Abstract

A disposable end effector for use with a surgical fastening instrument is disclosed. The disposable end effector comprises a proximal end configured to be attached to a shaft of the surgical fastening instrument, a distal end, a first jaw, a second jaw, and a firing member. One of the first jaw and the second jaw is movable relative to the other one of the first jaw and the second jaw to transition the disposable end effector between an open configuration and a closed configuration. The firing member transitions the disposable end effector to the closed configuration. The firing member comprises a first flange configured to engage the first jaw, a second flange configured to engage the second jaw, and two engagement surfaces configured to engage the first jaw. The first flange and the second flange are comprised of a metal. Resilient material is inserted on the two engagement surfaces.

Claims

1. A disposable end effector for use with a surgical fastening instrument, said disposable end effector comprising:

a proximal end configured to be attached to a shaft of the surgical fastening instrument;

a distal end opposite said proximal end;

a first jaw extending toward said distal end;

a second jaw extending toward said distal end, wherein said second jaw is pivotably coupled to said first jaw, wherein one of said first jaw and said second jaw is movable relative to the other one of said first jaw and said second jaw to transition said disposable end effector between an open configuration and a closed configuration; and

a firing member movable toward said distal end to transition said disposable end effector to said closed configuration, said firing member comprising;

a first flange configured to engage said first jaw;

a second flange configured to engage said second jaw, wherein said first flange and said second flange are comprised of a metal; and

two engagement surfaces of said firing member configured to engage said first jaw, wherein resilient material is inserted on said two engagement surfaces.

2. The disposable end effector of claim 1, further comprising:

a plurality of fastener cavities; and

a plurality of fasteners, wherein said fasteners are removably positioned in said fastener cavities.

3. The disposable end effector of claim 2, wherein said firing member comprises a knife edge.

4. A disposable end effector for use with a surgical fastening instrument, said disposable end effector comprising:

a proximal end configured to be attached to a shaft of the surgical fastening instrument;

a distal end opposite said proximal end;

a first jaw extending toward said distal end;

a second jaw extending toward said distal end, wherein said second jaw is pivotably coupled to said first jaw, wherein one of said first jaw and said second jaw is movable relative to the other one of said first jaw and said second jaw to transition said disposable end effector between an open configuration and a closed configuration; and

a firing member movable toward said distal end to transition said disposable end effector to said closed configuration, said firing member comprising;

a first flange defining a first engagement surface, wherein said first flange is comprised of a metal and a resilient material inserted on said metal;

a second flange defining a second engagement surface, wherein said second flange is comprised of a metal and a resilient material inserted on said metal; and

wherein said firing member is configured to engage said first jaw and said second jaw to transition said disposable end effector to said closed configuration.

5. The disposable end effector of claim 4, further comprising:

a plurality of fastener cavities; and

a plurality of fasteners, wherein said fasteners are removably positioned in said fastener cavities.

6. The disposable end effector of claim 5, wherein said firing member comprises a cutting edge.

7. A disposable end effector for use with a surgical fastening instrument, said disposable end effector comprising:

a proximal end configured to be attached to a shaft of the surgical fastening instrument;

a distal end;

a first jaw;

a second jaw pivotably coupled to said first jaw, wherein one of said first jaw and said second jaw is movable relative to the other one of said first jaw and said second jaw to transition said disposable end effector between an open configuration and a closed configuration; and

a firing member movable toward said distal end to transition said disposable end effector to said closed configuration, said firing member comprising;

a body;

a first flange extending from said body in a first direction, wherein said first flange comprises a first engagement surface configured to engage said first jaw;

a second flange extending from said body in a second direction opposite said first direction, wherein said second flange comprises a second engagement surface spaced apart from said first engagement surface, wherein said first and second flanges are comprised of a metallic material, wherein said first and second engagement surfaces are comprised of a resilient material, and wherein said firing member is configured to engage said first jaw and said second jaw to transition said disposable end effector to said closed configuration.

8. The disposable end effector of claim 7, comprising:

a plurality of fastener cavities; and

a plurality of fasteners, wherein said fasteners are removably positioned in said fastener cavities.

9. The disposable end effector of claim 8, wherein said firing member comprises a cutting edge at a distal portion of said body.
