a housing;
a firing member configured to be advanced during a firing motion;
a cavity, wherein the medical agent is housed in the cavity;
a passage in fluid communication with the cavity, wherein the passage includes an inlet for receiving the medical agent from the cavity, and an outlet for dispensing the medical agent; and
a movable member positioned within the housing, wherein the movable member is configured to motivate at least a portion of the medical agent from the cavity to the passage during the firing motion of the firing member.
2. The assembly of claim 1 , further comprising an actuation member actuatable to advance the firing member and move the movable member.
3. The assembly of claim 1 , wherein the housing is fixedly connected to a portion of the surgical instrument.
4. The assembly of claim 1 , further comprising a staple cartridge.
5. The assembly of claim 1 , wherein the firing member comprises a cutting member having a cutting surface.
6. The assembly of claim 1 , further comprising a medical agent storage unit, wherein the medical agent storage unit includes the cavity.
7. An assembly for a surgical instrument, wherein the surgical instrument is actuatable to deliver a medical agent, the assembly comprising:
a housing;
a firing member configured to be advanced during a firing motion;
a cavity, wherein the medical agent is housed in the cavity;
a passage in fluid communication with the cavity, wherein the passage includes an inlet for receiving the medical agent from the cavity, and an outlet for dispensing the medical agent; and
means for simultaneously firing the firing member and dispensing the medical agent.
8. The assembly of claim 7 , wherein the housing is fixedly connected to a portion of the surgical instrument.
9. The assembly of claim 7 , further comprising a staple cartridge.
10. The assembly of claim 7 , wherein the firing member comprises a cutting member having a cutting surface.
11. The assembly of claim 7 , further comprising a medical agent storage unit, wherein the medical agent storage unit includes the cavity.
12. A surgical instrument, comprising:
a housing;
a plurality of staples;
a firing member configured to fire the plurality of staples;
an agent cavity configured to house a medical agent therein;
a passage in fluid communication with the agent cavity, wherein the passage includes an inlet for receiving the medical agent from the agent cavity, and an outlet for dispensing the medical agent;
a movable member configured to move at least a portion of the medical agent from the agent cavity to the passage; and
an actuation member operably couplable to the firing member and the moveable member, wherein the actuation member is actuatable to fire the plurality of staples and dispense the medical agent simultaneously.
13. The surgical instrument of claim 12 , wherein the surgical instrument comprises a handle and an elongate body extending from the handle, and wherein the housing is configured to be releasably connected to the elongate body.
14. The surgical instrument of claim 12 , further comprising a staple cartridge, wherein the plurality of staples are at least partially supported by the staple cartridge, and wherein the staple cartridge is connected to the housing.
15. The surgical instrument of claim 12 , wherein the firing member comprises a cutting member having a cutting surface.
16. The surgical instrument of claim 12 , further comprising a medical agent storage unit, wherein the medical agent storage unit includes the agent cavity.
