Three-dimensional micro stent composite porous metal support for adhering blood platelets

The invention discloses a three-dimensional micro stent composite porous metal support for adhering blood platelets. The method for preparing the composite porous metal support for adhering blood platelets comprises the following steps: preparing a porous metal support by utilizing a 3D printing technology; preparing a three-dimensional micro stent inside the porous metal support by adopting a thermo-crosslinking method; and finally, performing freeze-drying on blood platelet-enriched plasma to be adhered to the three-dimensional micro stent. The composite porous metal support for adhering blood platelets provides the best growth microenvironment for growth of bone cells, cell factors can be slowly activated and released after the blood platelets subjected to freeze-drying treatment are hydrated, formation of bone tissues, fibrous tissues and new vessels is induced, and a good support material with biological activity is provided for clinical bone tissue repair.
