Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary nuclear magnetic resonance head and neck coils, in particular to an adjustable-angle auxiliary nuclear magnetic resonance head and neck coil variable device. Background Art

[0002] The main functions of the adjustable-angle auxiliary nuclear magnetic resonance head and neck coil variable device are to improve the quality of magnetic resonance imaging, increase the inspection efficiency, and enhance the patient comfort. Specifically, it can adapt to the sizes and shapes of the head and neck of different patients, enabling the coil to fit more closely to the patient's head and neck, thereby improving the efficiency and uniformity of signal reception and obtaining clearer and more accurate images; it can quickly locate and fix, reducing the placement time and adjustment times of the patient on the examination bed; it can also relieve the pressure of the coil on the patient's head and neck, reducing discomfort, and can better adapt to patients with special body position requirements (such as: patients with Hirayama disease undergoing magnetic resonance imaging of the cervical spine in the overflexion position).

[0003] The traditional adjustable-angle auxiliary nuclear magnetic resonance head and neck coil variable device generally consists of the following mechanisms: a device main frame for providing overall support and structural stability; an angle adjustment mechanism, commonly such as a gear-rack transmission, a hinge connection combined with an adjustment bolt, etc., which can realize the angle change of the coil to meet the examination needs of different patients; a fixing and locking mechanism for fixing the coil at a specific position after adjusting the angle to prevent movement or angle change during the examination; a sliding mechanism enabling the coil to slide within a certain range for further precise positioning; and a connection and support mechanism for connecting each component together and providing support for the coil to ensure the reliability and stability of the coil during use.

[0004] However, for the traditional angle-assisted nuclear magnetic resonance head and neck coil variable device, the structure of its angle adjustment mechanism is relatively simple, which is not convenient for quickly and easily adjusting the head of patients who cannot lie flat due to anterior flexion of the vertebral body, and will also affect the patient comfort while reducing the examination quality. Therefore, an adjustable-angle auxiliary nuclear magnetic resonance head and neck coil variable device is proposed to solve the above problems. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides an adjustable-angle auxiliary nuclear magnetic resonance head and neck coil variable device, aiming to improve the problem in the prior art that the head angle of patients cannot be quickly adjusted, which affects the patient comfort and reduces the detection efficiency at the same time.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the present utility model, when the handle is rotated, the handle drives the nut on the outer wall to rotate under force.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1 - 3, an embodiment provided by the present utility model: an adjustable-angle auxiliary nuclear magnetic resonance head and neck coil variable device, including a support plate 2. A first connecting block 3 is fixedly connected to the top of the support plate 2. A first pin shaft 4 is rotatably connected inside the first connecting block 3. A base 1 is rotatably connected to the outer wall of the first connecting block 3. A second connecting block 5 is fixedly connected to the side wall of the base 1. A second pin shaft 7 is rotatably connected inside the second connecting block 5. A first fixing block 6 is rotatably connected to the outer wall of the second pin shaft 7. A first hollow plate 8 is fixedly connected to the bottom of the first fixing block 6. A third pin shaft 9 is rotatably connected inside the first hollow plate 8. A connecting component is arranged on the outer wall of the third pin shaft 9. The connecting component is used for connecting the first hollow plate 8 and the second hollow block 12. The connecting component includes a first support arm 10. The first support arm 10 is rotatably connected to the outer wall of the third pin shaft 9 inside. A fourth pin shaft 11 is rotatably connected inside the first support arm 10. A second hollow block 12 is rotatably connected to the outer wall of the fourth pin shaft 11. A nut 13 is fixedly connected to the inner wall of the second hollow block 12. A threaded rod 19 is threadedly connected inside the nut 13. A fifth pin shaft 14 is rotatably connected inside the second hollow block 12. A second support arm 15 is rotatably connected to the outer wall of the fifth pin shaft 14. The second support arm 15 is rotatably connected to a sixth pin shaft 16 inside. One end of the threaded rod 19 is fixedly connected to a handle 18. A second hollow plate 17 is rotatably connected to the outer wall of the sixth pin shaft 16. The bottom of the second hollow plate 17 is fixedly connected to the top of the support plate 2.

[0029] Specifically, when using the adjustable-angle auxiliary nuclear magnetic resonance head and neck coil variable device, first, by rotating the handle 18, at this time, the external force received by the handle 18 will cause the threaded rod 19 to drive and rotate. When the threaded rod 19 starts to rotate, it will drive the nut 13 on its outer wall, so that the nut 13 moves on the outer wall of the threaded rod 19. And it should be noted that the second hollow blocks 12 are fixed on both sides of the nut 13. At the same time, when the nut 13 is subjected to an external force, it will drive the first support arm 10 to rotate, and the first support arm 10 is connected to the second hollow block 12 through the fourth pin shaft 11. Next, when the first support arm 10 is subjected to an external force, it will drive the first hollow plate 8 on its outer wall to move, and the third pin shaft 9 inside the first hollow plate 8 is used to connect with the first support arm 10. Next, during the rotation of the nut 13, it will drive the second support arm 15 to rotate together. At the same time, the fifth pin shaft 14 is used to connect the second hollow block 12 and the second support arm 15. Next, the second support arm 15 will rotate inside the second hollow plate 17. To sum up, when the first hollow plate 8 is subjected to an external force, it will drive the first fixing block 6 on the top to rotate. At the same time, the rotation of the first fixing block 6 will drive the second connecting block 5 on its outer wall to rotate. After the second connecting block 5 is subjected to an external force, it will drive the base 1 to rotate, and finally achieve the effect of adjustable angle.

[0030] Working principle: When using the adjustable-angle assisted nuclear magnetic resonance head and neck coil variable device, first, by rotating the handle 18, the force on the handle 18 drives the threaded rod 19 to rotate. When the threaded rod 19 rotates, it drives the nut 13 on its outer wall to move on the outer wall of the threaded rod 19. Both sides of the nut 13 are fixed with second hollow blocks 12. At the same time, under the force of the nut 13, the first support arm 10 is driven to rotate. The first support arm 10 is connected to the second hollow block 12 through the fourth pin 11. Next, under the force of the first support arm 10, the first hollow plate 8 on its outer wall is driven to move. The third pin 9 inside the first hollow plate 8 is used to connect to the first support arm 10. Next, when the nut 13 rotates, the second support arm 15 is also driven to rotate. At the same time, the fifth pin 14 is used to connect the second hollow block 12 and the second support arm 15. Next, the second support arm 15 rotates inside the second hollow plate 17. To sum up, when the first hollow plate 8 is under force, the first fixing block 6 at the top is driven to rotate. At the same time, the rotation of the first fixing block 6 drives the second connecting block 5 on its outer wall to rotate. The force on the second connecting block 5 drives the base 1 to rotate, achieving the effect of adjustable angle.
