Zusammenfassung:Disclosed is a surgical instrument with a handle and elongate shaft assembly extending distally from the handle. The elongate shaft assembly has a longitudinal axis and is able to articulate between a fully flexed configuration and a lesser flexed configuration. The elongated shaft assembly includes a first tubular member having a first flexible portion with a first preferential bending direction. The elongated shaft assembly also includes a second member including a second flexible portion axially fixed to the first tubular member at a position distal from the first flexible portion. The first flexible portion is defined by a plurality of cutouts, each cutout defining a cutout longitudinal axis transverse the shaft longitudinal axis and wherein the plurality of radial cutouts have an asymmetrical shape about the cutout longitudinal axis.
