Flexible shaft extender and method of using same

1. An electro-mechanical surgical system, comprising:

an electro-mechanical driver device including a flexible shaft including a pair of rotatable drive members extending along a length thereof; and

an extender having:

a proximal end including a handle having a handle cap assembly configured to detachably couple to a distal end of the flexible shaft, the handle cap assembly including:

a handle cap including at least two orifices;

a key plate; and

a quick connect collar mounted to a proximal end of the handle cap and retained thereagainst by the key plate; and

a distal end configured to be detachably coupled to a proximal end of a surgical attachment,

wherein each orifice of the at least two orifices is configured to engage and rotatably secure to a corresponding one of the pair of rotatable drive members of the electro-mechanical driver device such that rotation of the pair of rotatable drive members causes at least two rotatable shafts of the extender to rotate thereby transmitting a force to the surgical attachment so as to operate the surgical attachment.

2. The electro-mechanical surgical system of claim 1 , wherein the handle cap has at least one aperture at the proximal end thereof.

3. The electro-mechanical surgical system of claim 2 , wherein a distal end of the key plate seats within the at least one aperture at the proximal end of the handle cap.

4. The electro-mechanical surgical system of claim 1 , wherein the quick connect collar is configured to facilitate coupling and uncoupling the extender to the distal end of the flexible shaft.

5. The electro-mechanical surgical system of claim 1 , wherein the key plate includes a corresponding pair of orifices that align with the at least two orifices of the handle cap.

6. The electro-mechanical surgical system of claim 1 , further comprising a pair of drive sockets, each drive socket of the pair of drive sockets being rotatably retained within a corresponding one of the at least two orifices of the handle cap.

7. The electro-mechanical surgical system of claim 6 , wherein each drive socket of the pair of drive sockets have mounted thereon:

a bearing spacer,

a sealing element and

a bearing, wherein the bearing spacer, the sealing element, and the bearing are configured to rotatably retain each drive socket of the pair of drive sockets in the corresponding one of the at least two orifices of the handle cap.

8. The electro-mechanical surgical system of claim 7 , wherein the sealing element of each drive socket of the pair of drive sockets and seal elements provided at the distal end of the extender prevent moisture from entering the extender to allow sterilization of the extender via an autoclave.

9. The electro-mechanical surgical system of claim 1 , wherein the key plate includes at least one aperture defined therethrough that is configured to provide access for a wiring harness retained within the handle cap assembly.

10. The electro-mechanical surgical system of claim 9 , wherein a proximal end of the wiring harness is accessible through the at least one aperture defined through the key plate and includes a connector for connection to a data transfer cable of the flexible shaft.

11. The electro-mechanical surgical system of claim 10 , wherein a distal end of the wiring harness extends out of the distal end of the extender for communicating data from the surgical attachment to the data transfer cable of the flexible shaft.

12. The electro-mechanical surgical system of claim 1 , wherein the surgical attachment is a surgical stapler-cutter.

13. The electro-mechanical surgical system of claim 1 , wherein the extender is flexible.

14. An electro-mechanical surgical system, comprising:

an electro-mechanical driver device including a pair of rotatable drive members projecting from a distal end thereof;

an extender having:

a proximal end including a handle having a handle cap assembly configured to detachably couple to the distal end of the electro-mechanical driver device, the handle cap assembly including:

at least two orifices, each orifice of the at least two orifices configured to engage and rotatably secure to a corresponding one of the pair of rotatable drive members of the electro-mechanical driver device; and

a pair of drive sockets, wherein each drive socket of the pair of drive sockets is rotatably retained within a corresponding one of the at least two orifices of the handle cap assembly, each drive socket of the pair of drive sockets having mounted thereon:

a bearing spacer;

a sealing element; and

a bearing, wherein the bearing spacer, the sealing element, and the bearing are configured to rotatably retain each drive socket of the pair of drive sockets in the corresponding one of the at least two orifices; and

a distal end configured to be detachably coupled to a proximal end of a surgical attachment, wherein a rotation of either of the pair of rotatable drive members causes a corresponding one of a pair of rotatable shafts of the extender to rotate thereby transmitting a force to the surgical attachment so as to operate the surgical attachment.

15. The electro-mechanical surgical system of claim 14 , wherein the pair of shafts of the extender are rotatable shafts.

16. The electro-mechanical surgical system of claim 14 , wherein the sealing element of each drive socket of the pair of drive sockets and seal elements provided at the distal end of the extender prevent moisture from entering the extender to allow sterilization of the extender via an autoclave.

17. The electro-mechanical surgical system of claim 14 , wherein the surgical attachment is a surgical stapler-cutter.
