Fine adjustments are made by turning the Drive Screw in each clamp using the Clamp Driver Tool
The Fixation Clamp is designed to allow several clamps to move independently along the rail to provide the versatility of applying several points of compression and/or distraction along the same rail.
The Clamp Driver Tool (Single) engages one clamp only - providing movement while others remain stationary. The clamp is able to travel in either direction along the rail.
The Clamp Driver Tool (Multiple) engages each clamp through which it passes - providing coordinated, unified movement to those clamps to apply compression or distraction. The clamps are able to travel in either direction along the rail.
