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.
Claims28
A surgical stapling instrument, comprising:
- a handle assembly having a proximal-most end, the handle assembly being configured to be held during typical use of the surgical stapling instrument, the handle assembly having a tapered portion progressively tapering in a distal direction, the tapered portion terminating at a distal terminal end;
- an elongated body portion defining a longitudinal axis and extending distally from the handle assembly, the elongated body portion including side walls and a non-tapered diameter portion extending distally from the terminal end of the handle assembly, the elongated body portion having a constant diameter along its entire length;
- a head portion disposed adjacent a distal end of the elongated body portion and including an anvil assembly and a shell assembly;
- and
- an elongated channel including a proximal opening and a distal opening, the proximal opening being disposed in the side wall of the non-tapered diameter portion of the elongated body portion, distally of a terminal end of the handle assembly and proximally of a longitudinal midpoint of the elongated body portion, and the distal opening being disposed on the shell assembly, wherein substantially a majority of the elongated channel is completely surrounded by the side walls of the elongated body portion.

A surgical stapling instrument, comprising:
- a handle assembly;
- an elongated body portion defining a longitudinal axis and extending distally from the handle assembly, the elongated body portion having a constant diameter along its entire length;
- a head portion disposed adjacent a distal end of the elongated body portion and including an anvil assembly and a shell assembly;
- and
- an elongated channel including a proximal-most opening and a distal opening, the proximal-most opening being disposed in a side wall of the elongated body portion distally of the handle assembly and proximally of a longitudinal midpoint of the elongated body portion, the proximal-most opening being formed on a circumferential wall of the elongated body portion, the circumferential wall forming a radially outer-most boundary of the elongated body portion, the proximal-most opening is the initial opening to provide access by another instrument to the surgical stapling instrument, and the distal opening being disposed on the shell assembly, wherein a distal-most edge of the proximal opening being disposed proximally of the longitudinal midpoint of the elongated body portion.

A surgical instrument, comprising:
- a handle assembly;
- an endoscopic portion defining a longitudinal axis and disposed distally of the handle assembly, the endoscopic portion including a side wall, the endoscopic portion having a constant diameter along its entire length;
- a head portion disposed adjacent a distal end of the endoscopic portion and including an anvil assembly and a shell assembly;
- and
- an elongated channel including a proximal opening and a distal opening, the proximal opening being disposed in the side wall of a portion of the endoscopic portion having a constant diameter and proximally of a longitudinal midpoint of the endoscopic portion, and the distal opening being disposed on the shell assembly, a majority of the elongated channel between a proximal-most portion of the proximal opening and the distal opening being completely surrounded by the side walls of the endoscopic portion.
