摘要：
A surgical instrument including a shaft including a distal portion and an articulatable portion is disclosed. The articulatable portion, positioned proximal to the distal portion, includes a plurality of joint members. A first articulation cable extends through each first channel of each of the plurality of joint members and a second articulation cable extends through each second channel of each of the plurality of joint members to the distal portion. The first and second articulation cables are transitionable between: (i) an unlocked state, where the first and second articulation cables are free to translate distally and proximally and the plurality of joint members are slidable relative to one another to pivot the distal portion away from a longitudinal axis, and (ii) a locked state, where translation of the first and second articulation cables is locked, causing a position of the distal portion relative to the longitudinal axis to be locked.
