Topological optimization artificial vertebral body and design method thereof

The invention discloses a topological optimization artificial vertebral body and a design method thereof. The artificial vertebral body comprises a perforated topological thin-wall structure and a porous structure arranged in the perforated topological thin-wall structure, the topological thin-wall structure is used for lightweight design of the prosthesis on the basis of topological optimizationmethods in various motion gait mechanical environments, and on the basis of meeting the strength requirements of the prosthesis in different motion states, the porous structure is added to meet the bone ingrowth requirements, so that later biological fixation of the prosthesis is realized, and good stability is guaranteed. According to the topological optimization artificial vertebral body, through organic combination of the perforated topological thin-wall structure and the porous structure, the immediate stability and the middle-long-term stability of the implanted artificial vertebral bodycan be guaranteed at the s
