A surgical staple for use in joining the skin or fascia of a patient. The staple is adapted to be formed about an anvil during emplacement. The staple has points formed by diagonal cuts across the ends, and its configuration prior to emplacement is such, that the diagonal cuts are perpendicular to the upper surface of the anvil and the skin or fascia, whereby the staple penetrates the skin or fascia without the tendency to slide therealong. The configuration is such that at initial contact of the staple points with the skin or fascia, the points lie substantially in the plane of the forming corners of the anvil, thereby affording greater skin gathering during emplacement. The configuration disclosed facilitates stacking of the staples for use in a cartridge, and provides for an improvement in the space factor within the cartridge over staples of conventional shape.
