ABSTRACT:
An articulation mechanism for use with a surgical instrument includes a shaft, a first member disposed in mechanical cooperation with the articulation shaft, a second member disposed in mechanical cooperation with the shaft, and a flexible shaft having proximal and distal portions. The flexible member is operatively coupled to the first and second members. Upon rotation of the articulation shaft, at least one of the first and the second members moves longitudinally with respect to the other of the first and second members between a first position where the first and second members are approximated to each other and a second position where the first and second members are spaced apart from each other. This longitudinal motion causes the distal portion of the flexible member to articulate relative to the proximal portion.
