  • Publication number: 20230248362
    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 The applicator and the end effector are withdrawn relatively away from one another so that the adjunct element remains attached to the one of the first or second stapling surfaces of the end effector.

  • Publication number: 20230210528
    Abstract: A method of applying a buttress to a surgically cut and stapled site uses an end effector with a buttress applier cartridge assembly to load one or more buttress assemblies to the end effector. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The adhesive of the buttress assemblies can include a pattern to assist in both attachment to the end effector and release from the end effector after cutting and stapling a tissue site. The buttress applier cartridge can include features that accommodate end effectors having various tip configurations, including straight tips and curved or bent tips.

  • Patent number: 11684412
    Abstract: A surgical instrument with a rotatable and articulatable end effector. The end effector includes first and second jaws that are movable between an open position and a closed position by an axially movable drive member. The end effector is coupled to an elongate shaft such that the end effector is rotatable relative to the shaft about a shaft axis when the drive member is rotated. A releasable lock system is provided to selectively lock the end effector in a desired rotary position.

  • Patent number: 11666375
    Abstract: Aspects of the present disclosure include a surgical device comprising electrodes on the sides of an end of an effector to aide in sealing during various surgical procedures, such as a liver resection. During a sealing procedure, the surgeon may wipe the surgical site with the end effector, causing the electrodes to touch the fractured area. Electrosurgical energy may be applied to the electrodes during the wiping, causing coagulation of smaller vessels, such as tiny blood vessels and bile ducts in the parenchyma of the liver. In some cases, due to the nature of some smaller vessels, electrosurgical energy should be delicately applied to cause sealing but to avoid overly damaging the remaining tissue. In some embodiments, the thin design of the electrodes allows for an appropriate amount of electrosurgical energy to be applied to the fractured area.

  • Publication number: 20230165582
    Abstract: A method for creating a flexible fastener line is disclosed. The fastener line comprises fasteners oriented in directions which are transverse or oblique to a tissue incision created by a cutting member. The fasteners can translate and/or rotate within the tissue when the tissue is stretched thereby creating flexibility within the tissue.

  • Publication number: 20230113152
    Abstract: A method of applying a buttress to a surgical stapler end effector comprises positioning a buttress assembly between an anvil and a staple cartridge of the end effector. The buttress assembly comprises a buttress body and an adhesive material. The adhesive material faces either an underside of the anvil or a deck of the staple cartridge. The anvil is in an open position relative to the staple cartridge during the act of positioning the buttress assembly between the anvil and the staple cartridge. The method further comprises moving the anvil toward the staple cartridge then moving the anvil back to the open position. The buttress assembly is adhered to the underside of the anvil or the deck of the staple cartridge via the adhesive material with the anvil moved back to the open position. The adhesive material comprises a bioabsorbable polymer.

  • Publication number: 20230072574
    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: 11564683
    Abstract: An apparatus is configured to apply an adjunct material to at least one of a first stapling surface or a second stapling surface of a surgical stapler. The apparatus includes a contact structure defining a longitudinal axis and an expansion mechanism. The contact structure includes a first contact member configured to support a first portion of the adjunct material and a second contact member movably coupled with the first contact member that is configured to support a second portion of the adjunct material. The first and second contact members are configured to move away from one another in opposing directions to apply the first portion of the adjunct material to the first stapling surface and the second portion of the adjunct material to the second stapling surface. The expansion mechanism is selectively operable to transition the contact structure from a non-expanded state toward the expanded state.
