技术领域technical field
本实用新型涉及微创医疗器械领域，特别涉及介入血管内部的一种显影支架。The utility model relates to the field of minimally invasive medical instruments, in particular to a developing support for intervening inside blood vessels.
背景技术Background technique
周边血管手术是传统的治疗周边血管狭窄的方法，而支架治疗法相较于传统的周边血管手术，其采用支架治疗的微创介入手术创伤小，并发症少，效果好，成为目前治疗周边血管狭窄的主要办法。血管支架在X射线机或其他医学影像设备下的显影性能，在手术过程中和手术后都对临床效果起到至关重要的作用。在手术过程中，操作者需要借助血管支架的显影性能来准确地定位和释放支架。Peripheral vascular surgery is a traditional method for treating peripheral vascular stenosis. Compared with traditional peripheral vascular surgery, stent therapy is a minimally invasive interventional operation with less trauma, fewer complications, and better results. It has become the current treatment for peripheral vascular stenosis. main method. The imaging performance of vascular stents under X-ray machines or other medical imaging equipment plays a vital role in the clinical effect during and after the operation. During the operation, the operator needs to accurately position and release the stent with the help of the visualization performance of the vascular stent.
传统的血管支架采用显影环或者显影标记，显影环或显影标记容易脱落，所以对加工工艺要求较高，且增加标记容易使血管支架的局部外径较大，影响支架的应力分布及柔软性；显影编织丝成本较高，整体采用显影编制而成的支架价格较为高昂，易造成贵金属的浪费。Traditional vascular stents use developing rings or developing marks, which are easy to fall off, so the requirements for processing technology are high, and adding marks will easily make the local outer diameter of the vascular stent larger, affecting the stress distribution and flexibility of the stent; The cost of developing braided wire is relatively high, and the overall price of the bracket made of developing braid is relatively high, which is easy to cause waste of precious metals.
血管内壁是非规则的内壁，其直径非一致的，一般呈渐变状，直径逐渐变大或者变小。 The inner wall of the blood vessel is an irregular inner wall with non-uniform diameter, generally in a gradual shape, and the diameter gradually becomes larger or smaller.
现有技术中的血管支架为圆柱状，支架介入血管内部时，易对血管内壁造成压迫或者导致支架支撑不到位的现象发生。 The vascular stent in the prior art is cylindrical, and when the stent is inserted into the blood vessel, it is easy to cause compression on the inner wall of the blood vessel or cause the phenomenon that the support of the stent is not in place.
