[0024] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0025] according to Figure 1 - Figure 6 As shown, this embodiment provides a stretching device for ankle injuries, including a fixing seat 1, a support rod 2, a footrest 3 and a support assembly, wherein a fixing area fixed to the platform is provided in the middle of the fixing seat 1, a column 4 is fixedly installed in the middle of the upper end of the fixing seat 1 through an angle code, a sliding sleeve 5 is provided on the outer sleeve of the column 4, and a support rod 2 is fixedly installed on one side of the sliding sleeve 5;

[0026] The support rod 2 is provided with two sleeve blocks 7 on its exterior, and a connecting seat 26 is fixedly mounted on the top of the two sleeve blocks 7, and a hinge shaft 8 is fixed on the front end of each connecting seat 26;

[0027] The outside of one of the hinge shafts 8 is rotatably connected to a foot rest 3 for placing the patient's foot, a positioning sleeve 11 for fixing the side support strip 10 is fixed to the side of the foot rest 3, and a limiting bolt 12 for fixing the side support strip 10 is threadedly connected to one side of the positioning sleeve 11;

[0028] A fixing support 13 for fixing the sole of the patient's foot is fixed on one side of the upper end of the side support bar 10, and a supporting component for supporting the side support bar 10 is provided on the other side of the upper end of the side support bar 10. Considering that when medical staff take X-rays of the patient's ankle, they need to pull the patient's foot with their hands to make the patient's ankle joint everted, so as to ensure the effect of the film. This operation method is time-consuming and labor-intensive, greatly increases the work intensity of medical staff, and at the same time, it will cause medical staff to be harmed by X-rays. Therefore, this device will be used to improve this situation. The fixing seat 1 will be used to clamp the patient on the X-ray platform where he lies flat, and then the patient will fit the rear end of the foot on it. On the footrest 3, the use position of the fixing support 13 is then adjusted according to the length of the patient's foot. After the adjustment, the Velcro strap 24 will be used to fix the front end of the patient's foot. Then, the support angle of the patient's ankle will be adjusted according to the optimal position for X-ray shooting of the ankle. The inclination of the support assembly will be changed by sliding one of the sets 7, so that the footrest 3, the side headline and the fixing support 13 are tilted to a position where the ankle is completely exposed, thereby facilitating X-ray examination. At the same time, there is no need for medical staff to accompany. At the same time, the material of the parts that come into contact with the patient's foot can be selected to be X-ray transparent material, so as not to affect the patient's X-ray examination.

[0029] Considering that the device needs to be fixed on an X-ray examination platform for the patient to lie flat, a slide rail 15 for the longitudinal movement of the slider 14 is fixed to one side of the middle part of the fixing seat 1, and a resistance block 16 is fixed to one side of the slider 14 by screws, and a rubber block 17 is fixed to the upper end of the resistance block 16 by screws. The fixing seat 1 is clamped on the side of the platform, and then the lifting bolt 18 is tightened. At this time, the resistance block 16 is driven to rise by the tightened lifting bolt 18 so that the resistance block 16 resists to the bottom of the platform to complete the fixing process, which is convenient and quick.

[0030] A lifting bolt 18 is threadedly connected to the middle part of the lower end of the fixing seat 1, and the top of the lifting bolt 18 is rotatably connected to the bottom of the resistance block 16 through a bearing. By setting the bearing, the resistance will not rotate with the rotation of the lifting bolt 18 during the process of screwing the lifting bolt 18.

[0031] Taking into account the patient's comfort during filming, the use height of the support rod 2 will be adjusted according to the patient's needs. A fixing bolt 19 is threadedly connected to one side of the sliding sleeve 5. A resistance arc plate 20 is installed at the end of the fixing bolt 19 through a bearing, and the inner wall curvature of the resistance arc plate 20 matches the outer wall curvature of the column 4. After adjusting to the required height, the fixing bolt 19 will be tightened so that the fixing bolt 19 drives the resistance arc plate 20 to squeeze the column 4 so that the position of the sliding sleeve 5 is fixed. When the position of the sliding sleeve 5 is fixed, the use position of the support rod 2 will be fixed, that is, the patient's feet will be lifted to a comfortable height, thereby completing the subsequent expansion process.

[0032] Taking into account that the smoothness of the movement of the sleeve block 7 will affect the patient's fixed foot, guide grooves for the guide wheel 21 to move are provided at the upper and lower ends of the support rod 2, and the guide wheel 21 is hinged at the middle of the sleeve block 7. The middle part of the bottom end of each sleeve block 7 is threadedly connected with a positioning bolt 22. Therefore, the guide wheel 21 inside the sleeve block 7 is used to move horizontally in the guide groove, so that the sleeve block 7 is in a stable state during the movement process, and the patient's fixed foot will not move during the movement due to the unstable movement process, thereby causing pain.

[0033] Taking into account the need to fix the patient's forefoot and hindfoot to ensure the stability of the foot when fixed, this structure is designed, connecting rings 23 are fixedly installed on both sides of the front end of the fixing bracket 13, and a Velcro strap 24 is fixed to the outside of one of the connecting rings 23, and the Velcro strap 24 is used to fix the patient's forefoot.

[0034] The support assembly is tilted to tilt the fixed support 13, the side support strip 10 and the foot support 3, so that the inner ankle position of the patient is exposed, so that the medical staff can use X-rays to take pictures and examine the patient's ankle. The support assembly includes a sleeve rod 25, an extension rod 9 and an alignment bolt 6. A cavity for stretching the extension rod 9 is opened in the middle of the sleeve rod 25. The end of the extension rod 9 is hinged to the other side of the side support strip 10, and the front end of the sleeve rod 25 is threadedly connected with the alignment bolt 6 for fixing the extension rod 9. When the sleeve block 7 moves to a suitable angle, the extension rod 9 will be stretched from the sleeve rod 25 to a length that matches it. After the stretching is completed, the alignment bolt 6 is screwed in to complete the fixing process.

[0035] The lower end of the sleeve rod 25 is hinged on the other hinge shaft 8 .

[0036] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
