Figure 5. Hold setscrew connector block between thumb and two fingers.
6. Using the torque wrench, loosen the setscrew in the setscrew connector
block by turning the wrench counterclockwise (approximately one turn)
(Figure 6).
Note: Ensure the torque wrench is perpendicular to the setscrew
surface while loosening the setscrew.
Cautions:
▪
Ensure the torque wrench is perpendicular to the setscrew
surface while loosening the setscrew. Failure to hold the
wrench perpendicular while loosening the setscrew may result
in damage to the lead, resulting in intermittent or loss of
stimulation.
▪
Hold the setscrew connector block firmly between thumb and
two fingers to support the lead body and prevent rotation.
Failure to properly prevent rotation may break or damage the
lead, and may require lead replacement.
7. Stabilize the lead and gently remove the lead from the setscrew
connector block (Figure 7).
Caution: If resistance is felt while removing the lead from the lead
cap, loosen the setscrew slightly to ensure that it clears the lead
contact. Avoid disengaging the setscrew. Inspect the lead for
damage (flattening or stretching of the lead) if resistance was felt
prior to removal, which would require surgical replacement.
