Description

Technical Field

[0001] This utility model belongs to the field of ankle radiological diagnosis fixation technology, and in particular relates to a fixation device for ankle radiological diagnosis. Background Technology

[0002] Radiological diagnosis is an important means of determining the specific problem when the ankle is injured or uncomfortable. Radiological diagnoses, such as X-rays or CT scans, require the patient to maintain a specific position to ensure the accuracy and precision of the diagnosis. This is especially true for the complex and critical anatomical location of the ankle, where diagnostic accuracy is paramount. Therefore, immobilizing the patient's ankle is particularly important during radiological diagnosis to avoid image blurring caused by changes in position and thus ensure diagnostic accuracy.

[0003] In order to both fix the patient's ankle and avoid the fixation components from obstructing the ankle and affecting the scanning results, existing products fix the patient's instep and lower leg to restrict the movement of the ankle. However, fixing two parts increases the number of steps and reduces the efficiency of diagnosis. Utility Model Content

[0004] The purpose of this invention is to provide a fixation device for ankle radiological diagnosis that can fix two parts at once, reducing work steps and improving diagnostic efficiency to a certain extent.

[0005] The aforementioned ankle radiological diagnostic fixation device includes a horizontally arranged base plate, a foot plate fixed to the top of the base plate, and sliding plates that can slide along their length on the front and rear side walls of the foot plate. Each sliding plate is hinged with a connecting rod that can swing left and right. A retaining strap for fixing the instep is provided between the two connecting rods. The retaining strap is made of elastic material. The swing ends of the two connecting rods are connected to the same fixing plate for fixing the lower leg. Each connecting rod is hinged with a locking hook, and pins for locking the hooks are fixed to the front and rear side walls of the base plate.

[0006] Furthermore, the front and rear side walls of the foot plate are provided with grooves, and the slide plate is located in the groove and can slide along its length; the cross-sections of the groove and the slide plate are both matching isosceles trapezoidal structures.

[0007] Furthermore, the two skateboards are connected by a connecting plate, which has a "C" shaped structure. The connecting plate fits against the left side wall of the footboard, and a pressing plate is fixed on the connecting plate.

[0008] Furthermore, the fixing plate includes a shell made of plastic material, the swing ends of the two connecting rods are fixed to the outer surface of the shell, and a silicone pad is fixed to the inner surface of the shell; the shell and the silicone pad together form an arc-shaped structure that fits the human lower leg.

[0009] Furthermore, a pad is fixed to the top of the base plate. The pad is made of silicone material, and the top of the pad has an arc-shaped structure that fits the patient's lower leg.

[0010] Furthermore, there are several hooks distributed from left to right; all hooks are fixed to the front and rear side walls of the base plate by connecting seats.

[0011] Furthermore, an arched plate is fixed on the connecting rod corresponding to the instep of the human body, and the two ends of the strap are respectively connected to the two arched plates. The horizontal height of the fixing plate is lower than the horizontal height of the strap.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention uses a sliding plate to drive a connecting rod downwards. While the fixing plate covers the patient's lower leg, the strap tightens the instep of the patient, thus fixing two parts at the same time. This reduces the number of steps required and improves diagnostic efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. 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. Example

[0020] This embodiment describes a fixation device for ankle radiological diagnosis, such as... Figures 1 to 4 As shown, it includes a horizontally set base plate 1, and a foot plate 6 is fixed on the top of the base plate 1. The foot plate 6 is connected to the base plate 1, and the whole structure forms an "L" shape.

[0021] like Figure 2As shown, the front and rear side walls of the footboard 6 are provided with sliding plates 2 that can slide along its length. The front and rear side walls of the footboard 6 are provided with sliding grooves, and the sliding plates 2 are located in the sliding grooves and can slide along its length. The cross-sections of the sliding grooves and the sliding plates 2 are both isosceles trapezoidal structures that match each other.

[0022] like Figure 3 As shown, each of the slide plates 2 is hinged with a connecting rod 7 that can swing left and right. A fixed block is fixed on the slide plate 2. The hinged end of the connecting rod 7 is hinged to the fixed block through a hinge pin 5. When in use, the connecting rod 7 swings around the hinge pin 5 as the center, and can swing from the right side of the foot plate 6 to the left side of the foot plate 6. When the connecting rod 7 is on the left side of the foot plate 6, it is convenient for the patient to place the foot to be diagnosed on the base plate 1, and the sole of the foot is in contact with the right side wall of the foot plate 6.

[0023] like Figure 2 As shown, a strap 13 for securing the instep is provided between the two connecting rods 7. The strap 13 is made of elastic material. An arched plate is fixed to the connecting rod 7 corresponding to the instep. The two ends of the strap 13 are connected to the two arched plates respectively. The horizontal height of the fixing plate 8 is lower than the horizontal height of the strap 13. The purpose of the arched plate is to increase the height of the strap 13, so that the strap 13 can be higher than the horizontal height of the fixing plate 8, which is more in line with ergonomic design. When a person is lying flat, their instep is usually higher than the horizontal height of their lower leg, so the strap 13 used to secure the instep must be higher than the fixing plate 8 used to secure the lower leg.

[0024] During production, the arched plate and connecting rod 7 can be integrated into one piece, making the overall structure more aesthetically pleasing and more stable.

[0025] like Figure 2 and Figure 3 As shown, the swing ends of the two connecting rods 7 are connected to the same fixing plate 8 for fixing the lower leg of the human body. Each connecting rod 7 is hinged with a locking hook 9, and the front and rear side walls of the base plate 1 are fixed with hooks 10 for locking the locking hooks 9.

[0026] The fixation plate 8 includes an outer shell made of plastic. The swing ends of the two connecting rods 7 are fixed to the outer surface of the outer shell, and a silicone pad is fixed to the inner surface of the outer shell. The outer shell and the silicone pad together form an arc-shaped structure that conforms to the human lower leg. The plastic outer shell serves as the skeleton of the fixation plate 8 to ensure the stability of the fixation plate 8 structure, while the silicone pad ensures comfort when fixing the patient's lower leg.

[0027] Both the front and rear connecting rods 7 are locked to the hanging pins 10 via hooks 9, and the patient's lower leg is fixed using the fixing plate 8 in conjunction with the base plate 1. A pad 11, made of silicone material, is fixed to the top of the base plate 1, and the top of the pad 11 has an arc-shaped structure that conforms to the patient's lower leg. The pad 11 and the silicone pad on the fixing plate 8 work together to restrict the movement of the patient's lower leg while avoiding discomfort to the patient.

[0028] Two skateboards 2 are connected by a connecting plate 4, which has a "C" shape. The connecting plate 4 fits against the left side wall of the footboard 6, and a pressing plate 3 is fixed on the connecting plate 4. The two ends of the connecting plate 4 are fixed to the two skateboards 2 respectively. When in use, the two skateboards 2 are connected by the connecting plate 4, which allows them to slide synchronously for better performance.

[0029] During use, the height of the sliding plate 2, adjusting the linkage 7 and the fixed plate 8, can be adjusted up and down to accommodate different patients due to varying leg sizes. The pressing plate 3 increases the patient's operating area, facilitating pressing when the sliding plate 2 moves downwards.

[0030] like Figure 2 As shown, there are several hanging pins 10, distributed sequentially from left to right; all hanging pins 10 are fixed to the front and rear side walls of the base plate 1 via connecting seats 12. The length of the locking hook 9 is fixed. When the hanging pins 10 are locked onto different hanging pins 10 on the left and right sides, it means that the height of the fixing plate 8 is different, which is used to restrict the movement of patients with different leg sizes.

[0031] The pressing plate 3 has threaded holes that connect the left and right sides. A locking screw that is threaded to the threaded hole is inserted into the threaded hole. The locking end of the locking screw rests against the left side wall of the foot plate 6, thereby locking the current position of the connecting plate 4, that is, locking the height of the skateboard 2.

[0032] like Figure 3 and Figure 4 As shown, in actual use, the connecting rod 7 is flipped to the left side of the foot plate 6, making it convenient for the patient to place their lower leg on the base plate 1. Then, the sliding plate 2 is slid upwards so that when the connecting rod 7 is flipped to the right, the retaining strap 13 can pass over the patient's toes. Then, the pressing plate 3 is pressed to make the sliding plate 2 slide downwards, covering the fixing plate 8 on the patient's lower leg. At the same time, as the retaining strap 13 moves downwards, it takes advantage of the fact that the instep of the patient's foot is thinner and thicker, and the retaining strap 13 gradually tightens and fixes the instep of the patient's foot. Finally, the locking hook 9 and the locking screw are locked. The main feature is that the patient's instep and lower leg are fixed in one step by moving the connecting rod 7 downwards, reducing the need for two separate fixing steps, thereby improving the efficiency of radiological diagnosis.

[0033] The patient's ankle is located between the two connecting rods 7, unobstructed by other components, thus avoiding any issues that could affect the scan results.
