Bone screw of three-dimensional through porous structure

The invention discloses a bone screw of a three-dimensional through porous structure. The porous bone screw comprises a screw head, a screw body and a screw cap. The screw body comprises a porous network composed of the three-dimensional through porous structure. The porous bone screw is made of medical materials which can be implanted into a human body, the three-dimensional through porous structure of the porous bone screw provides more space for the growth of bone cells, the combination between the implanted screw and the bone tissues of the human body is promoted, and the anchoring can be firm.
