  • Patent number: 8789736
    Abstract: A stapling element is provided, operative to pierce and penetrate a tissue by a first end, and close around the tissue. Three factors help prevent local necrosis: 1. The self-closing feature of the staple does not lead to tissue crushing. 2. Edge seams are applied generally perpendicular to the tissue edge, allowing for blood supply to the tissue edge. 3. Excess tissue is cut off at the seam, minimizing the amount of tissue that may undergo local necrosis. A physical feature prevents the staple from rotating, when in an application shaft, to maintain a predetermined closing direction. The stapling element may be formed of an alloy, a pure metal, a polymer, or a composite of at least two materials. Additionally, staplers, anastomosis devices, and methods for their applications are described.

  • Patent number: 5951574
    Abstract: A multiple clip applier includes a handle portion and a pair of handles pivotably connected to opposite sides of the housing. A shaft extends from the housing and has a plurality of clips located within. A pair of opposed moveable jaws are attached to and extend from the distal end of the shaft. The jaws receive one of the clips serially when they are open and form the clip received serially when they close. A moveable forming mechanism is operatively connected to the handles by a pair of forming links. As the handles close, the forming mechanism closes the jaws to form the clip received therein, and as the handles are opened, the forming mechanism opens the jaws to receive another clip therein . A feeding mechanism is provided that has a moveable feed plate attached to the handles by a pair of feed links. The feed plate is releasably coupled to a clip pusher. As the handles are closed, the clip pusher remains stationary and uncoupled with the moving feed plate.

  • Patent number: 5830221
    Abstract: There is provided a surgical coil fastener applier for use in applying helical coil fasteners in surgical procedures, such as hernia repair, to affix surgical mesh to tissue. The coil fastener applier includes a housing having a handle extending therefrom and a trigger pivotally mounted on the housing. An elongated tubular portion extends from the housing and includes a drive rod rotatably supported therein and slidably supporting a plurality of coil fasteners thereon. A drive assembly is provided within the housing to rotate the drive rod and coil fasteners. The drive assembly includes an anti-reverse mechanism to allow rotation of the drive rod in only one direction. An actuation assembly is provided within the housing to convert the motion of the trigger into rotary motion for supply to the drive assembly. The drive assembly includes structure to limit the amount of rotary motion supplied to the drive assembly.

  • Patent number: 5814055
    Abstract: A surgical stapling instrument which has an elongated staple cartridge and anvil is disclosed. The anvil is movable relative to the cartridge from rearward to forward positions for insertion of tissue between these two components and clamping the tissue, respectively. A pair of spaced-apart ribs protrude from the anvil, and when the anvil is moved from its rearward to forward positions, these ribs are received into and slide within a groove embedded on the surface of the cartridge. In this manner, misalignment of the anvil and cartridge when tissue is being clamped is prevented or appreciably reduced, therefore reducing the chances of misforming the staples when the instrument is fired. The alignment features also act as tissue abutment surfaces to prevent the migration of tissue into a region where tissue is transected but not stapled.
