[0032] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model

[0033] As Figures 1 to 4 shown, a joint coil for magnetic resonance in an embodiment of the present utility model includes a coil body 1, a rotating mechanism 2, and a driving mechanism 3

[0034] As Figures 1 to 4 shown, the coil body 1 includes a coil housing 11, and a base 12 is installed at the bottom of the coil housing 11. A mounting boss 13 is integrally formed on the base 12, which facilitates magnetic resonance imaging of joints

[0035] As Figure 2 and Figure 3 shown, the coil housing 11 and the base 12 are fixed by a plurality of bolts, and the coil housing 11 is sleeved on the mounting boss 13

[0036] As Figures 3 to 6As shown in the figure, the rotating mechanism 2 includes a rotating plate 21. The rotating plate 21 is rotatably installed in the coil housing 11. By rotating the rotating plate 21 in the coil housing 11, the joint coil can adjust the detection angle according to the scanning requirements, so that the joint coil can observe the pathological changes of joints at different angles. Furthermore, the imaging effect of the lateral or oblique position lesions of the joints is better, improving the practicability of the joint coil. The lower end of the rotating plate 21 is installed on the mounting boss 13 by means of hinge, so that the rotating plate 21 can be adjusted in angle by rotation after installation. The upper end of the rotating plate 21 extends to a position close to the upper port of the coil housing 11. A driving shaft 22 is fixedly connected to the upper end of the rotating plate 21. The rotating plate 21 can be driven to rotate in the coil housing 11 through the driving shaft 22.

[0037] As Figure 6 shown, the rotating plate 21 is installed on the mounting boss 13 in a front-back arrangement, and the lower end of the rotating plate 21 is installed on one side away from the side port of the coil housing 11.

[0038] As Figure 6 Combined Figure 7 shown, a pair of first mounting seats 23 are fixedly connected to the mounting boss 13. Both ends of the lower end of the rotating plate 21 are fixedly connected with a pair of second mounting seats 24. A hinge shaft 25 is installed between the pair of first mounting seats 23 and the pair of second mounting seats 24. The first mounting seat 23 and the second mounting seat 24 are connected together through the hinge shaft 25. At the same time, the first mounting seat 23 can rotate on the second mounting seat 24 through the hinge shaft 25, enabling the rotating plate 21 to rotate after installation.

[0039] As Figures 1 to 5 shown, the driving mechanism 3 includes a mounting shell 31. The mounting shell 31 is installed on the upper port of the coil housing 11. An adjusting screw 32 is rotatably connected in the mounting shell 31. A driving block 33 is threadedly connected to the adjusting screw 32. The driving block 33 is installed in the mounting shell 31, so that the driving block 33 can be driven to move in the mounting shell 31 by rotating the adjusting screw 32. The lower end of the driving block 33 is sleeved on the driving shaft 22. By rotating the adjusting screw 32 to drive the driving block 33 to linearly move, the rotating plate 21 is further driven to rotate, realizing the angle adjustment of the rotating plate 21 in the coil housing 11. And the driving of the adjusting screw 32 makes it convenient to adjust the angle of the rotating plate 21 during scanning, improving the practicability of the joint coil. At the same time, when the adjusting screw 32 drives the driving block 33 to move by rotation, the rotating plate 21 can be driven to realize angle adjustment, so that the structure for driving the rotating plate 21 to adjust the angle is simple, making it convenient to adjust the angle of the rotating plate 21. And when the adjusting screw 32 is in a static state, the self-locking characteristic of the thread pair can keep the angle of the rotating plate 21 stable without an additional locking device.

[0040] AsFigure 8 As shown, a threaded hole 34 is provided on the driving block 33. The driving block 33 is threadedly connected to the adjusting screw 32 through the threaded hole 34, so that when the adjusting screw 32 rotates, the driving block 33 can be driven to move on the adjusting screw 32 under the action of the thread.

[0041] As Figure 5 and Figure 8 shown, an installation groove 35 is provided at the lower end of the driving block 33 in a front-to-back penetrating manner. The driving shaft 22 is sleeved in the installation groove 35. Since the driving shaft 22 is sleeved in the installation groove 35 at the lower end of the driving block 33, when the driving block 33 moves, the driving shaft 22 can be driven to move accordingly.

[0042] As Figure 5 and Figure 8 shown, a limiting sleeve 36 is fixedly connected to the inner side wall of the left side wall plate of the installation shell 31. The left end of the adjusting screw 32 is rotatably connected to the limiting sleeve 36. Through the limiting sleeve 36, while one end of the adjusting screw 32 is stably installed, it can rotate normally.

[0043] As Figure 5 and Figure 8 shown, an installation hole 37 is provided on the right side wall plate of the installation shell 31 in a penetrating manner. The adjusting screw 32 is rotatably connected to the installation hole 37 in a penetrating manner, so that when the adjusting screw 32 is installed, the threaded end passes through the installation hole 37 and is sleeved in the limiting sleeve 36.

[0044] As Figure 2 and Figure 8 shown, a pair of installation plates 39 are integrally formed at the left and right ends of the installation shell 31. Fixing screws 310 are threadedly connected between the pair of installation plates 39 and the left and right end wall plates of the upper port of the coil housing 11. Through the fixing screws 310, the installation plates 39 can be fixed to the upper port of the coil housing 11, thereby stably installing the installation shell 31 on the coil housing 11.

[0045] As Figure 5 and Figure 8 shown, a guide plate 38 is installed on the right side wall plate of the upper port of the coil housing 11. The adjusting screw 32 is rotatably connected to the guide plate 38. The guide plate 38 is used to guide the installation of the adjusting screw 32, making the installation of the adjusting screw 32 convenient. A driving head 311 is fixedly connected to the right end of the adjusting screw 32. By rotating the driving head 311, the adjusting screw 32 can be driven to rotate.

[0046] In use, the coil housing 11 is installed on the joint of the patient and fixed. During magnetic resonance examination, imaging of the joint area can be performed through the joint coil. When it is necessary to observe joint lesions at different angles and lateral or oblique lesions of the joint, by rotating the adjusting screw 32, the rotation of the adjusting screw 32 can drive the driving block 33 to move within the mounting housing 31. When the driving block 33 moves, it will drive the driving shaft 22 to move. The movement of the driving shaft 22 causes the rotating plate 21 to rotate, thereby realizing the adjustment of the detection angle and achieving the scanning and exploration of joint lesions at different angles and lateral or oblique lesions of the joint; and the adjustment of the angle of the rotating plate 21 can be realized by rotating the adjusting screw 32, making the structure for adjusting the angle of the rotating plate 21 simple and convenient for fixing the angle of the rotating plate 21 after adjustment.
