Abstract

An end effector for stapling and cutting tissue is disclosed. The end effector comprises a housing, staples removably stored in the housing, a cutting portion configured to cut the tissue, and a collapsible ring. The ring is deployable between a first configuration and a second configuration to engage the tissue. The end effector further comprises an actuator configured to deploy the ring between the first configuration and the second configuration and pull the tissue within the cutting portion after the ring has been engaged with the tissue.

First claim

What is claimed is:

1. A stapling instrument for stapling and cutting tissue, comprising:
a housing;
staples removably stored in said housing;
a blade comprising a perimeter;
a tissue tacking collar, wherein said tissue tacking collar is deployable between a first configuration and a second configuration to engage said tissue;
a cinching mechanism configured to deploy said tissue tacking collar between said first configuration and said second configuration; and
an actuator system configured to pull the tissue within said blade perimeter after said tissue tacking collar has been engaged with the tissue.

2. The stapling instrument of claim 1 , wherein said housing comprises a circular cartridge body, and wherein said staples are deployable in a circular row.

3. The stapling instrument of claim 1 , wherein said tissue tacking collar comprises deployable tacks.

4. An end effector for stapling and cutting tissue, comprising:
a housing;
staples removably stored in said housing;
a blade comprising an inner perimeter, wherein said blade is configured to incise the tissue;
a tissue collar, wherein said tissue collar is deployable between a first configuration and a second configuration;
a cinching mechanism configured to deploy said tissue collar between said first configuration and said second configuration; and
an actuator configured to pull the tissue within said inner perimeter after said tissue tacking collar has been engaged with the tissue.

5. The end effector of claim 4 , wherein said housing comprises a circular cartridge body, and wherein said staples are deployable in a circular row.

6. The end effector of claim 4 , wherein said tissue collar comprises deployable tacks.

7. An end effector for stapling and cutting tissue, comprising:
a housing;
staples removably stored in said housing;
a cutting portion configured to cut the tissue;
a collapsible ring, wherein said ring is deployable between a first configuration and a second configuration to engage the tissue; and
an actuator configured to deploy said ring between said first configuration and said second configuration and pull the tissue within said cutting portion after said ring has been engaged with the tissue.

8. The end effector of claim 7 , wherein said housing comprises a circular cartridge body, and wherein said staples are deployable in a circular row.

9. The end effector of claim 7 , wherein said ring comprises deployable tacks.
