Abstract
A surgical staple. The staple can define a seamless unitary piece. In various instances, the staple can be formed and/or stamped from a sheet of material. The staple can include a base and staple legs. A staple drive surface can be integrally formed in the base, and a sled can directly contact the staple drive surface to directly drive the staple.
Claims22
A system, comprising:
- a seamless staple, comprising:
- a first leg
- a second leg, wherein the first leg and the second leg define a first plane;
- and
- an integral drive surface, wherein the integral drive surface extends along a longitudinal drive axis in a direction parallel to the first plane, and wherein the longitudinal drive axis is laterally offset from the first plane;
- and
- a sled comprising an inclined driving surface configured to directly contact the integral drive surface of the seamless staple, wherein the sled is configured to translate along a longitudinal axis to drive the seamless staple along a firing axis, and wherein the firing axis is transverse to the longitudinal axis.

A system, comprising:
- a surgical staple, comprising:
- a base comprising an inclined drive surface;
- a first leg extending from the base;
- and
- a second leg extending from the base, wherein the base, the first leg and the second leg define a seamless unitary piece, wherein the first leg and the second leg define a first plane, wherein the inclined drive surface extends along a longitudinal drive axis in a direction parallel to the first plane, and wherein the longitudinal drive axis is laterally offset from the first plane;
- and
- a sled configured to directly contact the inclined drive surface of the surgical staple, wherein the sled is configured to translate along a longitudinal axis to drive the surgical staple along a firing axis, and wherein the firing axis is transverse to the longitudinal axis.

A system, comprising:
- a surgical staple, comprising:
- a base;
- a first leg extending from the base;
- and
- a second leg extending from the base, wherein the base, the first leg and the second leg define a seamless unitary piece;
- wherein said base comprises:
- an inclined drive surface;
- a first portion comprising an initial drive surface, wherein the inclined drive surface is laterally offset from the initial drive surface, and wherein the first leg extends from the first portion;
- and
- a second portion, wherein the second leg extends from the second portion, and wherein the system further comprises:
- a sled configured to directly contact the inclined drive surface of the surgical staple, wherein the sled is configured to translate along a longitudinal axis to drive the surgical staple along a firing axis, and wherein the firing axis is transverse to the longitudinal axis.

A system, comprising:
- a surgical staple, comprising:
- a base comprising a drive surface;
- a first leg extending from the base;
- and
- a second leg extending from the base, wherein the first leg and the second leg define a first plane;
- wherein a longitudinal axis of the drive surface extends along a portion of the base in a direction parallel to the first plane, and wherein the longitudinal axis of the drive surface is laterally offset from the first plane;
- and
- a sled configured to directly contact the drive surface of the surgical staple.
5 more elements
A system, comprising:
- a surgical staple, comprising:
