MULTI-FUNCTIONAL POWERED SURGICAL DEVICE WITH EXTERNAL DISSECTION FEATURES
A surgical end effector can comprise a first jaw member and a second jaw member. The first jaw member may define an exterior surface on a distal portion thereof. The second jaw member may define an exterior surface on a distal portion thereof. The first jaw member may be moveable relative to the second jaw member between a first position and a second position. At least one of the exterior surfaces of the first and second jaw members may include a tissue gripping portion.
1 . A surgical end effector comprising:
a first jaw member defining an exterior surface on a distal portion thereof; and
a second jaw member defining an exterior surface on a distal portion thereof, wherein the first jaw member is moveable relative to the second jaw member between a first position and a second position, and wherein at least one of the exterior surfaces of the first and second jaw members includes a tissue gripping portion.
2 . The surgical end effector of claim 1 , wherein the tissue gripping portion comprises a material having a high coefficient of friction.
3 . The surgical end effector of claim 1 , wherein the tissue gripping portion comprises a semi-rigid material.
4 . The surgical end effector of claim 1 , wherein the tissue gripping portion comprises an elastomeric material.
5 . The surgical end effector of claim 1 , wherein the tissue gripping portion comprises a gripping feature configured to be sufficiently flexible to contour without shearing upon tissue contact as the first jaw member is moved relative to the second jaw member between the first position and the second position.
6 . The surgical end effector of claim 1 , wherein the tissue gripping portion comprises a gripping pattern including a plurality of gripping features.
7 . The surgical end effector of claim 1 , wherein the tissue gripping portion includes a plurality of protrusions.
8 . The surgical end effector of claim 1 , wherein the tissue gripping portion includes a plurality of vertical protrusions extending horizontally in opposing directions.
9 . The surgical end effector of claim 1 , wherein the tissue gripping portion includes a plurality of vertical protrusions extending horizontally in parallel rows.
10 . The surgical end effector of claim 1 , wherein the tissue gripping portion includes a first plurality of parallel protrusions, and a second plurality of parallel protrusions, wherein the first plurality is in a slanted arrangement with the second plurality.
11 . The surgical end effector of claim 1 , wherein the tissue gripping portion comprises a plurality of gripping features arranged in a herringbone pattern.
12 . A surgical tool comprising:
a surgical end effector comprising:
a first jaw member defining an exterior surface on a distal portion thereof; and
a second jaw member defining an exterior surface on a distal portion thereof, wherein the first jaw member is moveable relative to the second jaw member between a first position and a second position, and wherein at least one of the exterior surfaces of the first and second jaw members includes a tissue gripping portion;
a handle assembly proximal to said surgical end effector; and
a drive shaft extending between said surgical end effector and said handle assembly, the drive shaft configured to move the first jaw relative to the second jaw between the first position and the second position in response to actuation motions in the handle.
13 . The surgical end effector of claim 12 , wherein the tissue gripping portion comprises a material having a high coefficient of friction.
14 . The surgical end effector of claim 13 , wherein the tissue gripping portion comprises an elastomeric material.
15 . The surgical end effector of claim 13 , wherein the tissue gripping portion comprises a gripping feature configured to be sufficiently flexible to contour without shearing upon tissue contact as the first jaw member is moved relative to the second jaw member between the first position and the second position.
16 . The surgical end effector of claim 13 , wherein the tissue gripping portion comprises a plurality of gripping features arranged in a herringbone pattern.
17 . A surgical tool comprising:
an actuation system for selectively generating a plurality of control motions;
a surgical end effector operably coupled to said actuation system, said surgical end effector comprising:
a first jaw member defining an exterior surface on a distal portion thereof; and
a second jaw member defining an exterior surface on a distal portion thereof, wherein the first jaw member is movably supported relative to the second jaw member between an open position and a closed position in response to closure motions generated by said actuation system, wherein at least one of the exterior surfaces of the first and second jaw members includes a tissue adhering portion; and
a shaft assembly for transmitting said plurality of control motions to the surgical end effector.
18 . The surgical stapling tool of claim 17 , wherein the tissue adhering portion comprises an elastomeric material.
19 . The surgical end effector of claim 17 , wherein the tissue adhering portion comprises a gripping feature configured to be sufficiently flexible to contour without shearing upon tissue contact as the first jaw member is moved relative to the second jaw member between the first position and the second position.
20 . The surgical end effector of claim 17 , wherein the tissue adhering portion comprises a plurality of gripping features arranged in a herringbone pattern.
