Summary:Disclosed embodiments include apparatuses, systems, and methods for guiding a rotatable actuator along a helical path with a varied pitch to motivate an attached implement. In an illustrative embodiment, an apparatus includes an elongated implement movable along an axis and a rotatable actuator operably coupled with a proximal end of the implement to motivate the implement to move along the axis in response to rotation of the rotatable actuator. A guide is operably coupled with rotatable actuator, where the guide defines a generally helical channel around the axis to direct movement of a rotatable actuator, and wherein a pitch of the helical channel is varied to reduce a distance of travel of the actuator along the axis per unit of rotation of the actuator.
