The utility model discloses a load rhBMP the degradable support of 2 slow release system's the blood vessel realized transfer, this degradable support includes that the three -dimensional link up porous support, located the three -dimensional and link up the inside three -dimensional little support of porous support and be located the inside rhBMP of three -dimensional support a little 2 slow release system, three -dimensional little support is the porous net column structure that the three -dimensional link up, the middle part that the three -dimensional link up porous support sets up a central passage that link up from top to bottom, the third stand that the three -dimensional of control center passageway switching has a perfect understanding porous support can be dismantled and assemble. The utility model discloses a can the degradable support slowly release rhBMP 2, the vascularization that can realize the support simultaneously is in order to strengthen its skeletonization ability to bone tissue for new life provides good nutrients supply and excretes the metabolism wastes material, promotes it to the defective restoration ability of bone.
