  • Publication number: 20200237434
    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: 20200205823
    Abstract: A buttress applier cartridge assembly includes a buttress assembly and a buttress applier cartridge. The buttress assembly includes a buttress configured to support a staple formed therein as well an adhesive layer for adhering to an end effector. The buttress applier cartridge includes a housing defining a gap extending in a longitudinal direction as well as a platform. The platform extends longitudinally from a proximal portion to a distal portion and is exposed in a transverse direction adjacent to the gap. The proximal and distal portions respectively have a proximal stiffness and a different, distal stiffness in the transverse direction. Thereby, the proximal and distal portions support the buttress assembly thereon to deform with the proximal and distal stiffnesses and provide reactionary forces of at least the predetermined minimum force while receiving the end effector for accommodating various camber orientations of the end effector.

  • Patent number: 10610226
    Abstract: Adjunct material and methods of using adjunct material to reinforce a staple line are provided herein. In general, adjunct material can be used to maintain a seal in tissue and prevent stapled tissue from tearing. This adjunct material can be coupled to a jaw of a surgical stapler, and can be deployed into tissue along with the staples. In some embodiments, the adjunct material can be sized and shaped so that a portion of the material extends laterally outside of the staple line and distributes strain to tissue outside of the staple line. In certain aspects, sealant can be applied to the staple line and to the adjunct material in various ways to further seal the tissue and/or prevent leaks from forming in the tissue.

  • Patent number: 10548655
    Abstract: Aspects of the present disclosure include an attachable power and control system to supply energy to electrodes of a wiping electrode coagulation system of a surgical device. A surgical device includes electrodes at an end of effector to aide in sealing during various surgical procedures. During the 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. The attachable power and control system may be configured to slide over the shaft of the surgical device. The power and control system also may be configured to supply power to the electrodes and to control when energy is applied to the electrodes, based in part, for example, on measuring a distance or angle of the opening of the jaws at the end effector.
