Abstract

In various embodiments, an assembly of a surgical instrument is disclosed. The assembly includes a housing, a cutting member relatively movable with respect to the housing, and an agent cartridge connected to the housing. The agent cartridge houses a medical agent. The assembly is configured to deliver the medical agent proximate a cutting surface of the cutting member.

Claims

1. An assembly of a surgical instrument, comprising:

a housing;

a cutting member relatively movable with respect to the housing, wherein the cutting member comprises a cutting surface, a body including a first surface, and a groove at least partially defined by the first surface; and

an agent cartridge connected to the housing, wherein the agent cartridge includes a cavity configured to house a medical agent therein, wherein the cutting member groove is in fluid communication with the cavity, and wherein said cutting member is configured to movably interact with said agent cartridge such that movement of said cutting member relative thereto in a first direction causes said medical agent housed within said cavity to be delivered through the groove and dispensed proximate to the cutting surface.

2. The assembly of claim 1, wherein the agent cartridge comprises a body, and wherein the agent cartridge body and the cutting member groove define a passage therebetween configured to deliver the medical agent from the cavity proximate to the cutting surface.

3. The assembly of claim 1, wherein the agent cartridge includes a dispensing port in fluid communication with the cavity, and wherein the groove is configured such that it remains in fluid communication with the dispensing port as the cutting member is moved relative to the housing.

4. The assembly of claim 1, 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.

5. The assembly of claim 1, wherein the housing is fixedly connected to a portion of the surgical instrument.

6. The assembly of claim 1, wherein the agent cartridge is directly connected to the housing.

7. The assembly of claim 1, further comprising a staple cartridge connected to the housing.

8. The assembly of claim 1, further comprising a medical agent driver extending from the cutting member, wherein the driver is configured to engage the agent cartridge and dispense the medical agent from the agent cartridge cavity to the groove as the cutting member is moved relative to the housing.

9. An assembly of a surgical instrument, comprising:

a housing;

a member relatively movable with respect to the housing, wherein the member comprises a cutting surface, a body including a first surface, and a passage at least partially defined by the first surface; and

an agent cartridge, wherein the agent cartridge includes a medical agent storage portion configured to house a medical agent therein, wherein the member passage is in fluid communication with the medical agent storage portion, and wherein said movable member is configured to movably interact with said medical agent storage portion such that axial movement of said movable member relative thereto in a first direction causes said medical agent housed within said medical agent storage portion to be delivered through the passage to the cutting surface.

10. The assembly of claim 9, 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.

11. The assembly of claim 9, wherein the housing is fixedly connected to a portion of the surgical instrument.

12. The assembly of claim 9, wherein the agent cartridge includes a dispensing port in fluid communication with the medical agent storage portion, and wherein the passage is configured such that it remains in fluid communication with the dispensing port as the member is moved relative to the housing.

13. The assembly of claim 9, wherein the agent cartridge is directly connected to the housing.

14. The assembly of claim 9, further comprising a staple cartridge connected to the housing.

15. The assembly of claim 9, further comprising a medical agent driver extending from the movable member, wherein the driver is configured to engage the agent cartridge and dispense the medical agent from the medical agent storage portion to the passage as the cutting member is moved relative to the housing.
