Abstract

An extender for use in an electro-mechanical surgical system that 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. The extender may include a memory unit and a data cable that transfers data from the memory unit to an electro-mechanical driver device. Additionally or alternatively, the extender may include a data cable that transfers data from a memory unit in the surgical attachment to the electro-mechanical driver device. Advantageously, the extender is autoclavable.

Claims

1. An electro-mechanical surgical system including a surgical attachment detachably coupleable to at least one drive member of an electro-mechanical driver device, the electro-mechanical surgical system further including a substantially rigid extender comprising:

a handle having a proximal end and a distal end;

a substantially rigid tube coupled to the distal end of the handle;

a proximal coupling disposed at the proximal end of the handle and being configured to be detachably coupled to a coupling providing operative connection to at least one drive member of the electro-mechanical driver device;

a distal coupling disposed at the distal end of the tube and being configured to be detachably coupled to a proximal coupling of the surgical attachment; and

at least two rotatable shafts disposed within the extender, 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 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 ID 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 4, wherein the ID data is data identifying the type of the extender.

7. The extender of claim 4, wherein the usage data represents a number of times the extender has been used.

8. The extender of claim 2, further comprising a data cable configured to transfer data between the memory unit and the electromechanical driver device.

9. The extender of claim 1, wherein 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.

10. An electro-mechanical surgical system, comprising:

an electro-mechanical driver device including at least one rotatable drive member;

a surgical attachment detachably coupleable to the electro-mechanical driver device; and

a substantially rigid extender comprising;

a handle having a proximal end and a distal end;

a substantially rigid tube coupled to the distal end of the handle;

a proximal coupling disposed at the proximal end of the handle and being configured to be detachably coupled to a coupling providing operative connection to the at least one drive member of the electro-mechanical driver device;

a distal coupling disposed at the distal end of the tube and being configured to be detachably coupled to a proximal coupling of the surgical attachment; and

at least two rotatable shafts disposed within the extender, 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.

11. The electro-mechanical surgical system of claim 10, wherein the extender further comprises a memory unit.

12. The electro-mechanical surgical system of claim 11, wherein the memory unit is configured to store one or more of serial number data, an attachment type identifier data and a usage data.

13. The electro-mechanical surgical system of claim 11, wherein the extender further comprises a data cable configured to transfer data between the memory unit and the electromechanical driver device.

14. The electro-mechanical surgical system of claim 10, wherein 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.

15. The electro-mechanical surgical system of claim 10, wherein the surgical attachment is a surgical stapler-cutter.
