Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a device for improving the accuracy of scoliosis measurement. Background Technology

[0002] Scoliosis is typically measured by taking X-ray images of the spine and then using precise measuring instruments to determine the angle of curvature. However, the X-ray is usually taken in a supine position, which can cause the pelvis to tilt, resulting in a misaligned spine and affecting the accuracy of the measurement results. Utility Model Content

[0003] The purpose of this invention is to provide a device for improving the accuracy of scoliosis measurement, which solves the technical problem in the prior art where the pelvis tends to tilt when the patient is lying supine, causing the spine to be in a crooked state, thus affecting the accuracy of the measurement results.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for improving the accuracy of scoliosis measurement, comprising:

[0005] A shoulder limiting block that fits against the patient's shoulder has a limiting plate located on both sides of the patient's shoulder and movable relative to each other along the side surface of the shoulder limiting block. A foot cover is slidably provided on the limiting plate. An adjustment plate parallel to the shoulder fitting surface is provided on the side surface of the shoulder limiting block away from the shoulder fitting surface.

[0006] A connecting frame is fixedly connected to the foot cover, and an adjustable pelvic positioning plate is hinged on the connecting frame. The hinge shafts on the two connecting frames are slidably disposed at both ends of the pelvic positioning plate.

[0007] Before the foot cover moves towards the shoulder and comes into contact with it, the foot cover moves the pelvic alignment plate towards the adjustment plate. When the pelvis is tilted, the foot cover on the lower pelvic side pulls one end of the pelvic alignment plate to contact the adjustment plate first, while the foot cover on the higher pelvic side pulls the other end of the pelvic alignment plate to pry the lower pelvic side foot cover to move in the opposite direction a certain distance so that the pelvic alignment plate fits against the adjustment plate.

[0008] Preferably, the adjusting plate is symmetrically provided with a limiting post that is slidably disposed at one end in the shoulder limiting block, and the limiting post has slots on both sides in the direction of movement, and an unlocking block is elastically disposed in the slot.

[0009] Preferably, an arc-shaped locking block is elastically provided inside the shoulder limiting block along the moving direction of the limiting plate, and the arc-shaped locking block is engaged with the slot opened on the limiting post.

[0010] Preferably, a triangular wedge is elastically provided inside the limiting post along the moving direction of the limiting post, and the inclined surface of the triangular wedge is fitted with the unlocking block.

[0011] Preferably, a contact rod that penetrates the adjusting plate is fixedly provided on the triangular wedge block.

[0012] In the above technical solution, the device provided by this utility model for improving the accuracy of scoliosis measurement has the following beneficial effects:

[0013] This invention utilizes a limiting plate, foot covers, a pelvic alignment plate, and an adjusting plate. Before the foot covers contact the shoulder, the limiting plate moves the pelvic alignment plate towards the adjusting plate. When the pelvis is tilted, the foot cover on the lower pelvic side pulls one end of the pelvic alignment plate to contact the adjusting plate, while the foot cover on the higher pelvic side pulls the other end of the pelvic alignment plate, causing the lower pelvic side foot cover to move in the opposite direction a short distance. This allows the pelvic alignment plate to fit snugly against the adjusting plate, thereby adjusting the patient's pelvis to a horizontal position and parallel to the shoulders. This further aligns the patient's pelvis, effectively preventing spinal misalignment caused by a tilted pelvis, which could affect measurement results and improve accuracy.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, a device for improving the accuracy of scoliosis measurement includes:

[0023] A shoulder limiting block 7 that fits against the patient's shoulder is provided with a limiting plate 2 located on both sides of the patient's shoulder and moving relative to each other along the side surface of the shoulder limiting block 7. A foot sleeve 8 is slidably provided on the limiting plate 2. An adjustment plate 5 parallel to the shoulder fitting surface is provided on the side surface of the shoulder limiting block 7 away from the shoulder fitting surface.

[0024] A connecting frame 3 is fixedly connected to the foot cover 8. An adjustable pelvic positioning plate 4 is hinged on the connecting frame 3. The hinge shafts on the two connecting frames 3 are slidably set at both ends of the pelvic positioning plate 4.

[0025] Before the limiting plate 2 moves the foot sleeve 8 towards the shoulder and makes contact with the shoulder, the foot sleeve 8 moves the pelvic alignment plate 4 towards the adjusting plate 5. When the pelvis is tilted, the foot sleeve 8 on the lower end of the pelvis pulls one end of the pelvic alignment plate 4 to make contact with the adjusting plate 5 first. The foot sleeve 8 on the higher end of the pelvis pulls the other end of the pelvic alignment plate 4 to pry the lower end of the pelvic side foot sleeve 8 to move in the opposite direction for a distance so that the pelvic alignment plate 4 fits against the adjusting plate 5.

[0026] Specifically, the patient lies supine on the bed 1 with the patient's head in the groove on the shoulder limiting block 7 and the patient's shoulder in contact with the side surface of the shoulder limiting block 7, so that the patient's shoulder is in a horizontal position. Then, the patient's legs are straightened and the feet are put into the foot covers 8.

[0027] Furthermore, the drive electric actuator moves the limiting plate 2 on the bed 1 along the side surface of the shoulder limiting block 7 toward the patient's shoulder. This causes the patient's straightened leg to push the foot sleeve 8 on the limiting plate 2 away from the shoulder limiting block 7. This, in turn, pulls the pelvic alignment plate 4 toward the adjusting plate 5 via the connecting frame 3 fixed on the foot sleeve 8. This ensures that the patient's feet are the same width as their shoulders, thus ensuring that the patient's spine is in a neutral position and preventing incorrect patient posture from affecting the accuracy of the measurement results.

[0028] Furthermore, when the patient's pelvis tilts, before the limiting plate 2 contacts the shoulder, during the process of pulling the pelvic alignment plate 4 towards the adjusting plate 5 via the connecting frame 3 fixed on the foot sleeve 8, the foot sleeve 8 on the lower pelvic side first pulls the same end of the pelvic alignment plate 4 to contact the adjusting plate 5 via the connecting frame 3 on the same side, thus putting the pelvic alignment plate 4 in a tilted state. Meanwhile, the foot sleeve 8 on the higher pelvic side pulls the other end of the pelvic alignment plate 4 towards the adjusting plate 5 via the connecting frame 3. During this process, the foot sleeve 8 moves towards the adjusting plate 5, and the foot sleeve 8 on the higher pelvic side... One end of the pelvic alignment plate 4, connected to the lower end of the pelvic side drive, is used as a fulcrum at its contact point with the adjusting plate 5. By prying one end of the pelvic alignment plate 4 connected to the lower end of the pelvic side drive, the lower end pelvic side foot sleeve 8 is moved in the opposite direction for a certain distance until the pelvic alignment plate 4 is parallel and in contact with the adjusting plate 5. This adjusts the patient's pelvis on both sides to be in a horizontal state and parallel to the shoulders, thereby further aligning the patient's pelvis and effectively preventing the patient's pelvis from being tilted, which would cause the spine to be crooked and affect the measurement results, thus effectively improving the accuracy of the measurement results.

[0029] It should be noted that the hinge shafts on the connecting frame 3 are slidably set at both ends of the pelvic anteroposterior plate 4 so that the pelvic anteroposterior plate 4 can be in an inclined state. By rotating the limiting cap on the hinge shaft, the pelvic anteroposterior plate 4 can be disassembled and installed on the hinge shaft at different positions to adjust the distance between the pelvic anteroposterior plate 4 and the adjusting plate 5 according to the patient's height, so that the pelvic anteroposterior plate 4 can contact the adjusting plate 5 during the process of adjusting the feet and shoulders to be the same width.

[0030] As a further embodiment of this utility model, a limiting post 6 is symmetrically arranged on the adjusting plate 5, with one end slidably disposed in the shoulder limiting block 7. The limiting post 6 has slots on both sides in the direction of movement, and an unlocking block 12 is elastically disposed in the slot.

[0031] As a further embodiment of this utility model, an arc-shaped locking block 11 is elastically provided inside the shoulder limiting block 7 along the moving direction of the limiting plate 2, and the arc-shaped locking block 11 is engaged with the slot opened on the limiting post 6.

[0032] Specifically, the arc-shaped locking block 11 is engaged with the slot of the limiting post 6 to fix the position of the limiting post 6, thereby fixing the position of the adjusting plate 5.

[0033] As a further embodiment of this utility model, a triangular wedge block 10 is elastically provided inside the limiting post 6 along the moving direction of the limiting post 6, and the inclined surface of the triangular wedge block 10 is fitted with the unlocking block 12.

[0034] As a further embodiment of this utility model, a contact rod 9 that penetrates the adjusting plate 5 is fixedly provided on the triangular wedge block 10.

[0035] Specifically, the foot sleeve 8 on the high-end pelvic side moves towards the adjusting plate 5 via the connecting frame 3, pulling the other end of the pelvic alignment plate 4. During this process, one end of the pelvic alignment plate 4, which is connected to the high-end pelvic side, uses its contact point with the adjusting plate 5 as a fulcrum to pry open the other end of the pelvic alignment plate 4, which is connected to the low-end pelvic side, pulling the foot sleeve 8 on the low-end pelvic side in the opposite direction for a certain distance until the pelvic alignment plate 4 and the adjusting plate 5 are parallel and in contact. During this process, the pelvic alignment plate 4 pushes against the contact rod 9, causing the triangular wedge block 10 to move towards the foot sleeve 8 and stretching the first elastic band. The spring, through the inclined surface of the triangular wedge block 10, pushes the unlocking block 12 to move along the inclined surface towards the contact rod 9, and squeezes the second spring, thereby pushing the arc-shaped locking block 11 out of the slot through the unlocking block 12, and squeezing the third spring, thereby unlocking the limiting post 6. When the pelvic alignment plate 4 and the adjusting plate 5 are parallel and in contact, both limiting posts 6 are unlocked. When the adjusting plate 5 is leveling the pelvic alignment plate 4, the adjusting plate 5 is simultaneously released from restriction. As the limiting plate 2 is in contact with the shoulder, the foot sleeve 8 continues to pull the pelvic alignment plate 4 and the adjusting plate 5 to move a distance so that the foot is the same width as the shoulder.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
