Abstract

A surgical instrument including a handle assembly, an elongated body portion, a head portion and an elongated channel. The elongated body portion extends distally from the handle assembly. The head portion is disposed adjacent a distal end of the elongated body portion and includes an anvil assembly and a shell assembly. The elongated channel includes a proximal opening and a distal opening. The proximal opening is disposed distally of a proximalmost end of the handle assembly and proximally of the shell assembly. The distal opening is disposed on the shell assembly.

First claim

What is claimed:

1. A surgical stapling instrument, comprising:
a handle assembly;
an elongate body portion extending distally from the handle assembly;
a head portion disposed adjacent a distal end of the elongate body portion, the head portion including an anvil assembly and a shell assembly, the anvil assembly movable relative to the shell assembly; and
an elongate channel configured to receive a surgical object therethrough, the elongate channel including a proximal opening and a distal opening, the elongate channel extending at least a length of the elongate body portion, the proximal opening disposed proximal of the shell assembly and proximal of a longitudinal midpoint of the elongate body portion, the distal opening disposed on the shell assembly.

2. The surgical stapling instrument of claim 1 , wherein the proximal opening of the elongate channel is distal of a proximal-most end of the handle assembly.

3. The surgical stapling instrument of claim 1 , wherein the proximal opening of the elongate channel is adjacent a proximal portion of the elongate body portion.

4. The surgical stapling instrument of claim 1 , wherein the distal opening is displaced from an axial center of the shell assembly.

5. The surgical stapling instrument of claim 4 , wherein the distal opening of the elongate channel is displaced in a range from about 0.20 inches to about 0.30 inches from the axial center of the shell assembly.

6. The surgical stapling instrument of claim 1 , wherein the distal opening of the elongate channel is disposed at a distal surface of the shell assembly.

7. The surgical stapling instrument of claim 1 , wherein the proximal opening of the elongate channel is distal of the handle assembly.

8. The surgical stapling instrument of claim 1 , wherein the elongate body portion has a uniform diameter.

9. The surgical stapling instrument of claim 1 , wherein a diameter of the elongate channel is in a range from about 0.115 inches to about 0.135 inches.

10. The surgical stapling instrument of claim 1 , wherein the elongate body portion includes a curved portion.

11. The surgical stapling instrument of claim 1 , wherein the proximal and distal openings of the elongate channel are in fluid communication.

12. The surgical stapling instrument of claim 1 , wherein the proximal opening of the elongate channel is defined in a side wall of the elongate body portion.

13. A surgical stapling instrument, comprising:
a handle assembly;
an elongate body portion extending distally from the handle assembly, distal-most and proximal-most ends of the elongate body portion having the same diameter;
a head portion disposed adjacent a distal end of the elongate body portion and including a shell assembly and an anvil assembly movable relative to the shell assembly; and
an elongate channel including a proximal opening and a distal opening, the proximal opening disposed in a side wall of the elongate body portion, wherein the elongate channel extends at least a length of the elongate body portion such that the elongate channel provides a surgical object inserted through the elongate channel access to a surgical site.

14. The surgical stapling instrument of claim 13 , wherein the elongate body portion includes a curved portion.

15. The surgical stapling instrument of claim 13 , wherein at least a portion of the elongate channel is completely surrounded by the side wall of the elongate body portion.
