Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary equipment technology, specifically relating to a hip joint frog-position X-ray support with adjustable lower limb external rotation angle. Background Technology

[0002] X-ray is the most basic imaging examination method for diagnosing hip joint diseases. Anteroposterior view of the hip joint can directly show the matching and containment of the acetabulum and femoral head, as well as the superior and inferior direction of the femoral head. Frog position view is taken after the hip joint is flexed, abducted, and externally rotated. This special position allows for better observation of the medial and lateral direction of the femoral head, especially the anteromedial weight-bearing area, which is of great significance for diagnosing hip joint diseases.

[0003] Currently, when taking hip joint frog-position radiographs, the patient lies supine with both hip joints flexed at approximately 45 degrees, both lower limbs externally rotated, and the soles of both feet facing each other. To better observe the femoral head, the external rotation angle of both lower limbs is often about 30 degrees to the table surface. However, maintaining the external rotation angle of the lower limbs in this position requires a certain amount of muscle strength and lower limb stability. Moreover, the optimal external rotation angle of the lower limbs for femoral head exposure varies from patient to patient. These factors greatly affect the imaging effect of frog-position radiographs. Therefore, this device designs a hip joint frog-position X-ray positioning support with an adjustable lower limb external rotation angle. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a hip joint frog-position X-ray support with adjustable lower limb external rotation angle, thereby solving the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: a base plate for placing on the lower limb parts of the bed surface, a footrest for placing the feet, a lower limb resting pad for placing the lower limbs, a lower limb flexion adjustment mechanism for driving the resting pad to move linearly and for the lower limb resting pad to flex, and an angle adjustment mechanism for adjusting the angles of the lower limb resting pads on both sides. The resting pads and the base plate are slidably fitted together. There are two lower limb resting pads, which are symmetrically arranged. The end of the base plate is provided with a fixing block. One end of each of the two lower limb resting pads is rotatably connected to the end of the resting pad, and the other end of each of the two lower limb resting pads is rotatably connected to the fixing block.

The bottom pad and the base plate are slidably fitted together. The vertical foot pad is vertically mounted on the bottom pad. The horizontal foot pad and the vertical foot pad are slidably fitted together. The end of the adjusting bolt passes through the horizontal foot pad and abuts against the upper end of the vertical foot pad, and is threadedly connected to the horizontal foot pad.

[0009] Furthermore, both lower limb support pads include connectors, fittings, calf support pads, thigh support pads, and intra-articular support pads. Two connectors are provided, each rotatably mounted on the bottom pad and the fixing block. Two fittings are provided, each rotatably connected to its corresponding connector. The ends of the calf and thigh support pads are connected to their respective fittings. The calf and thigh support pads are connected by the intra-articular support pads, both rotatably connected to them. Both the calf and thigh support pads are equipped with Velcro straps for securing them to the lower limbs.

[0010] Furthermore, both of the lower leg pads and both of the leg pads are made of acrylic sheet material.

[0011] Furthermore, both angle adjustment mechanisms include an angle adjustment rod, a fixing member, and an angle adjustment knob. The angle adjustment rod passes through the bottom pad and is fixedly connected to the corresponding connecting member. The angle adjustment rod and the bottom pad are threaded together.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] This utility model provides a hip joint frog-position X-ray support with adjustable lower limb external rotation angle, including a base plate 1 for placement on the lower limb part of the bed, a footrest 2 for placing the feet, a lower limb support pad 3 for placing the lower limbs, a lower limb flexion adjustment mechanism 4 for driving the footrest 2 to move linearly and the lower limb support pad 3 to flex, and an angle adjustment mechanism 5 for adjusting the lateral angle of the lower limb support pad 3. The footrest 2 and the base plate 1 are slidably fitted back and forth, and there are two lower limb support pads 3. The lower limb support pads 3 are symmetrically arranged. The end of the base plate 1 is provided with a fixing block 11. One end of each of the two lower limb support pads 3 is rotatably connected to the end of the support pad 2, and the other end of each of the two lower limb support pads 3 is rotatably connected to the fixing block 11. The support pad 2 is sleeved on the lower limb flexion adjustment mechanism 4 and is threadedly connected. There are two angle adjustment mechanisms 5. Each of the two angle adjustment mechanisms 5 is fixedly connected to one end of the corresponding lower limb support pad 3. The two angle adjustment mechanisms 5 are respectively set on the support pad 2 and are threadedly connected.

[0028] This device enables patients to flex both hip joints to approximately 45 degrees and externally rotate both lower limbs at an angle of 30 degrees to the horizontal plane, with both feet facing each other, during hip joint frog-position imaging examinations. It provides support to maintain this posture throughout the examination, preventing patients with weak lower limbs from being unable to assume this position and affecting their examination results. This allows for optimal exposure of the femoral head during imaging, improving imaging quality and enabling better assessment of the patient's condition.

[0029] Reference Figure 8As shown, this device can fix the connector 31 to the required bed frame using bolts or any other fixing method, so that the two lower limb support pads 3 are directly in a frog-like position. Thus, during the hip joint frog-like position imaging process, the patient can lie directly on the bed frame, and the lower limbs can be supported by the shape formed by the corresponding lower limb support pads 3. This avoids the situation where patients with weak lower limbs cannot form this position, which would affect their examination results. It achieves the best exposure of the femoral head during the examination, improving the imaging effect and allowing for better examination of the patient's condition.

[0030] All components in this device are made of non-metallic materials to avoid affecting subsequent normal treatment.

[0031] In a further preferred embodiment of the present invention, the end of the base plate 1 is provided with a groove 12 for a person's buttocks to rest on, and the groove 12 is provided with a flexible layer.

[0032] When performing hip joint frog-position radiographic examination on a patient, the device can be placed on the bed first. Then, the patient's buttocks are pressed into the groove 12. The groove 12 has a flexible layer to provide comfort for the patient. By pressing the buttocks into the groove 12, the patient can use their own weight to press the device down and provide fixation. Therefore, the device does not need to be fixed to the bed in other ways, making it more convenient to take out and put in.

[0033] In a further preferred embodiment of this utility model, the padding mat 2 includes a bottom pad 21, a horizontal foot pad 22, a vertical foot pad 23, and an adjusting bolt 24. The bottom pad 21 is sleeved on the screw 41 and is threadedly connected. The bottom pad 21 and the base plate 1 are configured to slide back and forth. The vertical foot pad 23 is vertically disposed on the bottom pad 21. The horizontal foot pad 22 and the vertical foot pad 23 are configured to slide back and forth. The end of the adjusting bolt 24 passes through the horizontal foot pad 22 and abuts against the upper end of the vertical foot pad 23 and is threadedly connected to the horizontal foot pad 22.

[0034] Since the length of each patient's lower limb is different, in order to accommodate patients with different lower limb lengths, after the patient's buttocks are placed in the groove 12, their lower limbs are straightened so that the patient's two feet are in contact with the horizontal foot pad 22. If they are not in contact, the adjusting bolt 24 can be rotated so that the end of the adjusting bolt 24 is no longer in contact with the upper end of the vertical foot pad 23. At this time, the horizontal foot pad 22 is moved towards the patient's foot so that the horizontal foot pad 22 is in contact with the foot. Then, the adjusting bolt 24 is rotated again so that the end of the adjusting bolt 24 is in contact with the upper end of the vertical foot pad 23 again. This makes it suitable for patients with different lower limb lengths, thus facilitating its widespread use.

[0035] In a further preferred embodiment of this utility model, the lower limb flexion adjustment mechanism 4 includes a screw 41 and an adjustment knob 42. The end of the screw 41 is rotatably connected to the fixed block 11, and the head end of the screw 41 is rotatably connected to the head end of the base plate 1. The adjustment knob 42 is located at the head end of the screw 41. Each of the two lower limb support pads 3 includes a connector 31, a mating part 32, a calf support pad 33, a thigh support pad 34, and an inner joint support pad 35. Two connectors 31 are provided, and the two connectors 31 are respectively rotatably mounted on... On the bottom pad 21 and the fixing block 11, there are two mating parts 32. The two mating parts 32 are rotatably connected to the corresponding connecting parts 31. The ends of the calf pad 33 and the thigh pad 34 are connected to the corresponding mating parts 32. The calf pad 33 and the thigh pad 34 are connected by the joint inner side pad 35. The calf pad 33 and the thigh pad 34 are rotatably connected to the joint inner side pad 35. The calf pad 33 and the thigh pad 34 are both provided with Velcro straps for fixing to the lower limbs.

[0036] Reference Figure 1 and Figure 2 As shown, when the patient's lower limbs are straight and the soles of their feet are against the transverse foot pads 22, the patient's lower limbs are connected to the corresponding calf pads 33 and thigh pads 34 by the corresponding Velcro straps. Turning the adjustment knob 42 causes the screw 41 to rotate, which in turn moves the pads 2 toward the patient's buttocks. The movement of the pads 2 pushes the two lower limb pads 3. Through the connection relationship of the connectors 31, mating parts 32, calf pads 33, thigh pads 34 and the inner joint pads 35 in the lower limb pads 3, the calf pads 33 and thigh pads 34 will eventually form a triangular shape from a straight line, thereby flexing the patient's lower limbs at an angle of about 45 degrees. At this time, the patient's feet are placed on the bottom pad 21.

[0037] In a further preferred embodiment of this utility model, both of the lower leg pads 33 and the two leg pads 2 are made of acrylic sheet material;

[0038] The two lower leg support pads 33 and two leg support pads 2 are both made of acrylic sheets, which will not affect the effect of blocking the lower limbs during the imaging examination.

[0039] In a further preferred embodiment of this utility model, each of the two angle adjustment mechanisms 5 includes an angle adjustment rod 51, a fixing member 52, and an angle adjustment knob 53. The angle adjustment rod 51 passes through the bottom pad 21 and is fixedly connected to the corresponding connecting member 31. The angle adjustment rod 51 and the bottom pad 21 are threadedly connected. The fixing member 52 is sleeved on the angle adjustment rod 51 and is threadedly connected. The fixing member 52 abuts against the side end of the bottom pad 21. The angle adjustment knob 53 is located at the head end of the angle adjustment rod 51 and has an angle scale value.

[0040] Reference Figure 2 and Figure 5 As shown, when the patient's lower limbs are flexed at approximately 45 degrees, the fixing element 52 can be rotated to disengage them from the bottom pad 21. Then, the corresponding angle adjustment knob 53 is rotated outward by 60 degrees. When rotating the angle, the required angle can be accurately rotated using the corresponding angle scale values ​​on the two angle adjustment knobs 53. The rotation of the two angle adjustment knobs 53 will drive the corresponding angle adjustment rod 51 to rotate. After rotating 60 degrees, the two lower limb support pads 3 will also rotate 60 degrees, thus causing the lower limbs on the two lower limb support pads 3 to also rotate 60 degrees. Then, the fixing element 52 is rotated to contact the side of the bottom pad 21 to fix the lowering adjustment rod. At this time, the patient's hip joints are flexed at approximately 45 degrees, and the angle between the external rotation of the two lower limbs and the horizontal plane is 30 degrees, with the soles of both feet contacting each other on the vertical foot pad 23. This achieves the adjustment of the patient's lower limbs into a frog-like position. During the examination, the patient's femoral head is in the best exposed state for imaging, improving the imaging effect and allowing for better examination of the patient's condition.

[0041] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
