    • A rotatable surgical instrument for use alone or in conjunction with other instruments such as an endoscope. The instrument, having a proximal end and a distal end, includes a proximal actuator assembly, a distal end effector assembly having a surgical tool and a first rotational engagement member, a hollow member extending between the actuator and the end effector assembly, and a control member extending through the hollow member. The control member has a proximal end connected to the actuator assembly, a distal end connected to the end effector assembly, and a second rotational engagement member. In operation, actuation of the actuator assembly causes the control member to actuate the surgical tool, and the first engagement member engages the second engagement member to transmit torque applied to the control member to the end effector assembly.
    • 一种可旋转的手术器械,可单独使用或与其他仪器如内窥镜一起使用。 具有近端和远端的仪器包括近端致动器组件,具有手术工具和第一旋转接合构件的远端执行器组件,在致动器和端部执行器组件之间延伸的中空构件,以及控制器 构件延伸穿过中空构件。 控制构件具有连接到致动器组件的近端,连接到端部执行器组件的远端和第二旋转接合构件。 在操作中,致动器组件的致动使得控制构件致动外科手术工具,并且第一接合构件接合第二接合构件以将施加到控制构件的扭矩传递到端部执行器组件。

    • A variably flexible insertion device includes a hollow body having a proximal end with an entrance for receiving an instrument and a distal end with a tip for protrusion of the instrument. A device transitions the hollow body between a relatively flexible condition and a relatively stiff condition. Tendons within the hollow body maintain the hollow body in the relatively flexible and relatively stiff conditions. A method for variably flexing an insertion device for receiving an instrument, includes providing a hollow body having inner and outer sleeves defining a space therebetween in which tendons are disposed. Suction is applied to create a vacuum in the space for frictionally locking the tendons in place between the sleeves in a relatively stiff condition of the hollow body. The vacuum is relieved to release the tendons in a relatively flexible condition of the hollow body.
    • 可变弹性插入装置包括具有近端的中空本体,其具有用于容纳器械的入口和具有用于突出仪器的尖端的远端。 一种装置在相对柔性的状态和较硬的状态之间转变中空体。 中空体内的肌腱将中空体保持在相对柔韧和相对僵硬的状态。 一种用于可变地弯曲用于接收器械的插入装置的方法,包括提供具有限定其间布置有腱的空间的内部和外部套筒的中空本体。 施加抽吸以在空间中产生真空,以在中空体的相对刚硬的状态下将钢筋摩擦锁定在套筒之间的适当位置。 真空被释放以在中空体的相对柔性的状态下释放腱。
