Articulation joint with bending member

摘要

The present disclosure provides an articulation joint that can include a plurality of articulation links, wherein each articulation link can include an elongate body having a proximal end, a distal end, an outer surface, and a first lumen extending from the proximal end to the distal end. Each articulation link can further include a plurality of arms extending radially outward from the elongate body, wherein each arm includes an inner end attached to the outer surface of the elongate body and a second lumen extending from a proximal side of the arm to a distal side of the arm. The articulation joint can also include a bending member positioned within the first lumen of the elongate body and a control member positioned within a plurality of second lumens, wherein each of the plurality of second lumens includes a common longitudinal axis.
