    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.

    摘要翻译： 端部执行器包括具有第一特定声阻抗值的第一部分和具有小于第一特定声阻抗值的第二特定声阻抗值的第二部分。 第一部分包括末端执行器的近端段和端部执行器的远端段，并且近端段和远端段由第一材料组成。 第二部分包括由第二材料构成的端部执行器的插入段。 插入段沿着端部执行器的纵向轴线位于近端段和远端段之间。 插入段用于桥接或填充节点能隙。 手术器械包括被构造成沿着纵轴产生作为预定频率的振动的换能器。 超声波刀片沿着耦合到换能器的纵向轴线延伸。 插入片段或衬垫位于与刀片相邻的位置，使得当外科器械处于关闭位置时它与刀片接合并产生填充节点能隙的热量。
