  • Publication number: 20130030438
    Abstract: A new shape changing staple and instrument for the fixation of structures to include bone tissue and industrial materials. This new staple stores elastic mechanical energy to exert force on fixated structures to enhance their security and in bone affect its healing response. This staple once placed changes shape in response to geometric changes in the materials structure, including healing bone tissue. The staple is advanced over prior staples due to its: 1) method of operation, 2) high strength, 3) method of insertion, 4) compressive force temperature independence, 5) energy storing staple retention and delivery system, 6) compatibility with reusable or single use product configuration, 7) efficient and cost effective manufacturing methods, and 8) reduction in the steps required to place the device. In addition to the staple's industrial application an embodiment for use in the fixation of the musculoskeletal system is shown with staple, cartridge, and extrusion handle.

  • Patent number: 7870716
    Abstract: A pocket-sizing apparatus for a device that inserts staple drivers into pockets aligned to form a slot in a surgical staple cartridge. A fin extends from a driver guide fixture for insertion into the slot. The fin increases the size of the slot, thereby aiding in inserting drivers into the pockets. Preferably a second fin extends from the driver guide fixture adjacent the fixture passage and aligned with the first fin. A gap is formed between the first and second fins, extending from a first edge to an opposite edge of the fixture passage. The driver is driven through the gap. The fins are substantially equal to the thickness of the driver. The fins have tapered leading edges to aid cartridge insertion and removal, and a lip extends from the driver guide fixture for preventing the fins from widening the slot too much and for narrowing an overly wide slot.

  • Patent number: 7207168
    Abstract: An improved method and apparatus for inserting surgical staple drivers into a cartridge, including a base, a cartridge-receiving plate having a channel, upper and lower degating plates having a passage through them, a knife with a sharp edge adjacent the passage and a plunger apparatus that drives the drivers downwardly through the guide passage and into pockets in the cartridge. A cartridge locator plate seats the cartridge against stops in the channel. The cartridge-receiving plate is adjustable relative to the base. The upper and lower degating plates and the knife are not adjustable relative to the base, which avoids the need for re-alignment of the knife and degating plates upon re-mounting on the base. The cartridge-receiving plate is aligned relative to the base. A top riser is adjustably mounted to the base, and a cylinder arm, which holds the plunging apparatus, is non-adjustably mounted to the top riser.

  • Patent number: 5360305
    Abstract: A clinch type staple has a U-shaped configuration with a pair of legs extending generally perpendicularly from a base portion of the staple with the outside surfaces of the distal ends of the legs being bevelled. The legs of the staple lie in spaced apart planes that are parallel to one another, but are angularly offset from one another in order to insure that the legs will not contact or interfere with each other as they are clinched into a workpiece. A plurality of such clinch staples can be manufactured into an assembly of clinch staples. The method of making such an assembly of clinch staples includes advancing a plurality of wires in parallel side-by-side relation in a flat planar array and adhering the wires to one another. A blank, severed from an end of the formed array, includes a plurality of side-by-side wire segments of equal length extending parallel to one another in a first direction.
