Patent number: 11712288Abstract: An end effector apparatus for a surgical instrument is disclosed including a housing having a first jaw mounted on a revolute joint and providing a first electrical conduction path between the housing and the first jaw. A second jaw is mounted on a revolute joint within the housing and is insulated from the housing, the jaws each having a manipulating portion and a lever arm. A yoke is received within the housing and mechanically coupled to the lever arms and to a control link and is moveable in response to movements of the control link to cause opening and closing of the jaws, the yoke being electrically insulated from the housing and the first jaw. A second electrical conduction path is provided between the control link and the second jaw. The electrical conduction paths facilitate conduction of an electrocauterization current through tissue grasped between the jaws.Type: GrantFiled: October 7, 2020Date of Patent: August 1, 2023Assignee: TITAN MEDICAL INC.Inventors: Rene Robert, Jonathan Hess Hills, Timothy Norman Johnson

Patent number: 9327782Abstract: A fifth wheel includes a top plate having a throat that is adapted to receive a kingpin of a trailer. The fifth wheel is equipped with a locking mechanism including a jaw slidably connected to the top plate and slidable between a closed position where the jaw blocks passage of a kingpin out of the throat of the fifth wheel and an open position where a kingpin may pass into and out of the throat of the fifth wheel. The jaw has an edge adapted to engage a kingpin positioned in the throat of the fifth wheel when the jaw is in the closed position. A bias device urges the jaw towards the closed position. The fifth wheel further includes a mechanism for moving the jaw between the open and closed positions. Further, the top plate of the fifth wheel is configured to allow service and/or replacement of the jaw from the top of the fifth wheel while it is assembled to a vehicle.Type: GrantFiled: June 24, 2014Date of Patent: May 3, 2016Assignee: Fontaine Fifth WheelInventors: Steven Michael Alldredge, Robert Todd Shelton, Charles Leon Rosato, Timothy Norman Johnson, James H.
