The tissue stop is mechanically engaged with a first jaw member and is configured to retain the tissue between the jaw members. The tissue stop is 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 between the tissue-contacting surface of the first jaw member and a lower surface of the first jaw member. A portion of the tissue stop is made of stamped metal section and a portion of the tissue stop is made of an overmolded plastic section. ## Claims ### Claim 1 A surgical instrument for surgically joining tissue, comprising: a handle assembly; an elongate portion extending from the handle assembly; a pair of opposed jaw members operatively coupled to the elongate portion and extending therefrom; and a tissue stop mechanically coupled to one of the pair of opposed jaw members such that a distal portion of the tissue stop is movable relative to the one of the pair of opposed jaw members and in a direction parallel with a plane defined by a tissue contacting surface of the one of the pair of opposed jaw members. ### Claim 2 (depends on 1) The surgical instrument of claim 1, wherein the plane is parallel with a longitudinal axis defined by the elongate portion. ### Claim 3 (depends on 1) The surgical instrument of claim 1, wherein the tissue stop includes a first portion made of stamped metal and a second portion made of plastic overmolded onto the first portion. ### Claim 4 (depends on 1) The surgical instrument of claim 1, wherein the tissue stop includes a stopping portion disposable between the tissue-contacting surface of the one of the pair of opposed jaw members and a tissue-contacting surface of another of the pair of opposed jaw members. ### Claim 5 (depends on 4) The surgical instrument of claim 4, wherein the tissue stop includes a pair of lateral walls. ### Claim 6 (depends on 5) The surgical instrument of claim 5, wherein the stopping portion is disposed on a proximal edge of each of the pair of lateral walls. ### Claim 7 (depends on 1) The surgical instrument according to claim 1, wherein the tissue stop is mechanically coupled to an end of the one of the pair of opposed jaw members. ### Claim 8 A jaw member of a surgical end effector, the jaw member comprising: a curved body having a tissue-contacting surface, the tissue-contacting surface defining a plane; and a tissue stop slidably coupled to the curved body such that a distal portion of the tissue stop is slidable in a direction parallel with the plane of the tissue-contacting surface of the curved body. ### Claim 9 (depends on 8) The jaw member of claim 8, wherein the plane extends along a length of the curved body. ### Claim 10 (depends on 8) The jaw member of claim 8, wherein the tissue stop includes a stopping portion disposable on the tissue-contacting surface of the curved body. ### Claim 11 (depends on 10) The jaw member of claim 10, wherein the tissue stop includes a pair of lateral walls. ### Claim 12 (depends on 11) The jaw member of claim 11, wherein the stopping portion is disposed on a proximal edge of each of the pair of lateral walls. ### Claim 13 (depends on 8) The jaw member of claim 8, wherein the tissue stop includes a first portion made of stamped metal and a second portion made of plastic overmolded onto the first portion. ### Claim 14 (depends on 8) The jaw member of claim 8, wherein the tissue stop includes a proximal portion pivotably engaged with the curved body. ### Claim 15 (depends on 8) The jaw member of claim 8, wherein the tissue stop is slidably coupled to an end of the curved body. ### Claim 16 A jaw member of a surgical end effector, the jaw member comprising: a curved body having a tissue-contacting surface; and a tissue stop slidably coupled to the curved body such that a portion of the tissue stop is slidable relative to the tissue-contacting surface of the curved body and along a straight axis, wherein the tissue stop includes a first portion made of stamped metal and a second portion made of plastic overmolded onto the first portion. ### Claim 17 (depends on 16) The jaw member of claim 16, wherein the tissue stop includes a stopping portion disposable on the tissue-contacting surface of the curved body. ### Claim 18 (depends on 16) The jaw member of claim 16, wherein the tissue stop includes a proximal portion pivotably engaged with the curved body. ### Claim 19 (depends on 16) The jaw member of claim 16, wherein the tissue stop is slidably coupled to an end of the curved body.
