  • Patent number: 11051806
    Abstract: A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.

  • Patent number: 11039849
    Abstract: A clamping mechanism for a surgical instrument and related methods are disclosed. Upper and lower elongated members are configured to engage each other at a first interlock and a second interlock, the first interlock distal of the second interlock. The clamping mechanism is movable between a first configuration, a second configuration, and a third configuration. In the first configuration, the elongated members are approximated towards each other and the first and second interlocks are not engaged. In the second configuration, the distal portion of the elongated members are moved away from each other, the first interlock is engaged, and the second interlock is not engaged. In the third configuration, the distal portions of the elongated members are moved away from each other relatively, the proximal portions of the elongated members are moved away from each other relatively, the first interlock is engaged, and the second interlock is engaged.

  • Patent number: 11033266
    Abstract: A surgical stapler includes a first elongate member having a distal portion that supports a plurality of staple forming pockets, a second elongate member having a distal portion that receives a staple cartridge, and a clamp member operable to releasably clamp the first and second elongate members together. A retaining member is provided on one of the first elongate member or the second elongate member and is configured to releasably couple proximal ends of the first and second elongate members together with a resilient bias such that the first and second elongate members are pivotable relative to one another at the proximal ends. A decoupling mechanism is configured to overcome the resilient bias of the retaining member and thereby decouple the proximal ends from one another in response to the first and second elongate members being pivoted away from one another.

  • Patent number: 11033264
    Abstract: A fastener applying apparatus (20) includes an anvil half-section (100) and a cartridge receiving half-section (200) having a distal portion dimensioned to releasably receive a single use loading unit (“SULU”) (400) and a proximal portion configured to support a firing assembly (500). The firing assembly includes a stationary housing (502) and a firing lever (516) having one or more lever guide projections (522). The firing lever is slidable from a proximal end of the stationary housing to a distal end of the stationary housing to define a firing stroke. A clamping lever (300) is movable from an undamped position to a clamped position to releasably secure the distal anvil portion in close approximation with the SULU. The clamping lever defines one or more lever guide slots (316). The lever guide projection(s) is positioned to enter the lever guide slot(s) upon initiation of the firing stroke to inhibit movement of the clamping lever to the undamped position during the firing stroke.

  • Patent number: 10987104
    Abstract: A surgical device includes a jaw assembly, an articulating assembly and a drive shaft. The jaw assembly includes first and second jaws. The articulating assembly is removably coupled to a proximal end of the jaw assembly and includes a distal joint member, a proximal joint member, and a pivot pin. The pivot pin is fixedly coupled to the distal joint member and is rotatably coupled to the proximal joint member. The jaw assembly and the distal joint member together define a first longitudinal axis. The proximal joint member defines a second longitudinal axis. The drive shaft includes a gear element that is meshingly engaged with a pivoting gear element that is fixedly coupled to the pivot pin. Longitudinal movement of the first drive shaft pivots the jaw assembly relative to the proximal joint member about a pivot axis defined by the pivot pin.
