Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to a special shoulder and back fixation device for examining patients with scoliosis. Background Technology

[0002] X-rays are a type of ray, commonly known as X-rays. They are a type of electromagnetic wave or radiation with energy. X-rays can be generated when high-speed electrons collide with matter of any form. X-rays are penetrating and have different penetrating abilities to matter of different densities. In medicine, X-rays are used to project images of the human body to aid in diagnosis or to irradiate lesions for treatment.

[0003] During X-ray imaging, patients need to remain still in one position; otherwise, motion artifacts can easily appear in the final image, affecting the final image quality and even the doctor's judgment of the patient's condition. Most patients can complete the X-ray smoothly, but for scoliosis patients, especially those with severe scoliosis, whose condition has already affected their ability to stand and walk, motion artifacts are more likely to appear in the imaging stage. Therefore, a special shoulder and back fixation device for scoliosis patients is needed to support the upper limbs and increase their stability during the examination. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-Figure 5 The specific embodiments of this utility model will be described in further detail.

[0025] Depend on Figure 1-Figure 5 The present invention includes a first support rod 1 and two second support rods 2. In order to provide appropriate upper limb support for patients with scoliosis during examination, a rotating sleeve 3 is rotatably connected to the middle of the first support rod 1. The left and right sides of the rotating sleeve 3 are respectively fixedly connected to the corresponding second support rods 2. A limiting mechanism 4 is provided inside the rotating sleeve 3. A support plate 5 is provided on the upper side of the first support rod 1. Two support frames 6 that can move back and forth are provided inside the support plate 5. A support mechanism 7 is provided on the lower side of the first support rod 1 and each of the second support rods 2.

[0026] In use, the first support rod 1 can be rotated relative to the two second support rods 2 to unfold the device. At this time, the support plate 5 will change from a vertical state to a horizontal state, and the device can be moved to a suitable position to support the patient's limb. After moving to a suitable position, the first support rod 1 can be rotated in the opposite direction relative to the second support rod 2. At this time, each support mechanism 7 will change its contact position with the ground, so that the device as a whole is fixed, which can provide more stable support for the patient's limb. In use, the relative angle between the first support rod 1 and the second support rod 2 can be fixed by the limiting mechanism 4.

[0027] Furthermore, by Figure 1-Figure 5To facilitate the adjustment and storage of the device by the staff, the limiting mechanism 4 includes a threaded rod 8 that is threadedly connected to the rotating sleeve 3. An adjustment knob 9 is fixedly connected to the left side of the threaded rod 8, and a conical frustum 10 is fixedly connected to the middle of the threaded rod 8. The threaded rod 8 has two adjusting threads 11 in the same direction, which are located on the left and right sides of the conical frustum 10, respectively. The threaded rod 8 is threadedly connected to the rotating sleeve 3 through the adjusting threads 11. The middle of the rotating sleeve 3 is provided with multiple limiting blocks 12 that can move radially along the rotating sleeve 3 at the position corresponding to the position of the conical frustum 10. The rotating sleeve 3 has a limiting groove radially provided at the position corresponding to each limiting block 12, which allows the limiting block 12 to slide relative to the rotating sleeve 3. The side of each limiting block 12 near the conical frustum 10 is slidably connected to the conical frustum 10.

[0028] In use, medical staff can directly limit the distance between the first support rod 1 and the second support rod 2 by rotating the adjustment knob 9. Specifically, when it is necessary to limit the distance between the first support rod 1 and the second support rod 2, the adjustment knob 9 can be rotated clockwise. At this time, under the action of each adjustment thread 11, the adjustment knob 9 and the threaded rod 8 will move to the right relative to the rotating sleeve 3, thereby causing the conical frustum 10 to move to the right. Since the inclined surface 19 of the conical frustum 10 is set to the right, during the process of the conical frustum 10 moving to the right, it will squeeze the inner side of the limiting block 12, so that its outer side contacts the first support rod 1. Through the action of friction, the first support rod 1 cannot rotate relative to the rotating sleeve 3, thus completing the relative fixation between the first support rod 1 and the second support rod 2. At this time, under the self-locking action of the thread, the adjustment knob 9 will not rotate on its own. When it is necessary to contact the distance between the first support rod 1 and the second support rod 2, it is only necessary to rotate the adjustment knob 9 in the opposite direction.

[0029] Furthermore, by Figure 1-Figure 5 As shown, in order to facilitate the storage of the device, a connecting block 13 is rotatably connected to the upper side of the first support rod 1 and each second support rod 2, and three connecting slots 14 are opened on the lower side of the support plate 5, and each connecting block 13 is slidably connected to the corresponding connecting slot 14.

[0030] When in use, the support plate 5 is in a vertically stored state. When the device needs to be used, the support plate 5 can be rotated to a horizontal state. Then, when the first support rod 1 and the second support rod 2 rotate relative to each other, the connecting block 13 on the upper side of the first support rod 1 and the support block on the upper side of the second support rod 2 will move away from each other and abut against the front and rear side walls of the connecting groove 14 respectively, so that the support plate 5 will not slide relative to the connecting block 13.

[0031] Furthermore, by Figure 1-Figure 4To make the device more stable when placed, a fixing buckle 15 that is compatible with the second support rod 2 is fixedly connected to both the front and rear sides of the lower part of the support plate 5.

[0032] When in use, the fixing buckle 15 can cooperate with the two second support rods 2, thereby limiting the support plate 5 when the device is in the storage state. The fixing buckle 15 is made of elastic material and can produce a certain elastic deformation.

[0033] Furthermore, by Figure 1-Figure 4 As shown, in order to fix the patient's arm, each support frame 6 has a fixing strap 16 on the upper side for fixing the arm;

[0034] When in use, the fixing strap 16 is an elastic band that can fix the arm as needed. Specifically, when the patient undergoes a lateral spinal X-ray examination, the patient can pass the arm through the fixing strap 16 so that the support frame 6 and the support plate 5 can provide simple support for the patient's arm and shoulder, which can fix the patient relative to the X-ray machine when taking X-rays and reduce the generation of motion artifacts.

[0035] Furthermore, by Figure 1-Figure 4 To facilitate both the movement and fixation of the device, the support mechanism 7 includes a support foot 17 and a directional wheel 18. The support foot 17 has an inclined surface 19 on its lower side, and the directional wheel 18 is located on the side of the support foot 17 away from the inclined surface 19.

[0036] Furthermore, by Figure 1-Figure 4 It is shown that the support mechanism 7 on the lower side of the first support rod 1 and the support mechanism 7 on the lower side of the second support rod 2 are arranged symmetrically front and rear.

[0037] When in use, since the first support rod 1 and the second support rod 2 are on the same vertical plane when the device is in the stored state, the lower side of each support mechanism 7 (i.e., the lower side of each support foot 17 and the directional wheel 18) is in contact with the ground. The device can then be erected in any position for easy placement and storage. When the device needs to be used, the first support rod 1 needs to have a certain relative angle with the second support rod 2 to unfold the device. When there is a relative angle, there is also an angle of inclination relative to the ground. Therefore, only one of the support feet 17 and directional wheels 18 within the same support mechanism 7 can be in use at any time. One of them is in contact with the ground. Since the support mechanism 7 on the lower side of the first support rod 1 and the support mechanism 7 on the lower side of the second support rod 2 are symmetrically arranged, when the support mechanism 7 on the lower side of the first support rod 1 is fixed to the ground through the inclined surface 19 on the lower side of the support foot 17, the support mechanism 7 on the lower side of the second support rod 2 is also fixed to the ground through the inclined surface 19 on the lower side of the support foot 17. Similarly, when the support mechanism 7 on the lower side of the first support rod 1 is in contact with the ground through the directional wheel 18, the support mechanism 7 on the lower side of the second support rod 2 is also in contact with the ground through the directional wheel 18, which facilitates the movement of the entire device.

[0038] It should be further noted that the support plate 5 and the support frame 6 can be made of appropriate materials as needed, such as lightweight wood, which can reduce the impact on the final product during X-ray inspection.

[0039] In use, the first support rod 1 can be rotated relative to the two second support rods 2 to unfold the device. At this time, the support plate 5 will change from a vertical state to a horizontal state, allowing the device to be moved to a suitable position to support the patient's limbs. After moving to the suitable position, the first support rod 1 can be rotated in the opposite direction relative to the second support rods 2. At this time, each support mechanism 7 will change its contact position with the ground, fixing the entire device and providing more stable support for the patient's limbs. During use, the relative angle between the first support rod 1 and the second support rod 2 can be fixed by the limiting mechanism 4. When the patient undergoes a lateral spinal X-ray examination, the arm can be passed through the fixing strap 16, allowing the support frame 6 and the support plate 5 to provide simple support for the patient's arm and shoulder. This allows the patient to be fixed relative to the X-ray machine during X-ray imaging, reducing motion artifacts. When the patient undergoes a forward spinal X-ray, the corresponding support frame 6 or support plate 5 can also be used to support the patient's shoulder. At this time, the support frame 6 can be placed under the patient's armpit to reduce the risk of limb movement during the examination.

[0040] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively achieves the purpose of providing appropriate upper limb support for patients with scoliosis during examination, reducing the probability of motion artifacts, facilitating the adjustment and storage of the device by staff, making the device more stable when placed, and fixing the patient's arm. It is convenient to move the device and can be fixed at any time.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
