Abstract
A surgical device having at least one rotary input screw in the end effector is provided. A rotary input screw can extend through a central longitudinal portion of the end effector. The end effector can include an improved closure system, firing systems, leveraging and alignment features between the staple cartridge and the surgical device, staple cartridges having multi-staple drivers, single-firing knife and lockout/safety features for the same, and/or modified staple patterns, for example. Certain components can be 3D-printed components.
Claims20
A linear fastener cartridge, comprising:
- a cartridge body comprising a tissue-supporting deck, wherein a longitudinal axis extends through the cartridge body;
- inner fastener cavities defined through the tissue-supporting deck into the cartridge body, wherein the inner fastener cavities are arranged in an inner longitudinal row on a first side of the longitudinal axis, and wherein the inner longitudinal row comprises an inner proximal-most fastener cavity;
- intermediate fastener cavities defined through the tissue-supporting deck into the cartridge body, wherein the intermediate fastener cavities are arranged in an intermediate longitudinal row on the first side of the longitudinal axis, and wherein the intermediate longitudinal row comprises an intermediate proximal-most fastener cavity;
- and
- outer fastener cavities defined through the tissue-supporting deck into the cartridge body, wherein the outer fastener cavities are arranged in an outer longitudinal row on the first side of the longitudinal axis, and wherein the outer longitudinal row comprises an outer proximal-most fastener cavity;
- drivers positioned in the inner fastener cavities, the intermediate fastener cavities, and the outer fastener cavities;
- and
- fasteners supported by the drivers, wherein each fastener comprises a crown comprising a proximal end and a distal end, a proximal leg extending from the proximal end, and a distal leg extending from the distal end, wherein the crowns define a uniform length across the inner longitudinal row, the intermediate longitudinal row, and the outer longitudinal row;
- wherein the inner proximal-most fastener cavity, the intermediate proximal-most fastener cavity, and the outer proximal-most fastener cavity is longitudinally offset, and wherein the inner proximal-most fastener cavity is longitudinally offset from the outer proximal-most fastener cavity by a longitudinal length that is less than half the uniform length of the crowns.

A linear fastener cartridge, comprising:
- a cartridge body comprising a tissue-supporting deck, wherein a longitudinal axis extends through the cartridge body;
- a first array of fastener cavities defined through the tissue-supporting deck into the cartridge body on a first side of the longitudinal axis, wherein the first array of fastener cavities comprises a first proximal-most fastener cavity;
- a second array of fastener cavities defined through the tissue-supporting deck into the cartridge body on a second side of the longitudinal axis, wherein the second array of fastener cavities comprises a second proximal-most fastener cavity;
- fasteners, wherein each fastener comprises a crown, a proximal leg extending from the crown, and a distal leg extending from the crown;
- and
- drivers supporting the fasteners, wherein each driver comprises:
- an inner support column;
- an intermediate support column;
- an outer support column;
- a first bridge connecting the inner support column and the intermediate support column;
- and
- a second bridge connecting the intermediate support column and the outer support column;
- wherein the first proximal-most fastener cavity is longitudinally offset from the second proximal-most fastener cavity by a distance.

A linear fastener cartridge, comprising:
- a cartridge body comprising a tissue-supporting deck, wherein a longitudinal axis extends through the cartridge body;
- an inner longitudinal row of fastener cavities on a first side of the longitudinal axis;
- an intermediate longitudinal row of fastener cavities on the first side of the longitudinal axis, wherein the intermediate longitudinal row of fastener cavities defines an intermediate axis parallel to the longitudinal axis;
- an outer longitudinal row of fastener cavities on the first side of the longitudinal axis, wherein the inner longitudinal row of fastener cavities and the outer longitudinal row of fastener cavities are asymmetric relative to the intermediate axis;
- triple drivers spanning the inner longitudinal row of fastener cavities, the intermediate longitudinal row of fastener cavities, and the outer longitudinal row of fastener cavities;
- and
- fasteners supported by the triple drivers, wherein each fastener comprises a crown comprising a proximal end and a distal end, a proximal leg extending from the proximal end, and a distal leg extending from the distal end, wherein the crowns define a uniform length across the inner longitudinal row, the intermediate longitudinal row, and the outer longitudinal row.
