Coupling assembly for interconnecting an adapter assembly and a surgical device, and surgical systems thereof

An electromechanical surgical system, comprising:

• a hand-held electromechanical surgical device configured to actuate a surgical attachment, the surgical device including:
• a housing;
• and
• at least one rotatable drive shaft supported in the housing for driving actuation of the surgical attachment, the at least one rotatable drive shaft of the surgical device defining a longitudinal axis;
• an adapter assembly for selective interconnection between the surgical device and the surgical attachment, the adapter assembly including at least one rotatable drive shaft configured to transmit/convert a rotational force of the at least one rotatable drive shaft of the surgical device into an axial/rotative force for actuating the surgical attachment;
• and
• a coupling assembly for coupling the surgical device to the adapter assembly, the coupling assembly including:
• a first connector configured for mating engagement with the surgical device;
• a second connector configured for mating engagement with the adapter assembly;
• an outer tube having a first end and a second end defining a longitudinal axis therebetween, the first end of the outer tube supporting the first connector and the second end of the outer tube supporting the second connector, wherein the longitudinal axis of the coupling assembly extends transversely relative to the longitudinal axis of the surgical device;
• and
• at least one drive shaft disposed within the outer tube, the at least one drive shaft of the coupling assembly being configured to rotate relative to the outer tube to transfer rotational motion of the at least one rotatable drive shaft of the surgical device to the at least one rotatable drive shaft of the adapter assembly.

A coupling assembly for selectively interconnecting a surgical device with an adapter assembly that is configured for connection with a surgical attachment, the coupling assembly comprising:

• a first connector configured for mating engagement with a surgical device and including at least one gear shaft configured for connection with at least one rotatable drive shaft of the surgical device;
• a first gear disposed adjacent the first connector and configured for operable connection with the at least one gear shaft of the first connector;
• a second connector configured for mating engagement with an adapter assembly and including at least one gear shaft configured for connection with at least one rotatable drive shaft of an adapter assembly;
• a second gear disposed adjacent the second connector and configured for operable connection with the at least one gear shaft of the second connector;
• an outer tube having a first end and a second end defining a longitudinal axis therebetween, the first end of the outer tube supporting the first connector and the second end of the outer tube supporting the second connector, wherein the longitudinal axis of the outer tube extends transversely relative to a longitudinal axis defined by the surgical device;
• and
• at least one rotatable drive shaft disposed within the outer tube, the at least one rotatable drive shaft of the coupling assembly supporting the first and second gears such that rotation of the at least one rotatable drive shaft of the surgical device results in rotation of the at least one rotatable drive shaft of the adapter assembly via the at least one rotatable drive shaft of the coupling assembly.
