Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a magnetic resonance scanning head fixing frame. Background Art

[0002] Magnetic resonance imaging (MRI) is a non-invasive medical imaging technique used to obtain detailed images of a patient's internal structures. It utilizes powerful magnetic fields and radio waves to generate images, eliminating the need for X-rays. It is commonly used to examine the brain, spine, joints, and internal organs. However, most existing pillows used by patients during MRI examinations are conventional. This can easily lead to unstable head fixation, causing shaking during the examination, which can distort the MRI images and affect image quality. In light of this, the present invention proposes a head fixation frame for MRI scanning to address the aforementioned technical issues. Utility Model Content

[0003] In order to overcome the shortcomings of the existing MRI scanning head fixation frame, in which most of the pillows used by patients are ordinary pillows, which easily lead to unstable fixation of the patient's head and shaking during the examination, thereby distorting the image formed by the MRI and affecting the image quality, the utility model provides an MRI scanning head fixation frame.

[0005] The first fixing assembly includes first fixing blocks slidably connected to both sides of the base, soft bodies are fixed to the opposite surfaces of the two first fixing blocks, a sliding rod is fixed to the bottom surface of the base, the first fixing block is slidably connected to the sliding rod, a first connecting spring is provided between the first fixing block and the sliding rod, and both ends of the first connecting spring are respectively fixed to the first fixing block and the sliding rod.

[0006] Furthermore, the first fixing assembly also includes a third fixing block fixedly connected to the bottom surface of the base, the third fixing block is rotatably connected to the winding wheel, a pull rope is provided below the base, a guide block is fixedly connected below the slide rod, both ends of the pull rope are respectively coiled on the guide blocks and pass through the lower part of the slide rod, and are finally fixed on the side surfaces of the two first fixing blocks that are away from each other, and the middle part of the pull rope is coiled on the winding wheel.

[0007] Furthermore, a rocker is fixedly connected to one side surface of the winding wheel.

[0008] Furthermore, the protective component includes a connecting frame slidably connected to the inside of the first fixed block, and the first sponge block is fixed to the opposite surfaces of the two connecting frames. The connecting frame passes through the interior of the soft body, and two second connecting springs are provided between the connecting frame and the first sponge block. The two ends of the second connecting springs are respectively fixed to the connecting frame and the first sponge block.

[0009] Furthermore, the first sponge block is provided with a through hole for placing the patient's ear.

[0012] Furthermore, a spiral spring is provided at the connection between the first connecting block and the second fixing block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The present invention is provided with a first fixing assembly. When in use, the patient places his head on the headrest, and then the medical staff rotates the rocker to loosen the pull rope, thereby resetting the first connecting spring, and then the two first fixing blocks approach each other, thereby clamping the patient's head. This can reduce motion artifacts, make MRI images clearer and more accurate, and thus improve the reliability of diagnosis.

[0015] 2. The utility model is provided with a protective component. When the first fixing block moves to clamp the patient's head, the first sponge block first contacts the patient's head, and then the first sponge block remains stationary relative to the patient's head, while the first fixing block continues to move on the first connecting spring, and then the first sponge block is stuck in the interior of the soft body, thereby forming a closed soundproof space, which can isolate the noise generated by magnetic resonance during detection and reduce the risk of hearing damage.

[0016] 3. The utility model is provided with a second fixing component. When the first sponge block is stationary relative to the patient's head, and the first fixing blocks are close to each other relative to the patient's head, the connecting frame and the first connecting block contact each other, thereby causing the first connecting block to rotate toward the patient's head, and then the second sponge block contacts the patient's forehead to fix the patient's forehead, preventing the head from moving or rotating slightly during the MRI scan, thereby improving the cleanliness and accuracy of the image.
