摘要:
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.

摘要:
A modular end effector delivers a therapeutic agent onto tissue that has been severed and/or stapled. The end effector is removably attached to a device. The device applies force to a piston of the end effector. The force causes a distal movement of a piston along a wall disposed within the end effector. The piston engages with agents stored on opposite sides of the wall, moving the agents distally to a mixture space. The agents are mixed in the mixture space and expelled through a tip. Staples may be embedded in or disposed below a foam block, which is disposed within a staple cartridge. Via an endoscopic stapling device, coated staples are driven through tissue while interacting with another agent on the device or the cartridge. The interaction forms a tissue restoring material that is applied onto the tissue.
