[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figures 2-6 As shown, a supine shoulder joint coil device suitable for different groups of people includes a base 1 and a coil assembly 2. The coil assembly 2 is slidably and limitedly connected to the base 1. The installation position of the coil assembly 2 on the base 1 can be adjusted by moving the coil assembly 2 to slide on the base 1, so as to meet the usage needs of patients of different body sizes and improve versatility.
[0028] Specifically, the coil assembly 2 includes a contoured housing 21, within which multiple coil units are housed. These coil units are connected to an external controller via a circuit board. The contoured housing 21 also includes a placement slot 22 adapted to the human shoulder. During examination, the patient lies flat on the base 1 and inserts their shoulder into the placement slot 22. The coil units acquire graphic information of the patient's shoulder, which is then fed back to the magnetic resonance imaging system via the circuit board, thus enabling the examination of the patient's shoulder joint. Connecting seats 3 are located on the outer walls at both ends of the contoured housing 21, connecting to the base 1. By providing connecting seats 3 at both ends of the contoured housing 21, this supine shoulder joint coil device can be used to examine both the user's left shoulder and the patient's right shoulder. When switching is required, simply flip the contoured housing 21 so that the connecting seat 3 on the other side connects to the base 1, thereby changing the orientation of the placement slot 22 to suit either the left or right shoulder.
[0029] The base 1 is provided with a guide sliding groove 11, one end of the connecting seat 3 passes through the guide sliding groove 11, and the connecting seat 3 is in sliding connection with the guide sliding groove 11. The base 1 is provided with a limiting block 4 and a reset assembly. One end of the connecting seat 3 extending into the guide sliding groove 11 can slide on the limiting block 4. The limiting block 4 is connected with the reset assembly, and the reset assembly is used to push the limiting block 4 to abut against the connecting seat 3. Under normal circumstances, the connecting seat 3 abuts against the limiting block 4, so that the profiling shell 21 is connected and fixed with the base 1, thereby facilitating the examination of the shoulder joint of the patient. When the position of the coil assembly 2 needs to be adjusted, the profiling shell 21 can be pushed or pulled, so that the connecting seat 3 slides in the guide sliding groove 11 and slides on the limiting block 4. After being adjusted to a suitable position, the profiling shell 21 is released and pushed to abut against the connecting seat 3 by the reset assembly, so that the profiling shell 21 is limited and fixed with the base 1.
[0030] The lying type shoulder joint coil device applicable to different people can adjust the installation position of the coil assembly 2 on the base 1 by moving the profiling shell 21, so that it can be used by patients with different body shapes, improving the universality. According to the different body shapes of patients, the position of the coil assembly 2 on the base 1 can be adjusted in advance, so that the patient does not need to move the body during examination, improving the comfort of patient examination.
[0031] The reset assembly includes a reset spring 5. The reset spring 5 is installed on the base 1. One end of the limiting block 4 is provided with a mounting column 41. One end of the reset spring 5 away from the base 1 is sleeved on the mounting column 41 and fixedly connected with the limiting block 4. During the process of pushing or pulling the profiling shell 21, the connecting seat 3 slides in the guide sliding groove 11 and presses the limiting block 4, so as to compress the reset spring 5 through the limiting block 4. After being adjusted to a suitable position, the limiting block 4 is pushed to move towards the connecting seat 3 under the elastic force of the reset spring 5, so that the limiting block 4 is connected and fixed with the connecting seat 3.
[0032] In the embodiment, the limiting block 4 is in sliding limiting connection with the base 1. The number of the limiting block 4 is two, and each limiting block 4 is provided with two mounting columns 41. The reset spring 5 is correspondingly arranged with the mounting column 41. By arranging two reset springs 5 on the limiting block 4, the limiting block 4 and the connecting seat 3 can be more stably pushed to abut against each other, improving the stability of transmission and structure. By arranging two limiting blocks 4, the lying type shoulder joint coil device can be simultaneously applicable to the examination requirements of the left shoulder and the right shoulder.
[0033] In order to enable the limiting block 4 to be connected and fixed with the connecting seat 3, a plurality of gear grooves 42 are distributed on the side wall of the limiting block 4 at equal intervals, close to one end of the connecting seat 3, and the reset spring 5 can push the gear groove 42 to limit the clamping of the connecting seat 3. In the process of moving the profiled shell 21, the connecting seat 3 will slide on the limiting block 4, and the limiting block 4 will compress the reset spring 5; and the connecting seat 3 is aligned with each gear groove 42 in turn; after adjusting to the appropriate position, the profiled shell 21 is released, and under the elastic force of the reset spring 5, the limiting block 4 will be pushed to move towards the connecting seat 3, so that the gear groove 42 aligned with the connecting seat 3 is clamped and fixed with the connecting seat 3, thereby completing the adjustment process of the coil assembly 2. By providing a plurality of gear grooves 42 on the limiting block 4, the connecting seat 3 will jump in each gear groove 42 during the process of pushing the profiled shell 21, thereby emitting a "click" sound; medical staff can determine whether the gear groove 42 is aligned with the connecting seat 3 through hearing and tactile feeling, thereby improving the convenience of adjustment.
[0034] In order to limit the position of the limiting block 4 in the base 1, a limiting table 12 is provided on the base 1, and limiting steps 43 are provided at both ends of the limiting block 4, and the reset spring 5 can push the limiting steps 43 to abut against the limiting table 12. Under normal circumstances, the connecting seat 3 is clamped with the gear groove 42, and at this time the limiting steps 43 also abut against the limiting table 12; in the process of moving the profiled shell 21, the connecting seat 3 slides on the limiting block 4, which pushes the limiting steps 43 away from the limiting table 12, so that the limiting block 4 compresses the reset spring 5. When moving to the appropriate position, the gear groove 42 on the limiting block 4 will be clamped with the connecting seat 3 under the elastic force of the reset spring 5; after the gear groove 42 is clamped with the connecting seat 3, the limiting steps 43 also abut against the limiting table 12. The cooperation of the limiting table 12 and the limiting steps 43 can limit the movement position of the limiting block 4, avoid the limiting block 4 from falling out of the base 1, and improve the stability of the structure and the accuracy of transmission.
[0035] In the embodiment, the connecting seat 3 includes a sliding block 31 and a clamping block 32, the sliding block 31 is fixedly connected with the clamping block 32 and the profiled shell 21 respectively, the sliding block 31 is in sliding cooperation with the guide sliding groove 11, and the clamping block 32 is slidably clamped with the limiting block 4.
[0036] In order to facilitate the installation of the connecting seat 3, the side wall of the guide sliding groove 11 is provided with a size-fitting avoiding gap 13 through which the clamping block 32 can pass; in the installation of the coil assembly 2, the clamping block 32 is passed through the avoiding gap 13, and then the profiled shell 21 is pushed to make the sliding block 31 slide into the guide sliding groove 11, and the clamping block 32 is clamped and limited with the base 1, so that the connecting seat 3 is clamped and limited with the base 1 as a whole; then the profiled shell 21 is pushed to make the clamping block 32 clamped and fixed with the limiting block 4, so as to limit and fix the profiled shell 21 on the base 1, and improve the stability of the structure.
[0037] In order to facilitate the operation, the profiled shell 21 is provided with a handle 6 on the side wall, and the user holds the handle 6 to facilitate the pushing or pulling of the profiled shell 21 to slide in the guide sliding groove 11, thereby improving the convenience of operation.
[0038] The lower end surface of the base 1 is provided with a mounting block 7 which is detachably connected with the base 1 by screws. The mounting block 7 can be used to mount the flat lying shoulder joint coil device on the imaging equipment of the magnetic resonance imaging system; the detachable connection of the mounting block 7 with the base 1 is used to adapt to different magnetic resonance imaging systems; in the specific operation process, the mounting block 7 which is adapted to the magnetic resonance imaging system can be replaced, so as to mount the flat lying shoulder joint coil device on the imaging equipment of the magnetic resonance imaging system.
