1. An assembly comprising:
an axle having an axis of rotation, wherein rotation of the axle about the axis of rotation causes deflection of a portion of a medical device;
a collet having an opening, wherein the axle extends through the opening; and
an actuator configured to interact with the collet, wherein the actuator includes a lever extending radially outward from an outer surface of the actuator and a protrusion extending radially inward from an inner surface of the actuator, toward the axis of rotation;
wherein a first configuration of the collet permits rotation of the axle relative to the collet and a second configuration of the collet inhibits rotation of the axle relative to the collet, wherein, in the second configuration, the actuator is rotated relative to the collet such that the protrusion of the actuator contacts the collet and applies a radially inward force on the collet, toward the axis of rotation, to move a portion of the collet radially inward toward the axis of rotation, and wherein rotation of the actuator relative to the collet transitions the collet from the first configuration to the second configuration.
