Abstract

A surgical instrument includes a stapling assembly and an anvil that releasably couple together to compress and staple tissue. The stapling assembly includes a body having a longitudinal axis, a deck member, and a knife member surrounding the longitudinal axis. The deck member includes a deck surface having an imaginary centerline that surrounds the longitudinal axis, a first deck surface portion extending along a first angular range of the deck surface about the longitudinal axis, and a second deck surface portion extending along a second angular range of the deck surface about the longitudinal axis. A first array of staple openings is disposed on the first deck surface portion and is arranged in a first orientation relative to the deck surface centerline. A second array of staple openings is disposed on the second deck surface portion and is arranged in a second orientation relative to the deck surface centerline.

Claims19

Dependent claims

A surgical instrument comprising:

(a) a stapling assembly including:
(i) a body extending distally along a longitudinal axis,
(ii) a deck member disposed at a distal end of the body and defining a deck surface having a deck surface centerline that surrounds the longitudinal axis, wherein the deck surface includes:
(A) a first deck surface portion extending along a first angular range of the deck surface about the longitudinal axis, wherein the first deck surface portion is wholly positioned within a first deck plane,
(B) a second deck surface portion extending along a second angular range of the deck surface about the longitudinal axis, wherein the second deck surface portion includes a linear shape and is wholly positioned within a second deck plane,
(C) a first array of staple openings disposed on the first deck surface portion and arranged in a first orientation relative to the deck surface centerline, and
(D) a second array of staple openings disposed on the second deck surface portion and arranged in a second orientation relative to the deck surface centerline, wherein the second orientation is different than the first orientation, and
(iii) a knife member disposed within the body and surrounding the longitudinal axis;
and
(b) an anvil configured to releasably couple with the stapling assembly to compress tissue against the deck member and form staples in the tissue.

wherein the first deck surface portion and the third deck surface portion are opposed about the longitudinal axis,
wherein the second deck surface portion and the fourth deck surface portion are opposed about the longitudinal axis,
wherein the second and fourth deck surface portions are sloped at a constant angle relative to the longitudinal axis between the first deck surface portion and the third deck surface portion,
wherein the staple openings of the first array and the third array are arranged in a first orientation relative to the deck surface centerline,
wherein the staple openings of the second array and the fourth array are arranged in a second orientation relative to the deck surface centerline, wherein the second orientation is different than the first orientation, and
(iii) a knife member disposed within the body and surrounding the longitudinal axis;
and
(c) an anvil configured to releasably couple with the stapling assembly to compress tissue against the deck member and form staples in the tissue.
