Abstract

A surgical device for clipping tissue can include a replaceable cartridge comprising a stack of clips contained therein and a firing drive configured to reciprocatingly eject, or deploy, the clips from the cartridge. After the clips have been deployed from the cartridge, a blocking member can be positioned to impede or block the firing drive. In at least one embodiment, the cartridge can include a biasing member configured to bias the blocking member into a firing chamber defined in the cartridge and/or surgical device. The surgical device can also include a crimping drive configured to deform a clip after it has been ejected from the cartridge. The blocking member can also be configured to impede or block the crimping drive after all of the clips from the cartridge have been used.

Claims

1. A clip applier for clipping tissue, comprising:

a shaft;

a firing chamber;

an end effector extending from said shaft, wherein said end effector comprises a crimping chamber;

a magazine assembly, comprising;

a housing;

a storage chamber defined in said housing;

a plurality of clips removably positioned within said storage chamber; and

a biasing member configured to sequentially bias said clips from said storage chamber into said firing chamber;

a reciprocating firing drive configured to advance a clip positioned in said firing chamber into said crimping chamber; and

a lockout plate positioned intermediate said biasing member and said plurality of clips, wherein said biasing member is configured to bias said lockout plate into said firing chamber after all of the plurality of said clips have been advanced into said crimping chamber, and wherein said lockout plate is configured to block said firing drive.

2. The clip applier of claim 1, wherein said shaft further comprises:

a proximal portion;

a distal portion, wherein said firing chamber is defined in said distal portion; and

an articulation joint rotatably connecting said proximal portion and said distal portion of said shaft.

3. The clip applier of claim 1, wherein said housing further comprises a proximal opening configured to receive said firing drive.

4. The clip applier of claim 1, wherein said lockout plate comprises a plurality of guides, and wherein said housing comprises a plurality of co-operating guides configured to co-operate with said guides to define the movement of said lockout plate along a predetermined path.

5. The clip applier of claim 1, wherein said housing comprises a shelf and a discharge opening, wherein said biasing member is configured to bias a said clip against said shelf, and wherein said shelf is aligned with said discharge opening.

6. The clip applier of claim 1, further comprising a first jaw and a second jaw, wherein said crimping chamber is defined between said first jaw and said second jaw, and wherein said first jaw is movable toward said second jaw to deform a clip positioned in said crimping chamber.

7. The clip applier of claim 6, further comprising a crimping drive configured to move said first jaw toward said second jaw, wherein said crimping drive is configured to be actuated in sequence with said firing drive.

8. The clip applier of claim 1, wherein said firing member is configured to enter into said housing along a firing axis, wherein said biasing member is configured to bias a said clip into said firing chamber along a supply axis, and wherein said supply axis is transverse to said firing axis.

9. The clip applier of claim 8, wherein said supply axis is perpendicular to said firing axis.

10. The clip applier of claim 1, further comprising a cartridge lock configured to releasably hold said magazine assembly in a magazine aperture defined in said shaft.

11. A surgical device for applying clips, comprising:

a shaft;

an end effector comprising a receiver;

a cartridge, comprising;

a housing;

a storage chamber defined in said housing;

a stack of clips removably positioned within said storage chamber;

a firing platform; and

a biasing member configured to sequentially bias said clips from said storage chamber onto said firing platform;

a reciprocating firing drive configured to advance a said clip positioned on said firing platform into said receiver; and

a lockout member positioned intermediate said biasing member and said stack of clips, wherein said biasing member is configured to bias said lockout member against said firing platform after all of said clips have been advanced into said receiver, and wherein said lockout member is configured to block said firing drive.

12. The surgical device of claim 11, wherein said shaft comprises:

a proximal portion;

a distal portion, wherein said firing platform is defined in said distal portion; and

an articulation joint rotatably connecting said proximal portion and said distal portion of said shaft.

13. The surgical device of claim 11, wherein said housing further comprises a proximal opening configured to receive said firing drive, and wherein said proximal opening is aligned with said firing platform.

14. The surgical device of claim 11, wherein said lockout member comprises a plurality of guides, and wherein said housing comprises a plurality of co-operating guides configured to co-operate with said guides to define the movement of said lockout member along a predetermined path.

15. The surgical device of claim 11, further comprising a first jaw and a second jaw, wherein said receiver is defined between said first jaw and said second jaw, and wherein said first jaw is movable toward said second jaw to deform a clip positioned in said receiver.

16. The surgical device of claim 15, further comprising a crimping drive configured to move said first jaw toward said second jaw, wherein said crimping drive is configured to be actuated in sequence with said firing drive.

17. The surgical device of claim 11, wherein said firing member is configured to enter into said housing along a firing axis, wherein said biasing member is configured to bias a said clip onto said firing platform along a supply axis, and wherein said supply axis is transverse to said firing axis.

18. The surgical device of claim 17, wherein said supply axis is perpendicular to said firing axis.

19. The surgical device of claim 11, further comprising a cartridge lock configured to releasably hold said cartridge in a cartridge aperture defined in said shaft.

20. A surgical device for clipping tissue, comprising:

a shaft;

an end effector comprising a receiver;

a cartridge, comprising;

a housing;

a storage chamber defined in said housing;

a stack of clips removably positioned within said storage chamber;

a firing chamber; and

a biasing member configured to sequentially bias said clips from said storage chamber into said firing chamber;

a reciprocating firing drive configured to advance a said clip positioned in said firing chamber into said receiver during a firing stroke; and

blocking means for inhibiting said firing drive from completing a firing stroke after all of said clips have been advanced into said receiver.
