Rod Crimping Pliers for USS Implants

Using the Rod Introduction Pliers (Persuader)

The Persuader is used in situations when the distance 
between implant and rod is significant. The Persuader 
permits introduction of the 6 mm rod into the side 
opening of the implant.

The Persuader is also used when applying the segmental 
derotation technique for scoliosis correction.

Option:

Alternative method without Persuader

If the rod is aligned horizontally to the side opening, the 
rod crimping pliers can be used to push the rod into the 
implant opening.
