Description

Technical Field

[0001] This utility model relates to the field of magnetic resonance imaging system technology, specifically to a hand coil with an indicating function. Background Technology

[0002] Magnetic resonance imaging (MRI) is a medical application of the principles of magnetic resonance imaging. Compared with other auxiliary examination methods, MRI has advantages such as more imaging parameters, faster scanning speed, higher tissue resolution, and clearer images.

[0003] During MRI scans, patients need to wear appropriate external coils around the areas being examined for imaging. Common external coils include head coils, hand coils, knee coils, ankle coils, and shoulder coils. Hand coils are used to examine the patient's hand, typically for the wrist, palm, and fingers. When examining different parts of the hand, the patient inserts their hand into different sections of the coil so that images can be captured by different coil units within the coil. Current hand coils lack indicator structures, making it unclear to patients where to place their hand on the coil for the specific area being examined. Therefore, doctors must repeatedly explain the correct placement, and even with repeated explanations, patients often struggle to position their hand correctly, affecting the accuracy of the results. Thus, current hand coils are cumbersome to use, and the accuracy of examination results for various areas needs improvement. Utility Model Content

[0022] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0023] 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.

[0024] like Figure 1-4As shown, a hand coil with an indicating function includes a base 1 and a coil assembly, which is detachably connected to the base 1. The coil assembly includes a first housing 2 and a second housing 3. One end of the first housing 2 is hinged to one end of the second housing 3, and the first housing 2 can be rotated and swung along the junction, thereby allowing the first housing 2 to be flipped open relative to the second housing 3. The first housing 2 is provided with a locking device, and the second housing 3 is provided with a locking hole 31. The locking device is detachably engaged with the locking hole 31. The first housing 2 and the second housing 3 together form a receiving cavity 4 for placing the hand. During examination, by operating the locking device, it can be disengaged from the locking hole 31, thereby pulling the first housing 2 to flip open relative to the second housing 3 so that the patient can place their hand into the receiving cavity 4; then, the first housing 2 can be closed onto the second housing 3, so that the receiving cavity 4 surrounds the patient's hand for examination.

[0025] Indicator structures 5 are provided on the outer walls of the first housing 2 and the second housing 3. Coil units are respectively provided in the first housing 2 and the second housing 3 at corresponding positions to the indicator structures 5. The indicator structure 5 includes a wrist indicator 51, a palm indicator 52, and a finger indicator 53. When using this hand coil with indicator function to examine a patient, the first housing 2 can be opened by operating the locking device along the hinge end. Then, the patient can observe the indicator structure 5 and place the corresponding position of the hand into the corresponding indicator structure 5. After that, the first housing 2 is closed onto the second housing 3, so that the locking device is locked with the locking hole 31. Then, magnetic resonance imaging examination of the corresponding position of the hand can be performed through the coil unit. Specifically: when examining the palm, the patient can insert the palm into the receiving cavity 4 at the position corresponding to the palm indicator 52; when examining the wrist, the patient can insert the wrist into the receiving cavity 4 at the position corresponding to the wrist indicator 51; when examining the fingers, the patient can insert the fingers into the receiving cavity 4 at the position corresponding to the finger indicator 53.

[0026] This hand coil with indicator function, by setting wrist indicator 51, palm indicator 52 and finger indicator 53 respectively, enables the patient to quickly place the part of the hand to be examined, thereby simplifying the operation and improving the efficiency and accuracy of the examination.

[0027] The second housing 3 has a connecting post 32 on its side wall, and the base 1 has a limiting groove 11. The connecting post 32 passes through the limiting groove 11 and is slidably engaged with it. The connecting post 32 and the base 1 are slidably connected, so the second housing 3 can be pushed to slide on the base 1, thereby changing its installation position on the base 1 to accommodate the examination needs of both the left and right hands. During the examination, the patient can lie flat on the base 1 and then insert their hand into the receiving cavity 4 between the first housing 2 and the second housing 3 to perform the examination.

[0028] In this embodiment, there are two limiting slide grooves 11, and the two limiting slide grooves 11 are arranged parallel to each other on the base 1. By setting two slide grooves, the second housing 3 and the base 1 can be limited at two positions, improving the stability of their connection. At the same time, the two limiting slide grooves 11 can also limit and guide the sliding direction of the second housing 3 on the base 1. In other embodiments, the number of limiting slide grooves 11 can be any other number.

[0029] To facilitate installation, a clearance slot 12 adapted to the connecting post 32 is provided on the side wall of the limiting slide groove 11. During the process of installing the second housing 3 onto the base 1, the connecting post 32 can be aligned with the clearance slot 12 first, so that the connecting post 32 passes through the clearance slot 12. Then, the second housing 3 can be pushed so that the connecting post 32 engages with the limiting slide groove 11, thereby limiting the installation of the second housing 3 onto the base 1.

[0030] In actual examinations, in some cases the patient needs to place their hand flat inside the hand coil, while in others the patient needs to place their hand upright inside the hand coil for examination. To meet these usage requirements, in this embodiment, connecting posts 32 are respectively provided on the lower end face and the left and right side end faces of the second housing 3. By providing connecting posts 32 on the lower end face and the left and right side end faces of the second housing 3, the second housing 3 can be installed flat on the base 1 or upright on the base 1, thereby meeting diverse examination needs and improving versatility.

[0031] To meet the above usage requirements, indicator structures 5 are respectively provided on the upper end face and left and right end faces of the first housing 2, and on the left and right end faces of the second housing 3. This allows patients to see the corresponding indicator structures 5 during examination, whether the second housing 3 is installed lying down or upright, thus meeting diverse usage needs and improving the accuracy of the examination.

[0032] In this embodiment, the indicator structure 5 is an indicator mark, that is, a graphic indicator mark drawn on the first housing 2 and the second housing 3 by a tool; in other embodiments, the indicator structure 5 may also be an indicator sticker pasted on the surface of the first housing 2 and the second housing 3 or other devices that can perform the function of indicating.

[0033] The locking device includes an unlocking switch 6 and a linkage rod 7. The unlocking switch 6 and the linkage rod 7 are slidably connected to the first housing 2. One end of the linkage rod 7 is connected to the unlocking switch 6, and the other end is provided with a locking tongue 71. The locking tongue 71 is aligned with the locking hole 31. The unlocking switch 6 can push the linkage rod 7 to move, thereby causing the locking tongue 71 to engage or disengage from the locking hole 31. Normally, when the first housing 2 and the second housing 3 are closed, the locking tongue 71 extends into the locking hole 31, thereby fixing the first housing 2 and the second housing 3 in place. When it is necessary to open the first housing 2, the unlocking switch 6 can be pushed. The unlocking switch 6 will push the linkage rod 7 to move, and the linkage rod 7 will move the locking tongue 71, causing the locking tongue 71 to disengage from the locking hole 31. At this time, the first housing 2 can be pulled upward to open it by flipping it upward along the hinge end.

[0034] A spring is installed on the first housing 2. When the user operates the unlock switch 6 to push the linkage rod 7, the linkage rod 7 compresses the spring. When the user releases the unlock switch 6, the spring pushes the linkage rod 7 to move in the opposite direction, thereby causing the latch 71 to return to its original position and extend. During the process of closing the first housing 2 onto the second housing 3, the side wall of the second housing 3 will press the latch 71, causing it to push the linkage rod 7 back into the first housing 2, and the linkage rod 7 will compress the spring. When the latch 71 is aligned with the locking hole 31, the spring force will push the linkage rod 7 to extend, thereby causing the latch 71 to extend into the locking hole 31, thus connecting and fixing the first housing 2 and the second housing 3.

[0035] To facilitate operation, an unlocking indicator 8 is provided on the first housing 2 at a position corresponding to the unlocking switch 6. By observing the unlocking indicator 8, the user can determine in which direction to pull the unlocking switch 6 to unlock the first housing 2 and the second housing 3; the unlocking indicator 8 improves the convenience and efficiency of operation.

[0036] To facilitate movement and handling, handle slots 13 are provided at both ends of the base 1; users can place or move the hand coil with indicator function to the preset position by holding the handle slots 13, which improves practicality.

[0037] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
