1. An electromechanical surgical system, comprising:

  • a hand-held surgical device, including;

    a device housing defining a connecting portion;

    at least one drive motor supported in the device housing and being configured to rotate a first drive shaft of the surgical device;

    a battery disposed within the device housing for powering the at least one drive motor; and

    a circuit board disposed within the device housing for controlling power delivered from the battery to at least one drive motor;

    an end effector configured to perform at least one function, the end effector including at least one axially translatable drive member; and

    an adapter assembly for selectively interconnecting the end effector and the surgical device, the adapter assembly including;

    an adapter housing configured and adapted for selective connection to the connecting portion of the surgical device and to be in operative communication with the first drive shaft of the surgical device;

    an outer tube having a proximal end supported by the adapter housing and a distal end configured and adapted for connection with the end effector, wherein the distal end of the outer tube is in operative communication with each of the at least one axially translatable drive member of the end effector; and

    a first drive converter assembly including;

    a first distal drive shaft rotatably supported in the adapter housing, wherein a proximal end of the first distal drive shaft is connectable to the first drive shaft of the surgical device;

    a drive coupling nut threadably connected to a threaded distal portion of the first distal drive shaft, wherein the drive coupling nut is keyed against rotation within the adapter housing; and

    a drive tube having proximal end connected to the drive coupling nut and the distal end configured for selective engagement with the at least one axially translatable drive member of the end effector;

    wherein rotation of the first drive shaft of the surgical device results in rotation of the first distal drive shaft, and wherein rotation of the first distal drive shaft results in axial translation of the drive coupling nut, the drive tube and the at least on axially translatable drive member of the end effector.
