Embodiment Construction

[0018] Such as figure 1 As shown, the support of the present invention includes an outer network pipe 1 and an inner network pipe 3, the inner network pipe 3 and the outer network pipe 1 are straight pipes with densely distributed meshes 4 on the pipe wall, and the diameter of the meshes 4 on the inner and outer network pipes is between 2.8- It is better between 3.2mm, because the diameter of the bone crushed bone particles is generally about 4mm, so the mesh can be made as large as possible under the premise that the bone crushed bone particles can be effectively blocked.

[0019] The external network management 1 is socketed outside the internal network management 3, and the two ports of the internal network management 3 are located on the inside of the two port planes of the external network management 1 respectively, and the port planes of the internal network management 3 are connected to the adjacent ports of the external network management 1. The distance between the po...

Abstract

The invention relates to an auxiliary bone grafting bracket for a large bone defect, which has the structure that an outer mesh pipe is sleeved outside an inner mesh pipe; a plurality of connecting rods are connected between the outer wall of the inner mesh pipe and the inner wall of the outer mesh pipe; the pipe walls of the inner mesh pipe and the outer mesh pipe are distributed with meshes; and both ports of the inner mesh pipe are respectively positioned at the inner sides of both port planes of the outer mesh pipe. The bone compensating bracket is suitable for the bone defect treatment of a wound without inflammation. By grafting the bone compensating bracket into the bone defect part of a patient, the curing effect of a bone defect disease can be effectively improved, and a feasible, practical and efficient new scheme is provided for the treatment of the large bone defect.

Description

technical field [0001] The invention relates to an autologous bone graft treatment appliance, in particular to an auxiliary bone graft bracket for large segmental bone defects. Background technique [0002] At present, for the treatment of large bone defects, it is generally through intramedullary nails and steel plate reinforcement. These bone fragments are piled up and implanted in the bone defect of the limb, and finally the bone graft can survive in the bone defect, the medullary cavity can be recanalized, and the bone defect can be healed. The disadvantages of this bone-crushing treatment method are: first, the osteogenic units are not concentrated, resulting in a large amount of bone harvested and used; second, the central medullary cavity cannot be formed in the early stage, which is not conducive to blood flow; Bone is often absorbed by the soft tissue of the affected area, resulting in treatment failure; Fourth, the long course of treatment increases the pain of th...
