Abstract

A surgical apparatus including an electrical conductor with a strain relief is provided. A tool assembly is supported on a body portion and is articulable relative to the body portion. The tool assembly includes an identification assembly in electrical communication with a powered handle assembly. An electrical conductor extends from a connection assembly in the body portion to the identification assembly. The electrical conductor includes a strain relief portion for accommodating the articulation of the tool assembly relative to the body portion.

Claims

1. A surgical apparatus comprising:

a body portion having a proximal end and a distal end and including a connection assembly supported on the proximal end;

a tool assembly supported on a distal end of the body portion and being articulable relative to the body portion, the tool assembly including an identification assembly; and

an electrical conductor extending from the connection assembly to the identification assembly, the electrical conductor including a strain relief portion configured to accommodate articulation of the tool assembly relative to the body portion.

2. The surgical apparatus of claim 1, wherein the strain relief portion includes a plurality of coils.

3. The surgical apparatus of claim 2, wherein a height of the plurality of coils decreases from a proximal portion of the plurality of coils to a distal portion of the plurality of coils.

4. The surgical apparatus of claim 2, wherein a height of the plurality of coils is uniform from a proximal portion of the plurality of coils to a distal portion.

5. The surgical apparatus of claim 2, wherein the plurality of coils are equally spaced relative to each other.

6. The surgical apparatus of claim 1, wherein the body portion defines a channel for receiving the electrical conductor.

7. The surgical apparatus of claim 1, wherein the channel includes a central portion for receiving the strain relief portion of the electrical conductor.

8. The surgical apparatus of claim 1, wherein the surgical apparatus includes a powered handle assembly, the electrical conductor electrically coupling the identification assembly to the handle assembly.

9. The surgical apparatus of claim 1, wherein the tool assembly includes a stapling assembly.

10. The surgical apparatus of claim 9, wherein the stapling assembly includes a removable cartridge assembly.

11. The surgical apparatus of claim 1, wherein the electrical conductor includes a flexible cable.

12. The surgical apparatus of claim 11, wherein the flexible cable includes a proximal portion and a distal portion, the proximal portion being axially affixed to the body portion.

13. The surgical apparatus of claim 1, wherein the electrical conductor is axially affixed to the body portion using adhesive.

14. The surgical apparatus of claim 1, wherein the strain relief portion is configured to permit lengthening of the electrical conductor.

15. The surgical apparatus of claim 1, wherein the strain relief portion is configured to permit shortening of the electrical conductor.

16. The surgical apparatus of claim 1, wherein the body portion, the tool assembly, and the electrical conductor are formed as a loading unit which is configured to be releasably coupled to a powered handle assembly.

17. The surgical apparatus of claim 16, wherein the loading unit includes a jaw member and a cartridge assembly selectively receivable within the jaw member.

18. The surgical apparatus of claim 17, wherein the identification assembly includes a connector assembly disposed within the jaw member and a chip assembly disposed within the cartridge assembly.

19. The surgical apparatus of claim 18, wherein loading of the cartridge assembly within the jaw member engages the chip assembly with the connector assembly.

20. The surgical apparatus of claim 1, wherein the electrical conductor includes a connector member integrally formed on a proximal end thereof.

21. The surgical apparatus of claim 1, wherein the electrical conductor includes a stiffened portion attached to the electrical conductor.
