Abstract

In various embodiments, a surgical system is disclosed. The surgical system comprises a medicament and a surgical instrument comprising a plurality of staples, a cavity configured to store the medicament, a delivery passage configured to convey the medicament from the cavity to tissue, and a firing system. The firing system comprises a movable member and a firing member, wherein the firing system is configured to cooperatively move the movable member and the firing member to concurrently fire the plurality of staples and deliver at least a portion of the medicament to the tissue owing to advancement of the firing member.

Claims

1. An end effector for use with a surgical instrument, the end effector comprising:

a plurality of staples;

an agent reservoir comprising a medical agent;

a dispensing passage configured to convey the medical agent from the agent reservoir to tissue; and

a firing system, comprising;

a cutting member;

a movable member; and

a firing member, wherein the firing system is configured to cooperatively move the movable member and the firing member to simultaneously fire the plurality of staples and dispense at least a portion of the medical agent near the cutting member owing to advancement of the firing member.

2. The end effector of claim 1, further comprising a staple cartridge, wherein the plurality of staples are at least partially stored within the staple cartridge.

3. The end effector of claim 2, further comprising an anvil, wherein at least one of the staple cartridge and the anvil is movable relative to the other.

4. The end effector of claim 1, wherein the cutting member comprises a cutting surface configured to cut tissue, and wherein the firing system is configured to dispense the at least a portion of the medical agent near the cutting surface.

5. A firing system for use with a surgical instrument, the firing system comprising:

a plurality of fasteners;

an agent cavity comprising a medical agent;

a delivery passage configured to convey the medical agent from the agent cavity to tissue; and

a firing system, comprising;

a cutting member;

a movable member; and

a firing member, wherein the firing system is configured to cooperatively move the movable member and the firing member to simultaneously fire the plurality of fasteners and deliver at least a portion of the medical agent to the tissue owing to advancement of the firing member.

6. The firing system of claim 5, further comprising a fastener cartridge, wherein the plurality of fasteners are at least partially stored within the fastener cartridge.

7. The firing system of claim 6, further comprising an anvil, wherein at least one of the fastener cartridge and the anvil is movable relative to the other.

8. The firing system of claim 5, wherein the cutting member comprises a cutting surface configured to cut tissue, and wherein the firing system is configured to dispense the at least a portion of the medical agent adjacent the cutting surface.

9. A surgical instrument, comprising:

a shaft; and

an end effector extending distally from the shaft, the end effector comprising;

a plurality of staples;

an agent reservoir comprising a medical agent;

a dispensing passage configured to convey the medical agent from the agent reservoir to tissue; and

a firing system, comprising;

a cutting member;

a movable member; and

a firing member, wherein the firing system is configured to cooperatively move the movable member and the firing member to simultaneously fire the plurality of staples and dispense at least a portion of the medical agent adjacent the cutting member as a result of the firing of the firing member.

10. The surgical instrument of claim 9, further comprising a handle extending proximally from the shaft, the handle including an actuation member actuatable to move the firing member and the movable member.

11. The surgical instrument of claim 9, wherein the end effector comprises a staple cartridge, wherein the plurality of staples are at least partially stored within the staple cartridge.

12. The surgical instrument of claim 11, wherein the end effector comprises an anvil, and wherein at least one of the staple cartridge and the anvil is movable relative to the other.

13. The surgical instrument of claim 9, wherein the cutting member comprises a cutting surface configured to cut tissue, and wherein the firing system is configured to dispense the at least a portion of the medical agent near the cutting surface.

14. A surgical system comprising:

a medicament; and

a surgical instrument comprising;

a plurality of staples;

a cavity configured to store the medicament;

a delivery passage configured to convey the medicament from the cavity to tissue; and

a firing system, comprising;

a movable member; and

a firing member, wherein the firing system is configured to cooperatively move the movable member and the firing member to concurrently fire the plurality of staples and deliver at least a portion of the medicament to the tissue owing to advancement of the firing member.

15. A surgical instrument, comprising:

a shaft;

an end effector extending distally from the shaft, the end effector comprising;

a plurality of fasteners;

an agent reservoir configured to store a medicament;

a dispensing passage configured to convey the medicament from the agent reservoir to tissue; and

a firing system, comprising;

a cutting member;

a movable member; and

a firing member, wherein the firing system is configured to cooperatively move the movable member and the firing member to concurrently fire the plurality of fasteners and dispense at least a portion of the medicament adjacent the cutting member as a result of the firing of the firing member.

16. The surgical instrument of claim 15, wherein the cutting member further comprises:

a cutting surface; and

a body comprising;

a first surface; and

a groove, wherein the groove is at least partially defined in the first surface and configured to be in fluid communication with the agent reservoir.

17. The surgical instrument of claim 16, wherein the groove is further configured to deliver the medicament from the agent reservoir to tissue.
