Patent number: 11337696Abstract: A surgical stapling device for sequentially applying a plurality of fasteners to body tissue and simultaneously incising tissue is provided. The surgical stapling device is adapted to receive disposable loading units having staples in linear rows whose length can be between about 30 mm and 60 mm. The disposable loading unit includes a proximal body portion, a mounting assembly and a tool assembly. The mounting assembly is secured to the proximal end of the tool assembly and pivotally mounted about a pivot axis to the distal end of the proximal body portion. A support member or blow-out plate assembly is positioned on opposite sides of the pivot axis and extends between the proximal body portion and the mounting assembly.Type: GrantFiled: February 25, 2020Date of Patent: May 24, 2022Assignee: Covidien LPInventors: Thomas Wenchell, Stanislaw Marczyk, Kenneth H. Whitfield, Roman Czernik, Henry E. Holsten, Frank C. Maffei

Patent number: 11123066Abstract: A surgical fastener applying apparatus includes an elongate body portion having proximal and distal ends, an end effector including a first movably coupled to a second jaw that is positioned at the distal end of the elongate body portion, and an introducer member. The introducer member has proximal and distal portions, and is configured and dimensioned for releasable connection with the end effector. The introducer member is at least partially formed from a flexible material, and is configured and dimensioned to separate target tissue from collateral tissue prior to positioning of the target tissue between the first and second jaws of the end effector.Type: GrantFiled: September 10, 2018Date of Patent: September 21, 2021Assignee: Covidien LPInventors: John W. Beardsley, Stanislaw Kostrzewski, Frank C. Maffei, Lee Ann Olson, Sachin Shah, William R. Mayfield

Patent number: 10617415Abstract: A surgical stapling device includes a body portion, a tool assembly, a mounting assembly, a retaining member, and an articulation member that is coupled to the tool assembly for articulating the tool assembly in relation to the body portion. The retaining member is engaged with the articulation member to prevent movement of the articulation member until the articulation member is actuated.Type: GrantFiled: March 7, 2017Date of Patent: April 14, 2020Assignee: Covidien LPInventors: Thomas Wenchell, Stanislaw Marczyk, Kenneth H. Whitfield, Roman Czernik, Henry E. Holsten, Frank C. Maffei

Patent number: 10568623Abstract: A surgical instrument comprising a handle assembly, and actuation member, an elongated body portion, and a locking mechanism is disclosed. The locking mechanism is disposed in mechanical cooperation with the actuation member, and is configured to substantially prevent at least a partial movement of the actuation member when the elongated body portion is not engaged with a loading unit. The locking mechanism comprises a link, a bushing, and a connecting member. The link is configured for mechanical engagement with a portion of a loading unit. At least a portion of the busing is disposed proximally of at least a portion of the link. At least a portion of the connecting member is disposed proximally of at least a portion of the bushing. Engagement between a loading unit and the elongated body portion causes proximal movement of the link, the bushing, and the connecting member.Type: GrantFiled: October 18, 2016Date of Patent: February 25, 2020Assignee: COVIDIEN LPInventors: Kenneth M. Cappola, Lee Ann Olson, Frank C. Maffei
