ABSTRACT:
A magazine fed, trigger driven surgical stapler to close a surgical incision. The stapler has an anvil and a staple driving die, an adjustable stop for controlling movement of the staple driving die so that staples can be reformed to a range of closed positions. The anvil is pivotable under control of the staple driving die between a staple engaging position and position clear of the staples. A forcep assembly operable under actuation control of the staple driving die acts to draw the edges of the incision into close approximation. A staple blank with a concave back, upper arms extending the concave shape of the back and pointed lower arms extending downwardly and inwardly from the upper arms, which blank on reformation around the anvil will adopt a substantially hexagonal configuration.
