Patent number: 10631867Abstract: A surgical instrument includes an anvil selectively coupleable to a stapling head assembly and a trigger operable to fire staples into tissue compressed between the anvil and the stapling head assembly. In some versions, a lockout member may engage a securing feature to prevent actuation of the anvil relative to the stapling head assembly. For instance, a tab may engage a slot on an actuator, a screen door lock may provide frictional resistance or engage teeth on the actuator, a door may actuate into engagement with one or more recesses, geared teeth may mesh with teeth on the actuator, the lockout member may include a ratcheting assembly to engage actuator, and/or a push button may actuate into a recess while disengaging the lockout member. Alternatively, in some versions, the trigger actuation assembly may be disengaged prior to firing. An anvil position indicator may restrict engagement of the trigger actuation assembly.Type: GrantFiled: February 15, 2017Date of Patent: April 28, 2020Assignee: Ethicon LLCInventors: Christopher C. Miller, Edward G. Chekan, Johnny H. Alexander, III, John F. Cummings, Carl J. Shurtleff, Adam R. Dunki-Jacobs, Barry T. Jamison, Joseph E. Young, Cortney E. Henderson

Patent number: 10226246Abstract: A surgical instrument includes a handle assembly having a trigger operable to fire a staple driver to staple tissue. The instrument includes a pointed rod to which an anvil may be coupled. An anvil detection feature is included to determine when the anvil is coupled to the rod. In some versions, the anvil detection feature comprises a translatable rod that inhibits a lockout feature from disengaging. In other versions, an anvil sensing tube is disposed about the pointed rod and interferes with actuation of the trigger in a first position. A recess in the tube permits trigger to actuate when the anvil sensing tube is in the second position. Alternatively, a resilient tab is coupled to the pointed rod and resists actuation of the staple driver. A trigger lockout assembly may include a spring-loaded button that “pops” out when a push rod is actuated, thereby freeing a pivotable lockout feature.Type: GrantFiled: October 13, 2015Date of Patent: March 12, 2019Assignee: Ethicon LLCInventors: Kevin D.
