Problems solved by technology
There are large errors in this manual detection method. In addition, manual detection is relatively slow and will increase the cost of the manufacturing process.
However, the existing visual automatic detection equipment is extremely complicated, and the price of the whole set of equipment is also very expensive.

Embodiment Construction
[0018] Various preferred embodiments of the invention are discussed below. However, those skilled in the art should understand that the detailed description herein is not intended to limit the protection scope of the present invention, and the present invention can also be realized through the modification of the following embodiments or other equivalent methods.
[0019] Some defects may appear after stent processing, such as figure 1 shown. Therefore, it is necessary to detect the consistency of the diameter and width of each part of the bracket, whether the shape meets the requirements, and the wall thickness.
[0020] figure 2 A stent detection system according to one embodiment of the invention is shown. As shown in the figure, the detection system includes a two-dimensional motion platform, an electronic linear array CCD, an external light source, an image processing device, and a display device.
[0021] A two-dimensional motion platform is used to move the scaffol...

The invention discloses a medical bracket detecting method. The medical bracket detecting method comprises the following steps: moving a medical bracket sample so that each area of the medical bracket sample can be detected conveniently; using an external light source to radiate light to the outer surface area of the medical bracket sample; and scanning the medical bracket sample in a line-by-line scanning mode to acquire an overall image of the medical bracket sample; and processing data of the image and displaying a processing result. In addition, a quartz rod is installed with the medical bracket sample in a matched mode so that the medical bracket sample can be in linkage with the quartz rod, wherein the outer diameter of the quartz rod is matched with the inner diameter of the medical bracket sample. When the external light source radiates the light to the quartz rod, the quartz rod emits white fluorescent light to radiate the white fluorescent light to the inner surface area of the medical bracket sample.
Description
[0001] technical field [0002] The invention relates to a thin-walled tube laser micromachining technology, in particular to a detection method for a medical bracket. [0003] Background technique [0004] A medical stent implanted in a blood vessel can act as a support frame to keep the blood vessel open. Medical stents must meet strict working requirements. If the stent contains any rough or sharp edges, it will damage the blood cells or the vessel wall where the stent is implanted, which will lead to further vascular disease, which is potentially life-threatening. Stents are generally small in diameter, about 1mm in diameter. After the laser cutting process, the size of various cutting features on the stent is about 50~200um. Generally, small changes in manufacturing process parameters, such as laser power, tube diameter or mechanical chatter, can cause defects. Since the functional failure of the stent may lead to life-threatening, the detection link after the stent ...
