1. A prosthetic thumb device comprising:
a track configured to attach to a prosthetic socket;
a carriage comprising:
a first component that couples to the track such that the carriage is operable to move along the track; and
a second component that is configured to couple with a prosthetic digit, rotate with respect to the first component, and remain in fixed position with respect to the first component as the first component moves along the track; and
a locking mechanism coupled to the carriage and comprising an actuator; wherein:
the locking mechanism is configured to:
in a first state, prevent the carriage from moving along the track in a first direction; and
in a second state, allow the carriage to move along the track in the first direction; and
the actuator, when pushed by a user, causes the locking mechanism to transition from the first state to the second state.
