Patent number: 8579918Abstract: An apparatus for application of surgical clips to body tissue has a handle portion; a body extending distally from the handle portion; a plurality of surgical clips disposed within the body; and a jaw assembly mounted adjacent a distal end portion of the body. The jaw assembly includes first and second jaw portions movable between a spaced-apart and an approximated position. The apparatus also has a wedge plate longitudinally movable between the first and the second jaw portions, a clip pusher configured to individually distally advance a surgical clip to the jaw assembly while the jaw portions are in the spaced apart position; an actuator at least partially disposed within the body and longitudinally movable in response to actuation of the handle portion; and a jaw closure member positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position.Type: GrantFiled: May 17, 2010Date of Patent: November 12, 2013Assignee: Covidien LPInventors: Kenneth H.

Patent number: 8282655Abstract: A surgical clip applying apparatus includes a movable member biased in the housing adjacent the wedge plate. An actuator longitudinally advances the wedge plate a predetermined distance to a distal most position. The wedge plate has an end being disposed between first and second jaw portions at the distal most position. The wedge plate end is configured to maintain the jaw assembly in the spaced apart position during loading of the surgical clip and reduce torque and external forces on the jaw assembly during the loading. The movable member holds the wedge plate in the distal most position during the loading and the movable member is deflected at a conclusion of the loading, releases the wedge plate upon deflection, and allows a longitudinal proximal retraction of the wedge plate from the distal most position.Type: GrantFiled: December 23, 2009Date of Patent: October 9, 2012Assignee: Tyco Healthcare Group LPInventors: Kenneth H. Whitfield, Greg Sorrentino
