Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary device for multi-position X-ray imaging of the foot and ankle. Background Technology

[0002] Current multi-position weight-bearing X-ray imaging techniques for the foot and ankle primarily rely on the strong penetrating power of X-rays, allowing them to pass through the patient's foot and ankle, positioned according to diagnostic needs, and project onto a highly sensitive detector. This process captures the attenuation differences of X-rays as they penetrate tissues of different densities, thereby obtaining clear and detailed images of the bones and surrounding soft tissue structures. This technique has wide applications in foot and ankle surgery, particularly in the diagnosis of foot and ankle diseases, preoperative assessment to determine the extent and severity of lesions, surgical planning and optimization, and postoperative efficacy evaluation, demonstrating irreplaceable clinical significance.

[0003] However, despite the significant success of this technology in clinical applications, its limitations also deserve our serious consideration and attention. Specifically, while existing X-ray imaging techniques can provide images of the foot and ankle, they cannot provide a comprehensive and multi-faceted accurate diagnosis and assessment of foot and ankle lesions. In practice, due to the complex structure of the human foot and ankle and the diversity of lesions, multiple body positions are often required for imaging to obtain more comprehensive diagnostic information.

[0004] For example, when performing tangential X-ray imaging of the sesamoid bones, the patient's ankle needs to be at a certain angle to clearly display the sesamoid bones and surrounding structures. This requires medical staff to use props or place a special pad on the examination table, which the patient then steps on to adjust the ankle angle for imaging. However, some patients, due to physical reasons such as joint stiffness, pain, or poor balance, have difficulty accurately stepping on the pad and maintaining the required position, making the imaging process difficult. In such cases, medical staff often need to spend a lot of time and energy assisting and correcting the patient, which not only increases their workload but also easily leads to deviations in test results due to human factors, thus affecting the accuracy and reliability of the test results. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides a multi-position X-ray imaging auxiliary device for the foot and ankle.

[0006] This utility model provides the following technical solution:

[0007] A multi-position X-ray imaging auxiliary device for the foot and ankle includes a base, a support platform, and an adjustment component.

[0008] The base has a placement slot on its side for vertically placing a flat panel detector; the support platform is disposed on the base and is composed of a first support plate and a second support plate; the adjustment component is disposed between the base and the support platform and is used to drive the first support plate and the second support plate to deflect relative to each other.

[0009] As a further improvement to the above technical solution, the base is provided with a hinge seat, and the ends of the first support plate and the second support plate that are close to each other are hinged to the hinge seat through the same hinge axis; the axis of the hinge axis is parallel to the horizontal plane and parallel to the side of the flat panel detector.

[0010] As a further improvement to the above technical solution, the adjustment component includes a first telescopic cylinder and a second telescopic cylinder. Both the first telescopic cylinder and the second telescopic cylinder are mounted on the base. The telescopic rod of the first telescopic cylinder presses against the end face of the first support plate near the base, and the telescopic rod of the second telescopic cylinder presses against the end face of the second support plate near the base.

[0011] As a further improvement to the above technical solution, the first telescopic cylinder is provided in multiple forms along the axial direction of the hinge shaft.

[0012] As a further improvement to the above technical solution, a support rod is provided on the side of the base adjacent to the placement slot, and a foot is provided on the support rod, with the foot located above the support platform.

[0013] As a further improvement to the above technical solution, the legs are provided in two parts, symmetrically arranged on both sides of the base.

[0014] As a further improvement to the above technical solution, a reinforcing plate is provided between the two opposing support rods.

[0015] As a further improvement to the above technical solution, a handrail is provided at the upper end of the support rod.

[0016] As a further improvement to the above technical solution, the handrail is provided with an anti-slip part.

[0017] As a further improvement to the above technical solution, a step is provided on the side of the base away from the placement groove, and the upper plane of the step is lower than the support platform.

[0018] Compared with related technologies, the beneficial effects of this utility model are:

[0019] The multi-position X-ray imaging auxiliary device for the foot and ankle provided by this utility model is operated as follows when X-ray imaging of the patient's foot and ankle is required:

[0020] First, when a weight-bearing X-ray of both feet and ankles is required, the staff will place the flat panel detector into the slot on the side of the base. Then, using the adjustment components, the first and second support plates of the support platform will be adjusted so that their upper surfaces are flush and the flat panel detector is perpendicular to the upper surface formed by the first and second support plates. Next, the patient will be guided onto the support platform, with their feet a certain distance apart and parallel, to ensure that the X-ray image captures both feet completely and clearly. Then, the X-ray tube for emitting X-rays will be placed behind the patient, and adjustments will be made to ensure that the X-rays emitted by the tube are perpendicular to the detection surface of the flat panel detector, the projection direction is parallel to the ground, and the projection center is aligned with the midpoint of both ankle joints. A large film will be taken, including the lower third of the tibia, to obtain a weight-bearing X-ray image of both ankle joints.

[0021] In addition, when performing tangential X-ray imaging of the foot and ankle sesamoid bones, the staff first places the flat panel detector into the slot on the side of the base. Then, using the adjustment mechanism, the first and second support plates of the support platform are adjusted so that their upper surfaces are flush and the flat panel detector is perpendicular to the upper surface formed by the first and second support plates. The patient is then guided onto the support platform, with their feet a certain distance apart and parallel, facing the flat panel detector. At this point, the adjustment mechanism causes the first and second support plates to deflect relative to each other, raising their far ends, thus achieving the required dorsiflexion angle of the metatarsophalangeal joint without moving the patient. Next, the X-ray tube is positioned behind the patient's foot, with the projection direction parallel to the ground and the projection center precisely aligned with the sesamoid bone region. This setup ensures that the X-rays accurately penetrate the patient's foot and ankle, capturing a clear image of the sesamoid bones. After imaging, a tangential X-ray image of the foot and ankle sesamoid bones is obtained, providing strong support for the doctor's diagnosis.

[0022] As can be seen from the above operation process, the foot and ankle X-ray imaging auxiliary device provided by this utility model has significant advantages. By setting up an adjustment component and using it to flexibly adjust the relative positions of the first and second support plates of the support platform, the device can easily adjust the dorsiflexion angle of the metatarsophalangeal joint according to the needs of the imaging position. This function not only eliminates the need for additional tools but also eliminates the need for the patient to change the support platform, thereby greatly improving the convenience and efficiency of operation. At the same time, this design also effectively improves the patient's treatment comfort and satisfaction, and provides doctors with more accurate and comprehensive X-ray image information for diagnosis.

[0035] Combination Figure 1 , Figure 2 As shown, this embodiment provides a multi-position X-ray imaging auxiliary device for the foot and ankle, including a base 100, a support platform 300, and an adjustment component 400.

[0036] The base 100 has a placement groove 110 on its side, in which the flat panel detector 200 is vertically placed; the support platform 300 is disposed on the base 100, and the support platform 300 is composed of a first support plate 310 and a second support plate 320 spliced ​​together; the adjustment component 400 is disposed between the base 100 and the support platform 300, and the adjustment component 400 is used to drive the first support plate 310 and the second support plate 320 to deflect relative to each other.

[0037] The multi-position X-ray imaging auxiliary device for the foot and ankle provided in this embodiment operates as follows when X-ray imaging of the patient's foot and ankle is required:

[0038] First, when a weight-bearing X-ray of both feet and ankles is required, the staff will place the flat panel detector 200 into the placement slot 110 on the side of the base 100. Then, using the adjustment component 400, the first support plate 310 and the second support plate 320 of the support platform 300 will be adjusted so that the upper surfaces of the first support plate 310 and the second support plate 320 are flush, and the flat panel detector 200 is perpendicular to the upper surface formed by the first support plate 310 and the second support plate 320. Next, the patient is guided onto the support platform 300, and is instructed to keep their feet naturally 10 cm apart and parallel to ensure that the X-ray image can capture the patient's feet completely and clearly. Then, the X-ray tube for emitting X-rays is placed behind the patient, and adjustments are made to ensure that the X-rays emitted by the tube are perpendicular to the detection surface of the flat panel detector 200, the projection direction is parallel to the ground, and the projection center is aligned with the midpoint of both ankle joints. A large film is taken, covering the lower 1 / 3 of the tibia, to obtain a weight-bearing X-ray image of both ankle joints.

[0039] Additionally, when performing tangential X-ray imaging of the foot and ankle bones, the staff first places the flat panel detector 200 into the placement slot 110 on the side of the base 100. Then, using the adjustment component 400, the first support plate 310 and the second support plate 320 of the support platform 300 are adjusted so that their upper surfaces are flush and the flat panel detector 200 is perpendicular to the upper surface formed by the first support plate 310 and the second support plate 320. Subsequently, the patient is guided onto the support platform 300, with their feet naturally separated by 10 cm and parallel, and facing the flat panel detector 200. At this time, the adjustment component 400 drives the first support plate 310 and the second support plate 320 to rotate relative to each other, raising their farthest ends, thus aligning the support platform 300 as follows: Figure 3As shown, this allows the patient's metatarsophalangeal joint to be dorsiflexed at a 50° angle without moving the patient. Next, the X-ray tube is positioned behind the patient's foot, with the projection direction parallel to the ground and the projection center precisely aligned with the sesamoid bone region. This setup ensures that the X-rays accurately penetrate the patient's foot and ankle, capturing clear images of the two sesamoid bones. After imaging, tangential X-ray images of the two sesamoid bones in the foot and ankle are obtained, providing strong support for the doctor's diagnosis.

[0040] In some specific embodiments, the base 100 is provided with a hinge seat 120, and the ends of the first support plate 310 and the second support plate 320 that are close to each other are hinged to the hinge seat 120 through the same hinge shaft 330; the axis of the hinge shaft 330 is parallel to the horizontal plane and parallel to the side of the flat panel detector 200. This hinge method not only ensures the stability and reliability of the support plate during the adjustment process, but also makes the adjustment operation more flexible and convenient. It is worth noting that the axis of the hinge shaft 330 is carefully set to be parallel to the horizontal plane. This design helps to maintain the stability of the support plate during the adjustment process and avoids the support plate shaking or instability caused by the tilt of the axis.

[0041] In some specific embodiments, the adjustment assembly 400 includes a first telescopic cylinder 410 and a second telescopic cylinder 420. Both the first telescopic cylinder 410 and the second telescopic cylinder 420 are mounted on the base 100. The telescopic rod of the first telescopic cylinder 410 presses against the end face of the first support plate 310 near the base 100, and the telescopic rod of the second telescopic cylinder 420 presses against the end face of the second support plate 320 near the base 100. This design not only ensures that the telescopic rod can directly and effectively push the support plate, but also makes the adjustment process more stable and controllable. Specifically, both the first telescopic cylinder 410 and the second telescopic cylinder 420 are hydraulic cylinders. By utilizing the telescopic rods of the first telescopic cylinder 410 and the second telescopic cylinder 420 to extend and retract respectively, the first support plate 310 and the second support plate 320 can be pushed respectively. This adjustment method is not only convenient to operate, greatly reducing the tediousness and inconvenience of manual adjustment, but also improves the accuracy and stability of the adjustment. In practical use, precise adjustment of the support plate position can be achieved simply by controlling the input pressure of the hydraulic cylinder, thereby meeting the needs of different shooting positions. In other embodiments of this utility model, the first telescopic cylinder 410 and the second telescopic cylinder 420 can also be electrically driven telescopic cylinders.

[0042] In some specific embodiments, the top ends of the telescopic rods of the first telescopic cylinder 410 and the second telescopic cylinder 420 are provided with hinged balls, and sliding seats are externally hinged to the hinged balls. The sliding seats respectively abut against the corresponding first support plate 310 or second support plate 320, and the end face of the sliding seat near the first support plate 310 or second support plate 320 is smoothly configured. This design not only effectively extends the service life of this embodiment, but also improves the accuracy and flexibility of adjustment. In actual use, we can find that by adopting the combined design of hinged balls and sliding seats, the friction generated when the telescopic rod pushes the support plate is greatly reduced, thereby reducing wear and noise. At the same time, the sliding characteristics of the sliding seats also make the adjustment process smoother and more stable, improving the patient's imaging experience.

[0043] In some specific embodiments, multiple first telescopic cylinders 410 are provided along the axial direction of the hinge shaft 330, which facilitates improving the support stability of the first telescopic cylinders 410 and the first telescopic cylinders 410 on the first support plate 310 or the second support plate 320.

[0044] In some specific embodiments, a support rod 510 is provided on the side of the base 100 adjacent to the placement slot 110. A tripod 520 is mounted on the support rod 510, and the tripod 520 is located above the support platform 300. Two tripods 520 are provided, symmetrically arranged on both sides of the base 100. The combined use of the tripod 520 and the placement slot 110 facilitates the administration of lateral weight-bearing X-ray imaging of the left and right ankles of the patient. The specific operation process is as follows:

[0045] First, place the flat panel detector 200 into the placement slot 110 on the side of the base 100. Then, use the adjustment component 400 to adjust the first support plate 310 and the second support plate 320 of the support platform 300 so that the upper surfaces of the first support plate 310 and the second support plate 320 are flush, and the flat panel detector 200 is perpendicular to the upper surface formed by the first support plate 310 and the second support plate 320. Then, guide the patient to walk onto the support platform 300, so that the patient's left and right feet stand on the corresponding tripods 520 in turn during the imaging. The X-ray tube used to emit X-rays is about 1.5 meters away from the patient, with the projection direction parallel to the ground and the projection center aligned with the intersection of the extended line of the anterior edge of the tibia and the horizontal line of the medial malleolus. Take a large film, the range of which should include the lower 1 / 3 of the tibia, to obtain a lateral weight-bearing X-ray image of the left or right ankle.

[0046] In some specific embodiments, a reinforcing plate 530 is provided between two opposing support rods 510 to improve the support strength of the support rods 510.

[0047] In some specific embodiments, the upper end of the support rod 510 is provided with a handrail 540, which is convenient for patients who cannot maintain a stable standing posture entirely on their own. Patients can maintain their balance and stability by holding the handrail 540, thus making it more comfortable and safer to perform X-ray imaging. The handrail 540 is provided with an anti-slip part 541, which can effectively increase the friction between the handrail 540 and the patient's palm. Even if the patient's palms are sweaty or their grip is weak, they can still firmly grasp the handrail 540, greatly improving the safety and reliability of use.

[0048] In some specific embodiments, the base 100 has a step 130 on the side away from the placement slot 110, and the upper plane of the step 130 is lower than the support platform 300; this facilitates patients with mobility impairments to walk smoothly onto the support platform 300.

[0049] In some specific embodiments, the base 100, the support platform 300, the adjustment component 400, and other related components are all made of non-metallic materials to ensure normal X-ray penetration and accurate detection results. This material selection is primarily based on the excellent X-ray penetration of non-metallic materials, which minimizes X-ray attenuation or scattering caused by material obstruction during detection. This ensures that X-rays can penetrate the detected area along a predetermined path, completely recording the structural information of the detected part. In this way, image blurring or information loss due to material issues can be effectively avoided, further improving the accuracy and clarity of the detection results and providing doctors with a more reliable and detailed basis for diagnosis.
