Abstract

A surgical stapling assembly is disclosed. The surgical stapling assembly can include a first jaw, a second jaw, an articulation joint, a closure drive comprising a first flexible rotary drive extending through the articulation joint, and a firing drive comprising a second flexible rotary drive extending through the articulation joint and rotatable independent of the first flexible rotary drive. The surgical stapling assembly can further include a 3D-printed component.

Claims20

Dependent claims

A surgical stapler, comprising:

(a) a staple cartridge, comprising:
(i) a cartridge body having a deck configured to support tissue and extending along a longitudinal axis that divides the deck into a first deck side and a second deck side,
(ii) a first pattern of staple cavities disposed on the first deck side and configured to house a first plurality of staples, and
(iii) a second pattern of staple cavities disposed on the second deck side and configured to house a second plurality of staples,
wherein the first and second patterns of staple cavities are asymmetric about the longitudinal axis;
and
(b) an anvil configured to cooperate with the staple cartridge to clamp and staple tissue, wherein the anvil includes a plurality of forming pockets configured to:
(i) form at least one staple of at least one of the first or second pluralities of staples with a planar staple configuration, and
(ii) form at least one staple of at least one of the first or second pluralities of staples with a non-planar staple configuration.

A surgical stapler, comprising:

(a) a staple cartridge, comprising:
(i) a cartridge body having a deck configured to support tissue and extending along a longitudinal axis that divides the deck into a first deck side and a second deck side,
(ii) a first pattern of staple cavities disposed on the first deck side and configured to house a first plurality of staples, and
(iii) a second pattern of staple cavities disposed on the second deck side and configured to house a second plurality of staples,
wherein each of the first and second patterns of staple cavities includes:
(A) an inner row of staple cavities extending along an inner row axis,
(B) an intermediate row of staple cavities extending along an intermediate row axis, and
(C) an outer row of staple cavities extending along an outer row axis,
wherein a lateral spacing between the inner row axis and the intermediate row axis differs from a lateral spacing between the intermediate row axis and the outer row axis;
and
(b) an anvil configured to cooperate with the staple cartridge to clamp and staple tissue, wherein the anvil includes a plurality of forming pockets configured to:
(i) form at least one staple of each of the first and second pluralities of staples with a planar staple configuration, and
(ii) form at least one staple of each of the first and second pluralities of staples with a non-planar staple configuration.

10 more elements

A surgical stapler, comprising:

(a) a staple cartridge, comprising:
(i) a cartridge body defining a deck configured to support tissue,
(ii) a longitudinal slot extending along a longitudinal axis of the cartridge body and dividing the deck into a first deck side and a second deck side,
(iii) a plurality of staple cavities configured to house staples, including:
(A) a first pattern of staple cavities disposed on the first deck side, and
(B) a second pattern of staple cavities disposed on the second deck side,
wherein each of the first and second patterns of staple cavities includes:
(1) a first row of staple cavities, and
(2) a second row of staple cavities laterally outward of the first row of staple cavities,
(iv) a plurality of staple drivers slidably housed within the staple cavities of the first and second patterns and configured to engage the staples, and
(v) a sled slidably coupled with the cartridge body and configured to advance distally along the longitudinal axis to actuate the staple drivers and thereby eject the staples from the first and second patterns of staple cavities;
and
(b) an anvil configured to cooperate with the staple cartridge to clamp and staple tissue, wherein the anvil includes a plurality of forming pockets configured to:
(i) form at least one staple housed within the first row of each of the first and second patterns of staple cavities with a planar staple configuration, and
(ii) form at least one staple housed within the second row of each of the first and second patterns of staple cavities with a non-planar staple configuration.
