  • Publication number: 20210346022
    Abstract: A method of applying a buttress to a surgically cut and stapled site uses an end effector with a buttress applier cartridge assembly to load one or more buttress assemblies to the end effector. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The adhesive of the buttress assemblies can include a pattern to assist in both attachment to the end effector and release from the end effector after cutting and stapling a tissue site. The buttress applier cartridge can include features that accommodate end effectors having various tip configurations, including straight tips and curved or bent tips.

  • Patent number: 11166725
    Abstract: A surgical system and related methods includes a buttress applier cartridge, a first buttress assembly, and a second buttress assembly. The buttress applier cartridge has a housing and a platform. The first and second buttress assemblies respectively includes first and second buttresses and first and second adhesive layers thereon. The first adhesive layer is parallel to the first buttress and defines a first adhesive pattern having a first outer adhesive profile. The second adhesive layer is parallel to the second buttress and defines a second adhesive pattern having a second outer adhesive profile. The exposed second outer adhesive profile in the transverse direction is the same as the exposed first outer adhesive profile in an opposite transverse direction such that the first and second buttress assemblies are interchangeable with the first and second portions of the end effector of the surgical instrument.

  • Patent number: 7398881
    Abstract: A retainer ring for use in a welding wire package wherein the package houses a coil of welding wire positioned in a coil receiving cavity in the package. The coil extends about a vertically extending coil axis and includes a coil bottom, an oppositely facing coil top, a radially extending outer cylindrical surface and a radially inner cylindrical surface. The ring haves an annular ring body extending about a ring axis with an outer peripheral edge and an inner peripheral edge. The ring body further includes a top surface extending between the outer and inner peripheral edges and an oppositely facing bottom surface extending between the outer and inner peripheral edges. The bottom surface of the body can be configured to rest on the coil top and the outer peripheral edge is sized to allow the ring to descend within the wire receiving cavity as the wire is unwound from the wire coil.

  • Patent number: 7100863
    Abstract: A floating liner for a container of welding wire which floating liner includes a tube having two ends and a passageway extending between the two ends. The floating liner is unsupported between the top of the container and the retaining ring. The floating liner is designed to provide structural support to the wire and added stiffness or rigidity to the wire to inhibit buckling of the wire, knot formation in the wire that can form between the retaining ring and the top of the container. The floating liner has a weight profile that causes one end of the tube to at least partially float above the top surface of a layer of welding wire or retaining ring in the container as the welding wire is paid out of the container.

  • Patent number: 7004318
    Abstract: A payout for controlling the unwinding of a coil of wire from a wire drum which has an outer drum body and an inner core substantially coaxial with the drum body includes a first planar ring juxtaposed the top of the wire coil and having a first inner edge closely adjacent to the core and a first outer edge spaced from the first inner edge and a second planar ring juxtaposed the top of the wire coil and having a second outer surface closely adjacent the drum body and a second inner surface spaced from the first outer surface of the first ring to define a continuous circular gap above the wire coil such that the wire passes upwardly through the gap as it is withdrawn from the wire coil. A third ring overlies the first and second rings and is laterally displacable relative thereto and eccentrically relative to the drum axis to further control payout of the wire. The second and third rings along can be used to control payout of the wire.
