Abstract

A circular stapler for side to end, side to side or end to side anastomosis includes an actuating head portion attached to an elongated tubular body with a handle on the opposed end of the body from the head. The head includes an anvil and associated stapling mechanism, wherein the anvil and the associated stapling mechanism are positioned perpendicular to a longitudinal axis of the head. The anvil is releasably attached to the head and may be attached to the head through an anvil applicator. The anvil may include an extendable stem.

Claims

1. An applicator system for an anastomotic surgical stapler, said system comprising:

an anvil for an anastomotic surgical stapler; and

an applicator receiving and transporting said anvil, said applicator comprising an anvil receiving sleeve and a reciprocating movable plunger mounted within said anvil receiving sleeve, wherein said anvil is adapted to be supported on said plunger and movement of said plunger is adapted to move said anvil into engagement with the head of the surgical stapler.

2. An anvil applicator system for manually manipulating a removable anvil of an anastomotic surgical stapler having an actuating head portion including an associated stapling mechanism, system comprising:

a removable anvil of an anastomotic stapler; and

an anvil applicator fro manipulating said anvil, wherein the removable anvil is removably supported by said anvil applicator for connection to the head portion of the anastomotic surgical stapler, in situ, said anvil applicator having an elongated body having a first end gripped and manipulated by the user and a distal end supporting anvil, wherein said anvil applicator is removed from said anvil after said anvil is attached to the head portion of the surgical stapler.

3. The anvil applicator system of claim 2, wherein said first end of said anvil applicator forms a handle which includes a grip for receiving the user'"'"'s fingers.

4. The anvil applicator system of claim 3, wherein said distal end of said anvil applicator is formed as the end of a plunger.

5. The anvil applicator system of claim 4, further including a tube receiving said distal end of said anvil applicator.

6. The anvil applicator system of claim 5, wherein said end of said plunger is shaped to conform to said anvil.

7. The anvil applicator system of claim 6, wherein said anvil includes a telescoping stem.

8. The anvil applicator system of claim 2, wherein said anvil includes a telescoping stem.

9. The anvil applicator system of claim 2, wherein said anvil includes an extended length stem.

10. The anvil applicator system of claim 2, wherein said anvil applicator further includes an anvil receiving sleeve and said distal end is formed as a reciprocating movable plunger mounted within said anvil receiving sleeve.
