  • Publication number: 20230371954
    Abstract: A surgical instrument includes a body, a shaft assembly, a stapling head assembly, an anvil, an anvil adjustment assembly, a trigger, and a lockout assembly. The stapling head assembly is operable to drive an annular array of staples. The anvil is configured to couple with the stapling head assembly. The anvil adjustment assembly includes a translating member, which translates relative to the body to thereby adjust the longitudinal position of the anvil relative to the stapling head assembly. The trigger is operable to actuate the stapling head assembly. The lockout assembly includes an electrically powered braking feature. A method of operating the surgical instrument includes providing the lockout assembly in a first state to permit translation of the translating member. The translating member is then translated. The lockout assembly is then transitioned to a second state to prevent further translation of the translating member.

  • Patent number: 11684363
    Abstract: An apparatus includes a body, a shaft in communication with the body, and an end effector in communication with the shaft. The end effector is operable to drive staples through tissue. The end effector comprises an anvil and a cartridge. The anvil is operable to move pivotally relative to the cartridge. The cartridge is positioned to drive staples upwardly toward the anvil. The cartridge comprises a plurality of protrusions operable to prevent lateral rocking of the anvil. The plurality of protrusions is pointed toward the anvil. In some versions, an alignment member and/or a lateral stabilization member may be used between the anvil and the cartridge.

  • Publication number: 20220409267
    Abstract: An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft. The end effector includes a pair of jaws that are operable to deliver RF energy to tissue that is clamped between the jaws. The cutting member is operable to sever tissue that is clamped between the jaws. The shaft extends between the body and the end effector. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. Some versions include a rotation section that is distal to the articulation section. The rotation section is operable to rotate the end effector relative to the articulation section.

  • Publication number: 20220330941
    Abstract: An apparatus includes a housing, an anvil, a backing member, and a concave surface. The housing has a plurality of staples and the anvil is opposed from the housing such that the anvil and the housing are configured to cooperate to clamp tissue. The anvil is configured to form staples ejected from the housing into the clamped tissue. The backing member is coupled with the anvil and the concave surface defines a gap between the backing member and an adjacent component of the apparatus. The anvil is configured to deflect in a direction towards the gap in response to actuation of the apparatus to at least one of clamp tissue or staple tissue.
