Flexible shaft extender and method of using same
View Patent ↗An extender for use in an electro-mechanical surgical system includes a surgical attachment that may be detachably coupled to an electro-mechanical driver device via a flexible shaft. The extender is a substantially rigid extender that includes a proximal end that may be detachably coupled to a distal end of the flexible shaft. The extender also includes a distal end that may be detachably coupled to the surgical attachment. The extender also includes at least one rotatable drive shaft configured to engage and be secured with a respective rotatable drive shaft of the flexible shaft such that rotation of the respective rotatable drive shaft of the flexible shaft by the electro-mechanical driver device causes the at least one rotatable drive shaft of the extender to rotate, thereby rotating a complementary connector of the surgical attachment so as to operate the surgical attachment.
1. A surgical extender for selectively interconnecting a surgical attachment and at least one drive member of an electro-mechanical driver device of an electro-mechanical surgical system, the extender comprising:
a handle;
a substantially rigid tube coupled to the handle;
a first coupling disposed on the handle, the first coupling being configured for detachable coupling to a coupling of the electro-mechanical driver device for providing operative connection to the at least one drive member of the electro-mechanical driver device, the first coupling including an integral electrical connector for connection with an electrical connector of the electro-mechanical driver device;
a second coupling disposed at a free end of the rigid tube, the second coupling being configured for detachable coupling to a coupling of the surgical attachment; and
at least two rotatable shafts disposed within the rigid tube, each rotatable shaft being configured to engage and be secured with a respective rotatable drive member of the electro-mechanical driver device such that rotation of the respective rotatable drive members by the electro-mechanical driver device causes the 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 extender of claim 1 , further comprising a wiring harness assembly disposed within the first coupling, the wiring harness including the integral electrical connector, and a memory unit.
3. The extender of claim 2 , wherein the memory unit is configured to store one or more of serial number data, an attachment type identifier data and a usage data.
4. The extender of claim 3 , wherein one or more of the serial number data and the identifier data is configured as read-only data.
5. The extender of claim 4 , wherein the serial number data is data uniquely identifying the extender.
6. The extender of claim 5 , wherein the identifier data is data identifying the type of the extender of a plurality of diverse and unique extenders.
7. The extender of claim 3 , wherein the usage data represents a number of times the extender has been used.
8. The extender of claim 3 , wherein the wiring harness assembly further includes a data cable configured to transfer data between the memory unit and the electro-mechanical driver device.
9. The extender of claim 1 , wherein the wiring harness assembly further includes a data cable configured to transfer data between a memory unit located in the surgical attachment and the electro-mechanical driver device.
10. The extender of claim 1 , wherein the first coupling of the handle is opposite the rigid tube.
11. An electro-mechanical surgical system, comprising:
an electro-mechanical driver device including at least one rotatable drive member and a coupling associated with the at least one rotatable drive member;
a surgical attachment configured to perform a surgical function, the surgical attachment including a coupling for receiving an operative force from the electro-mechanical driver device; and
a substantially rigid extender for electromechanically selectively interconnecting the surgical attachment and the at least one rotatable drive member of the electro-mechanical driver device, the extender including:
a handle;
a substantially rigid tube coupled to and extending from the handle;
a first coupling disposed on the handle, the first coupling being configured for detachable coupling to the coupling of the electro-mechanical driver device for providing operative connection to the at least one drive member of the electro-mechanical driver device, the first coupling including an integral electrical connector for connection with an electrical connector of the electro-mechanical driver device;
a second coupling disposed at a free end of the rigid tube, the second coupling
being configured for detachable coupling to a coupling of the surgical attachment; and
at least two rotatable shafts disposed within the rigid tube, each rotatable shaft being configured to engage and be secured with a respective rotatable drive member of the electro-mechanical driver device such that rotation of the respective rotatable drive members by the electro-mechanical driver device causes the 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.
12. The electro-mechanical surgical system of claim 11 , wherein the extender further comprises a wiring harness assembly disposed within the first coupling, the wiring harness assembly including the integral electrical connector, and a memory unit.
13. The electro-mechanical surgical system of claim 12 , wherein the memory unit of the extender is configured to store one or more of serial number data, an attachment type identifier data and a usage data.
14. The electro-mechanical surgical system of claim 12 , wherein the wiring harness assembly of the extender further comprises a data cable configured to transfer data between the memory unit and the electro-mechanical driver device.
15. The electro-mechanical surgical system of claim 11 , wherein the wiring harness assembly of the extender further comprises a data cable configured to transfer data between a memory unit located in the surgical attachment and the electro-mechanical driver device.
16. The electro-mechanical surgical system of claim 11 , wherein the surgical attachment is a surgical stapler-cutter.
17. The electro-mechanical surgical system of claim 11 , wherein the first coupling of the handle of the extender is opposite the rigid tube.
