Abstract

An apparatus includes a body, a shaft, a stapling head assembly, and an anvil. The body includes a motor, a first user input feature, and a second user input feature. The first user input feature is operable to activate the motor. The shaft extends distally from the body. The stapling head assembly is positioned at a distal end of the shaft. The stapling head assembly includes an anvil coupling feature, at least one annular array of staples, and a staple driver. The second user input feature is operable to drive the anvil coupling feature longitudinally. The staple driver is operable to drive the at least one annular array of staples. The motor is operable to drive the staple driver. The anvil is configured to couple with the anvil coupling feature. The anvil is further configured to deform the staples driven by the staple driver.

Claims19

Dependent claims

An apparatus comprising:

(a) an anvil coupling feature extending along a longitudinal axis, wherein the anvil coupling feature is configured to couple with a surgical stapling head assembly;
and
(b) an anvil surface configured to compress tissue against a deck surface of the surgical stapling head assembly, wherein the anvil surface defines:
(i) an inner annular array of staple forming pockets, wherein the inner annular array of staple forming pockets comprises a plurality of staple forming pocket pairs, wherein each pair of staple forming pockets in the inner annular array comprises:
(A) a first staple forming pocket that includes a center of a staple entry region and a center of an opposing staple exit region that collectively extend along a first axis, and
(B) a second staple forming pocket that includes a center of a staple entry region and a center of an opposing staple exit region that collectively extend along a second axis, and
(ii) an outer annular array of staple forming pockets, wherein the outer annular array of staple forming pockets comprises a plurality of staple forming pocket pairs, wherein each pair of staple forming pockets in the outer annular array comprises:
(A) a first staple forming pocket that includes a center of a staple entry region and a center of an opposing staple exit region that collectively extend along a third axis, and
(B) a second staple forming pocket that includes a center of a staple entry region and a center of an opposing staple exit region that collectively extend along a fourth axis, wherein the first, second, third, and fourth axes extend parallel to each other.
