Fluidtight puncturing and occlusion device for anatomical structure

Abstract

A surgical staple for a surgical stapling device fitted with a substantially flat back that can deform between a closed position and an open penetration position of the staple, and two spaced-apart pin rows. The back comprises two parts that are hinged with respect to each other. The two pin rows are affixed by the base of the pins to these two parts, substantially lying along axes perpendicular to a plane of each of the two parts. In the closed position of the back a free end of the pins of the two rows converge, but when the back is in the open penetration position, the axes of the pins of the two rows tend to align parallel to each other so as to offer minimal resistance to penetration into tissues and the parts of the back bearing the bases of the pins are separated by a gap larger than in the closed position. The staple is particularly designed to be used with a combined device for plugging and fluidtight puncturing of a wall of a hollow organ.

         19 . A surgical staple for a surgical stapling device comprising a substantially flat back that can deform between a closed position of the staple and an open penetration position of the staple, and at least two spaced-apart pin rows wherein:
 the back comprises two parts that are hinged with respect to each other;   the at least two pin rows are affixed by the base of the pins to these two parts, substantially lying along axes perpendicular to a plane of each of the two parts;   in the closed position of the back a free end of the pins of the two rows converge;   when the back is in the open penetration position, the axes of the pins of the two rows tend to align parallel to each other so as to offer minimal resistance to penetration into tissues and the parts of the back bearing the base of the pins are separated by a gap larger than in the closed position;   said staple being provided with a central opening and with gripping points for keeping the staple in one position,   the back of the staple not protruding from the wall of the hollow organ when the staple is in place.   
     
     
         20 . A surgical staple according to  claim 19  wherein the back is elastically deformable. 
     
     
         21 . A surgical staple according to  claim 20 , wherein the two parts are joined together by springy joins. 
     
     
         22 . A surgical staple according to  claim 19  wherein the back is plastically deformable.
