357.372 Impactor for Helical Blade for TFN
357.377 Connecting Screw for Helical Blade for TFN
Insert the cannulated helical blade connecting screw into the
impactor for helical blade. Select the appropriate length
11.0 mm helical blade as measured. Align the back end of
the helical blade with the impactor. Thread the connecting
screw into the helical blade and finger-tighten the assembly.
Pass the helical blade insertion assembly through the blade
guide sleeve. Align the pins on the impactor with the
grooves in the blade guide sleeve. They will only align in one
orientation, which is indicated when the gold pin on the
back of the impactor is positioned toward the patient’s head.
Hold the gold handle of the inserter and advance the blade
as far as possible by hand. Use light hammer blows on the
back of the connecting screw to seat the helical blade. Insert
to the stop. The blade is fully inserted when the helical blade
impactor comes to a stop at the back of the blade guide
sleeve.
The helical blade MUST be fully inserted.
