Abstract
A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a cartridge when in an open position. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The cartridge further receives a matrix including glue beads suspended in the matrix. The staples are driven through the matrix to secure the matrix to tissue. The glue beads are activated when the matrix is secured to the tissue, such that the activated adhesive further secures the staple line in the tissue.

16. A method of releasing and activating adhesive with a surgical instrument, the surgical instrument including an end effector, a handle portion, a shaft, a stapling and severing assembly, a matrix, and a removable cartridge, wherein the end effector comprises a lower jaw and an anvil, the lower jaw being configured to receive a removable cartridge, wherein the stapling and severing assembly is responsive to a longitudinal closing motion produced by the handle portion and the shaft, wherein the matrix includes glue beads suspended in the matrix, wherein the cartridge includes an exterior top surface, wherein a first portion of the matrix is disposed on the exterior top surface of the cartridge, the method comprising the steps of:
-
(a) disposing the matrix on the end effector of the surgical instrument between the lower jaw and the anvil; (b) activating the stapling and severing assembly to drive staples through the matrix; and (c) applying at least one of heat or moisture to the matrix to an amount sufficient to activate the glue beads suspended in the matrix. - View Dependent Claims (17, 18, 19)

20. A surgical instrument comprising:
-
(a) a handle portion; (b) a shaft, the shaft housing a firing bar; (c) a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft; (d) a staple cartridge, wherein the staple cartridge comprises; (i) a plurality of staples, and (ii) a deck disposed over the plurality of staples, the deck defining apertures, each aperture being substantially disposed over at least one respective staple; (e) an end effector connected to the shaft, the end effector comprising an anvil and a lower jaw, the cartridge being received in the lower jaw, the anvil being configured to form the staples in response to a longitudinal closing motion when the end effector is in a closed position; and (f) a biocompatible material containing glue beads suspended in a matrix, the biocompatible material being releasably attached to the cartridge and the anvil; wherein the staples are operable to be driven through the biocompatible material.
