Title: ARTICULATION DRIVE FEATURE IN SURGICAL INSTRUMENT
Abstract:
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 potion. 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.
