Surgical stapling device with adjunct material application feature
First Claim
1. A surgical instrument apparatus comprising:
- (a) a handle portion;
(b) a shaft housing a firing bar;
(c) 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; and
(d) a removable cartridge, wherein the lower jaw is configured to receive the cartridge, the cartridge comprising;
(i) a housing,(ii) a plurality of staples disposed in the housing,(iii) a deck disposed over the plurality of staples, the deck defining a plurality of apertures, each aperture being substantially disposed over each staple, and(iv) a biocompatible material, wherein the firing bar is operable to apply the biocompatible material to tissue while the stapling and severing assembly simultaneously severs and drives staples into the tissue, wherein the firing bar includes a notch configured to receive the biocompatible material.

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 removable cartridge. 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 includes an agent. The firing bar is operable to assist with releasing the agent onto a severed line of tissue when the firing bar is advanced.

15. A method of releasing material from a surgical instrument, the surgical instrument including an end effector, a handle portion, and a shaft housing a firing bar, the end effector including a lower jaw and an anvil, the lower jaw being configured to receive a removable cartridge, the cartridge including a deck having a vertical slot, the instrument further including a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft, the stapling and severing assembly including the firing bar, the method comprising the steps of:
-
(a) inserting the cartridge comprising a biocompatible material in the lower jaw of the end effector such that the biocompatible material is retained within a notch in the firing bar when the firing bar is in a first position; and (b) producing the longitudinal closing motion to advance the firing bar of the stapling and severing assembly through the vertical slot of the deck of the cartridge to a second position, such that the advancement of the firing bar concurrently advances the retained biocompatible material. - View Dependent Claims (16, 17)
