Abstract

The invention relates to a composite artificial ligament and a preparation method thereof. The composite artificial ligament has a rodlike structure formed by reeling of a woven net. The woven net has a net structure formed by weaving of threads. The threads in the rodlike structure tangle with each other to loop together so as to form a mesh interleaving structure. The threads are formed by winding of a variety of filament bundles with different degradation properties, and the variety of filament bundles with different degradation properties are respectively formed by spinning or beam spinning of components with different degradation properties, so that the obtained composite artificial ligament has gradient degradation performance. The composite artificial ligament provided by the invention has good mechanical properties, and can promote the attachment of surrounding tissue and the repair and normal growth of ligament tissue. At the same time, part of components in the body can be gradually biodegradable, and significant decline of the ligament's mechanical properties cannot be caused during degradation.

Description

technical field

[0001] The invention relates to the technical field of implantable medical devices, in particular to a composite artificial ligament and a preparation method thereof. Background technique

[0002] Due to the special biological environment in the knee joint and the limitation of the blood supply of the cruciate ligament, the body of the cruciate ligament has no natural healing ability after rupture, so ligament reconstruction is required. Restorative materials include autografts, allografts, and artificial ligaments. Autologous transplantation has problems such as insufficient donor site and donor site complications, and allogeneic transplantation has the risk of delayed ligamentization, immune rejection, and even the risk of disease transmission. In contrast, artificial ligaments have the advantages of simple operation, reliable and controllable material sources, no damage to autologous tissue, and good postoperative stability, and are more widely used in li...
