A kind of preparation method of allogeneic or xenogeneic tendon and bone-tendon complex |
| abstract |
The present invention relates to a preparation method of allogeneic or xenogeneic tendon and bone-tendon complex, comprising the following steps: S1: obtaining allogeneic or xenogeneic tendon and bone-tendon complex material, and using purified water to clean the blood stains on the surface of the tendon ; S2: turn on the supercritical CO 2 extraction equipment, and place the cleaned tendon in the supercritical CO 2 extraction equipment for extraction; S3: perform decellularization treatment and oil washing on the extracted tendon; S4: Add purified water to the tendon after shaking and washing, and perform shaking and washing in a shaker at room temperature; S5: Trim the tendon after shaking and washing, and drain the water on the surface of the trimmed tendon. Vacuum packaging is carried out under the conditions; S6: the vacuum-packaged tendon is made by using cobalt-60 to irradiate the packaged tendon at a dose of 10-30 kGy and then sterilized again. The invention has the advantages of convenient processing, high efficiency, environmental protection and safety. |
