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, which comprises: a) a handle portion;b) a body extending distally from the handle portion and defining a longitudinal axis;c) a plurality of surgical clips disposed within the body;d) a jaw assembly mounted adjacent a distal end porti
1. An apparatus for application of surgical clips to body tissue, which comprises: a) a handle portion;b) a body extending distally from the handle portion and defining a longitudinal axis;c) a plurality of surgical clips disposed within the body;d) 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;e) a wedge plate longitudinally movable between the first and the second jaw portions; wherein said wedge plate biases the first and the second jaw portions when said wedge plate is longitudinally moved between the first and the second jaw portions;wherein said wedge plate maintains the first and the second jaw portions in the spaced-apart position and preventing flexing of the first and the second jaw portions during clip loading; andwherein said wedge plate has a first proximal window, said first proximal window to be engaged by a member disposed in said body, said member being configured to hold said wedge plate in a distal most position, said distal most position being between the first and the second jaw portions;f) a clip pusher configured to individually distally advance a surgical clip to the jaw assembly while the first and the second jaw portions are in the spaced-apart position;g) an actuator at least partially disposed within the body and longitudinally movable in response to actuation of the handle portion, the actuator having a cam link; andh) a jaw closure member positioned adjacent the first and second jaw portions to move the first and the second jaw portions from the spaced-apart position to the approximated position, wherein said cam link longitudinally moves said wedge plate between the first and the second jaw portions. 2. The apparatus of claim 1, wherein said wedge plate has a rounded distal tip. 3. The apparatus of claim 1, wherein said wedge plate has a second proximal window, said second proximal window adapted to be engaged by said member, said second proximal window configured to hold said wedge plate in a proximal most position being retracted from said first and said second jaw portions, said proximal most position of said wedge plate configured to allow the first and the second jaw from the spaced-apart position portions to be moved to the approximated position to compress said clip. 4. The apparatus of claim 3, wherein said first proximal window is connected to said second proximal window by a longitudinal slot. 5. The apparatus of claim 3, wherein said member is movable from said second proximal window to first proximal window by moving said wedge plate distally. 6. The apparatus of claim 1, wherein said cam link is engageable with a cam slot in said wedge plate, wherein said cam slot has a driving edge. 7. The apparatus of claim 1, wherein said member is a flexible leg. 8. An apparatus for application of surgical clips to body tissue, which comprises: a) a handle portion;b) a body extending distally from the handle portion and defining a longitudinal axis;c) a plurality of surgical clips disposed within the body;d) a jaw assembly mounted adjacent a distal end portion of the body, the jaw assembly including first and second law portions movable between a spaced-apart and an approximated position;e) a wedge plate longitudinally movable between the first and the second jaw portions;f) a clip pusher configured to individually distally advance a surgical clip to the jaw assembly while the first and the second jaw portions are in the spaced-apart position;g) an actuator at least partially disposed within the body and longitudinally movable in response to actuation of the handle portion, the actuator having a cam link; wherein said cam link is engageable with a cam slot in said wedge plate, wherein said cam slot has a driving edge;wherein said cam slot has a proximal side and a distal side, wherein at said distal side said cam link traverses past said driving edge at a demarcation line; andwherein at said demarcation line said cam link terminates distal movement of said wedge plate; andh) a jaw closure member positioned adjacent the first and the second jaw portions to move the first and the second jaw portions from the spaced-apart position to the approximated position, wherein said cam link longitudinally moves said wedge plate between the first and the second jaw portions. 9. The apparatus of claim 8, wherein said wedge plate further comprises a biasing device, and wherein at said demarcation line the disengagement between said cam link and said driving edge permits said biasing device to retract said wedge plate. 10. The apparatus of claim 9, wherein said wedge plate has a rounded distal end, wherein said cam link disengages said wedge plate at said demarcation line, and wherein the disengagement of said cam link permits retraction of said rounded distal end from between the first and the second jaw portions.
