Abstract: An instrument includes a shaft, a moveable component coupled to the shaft, and an actuation member drive assembly coupled to the shaft. The actuation member drive assembly may include a rotatable drive member, a ring gear operably coupled to the rotatable drive member and configured to rotate in response to rotation of the rotatable drive member, and a planet gear meshed with the ring gear. The instrument further includes an actuation member extending through the shaft and operably coupled to the moveable component and the planet gear. The actuation member is moveable in translation in response to rotation of the planet gear. Devices and methods relate to actuation member drive assemblies.
