An instrument includes a shaft, a movable 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 planetary gear engaged with the ring gear. The instrument further includes an actuation member extending through the shaft and operably coupled to the movable component and the planetary gear. The actuation member is translationally movable in response to rotation of the planetary gear. The devices and methods involve an actuating member drive assembly. 一种器械包括轴、联接到所述轴的可移动部件以及联接到所述轴的致动构件驱动组件。该致动构件驱动组件可包括可旋转驱动构件、可操作地联接到所述可旋转驱动构件并被构造成响应于所述可旋转驱动构件的旋转而旋转的环形齿轮以及与所述环形齿轮啮合的行星齿轮。所述器械进一步包括致动构件，该致动构件延伸穿过所述轴并且可操作地联接到所述可移动部件和所述行星齿轮。所述致动构件可响应于所述行星齿轮的旋转而平移移动。所述装置和方法涉及致动构件驱动组件。
