Title: SURGICAL INSTRUMENT WITH LOCKING ARTICULATION DRIVE WHEEL
Abstract:
A surgical instrument (210) includes a shaft assembly (212) and an articulation control assembly (218). The shaft assembly (212) includes an articulation section (130) that is configured to deflect a distal end portion from the longitudinal axis. The articulation control assembly (218) includes an articulation control member (222) and a transmission assembly (226, 426, 726). The articulation control member (222) is rotatably mounted relative to the shaft assembly (212, 214, 216, 30, 712). The transmission assembly (226) is operatively connected between the articulation control member (222) and the articulation section (130) of the shaft assembly (212). The transmission assembly (226) is configured to transmit selective manipulation of the articulation control member (222) to the articulation section (130) and selectively actuate the articulation section (130). The articulation control assembly (218) is configured to lock without selective manipulation of the articulation control member (222) to thereby inhibit actuation of the articulation section (130) and unlock with selective manipulation of the articulation control member (222) to thereby actuate the articulation section (130).
