ENDOSCOPIC SURGICAL CLIP APPLIER
First Claim
1. An apparatus for application of surgical clips to body tissue, the apparatus comprising:
- a handle portion;
a body extending distally from the handle portion and defining a longitudinal axis;
a jaw assembly mounted adjacent a distal end portion of the body, the jaw assembly including first and second jaw portions movable between a spaced-apart and an approximated position;
a jaw closure member positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position;
a plurality of surgical clips disposed within the body;
a clip pusher disposed proximal to the plurality of clips and configured to bias the plurality of clips in a distal manner;
a feed bar configured to individually distally advance a surgical clip to the jaw assembly while the jaw portions are in the spaced apart position;
a wedge plate longitudinally movable between the first and the second jaw portions; and
an actuator at least partially disposed within the body and longitudinally movable in response to actuation of the handle portion, wherein the actuator comprises a cam, and the wedge plate has a first cam slot and a first camming surface to engage with the cam to move the wedge plate distally between the first and second jaw portions upon a distal advancement of the actuator.

Abstract
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.

11. An apparatus for application of surgical clips to body tissue, the apparatus comprising:
-
a handle portion; a tubular member extending distally from the handle portion and defining a longitudinal axis, the tubular member being longitudinally fixed with respect to the handle portion, the tubular member being configured to rotate about the longitudinal axis; a spindle extending through the tubular member, the spindle having a proximal end and a distal end, the spindle being configured for movement along the longitudinal axis, the movement of the spindle defining a stroke, the stroke defining a predetermined distance of spindle travel from a proximal most position to a distal most position; a slider joint extending along the distal end of the spindle, the spindle being configured to provide movement of the slider joint along the longitudinal axis; a feed bar located within the tubular member and extending parallel to the longitudinal axis, the spindle being operatively connected with and configured to move the feed bar along the longitudinal axis; and a wedge plate located within the tubular member and extending parallel to the longitudinal axis, the spindle being operatively connected with and configured to move the wedge plate along the longitudinal axis. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
