| titleOfInvention | Composite artificial ligament and method of making the same |
| abstract | The invention belongs to the technical field of medical materials, and provides a composite artificial ligament and a manufacturing method thereof. PET yarn is selected as an inner layer, a PCL solution is spun onto the inner layer to obtain a PCL layer, and then a gelatin solution is spun onto the PCL layer. The gelatin outer layer is obtained from the above to form a single fiber with a three-layer structure, and then in the order of bone tunnel spinning, joint cavity spinning and bone tunnel spinning, the first bone tunnel part and the joint cavity part connected in turn are woven into the first bone tunnel part and the joint cavity part. and a three-dimensional knitted scaffold composed of part of the second bone tunnel, and the three-dimensional knitted scaffold is rolled up to obtain a composite artificial ligament. As the biodegradable material degrades, the surrounding tissue is attached to the graft, the ligament itself will climb and grow into the graft, and the non-degradable material provides permanent mechanical strength support, so the preparation method is simple, and the obtained composite The artificial ligament can promote the fusion of the artificial ligament and the bone tunnel, and has good mechanical properties, biocompatibility and good clinical application prospects. |
