1. Carefully inspect the SP Cannula visually for damage. Examples of damage include nicks
or dents in the edge of the SP Cannula tube, and dents or flat spots in the SP Cannula
tube that interfere with the free insertion of the Entry Guide.
Figure 9.5 shows examples
of SP Cannula damage and a SP Cannula that is not damaged.
Figure 9.5 Visual inspection examples
Note: Image magnification and special lighting were used in order to capture the
images above. However, SP Cannula and obturator defects can be seen under
normal lighting conditions with the naked eye.
CAUTION: Do not use an obturator with visible cracks or other damage.
2. Insert the obturator into the SP Cannula to inspect the inner diameter of the SP Cannula
(
Figure 9.6 A and B). If the obturator cannot be inserted smoothly through the SP
Cannula, use a new SP Cannula.
Figure 9.6 Insert the obturator (A) until it is fully inserted (B)
3. After the obturator inserts all the way, spin the obturator relative to the SP Cannula.
Ensure that the obturator can make one complete revolution freely. Use
Table 9-2 for
pass/fail criteria when inspecting SP Cannulas.
4. Remove the obturator.
