Surgical suture material with barbs cut into it in the undrawn state

Abstract

A surgical suture material includes a drawn elongate main body and barbs adapted to anchor in human and/or animal tissues, wherein the barbs are partially in drawn form.

1 . A surgical suture material comprising a drawn elongate main body and barbs adapted to anchor in human and/or animal tissues, wherein the barbs are partially in drawn form. 
     
     
         2 . The drawn surgical suture material according to  claim 1 , wherein the main body has cut surfaces extending in a longitudinal direction of the suture material. 
     
     
         3 . The drawn surgical suture material according to  claim 2 , wherein the cut surfaces are substantially planar. 
     
     
         4 . The drawn surgical suture material according to  claim 1 , wherein the main body has cut surfaces extending in a longitudinal direction of the suture material and are longer than cut surfaces of undersides of the barbs. 
     
     
         5 . The drawn surgical suture material according to  claim 1 , wherein the main body has cut surfaces extending in a longitudinal direction of the suture material and whose length corresponds to at least 1.1 times the length of cut surfaces of undersides of the barbs. 
     
     
         6 . The drawn surgical suture material according to  claim 1 , wherein the barbs have an apex angle α of 10 to 70 degrees. 
     
     
         7 . The drawn surgical suture material according to  claim 1 , wherein the barbs protrude from the main body. 
     
     
         8 . The drawn surgical suture material according to  claim 1 , wherein the barbs have a righting angle β of 35 to 75 degrees measured from a cut surface of an underside of the barb to a cut surface of the main body. 
     
     
         9 . The drawn surgical suture material according to  claim 1 , wherein the suture material has a cut surface angle γ of 160 to 178 degrees measured from a cut surface of the main body to an uncut outer surface of the main body. 
     
     
         10 . The drawn surgical suture material according to  claim 1 , wherein the barbs have a strengthened back. 
     
     
         11 . The drawn surgical suture material according to  claim 1 , wherein the barbs have a back with a material strengthening in the form of a material accumulation or material thickening. 
     
     
         12 . The drawn surgical suture material according to  claim 1 , wherein the suture material has an elongation at break of 20 to 100%. 
     
     
         13 . The drawn surgical suture material according to  claim 1 , wherein the barbs spaced apart in a longitudinal direction have a mutual spacing of 0.5 to 5 mm measured from barb tip to barb tip. 
     
     
         14 . The drawn surgical suture material according to  claim 1 , wherein the main body in areas of cut surfaces extending in a longitudinal direction of the suture material has a diameter of 0.2 to 2.0 mm. 
     
     
         15 . The drawn surgical suture material according to  claim 1 , wherein the suture material has a ratio of barb height to diameter of the suture material of 1.3 to 0.5. 
     
     
         16 . The drawn surgical suture material according to  claim 1 , wherein the suture material has a ratio of barb cut length to diameter of the suture material of 2 to 0.4. 
     
     
         17 . The drawn surgical suture material according to  claim 1 , wherein the suture material has a ratio of barb spacing to diameter of the suture material of 2 to 25. 
     
     
         18 . The drawn surgical suture material according to  claim 1 , wherein the suture material has a monofilament configuration. 
     
     
         19 . A surgical kit comprising at least one surgical needle and a suture material according to  claim 1 .
