摘要： A surgical staple includes first and second legs that are interconnected by a backspan. Each of the first and second legs defines a longitudinal leg axis and extends from the backspan along the leg axis to a tip. The tip is sharpened such that the tip is symmetrical about a longitudinal leg plane that includes the leg axis. In addition, a method of manufacturing a surgical staple includes sharpening a tip of a leg of the surgical staple such that the tip is symmetrical about a longitudinal leg axis that includes a longitudinal leg axis of the leg.

摘要： A surgical stapler includes a tubular body portion and a cartridge assembly disposed at a distal end of the body portion for expelling an annular array of staples. Each of the staples of the annular array of staples has a generally bent backspan. An anvil member disposed at the distal end of the tubular body portion is positioned opposite the cartridge assembly to clinch the staples in tissue upon expulsion of the staples from the cartridge assembly. The anvil member has a corresponding annular array of staple forming buckets. Each of the buckets is configured to accommodate the generally bent configuration of the staples to facilitate formation thereof.

摘要： Inserts and features to reduce or prevent spline crash in surgical staplers and/or to minimize damage resulting from spline crash in surgical staplers. An insert for a surgical stapler includes a body and spline covers. The body is configured to fit within a bore of a shell assembly and the spline covers extend inward from the body. Each of the spline covers are sized and dimensioned to cap a distal portion of splines of the shell assembly. A shell assembly for a surgical stapler includes shell splines that are disposed on an inner wall of an inner housing portion that defines a bore. The shell splines include a lead spline that has a leading end positioned distal of a leading end of each of the other shell splines.
