  • Patent number: 10799240
    Abstract: A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. An E-beam firing bar moves distally through the clamped end effector to sever tissue and to drive staples on each side of the cut. The E-beam firing bar affirmatively spaces the anvil from the elongate channel to assure properly formed closed staples, especially when an amount of tissue is clamped that is inadequate to space the end effector. In particular, an upper pin of the firing bar longitudinally moves through an anvil slot and a channel slot is captured between a lower cap and a middle pin of the firing bar to assure a minimum spacing. Forming the E-beam from a thickened distal portion and a thinned proximal strip enhances manufacturability and facilitates use in such articulating surgical instruments.

  • Patent number: 10653414
    Abstract: An anvil assembly is provided. The anvil assembly includes an anvil center rod, a head assembly pivotally secured to the anvil center rod assembly from an operative position to a tilted position, and a sleeve slidably disposed about the anvil center rod. The sleeve is associated with the head assembly such that movement of the head assembly from the operative position towards the tilted position effects proximal movement of the sleeve about the anvil center rod.

  • Patent number: 10646223
    Abstract: A universal surgical handle (10) includes a body (12) having a moveable handle (18), and elongate member (13) extending distally from the body (12), an actuation shaft (20), and a fire lock mechanism (60). The actuation shaft (20) defines first and second lock slots (24, 25) spaced axially apart. The moveable handle (18) is operatively associated with the actuation shaft (20) to effect longitudinal movement of the actuation shaft (20). The fire lock mechanism (60) has a lock pawl (62) that is received within the first lock slot (24) during a first mode of operation of the handle (10) to lock the actuation shaft (20) in first longitudinal position and is received within the second lock slot (25) during a second mode of operation of the handle (10) to lock the actuation shaft (20) in a second longitudinal position. The handle (10) is adapted to transition from a home position to the first or second mode of operation in response to a loading unit (110, 210) being coupled to the elongate member (13).

  • Patent number: 10639111
    Abstract: An instrument adapter includes a housing, a drive member, a nut, and a shaft assembly. The nut is threadedly coupled to the drive member and axially movable relative thereto. The shaft assembly includes a shaft and a link. The shaft extends distally from the housing and is configured to be operably coupled to an end effector. The link has a proximal end movably coupled to the nut and a distal end configured to selectively lock the end effector to the shaft assembly. The link is movable between a proximal non-locking position, and a distal locking position. The nut is movable between a first position along the drive member, in which the nut resists proximal movement of the link from the distal position to the proximal position, and a second position, in which the nut does not resist proximal movement of the link from the distal position to the proximal position.

Such co-operating features can also releasably retain the layer to the cartridge body. In addition to or in lieu of the above, the anvil and the layer comprise co-operating features which reduce relative movement between the anvil and the layer. Such co-operating features can also releasably retain the layer to the anvil. In certain instances, the layer can be positioned against the anvil, but releasably attached to the cartridge. The layer can comprise buttress material and/or a tissue thickness compensator, for example.
