The invention discloses an internal spinal support structure, which comprises a cone internal support. The bracket in the cone is a hollow tubular body made of memory metal material. There are several grooves on the bracket in the cone, among which a deformation area is formed. The deformation area can support the bracket in the cone to expand outwards； when the deformation area of the bracket in the cone can shrink inwards to straight flakes at low temperature, it will return to expand outwards after the temperature rises.本創作揭露一種脊椎內支架結構，其包含一錐體內支架。該錐體內支架為一種記憶金屬材料製成的中空管狀體，錐體內支架上剖設有若干道剖槽，各剖槽之間形成變形區域，該變形區域可將錐體內支架支撐成向外擴張狀；當錐體內支架之變形區域在低溫下可以內縮成直片狀，又在溫度提升後，恢復成向外擴張的態樣。
