Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A cooler has front, rear, end and bottom walls. The walls form an interior chamber. The interior chamber has an upper ledge, a lower ledge and an intermediate ledge. A lower tray is positionable upon the lower ledge. Slots extend through the lower tray and are adapted to support ice. An intermediate tray is positionable upon the intermediate ledge. A plurality of apertures extend through the intermediate tray. The apertures are adapted to removable support food containers. A lid is positionable upon the upper ledge for securement and thermal insulating purposes.
