Abstract

A method of operating a surgical instrument includes clamping tissue with a surgical instrument end effector and actuating the end effector to drive staples into the clamped tissue, including a first longitudinal row having at least one first formed staple with a first formed shape in which the first legs are aligned laterally with each other and with the first crown; a second longitudinal row having at least one second formed staple with a second formed shape in which each second leg is skewed laterally away from the second crown at a first angle; and a third longitudinal row of third formed staples having at least one third formed staple with a third formed shape in which each third leg is skewed laterally away from the third crown at a second angle.

Claims (17)

1 . A method of operating a surgical instrument, comprising:

(a) clamping tissue between first and second jaws of an end effector of the surgical instrument; and

(b) actuating the end effector to drive a plurality of staples into the clamped tissue and thereby apply:

(i) a first longitudinal row of first formed staples each having a first crown and a pair of first legs, wherein at least one first formed staple has a first formed shape in which the first legs are aligned laterally with each other and with the first crown,

(ii) a second longitudinal row of second formed staples each having a second crown and a pair of second legs, wherein at least one second formed staple has a second formed shape in which each second leg is skewed laterally away from the second crown at a first angle, and

(iii) a third longitudinal row of third formed staples each having a third crown and a pair of third legs, wherein at least one third formed staple has a third formed shape in which each third leg is skewed laterally away from the third crown at a second angle.

2 . The method of claim 1 , wherein the end effector extends along a longitudinal axis, wherein each of the first longitudinal row of first formed staples, the second longitudinal row of second formed staples, and the third longitudinal row of third formed staples is arranged on the same lateral side of the longitudinal axis.

3 . The method of claim 2 , wherein the first longitudinal row of first formed staples is laterally outward of the longitudinal axis, the second longitudinal row of second formed staples is laterally outward of the first longitudinal row of first formed staples, and the third longitudinal row of third formed staples is laterally outward of the second longitudinal row of second formed staples.

4 . The method of claim 3 , wherein the second angle is greater than the first angle.

5 . The method of claim 2 , wherein each of the first crown of the at least one first formed staple, the second crown of the at least one second formed staple, and the third crown of the at least one third formed staple is substantially parallel to the longitudinal axis.

6 . The method of claim 5 , wherein each first formed staple has the first formed shape, each second formed staple has the second formed shape, and each third formed staple has the third formed shape.

7 . The method of claim 6 , wherein each first formed staple is longitudinally aligned with a respective third formed staple, wherein each second formed staple is longitudinally offset from each first formed staple and each third formed staple.

8 . The method of claim 7 , wherein the first longitudinal row of first formed staples, the second longitudinal row of second formed staples, and the third longitudinal row of third formed staples are arranged on a first lateral side of the longitudinal axis, wherein the plurality of staples further comprises:

(i) a fourth longitudinal row of fourth formed staples each having the first formed shape,

(ii) a fifth longitudinal row of fifth formed staples each having the second formed shape, and

(iii) a sixth longitudinal row of sixth formed staples each having the third formed shape,

wherein the fourth longitudinal row of fourth formed staples, the fifth longitudinal row of fifth formed staples, and the sixth longitudinal row of sixth formed staples are arranged on a second lateral side of the longitudinal axis.
