具有双模式端部执行器和侧装夹持臂组件的外科器械
摘要：
本发明提供了一种外科器械，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的电连续性。
摘要（英）：

A surgical instrument includes a body, an ultrasonic blade, a clamp arm assembly, and a detent assembly. The clamp arm assembly includes a clamp arm pivotably coupled with the body at a pivot assembly. The clamp arm is operable to compress tissue against the ultrasonic blade. The detent assembly is configured to provide tactile resistance to pivotal movement of the clamp arm relative to the body beyond a predefined pivot angle. The detent assembly is configured to permit pivotal movement of the clamp arm relative to the body beyond a predefined pivot angle upon application of a force sufficient to overcome the tactile resistance
