The invention relates to an assembled vertebral body used in a cervical reconstruction operation, comprising: an upper connecting element, an artificial vertebral body element and a lower connecting element, wherein the upper connecting element is disposed at an upper part of the artificial vertebral body element, the lower connecting element is disposed at an lower part of the artificial vertebral body element, and wherein the artificial vertebral body element is assembled with the upper connecting element and the lower connecting element, respectively. The invention has the advantages that the artificial vertebral body element is customized in accordance with the characteristics of patients and printed in 3D, and the length of the artificial vertebral body element can be precisely adjusted to adapt to the patient. Since the lower connecting element is standard part, the upper connecting element is standard part or non-standard part, and the artificial vertebral body element is non-standard part, in comparison to the traditional 3D printing which needs to be printed integrally, the adjustable assembled artificial vertebral body can reduce 3D printing materials and reduce the cost …
