprocating member. The first and second jaw members may define first and second longitudinal slots. The reciprocating member may be translatable distally and proximally parallel to the longitudinal axis and through the first and second longitudinal slots. A distal portion of the reciprocating member may define a blade. The end effector may additionally comprise a first push rod member having a distally directed end pivotably coupled to the first jaw member and a proximally directed end pivotably coupled to the shaft at a first pivot point as well as a first linkage member having a distally directed end pivotably coupled to the first jaw member and a proximally directed end pivotably coupled to a second pivot point. In this way, distal motion of the reciprocating member may exert a force on the first and second jaw members causing the first and second jaw members to translate towards one another in a substantially parallel motion.
