Surgical apparatus with conductor strain relief
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.
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 adjust in length 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.
