An apparatus for application of surgical clips to body tissue includes a jaw assembly mounted adjacent a distal end portion of a body, the jaw assembly including first and second jaw portions movable between a spaced-apart and an approximated position; a yoke slidably supported at least partially in a handle portion and being connected to at least one trigger; a drive link slidably supported at least partially in the handle portion and the body, the drive link having a proximal end connected to the yoke; a spindle supported in the body and rotatably connected to the drive link; and a jaw closure member connected to a distal end of the spindle and being positioned adjacent the first and second jaw portions to move the jaw portions to the approximated position upon a squeezing of the at least one trigger which results in distal advancement of the jaw closure member.
1. An apparatus for application of surgical clips to body tissue, the apparatus comprising: a) an elongate body defining a longitudinal axis, the elongate body including a resilient member projecting therefrom;b) a jaw assembly mounted adjacent a distal end portion of the elongate body, the jaw asse
1. An apparatus for application of surgical clips to body tissue, the apparatus comprising: a) an elongate body defining a longitudinal axis, the elongate body including a resilient member projecting therefrom;b) a jaw assembly mounted adjacent a distal end portion of the elongate body, the jaw assembly including first and second jaw portions movable between a spaced-apart and an approximated position;c) a wedge plate longitudinally movable along the elongate body from a position proximal of the first jaw portion and the second jaw portion to a position between the first jaw portion and the second jaw portion, wherein said wedge plate biases the first and the second jaw portions apart when the a distal end of the wedge plate is longitudinally moved between the first and the second jaw portions; wherein the wedge plate maintains the first jaw portion and the second jaw portion in a fixed predetermined relationship during a loading of a clip into the first and second jaw portions, the fixed predetermined relationship preventing flexing of the first and second jaw portions during clip loading; andwherein the wedge plate has a first proximal window adapted to be engaged by the resilient member disposed in the elongate body, the resilient member being configured to hold the wedge plate in a distal-most position, the distal-most position of the wedge plate being the position between the first and the second jaw portions;d) an actuator at least partially disposed within the elongate body and longitudinally movable therewith, the actuator having a cam link, wherein said cam link engages the wedge plate to longitudinally move the distal end of the wedge plate between the first jaw portion and the second jaw portion; ande) a jaw assembly closure member positioned adjacent the first jaw portion and the second jaw portion to move the jaw portions to the approximated position following a retraction of the distal end of the wedge plate from between the first jaw portion and the second jaw portion. 2. The apparatus of claim 1, wherein the distal end of the wedge plate is a rounded distal tip. 3. The apparatus of claim 1, wherein the wedge plate has a second proximal window, the second proximal window adapted to be engaged by the resilient member, the second proximal window of the wedge plate being configured to hold the wedge plate in a proximal-most position retracted from between the first jaw portion and the second jaw portion, the proximal-most position of the wedge plate allowing the first jaw portion and the second jaw portion to be moved to the approximated position to form a clip loaded therebetween. 4. The apparatus of claim 3, wherein upon movement of the wedge plate in a distal direction, the resilient member is moved from disposition within the second proximal window to disposition within the first proximal window. 5. The apparatus of claim 1, wherein the cam link is engageable with a cam slot formed in the wedge plate, wherein the cam slot defines a driving edge. 6. The apparatus of claim 1, further comprising: a plurality of surgical clips disposed within the elongate body; anda clip pusher slidably disposed within the elongate body, wherein the clip pusher is configured to individually distally advance a single surgical clip into the jaw assembly while the first jaw portion and the second jaw portion are in the spaced apart position. 7. The apparatus of claim 1, further comprising: a handle portion, wherein the elongate body extends from the handle portion, and wherein and actuator is longitudinally movable in response to actuation of the handle portion. 8. The apparatus of claim 1, wherein the wedge plate includes a cam slot formed therein, wherein the cam slot includes a proximal side and a distal side, and wherein the cam slot defines a driving edge, wherein at the distal side of the cam slot the cam link traverses past the driving edge at a demarcation line; and wherein at the demarcation line the cam link terminates distal movement of the wedge plate. 9. The apparatus of claim 8, wherein the wedge plate further comprises a biasing device, and wherein at the demarcation line the disengagement between the cam link and the driving edge permits the biasing device to retract the wedge plate. 10. The apparatus of claim 9, wherein the cam link disengages the wedge plate at the demarcation line, and wherein the disengagement of the cam link permits retraction of the distal end of the wedge plate from between the first jaw portion and the second jaw portion. 11. The apparatus of claim 1, further comprising a filler component fixedly disposed within the elongate body and disposed adjacent the wedge plate, the filler component defining a cam slot having a disengaging edge formed therealong, wherein the cam link engages the disengaging edge of the cam slot in the filler component, upon a movement of the actuator, to allow distal movement of the wedge plate.
