Abstract
An apparatus includes an end effector including an anvil and lower jaw. The anvil is pivotable toward the lower jaw to capture tissue. The apparatus further includes a stapling and severing assembly configured to sever and staple tissue clamped between the anvil and the lower jaw. A staple cartridge is coupled with the lower jaw. The staple cartridge includes a deck facing the anvil, a plurality of staples positioned in a plurality of staple openings formed through the deck, and a magnetic feature configured to be coupled to tissue in response to activation of the stapling and severing mechanism. The magnetic feature is configured to be coupled to tissue in response to actuation of the staple cartridge, wherein the magnetic feature is configured to retain at least one outer portion of stapled tissue in an inwardly folded position relative to an inner portion of stapled tissue.

17. A method of operating on tissue using a circular stapler, wherein the circular stapler comprises an anvil, and a stapling head assembly, wherein the stapling head assembly includes a rod, a knife member, and a staple driver, wherein the knife member is configured to provide a circular cut line, wherein the anvil and the stapling head assembly are configured to cooperate to clamp and staple tissue, wherein the method comprises:
-
(a) severing and stapling a first portion of anatomical structure using a non-circular stapler, thereby leaving a plurality of staples and a first magnetic feature on a severed end portion of the first portion of anatomical structure; (b) inserting the anvil of the circular stapler into a second portion of anatomical structure; (c) inserting the stapling head assembly into the first portion of anatomical structure until at least a portion of the rod extends past the severed end portion of the first portion of anatomical structure; (d) drawing the first magnetic feature inwardly toward the rod such that the first magnetic feature magnetically couples with a second magnetic feature, thereby holding the plurality of staples on the severed end portion at a position inward of the cut line of the knife member; (e) coupling the rod and the anvil; (f) clamping the first and second portions of anatomical structure together between the anvil and the sapling head assembly; (g) directing the drivable knife member toward the anvil, thereby severing the severed end portion and the staples from the first portion of anatomical structure and at least part of the second portion of anatomical structure; and (h) stapling the first and second portions of anatomical structure together using the staple driver. - View Dependent Claims (18, 19)

20. A method of operating on tissue using a circular stapler, wherein the circular stapler comprises an anvil, and a stapling head assembly, wherein the stapling head assembly includes a rod, a knife member, and a staple driver, wherein the knife member is configured to provide a circular cut line, wherein the anvil and the stapling head assembly are configured to cooperate to clamp and staple tissue, wherein the method comprises:
-
(a) severing and stapling a first portion of the colon using a non-circular stapler, thereby leaving a first plurality of staples and a first magnetic feature on a first severed end portion of the first portion of the colon; (b) severing and stapling a second portion of the colon using a non-circular stapler, thereby leaving a second plurality of staples on a second severed end portion of the second portion of the colon; (c) inserting the anvil of the circular stapler into the second portion of the colon; (d) inserting the stapling head assembly into the first portion of the colon until at least a portion of the rod extends past the severed end portion of the first portion of the colon; (e) drawing the first severed end portion inward toward the rod such that the first plurality of staples and the first severed end portion lie radially inwardly of the cut line of the knife member and the first magnetic feature couples to a second magnetic feature; (f) directing the drivable knife member toward the anvil, thereby severing the first severed end portion and the first plurality of staples from the first portion of the patient'"'"'s colon and at least part of the second portion of the patient'"'"'s colon; and (g) stapling the first and second portions of the colon together.
