Anchor Element For Knotless Fixing Of Tissue To A Bone

Abstract

An anchor element serves for knotless fixing of a tissue to a bone by means of at least one suture threaded through said anchor element. A body of that anchor element has an outer surface with projections. A transverse bore is arranged in a distal end section of said body for receiving a threading passing therethrough. A clamp element serves for clamping the suture threaded transversely through the bore. The clamping element has a portion arranged within the body and is movably within the body towards that transverse bore.

1 . An anchor element for knotless fixing of a tissue to a bone by means of at: least one suture threaded through said anchor element, comprising 
 a body having an outer face    projections protecting from said outer face for preventing removal of said anchor element when inserted in the bone,    a transverse bore arranged in a distal end section of said body, said transverse bore extending through said body, and serving for threading said at least one suture transversely through said body,    a clamp element for clamping said suture threaded transversely through said bore, wherein    said clamping element having a portion arranged within said body,    said clamping element being arranged movably within said body and being movably towards said transverse bore for clamping said suture in said transverse bore.    
   
   
       2 . The anchor element of  claim 1 , wherein said body has an axially extending inner bore for receiving said clamping element.  
   
   
       3 . The anchor element of  claim 2 , wherein said inner bore opens into said transverse bore.  
   
   
       4 . The anchor element of  claim 1 , wherein a distal end of said clamp element is rounded.  
   
   
       5 . The anchor element of  claim 4 , wherein opposite to said rounded distal end of said clamping element, a gentle hollow is provided in said transverse bore, said gentle hollow approximately corresponds to said rounded distal end.  
   
   
       6 . The anchor element of  claim 1 , wherein said portion of said clamping element arranged inside said body is designed as a pin.  
   
   
       7 . The anchor element of  claim 6 , wherein said pin is designed as a headless screw.  
   
   
       8 . The anchor element of  claim 1 , wherein said clamp element is received completely within said body.  
   
   
       9 . The anchor element of  claim 1 , wherein said clamp element is designed as a conical element.  
   
   
       10 . The anchor element of  claim 1 , wherein said clamp element has an assembly feature onto which a tool of a driver device for driving said anchor element can be attached.
