Abstract
Description
Technical Field
[0001] The present application relates to the technical field of special body position support for magnetic resonance imaging, and in particular to a support and protective gear for magnetic resonance imaging examination of the cervical spine in hyperextension and hyperflexion positions. Background Art
[0002] At present, magnetic resonance imaging has a very important application in the imaging of the spine, especially cervical spine diseases, including cervical degenerative lesions, tumor lesions and other types of diseases. Usually, for magnetic resonance imaging of the cervical spine, the examination position is often in the supine position, which ignores the dynamic compression of the cervical spine and cannot reflect the changes in the dynamic position of the spinal cord tissue structure. Hyperextension and hyperflexion solve these problems. However, since the magnetic resonance imaging examination time is relatively long, how to support and protect the patient's cervical spine while maintaining sufficient hyperextension and hyperflexion angles is crucial to the imaging results.
[0003] Hyperextension and hyperflexion are two different positions of the cervical spine. Sufficient physiological extension and flexion angles are the key to discovering lesions. For magnetic resonance imaging of the cervical spine, the radio frequency coil often uses a head-neck combined coil or a dedicated spine coil. Currently, when performing hyperextension and hyperflexion magnetic resonance imaging of the cervical spine, sponge pads and other methods are often used for support. However, due to the different thickness of the sponge pads, the thickness cannot be adjusted arbitrarily. At the same time, the sponge pads will gradually shrink under long-term pressure, resulting in changes in the angle and missed diagnosis of lesions.
[0004] In addition, some patients with cervical spine diseases are often accompanied by symptoms such as pain. Therefore, neck support in hyperextension position and head support in hyperflexion position are important factors that restrict the success rate of the examination.
[0005] Therefore, there is an urgent need for a universal support brace for cervical hyperextension and hyperflexion magnetic resonance imaging examinations. Utility Model Content

[0025] The support and brace for MRI examination of cervical vertebrae in hyperextension and hyperflexion position of the present application is mainly used for support and protection during MRI examination of cervical vertebrae in hyperextension and hyperflexion position. It has a simple structure and universal applicability, and can be applied to different types of radio frequency coils and patients of different body shapes. By setting a head and neck limiting device 10 that matches the physiological characteristics of the human head and neck, when the patient lies on his back, the head and neck fall into the head and neck limiting device 10. Specifically, the headrest falls into the occipital support area 11, and the neck and shoulder fall into the neck and shoulder support area 12, so as to achieve precise limiting of the patient's head and neck, and the head and neck limiting device 10 can fit the radio frequency coil.

[0026] For example, in the support brace for cervical vertebra hyperextension and hyperflexion magnetic resonance imaging examination provided in one embodiment, Figure 1-2 As shown, the angle adjustment device 20 is located below the head and neck limiting device 10 and abuts against the occipital support area 11 to control the cervical vertebra hyperflexion angle; or the angle adjustment device 20 is located below the head and neck limiting device 10 and abuts against the cervical shoulder support area 12 to control the cervical vertebra hyperextension angle.

[0033] For example, in the support brace for cervical vertebra hyperextension and hyperflexion magnetic resonance imaging examination provided in one embodiment, Figure 3 As shown, the height adjustment device 30 is located below the head and neck limiting device 10 and on both sides of the support rod 22 to support the head and neck limiting device 10. Specifically, the left side neck support pad 31 is located on the left side of the patient's neck, and the right side neck support pad 32 is located on the right side of the patient's neck, so as to achieve all-round height support when the patient's neck is in hyperextension and hyperflexion. The height adjustment device 30 is composed of several sponge pads, which are comfortable and soft, can meet the use requirements of different hyperextension and hyperflexion angles, and maintain this position for a long time for examination, thereby improving the comfort of the patient's examination.
[0034] For example, in the support brace for cervical vertebra hyperextension and hyperflexion magnetic resonance imaging examination provided in one embodiment, Figure 3 As shown, the left side neck support pad 31 and the right side neck support pad 32 are symmetrical structures, and the height is adjusted by adjusting the number of sponge pads of the left side neck support pad 31 and the right side neck support pad 32. Specifically, when the left side neck support pad 31 and the right side neck support pad 32 are used at the same time, they are used for hyperextension examination, and the two are respectively located on both sides of the neck to fit the neck tissue, and the height is adjusted by adjusting the number of sponge pads, and the air is squeezed at the same time to improve the image signal-to-noise ratio; when only the right side neck support pad 32 is used, it is used for hyperflexion examination, and the hyperflexion fits the occipital region, and the height is adjusted by adjusting the number of sponge pads.
