Head threaded rod adjustment and fixation device for cardiovascular and cerebrovascular imaging

Abstract

The invention discloses a threaded rod adjusting and fixing device for head cardio-cerebral angiography. The device comprises an upper fixing ring, a right threaded adjusting device, a lower fixing ring and a left threaded adjusting device; the left threaded adjusting device is provided with a first threaded rod, the first threaded rod penetrates through a second threaded pipe, the lower end of the second threaded pipe is fixed to a first threaded pipe, a second threaded rod is inserted in the first threaded pipe, and the right threaded adjusting device is provided with the same structure as the left threaded adjusting device; the upper fixing ring is provided with two half fixing rings, the upper end of each half fixing ring is fixedly provided with a closing plate, two main fixing devices are centrosymmetrically arranged at the lower ends of the closing plates, a secondary fixing device is arranged at the portion, on the corresponding half fixing ring, of the lower end of each main fixing device, and the lower fixing ring is provided with the same structure as the upper fixing ring. By means of the head threaded rod adjusting and fixing device for the cardio-cerebral angiography,the head is fixed stably, and the device is applicable to different persons who has heads different in length and faces different in width.

Description

technical field [0001] The invention relates to a threaded head adjusting and fixing device, in particular to a head threading rod adjusting and fixing device for cardio-cerebral angiography. Background technique [0002] Cardiovascular and cerebrovascular accidents are a common disease that seriously threatens the health of human beings, especially middle-aged and elderly people over 50 years old. Even if the most advanced and perfect treatment methods are applied, more than 50% of cerebrovascular accident survivors cannot fully take care of themselves. The number of people who die from cardiovascular and cerebrovascular diseases is as high as 15 million every year in the world, ranking first among various causes of death. Cardiovascular and cerebrovascular diseases have become the number one killer with the highest cause of death for human beings, and they are also the "silent evil spirits" of people's health.

Problems solved by technology

[0003] When a patient undergoes cardiac and cerebral angiography, the patient usually needs to lie on the contrast table, and then fix the head and body to prevent the image from being blurred due to shaking of the head or body. However, different people have different heads, and their proportions are also different. , the existing fixing devices are all adjusted as a whole, which cannot be well applied to different groups of people, and the fixing effect is poor
