Abstract
An instrument is configured to receive a staple cartridge to staple tissue and expel a fluid from within a container in the staple cartridge. The staple cartridge has an upper deck including staple apertures and orifices formed therein. The orifices are in fluid communication with the containers. The staple cartridge includes staple drivers having a driver body to translate a staple and a container protrusion to expel the fluid out the orifices. The fluid may be expelled while driving the staples out through the staple apertures. The container may be vertically compressible container or, in one alternative, may be a container having a channel and a sealant that is configured to be pierced as the fluid is expelled. Some configurations for the fluid include a hemostatic agent, thrombin, a gel, or a medicament. The containers may also be formed as reservoirs defined within the upper deck and/or cartridge body.

19. A method for expelling a fluid from a staple cartridge using an instrument and a staple cartridge;
- wherein the instrument includes an end effector configured to receive a staple cartridge, the end effector having a staple forming pocket, wherein the staple cartridge includes an upper deck having a staple aperture and an orifice formed therethrough;
a container in fluid communication with the orifice;
a fluid disposed within the container;
a staple driver disposed within the staple cartridge and below the upper deck, the staple driver comprising a driver body and a container protrusion, the container protrusion slidably translatable within the container; and
a staple translatable by the staple driver, the method comprising;(a) inserting the staple cartridge into the end effector; (b) translating the staple driver and the staple in a substantially vertical direction; (c) driving the staple through the staple aperture and into the staple forming pocket; and (d) expelling the fluid out of the container by slidably translating the container protrusion within the container. - View Dependent Claims (20)
