Abstract
Devices and methods for articulating a distal end of a surgical device are provided. In one exemplary embodiment, the device includes an articulation joint that includes both an inner guide and an outer sleeve. The inner guide includes one channel extending therethrough that receives both a cutting mechanism and a closure band. Further, an outer surface of the inner guide, in conjunction with the outer sleeve, can define two additional channels that each receive an articulation band for articulating an end effector coupled to the articulation joint. The outer surface of the inner guide can include a plurality of ribs that also help define the two additional channels. Further, the outer sleeve can include a plurality of slots formed in it to improve flexibility and stability. Additional configurations of articulation joints, and configurations of components of a surgical device, are also provided, as are methods for using the same.
