This creation provides a kind of inter vertebral fusing device, and it includes an ontology and an at least fasteners. Wherein the ontology includes the engaging slot of at least one recess what body surface； Wherein an at least engaging slot includes that two opposite abutment faces and at least one set what two with respect to the chase between abutment face； An at least fastener is to be connected with the grade abutment faces of an at least engaging slot, makes to form an at least hole between an at least fastener and an at least chase for an at least engaging slot. When the inter vertebral fusing device what of this creation load bone and weight, the fastener can be provided by an at least hole because stress generates the admissible space of micro-elasticity deformation, and then makes more load stress effects what Psoralen region, to promote bone fusion to carry out.本創作提供一種椎間融合裝置，其包含一本體以及至少一卡合件。其中該本體包含至少一凹陷於該本體表面的卡合槽；其中該至少一卡合槽包含兩相對抵靠面以及至少一設於兩相對抵靠面之間的凹溝；該至少一卡合件，其係與該至少一卡合槽的該等抵靠面相連接，使該至少一卡合件與至少一卡合槽之至少一凹溝之間形成至少一孔洞。當本創作之椎間融合裝置於負載骨骼與體重時，可藉由該至少一孔洞提供該卡合件因受力產生微彈性變形之容許空間，進而使更多負載應力作用於補骨區域，以促進骨融合進行。
