Bone graft capable of being directly implanted into intervertenral space and production tool thereof

The invention provides a bone graft capable of being directly implanted into an intervertenral space. The bone graft is produced by compacting broken bone pieces obtained by pressure reduction in operations into a body of a required shape by a corresponding production tool, and can be directly implanted into an intervertenral space. The bone graft has certain compression resistance, can effectively support and maintain the intervertenral height, is not liable to break and has high safety. The bone graft does not need a fusing machine as a carrier, thus enlarging the contact area between the upper and lower end plate interfaces between the bone graft and a vertebral body, and being favorable for bone fusion. Moreover, the bone graft greatly reduces the operation cost, relieves patients of expensive treatment, and can be extensively applied to intervertenral bone graft fusion operations in hospitals. The invention also provides a production tool for producing the bone graft, the cavity depth of the production tool is set in proportion according to the thickness of the bone graft, spacing structures are arranged for limiting the depth of pressing a die block into a die cavity, and during compaction, the thickness of the bone graft can be obtained by filling broken bone pieces in the die cavity and compacting until the two spacing structures are in contact, so that the production tool is simple and convenient in operation and strong in practicability.
