1. A gear roll mechanism for a medical device, comprising:
a first gear, a second gear, and a third gear, wherein:
the first gear is a compressible gear,
the first gear comprises a first contact portion, a second contact portion, and a first rotational axis, the first contact portion and the second contact portion of the first gear are rotatable about the first rotational axis,
the second gear comprises a second gear contact portion and a second rotational axis, the second gear contact portion is rotatable about the second rotational axis,
the third gear comprises a third gear contact portion and a third rotational axis, the third gear contact portion is rotatable about the third rotational axis,
in a first rotational orientation, the first contact portion of the first gear is meshed with the second gear contact portion, the first contact portion of the first gear is compressed towards the first rotational axis and is spaced from the first rotational axis a first radial distance,
in a second rotational orientation, the first contact portion of the first gear is not meshed with the second gear contact portion, the first contact portion of the first gear is spaced from the first rotational axis a second radial distance,
in a third rotational orientation, the second contact portion of the first gear is meshed with the third gear contact portion, the second contact portion of the first gear is compressed towards the first rotational axis and is spaced from the first rotational axis a third radial distance,
in a fourth rotational orientation, the second contact portion of the first gear is not meshed with the third gear contact portion, the second contact portion of the first gear is spaced from the first rotational axis a fourth radial distance,
the second radial distance is greater than the first radial distance, and
the fourth radial distance is greater than the first radial distance.
