making it suitable for connection of bones or serving as a framework of stem cells in an actual operation it is possible to solely form the internal layer 10 through braiding the filaments and the internal layer 10 is thus made in the form of a bone connection material further an arrangement of the covering layer 20 may be additionally included so as to make the application of the bone connection material wide the covering layer 20 is made of a thermoplastic resin a thermosetting resin biocompatible polymer or a biodegradable resin and matrix collagen hydroxylapatite ha or may further include other additives 21 as shown in fig8 and fig8 a such as collagen hydroxylapatite ha or tricalcium phosphate tcp ha is a major constituent of human bone tissues and once implanted in human bodies may release calcium and phosphorus that may be absorbed by body tissues to grow new tissues generally the human body will itself generate ha or related or similar elements for proceeding with reconstruction of bones but the time it may take is dependent on the individual body the covering layer provided by the present invention is provided to contain such bone reconstruction materials so as to be used for body reconstruction and to provide an effect of accelerated restoration further the filaments 11 can be bioactive glass fibers ceramic fiber materials bioactive materials or bioinert glass fiber materials which can be used and arranged corresponding to the needs of the actual situations further the internal layer 10 can be made in the form of a bone screw as shown in fig1 or bone plates for connection shown.
