A single use integrated disposable rotational speed reduction assembly having a shaft assembly, a housing, a planet carrier having a gear with inward-facing gear teeth, and one or more internal gear components with gear teeth. The shaft assembly causes rotation of the planet carrier with a sun gear via engagement with the internal gear components. The rotation of the internal gear components causes rotation of the planet carrier, with a reduction of rotational speed relative to the rotation of the shaft assembly. One or more gear components can be configured to fail after a predetermined number of use cycles.
