Abstract

The invention discloses a medical zinc alloy bracket and a production method thereof, belonging to the technical field of medical materials. The alloy element content of the stent is low, and the continuous drawing high plasticity and annealing strengthening and toughening effect of the wire material are not available in other biomedical degradable alloy wire materials. According to this characteristic, the continuously drawn zinc alloy wire material in the present invention can be seamlessly connected to a support braiding machine to be woven into a support product, and the production efficiency is extremely high. After the braided stent is annealed, the structural strength is greatly improved, the radial support force of the stent is increased, and the internal stress caused by drawing and braiding in the zinc alloy wire is weakened at the same time. The above characteristics are enough to show that the medical zinc alloy stent and its production method described in the present invention can realize large-scale high-efficiency production, and due to the high plasticity of the wire after drawing, the broken wire rate of the stent product is low, and can maintain a relatively high temperature. High bracket yield.

Description

technical field

[0001] The invention belongs to the technical field of medical materials, and in particular relates to a medical zinc alloy bracket and a production method thereof. Background technique

[0002] Magnesium-based, iron-based and zinc-based alloys are currently three biodegradable medical metal materials with promising application prospects. Iron-based alloys have outstanding mechanical properties, but the degradation is extremely slow and the degradation products are easy to accumulate and cause negative effects on the human body. Magnesium-based alloys have good biocompatibility in the human body. However, due to its very active chemical properties, it degrades too quickly in the human environment and loses the integrity of its mechanical properties prematurely. In most cases, it cannot be used until the affected area is cured. Zinc has a degradation rate between magnesium and iron. It is an essential trace element in the human body and participates in vario...
