    • A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.
    • 灵活的内窥镜施夹器包括具有联接到一端的手动致动器的柔性线圈和联接到另一端的钳口组件。 夹子存放在邻近夹爪组件的位置,夹子推动器邻近夹子存放设置。 致动器包括用于打开和关闭夹爪的杆,用于旋转夹爪组件的旋钮和用于分配夹子的曲柄。 旋钮和杠杆联接到单个控制构件,该单个控制构件延伸穿过线圈到接合器,在该接合器处,接合到耦合到钳口的一对牵引线。 曲柄联接到沿着远端部分螺纹的第二控制构件。 螺纹部分接合推动器附近的螺纹构件并且联接到推动器,使得螺纹控制构件通过曲柄的旋转使得推动器向远侧移动。
