  • Patent number: 11399827
    Abstract: An apparatus includes a first portion having a handle and a jaw, a second portion having a handle and a jaw, a latching member, and a proximal coupling assembly. The second portion may selectively pivot about a proximal location relative to the first portion. The latching member drives the first jaw and the second jaw toward a fully closed configuration. The first jaw and second jaw may clamp, cut, and staple tissue between the jaws. The proximal coupling selectively attaches the first portion with the second portion. The proximal coupling includes a pivot body and a coupling body. The pivot body is pivotally attached to the first portion at the proximal location. The coupling body, which is associated with the second portion, engages the pivot body at a location distal to the proximal location to selectively attach the first portion with the second portion.

  • Patent number: 11382627
    Abstract: A surgical stapling assembly comprising an anvil, a cartridge channel, a staple cartridge configured to be operably positioned in the channel, a firing member, and a ramp is disclosed. The channel comprises a base, an elongate internal slot, and a proximal channel opening defined in the base. The elongate internal slot comprises an encased internal passageway. The proximal channel opening is separate from the elongate internal slot. The firing member is movable from a first position to a second position distal to the first position. The firing member comprises a lateral extension configured to be received in the encased internal passageway as the firing member travels through the elongate internal slot during a firing motion. The proximal channel opening is configured to indicate when the firing member is in the first position. The ramp is for guiding the lateral extension into the encased internal passageway during the firing motion.

  • Patent number: 11369369
    Abstract: This application provides a linear stapler with an adjusting mechanism having wider adjusting scope and more suitable pressing force and being more convenient to operate, and including an adjusting shift lever with at least one step surface on each of upper and lower ends, an adjusting slider with multiple step surfaces on an end surface close to the adjusting shift lever, and an adjusting chassis having multiple step surfaces on an end surface close to the adjusting shift lever. The adjusting shift lever rotates with a shifted adjusting knob to generate relative displacement vertical to the step surface with the adjusting slider at one end and relative displacement vertical to the step surface with the adjusting chassis at the other end, and drive a nail abutting seat subassembly to rotate relatively to a nail bin seat, until the thickness of clamped tissue is consistent in near and far ends.

  • Patent number: 11272937
    Abstract: An end effector for use with a surgical stapler includes a staple cartridge assembly movable relative to an anvil assembly. The staple cartridge assembly defines a plurality of retention slots and a cavity. The staple cartridge assembly includes a plurality of staples, a plurality of pushers, an actuation sled, a surgical buttress material, a suture, and an anchoring button. The actuation sled is configured for movement along a length of the staple cartridge assembly to sequentially engage the plurality of pushers to eject the plurality of staples through the respective plurality of retention slots. The anchoring button is configured to be received in the cavity of the staple cartridge assembly such that a portion of the suture is supported in the cavity to be severed by a knife blade of the actuation sled when the actuation sled is advanced distally.
