The invention relates to a
bone grafting device for
tubular bone defect healing, and belongs to the technical field of orthopedic medical devices. The
bone grafting device is used for
grafting tubular bones to promote the healing of the tubular bones, and comprises an outer sleeve, an inner sleeve and a connecting rod, wherein the inner
diameter of the outer sleeve is matched with the outer
diameter of the two ends of a
tubular bone defect part required for
bone grafting, and the inner sleeve is positioned in the outer sleeve; the connecting rod is inserted in the inner sleeve, and the
diameter of the connecting rod is matched with the inner diameter of the inner sleeve; and the length of the connecting rod is greater than that of the inner sleeve, and the inner sleeve and the outer sleeve are made of
biodegradable magnesium alloy. In the bone
grafting device, the connecting rod in the inner sleeve can firmly connect the two ends of a defective
tubular bone, a high-quality autologous
cancellous bone is filled between the inner sleeve and the outer sleeve to simultaneously play roles of bone
grafting and reinforced fixing, and the
biodegradable magnesium alloy has a function of inducing
bone formation, thereby the fracture healing is promoted. The bone grafting device has the advantages of firm bone grafting,
high intensity, early ambulation for patients, and good clinical effect.
