    摘要: A surgical instrument includes a drive housing, a spline, a carriage, an elongate shaft assembly, an end effector, and an activating mechanism. The spline includes a drive gear rotatable via the spline. The shaft assembly extends along a longitudinal axis from the carriage. The shaft assembly includes a wrist disposed between the end effector and a distal end of the shaft assembly. The activating mechanism includes a barrel cam extending along a rotational axis and having a first cam profile radially extending about the rotational axis. The barrel cam is operatively coupled to the drive gear such that rotation of the drive gear is configured to actuate the activating mechanism to move at least a portion of the end effector or the shaft assembly. The first cam profile defines a lock zone configured to selectively lock movement of the portion of the end effector or the shaft assembly.

    摘要: A sphincter augmentation device includes a plurality of interlinked bodies and a pair of device ends configured to releasably couple together to secure the bodies in a loop formation sized to fit around an internal anatomical passageway of a patient. The device further includes a plurality of resilient members, with each resilient member extending between an adjacent pair of the bodies. The resilient members are configured to elastically deform to permit the device to transition between a radially contracted state and a radially expanded state. The resilient members bias the device toward the radially contracted state in which the device exerts an inwardly directed force on the anatomical passageway to selectively limit passage of fluids therethrough. The device further includes an expansion limiting member that extends between and is slidably received by an adjacent pair of the bodies, and is configured to limit radial expansion of the device.
