Abstract

A method for deforming a staple comprising a base, a first staple leg, and a second staple leg, wherein the base, the first staple leg, and the second staple leg are positioned within a common plane prior to being deformed, the method comprising positioning the first staple leg within a first cup of a staple pocket, the first cup comprising a first inner surface, applying a first compressive force to an end of the first staple leg to bend the first staple leg toward the base and the second staple leg, contacting the first inner surface with the end of the first staple leg to bend the end of the first staple leg toward a first side of the base, and deforming the first staple leg such that the end of the first staple leg crosses a mid-line of the staple defined between the first staple leg and the second staple leg.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This non-provisional patent application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61 / 250,377, entitled SURGICAL STAPLER, which was filed on Oct. 9, 2009, the entire disclosure of which is incorporated by reference herein.BACKGROUND[0002]i. Technical Field[0003]The present invention relates to stapling instruments and, in various embodiments, to a surgical stapling instrument for producing one or more rows of staples.[0004]ii. Background of the Related Art[0005]In recent years, there has been an increasing tendency for surgeons to use stapling instruments to suture body tissues such as a lung, an esophagus, a stomach, a duodenum and / or other organs in the intestinal tract. The use of an appropriate stapling instrument in many instances may perform a better job in less time and simplify previously difficult surgical procedures such as gastrointestinal anastomoses. Previous linear two and four row c...
