Patent number: 11963681Abstract: A surgical instrument comprises a body, shaft, and end effector. The shaft couples the end effector and body together. The end effector comprises an anvil and lower jaw configured to receive a surgical staple cartridge. The anvil is configured to pivot toward and away from the staple cartridge and lower jaw. The shaft assembly comprises a knife member configured to longitudinally translate to thereby substantially simultaneously cut clamped tissue and staple the severed tissue. The end effector may comprise lockout features configure to prevent longitudinal translation of the knife member. The end effector or staple cartridge may comprise lockout bypass features configured to prevent lockout of the knife member. These lockout bypass features may operate to permit longitudinal translation of the knife member once or multiple times. The end effector may comprise features configured to ensure proper alignment of the anvil relative to the staple cartridge.Type: GrantFiled: December 22, 2020Date of Patent: April 23, 2024Assignee: Cilag GmbH InternationalInventors: Jason M. Rector, Douglas B. Hoffman, Robert J. Simms, John C. Schuckmann, Ryan J. Laurent, Frederick E. Shelton, IV, Jeffrey C. Gagel, Nicholas Fanelli

Patent number: 11957340Abstract: A surgical stapler includes a first stapler half including an anvil surface having a plurality of staple forming pockets, and a second stapler half configured to releasably couple with the first stapler half. The second stapler half is operable to deploy staples toward the anvil surface. The stapler also includes a projection positioned on one of the stapler halves and extending laterally relative to a longitudinal axis of the stapler. The stapler halves are configured to pivot relative to each other about the projection. The stapler further includes a locking member positioned on the other of the stapler halves. The locking member is configured to translate along the longitudinal axis of the stapler between a locked state in which the locking member selectively captures the projection and an unlocked state in which the locking member selectively releases the projection. The locking member is biased proximally toward the locked state.Type: GrantFiled: January 5, 2022Date of Patent: April 16, 2024Assignee: Cilag GmbH InternationalInventors: Brian D. Schings, Jason D.

Publication number: 20220218348Abstract: A surgical instrument with a tissue-clamping end effector, where actuation of the instrument is locked out when the thickness of the tissue clamped in the end effector is not within a specified thickness range. The end effector may comprise a tissue thickness module that senses the thickness of the tissue clamped in the end effector. The surgical instrument also comprises a control circuit in communication with the tissue thickness module. The control circuit prevents actuation of a working portion of the end effector when the thickness of the tissue clamped in the end effector is not within the specified thickness range.Type: ApplicationFiled: January 26, 2022Publication date: July 14, 2022Inventors: Brett E.
