Abstract

An end effector for stapling and cutting an anatomical structure includes an anvil, a cartridge, and a blade. The anvil has an anvil face and a plurality of staple pockets positioned on the anvil face. The cartridge has a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples. Each of the plurality of staples comprises a first staple leg, a second staple leg, and a crown connecting the first and second staple legs and having a midpoint. Each of the plurality of staples comprises an open staple configuration and a closed staple configuration where a first portion of the first staple leg and a second portion of the second staple leg are bent relative to the crown such that the first portion of the first staple leg and the second portion of the second staple leg cross the midpoint of the crown.

Claims24

Dependent claims

An end effector for stapling and cutting an anatomical structure, the end effector comprising:

(a) an anvil, the anvil comprising;
(i) a first anvil end, a second anvil end, and an anvil face;
and
(b) a cartridge having a first cartridge end, a second cartridge end, and a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples, wherein the first anvil end is coupled with the first cartridge end at a distal portion of the end effector and the second anvil end is coupled with the second cartridge end at a proximal portion of the end effector, wherein each of the plurality of staples comprises a first staple leg having a first tip, a second staple leg having a second tip, and a crown connecting the first staple leg and the second staple leg and having a midpoint, wherein actuating the end effector moves each of the plurality of staples from;
(i) an open staple configuration wherein the first staple leg and the second staple leg are generally perpendicular to a longitudinal axis of the crown;
(ii) a closed staple configuration wherein a first portion of the first staple leg and a second portion of the second staple leg overlap and cross the midpoint of the crown, and wherein the first tip and the second tip remain above and to a same side of the crown;
and
(c) a blade that is movable from a first position at the first anvil end to a second position at the second anvil end.
