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 of the first jaw member and the second jaw member being movable with respect to the other jaw member between spaced and approximated positions, the first jaw member including an upper tissue-contacting surface and a lower shelf portion, the shelf portion including a groove defined therein;
a stop member disposed adjacent a distal portion of the first jaw member, the stop member being pivotable with respect to the first jaw member between a first position where a significant portion of the stop member is positioned external to the first jaw member, and a second position where a lower portion of the stop member is positioned at least partially within the groove of the shelf portion.

Abstract
A surgical instrument including a handle assembly, an elongated portion, an end effector, and a stop member is disclosed. 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 first jaw member includes an upper tissue-contacting surface and a lower shelf portion. The shelf portion includes a groove disposed therein. 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 where a lower portion of the stop member being positioned at least partially within the groove.

14. 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, the first jaw member including an upper tissue-contacting surface and a lower shelf portion, the shelf portion including a groove disposed therein; a stop member disposed adjacent a distal portion of the first jaw member, the stop member being pivotable 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 wherein at least a portion of the stop member is positioned within the groove, 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 (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
