    Abstract: A minimally invasive surgical instrument includes a first mechanism including a periphery and an opening in the periphery, a second mechanism including a surface and a helical slot in the surface, a pin extending through the opening of the first mechanism and into the helical slot of the second mechanism, and a surgical device coupled to an end of the first mechanism. A first axial axis of rotation is defined for the first mechanism. A second axial axis of rotation is defined for the second mechanism. The second axial axis of rotation is coincident with the first axial axis of rotation. Rotation of the first mechanism relative to the second mechanism results in motion of the second mechanism along the second axial access of rotation relative to the first mechanism.

    Abstract: A device includes a first mechanism having a surface and a helical slot in the surface, a second mechanism having a periphery and an axial slot in the periphery, and an insert comprising a pin. The second mechanism is located within the first mechanism. The insert is located within the second mechanism. The pin extends from the insert through the axial slot of the second mechanism and into the helical slot of the first mechanism. The insert is configured to couple to an instrument. In some embodiments, the insert is configured to move the instrument in a degree of freedom in response to the second mechanism being held stationary and the first mechanism being rotated. In some embodiments, the degree of freedom is an insertion and retraction degree of freedom.
