The invention relates to an
artificial bone with a porous laminated structure and passages, which belongs to the technical field of biomedical materials. The
artificial bone is alternately laminated and formed by compact
layers and porous
layers which are made of
calcium phosphate base biological
ceramic materials, and in addition, passages for conveying cells and
body fluid are arranged in the direction which forms a set angle with the laminated
layers. The preparation method comprises the following step: mixing
powder such as
hydroxylapatite, beta-
tricalcium phosphate and the like through using deionized water as medium to be prepared into pulp. A three-dimensional gel laminated forming
system is adopted for preparing
ceramic blanks formed by the compact layers, the porous layers and the passages, and then the
ceramic blanks are sintered at a high temperature for preparing the
artificial bone. The invention has the characteristics that the artificial bone has high
mechanical strength, has the porous structure with the effects of osteoplast adhesion, propagation, growth and vascularization, can be used as the artificial bone, can also be used as a
bone tissue engineering support frame, and has wide application prospects in clinics in the orthopedics department.
