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 c

Embodiment 1

[0042] like figure 1 As shown, in this embodiment, when a bracket consisting of two opening parts 1 at the beginning and the end, three supporting parts 2 in the middle and four connecting parts 3 is to be prepared, the preparation method is as follows:

[0043] like figure 2 as shown,

[0044] The weaving method of the integrated bracket in this embodiment is done on the cylinder weaving mold 6 . The mold 6 includes head ends 6a on both sides and a middle part 6b, wherein the head ends 6a have grooves 6a1 in the same direction as the axis oo', and there are multiple grooves arranged at intervals around the head ends 6a. A circle of steel wire rope 6a2 is wound on the outer circumference of the top of the die head, and a group of small holes 6b1 are arranged on the middle part 6b. Fixing nails are arranged in the small holes 6b1 for making rhombus grids for shaping. The compilation steps are as follows:

[0045] like figure 2 As shown, step 1, start from the diamond-sha...

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 for placing in various organ pipelines (blood vessels, trachea and digestive tract pipelines, etc.) of the human body, in particular to an integrated stent that is easy to recycle and its preparation method. Background technique [0002] At present, in the medical field, there are often diseases such as stenosis or obstruction of the lumen in the human body due to different reasons. In order to alleviate the pain caused by the operation, interventional therapy has gradually developed. It is a method to send to the lesion for treatment, and the introduction of highly elastic mesh stent is one of the important application methods. [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, resultin...
