    摘要: An apparatus includes a body, an end effector, an articulation section, and a shaft assembly coupling the body with the end effector. The shaft assembly includes a sheath, a first monolithic articulation connector, and a second monolithic articulation connector. The first monolithic articulation connector includes a first distal portion and a first proximal portion. The first distal portion and the first proximal portion consist of a homogenous continuum of material. The first distal portion is configured to flex relative to the first proximal portion. The first distal portion is at least partially housed within the sheath. The second monolithic articulation connector is at least partially housed within the sheath. The first and second monolithic articulation connectors are configured to longitudinally translate in opposing directions relative to the sheath to deflect the articulation section and the end effector relative to the longitudinal axis of the sheath.

    摘要: An apparatus includes a body, a shaft assembly, an articulation section, an end effector, an articulation connector, and an articulation drive assembly. The shaft assembly extends distally from the body. The end effector is connected to the articulation section such that the end effector is configured to deflect relative to the longitudinal axis of the shaft assembly. The articulation connector is configured to translate relative to the shaft assembly to deflect the end effector relative to the longitudinal axis. The articulation drive assembly is configured to translate the articulation connector relative to the shaft assembly. The articulation drive assembly includes a rotatable housing and a first lead screw assembly. The first lead screw assembly includes a first half and a second half. The first lead screw assembly is slidably coupled with the shaft assembly and is configured to translate in response to rotation of the rotatable housing.
