Integrated support convenient to recycle and weaving method thereof

Abstract

The invention discloses an integrated support convenient to recycle. The integrated support comprises a framework portion which is formed by weaving one wire. The formwork comprises opening portions at two ends, more than two middle supporting portions connecting the opening portions at the two ends, and connection portions. The adjacent opening portions and the supporting portions are connected through the connection portions, and the adjacent supporting portions are connected through the connection portions. The opening portions, the supporting portions and the connection portions are formed by weaving one wire. The opening portions and the supporting portions are rhombic grids, and the connection portions are connected in a Z-shaped wave mode. The invention further discloses a weaving method of the integrated support convenient to recycle.

Description

Technical field [0001] The invention relates to medical equipment used for placing in various organ pipes (blood vessels, trachea, digestive tract, etc.) of the human body, in particular to an integrated stent that is easy to recycle and a preparation method thereof. Background technique [0002] At present, in the medical field, there are often diseases such as narrowing or obstruction of the lumen of the human body due to different reasons. In order to reduce the pain caused by the operation to the patient, interventional therapy has gradually developed. The therapy is to use a catheter to combine drugs or surgical equipment. One of the methods of sending to the lesion for treatment, the introduction of a highly elastic mesh stent is one of the important applications. [0003] Nowadays, the non-vascular stents in the lumen are mainly stents in a single braided way. In some lesions, their bending performance is not ideal, the radial support force is insufficient, and the axial sho...

AI Technical Summary

Problems solved by technology

[0003] At present, the stent in the non-vascular lumen is mainly based on a single braided stent. In some pathological conditions, its bending performance is not ideal, the radial support force is not enough, and the axial shortening rate after insertion is relatively large, resulting in more complications. , leading to secondary surgery and other problems in severe cases

At the same time, the recycling of such brackets has always been troublesome.

[0004] At first, the stent cannot be recovered after being implanted in the human body. Once the stent is placed in an improper position or the patient has serious complications, and the stent cannot be removed safely and effectively in a timely manner, serious medical accidents will occur.
