Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy equipment, and more specifically, to a support device for radiotherapy equipment and an examination bed thereof. Background Art

[0002] Magnetic resonance radiotherapy is radiotherapy guided by magnetic resonance images. Magnetic resonance imaging can achieve soft tissue imaging, enabling accurate delineation of the treatment target area and accurate diagnosis of diseases. Clinically, when performing magnetic resonance examination on a patient's head, in order to achieve postural consistency, radiotherapy equipment such as a magnetic resonance flexible coil is needed to cover the patient's head and perform scanning. Since the magnetic resonance scanning time is relatively long, and the weight of the magnetic resonance flexible coil itself will cause obvious pressure on the patient's head, it is easy to make the patient have difficulty breathing, resulting in the patient being unable to maintain a relatively static posture for a long time during the scanning process, which will have a certain impact on the imaging accuracy, and even some patients cannot persist in completing the examination.

[0003] At present, although there are support devices that can be used to support radiotherapy equipment such as magnetic resonance flexible coils, the existing support devices only have a relatively single support method, and the support devices are unstable, and there is still a risk of displacement of the support device during scanning, and there is still a hidden danger of affecting the imaging accuracy.

The L-shaped structure or the V-shaped-like structure enables the support structure 1 to be applicable to the support of nuclear magnetic resonance flexible coils of different specifications or models.

[0036] As Figures 1 to 4As shown, the first-direction adjustment mechanism 2 includes an adjustment plate 21 and a plurality of first sliding grooves 211 provided on the adjustment plate 21. A first slider 16 is connected to the second surface of the connection plate 11, and the first slider 16 is slidably engaged in the first sliding groove 211.

Specifically, the second alignment concave part can be a second arc-shaped concave part, and the alignment convex part is an arc-shaped convex part, and the arc-shaped convex part is adapted to the second arc-shaped concave part. It should be noted that the second alignment part 221 can also be set as a convex structure, and the third alignment part 321 is set as a concave structure adapted to the convex structure.

[0042] As Figure 2 shown in the figure, in order to facilitate the horizontal adjustment of the adjusting plate 21, a positioning mark 214 corresponding to the second alignment part 221 one by one is provided at one end of the adjusting plate 21 close to the second slider 22 on the plate surface. A corresponding alignment mark 313 is provided on the outer surface of the mounting seat 31 at the position corresponding to the third alignment part 321. When the adjusting plate 21 slides to make the alignment mark 313 correspond to any positioning mark 214, at this time, the third alignment part 321 corresponds to the corresponding second alignment part 221. Then, the alignment block 32 can be slid downward to make the third alignment part 321 match and clamp with the second alignment part 221 to complete the locking, as Figure 6 shown in the figure; and when the horizontal position of the adjusting plate 21 needs to be adjusted, the alignment block 32 is slid upward, and the third alignment part 321 is misaligned with the second alignment part 221 to achieve unlocking, as Figure 7 shown in the figure.

[0043] As Figure 1 and Figure 2As shown in the figure, the connecting member 4 includes a plurality of positioning pins connected to the second-direction adjusting mechanism 3.

The radiotherapy device support device is detachably connected to the detection bed 5 through the connecting member 4. In this embodiment, a plurality of insertion holes 51 are provided at the head end of the detection bed 5. The overlap between the detection bed 5 and the radiotherapy device support device is realized by inserting the positioning pins into the insertion holes 51. To make the distance between the two radiotherapy device support devices on the detection bed 5 adjustable, a plurality of insertion holes 51 can be arranged along the width direction on the detection bed 5, as Figure 9 shown in the figure.

[0048] A method for using a radiotherapy device support device of the present utility model is as follows:

[0049] According to the specifications of the nuclear magnetic flexible coil to be used, place the connectors 4 on the two radiotherapy equipment support devices at the corresponding insertion holes 51 as required to complete the connection between the radiotherapy equipment support device and the detection bed 5; when the support height needs to be adjusted, loosen the locking member 23, and the support structure 1 can slide along the first sliding groove 211. When the support structure 1 is at the appropriate height position, tighten the locking member 23 and align the locking member 23 with the first alignment portion 213, which can facilitate the corresponding adjustment of the radiotherapy equipment support device on the other side to obtain the same height position; when the distance between the edge positions of the head of the bed needs to be adjusted, slide the alignment block 32 upward. At this time, the adjustment plate 21 can slide along the second sliding groove 311 to make the adjustment plate 21 at the appropriate distance position and align the positioning mark 214 with the alignment mark 313, and then slide the alignment block 32 downward to complete the locking. The radiotherapy equipment support device on the other side can be adjusted corresponding to the corresponding mark position to obtain the same distance position; after the adjustment is completed, place the nuclear magnetic flexible coil at the support structure 1. The support member 12 can support both ends of the nuclear magnetic flexible coil, and the first limiting member 13 and the second limiting member 14 can prevent the nuclear magnetic flexible coil from shifting.
