Patent number: 11291443Abstract: A surgical apparatus has a clamp and a stapling mechanism. The clamp has a first jaw and a second jaw to clamp on a body tissue at a desired location for a stapling operation. The stapling mechanism is controlled by a trigger handle or a switch assembly. The surgical apparatus has a controller for providing a delay between clamping and actuating of the firing mechanism of the stapling mechanism. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation. The surgical apparatus also has an indicator. The indicator provides feedback about the status of the stapling mechanism and also displays a time of tissue compression by the clamp.Type: GrantFiled: May 14, 2019Date of Patent: April 5, 2022Assignee: Covidien LPInventors: Frank J. Viola, Gregg Krehel, Guido Pedros, Michael A. Soltz, Robert DeSantis, Henry E. Holsten, Russell Heinrich, Michael Ingmanson, Philip Irka, David M. McCuen, Gene A. Stellon

Patent number: 10526824Abstract: An interconnected lock has adjustable offset spacing between latchbolt and deadbolt lock mechanisms, and a sliding pusher mechanism therebetween. The pusher mechanism is operable upon operation of an interior actuator to bear against the deadbolt lock mechanism and move the deadbolt along the second axis from the latched to the unlatched position at the same time that the operation of the interior actuator moves the latchbolt along the first axis from the latched to the unlatched position. The pusher mechanism includes an arm that bears against the deadbolt lock mechanism and may be retracted and extended between a first length and a second, longer length when changing offset spacing between the deadbolt and latchbolt. The arm is extendable from the first length to the second length without adding or removing any components thereof.Type: GrantFiled: October 10, 2014Date of Patent: January 7, 2020Assignee: SARGENT MANUFACTURING COMPANYInventors: Pavel Farias, Gregg Krehel
