ABSTRACT:
A multi-staple cartridge for surgical staplers in which individual staples are retained and driven by separate but commonly actuated staple retaining units. Each of the units includes a movable staple carrier and a staple driving head. All units are actuated by a cartridge contained driving press so that the driving head and carrier are first moved together under a limited or yieldable force transmitting means tending to retain them in their initial relative position. The force transmitting means operative between the common driving press then advances the driving head relative to the carrier to set the staple. Final movement of the carrier and driving head is by direct abutting engagement with the driving press for all staples not previously clinched by the force of the yieldable force transmitting means. Tissue thickness variation is thus accommodated by each individual staple.
