Publication number: 20190150919Abstract: A surgical stapling apparatus (stapler) is provided. The stapler includes a housing, elongated member, and a reload. A cartridge is configured to selectively couple to a first jaw member of the reload and includes one or more resilient members thereon. An anvil operably supported on a second jaw member of the reload is configured to compress one or more fasteners ejected from the cartridge. The anvil includes one or more locking members thereon. A knife is configured to translate through the cartridge and anvil when the first and second jaw members are in a closed configuration. Engagement between the knife and the resilient member(s) causes the resilient member(s) to move from an initial configuration that allows the knife to travel distally past the locking member(s) to a final configuration that allows the locking member(s) to engage the knife.Type: ApplicationFiled: January 18, 2019Publication date: May 23, 2019Inventors: Justin Williams, Christopher Penna, Lee Ann Olson, Stanislaw Marczyk, Kenneth M. Cappola, Thomas R. Hessler, Ernest Aranyi, Stanislaw Kostrzewski

Publication number: 20190083088Abstract: A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes.Type: ApplicationFiled: November 20, 2018Publication date: March 21, 2019Inventors: David Racenet, Ralph Stearns, John Beardsley, Philip Roy, Lee Ann Olson

Patent number: 10219805Abstract: A tool assembly for a surgical stapling device includes a channel member for supporting a staple cartridge therein and an anvil to deform a plurality of staples ejected from the staple cartridge thereagainst. The tool assembly also includes a sled which is movable to force the staples from the cartridge against the anvil to staple tissue disposed between the anvil and the staple cartridge. A dynamic clamping member is included which has a pin which movably engages the anvil and a flange which movably engages the channel assembly. The dynamic clamping member is mounted to and movable with the sled. The pin and the flange of the dynamic clamping member cooperating to oppose the forces associated with clamping and stapling tissue and also to maintain a substantially uniform gap between the anvil and the staple cartridge during stapling of the tissue.Type: GrantFiled: November 20, 2018Date of Patent: March 5, 2019Assignee: Covidien LPInventors: Lee Ann Olson, Philip Roy, John W.
