Tissue stop for surgical instrument
First Claim
1. A surgical instrument for surgically joining a tissue, the surgical instrument comprising:
- a handle assembly including a movable handle;
an elongate portion extending distally from the handle assembly and defining a longitudinal axis;
a pair of opposed jaw members operatively coupled to the elongate portion and extending distally therefrom, the pair of opposed jaw members including a first jaw member and a second jaw member, the first jaw member defining first and second cam slots; and
a tissue stop configured to retain the tissue between the pair of opposed jaw members, the tissue stop being operatively coupled to the first jaw member, the tissue stop including a pair of cams slidably engaging the first and second cam slots, respectively, the tissue stop being movable between a first position, where a stopping portion of the tissue stop is disposed between a tissue-contacting surface of the first jaw member and a tissue-contacting surface of the second jaw member, and a second position, where the stopping portion is disposed between the tissue-contacting surface of the first jaw member and a lower surface of the first jaw member, wherein the first and second cam slots define an obtuse angle therebetween.

The pair of opposed jaw members include first and second jaw members. The tissue stop cammingly engaged with the first jaw member and is movable between a first position where at least a portion of a stopping portion of the tissue stop is disposed between a tissue-contacting surface of the first jaw member and a tissue-contacting surface of the second jaw member and a second position where the portion of the stopping portion is between the tissue-contacting surface of the first jaw member and a lower surface of the first jaw member.
