Embodiment 1

[0032] Embodiment 1, the preparation of magnetized allograft bone

[0033] 1. Preparation of magnetized allograft bone:

[0034] according to figure 1 The preparation process of the magnetized allogeneic bone of the present invention shown in the present invention is to prepare the magnetized allogeneic bone. The following operations are all completed in the ultra-close workbench:

[0035] Freeze-dried cancellous bone blocks were prepared from the ilium of rabbits under aseptic conditions, and the cancellous bone blocks were evenly cut into slices. The length, width, and height of the bone slices were 5mm×5mm×2mm. a square groove (such as figure 2 (b) shown). as per image 3 As shown in the flow chart, apply the magnetic adhesive mixed uniformly with iron ferric oxide and bone cement at a ratio of 1:10 to the prepared cancellous bone cut surface (the thickness of the magnetic adhesive layer after bonding is 1mm), and bond it , put the bonded cancellous bone into a static...

Abstract

The invention discloses a magnetized allogeneic bone and a preparation method and application thereof. The preparation method of the magnetized allogeneic bone includes steps: adding a magnetic material into allogeneic bone; putting in a magnetic field, magnetizing and solidifying to obtain magnetized allogeneic bone. A magnetic adhesive and the allogeneic bone are mixed and put in the magnetic field to obtain magnetic field intensity. The magnetized allogeneic bone is applied to preparation of allogeneic bone materials for in-vivo implantation.

Description

technical field [0001] The invention relates to a magnetized allograft bone and a preparation method and application thereof, belonging to the field of biomedical engineering. Background technique [0002] Allograft bone is allograft bone, which is widely used in the field of orthopedics. Allograft bone is one of the important ways to reconstruct bone defect after tumor resection, and it is generally divided into structural bone graft and filling bone graft. Its advantages are as follows: 1. A wide range of materials can be obtained, and the dosage is not limited; 2. The structure similar to that of the patient's resected bone can be obtained during structural bone grafting; 3. Better functions can be obtained after healing. The disadvantages are: 1. Immediate stability cannot be obtained, and bone healing time needs to be waited for; 2. Allogeneic bone rejection, absorption, and nonunion may exist. Bone cement is also a commonly used bone tissue repair material. Most stu...
