Problems solved by technology

[0005] However, the above-mentioned angiography device can only adjust the imaging angle of X-rays on the detector 4 by sliding the crank arm 2 on a "C"-shaped track.
Therefore, in the actual operation process, it is often necessary for the patient 5 to turn over to obtain more angles of angiog...

Embodiment Construction

[0040] As mentioned in the background technology, most of the existing angiographic devices can only adjust the rays located at both ends of the "C"-shaped arm along the sliding track of the "C"-shaped arm through the sliding of the "C"-shaped arm. The imaging angle of the tube and detector relative to the patient. The existing angiographic apparatus has a single way of adjusting the imaging angle of the angiographic picture, and cannot obtain more imaging angles except along the sliding track of the "C"-shaped crank arm. In actual use, sometimes the patient needs to move cooperatively to obtain angiographic pictures from more angles, which increases the complexity and cumbersomeness of taking angiographic pictures.

[0041] To this end, the present invention provides an angiography device, the ray tube and detector on the angiography device can be adjusted around the patient in a 360° omnidirectional imaging angle, so as to obtain a full range of angiography pictures.

Abstract

The invention provides an angiography device. The angiography device comprises a first part, a second part and an annular third part, wherein the first part is fixed on an external foundation support through a first rotating shaft and can rotate along the axial direction of the first rotating shaft; the second part is fixedly connected with the first part through a second rotating shaft and rotates along the axial direction of the second rotating shaft; the third part is positioned on an annular track of the second part and can rotate along the center of the annular track. A ray tube and a detector for photographing an angiography picture are installed on the annular inner surface of the third part. When the angiography device is used, a patient is arranged in a ring of the third part, and the switching of 360-DEG omnibearing imaging angles of the ray tube and the detector on the patient can be realized by virtue of the rotation of the first part, the second part and the third part, so that under the situation that the body position of the patient is not changed, the angiography pictures of vascular morphology in different angles can be acquired, and the disease diagnosis information can be more comprehensively and accurately acquired.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an angiography device. Background technique [0002] Angiography is a method of detecting blood vessel disease by injecting a contrast agent into blood vessels and then taking pictures of blood vessels with X-rays. Based on the fact that X-rays cannot penetrate contrast agents, vascular lesions can be diagnosed through the images displayed by contrast agents under X-rays. Therefore, angiography can accurately reflect the location and degree of vascular lesions, thereby obtaining diagnostic information for vascular lesions. [0003] Nowadays, angiography technology is widely used in the clinical diagnosis and treatment of various cardiovascular diseases such as stroke, aneurysm, abdominal aortic aneurysm, etc. Angiography technology helps doctors to detect the disease in time, control the progress of the disease, and effectively improve the people's survival rate. [0004] refer to figur...
