  • Patent number: 10595870
    Abstract: An anvil assembly includes a retaining member having a body portion and a frangible portion connected to the body portion, where the frangible portion is positioned to engage a backup member and separates from the body portion during movement of the backup member from a first, proximal position to a second, distal position. The retaining member keeps the backup plate in the proximal position prior to firing of the stapling assembly, and upon separation of the frangible portion allows the backup plate to move to the distal position during firing of the stapling assembly. Proximal force on the backup plate after firing of the stapling assembly is avoided, thereby helping to ensure titling of the anvil assembly.

    Abstract: A circular stapling device includes a reload and an elongate body or adaptor. The reload includes a staple pusher assembly, a knife carrier, and an annular knife supported on the knife carrier. The adaptor includes a pusher drive member and a knife carrier pusher having at least one resilient finger that is deformable inwardly towards the knife carrier into releasable engagement with the knife carrier to releasably couple the knife carrier to the knife carrier pusher. In a pre-fired state, the pusher is positioned to retain the resilient finger in the deformed state to prevent separation of the knife carrier pusher and the knife carrier. After the stapling device is fired and the knife carrier is advanced and subsequently retracted, the resilient finger of the knife carrier pusher is positioned to flex outwardly from the deformed state to automatically uncouple the knife carrier pusher from the knife carrier.

The adapter includes a movable extension link that pivots on a proximal end, due to the action of an air cylinder actuator, and that pivoting motion causes an anvil mounted on its distal end to grasp the opposite (bottom) side of the workpiece, while also positioning the anvil to a location where it intercepts the nail that will be fired through the workpiece by the nailer tool. The anvil mechanism rotates from a “relaxed” position that fits within a gap in the boards of a workpiece, to an actuated “ready” position that receives and curls the nail, for clenching a multi-substrate workpiece. The actuations are automatically sequenced, in one embodiment.

    Abstract: A flat clinch assembly fits upon or within a base of a stapling device. The assembly preferably includes a slot with extended resiliently biased arms or toggles, where a rest position has the arms at or near a level of a working surface. An ejecting staple deflects and energizes the arms to cause the arms to rotate and create a clearance recess whereby points of the staple legs slide inward along the anvil. A restorative bias acting on the arms causes the arms to rebound to a rest position and to bend the legs upward. The legs thereby are normally pressed flat against the back sheet of a paper stack at the working surface. The arms or toggles are lightweight whereby the inertia of a fast moving staple moves the arms or toggles.

  • Patent number: 8261957
    Abstract: Immediately after a clinch lever causes a clinch link to clinch the leg of a staple which penetrates sheets of paper to be stapled, a pressure by the clinch lever with respect to the clincher link is temporarily reduced by a pressure reducing unit. Therefore, a clincher moves down in a state where the clincher still receives the press-contacting force from a driver plate. Accordingly, the looseness occurs between the driver plate and the clincher link. A fixing plate becomes easy to draw out as much as the looseness. If the fixing plate is set to be drawn out at this timing, it can be simply drawn out to be moved to the initial position.

  • Publication number: 20110062210
    Abstract: A stapler comprises a mechanism to first fully drive staples into sheets of materials, e.g., paper, and only then to fold over the legs of the staples. This results in a flat clinch and very few crumpled staples. An anvil table is locked in a raised position above a staple anvil, and a trigger mechanism will operate only when a staple blade has proceeded through a staple magazine and forced a staple fully out. The trigger mechanism slides back when this happens, and unlocks the anvil table so it can drop down around a staple-leg-folding anvil. The whole top of the stapler and the papers being stapled drop with the already fully inserted staple onto the anvil to fold the staple legs over flat.

  • Patent number: 7900804
    Abstract: A forming plate and a driver plate are held at a front portion of a path of supplying connected staples in a laminated state. A staple in a C-shape formed at an inside of a strike out path formed between a front end face of a supply path and a back face of the face plate arranged on a front side of the supply path is pressed to supply to inside of the strike out path toward the face plate by a pusher urged by a spring. The staple is struck out by the driver plate. The pusher is made to constitute a first pusher, and a second pusher for pressing a leg portion of the staple to the face plate is aligned to be arranged to a side of a staple strike out port of the first pusher.

  • Publication number: 20110017799
    Abstract: A staple pocket arrangement on the anvil portion of a surgical stapler device includes pairs of staple pockets corresponding to each one of a plurality of staples to be closed. The staple pockets may have a generally triangular shape when viewed from above. Each respective staple leg is received at a longitudinal end of the staple pocket that provides a relatively wide target area for receiving the staple leg to eliminate or at least minimize the likelihood that a staple leg will miss the staple pocket due to, e.g., misalignment between a first jaw of the surgical stapler having the anvil and a second jaw of the surgical stapler having a cartridge configured to fire the staples. The staple pockets may be arranged in rows, each row of staple pockets being longitudinally offset from another row, such that each staple pocket in a first row of staple pockets is nested with a staple pocket from an adjacent row of staple pockets to make more efficient use of space on the anvil.
