Endoscopic surgical clip applier

摘要

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.

主权项

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; and h) 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.
