Abstract

Surgical clip appliers are disclosed comprising a plurality of clips which are stored in a compressed state. When a stored clip is moved into the crimping chamber of the surgical clip applier, the clip can assume a configuration which is different than its stored configuration before it is crimped.

First claim

What is claimed is:

1. A surgical device for applying clips, comprising:
a shaft extending from a housing;
an end effector extending from said shaft, comprising:
a first jaw comprising a first protrusion extending therefrom; and
a second jaw comprising a second protrusion extending therefrom, wherein said first jaw and said second jaw are movable relative to each other between an open position and a closed position, and wherein said first jaw and said second jaw at least partially define a receiving chamber;

a cartridge, comprising:
a storage chamber; and
a plurality of clips removably positioned within said storage chamber, wherein each clip of said plurality of clips is in a storage configuration;

a firing drive configured to advance a clip of said plurality of clips positioned in said storage chamber onto said first protrusion and said second protrusion; and
a crimping drive configured to move said first jaw and said second jaw to said open position during a retraction stroke, wherein said clip positioned on said first protrusion and said second protrusion is transitioned from said storage configuration to a deployment configuration during said retraction stroke, wherein said deployment configuration is larger than said storage configuration, and wherein each clip of said plurality of clips is transitioned from said storage configuration to said deployment configuration prior to being advanced by said firing drive into said receiving chamber.

2. The surgical device of claim 1 , wherein said firing drive is further configured to advance said clip in said deployment configuration into said receiving chamber, wherein said crimping drive is further configured to move said first jaw and said second jaw to said closed position during a crimping stroke, and wherein said clip is configured to be crimped around patient tissue during said crimping stroke.

3. The surgical device of claim 2 , wherein said crimped clip is released from said receiving chamber when said first jaw and said second jaw are moved to said open position during another retraction stroke of said crimping drive, and wherein another clip is transitioned from said storage configuration to said deployment configuration during said another retraction stroke.

4. The surgical device of claim 2 , wherein said firing drive comprises a support portion configured to support a proximal portion of said clip during the transition of said clip from said storage configuration to said deployment configuration.

5. The surgical device of claim 1 , wherein said first jaw comprises a first cam member, wherein said second jaw comprises a second cam member, and wherein said first cam member and said second cam member interact with said crimping drive to move said first jaw and said second jaw to said open position during said retraction stroke.

6. The surgical device of claim 1 , wherein said cartridge is releasably attachable to the surgical device.

7. A surgical device for applying clips, comprising:
a shaft extending from a housing;
an end effector extending from said shaft, comprising:
a first jaw comprising a first protrusion extending therefrom; and
a second jaw comprising a second protrusion extending therefrom, wherein said first jaw and said second jaw are movable relative to each other between an open position and a closed position, and wherein said first jaw and said second jaw at least partially define a receiving chamber;

a cartridge, comprising:
a storage chamber; and
a plurality of clips removably positioned within said storage chamber, wherein each clip of said plurality of clips is in a storage configuration;

a firing drive configured to advance a clip of said plurality of clips positioned in said storage chamber onto said first protrusion and said second protrusion; and
a crimping drive configured to move said first jaw and said second jaw to said open position during a retraction stroke, wherein said clip positioned on said first protrusion and said second protrusion is transitioned from said storage configuration to a deployment configuration during said retraction stroke, wherein said deployment configuration is larger than said storage configuration, wherein said first protrusion comprises a first angled surface, wherein said second protrusion comprises a second angled surface, and wherein said first angled surface and said second angled surface allow said clip to slide past said first protrusion and said second protrusion as said clip is advanced towards said receiving chamber.

8. A surgical device for applying clips, comprising:
a shaft extending from a housing;
an end effector extending from said shaft, wherein said end effector comprises a receiving chamber;
a plurality of clips removably positioned within a clip cartridge, wherein said clip cartridge is releasably attachable to said surgical device, wherein each clip of said plurality of clips is configured to assume a plurality of states during operation of said surgical device, and wherein said plurality of states comprises:
a storage state, wherein each clip of said plurality of clips comprises a first size when in said storage state; and
a deployment state, wherein each clip of said plurality of clips comprises a second size larger than said first size when in said deployment state;

pre-form features configured to transition a clip of said plurality of clips from said storage state to said deployment state; and
a firing drive configured to advance said clip from said clip cartridge into said receiving chamber of said end effector, wherein each clip of said plurality of clips is transitioned from said storage state to said deployment state prior to being advanced by said firing drive into said receiving chamber.

9. The surgical device of claim 8 , further comprising a crimping drive configured to crimp said clip in said receiving chamber around patient tissue during a crimping stroke.

10. The surgical device of claim 9 , wherein said crimped clip is released from said receiving chamber during a retraction stroke of said crimping drive, and wherein another clip is transitioned from said storage state to said deployment state during said retraction stroke.

11. The surgical device of claim 8 , wherein said firing drive comprises a support portion configured to support a proximal portion of said clip during the transition of said clip from said storage state to said deployment state.

12. The surgical device of claim 11 , wherein said support portion is further configured to support said proximal portion of said clip when said clip is advanced into said receiving chamber.

13. The surgical device of claim 8 , wherein said end effector further comprises a first jaw and a second jaw which at least partially define said receiving chamber, wherein said first jaw and said second jaw are movable relative to each other between an open position and a closed position, and wherein said pre-form features comprise a first protrusion on said first jaw and a second protrusion on said second jaw.

14. A surgical device for applying clips, comprising:
a shaft extending from a housing;
an end effector extending from said shaft, wherein said end effector comprises a receiving chamber;
a plurality of clips removably positioned within a clip cartridge, wherein said clip cartridge is releasably attachable to said surgical device, wherein each clip of said plurality of clips is configured to assume a plurality of states during operation of said surgical device, and wherein said plurality of states comprises:
a storage state, wherein each clip of said plurality of clips comprises a first size when in said storage st
