Background
The cerebrovascular interventional operation including cerebrovascular angiography and cerebrovascular interventional therapy needs to be performed under guidance of DSA equipment, because DSA not only can clearly display vascular images of internal carotid artery, vertebrobasilar artery, intracranial great vessel and cerebral hemisphere, but also can measure blood flow of artery, so the DSA is currently applied to cerebrovascular disease examination, especially qualitative positioning diagnosis of aneurysm, arteriovenous malformation and the like, not only can provide exact position of lesion, but also can clearly know the range and severity of lesion, provides more reliable objective basis for operation, and has higher diagnostic value for ischemic cerebrovascular disease, DSA can clearly display arterial lumen stenosis, occlusion, collateral circulation establishment conditions and the like, and for cerebral hemorrhage, subarachnoid hemorrhage, further pinpoint the causes of hemorrhage, such as aneurysm, arteriovenous malformation and the like, In summary, DSA is an effective diagnostic method for cerebrovascular disease diagnosis, and the principle of cerebrovascular DSA image formation is to subtract an image acquired before injection of a contrast agent into a cerebral vessel from an image acquired after injection of the contrast agent.
The blood vessel image only containing the contrast agent is obtained after the processing of the computer, the same part of the image acquired twice is deleted, and if the skull of a patient shakes in the process of cerebral angiography, the generated subtraction image has artifacts, so that real vascular lesions are covered, and misdiagnosis is easily caused.
Therefore, it is necessary to develop a skull fixation device for cerebrovascular interventional procedures.
SUMMERY OF THE UTILITY MODEL
Therefore, the utility model provides a skull fixing device for cerebrovascular intervention operation to solve and obtain the blood vessel image that only contains the contrast medium after the computer processing, and the same part of the image of twice gathering is then deleted, if in cerebrovascular radiography in-process, the subtraction image that patient's skull rocked then the production will appear the artifact, has covered real vascular pathological change, causes the problem of misdiagnosis easily.
In order to achieve the above object, the present invention provides the following technical solutions: a skull fixing device for a cerebrovascular interventional operation comprises a supporting backup plate, wherein one end of the supporting backup plate is fixedly connected with an operating table, one end of the supporting backup plate, which is far away from the operating table, is fixedly connected with a U-shaped head support, a fan-shaped supporting pad is arranged on the inner side of the U-shaped head support, one side, which is close to the inner side of the U-shaped head support, of the fan-shaped supporting pad is arranged on the side wall of the fan-shaped supporting pad through a lifting component, clamping groove slideways are arranged at the left end and the right end of a supporting lifting keel, the two ends of the supporting backup plate are clamped in the clamping groove slideways, and adjustable fixing nuts matched with the clamping groove slideways are arranged in the two clamping groove slideways at the lower end of the supporting lifting keel;
the lifting component comprises a threaded rod, the top end of the threaded rod is rotatably connected with the bottom side wall of the U-shaped head support, the bottom end of the threaded rod is fixedly connected with a rotating disc, and a plurality of anti-slip strips are symmetrically and fixedly connected to the side wall of the rotating disc in the circumferential direction.
Preferably, the outer walls of the U-shaped head support and the supporting and lifting keel are provided with arc chamfers.
Preferably, the inner surface of the U-shaped head support is provided with an elastic layer.
The utility model has the advantages that: the utility model is connected with the operating table, and the inner surface is designed into a shell body corresponding to the appearance of the human head, thereby preventing the human head from moving during the operation, and the human head in the shell body is more comfortable through the elastic layer, and the braking effect is good; under the static state, the acquired digital subtraction angiography image is fresh, high in spatial resolution and sharp in image edge, plays a good role in helping to diagnose and treat intracranial vascular lesions, and reduces misdiagnosis.
