An exemplary surgical stapler may include a staple holder; an anvil movably connected to the staple holder; staple forming pockets defined in a surface of the anvil; and a staple trap movable within the anvil relative to the staple forming pockets. Users can install the decorative lighting either a single time or few times, and thereafter manipulate a plurality of predetermined color schemes using a pre-programmed control panel. According to the invention, this is achieved by the parts to be joined being positioned one over the other and connected to each other by forming a force of adhesion and by the parts to be joined being arranged in such a way that they are tilted at a predetermined tilting angle with respect to the normal plane, at least during the melting of the solder paste. The location computing unit is configured to compute a start point of the changed display area when the display area is changed. The assembly further comprises a blade shroud covering at least a portion of the blade body and securable to the shroud retainer element and at least one of the socket and the blade body. The coupling unit selectively closes, and in this manner provides a mechanical coupling, only if both coupling windings are no longer supplied with electrical energy.
