1. An adapter assembly for selectively interconnecting an end effector to a handle assembly supporting a motor, the motor configured to impart drive force from the handle assembly to the end effector to operate the end effector, the adapter assembly comprising:
a proximal housing body configured to couple to the handle assembly;
a distal housing body coupled to the proximal housing body;
an outer tube extending distally from the distal housing body and configured to support the end effector on a distal end portion of the outer tube; and
a cable drive assembly supported between the proximal and distal housing bodies and including:
a body portion having an upper portion and a lower portion;
a first cable gear assembly supported on the upper portion of the body portion and supporting a first cable;
a second cable gear assembly supported on the lower portion of the body portion and supporting a second cable; and
a plurality of guide pulleys supported between the body portion and the distal housing body, the plurality of guide pulleys configured to guide the first cable and the second cable through the distal housing body and into the outer tube for operating the end effector.
