Patent number: 11801049Abstract: A surgical stapler includes first and second elongate members, a clamp member, and a firing assembly. The second elongate member is configured to receive a staple cartridge. The clamp member is operable to releasably clamp the first elongate member against the second elongate member. The firing assembly is translatable to fire the staple cartridge. The firing assembly includes a slider and an actuator configured to be selectively actuated by a user. The slider includes inner and outer engagement features. The actuator includes inner and outer engagement features. The inner engagement feature of the actuator is configured to engage with the inner engagement feature of the slider at a first interface when the actuator moves relative to the slider. The outer engagement feature of the actuator is configured to engage the outer engagement feature of the slider at a second interface when the actuator moves relative to the slider.Type: GrantFiled: September 2, 2021Date of Patent: October 31, 2023Assignee: Cilag GmbH InternationalInventors: Nicholas D. Courtwright, Barry Thomas Jamison, Michael S. Cropper, Bradley A. Arnold

Publication number: 20230309998Abstract: A cartridge for use with a surgical instrument includes a curved body and a deck defined by the curved body and configured to clamp tissue against an anvil. A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot is formed in the deck and is configured to slidably receive a cutting member therethrough. The deck includes a sloped deck portion that slopes away from the arcuate slot in a direction transverse to a length of the arcuate slot. The sloped deck portion is configured to provide varied compression of tissue across a width of the deck.Type: ApplicationFiled: May 24, 2023Publication date: October 5, 2023Inventors: Ryan P. Posey, Nicholas D. Courtwright, Stephen D. Geresy, Kevin D. Sackett, Frederick E. Shelton, IV

Publication number: 20230007859Abstract: A surgical instrument includes a body, a shaft, and an end effector. The end effector includes a staple cartridge unit having a housing and an anvil configured to form staples ejected from the housing into tissue. The end effector also includes a cartridge retaining member having an opposed pair of jaws configured to cooperate to grip the housing of the staple cartridge unit. The end effector further includes a deflectable retention member configured to removably secure the housing of the staple cartridge unit to the cartridge retaining member. The deflectable retention member is presented by one of the staple cartridge unit or the cartridge retaining member, and is configured to be deflected relative to a portion of the one of the staple cartridge unit or the cartridge retaining member from an undeflected state to a deflected state by the other of the staple cartridge unit or the cartridge retaining member.Type: ApplicationFiled: May 31, 2022Publication date: January 12, 2023Inventors: Thomas E. Adams, Nicholas D. Courtwright, Daniel A. Palmer

Publication number: 20220330941Abstract: 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.Type: ApplicationFiled: May 25, 2022Publication date: October 20, 2022Inventors: Nicholas D. Courtwright, Jason E. Zerkle

Patent number: 11464508Abstract: A surgical stapler includes a first elongate member, a second elongate member, a clamp member, and a firing assembly. The first elongate member includes a distal portion that supports an anvil surface that includes a plurality of staple forming pockets. The second elongate member includes a distal portion that is configured to receive a staple cartridge. The clamp member is operable to releasably clamp the first elongate member against the second elongate member. The firing assembly is translatable from a first longitudinal position to a second longitudinal position to fire the staple cartridge. The firing assembly includes a slider and an actuator. The slider includes a first coupling feature. The actuator is configured to be selectively actuated by a user. The actuator includes a second coupling feature that is configured to generally surround the first coupling feature of the slider when the actuator moves relative to the slider.Type: GrantFiled: May 13, 2019Date of Patent: October 11, 2022Assignee: Cilag GmbH InternationalInventors: Nicholas D. Courtwright, Barry Thomas Jamison, Michael S. Cropper, Bradley A. Arnold

A plurality of staple openings is formed in the deck and is configured to house a plurality of staples. An arcuate slot formed in the deck is configured to slidably receive a cutting member therethrough. An opening formed in the deck adjacent to an end of the arcuate slot is configured to slidably receive a pin therethrough. The cartridge further includes a raised surface offset from the deck and extending circumferentially about at least a portion of the opening. The raised surface is configured to clamp tissue against the anvil to thereby fix the tissue relative to the opening.Type: ApplicationFiled: August 27, 2021Publication date: February 17, 2022Inventors: Ryan P. Posey, Nicholas D. Courtwright, Stephen D. Geresy, Kevin D. Sackett, Frederick E. Shelton, IV
