AI Technical Summary

Problems solved by technology

They are all high-molecular polymers, often have local effusion reactions and cause aseptic cysts, cannot be sterilized again, and are expensive
In addition, there is the same kind of bone implant material produced by Shanxi Bone Bank, but this material has difficulty in bone source and may cause the spread of human diseases
Or use autogenous bone, but this method damages the patient's own healthy bone

Embodiment Construction

[0023] Select "superior cattle" over 1 year old with slaughter permits and "first-class cattle" without physical defects in limbs as raw materials. Slaughtering methods (clean body by shower, stun by electric anesthesia, bloodletting by assassination, skinning and hair removal, evisceration, etc.) are all carried out in accordance with NY467-2001 standard. Immediately after slaughter, the brain tissue was taken for pathological examination and Western detection. The cattle were temporarily placed in a cold storage, and the bones were taken only after the results were negative. When taking limb bones, remove the fur, meat, hooves and joints, leaving the long bones of the limbs. The time from slaughtering of cattle to soaking of bones should be less than 24 hours. Choose fresh luster, no abnormal stains, deformities and defects, no adhesion of fur, muscle and dirt, no abnormal smell of bones. Put the bovine bone into a plastic bucket filled with 50% ethanol. Fresh beef bones ...

Abstract

This invention relates to a method for preparing replanting filling materials and synthetism fixity materials used in bone surgery treatment, also this invention relates to the method for making bone replanting filling stuff and synthetism fixity from those materials and the products. Besides normal quarantine entries, this invention can also inspect crazy heifer disease virus. By a preparing method of antigens heterogeneity bone, this invention can guarantee the products takes no crazy heifer disease virus or other diseases. Cost low but provide better products.

Description

technical field [0001] The present invention relates to a method for the preparation of graft filling materials and osteosynthetic fixation materials for use in orthopedic surgical treatments. At the same time, the present invention further relates to methods for preparing bone graft filling materials and osteosynthetic fixtures using such materials, as well as the resulting bone grafts and bone fixtures. technical background [0002] There are two main types of materials used in orthopedic surgery. [0003] One type is the fixture material. Except for a few non-metallic materials, most of the fixtures are metal materials. Metal materials: such as screws, round needles, intramedullary nails, bone plates, cages, etc., still occupy a large part of the market at home and abroad. Although they have high mechanical strength and fatigue resistance, they can meet the needs of orthopedic surgical fixation, but they may also have complications such as implant corrosion, metal al...
