Medical chain net

Abstract

A medical product for use during the treatment of a bone defect, having a plurality of individual elements that are connected to one another such that individual elements adjacent to one another engage in one another/are chained to one another. The individual elements of the chain net are subdivided into main elements and connection elements that are designed differently from the main elements. The main elements and the connection elements form, when chained to one another, a grid structure that is flat in the x-y plane.

         8 . The medical product according to  claim 7 , wherein the connection link elements are each formed as an eyelet-shaped hexagon. 
     
     
         9 . The medical product according to  claim 1 , wherein the main link elements and the connection link elements have a self-contained shape. 
     
     
         10 . The medical product according to  claim 1 , wherein the connection link elements comprise rings having a common orientation and conforming to a common first plane. 
     
     
         11 . The medical product according to  claim 10 , wherein the common first plane extends in the x-direction and the y-direction. 
     
     
         12 . The medical product according to  claim 11 , wherein each main link element is formed as a framework comprising a first polygon and a second polygon parallel to and offset from the first polygon. 
     
     
         13 . The medical product according to  claim 12 , wherein the first polygons of the main link elements conform to a common second plane, and the second polygons of the main link elements conform to a common third plane. 
     
     
         14 . The medical product according to  claim 12 , wherein the common second plane and the common third plane extend in the x-direction and the y-direction. 
     
     
         15 . The medical product according to  claim 14 , wherein the common first plane extends between the common second plane and the common third plane. 
     
     
         16 . A medical product for use in treating a bone defect, the medical product comprising a plurality of individual link elements which are connected to each other in such a way that adjacent individual link elements interlock/are linked to each other, the individual link elements being subdivided into main link elements and connection link elements, the main link elements and the connection link elements forming a planar grid structure that extends in an x-direction, a y-direction and a z-direction, the planar grid structure being planar in an x-y plane in an interlinked state, the x-y plane extending in the x-direction and the y-direction, wherein the main link elements have a first thickness in the z-direction and the connection link elements have a second thickness in the z-direction that is less than the first thickness, the connection link elements comprising rings having a common orientation and conforming to a common first plane.
