Tissue stop for surgical instrument
A surgical instrument for surgically joining a tissue includes a handle assembly, an elongate portion extending distally from the handle assembly, a pair of opposed jaw members, and a tissue stop. 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.
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.
2. The surgical instrument of claim 1 , wherein the plane is parallel with a longitudinal axis defined by the elongate portion.
3. 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.
4. 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.
5. The surgical instrument of claim 4 , wherein the tissue stop includes a pair of lateral walls.
6. The surgical instrument of claim 5 , wherein the stopping portion is disposed on a proximal edge of each of the pair of lateral walls.
7. 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.
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.
9. The jaw member of claim 8 , wherein the plane extends along a length of the curved body.
10. The jaw member of claim 8 , wherein the tissue stop includes a stopping portion disposable on the tissue-contacting surface of the curved body.
11. The jaw member of claim 10 , wherein the tissue stop includes a pair of lateral walls.
12. The jaw member of claim 11 , wherein the stopping portion is disposed on a proximal edge of each of the pair of lateral walls.
13. 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.
14. The jaw member of claim 8 , wherein the tissue stop includes a proximal portion pivotably engaged with the curved body.
15. The jaw member of claim 8 , wherein the tissue stop is slidably coupled to an end of the curved body.
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.
17. The jaw member of claim 16 , wherein the tissue stop includes a stopping portion disposable on the tissue-contacting surface of the curved body.
18. The jaw member of claim 16 , wherein the tissue stop includes a proximal portion pivotably engaged with the curved body.
19. The jaw member of claim 16 , wherein the tissue stop is slidably coupled to an end of the curved body.
