Surgical Stapling System

摘要: A system is provided for joining two tubular structures by a surgical stapling procedure. The includes series of sizers, specifically designed graft, loading unit, wand, tourniquet, and instrument. sizers are determining the diameter target aorta availability sufficient transected aortic length to perform unit holds graft in position body deploys circumferential line staples through an overlapping end aorta. side port which during procedure, may be closed once procedure has been completed. wand used introduce into body, them within aorta, hold place application tourniquet. tourniquet band formed from flexible material having width greater than its thickness so as facilitate formation annular loop. With holding relative positions, removed instrument plurality anvils, form circle overlying trigger mechanism firing staples. When fired, deployed radially outward whereupon their free ends bent inwardly staple returns on anvils. As result, simultaneously quickly accurately pattern join together structures. either open or laparascopically.
