Provided is a surgical instrument. The surgical instrument includes a body, an ultrasonic blade, a clamp arm, and a resilient member. The body includes an electrical conductor and defines a longitudinal axis. The clamp arm is pivotably coupled with the body at a pivot assembly. The clamp arm is operable to compress tissue against the ultrasonic blade. The clamp arm includes an electrode operable to apply RF energy to tissue, wherein the clamp arm is configured to be loaded onto and removed from the body at the pivot assembly along a path that is transverse to the longitudinal axis defined by the body. The resilient member is located within the pivot assembly. The resilient member is configured to provide electrical continuity between the electrode of the clamp arm and the electrical conductor of the body. 本发明提供了种外科器械，所述外科器械包括主体、超声刀、夹持臂和弹性构件。主体包括电导体并且限定纵向轴线。夹持臂以能够枢转的方式在枢转组件处与主体联接。夹持臂能够操作以将组织压靠在超声刀上。夹持臂包括能够操作以将RF能量施加到组织的电极，其中夹持臂被构造成能够沿着横向于由主体限定的纵向轴线的路径在枢转组件处被装载到主体上以及从主体移除。弹性构件位于枢转组件内。弹性构件被构造成能够提供夹持臂的电极与主体的电导体之间
