Abstract

The invention discloses a medical support detection device. The medical support detection device comprises 1, a roller device which is used for driving a support sample to rotate so that all areas of the support sample can be detected conveniently, 2, a transverse illumination light source which is used for illuminating an outer surface area of the support sample, 3, a longitudinal illumination light source which is used for illuminating an inner surface area of the support sample, 4, an electronic linear array CCD which is installed on the support sample and is used for scanning the support sample by a line-by-line scanning method to obtain the integral image of the support sample, 5, an image processing device which is coupled with the electronic linear array CCD and is used for processing the data acquired by the electronic linear array CCD, and 6, a display device which is coupled with the image processing device and is used for displaying the processing result obtained by the image processing device.

Description

technical field [0001] The invention relates to laser micromachining technology for thin-walled pipes, in particular to a detection device for medical brackets. Background technique [0002] A medical stent implanted in a blood vessel can act as a scaffold 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 . Generally, small changes in manufacturing process parameters, such as laser power, tube diameter or mechanical chatter, can cause defects. Because the functional failure of the stent may lead to life-threatening, the detection link after the stent processing is completed is particularly important. [0003] The existing detection methods include manual detection and automatic detection by visual system. Manual inspection is to ...
