摘要：
A surgical apparatus includes a body assembly a shaft an acoustic waveguide an articulation section an end effector and a rigidizing member. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide includes a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section includes a first member and a second member. The second member is longitudinally translatable relative to the first member. The end effector includes an ultrasonic blade in acoustic communication with the waveguide. The rigidizing member is configured to selectively engage at least a portion of the articulation section to thereby selectively provide rigidity to the articulation section.
