Abstract
A stapling system includes a tissue staple, a mandrel, and a pusher. The staple includes a crown at the proximal end and a plurality of prongs extending distally therefrom about a central axis of the staple. Each prong of the staple includes a tab extending towards the central axis. The mandrel receives the staple along an outer surface thereof. The mandrel includes a proximal groove adapted to receive the tab of the corresponding prong. The proximal groove includes a ramp from a proximal portion of the proximal groove to a distal portion of the proximal groove. The mandrel further includes a distal groove adapted to receive the tabs of the prongs and a distal anvil disposed distally of the distal groove. The pusher is disposed around the mandrel abutting and proximal to crown of the staple.
