摘要：
Abstract various example embodiments described herein are directed to articulating surgical instruments for treating tissue comprising an end effector and a shaft extending proximally from the end effector along the longitudinal axis.In certain embodiments, the shaft comprises a plurality of transverse spacer members as well as the first and second rotatable members extending through at least a portion of the plurality of transverse spacer members.The first and second rotatable members may both be biased away from the longitudinal axis such that their respective directions of bias vary with rotation of the first rotatable member. When the respective directions of bias of the first and second rotatable members oppose one another, the shaft may be substantially straight.When the respective directions of bias of the first and second rotatable members are aligned with one another, the shaft may articulate away from the longitudinal axis in the direction of the alignment. Translation of the summary summary invention patent: "surgical instruments with stems of articulation ".They are described in this invention to various methods that are directed to surgical instruments articulantes for treatment of tissue includes an actuator end and a rod that extends from the actuator at proximal end along an axis longitudi Nal.In certain methods, the rod comprises a plurality of members transverse spacers and first and second rotary members that extend through at least a portion of the plurality of transverse spacer members.The first and second members pivoting may be oriented in the opposite direction to the longitudinal axis so that their directions of orientation varies with the rotation of the first member rotates. When the respective directions of orientation of the first and second members rotatable opposed, the shaft may be substantially linear.When the respective directions of orientation of the first and second rotary members are aligned with each other, the stem can articu
