ABSTRACT:
A disposable surgical stapling instrument is taught for forming and implanting surgical staples in the skin or fascia of a patient. The instrument comprises a body made up of two mating halves and having a rear handle portion, a forward portion and a staple magazine portion beneath the forward portion. The forward portion of the body houses a staple driver shiftable therein between a first retracted position and a second extended staple forming and implanting position. A trigger is pivotally mounted within the body and is directly connected to the staple driver to shift the driver between its first and second positions. A portion of the trigger is exposed beneath the body handle portion for actuation by the surgeon. A leaf spring is located within the body above the trigger to urge the trigger to its unactuated position and the staple driver to its first position. The magazine portion houses an anvil plate terminating at its forward end in a coextensive anvil surface located beneath the staple driver. The anvil plate is configured to support the legs of all but the forwardmost staple of a row thereof mounted thereon. The magazine portion also houses a feeder assembly for the row of staples.
