Abstract
An endoscopic surgical instrument has a distal end configured to perform an action on tissue; a proximal end; a beam; a drive rod; and at least one rail supporting at least one bearing, the at least one bearing movable relative to the at least one rail. The distal end of the instrument is configured to receive at least a portion of the beam, the beam movable longitudinally in response to an action on the drive rod. The at least one rail is shaped and configured to contact the beam tangentially to prevent the beam from buckling as the beam is moved longitudinally.
