摘要：
Disclosed is an artificial axis support body, applicable to the technical field of medical apparatuses. The artificial axis support body comprises a supporting body (1). The supporting body (1) comprises a crown part and a body part. A top profiling face is formed on the top face of the crown part, and a bottom profiling face is formed on the bottom face of the body part. A cavity is formed inside the supporting body (1). A porous grid bracket (4) is arranged inside the cavity. On the surface of the supporting body (1), a plurality of windows (11) are formed inside the cavity. A lower fixing lug (5) is arranged at the bottom end of the body part, and upper fixing lugs (6) are arranged at the top end of the crown part. Both the upper fixing lugs (6) and the lower fixing lug (5) are provided with fixing holes. The supporting body (1) can be tightly connected to an atlas (2) by virtue of screws. The supporting body (1) can be tightly connected to a third cervical vertebra (3) by virtue of screws. The supporting body (1), by virtue of the upper and lower profiling faces, can form a dissecting fit. Meanwhile, the upper fixing lugs (6) are connected to the atlas (2) and the lower fixing lug (5) is connected to the third cervical vertebra (3), so that the artificial axis support body has a good supporting and reconstruction stability and is capable of preventing a prosthesis from becoming loosened and failing after an operation. The artificial axis support body is easily to fix, has a good shape matching performance, a low fixation failure rate after the operation and a high fusion rate； therefore, the artificial axis support body can meet the demands of complex operations.L'invention concerne un corps de support d'axe artificiel, applicable au domaine technique des appareils médicaux.
