Patent number: 11141159Abstract: A surgical instrument includes an end effector extending along a jaw centerline. A staple cartridge is received in the end effector. The staple cartridge includes deck, staples, a wedge sled, and a driver assembly. The staples are positioned in respective openings formed through the deck. The wedge sled is slidable through the staple cartridge. The driver assembly has a first driver and a second driver. The first driver receives a first staple of the plurality of staples. The second driver receives a second staple of the plurality of staples. The driver assembly is configured to be engaged by the wedge sled sliding toward the distal sled position and thereby be forced toward a first jaw of the end effector, thereby forcing the first and second staples toward an anvil of the first jaw for formation in tissue. The driver assembly is positioned along the centerline.Type: GrantFiled: October 15, 2015Date of Patent: October 12, 2021Assignee: Cilag GmbH InternationalInventors: Charles J. Scheib, Frederick E.

Publication number: 20200337700Abstract: A surgical stapler includes a body, a shaft assembly, and an end effector configured to receive a staple cartridge. The end effector is actuatable between an open state for receiving tissue and a closed state for clamping the tissue. A closure system operatively coupled with the end effector is operable to actuate the end effector from the open state to the closed state. A firing system operatively coupled with the end effector is actuatable to fire the end effector to staple and cut the clamped tissue. A lockout member operatively coupled with the closure system and the firing system is configured to inhibit actuation of the closure system to prevent closure of the end effector when an unspent staple cartridge is absent from the end effector. The lockout member is also configured to inhibit actuation of the firing system to prevent repeated firing with the same staple cartridge.Type: ApplicationFiled: April 26, 2019Publication date: October 29, 2020Inventors: Jesse L. Hontz, Jason M. Rector, Nicholas Fanelli

Publication number: 20200337699Abstract: A surgical stapler includes a body, a shaft assembly, and an end effector at a distal end of the shaft assembly. The end effector is actuatable between an open state for receiving tissue and a closed state for clamping the tissue. A closure system is operable to actuate the end effector from the open state to the closed state. A firing system is operable to actuate the end effector in the closed state to staple the clamped tissue. A firing lockout mechanism is movable between a lockout state that inhibits actuation of the firing system, and a bypass state that permits actuation of the firing system. The firing lockout mechanism is configured to maintain the lockout state until the end effector assumes the closed state, and is further configured to transition from the lockout state to the bypass state in response to the end effector assuming the closed state.Type: ApplicationFiled: April 26, 2019Publication date: October 29, 2020Inventors: Jason M.
