Lumbosacral nerve bowstring refers to the occurrence of axial high tension and further a series of nerve injury related symptoms due to lumbosacral nerve traction caused by congenital developmental factors, spinal cord degeneration factors, iatrogenic injuries. The disease may be accompanied by the occurrence of other lumbosacral diseases such as herniated disc, spinal stenosis, lumbar spondylolisthesis, scoliosis, and the like. The axial tension of the dura sac and the nerve roots of the patient is increased, and the pain symptoms of the waist and the legs of the patient are aggravated along with the increase of the tension, like a string which is tightened, the larger the pulling force is, the more the sound which is generated by stirring is flood and bright, and the shape of the lumbar sacrum part of the spine is just like a bow, so the disease is named as lumbosacral nerve bowstring disease. The clinical symptoms of lumbosacral nerve bowstring disease are pain in the back, pain in lying down and morning hours, can be aggravated by bending over, difficulty in sedentary sitting, numbness of the limbs on both sides or one side, weakness.

The sickbed assembly 100 can be used with the magnetic resonance coil 200, and can fix the position of the part to be scanned of the patient 300 and the position of the magnetic resonance coil 200 in the magnetic resonance device, so that the space superposition coincidence of two magnetic resonance images obtained by front and back scanning of the leg lifting and/or the leg pressing can be realized, and whether certain diseases, such as bowstring disease of nerve bundle tension, exist can be diagnosed by comparing the displacement of certain tissues of the two images. Specifically, the magnetic resonance coil 200 is disposed below the patient bed assembly 100. The magnetic resonance coil 200 can acquire image information of spinal cord and lumbosacral nerve, and determine whether the nerve bundles have tension by comparing the motion differences of the nerve bundles in different limb states, thereby obtaining whether the patient 300 suffers from lumbosacral nerve bowstring disease. The magnetic resonance coil 200 is prior art and its specific structure is not described in detail here.

One end of the support 3 is connected to the support plate 2, and the other end is selectively inserted into one of the insertion grooves 102 to be configured to be capable of supporting the support plate 2 to be inclined to different angles. The number of the lifting mechanisms can be one or two. When the lifting mechanism is one, and the patient 300 needs to be moved when the left leg and the right leg of the patient 300 need to be detected, the operation is complicated, so that two lifting mechanisms are preferably provided in the present embodiment, each corresponding to one leg of the patient 300.
In this embodiment, by providing two lifting mechanisms arranged side by side, the left leg and the right leg of the patient 300 can be independently supported and lifted, so that one or both legs of the patient 300 are lifted to a specific height, and the patient 300 has a plurality of different limb states. At this time, by detecting the displacement of the spinal cord and the lumbosacral nerve of the patient 300 in different limb states, it can be determined whether the patient 300 suffers from lumbosacral nerve bowstring disease. Compared with the prior art that the experimenter is required to manually lift the legs of the patient 300 to different heights for many times, the patient bed assembly 100 is convenient to operate, the number of the experimenters can be effectively reduced, the stability of the legs of the patient 300 in the detection process can be improved, and the detection precision and the detection efficiency can be improved.

The using method of the magnetic resonance system comprises the following steps:
first, when the magnetic resonance system is used to perform a magnetic resonance examination on the patient 300, the purpose of controlling the elevation of the left and right lower limbs by a specific angle can be achieved by adjusting the inclination angle of the support plate 2 supporting the leg of the patient 300 without moving the body of the patient 300, and thus, images of the patient 300 at different elevation angles of the lower limbs while the body of the patient 300 remains stationary can be acquired by the magnetic resonance coil 200. By using a scanning technique of particular contrast, the structure of the lumbosacral nerve of the back of the patient 300 can be observed.
Then, by registering the anatomy of the lumbosacral nerve of the patient 300 in different leg lifting states, the spatial positions of the characteristic anatomical points of the lumbosacral nerve are calibrated, and the nerve length and direction between the characteristic anatomical points are measured.
Finally, the length and direction changes of the nerve measured when the lower limb level of the patient 300 is measured and compared with the different leg lifting heights are used for evaluating the tension of the lumbosacral nerve, and an imaging basis is provided for the diagnosis of bowstring disease.
In this embodiment, as shown in fig. 3, the method for applying magnetic resonance system scanning includes the following steps:
the patient 300 is carried on the sickbed assembly, and the legs of the patient 300 correspond to the lifting mechanisms;
setting the fit of the support 3 with the socket 102 such that the leg of the patient 300 is in the first state;

In this embodiment, the first state may be a lying state of the patient 300; the second state may be a non-lying state, for example, when the lower limb of the patient 300 is raised to 30 °, 45 °, or 60 °. Of course, in other embodiments, the first state and the second state may not both be the lying state, for example, the first state is a state in which the lower limb of the patient 300 is raised to 30 ° and the second state is a state in which the lower limb of the patient 300 is raised to 60 °.
Since the general patient 300 has two lower limbs, i.e., left and right legs, the method for applying the magnetic resonance system scan described above, as shown in fig. 4, includes the following steps:

And then one preset angle or a plurality of preset angles of the left leg can be selected to be scanned according to the detection requirement. When a plurality of preset angles need to be scanned, the height of the left leg is readjusted to enable the left leg to be lifted to another preset angle, and the lumbosacral nerve of the patient 300 is scanned again by using the magnetic resonance coil 200.
After the left leg scan is completed, the left leg of the patient 300 is flattened, the right leg of the patient 300 is raised to a preset angle, and the lumbosacral nerve of the patient 300 is scanned again using the magnetic resonance coil 200. The multiple preset angles for scanning the right leg can also be selected according to the requirement, when the multiple preset angles are required to be scanned, the height of the right leg is readjusted to enable the right leg to be lifted to another preset angle, and the lumbosacral nerve of the patient 300 is scanned again by using the magnetic resonance coil 200.
After the single leg scanning is completed, the legs of the patient 300 can be scanned, at this time, the legs of the patient 300 are simultaneously lifted to a preset angle, and the lumbosacral nerve of the patient 300 is scanned again by using the magnetic resonance coil 200. The multiple preset angles of the two legs can be selected according to the requirement, when the multiple preset angles of the two legs need to be scanned, the heights of the two legs are readjusted, so that the two legs are lifted to another preset angle at the same time, and the lumbosacral nerve of the patient 300 is scanned again by using the magnetic resonance coil 200.
Through the multiple scans described above, image registration of the patient 300 in multiple different positions may be obtained to facilitate subsequent sequential lumbosacral nerve anatomy calibration, nerve length direction measurement, and nerve tension assessment/diagnosis.
