Abstract

The invention discloses an auxiliary in-vivo ectopic bone formation device used for treating massive bone defect. The auxiliary in-vivo ectopic bone formation device used for treating massive bone defect comprises a main body portion; the main body portion comprises a top plate, a side plate and a bottom plate; the side plate is arranged, in lap joint, between the top plate and the bottom plate; the side plate is a component which bends to one side; and a cavity with a single-side opening is enclosed by the top plate, the side plate and the bottom plate. The auxiliary in-vivo ectopic bone formation device used for treating massive bone defect further comprises an infusion tube; and the infusion tube is in detachable communication with the cavity so as to allow nutrient solution delivery for bone formation during heterotopic osteogenesis. The auxiliary in-vivo ectopic bone formation device used for treating massive bone defect provided by the invention is suitable for ectopic bone formation in the treatment of massive bone defect; moreover, the device is rational in structure and smartly designed. By arranging the opening for setting up tissue engineering scaffolds and allogeneic bone materials, as well as arranging a plurality of micropores on the side plate used for enclosing the cavity, the auxiliary in-vivo ectopic bone formation device used for treating massive bone defectis capable of effectively ensuring material exchange so as to improve treatment effects of massive bone defect.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and in particular to an auxiliary body heterotopic bone formation device for the treatment of large-segment bone defects. Background technique [0002] In recent years, with the rapid development of bone tissue engineering, the application of bone tissue engineering technology to treat bone defects is the current development trend. Compared with in situ osteogenesis, the heterotopic osteogenesis model can reduce the variables that affect osteogenesis in the experiment and can evaluate the diaphysis The effect of cells and osteogenic materials. Heterotopic ossification (HO) refers to ectopic bone formation in the normal soft group other than bone tissue, which is a dynamic development process; heterotopic ossification is a kind of heterotopic ossification. [0003] Patent CN1279973C discloses an injected gel-type bone repair bioactive material and its preparation method. Each unit of the materia...
