  • Publication number: 20220079593
    Abstract: A method is provided for applying an adjunct element to a surgical stapler end effector having first and second stapling surfaces using an applicator. The method includes providing the end effector in an open state in which the first and second stapling surfaces are spaced apart. With the end effector in the open state, at least a portion of the applicator is positioned between the first and second stapling surfaces. Without engaging a closure system input feature of the surgical stapler, a portion of the end effector is compressively engaged by the applicator to thereby secure the adjunct element to one of the first or second stapling surfaces. The applicator and the end effector are withdrawn relatively away from one another so that the adjunct element remains attached to the one of the first or second stapling surfaces of the end effector.

  • Patent number: 11272930
    Abstract: A method of surgical stapling uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The placement tip is elastically deformable when the placement tip is subject to a clamping force. In some instances the placement tip includes an arcuate bend, while in other instances the placement tip is straight. The placement tip can have a variety of non-rectangular lateral cross-sectional shapes. In some instances, the placement tip is made of a material of a specified durometer range and having a high color contrast. A distal end of the placement tip may change position based on the state of deflection of the placement tip in response to the clamping force.

  • Patent number: 11219453
    Abstract: A surgical stapling instrument is disclosed that includes a first jaw configured to removably support a surgical staple cartridge therein and a second jaw that is movable relative to the first jaw between an open position and a closed position. A closure lockout is movable between a locked position wherein the second jaw is retained in the open position by the closure lockout and an unlocked position wherein the second jaw is movable to the closed position. The closure lockout is configured to interface with an unlocking feature on a surgical staple cartridge supported in the first jaw such that when the unlocking feature operably interfaces with the closure lockout, the closure lockout moves to the unlocked position. The stapling instrument may further include a firing member lockout system for preventing movement of a firing member unless a camming assembly of the staple cartridge is in an unfired position.
