An electromechanical surgical device is provided and includes an end effector configured to perform at least one function; and a shaft assembly. The end effector includes a rotatable drive screw having a coupling member at a proximal end thereof; and a flexible drive cable rotatably supported therein and extending therefrom, wherein the flexible drive cable receives rotational forces and transmits said rotational forces to the drive screw to actuate the end effector. The shaft assembly includes a proximal neck housing supported at a distal end of the outer tube; and a distal neck housing pivotally connected to the proximal neck housing, wherein a distal end of the distal neck housing is configured and adapted for operative connection with the end effector. In use, when the end effector is connected to the shaft assembly, the flexible drive cable extends through the proximal neck housing and the distal neck housing.
