Publication number: 20210204969Abstract: A forceps includes first and second shafts, each having a jaw member disposed at a distal end thereof. At least one jaw member is moveable from an open to a closed position for grasping tissue therebetween. At least one jaw member is configured for reciprocation of a blade therethrough. A trigger assembly includes a trigger and at least one linkage coupled to the trigger and to the blade such that rotation of the trigger translates the blade between the retracted and the extended position. An interference member moveable between a locked position and an unlocked position is also provided. The interference member is configured to engage the linkage(s) when in the locked position to inhibit translation of the blade from the retracted to the extended position.Type: ApplicationFiled: March 18, 2021Publication date: July 8, 2021Inventors: Ryan C. Artale, Thomas W. Meiser, William J. Dickhans, Steven E. Butcher, Dennis W. Butcher

Patent number: 9326812Abstract: A surgical instrument is provided and includes a housing including an elongated shaft. The housing includes a docking portion that includes one or more apertures defined therein and electrical circuitry disposed therein. An end effector is operably supported at a distal end of the elongated shaft. A battery assembly is selectively and pivotably engageable with the docking portion of the housing and configured to generate electrical energy. The battery assembly includes one or more protrusions that are configured to releasably engage the aperture(s) on the docking portion and a latch mechanism that is movable from an initial position for latching the battery assembly to the docking portion to a subsequent position for unlatching the battery assembly from the docking portion. The battery assembly is adapted to communicate with the electrical circuitry of the docking member upon insertion of the battery assembly into the at least one aperture.Type: GrantFiled: January 25, 2012Date of Patent: May 3, 2016Assignee: Covidien LPInventors: Luke Waaler, Duane E. Kerr, Diana Gunnarson, Robert B. Stoddard, Sean T. O'Neill, Steven E. Butcher, William E. Robinson, Cody C. Taylor
