Abstract

The invention discloses an angiography catheter and a size measuring method. The angiography catheter comprises a catheter body, developing rings in first preset number are assembled on the catheter body, and the first preset number is a positive integer greater than 1; the developing rings have fixed positions on the catheter body and are uniformly arranged, and distance between each two adjacentdeveloping rings is a first preset distance which is greater than 0, so that the angiography catheter can realize a developing function, has a function of measuring physical size and can realize direct measuring of a target area in an angiographic image; compared with an indirect measuring mode of artificially selecting measuring points of the target area on the angiographic image and utilizing asoftware calculation mode to calculate size of the target area, the angiography catheter is higher in measuring accuracy and preciseness.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more particularly, to an angiography catheter and a dimension measurement method. Background technique [0002] Contrast imaging, in diagnostic radiology, injects a contrast agent into the aortic blood through the small opening in front of the catheter, so that X-rays can display the shape of blood vessels and the heart on the display screen with the contrast agent flowing along the blood vessels. [0003] At present, the judgment of the size and length of the vascular lesion is mainly through the basic angiography, and the doctor judges according to experience and then selects the follow-up treatment tool; or confirms the most suitable size by trying from small to large; the newer method is through The software measures the angiographic image to determine the size of the lesion. For example, coronary artery CT angiography method, this method captures the angiographic image, ...
