The NorthStar Beach Chair positioner provides unparalleled speed and flexibility in shoulder cases.  The chair rapidly attaches to standard OR tables via a simple clamping mechanism that engages attachment rails, and within minutes, is ready for a case.  The device is totally passive (no electricity required) and relies on a pneumatic cylinder that provides continuous adjustment angles and a rigid lock to the desired position.  Once secured to the surgical table, the chair allows access to either shoulder in a variety of combinations.
