METHOD OF APPLYING STAPLES TO LIVER AND OTHER ORGANS

摘要

A method for treating a patient includes a surgical instrument having a handle assembly, a shaft assembly, and an end effector. The end effector includes an upper jaw and a lower jaw configured to pivot to receive a tissue of the patient therebetween. The upper and lower jaws respectively have upper and lower crush surfaces, which extends generally parallel with a centerline and are configured to receive the tissue thereagainst. The upper jaw also includes an anvil, whereas the lower jaw includes a staple cartridge and a deck facing the anvil. In addition, the lower jaw has a plurality of staple opening formed through the deck with a plurality of staples received therein. The upper and lower crush surfaces are configured to compress the tissue therebetween with a crush pressure configured to sever the tissue along the upper and lower crush surfaces.

1. A method of operating on tissue, comprising:
(a) positioning tissue between a first jaw and a second jaw of an end effector, wherein the first jaw comprises a plurality of staples, wherein the second jaw comprises a plurality of staple forming features, wherein the end effector is in an open configuration during the act of positioning tissue between the first jaw and the second jaw; (b) compressing the tissue between the first jaw and the second jaw, wherein the act of compressing the tissue provides dissection of at least some of the compressed tissue, wherein the dissected tissue reveals a vessel or duct; and (c) actuating the end effector to drive one or more of the staples through the revealed vessel or duct, thereby ligating the revealed vessel or duct.
