A hand-held electromechanical surgical device is provided and configured to selectively connect with a surgical accessory. The surgical device includes a device housing defining a connecting portion for selectively receiving a coupling assembly of the surgical accessory. The connecting portion includes an annular wall defining a cylindrical recess dimensioned to receive the coupling assembly of the surgical accessory; a collar slidably supported about the annular wall, wherein the collar is slidable between a first position and a second position; and at least one socket member interposed between the annular wall and the collar, wherein each socket member is slidably supported in the annular wall. Each socket member includes a first fixed state wherein each socket member projects into the cylindrical recess of the annular wall; and a second movable state wherein each socket member is free to not project into the cylindrical recess of the annular wall.

1. A hand-held electromechanical surgical device configured to selectively connect with a surgical accessory, wherein the surgical accessory includes a cylindrical coupling assembly defining an annular groove formed in an outer surface thereof, the electromechanical surgical device, comprising: a device housing defining a connecting portion for selectively receiving the coupling assembly of the surgical accessory, the connecting portion includes: an annular wall defining a cylindrical recess dimensioned to receive the coupling assembly of the surgical accessory;a collar slidably supported about the annular wall, wherein the collar is slidable between a first position and a second position; andat least one socket member interposed between the annular wall and the collar, wherein each socket member is slidably supported in the annular wall, and wherein each socket member includes: a first fixed state wherein each socket member projects into the cylindrical recess of the annular wall; anda second movable state wherein each socket member is free to not project into the cylindrical recess of the annular wall;wherein, when the collar is in the first position, the collar acts on each socket member to maintain each socket in the first state; andwherein, when the collar is in the second position, each socket member is free to move to the second state, wherein the collar includes a discrete camming ring located along an inner surface thereof, wherein the discrete camming ring acts on each socket member when the collar is in the first position. 2. The electromechanical surgical device according to claim 1, wherein the collar is spring biased to the first position. 3. The electromechanical surgical device according to claim 1, wherein each socket member is in registration with the annular groove of the surgical accessory when the surgical accessory is connected to the electromechanical surgical device. 4. The electromechanical surgical device according to claim 3, wherein each socket member at least partially enters the annular groove of the surgical accessory when the surgical accessory is connected to the electromechanical surgical device and when the collar is in the first position. 5. The electromechanical surgical device according to claim 4, wherein when the surgical accessory is connected to the electromechanical surgical device, and when the collar is in the first position, the surgical accessory is prevented from disconnection from the electromechanical surgical device. 6. The electromechanical surgical device according to claim 1, wherein the surgical accessory is connectable to the electromechanical surgical device when the collar is in the second position. 7. The electromechanical surgical device according to claim 1, wherein the surgical accessory is not connectable to the electromechanical surgical device when the collar is in the first position. 8. The electromechanical surgical device according to claim 1, wherein the surgical accessory is inhibited from disconnection from the electromechanical surgical device when the surgical accessory is connected to the electromechanical surgical device and when the collar is in the first position. 9. The electromechanical surgical device according to claim 1, wherein the first position of the collar is a distally advanced position. 10. The electromechanical surgical device according to claim 1, wherein the second position of the collar is a proximally retracted position. 11. The electromechanical surgical device according to claim 1, wherein the at least one socket member includes three socket members radially evenly spaced around the annular wall of the connecting portion. 12. The electromechanical surgical device according to claim 1, wherein the connecting portion further includes an alignment nub projecting radially into the cylindrical recess, wherein the alignment nub is dimensioned to enter an alignment slot provided on an outer surface of the cylindrical coupling assembly of the surgical accessory. 13. The electromechanical surgical device according to claim 1, wherein the discrete camming ring is secured to the inner surface thereof.
