    • A biopsy instrument and method of using such are provided wherein the biopsy instrument includes a proximal actuation handle, an elongate flexible member, and a distal assembly. The flexible member, connected to and extending from the actuation handle, includes an aspiration conduit for fluid connection with a vacuum source and for permitting the flow of fluid from the distal end to the proximal end of the biopsy instrument. The flexible member may include an irrigation conduit for supplying irrigation fluid to the distal end. The actuation handle includes a stationary member and an actuation device, and may include a sample chamber, a sample collector, valves for regulating the vacuum in the aspiration conduit and the fluid flow in the irrigation conduit, and a pressure increasing device for selectively increasing the pressure of the fluid supplied to the distal end. The distal assembly, coupled to the distal end of the flexible member, may be comprised of a movable jaw and a stationary jaw, or of first and second movable jaws. With the jaws in a closed position, the distal assembly may provide a substantially fluidtight passageway at the distal end of the aspiration conduit. The movable jaws are coupled to the actuation device, such that actuation of the actuation handle moves the movable jaws relative to the flexible member, thereby opening and closing the distal assembly.
    • 提供活检器械及其使用方法,其中活检器械包括近端致动手柄,细长柔性构件和远端组件。 连接到致动手柄并从致动手柄延伸的柔性构件包括用于与真空源流体连接并用于允许流体从活组织检查仪器的远端到近端的流动的抽吸导管。 柔性构件可以包括用于向远端供应冲洗流体的冲洗管道。 致动手柄包括固定构件和致动装置,并且可以包括样品室,样品收集器,用于调节抽吸导管中真空的阀和冲洗导管中的流体流;以及增压装置,用于选择性地增加 供给到远端的流体的压力。 耦合到柔性构件的远端的远端组件可以包括可移动钳口和固定钳口,或第一和第二可移动钳口。 当钳口处于关闭位置时,远端组件可以在抽吸导管的远端提供基本上流体密封的通道。 可动夹爪联接到致动装置,使得致动手柄的致动相对于柔性构件移动可动爪,由此打开和关闭远端组件。

    • 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。
