摘要： An articulation mechanism for a surgical instrument includes an articulation assembly, a plurality of cables, and a trigger. The cables are coupled to the articulation assembly at a proximal end thereof and extend distally therefrom. The cables are configured to engage an end effector assembly of the surgical instrument at a distal end thereof. The trigger is coupled to the articulation assembly and is selectively moveable from a shipping position to a use position. In the shipping position, the cables are substantially un-tensioned. In the use position, the cables are disposed in an initial tensioned position. In the use position, the trigger is moveable between an unlocked position and a locked position. In the unlocked position, the cables are selectively tensionable to articulate the end effector assembly. In the locked position, the tensions on the cables are maintained to lock the end effector assembly in position.

摘要翻译： 用于外科器械的关节运动机构包括铰接组件，多个电缆和触发器。 电缆在其近端处联接到关节运动组件并从其向远侧延伸。 电缆被配置成在外科器械的远端接合手术器械的末端执行器组件。 触发器联接到关节运动组件，并且可选择性地从运输位置移动到使用位置。 在运输位置，电缆基本上未张紧。 在使用位置，电缆被设置在初始张紧位置。 在使用位置，触发器可在解锁位置和锁定位置之间移动。 在解锁位置，电缆可选择性地张紧以使端部执行器组件铰接。 在锁定位置，维持电缆上的张力，以将端部执行器组件锁定就位。
