摘要:
A surgical instrument includes a shaft assembly and an articulation control assembly. The shaft assembly includes an articulation section. The distal end of the shaft assembly is configured to receive an end effector. The articulation section is configured to deflect the end effector from the longitudinal axis. The articulation control assembly includes a first articulation control member, a second articulation control member, and a transmission assembly. The transmission assembly includes a high ratio drive and a low ratio drive. The high ratio drive is configured to drive the articulation section to deflect the end effector at a high rate of articulation in response to actuation of the first articulation control member. The low ratio drive is configured to drive the articulation section to deflect the end effector at a low rate of articulation in response to actuation of the second articulation control member.
