1. A surgical system comprising:
a device having a device housing, an elongated shaft extending distally from the device housing, a proximal first opening at a back end of the device housing and a second opening in the device housing configured to receive a power pack, the device housing configured to be mounted to a robot arm for robotic manipulation of the device housing such that the device housing can be moved to various positions by the robot arm;
a removable loading unit; and
a power pack configured for removable loading into the second opening of the device for powering the device, the power pack having a power pack housing having a first motor, a first motor shaft, a rotatable member, a first drive mechanism, and a first engagement member configured for removable engagement with a first axially movable member of the loading unit when the power pack is loaded into the device, the power pack effecting movement of the first axially movable member from a first position to a second position to actuate the device independent of the robot arm, wherein the device is movable to different orientations by the robot arm grasping the device;
the removable loading unit having an elongated member and first and second jaws at a distal portion, the first jaw supporting a plurality of surgical fasteners, the loading unit configured for insertion through the first opening at the back end of the device housing and in a distal direction through a lumen in the device housing and a lumen in the elongated shaft of the device, the loading unit further configured for removal in a proximal direction retracted though the lumen in the device housing and out the first opening at the back end of the device housing, the loading unit configured for removal without removing the device from the body;
wherein the loading unit has an opening configured to receive the first engagement member of the power pack for moving the first axially movable member.
