  • Patent number: 10213520
    Abstract: Surgical adjuncts having medicants controllably releasable therefrom are provided. In general, an adjunct retaining at least one medicant controllably releasable therefrom can be configured to be responsive to one or more physiological triggers. The adjunct can be provided with the at least one medicant releasably retained within the adjunct. In general, the one or more physiological triggers can each include an environmental condition to which the adjunct is exposed, such as when the adjunct is positioned within a body, such as by being stapled to tissue. Various physiological triggers can affect the adjunct, causing the adjunct to release the at least one medicant to the surrounding tissue in a selectable elution profile depending on the physiological trigger(s) that affect a particular adjunct.

  • Patent number: 10143513
    Abstract: A surgical instrument is separable into a transducer unit and a lower body portion. The lower body portion includes a waveguide and a casing. The transducer unit includes a transducer and a geared mechanism operable to couple the transducer to the waveguide. In some versions the geared mechanism includes bevel gears coupled to a rack and pinion such that linear motion may be used to rotatably couple a transducer to a waveguide. The rack gear may further include a handle extending out of the transducer unit casing to be actuatable by a user. The rack gear may also be flexible or rigid. In other versions, the bevel gears may be coupled to a threaded shaft that is operable to translate the transducer into the waveguide to form an interference fit. The transducer unit may also include a slide lock mechanism to couple to the casing of the lower body portion.

  • Patent number: 9999408
    Abstract: An apparatus comprises a surgical instrument and a buttress configured to hold a fluid adhesive. In some versions, the buttress contains a two-part fluid adhesive where two fluid materials form a fluid adhesive when combined. In some versions, the buttress is configured to be compressed by the surgical instrument thereby pressurizing a portion of the buttress. Thereafter, the buttress may be severed and the pressurized region may be operable to urge the fluid adhesive to a tissue site.

  • Patent number: 9987000
    Abstract: A surgical instrument can include a shaft, an end effector, and an articulation joint configured to permit the end effector to rotate relative to the shaft about the articulation joint. The surgical instrument can further comprise a first articulation actuator for rotating the end effector in a first direction and a second articulation actuator for rotating the end effector in a second direction. The articulation actuators can be configured to push the end effector. The articulation actuators can assume different configurations depending on whether they are experiencing a compressive load or a tensile load. The articulation joint can comprise an articulation frame which forms a proximal joint with the shaft and a distal joint with the end effector. The joints can comprise fixed axis joints and/or ball-and-socket joints, for example. The articulation joint can comprise links having different sizes to facilitate the articulation of the articulation joint.

  • Patent number: 9980742
    Abstract: An ultrasonic surgical instrument includes a shaft, a first jaw having a proximal end at the distal end of the shaft, a second jaw and an ultrasonic waveguide. The first jaw has an internal trough running through the proximal end of the first jaw and a surface on either side of the trough. The second jaw has a surface facing the surface of the first jaw. The waveguide extends beyond the shaft and slidably engages the trough and has a blade with a tissue compressing surface upwardly sloping proximally from a distal end thereof the blade and having an upper portion and a substantially horizontal top surface portion at the upper portion. The tissue compressing surface and/or the top surface portion forms a cutting surface. When the jaws compress tissue therebetween, the blade slides within the trough to further compress and cut the compressed tissue as the blade moves distally.
