Tissue stop for surgical instrument
First Claim
1. A surgical instrument for surgically joining tissue, the surgical instrument comprising:
- a handle assembly;
an elongated portion extending distally from the handle assembly and defining a longitudinal axis;
an end effector disposed adjacent a distal portion of the elongated portion, the end effector including a first jaw member and a second jaw member, at least one jaw member being movable with respect to the other jaw member between spaced and approximated positions;
a stop member disposed adjacent a distal portion of the first jaw member, the stop member being pivotable about a pivot with respect to the first jaw member between a first position, a significant portion of the stop member being positioned external to the first jaw member, and a second position capturing the tissue between the first jaw member and second jaw member, the relative movement of the jaw members toward the approximated position causing at least a portion of the stop member to move toward the first jaw member.

Abstract
A surgical including a handle assembly, an elongated portion, an end effector, and a stop member is disclosed. The elongated portion extends distally from the handle assembly. The end effector is disposed adjacent a distal portion of the elongated portion and includes a first jaw member and a second jaw member. At least one jaw member is movable with respect to the other jaw member between spaced and approximated positions. The stop member is disposed adjacent a distal portion of the first jaw member and is pivotable with respect to the first jaw member between a first position, a significant portion of the stop member being positioned external to the first jaw member, and a second position capturing the tissue between the first jaw member and second jaw member.

9. A tool assembly for use with a surgical instrument, the tool assembly comprising:
-
an end effector including a first jaw member and a second jaw member, at least one jaw member being movable with respect to the other jaw member between spaced and approximated positions; a stop member disposed adjacent a distal portion of the first jaw member, the stop member being pivotable about a pivot with respect to the first jaw member between a first position wherein at least a portion of the stop member is positioned external to the first jaw member, and a second position capturing the tissue between the first jaw member and second jaw member, wherein the relative movement of the jaw members toward the approximated position causes at least a portion of the stop member to move toward the first jaw member. - View Dependent Claims (10, 11, 12, 13)

14. A method of fastening tissue with surgical fasteners, comprising:
-
disposing the tissue between a first jaw member and a second jaw member; pivoting the first jaw member about a pivot with respect to the second jaw member to engage the tissue; and pivoting a stop member disposed between the first jaw member and the second jaw member to maintain the tissue between the first jaw member and second jaw member, the stop member being disposed at distal ends of the jaws, the relative movement of the jaw members toward the approximated position causing at least a portion of the stop member to move toward the first jaw member. - View Dependent Claims (15)
