1. An indicator mechanism for a surgical instrument, the indicator mechanism comprising:
a base;
an aperture defined in the base;
a rotatable driver disk coupled to the base, wherein the rotatable driver disk is configured to be driven by a motorized actuation force;
a visual indicator coupled to the rotatable driver disk, the visual indicator being visible through the aperture; and
a detent mechanism configured to hold the rotatable driver disk in differing rotational positions, the detent mechanism comprising:
one or more first detent features on an elastically deflectable member coupled to the rotatable driver disk, and
one or more second detent features on the base and configured to engage the one or more first detent features, wherein engagement of the one or more first detent features with the one or more second detent features holds the rotatable driver disk in respective rotational positions of the differing rotational positions.
