The invention relates to a high-strength absorbable wire composited
internal fixation implantable device and a preparation method of the device, in particular to an
internal fixation implantable device taking high-strength
magnesium alloy wires in high content as a
basal body, wherein the high-strength
magnesium alloy wires are bonded and cured at a high temperature by low-content binder
polylactic acid polymers and are arranged in a directional dispersion way or in a two-dimension weaving structure or three-dimension weaving structure, and the binder
polylactic acid polymers account for 5%-49.9% of the total amount and the
magnesium alloy wires account for 50.1%-95% of the total amount according to the weight percentage. The high-strength absorbable wire composited
internal fixation implantable device is closer to the
magnesium alloy on the aspect of strength, can meet the mechanism safety requirements for large-load fracture fixation with higher strength requirement, and has the advantages of both controllable uniform internal absorption, slow and less
hydrogen degradation and separation, etc., thereby being particularly applicable to clinics like departments of bone
traumatology, department of
bone defect repair, plastic and beauty operations and the like with high strength requirement and
large size.
